[0045] It should be noted that the shape of the collecting hopper 5 can be conical or square.

[0046] Working principle: When in use, first pull the support rod 204 to one side to rotate in the telescopic cylinder 202 and compress the spring 207 at the same time, the support rod 204 drives the cutting knife 206 and the roller 205 to move, and then the chip with the protective film is placed on the first clamping plate 401, and then the threaded screw 303 is turned to rotate on the support frame 301, and the threaded screw 303 drives the fixing plate 304 to slide downward on the second limiting groove 302 through the threaded connection. When the fixing plate 304 drives one end of the second clamping plate 402 to fit on the chip, the chip is clamped and fixed by the action of the first clamping plate 401, thereby preventing the subsequent chip from being damaged due to displacement when the protective film is rotated and cut. Then, the support rod 204 is released at a uniform speed, and the roller 205 is fit to the edge of the chip through the rebound action of the spring 207, and then the motor 403 is turned on, and the motor 403 drives the first bevel gear 404 to rotate, and the second A bevel gear 404 drives the second bevel gear 405 to rotate, and the second bevel gear 405 drives the second clamping plate 402 to rotate on the fixed plate 304. At the same time, the chip is driven to rotate at a uniform speed by the rotation of the first clamping plate 401 on the support platform 406. The cutting knife 206 cuts the protective film on the edge of the chip through the contact of the roller 205. When cutting chips of different shapes, the cutting knife 206 cuts along the edge of the chip shape through the reciprocating compression of the spring 207 and the rebound of the spring 207, thereby improving the accuracy of the chip protective film. The cutting knife 206 is a double-sided blade. The staff can further improve the cutting efficiency of the chip by turning on the motor 403 forward and backward to cooperate with the double-sided blade of the cutting knife 206. The waste chip protective film after cutting falls into the collection bucket 5, and falls into the collection container through the collection bucket 5, which is convenient for the staff to collect later.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
