Plastic grinder

Abstract

The invention relates to a grinder, in particular to a plastic grinder. The plastic grinder comprises a grinder body, a moving cutter, a fixed cutter and a screen plate, wherein the moving cutter and the fixed cutter are arranged inside the grinder body; the screen plate is arranged below the moving cutter and the fixed cutter; a shifting wheel cutter is mounted inside the grinder body and in a position above the moving cutter and the fixed cutter, the rotation direction of the shifting wheel cutter is opposite to that of the moving cutter, and the shifting wheel cutter is rotationally occluded with the moving cutter; the grinder body adopts a closed box body structure; a feed inlet with a material splashing prevention device is formed in the upper part of the grinder body; a discharge opening matched with the bag mouth of a packaging bag is formed in the lower part of the grinder body. The plastic grinder solves the problems that a conventional grinder has low working efficiency at a low rotating speed, when the conventional grinder operates at a high rotating speed, ground raw materials fly up under the action of the centrifugal force of the ground materials and a moving cutter and a fixed cutter cannot sufficiently occlude the ground materials so as to waste power. The plastic grinder has high working efficiency; a conventional grinder with the same power only grinds 1 ton of plastics each hour, but the plastic grinder can grind 3 tons of plastics each hour; the plastic grinder adopts the closed structure, so that the phenomenon that dust flies out in the working process of the plastic mill is avoided, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a plastic pulverizer. Background technique [0002] Existing plastic pulverizers only rely on the cooperation of the moving knife and the fixed knife to pulverize plastic, and the work efficiency is low, and the pulverization of plastic is less than one ton per hour; The splash in the middle is more serious, almost dusty, which not only wastes raw materials, but also pollutes the environment. Contents of the invention [0003] The problem to be solved by the present invention is to provide a plastic pulverizer with high crushing efficiency, reduced dust flying out, and reduced environmental pollution. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A plastic pulverizer, comprising a body, a moving knife and a fixed knife installed inside the body, a sieve plate installed below the moving knife and...
