     the replacing mechanism comprises a synchronization disc; a large chamfer is arranged at center of a rear end of the synchronization disc; a plurality of replacing grooves are formed in the synchronization disc around the axis; each replacing groove is fixedly connected with a replacing plate; each replacing plate is slidably connected with a wire winding column; a bottom end of each wire winding column is in contact with one end of a contact rod; the middle of each contact rod is rotatably connected with an end surface of the synchronization disc; other end of each contact rod is in contact connection with an outer wall of the transmission steel pipe; a sliding groove is axially formed on the transmission steel pipe; clamping bars are rotatably arranged in the sliding groove; 
     a gradient groove is formed in an end surface close to the rotating disc of the synchronization disc; the gradient groove gradually becomes shallow as going further away from an axis of the synchronization disc; an inner bottom surface of the gradient groove is slidably connected with a synchronization block; side walls close to the axis of the synchronization block and the gradient groove are respectively fixedly connected with two ends of a centrifugal spring; a synchronization ring-shaped groove that is coaxial with the synchronization disc is formed in middle of the synchronization disc; a synchronization clamping groove that matches with the synchronization block is formed in a side wall close to the synchronization disc of the rotating disc; an end surface close to the synchronization disc of the rotating disc is fixedly connected with a synchronization ring-shaped block corresponding to the synchronization ring-shaped groove; and 
     the driving mechanism comprises a synchronization belt that is sleeved on an outer side of an output shaft passing through the bracket of the motor; the synchronization belt passes through an avoiding hole of the loading plate to connect to a transmission shaft of a transmission assembly; the transmission assembly transmits power to shafts passing through the loading plate of the wire pulling rollers; and two wire pulling rollers are respectively coaxially and fixedly connected with a synchronization gear; and the synchronization gears are engaged with each other. 
     In operation, the equipment is assembled and fixed; the cable core passes through the transmission steel pipe and the wire pulling rollers in turn; a plurality of sub-wires pass through the winding mechanism and are wound on the outer side of the cable core; the motor is started to rotate clockwise (see from the right side of  FIG. 4 ), so that the motor drives the transmission steel pipe to rotate anticlockwise; the transmission steel pipe rotates to drive the rotating disc to rotate and also drive the winding mechanism to rotate at the same time; meanwhile, the motor drives the transmission assembly through the synchronization belt to operate; the transmission assembly drives a wire pulling roller on the left side to rotate anticlockwise (as shown in  FIG. 4 ); the lower ends of the two wire pulling rollers rotate with the same speeds by means of the synchronization gears so as to pulling the wound cables to a next process; after sub-wires on the wire winding column in a working position are used up, the batching motor is started to rotate; the batching motor drives the wire storage plate through the screws to move upward along the wire storage slot such that a fully-loaded wire winding column moves upward to be close to the bottom end of the wire winding column that is used up; the upper end of the lower wire winding column is inserted into the center hole of the upper wire winding column; under the action of friction force, the upper wire winding column can enable the lower wire winding column to rotate (as shown in  FIG. 3 ); when the rotating speed of the lower wire winding columns gradually approaches that of the upper wire winding columns, the batching motor continues to rotate so that the locking block of the lower wire winding columns engages with the locking groove of the upper wire winding column; at this moment, the eddy current coil is started so that a tin-coated joint of the lower wire winding column is connected with the tail end of the upper wire winding column. As the winding continues, the batching motor continues to operate to drive the fully-loaded lower wire winding column moves up along the side wall of the wire storage slot, such that the concave ring-shaped groove of the empty upper wire winding column squeezes the steel balls and the steel balls further squeeze the compression springs to retract to the squeezing groove; as the batching motor continues to move, the fully-loaded wire winding columns squeezes the empty wire winding column out of the through hole at the top and the empty wire winding column slides out the rotating disc; the concave ring-shaped grooves at the upper end of the fully-loaded wire winding column is clamped into the steel balls to complete positioning (as shown in  FIGS. 2 and 3 , the locking block and the locking groove are meshed with each other, so that the previously positioned wire heads and the wire tails are folded with each other; the effect of welding without shutdown is achieved, so that the technical effect of changing the wires without shutdown is achieved); as the fully-loaded wire winding column are successively positioned, the batching motor rotates reversely such that the wire storage plate fall to an initial position. 
     When the batching motor rotates reversely, the synchronization disc is pushed by an external force to move toward the rotating disc along the axis of the transmission steel pipe; at the same time, the contact rods slide along the outer wall of the transmission steel pipe. When the synchronization ring-shaped groove on the synchronization disc is in contact with the synchronization ring-shaped block, the rotating disc starts to accelerate the synchronization disc by friction force; the synchronization block in the gradient groove of the synchronization disc is subjected to centrifugal force and slides toward the outer ring against the force of the centrifugal spring, so that the synchronization block slides to the outer side along the gradient groove; when the rotating speed is nearly close (as show in  FIGS. 6 and 7 , by means of the centrifugal force from the rotating of the rotating disc, the synchronization block is thrown to the outer side of the synchronization disc, the synchronization block is clamped with the synchronization clamping groove, and the moment arm for driving the synchronization disc by the rotating disc is increased; in this way, the equipment damage caused by driving the synchronization disc and the rotating disc to move only through the friction force is avoided, and inaccurate positioning between the synchronization disc and the rotating disc is avoided), the synchronization block is clamped into the synchronization clamping groove so as to enable the synchronization disc and the rotating disc to rotate at the same speed; the synchronization disc is continuously pushed by the external force such that the synchronization disc attaches to the rotating disc; meanwhile, the tail end of the clamping bar rotates as the transmission steel pipe with a centripetal force that is kept outward all the time; when the large chamfer of the synchronization disc passes through the tail end of the clamping bar (as shown in  FIGS. 4 and 5 ), the clamping bars is no longer restrained by an outside hole, from which the synchronization disc is sleeved at the center on the transmission steel pipe; when the synchronization disc and the rotating disc rotate at the same speed, the clamping bars are determined to be opposite to the contact rods; the clamping bars are unfolded by the centripetal force; as the rotating disc continues to axially slide along the transmission steel pipe, the tail ends of the clamping bars push the contact rods to rotate around the hinged joints so as to push the fully-loaded wire winding columns on the synchronization disc to the upper end surfaces of the wire storage plate, so that the fully-loaded wire winding columns are in preparation states; at the moment, the external force is used for driving the synchronization disc to move backwards again and separate from the rotating disc; the moving states of the parts are opposite; repeated description is not made herein; wire batching of the fully-loaded wire winding columns is carried out after waiting until the synchronization disc is static; and the processes are circulated in turn. 
     With driving of the synchronization disc and the rotating disc, the wire winding column is prepared for batching; with operations of the eddy current coils and the batching motor, the empty wire winding column is replaced with a fully-loaded wire winding column without shutdown. Thus, the equipment is capable of batching without shutdown in the running process, and the problems of poor work sustainability and low working efficiency of the equipment caused by repeatedly batching and shutting down are effectively solved. 
     As a further solution of the present application, the winding mechanism includes a wire winding disc; the wire winding disc is coaxially arranged on an outer wall of the transmission steel pipe; threading slots are formed in the wire winding disc; an outer wall of the wire winding disc is rotatably connected with an upper end surface of the loading plate by a bracket plate; an outer toothed plate is rotatably connected in each threading slot; an outer side of each outer toothed plate engages with a driving gear; the driving gear is rotatably connected in the wire winding disc; an outer wall of each driving gear is fixedly connected with a shifting rod; the shifting rod is slidably connected in a groove on an outer side of the threading slot; and a torsion spring is connected between an axis of the driving gear and the wire winding disc. 
     In operation, the sub-wires are directly pulled to the sides of the threading slots; the sub-wires are directly pulled to the middle parts of the threading slots; the sub-wires touch the shifting rods; the driving gears rotate anticlockwise when the shifting rods are shifted; the driving gears rotate and drive the outer toothed plates to rotate clockwise by overcoming the torsion of the torsion springs (as shown in  FIG. 9  and seen from the right side); when the outer toothed plates rotate, the threading slots are opened; when the sub-wires are pulled to the middlemost parts of the threading slots, the driving gears rotate clockwise again under action of the force of the torsion springs, so that the outer toothed plates rotate clockwise to be closed so as to clamp the sub-wires in the middle parts of the threading slots. 
     The shifting rods rotate to drive the outer toothed plates to rotate, so that the sub-wires can be directly pulled from the side of the wire winding disc to the middle parts of the threading slots without passing through the through holes, and the problems that the inconvenience is caused, the time is wasted and the working efficiency is reduced in the threading process are effectively solved. 
     As a further solution of the present application, the surface of each threading slot is covered with the friction reducing material, so that the friction is reduced, and the service life of the equipment is prolonged. 
     As a further solution of the present application, each shifting rod is made of the friction reducing material, so that the friction is reduced, and the service life of the equipment is prolonged. 
     As a further solution of the present application, the motor adopts a speed reducing motor, so that the torque is increased, the equipment speed is reduced, and the problem of equipment shutdown caused when the replaced wire winding columns are thrown out due to excessively great centrifugal force can be avoided.

     In operation, the equipment is assembled and fixed; the cable core passes through the transmission steel pipe  14  and the wire pulling rollers  13  in turn; a plurality of sub-wires pass through the winding mechanism  7  and are wound on the outer side of the cable core; the motor  11  is started to rotate clockwise (see from the right side of  FIG. 4 ), so that the motor  11  drives the transmission steel pipe  14  to rotate anticlockwise; the transmission steel pipe  14  rotates to drive the rotating disc  21  to rotate and also drive the winding mechanism  7  to rotate at the same time; meanwhile, the motor  11  drives the transmission assembly  62  through the synchronization belt  61  to operate; the transmission assembly  62  drives a wire pulling roller  13  on the left side to rotate anticlockwise (as shown in  FIG. 4 ); the lower ends of the two wire pulling rollers  13  rotate with the same speeds by means of the synchronization gears  63  so as to pulling the wound cables to a next process; after sub-wires on the wire winding column  26  in a working position are used up, the batching motor  15  is started to rotate; the batching motor  15  drives the wire storage plate  24  through the screws  25  to move upward along the wire storage slot  22  such that a fully-loaded wire winding column  26  moves upward to be close to the bottom end of the wire winding column  26  that is used up; the upper end of the lower wire winding column  26  is inserted into the center hole of the upper wire winding column  26 ; under the action of friction force, the upper wire winding column can enable the lower wire winding column  26  to rotate (as shown in  FIG. 3 ); when the rotating speed of the lower wire winding columns  26  gradually approaches that of the upper wire winding columns  26 , the batching motor  15  continues to rotate so that the locking block  262  of the lower wire winding columns  26  engages with the locking groove  263  of the upper wire winding column  26 ; at this moment, the eddy current coil  30  is started so that a tin-coated joint of the lower wire winding column  26  is connected with the tail end of the upper wire winding column  26 . As the winding continues, the batching motor  15  continues to operate to drive the fully-loaded lower wire winding column  26  moves up along the side wall of the wire storage slot  22 , such that the concave ring-shaped groove  261  of the empty upper wire winding column  26  squeezes the steel balls  29  and the steel balls  29  further squeeze the compression springs  28  to retract to the squeezing groove; as the batching motor  15  continues to move, the fully-loaded wire winding columns  26  squeezes the empty wire winding column  26  out of the through hole  27  at the top and the empty wire winding column  26  slides out the rotating disc  21 ; the concave ring-shaped grooves  261  at the upper end of the fully-loaded wire winding column  26  is clamped into the steel balls  29  to complete positioning (as shown in  FIGS. 2 and 3 , the locking block  262  and the locking groove  263  are meshed with each other, so that the previously positioned wire heads and the wire tails are folded with each other; the effect of welding without shutdown is achieved, so that the technical effect of changing the wires without shutdown is achieved); as the fully-loaded wire winding column  26  are successively positioned, the batching motor  15  rotates reversely such that the wire storage plate  24  fall to an initial position. 
     When the batching motor  15  rotates reversely, the synchronization disc  41  is pushed by an external force to move toward the rotating disc  21  along the axis of the transmission steel pipe  14 ; at the same time, the contact rods  44  slide along the outer wall of the transmission steel pipe  14 . When the synchronization ring-shaped groove  54  on the synchronization disc  41  is in contact with the synchronization ring-shaped block  56 , the rotating disc  21  starts to accelerate the synchronization disc  41  by friction force; the synchronization block  52  in the gradient groove  51  of the synchronization disc  41  is subjected to centrifugal force and slides toward the outer ring against the force of the centrifugal spring  53 , so that the synchronization block  52  slides to the outer side along the gradient groove  51 ; when the rotating speed is nearly close (as show in  FIGS. 6 and 7 , by means of the centrifugal force from the rotating of the rotating disc, the synchronization block  52  is thrown to the outer side of the synchronization disc  41 , the synchronization block  52  is clamped with the synchronization clamping groove  55 , and the moment arm for driving the synchronization disc  41  by the rotating disc  21  is increased; in this way, the equipment damage caused by driving the synchronization disc  41  and the rotating disc  21  to move only through the friction force is avoided, and inaccurate positioning between the synchronization disc  41  and the rotating disc  21  is avoided), the synchronization block  52  is clamped into the synchronization clamping groove  55  so as to enable the synchronization disc  41  and the rotating disc  21  to rotate at the same speed; the synchronization disc  41  is continuously pushed by the external force such that the synchronization disc  41  attaches to the rotating disc  21 ; meanwhile, the tail end of the clamping bar  46  rotates as the transmission steel pipe  14  with a centripetal force that is kept outward all the time; when the large chamfer of the synchronization disc  41  passes through the tail end of the clamping bar  46  (as shown in  FIGS. 4 and 5 ), the clamping bars  46  is no longer restrained by an outside hole, from which the synchronization disc  41  is sleeved at the center on the transmission steel pipe  14 ; when the synchronization disc  41  and the rotating disc  21  rotate at the same speed, the clamping bars  46  are determined to be opposite to the contact rods  44 ; the clamping bars  46  are unfolded by the centripetal force; as the rotating disc  21  continues to axially slide along the transmission steel pipe  14 , the tail ends of the clamping bars  46  push the contact rods  44  to rotate around the hinged joints so as to push the fully-loaded wire winding columns  26  on the synchronization disc  41  to the upper end surfaces of the wire storage plate  24 , so that the fully-loaded wire winding columns  26  are in preparation states; at the moment, the external force is used for driving the synchronization disc  41  to move backwards again and separate from the rotating disc  21 ; the moving states of the parts are opposite; repeated description is not made herein; wire batching of the fully-loaded wire winding columns  26  is carried out after waiting until the synchronization disc  41  is static; and the processes are circulated in turn.

Thus, the equipment is capable of batching without shutdown in the running process, and the problems of poor work sustainability and low working efficiency of the equipment caused by repeatedly batching and shutting down are effectively solved. 
     As a further solution of the present application, the winding mechanism  7  includes a wire winding disc  71 ; the wire winding disc  71  is coaxially arranged on an outer wall of the transmission steel pipe  14 ; threading slots  72  are formed in the wire winding disc  71 ; an outer wall of the wire winding disc  71  is rotatably connected with an upper end surface of the loading plate  12  by a bracket plate; an outer toothed plate  73  is rotatably connected in each threading slot  72 ; an outer side of each outer toothed plate  73  engages with a driving gear  74 ; the driving gear  74  is rotatably connected in the wire winding disc  71 ; an outer wall of each driving gear  74  is fixedly connected with a shifting rod  75 ; the shifting rod  75  is slidably connected in a groove on an outer side of the threading slot  72 ; and a torsion spring  76  is connected between an axis of the driving gear  74  and the wire winding disc  71 . 
     In operation, the sub-wires are directly pulled to the sides of the threading slots  72 ; the sub-wires are directly pulled to the middle parts of the threading slots  72 ; the sub-wires touch the shifting rods  75 ; the driving gears  74  rotate anticlockwise when the shifting rods  75  are shifted; the driving gears  74  rotate and drive the outer toothed plates  73  to rotate clockwise by overcoming the torsion of the torsion springs  76  (as shown in  FIG. 9  and seen from the right side); when the outer toothed plates  73  rotate, the threading slots  72  are opened; when the sub-wires are pulled to the middlemost parts of the threading slots  72 , the driving gears  74  rotate clockwise again under action of the force of the torsion springs  76 , so that the outer toothed plates  73  rotate clockwise to be closed so as to clamp the sub-wires in the middle parts of the threading slots  72 . 
     The shifting rods  75  rotate to drive the outer toothed plates  73  to rotate, so that the sub-wires can be directly pulled from the side of the wire winding disc  71  to the middle parts of the threading slots  72  without passing through the through holes, and the problems that the inconvenience is caused, the time is wasted and the working efficiency is reduced in the threading process are effectively solved. 
     As a further solution of the present application, the surface of each threading slot  72  is covered with a friction reducing material, so that the friction is reduced, and the service life of the equipment is prolonged. 
     As a further solution of the present application, each shifting rod  75  is made of the friction reducing material, so that the friction is reduced, and the service life of the equipment is prolonged. 
     As a further solution of the present application, the motor  11  adopts a speed reducing motor, so that the torque is increased, the equipment speed is reduced, and the problem of equipment shutdown caused when the replaced wire winding columns  26  are thrown out due to excessively great centrifugal force can be avoided. 
     As a further solution of the present application, grooves are formed in the wire storage plate  24  and the replacing plates  43 , so that the wire winding columns can accurately and quickly reach the wire storage plate  24  from the replacing plates  43 , the working errors are reduced, and the problem of low working efficiency caused by shutdown can be avoided. 
     The working principle is as follows: when working, the equipment is assembled and fixed; the cable core passes through the transmission steel pipe  14  and then passes through the wire pulling rollers  13 ; a plurality of sub-wires pass through the winding mechanism  7  and are wound on the outer side of the cable core; then the motor  11  is started to rotate clockwise (see from the right side of  FIG. 4 ), so that the motor  11  drives the transmission steel pipe  14  to anticlockwise rotate; the transmission steel pipe  14  rotates and firstly drives the rotating disc  21  to rotate and also drives the winding mechanism  7  to rotate at the same time; meanwhile, the motor  11  drives the transmission assembly  62  to work through the synchronization belt  61 ; the transmission assembly  62  drives a wire pulling roller  13  on the left side to rotate anticlockwise (as shown in  FIG. 4 ); the lower ends of the two wire pulling rollers  13  are used for achieving same left and right speeds through the synchronization gears  63  and pulling the wound cables to a next process; after sub-wires on the wire winding column  26  in a working position are used up, the batching motor  15  is started to rotate; the batching motor  15  is used for driving the wire storage plate  24  to move upward along the wire storage slot  22  through the screws  25 ; the fully-loaded wire winding columns  26  move upward to be close to the bottom ends of the wire winding columns  26  which are used up; the ends of the upper ends of the wire winding columns  26  are inserted into the middle holes of the wire winding columns  26  on the upper ends; under the action of friction force, the upper wire winding columns can enable the lower wire winding columns  26  to start rotating (shown in  FIG. 3 ); when the rotating speeds of the lower wire winding columns  26  are gradually close to that of the upper wire winding columns  26 , the batching motor  15  continues to rotate, so that the locking blocks  262  of the lower wire winding columns  26  are combined with the locking grooves  263  of the upper wire winding columns  26 ; at the moment, the eddy current coils  30  are started, so that tin-coated joints of the wire winding columns  26  at the lower ends are connected with tails of the wire winding columns  26  at the upper ends; as winding continues to carry out, the batching motor  15  continues to carry out; the fully-loaded wire winding columns  26  at the lower ends continue to jack up along the side walls of the wire storage slot  22 ; the concave ring-shaped grooves  261  of empty wire winding columns  26  at the upper ends squeeze the steel balls  29 , so that the steel balls  29  squeeze the compression springs  28  to retract to the formed squeezing grooves; as the batching motor  15  continues to move, the fully-loaded wire winding columns  26  squeezes the empty wire winding columns  26  from the through holes  27  in the upper part; the rotating disc  21  slides out; the concave ring-shaped grooves  261  in the upper ends of the fully-loaded wire winding columns  26  are clamped into the steel balls  29  to complete positioning (as shown in  FIG. 2  and  FIG. 3 ), the locking blocks  262  and the locking grooves  263  are meshed with each other, so that the previously positioned wire heads and the wire tails are folded with each other; the effect of welding without shutdown is achieved, so that the technical effect of changing the wires without shutdown is achieved); as the fully-loaded wire winding columns  26  are successively positioned, the batching motor  15  rotates reversely, the wire storage plate  24  fall to an initial position; when the batching motor  15  rotates reversely, the external force is used for pushing the synchronization disc  41  to the rotating disc  21  along the axis of the transmission steel pipe  14 ; at the same time, the contact rods  44  slide along the outer wall of the transmission steel pipe  14 ; when the synchronization ring-shaped groove  54  in the synchronization disc  41  is in contact with the synchronization ring-shaped block  56 ; the rotating disc  21  starts to accelerate the synchronization disc  41  through friction force; the synchronization block  52  in the gradient groove  51  of the synchronization disc  41  can slide to an outer ring by overcoming the force of the centrifugal spring  53  under the action of the centrifugal force, so that the synchronization block  52  slides to the outer side along the gradient groove  51 ; when the rotating speed is nearly close (as show in  FIG. 6  and  FIG. 7 , the effect of the centrifugal force is used for throwing the synchronization block  52  to the outer side of the synchronization disc  41  by using the rotating speed of the rotating disc, the synchronization block  52  is clamped with the synchronization clamping groove  55 , the moment arm for driving the synchronization disc  41  of the rotating disc  21  is increased, the equipment damage caused by driving the synchronization disc  41  and the rotating disc  21  to move only through the friction force is avoided, and inaccurate positioning between the synchronization disc  41  and the rotating disc  21  is avoided); the synchronization block  52  is clamped into the synchronization clamping groove  55  so as to enable the synchronization disc  41  and the rotating disc  21  to rotate at the same speed; the external force is used for continuously pushing the synchronization disc  41  and enabling the synchronization disc  41  and the rotating disc  21  to be attached; meanwhile, the tail ends of the clamping bars  46  rotate along the transmission steel pipe  14 , so that the centripetal force is kept outward all the time; when the large chamfer of the synchronization disc  41  passes through the tail ends of the clamping bars  46  (as shown in  FIG. 4  and  FIG. 5 ), the clamping bars  46  cannot be restrained by the center of the synchronization disc  41  sleeved on an outer side hole of the transmission steel pipe  14 ; when the synchronization disc  41  and the rotating disc  21  rotate, the clamping bars  46  are determined to be opposite to the positions of the contact rods  44 ; the clamping bars  46  start to be unfolded by the centripetal force; as the rotating disc  21  continues to axially slide along the transmission steel pipe  14 , the tail ends of the clamping bars  46  push the contact rods  44  to rotate around the hinged joint so as to push the fully-loaded wire winding columns  26  on the synchronization disc  41  to the upper end surfaces of the wire storage plate  24 , so that the fully-loaded wire winding columns  26  are in preparation states; at the moment, the external force is used for driving the synchronization disc  41  to move backwards again and separate from the rotating disc  21 ; the moving states of the parts are opposite; repeated description is not made herein; wire batching of the fully-loaded wire winding columns  26  is carried out after waiting until the synchronization disc  41  is static; and the processes are circulated in turn.
