[0012] The beneficial effects of the present utility model:

[0013] 1. By setting a granulator, including a fixed plastic particle collection box, a rotatable inclined plate structure is arranged in the collection box, which is convenient for discharging plastic particles of uniform size. The continuous shaft rotation is carried out through the crawler. At the same time, a flap structure is arranged at the bottom of the box body, which is convenient for taking. A plastic strip placement structure is arranged on one side of the collection box. Multiple grooves are arranged on the placement structure, which is convenient for laying and placing plastic strips. At the same time, the device can rotate. When there are finally not enough plastic particles of the same size left, the device does not granulate, rotates the overall placement device, and at the same time, the inclined plate structure rotates to limit the plastic particles from entering the bottom, so as to distinguish qualified and unqualified particles. A bracket extends from one side of the collection box for fixed support. A gear meshing rotation structure is set to rotate the pressing structure to perform rotational pressing work on the plastic strip.

A push rod structure is arranged in the middle, which expands and contracts after one granulation and scrapes it into the collection box, realizing automatic granulation work. It overcomes the disadvantages that since the lengths of plastic strips are different, the number of particles that can be cut cannot be determined. However, when the existing granulators perform granulation work, most of them directly enter all the cut particles into the same collection box. Therefore, when the length of the plastic strip is not enough to reach the required specification at the end of granulation, unqualified particles will be mixed into the collection box, thus affecting the use effect and product quality.

[0014] 2. The plastic strip is fixed and pressed, and plastic particles are restricted and collected by setting up a collection component, a restriction component, a pressing component, and a placement component. The rotation motor is started to drive the rotation shaft and the inclined plate to rotate, restricting the diameter of the incoming plastic particles. The crawler performs a shaft connection operation. The cut plastic particles that meet the specified size are collected in the collection box, and the flap facilitates the taking of plastic particles. Multiple plastic strips are laid flat on the placement groove plate, and granulation work is carried out thereon. The L-shaped support frame fixedly supports the gear motor. When the gear motor is started, it drives the gear shaft and the small gear to rotate, and the engaged large gear rotates, driving the connecting plate to rotate, so that the conveying roller fixes and presses the plastic strip. At the same time, after the first granulation is completed, the conveying motor is started to drive the conveying roller to rotate, and the plastic strip is automatically conveyed. When the last plastic strip is not large enough to meet the specified size, the rotation motor is started to drive the rotation shaft and the placement groove plate to rotate, and the remaining plastic strip is rotated and dumped. Then, granulation work is carried out through the set fixing component and granulation component.
