Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, specifically a crushing device for PA9T plastic particles. Background Technology

[0002] Plastic pellets are characterized by their ease of storage and processing. In the production process of plastic pellets, they are generally extruded into strips by a screw extruder and then cut into plastic pellets after cooling. However, before the raw materials enter the screw extruder, the recycled plastic needs to be crushed to transform the large volume of plastic into small volume plastic.

[0003] Chinese patent document CN219855529U relates to the field of plastic production technology and discloses a raw material crushing device for plastic particle production. The device includes a crushing chamber containing two relatively rotating crushing rollers. Each crushing roller has a drive structure at its end for rotating. A crank is also mounted at the end of the drive structure. A connecting rod is hinged to the upper part of the crank, and a slide rail is hinged to the bottom of the connecting rod. The slide rail is slidably mounted on the outer wall of the crushing chamber, and a discharge plate is hinged to the bottom of the slide rail. The discharge plate is rotatably mounted inside the crushing chamber. In this raw material crushing device for plastic particle production, the drive unit drives the crushing rollers to rotate while simultaneously rotating the crank. Through the cooperation of the connecting rod and the slide rail, the crank allows a rotating baffle to oscillate back and forth at its rotating point, ensuring that the plastic on the discharge plate is promptly discharged from the crushing chamber, thus effectively preventing material blockage.

[0004] The existing technology has problems such as high energy consumption, low mechanical transmission efficiency and complicated equipment installation when cutting and crushing plastic particles. Therefore, it is necessary to develop a new type of crushing device for PA9T plastic particles. Utility Model Content

[0012] Preferably, the side surface of the crusher cylinder is provided with a feeding slide plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model features a conveniently assembled crusher cylinder structure. A single motor drives and controls the worm gear and worm shaft for meshing transmission, thereby synchronously driving the extrusion roller shaft and the crushing and cutting blades for rapid operation. This facilitates the extrusion and crushing of PA9T plastic particles. The crushed plastic particles are then fed through the filter screen to the crushing and cutting blades for further cutting and crushing. Finally, the fully crushed plastic particles are discharged through the discharge slide. This design offers advantages such as convenient equipment installation and control, high mechanical transmission efficiency, and simple and convenient operation. Attached Figure Description

The crushed plastic particles fall through the filter screen holes 9 on the surface of the grinding disc 8. The larger material particles remaining on the surface of the grinding disc 8 are further crushed and ground. The crushed plastic particles are fed to the crushing and cutting blades 13 through the filter screen holes 9 for further cutting and crushing. Finally, the fully crushed plastic particles can be discharged through the discharge slide plate 7.
