By setting the winding device 200, the length of the strip material determined manually is changed to be determined mechanically. The strip of paper is wound by the fixed plate 210 and the movable plate 220. After winding to a certain extent, multiple strip materials can be cut out at one time, improving the efficiency of producing strip materials. At the same time, the movable plate 220 provided can also be adjusted relative to the fixed plate 210 to adjust the length of the strip of paper attached to the winding device 200, that is, it is convenient to cut out strip materials of different lengths. It can be understood that the width of the fixed plate 210 and the width of the movable plate 220 are greater than the width of the strip material. The width of the fixed plate 210 refers to the linear dimension of the fixed plate 210 along the rotation axis direction, and the width of the movable plate 220 refers to the linear dimension of the movable plate 220 along the rotation axis direction. The strip material can be a plastic bag or a strip of paper, etc. It can be understood that the movable plate 220 can move on the fixed plate 210, that is, the movable plate 220 is adjustably connected to the fixed plate 210. One of the movable plate 220 and the fixed plate 210 is provided with a slide rail, and the other is provided with a chute. In order to lock the position of the movable plate 220 after adjustment, a first bolt is provided on the movable plate 220 or the fixed plate 210, and the first bolt is used to lock the position of the movable plate 220 on the fixed plate 210.

[0027] In some embodiments, a plurality of first connection holes 211 are provided on the fixed plate 210, and the plurality of first connection holes 211 are arranged along the width direction of the fixed plate 210. The movable plate 220 is provided with second connection holes 221, and the fixed plate 210 and the movable plate 220 are connected through the first connection holes 211 and the second connection holes 221.

[0036] In some embodiments, a wire harness box 110 is provided on the bracket 100. A plurality of ventilation openings 111 are formed in the wire harness box 110. The wire harness box 110 can bundle the cables connected to the coil material power component 600 to prevent the cables from being hung up by external objects. The provided ventilation openings 111 increase the air flow in the wire harness box 110 and prevent the outer skin of the cables in the wire harness box 110 from being oxidized due to overheating and softening for too long.

[0037] In some embodiments, both the fixing plate 210 and the movable plate 220 are made of stainless steel to prevent the fixing plate 210 and the movable plate 220 from rusting and affecting the winding of the strip material. At the same time, it also prevents the connection between the movable plate 220 and the fixing plate 210 from rusting and affecting the adjustment of the movable plate 220.
