The anti-wrinkle mechanism includes a plurality of limiting rollers rotatably arranged on the front and rear sides of the frame, and a limiting plate is detachably provided on the upper part of the frame below the plurality of limiting rollers, and the distance between the upper part of the limiting plate and the limiting roller is greater than the thickness of the workpiece to be cut.

[0006] The distance between the upper part of the limiting plate and the limiting roller is greater than 0.5-1.5 mm of the thickness of the workpiece to be cut.

[0007] The cutting mechanism includes a motor arranged at the lower part of the frame, a rotating shaft is provided at the end of the output shaft of the motor, a driving sprocket is clamped on the rotating shaft, a crank-connecting rod assembly is provided on the upper chain transmission of the driving sprocket, a cutter is provided on the upper part of the connecting rod of the crank-connecting rod assembly, a slider is provided on the back of the cutter, a vertical rod is provided on the frame, a slide rail is provided on the vertical rod, and the slider is slidably arranged on the slide rail.

[0008] The pushing mechanism comprises an active roller connected to the active sprocket through a chain transmission, and a pushing roller is rotatably arranged below the active roller and on the frame.

[0009] The limiting plate is L-shaped, and the inner side wall of the horizontal portion of the limiting plate is fitted with the upper portion of the frame, and the inner side wall of the vertical portion of the limiting plate is fitted with the outer side wall of the vertical portion of the frame.

[0010] A baffle is provided on the outer side of the limiting plate, a locking bolt is threadedly connected to the baffle, and a threaded hole adapted to the locking bolt is opened on the frame.

[0011] A handle is provided on the outer side wall of the baffle.

[0012] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects:

[0013] 1. The utility model can realize the limitation and guidance of the insulating paper passing through the anti-wrinkle mechanism through the cooperation of the limiting roller and the limiting plate in the cutting mechanism during the cutting process of the insulating paper, thereby avoiding the occurrence of curling and wrinkles.

[0030] The use method of this utility model:

[0031] First of all, it should be clear that the cutting device involved in the present invention is mainly used for cutting thin plates or insulating paper. The present invention takes the cutting of insulating paper as an example to explain its method of use in detail. When it is necessary to cut the insulating paper, first select a limit plate 420 of appropriate thickness according to the thickness of the insulating paper. Then the operator grasps the handle 450 and buckles the limit plate 420 on the frame 100. Then, the locking bolt 440 is screwed into the frame 100. Then, the operator passes the cut insulating paper through the bottom of the cutter 240, between the active roller 310 and the push roller 320, and between the limit roller 410 and the limit plate 420 in turn. Then, the end of the insulating paper is glued to the winder and the winder is started for winding. After the winding is completed, the output shaft of the motor 210 is started to rotate, and the output shaft of the motor 210 is rotated to drive the rotating shaft and The driving sprocket 220 rotates together, and the guide rail 270 has a guiding and limiting effect on the slider 250, and the vertical rod 260 has a supporting and fixing effect on the slide rail 270. The rotation of the driving sprocket 220 can drive the connecting rod of the crank connecting rod assembly 230 to carry the cutter 240 and the slider 250 to move up and down along the slide rail 270 through chain transmission, thereby realizing the cutting operation of the cutting piece. Due to the action of the anti-wrinkle mechanism 400, when the insulating paper passes through the cutting mechanism 200 and the pushing mechanism 300 to cut the insulating paper, the limiting roller 410 and the limiting plate 420 in the anti-wrinkle mechanism 400 cooperate to limit and guide the insulating paper passing between the two, thereby avoiding curling and wrinkling. There is no need for the operator to perform subsequent flattening operations, which greatly improves the cutting efficiency of the insulating paper.
