The supporting element  231  can be secured on the fixing column  21 , whereby the feeding assembly  23  can communicate with the fixing column  21  (as shown in  FIG. 1 ). The first disk  233  and second disk  235  can be positioned on the two sides of the supporting element  231  and spaced apart from each other. The first feeding belt  200  can be coiled on the first disk  233 , and the second feeding belt  300  can be coiled on the second disk  235 . The first driver  234  can be positioned under the first disk  233 , and the second driver  236  can be positioned under the second disk  235 . The first driver  234  can be configured to drive the first disk  233  to rotate and transmit the first feeding belt  200  to the positioning mechanism  30  (as shown in  FIG. 1 ). The second driver  236  can be configured to drive the second disk  235  to rotate and transmit the second feeding belt  300  to the positioning mechanism  30  (as shown in  FIG. 1 ).

The guiding element  239  can be configured to adjust the motion of the first feeding belt  200  and second feeding belt  300 . The first feeding belt  200  and second feeding belt  300  transmitted from the feeding mechanism  20  can be further secured by the positioning mechanism  30  (as shown in  FIG. 1 ). 
       FIG. 3  illustrates that the positioning assembly  33  can include an assembly plate  331 , a supporting block  333 , a positioning element  335 ; a positioning block  337 , and a pushing element  339 . The assembly plate  331  can be fixed on the fixing plate  31 (as shown in  FIG. 1 ). The supporting block  333  and positioning block  337  can be fixed on the assembly plate  331 , and the supporting block  333  can be adjacent to the positioning block  337 . The positioning element  335  can be installed on the supporting block  333  facing the guiding element  239  to receive the first feeding belt  200  and second feeding belt  300  adjusted by the guiding element  239  (as shown in  FIGS. 1-2 ). 
     The positioning block  337  can include a receiving groove  3371  configured to receiving the first feeding belt  200  and second feeding belt  300  (as shown in  FIG. 1 ). The pushing element  339  can be installed under the positioning block  337 . The pushing element  339  can include three pinning elements  3391  configured to mesh with the first feeding belt  200  and the second feeding belt  300  (as shown in  FIGS. 1-2 ). In at least one embodiment, the first feeding belt  200  and the second feeding belt  300  can each define a plurality of holes, and the three pinning elements  3391  can pass through the plurality of holes to mesh with and engage the first feeding belt  200  and the second feeding belt  300  (as shown in  FIGS. 1-2 ). 
     When the first feeding belt  200  and the second feeding belt  300  are transmitted to the positioning mechanism  30  (as shown in  FIG. 1 ), the pushing element  339  can push the pinning elements  3391  to engage the belts received in the receiving groove  3371 . After welding, the pushing element  339  can drive the pinning elements  3391  away from the positioning block  337 . 
       FIGS. 4-5  illustrates that the welding mechanism  40  can include a cylinder assembly  41 , a driving plate  43 , a supporting plate  45 ; a welding assembly  47 , a plurality of pressing assemblies  48 , and a plurality of cutting assemblies  49  connected to the cylinder assembly  41 . The welding mechanism  40  can be installed on the third supporting element  15 . The cylinder assembly  41  can include a first air cylinder  411 , a second air cylinder  413 , a third air cylinder  415 , and a fourth air cylinder  417 . The first air cylinder  411  can be installed on the third supporting element  15 , and the driving plate  43  can be fixed on the first air cylinder  411  thereby vertically moving with the first air cylinder  411 . The supporting plate  45  can be positioned on the driving plate  43  thereby moving with the driving plate  43 . The supporting plate  45  further include a holding plate  451 , and the pressing assembly  48  and cutting assembly  49  can be positioned on the holding plate  451 . The welding assembly  47  can be configured to weld the first feeding belt  200  and second feeding belt  300  (as shown in  FIGS. 1-2 ), and the pressing assembly  48  can be configured to flatten the welded belts. The second air cylinder  413  can be installed on the supporting plate  45  and connected to the holding plate  451 , to push the holding plate  451 , the welding assembly  47 , and the pressing assembly  48  positioned on the holding plate  451  to move horizontally with the second air cylinder  413 . 
     The cutting assembly  49  can be positioned on the supporting plate  45  and adjacent to the welding assembly  47 . The third air cylinder  415  can be located on a side of the cutting assembly  49  facing the welding assembly  47 , to push the cutting assembly  49  to horizontally move to the welding assembly  47 . The fourth air cylinder  417  can be installed on the driving plate  43  and under the cutting assembly  49 , to push the cutting assembly  49  to vertically move to the welding assembly  47  and cut off superfluous parts of the belts. 
     After the belts are engaged by the pinning elements  3391  (as shown in  FIG. 3 ), the cylinder assembly  41  can push the welding assembly  47  and the pressing assembly  48  to move to the positioning block  337  of the positioning assembly  33  which is furthest from the bracket  10  (as shown in  FIG. 1 ), to weld the belts. 
     In welding, the first air cylinder  411  drives the driving plate  43  to move and welding assembly  47  can move to face and be square with the positioning assembly  33 . Then, the second air cylinder  413  can push the welding assembly  47  to move to the positioning assembly  33  to weld the belts and transmit the welded belts after flattening by the pressing assembly  48 , to the next manufacturing process. After a welding of the belts, the second air cylinder  413  can reset the welding assembly  47  and the pressing assembly  48 . The second air cylinder  413  can push the cutting assembly  49  downward towards the welding assembly  47 , and the fourth air cylinder  417  can push the cutting assembly  49  toward the welding assembly  47  to cut off superfluous parts of the welded belts. 
     After the welding of the belts farthest from the bracket  10  (as shown in  FIG. 1 ), the feeding assembly  23  between the other two can transmit the belts to the middle positioning assembly  33 , and the cylinder assembly  41  can push the welding assembly  47  to the middle positioning assembly  33  to weld the belts. 
     After the welding of the belts transmitted by the feeding assembly  23  which is in the middle, the positioning assembly  33  nearest the bracket  10  can receive the belts from the feeding assembly  23  nearest the bracket  10  (as shown in  FIG. 1 ). The cylinder assembly  41  can push the welding assembly  47  to the positioning assembly  33  nearest the bracket  10  to weld the belts (as shown in  FIG. 1 ). 
     When welding of the belts of each feeding assembly  23  of the feeding mechanism  20  is completed, a welding process is finished and a plurality of belts can be continuously added or incorporated to be welded in a next welding process. 
     As the welding device  100  can include a control unit  50  and a feeding mechanism  20 , a positioning mechanism  30 , a welding mechanism  40  controlled by the control unit  50  (as shown in  FIG. 1 ), the welding device  100  can improve the efficiency and reduce the labor cost of the manufacturing process.
