There are several convex rods 2522 and support spring 2 2525, and several convex rods 2522 are installed on the movable long knife 2520. By installing multiple convex rods 2522 on the movable long knife 2520, the movable long knife 2520 is more stable during operation, and no breakage or bending will occur when shearing plastic, thereby improving the stability of the device.

By rotating the threaded rod 264, the threaded rod 264 can move toward the fixing block 261 during rotation, so that the threaded rod 264 can be inserted into the fixing hole 262 on the fixing block 261. At this time, the rotating cylinder 2513 cannot rotate, so that the adjusting rod 2527 can rotate.

[0044] In a preferred embodiment, a vertical pole bracket 267 is fixedly mounted on the top of the fixed block 261, and a support spring 3 2610 is movably sleeved on the outer edge of the vertical pole bracket 267. The support spring 3 2610 supports the horizontal plate 268, so that the latch 2681 can be stably inserted into the adjustment hole 1 265, and the latch 2681 contacts the adjustment rod 2527, so that the adjustment rod 2527 can rotate synchronously with the rotating cylinder 2513, so that the rotating cylinder 2513 will not cause the adjustment rod 2527 to move when rotating, thereby improving the stability of the device. The outer edge of the adjustment rod 2527 is provided with an adjustment hole 1 265 and an adjustment hole 266, and the outer edge of the vertical pole bracket 267 is movably connected with a horizontal plate 268.

When the pin 2681 is inserted into the adjusting hole 266, the device is in a state of crushing hard plastic. The top of the horizontal plate 268 is fixedly equipped with a pull rod 269. The outer edge of the pull rod 269 is movably sleeved with a support block 2611. By pulling the pull rod 269, the horizontal plate 268 and the pin 2681 are driven to move upward. Then, the support block 2611 is brought into contact with the vertical pole bracket 267, so that the horizontal plate 268 and the pin 2681 cannot move downward, and the threaded rod 264 is convenient to rotate.

[0045] Working principle: when in use, the bottom turntable 2533 is driven to rotate by driving the servo motor 2534, and the rotation of the bottom turntable 2533 drives the belt 2532 to rotate, and the rotation of the belt 2532 drives the top turntable 2531 to rotate, so that the rotating cylinder 2513, the concave rod 2518, the movable cutting knife 2519, the convex strip 2523, and the movable long knife 2520 rotate. At this time, the movable cutting knife 2519 and the fixed cutting knife 255 shear each other, and the movable cutting knife 2519 and the fixed cutting knife 255 break the plastic film. When it is necessary to adjust the hard plastic, at this time, by rotating the adjusting rod 2527 60°, the convex rod 2522 is located at the convex position of the long knife adjusting triangle block 2528, and the concave rod 2518 changes from the convex position of the cutting knife adjusting triangle block 2529 to the convex position of the cutting knife adjusting triangle block 2528. The cutter adjusts the depression of the triangular block 2529, and the crushing mode is changed. At this time, the movable long knife 2520 on the convex rod 2522 is tangent to the fixed long knife 2511, and then the rotating cylinder 2513, the concave rod 2518, the movable cutting knife 2519, the convex strip 2523, and the movable long knife 2520 are rotated to cut the hard plastic. When crushing the plastic, the lifting servo motor 258 is operated, and the lifting servo motor 258 drives the screw rod 257 to rotate. The rotation of the screw rod 257 drives the connecting plate 256 to rise. The connecting plate 256 rises and drives the connecting rod 252, the connecting block 253 and the fixed cutting knife 255 to slide in the limiting track 251, and the plastic film on the connecting block 253 can fall into the discharge port 24 for discharge, and the crushed hard plastic can fall into the discharge port 24 through the through hole 254 on the connecting block 253 and be discharged.
