[0031] A plastic packaging box fixing component 5 is provided on the top of the rotating disc 203. Since the plastic packaging box fixing component 5 is provided on the top of the position adjustment component 2, it is convenient to fix the plastic packaging box on the rotating disc 203, and the rotating disc 203 is driven by the double-headed motor 202 to rotate, thereby driving the rotating disc 203 to rotate, and driving the plastic packaging box on the rotating disc 203 to rotate, so as to adjust the position of the plastic packaging box and facilitate cutting the waste edge of the plastic packaging box.

[0032] In this embodiment, the waste edge cleaning component 3 includes a rotating plate 301, a connecting column 302, a square frame 303, a first limiting plate 304, a movable plate 305, a horizontal plate 306, a connecting rod 307 and a scraper 308. The output shaft at the bottom of the double-headed motor 202 is fixedly installed with the rotating plate 301, the front side of the bottom of the rotating plate 301 is fixedly installed with the connecting column 302, the outer side of the connecting column 302 is movably sleeved with the square frame 303, the bottom of the connecting column 302 is fixedly installed with the first limiting plate 304, the two sides of the square frame 303 are fixedly installed with the movable plate 305, the outer side of the movable plate 305 is movably sleeved on the lower part of the first support frame 201, one side of one of the movable plates 305 is fixedly installed with a horizontal plate 306, one side of the horizontal plate 306 is fixedly installed with a connecting rod 307, and a scraper 308 is provided at one end of the connecting rod 307. The double-headed motor 202 can drive the rotating plate 301 to rotate. Since the rotating plate 301 is connected to the first limit plate 304 and the square frame 303, the movable plate 305 is driven to reciprocate along the lower part of the first support frame 201. Since the movable plate 305 is provided with a connecting rod 307 and a scraper 308, it is convenient to drive the scraper 308 to move back and forth, so that the cut waste edges can be collected on both sides of the top of the bottom plate 1, which is convenient for subsequent collection.

[0033] In this embodiment, the square frame 303 and the movable plate 305 are vertically arranged, and the top of the first limiting plate 304 is in contact with the bottom of the square frame 303. The square frame 303 and the movable plate 305 are vertically arranged, and the top of the first limiting plate 304 is in contact with the bottom of the square frame 303, so that the square frame 303 can drive the movable plate 305 to reciprocate horizontally through the rotation of the rotating plate 301 and the connecting column 302.

[0034] In this embodiment, the connecting rod 307 is located at the rear side of the rotating disc 203, and the bottom of the scraper 308 is in contact with the top of the bottom plate 1. Since the connecting rod 307 is located at the rear side of the rotating disc 203, the bottom of the scraper 308 is in contact with the top of the bottom plate 1, so that the waste edges falling on the top of the bottom plate 1 can be collected and stacked, and the waste edges can be processed later.

[0035] In this embodiment, the positioning and cutting assembly 4 includes a lifting cylinder 401, a mounting seat 402, a positioning plate 403, a three-section cylinder 404 and a cutting knife 405. The lifting cylinder 401 is fixedly installed on one side of the top rear side of the bottom plate 1, the mounting seat 402 is fixedly installed on the output end of the lifting cylinder 401, the positioning plate 403 is fixedly installed on the side of the mounting seat 402 close to the rotating disc 203, the three-section cylinder 404 is fixedly installed on the top of the mounting seat 402, and the cutting knife 405 is fixedly installed on the output end of the three-section cylinder 404. The positioning and cutting assembly 4 is arranged on the top of the bottom plate 1, and the positioning plate 403 and the cutting knife 405 can be driven to move to different heights by the lifting cylinder 401, so as to facilitate the cutting of waste edges at different heights, thereby improving the practicality of the device.

[0036] In this embodiment, the cutting blade 405 is located above the positioning plate 403 , and the positioning plate 403 is located at the rear side of the rotating disk 203 .

[0037] In this embodiment, the plastic packaging box fixing assembly 5 includes an electromagnet 501, a second support frame 502, a guide rod 503, a second limit plate 504 and a fixed iron plate 505. The second support frame 502 is fixedly installed on one side of the top of the bottom plate 1, and the electromagnet 501 is fixedly installed at the top center of the rotating disc 203. The guide rod 503 is movably sleeved on one side of the second support frame 502, and the second limit plate 504 is fixedly installed on the top of the guide rod 503. The fixed iron plate 505 is fixedly installed on the bottom of the guide rod 503. The plastic packaging box fixing assembly 5 is provided above the rotating disc 203, and the plastic packaging box is placed between the electromagnet 501 and the fixed iron plate 505. The electromagnet 501 is energized, and the electromagnet 501 generates a magnetic force to adsorb the fixed iron plate 505, so that the plastic packaging box is clamped between the fixed iron plate 505 and the electromagnet 501, and the plastic packaging box to be cut is fixed, which improves the stability of the waste edge of the plastic packaging box.

[0038] In this embodiment, the fixed iron plate 505 is located directly above the electromagnet 501, and the second support frame 502 is in an L-shape. By the fixed iron plate 505 being located directly above the electromagnet 501, the second support frame 502 is in an L-shape, which is convenient for supporting the guide rod 503 and the fixed iron plate 505.

[0039] Working principle: When using this device, the positioning plate 403 is adjusted to a suitable height through the operation of the lifting cylinder 401;

[0040] The plastic packaging box that needs to have its scrap edges cut off is placed on the top of the electromagnet 501 and the rotating disc 203, so that one side of the plastic packaging box that needs to have its scrap edges cut off is in contact with the positioning plate 403. After the electromagnet 501 is energized, a magnetic force is generated to adsorb the fixed iron plate 505, and the plastic packaging box that needs to have its scrap edges cut off is fixed between the electromagnet 501 and the fixed iron plate 505.

[0041] The three-section cylinder 404 is driven to drive the cutting knife 405 to move, and the waste edge of the plastic packaging box that needs to be cut off is cut off. After the outer wall is cut off, the three-section cylinder 404 is driven to drive the cutting knife 405 to retract, and then the double-headed motor 202 is driven to drive the rotating disk 203 to rotate ninety degrees and then stop running, and the other side of the plastic packaging box is rotated to a position in contact with the positioning plate 403, and then the three-section cylinder 404 and the cutting knife 405 are used for cutting;

[0042] At this time, the double-headed motor 202 drives the rotating plate 301 to rotate ninety degrees. Since the rotating plate 301 is connected to the square frame 303 by the connecting column 302 and the first limiting plate 304, and is connected between the moving plate 305 on the square frame 303 and the first supporting frame 201, the connecting rod 307 and the scraper 308 are driven to move toward one side of the top of the bottom plate 1 to stack the cut waste edges.

[0043] By starting the double-headed motor 202 to rotate ninety degrees each time, the four sides of the plastic packaging box can be cut.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
