Refer to <FIG>, the column mechanism provided by the present invention is a part of the winding machine, and comprises a column <NUM>, a base <NUM> and a turntable <NUM>. The column <NUM> comprises a column frame <NUM>.

The column frame can be assembled by metal parts with certain rigidity and strength which can bear the weight. The column also comprises a plurality of column panels, at least a part of which is detachable and connected with the column frame. During transportation, there is a way that these panels can be removed from the column frame <NUM> and packaged properly, so they will not be damaged during transportation. However, in the use site, the column assembly can be completed by simply attaching to the column frame <NUM>, without complex column assembling work. Even if the panel is not disassembled during transportation, in case of collision, it is only a partial replacement of the panel, which will not cause the whole column to be scrapped and save the cost.

As for the column frame, it is not easy to be knocked to damage the appearance, even if it is knocked, it is not easy to deform. If the winding machine removes the panel for transportation, even if the column frame has partial appearance damage, it has little or no impact on the column shape.

Further, the column frame <NUM> itself is a unit structure, which forms a whole and is suitable for hinged connection with the base. In this way, the column frame <NUM> can be pre-installed on the base <NUM> in the same way as the previous column in the form of rotatable connection, which is convenient for transportation and more convenient for field installation.

The rotatable connection position of the column frame can be at the bottom of the side facing the turntable <NUM> and hinged through the tubular member <NUM> and the horizontal pin <NUM> on the base.

For the column panels, all column panels can be detachably connected with the column frame. Even so, it is not necessary to remove some panels that are not easy to be bumped or will be covered by some winding machine parts during transportation (these panels do not have to be detachably connected with the column frame), for example, the panel <NUM> at the lower part of the column facing the turntable can be connected to the column framework <NUM> when shipped from the factory. For another example, the panel that will be covered by the lifting film frame <NUM> does not have to be removed.

The detachable connection can be various mechanical connection structures such as screw, buckle connection, clamping connection, pin connection, etc..

The column panels detachably connected with the column frame includes an electric control door <NUM>, which is equipped with buttons, indicator lights, etc. Generally, some electrical devices are installed on the back of the electric control door, and the electric control door <NUM> can be rotatably connected with the column frame through pins <NUM>.

The column panels detachably connected with the column frame comprises an access door <NUM>, and the access door <NUM> is detachably connected with the column frame <NUM> by adopting an inclined slot <NUM> and a transverse bolt <NUM> matching structure, which is convenient for opening and closing, and has no interference during maintenance.

If the locks are required for the doors <NUM> and <NUM>, the locks of the conventional structure can be directly locked on the column frame <NUM>.

The top cover <NUM> of the column is connected with the column frame <NUM>, and the connection mode can also adopt screw connection.

The lifting mechanism <NUM> of the winding machine's lifting film frame <NUM> is connected with the column frame. Compared with the past, the lifting mechanism is not easy to deform and deviate from the position, and the lifting work is more stable.

The reference numbers <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM> and <NUM> are the panels of the column which can be disassembled and connected with the column frame according to the needs.

As shown in <FIG>, for the column shape with four inclined angles, for those column panels that need to be turned and opened, such as electric control door 803b, doors 824b and 825b above and below the electric control door, they can be detachably connected with the adjacent column panels at the inclined angle through hinge <NUM>. In <FIG> and <FIG>, the reference numbers are the same as those in <FIG>, and represents the same meaning.
