Description

A waste plastic shredding device

technical field

The utility model belongs to the technical field of plastic production equipment, in particular to a waste plastic crushing device.

Background technique

At present, most of the plastic recycling process requires the use of crushers, and the recycled plastics must be put into the crusher to be broken into small particles before further processing. A traditional crusher generally includes a crusher working room, a crushing motor knife installed at the bottom of the crusher working room, a fixed knife set opposite to the crusher machine knife, a feeding port set on the upper part of the crusher working room, and a crusher located under the crusher knife. The discharge mesh plate. During the crushing process of traditional crushers, blocky plastics will roll up and down in the crusher working chamber, staying for a long time, and cannot be crushed into small particles quickly. The crushing efficiency is low, which seriously affects the output. At the same time, due to the large volume of some waste plastics, they are relatively difficult to crush, and they will move up and down in the crusher box, affecting the crushing efficiency and causing wear to the box. Moreover, the crushing speed is different for different sizes of plastics, and it is difficult to feed materials. Control the feeding speed. If the feed is too large at one time, it will accumulate on the top of the cutter, which will affect the operation of the cutter and damage the cutter. In addition, large dust will be generated during crushing, which will harm the health of the staff when it is released into the air.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model provides a waste plastic crushing device. The crushing device can crush waste plastics into fine particles at one time through the combination of cutter and rolling, which greatly improves the crushing efficiency of waste plastics.

In order to realize the above technical solution, the utility model provides a waste plastic crushing device, comprising: a screw feeder; a feeding hopper installed at the inlet of the screw feeder; a hopper installed at the outlet of the screw feeder The crushing roller, on which the cutters are evenly installed in a circular array; the first filter screen arranged under the crushing roller; the first receiving chute installed under the first filter screen; installed in the first The discharge pipe at the end of the filter screen; the first rolling roller and the second rolling roller installed directly below the outlet of the discharging pipe and symmetrically arranged left and right; installed on the first rolling roller and the second rolling roller The second filter screen below; the second receiving tank installed under the second filter screen; and the waste material tank arranged at the end of the second filter screen.

In the above technical scheme, large pieces of waste plastics enter the screw feeder from the hopper, and the screw feeder will initially damage the waste plastics. When the waste plastics run to the outlet of the screw feeder, The rotating crushing roller cuts the waste plastic through the cutter installed on the roller, and some of the plastic can be cut into small particles, and then enter the first receiving trough through the first filter screen for collection, and after cutting but not Large pieces of waste plastics that can pass through the first filter screen enter the gap between the first rolling roller and the second rolling roller through the discharge pipe installed at the end of the first filtering screen, and pass through the first rolling roller and the second rolling roller. The second rolling roller grinds and grinds the cut waste plastics, and the plastic particles that have been rolled and ground are finally filtered by the second filter screen and then enter the second receiving tank, while the impurities that cannot be broken finally pass through the discharge The feed port enters the waste trough. In this way, through the double cooperation of the crushing roller and the rolling roller, the waste plastic can be crushed into fine particles at one time, which greatly improves the crushing efficiency of the waste plastic.

Preferably, a first vibrator is installed on the first filter, and a second vibrator is installed on the second filter. The vibrator is used to maintain the continuous vibration of the filter screen, and strengthen the vibration frequency of the small plastic particles on the filter screen, so that the small particles can be filtered from the filter screen, and the vibration can also push the large plastic particles that cannot pass through the filter screen slowly towards the discharge port. direction to move.

Preferably, a baffle plate is arranged obliquely above the discharge pipe. The function of the material baffle is to guide the plastic particles that cannot pass through the first filter screen to be discharged from the discharge pipe.

Preferably, the screw feeder is a twin-screw extrusion feeder. Through the twin-screw extrusion feeder, some large pieces of plastic can be initially crushed and crushed to improve the efficiency of subsequent plastic crushing.

The beneficial effect of the waste plastic crushing device provided by the utility model is that the waste plastic crushing device continuously crushes waste plastics in the form of extruding, cutting and rolling, and can crush waste plastics at one time. into fine particles, greatly improving the crushing efficiency of waste plastics, and filtering through multiple filters at the same time to ensure the quality of plastic crushing.
