[0039] Working principle: after the consumables are wound on the surface of the winding disc 213, the driving motor 206 drives the main shaft 207 and the reciprocating screw rod 303 to rotate, the main shaft 207 can drive the winding disc 213 to rotate synchronously through the cooperation of the clamping block 215 and the clamping groove, so that the consumables can be wound, and the movable table 304 can move on the surface of the reciprocating screw rod 303, so that the consumables can be wound more uniformly on the surface of the winding disc 213. Before winding, the height position of the mounting plate 204 can be controlled through the first cylinder 203, so that the photoelectric sensor 205 can be moved to the expected consumable limiting thickness position. During the winding process, the thickness of the consumables on the surface of the winding disc 213 increases gradually, when the thickness of the consumables increases to block the laser rays emitted by the photoelectric sensor 205 on both sides, it means that the winding thickness of the consumables on the surface of the winding disc 213 reaches the thickness requirement. At this time, the photoelectric sensor 205 will transmit a signal to the controller 208, and the controller 208 will control the driving motor 206 and the electric push rod 102, so that the driving motor 206 stops rotating the main shaft 207, and the electric push rod 102 drives the cutting knife 104 to move downward, completing the cutting of the consumables. In this way, the automatic cutting effect after the thickness reaches the requirement is realized, the thickness accuracy of the consumables is improved during each winding, and then the second cylinder 210 can be adjusted, so that the second cylinder 210 retracts. At this time, the movable block 211 drives the clamping block 215 on one side to be taken out from the clamping groove, so that the winding disc 213 after winding can be taken out from one side of the main shaft 207.

[0040] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
