Description

A plastic waste crushing device with compression function Technical Field

[0001] This utility model relates to the field of waste plastic crushing and recycling technology, and in particular to a plastic waste crushing device with compression function. Background Technology

[0002] A large amount of waste plastic is generated in daily life and industrial production. If this waste plastic is discarded into the environment, it will cause pollution. Therefore, people recycle waste plastic.

[0003] In the recycling and processing of waste plastics, it is often necessary to first crush them before further processing. Existing plastic crushing equipment only has a crushing function and lacks a compression function, making it impossible to compress the crushed plastic to reduce its volume, which is inconvenient for subsequent storage and transportation. Therefore, in view of the above situation, there is an urgent need to develop a plastic waste crushing device with compression function that can crush plastics while simultaneously compressing them to reduce their volume and facilitate subsequent storage and transportation, thereby overcoming the shortcomings in current practical applications and meeting current needs.

[0004] Utility Model Content

[0005] The purpose of this invention is to provide a plastic waste crushing device with compression function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A plastic waste crushing device with compression function includes a crushing box, a crushing mechanism, a compression mechanism, a transmission mechanism, a baffle, a limiting pin, and a guide plate. The crushing box has a feed inlet at its top and a discharge outlet at its bottom. The baffle for blocking the discharge outlet is detachably installed on the crushing box. The crushing mechanism is mounted on the crushing box and located directly below the feed inlet. The guide plate is fixed inside the crushing box below the crushing mechanism and is inclined downwards. The compression mechanism extends into the side of the crushing box and is located below the guide plate. The transmission mechanism for driving the crushing mechanism to rotate is mounted on the compression mechanism. The compression mechanism includes a drive motor. The system comprises a drive shaft, a half gear, an outer frame, a rack, a push-pull rod, and an extrusion plate. The drive motor is fixed to the outside of the crushing chamber. The drive shaft is rotatably connected to the outside of the crushing chamber, and the output shaft of the drive motor is fixed to the drive shaft. The half gear is fixedly mounted on the drive shaft and is located inside the outer frame. A rack, which works in conjunction with the half gear, is fixed to the upper and lower sides of the inner side of the outer frame. A push-pull rod extending into the crushing chamber is fixed to the side of the outer frame and is slidably connected to the crushing chamber. The extrusion plate is slidably installed inside the crushing chamber, and the push-pull rod is fixed to the extrusion plate. In use, waste plastic is added through the feed inlet. The compression mechanism drives the crushing mechanism to rotate, crushing the plastic. The crushed plastic slides down the guide plate while the compression mechanism extrudes it, reducing its volume. After crushing, the baffle is removed, and the plastic is taken out from the discharge outlet.

[0008] Preferably, the angle between the guide plate and the horizontal plane is 30-50°.

[0009] Preferably, the crushing mechanism includes a crushing roller and a cylindrical gear. There are two crushing rollers, both of which are rotatably connected to the crushing box. Each crushing roller is fixed with a cylindrical gear, and the two cylindrical gears mesh with each other.

[0010] Preferably, the transmission mechanism includes a drive wheel, a transmission belt, and a driven wheel. The drive wheel is fixed on the transmission shaft, and the driven wheel is fixed on the crushing roller. The drive wheel is connected to the driven wheel via the transmission belt. In use, the drive wheel is driven to rotate via the transmission shaft, which in turn drives the transmission belt and the driven wheel to rotate, and the driven wheel drives the crushing roller to rotate.

[0011] Preferably, a handle is fixed on the baffle, two plug sleeves are fixed on the baffle, and a limiting pin is slidably installed on the crushing box and inserted into the plug sleeve.

[0012] The beneficial effects of this utility model are as follows: This plastic waste crushing device with compression function allows waste plastic to be added through the inlet. A drive motor rotates the transmission shaft and half-gear, which in turn moves the rack, which in turn moves the outer frame back and forth. The outer frame then moves the push-pull rod and the extrusion plate back and forth. Simultaneously, the transmission shaft drives the drive wheel, which in turn drives the transmission belt and driven wheel, which in turn drives the crushing roller. The two crushing rollers work together to crush the waste plastic. The crushed plastic slides down the guide plate to the bottom of the crushing chamber, where the extrusion plate further compresses it, reducing its volume. After use, the limit pin is pulled out of the insertion sleeve, the handle is pulled to remove the baffle, and finally, the crushed and compressed plastic is removed from the outlet. In summary, this utility model crushes and compresses plastic simultaneously, reducing its volume and facilitating subsequent storage and transportation. Attached Figure Description
