Crushing mechanism of plastic crusher

Abstract

The invention relates to a crushing mechanism of a plastic crusher, which comprises a transmission shaft, a fixed cutter and a movable cutter set, wherein the movable cutter set comprises a plurality of press cutters and circular cutters, the press cutters and the circular cutters are arranged on the transmission shaft through concentric shaft holes, and two sides of the movable cutter set are provided with a group of fixed cutters respectively; the movable cutter set comprises three press cutters and four circular cutters, wherein the press cutters form a three-leaf spiral structure and each press cutter is provided with three R-shaped press cutter edges, and a plurality of blades of the circular cutters are regularly arranged to form a spiral V-shaped structure and each circular cutter is provided with a plurality of R-shaped circular cutter edges; and a fixed cutter edge matched with the movable cutter part is formed inside the fixed cutter. The crushing mechanism of the plastic crusher has the advantages that through the R-shaped edges formed on the edges of the press cutters and the circular cutters respectively, the irregular cut materials are ensured, the production of dust is reduced, and the conventional complex structure is simplified; and meanwhile, the traditional screen is replaced by adopting the fixed cutter structure, so the assembly is convenient to mount and maintain.

Description

technical field

[0001] The invention relates to a plastic crushing mechanical device, in particular to a crushing mechanism of a plastic crusher. Background technique

[0002] The plastic crusher is mainly used to crush various plastic plastics or rubber such as plastic profiles, pipes, rods, silk threads, films, and waste rubber products. The plastic crusher is an ideal equipment for recycling large profiles. It has large crushing capacity, high output, and stable working performance. It is equipped with an automatic suction machine, which improves the machine. When the injection molding machine or granulator produces raw materials, the defective products and outlet materials produced can be put into the machine in time. After crushing, the side plastic crusher should be kept clean and dry; the plastic crusher can be combined with other auxiliary machines (such as dryers, dehumidifiers, chillers, etc.) to form a crushing and recycling system that can improve product quality...
