Assembly crusher cavity

Abstract

The invention belongs to the field of online rubber recycling and crushing equipment, and in particular relates to an online recycling crusher cavity with an engineering rubber or plastic sprue. The assembly crusher cavity mainly comprises two side plates, left and right knife cavity mounting plates and a base in an enclosing mode, wherein the two side plates are respectively fixed on the base; the left and right knife cavity mounting plates are respectively movably connected with the two side plates; the inner walls of the left and right knife cavity mounting plates are respectively providedwith an arc groove; the base is provided with a knife groove transition bracket matched with the left and right knife cavity mounting plates; and when the cavity is folded, the upper surface of the knife groove transition bracket and the groove bottom surfaces of the arc grooves into a smooth arc surface. A knife groove transition mounting plate of which the upper surface is an inward concave arcsurface is additionally arranged, so that the arc grooves in the left and right knife cavity mounting plates are connected, rubber and plastic materials can more smoothly flow in the cavity, and the material blockage and material accumulation are prevented; therefore, the crushing capacity of the crusher is improved, powder is reduced and work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of rubber and plastic on-line recycling and crushing equipment, in particular to an on-line recycling and crushing machine cavity for engineering rubber or plastic gates. Background technique [0002] Existing pulverizer cavity, such as the Chinese patent application "a kind of assembled pulverizer cavity" whose application number is 200920076743.1, please refer to figure 1 , the assembled pulverizer cavity is mainly composed of two side plates, the left and right knife cavity mounting plates 1 and a base 3, and the two side plates are respectively fixed on the base 3, and the left and right knife cavity mounting plates 1 are respectively It is movably connected with the two side plates, and the inner walls of the left and right knife chamber mounting plates 1 are respectively provided with arc grooves 11 . When the left and right knife chamber mounting plates 1 are closed, the arc grooves 11 located in the left and ...

AI Technical Summary

Problems solved by technology

[0007] In this way, the following adverse consequences will be caused: when the cutter in the pulverizer rotates in the cutter groove, the groove surface of the arc cutter groove located in the left and right cutter chamber mounting plates is uneven without smooth connection, which will cause When the rubber and plastic materials reach the junction, they cannot flow smoothly, resulting in the phenomenon of accumulation

In addition, since the joint surfaces of the left and right knife chamber mounting plates are vertical, rubber and plastic materials can easily enter the joint gap under the action of gravity, and also easily form accumulations.

[0008] However, when the pulverizer is working, the knives cannot pulverize the accumulated material at the joint, so the pulverization of rubber and plastic materials will not be complete enough, which will reduce the pulverization efficiency of the pulverizer

And if the accumulation is serious, it will also cause downtime.
