Pulverizer knife cavity structure and corresponding pulverizer

Abstract

The invention relates to a pulverizer knife cavity structure comprising two mounting plates, two side plates and a base. A knife is arranged between the two oppositely-arranged side plates, the two oppositely-arranged mounting plates are mounted between the two side plates in a manner of being capable of opening and closing, a knife cavity is formed by the two mounting plates and the two side plates, the base is arranged at the bottom of the knife cavity, seal connection assemblies are arranged in the joint between the mounting plates and the side plates, each seal connection assembly includesat least one set of sealing face and at least one set of mounting face, and therefore pulverized bodies in the knife cavity are prevented from being leaked. The invention also provides a corresponding pulverizer. The pulverizer knife cavity structure and the corresponding pulverizer are adopted, the seal connection assemblies are arranged, sealing of the knife cavity of the pulverizer is achieved, opening and closing of the mounting plates are not affected, and powder leakage during pulverization is prevented; the number of times of cleaning is reduced, the working time is shortened, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of pulverization, in particular to a pulverizer knife chamber structure and a corresponding pulverizer. Background technique [0002] In the injection process of rubber or injection molded parts, the nozzle material is generally recycled. When the nozzle material is recycled, it is usually processed by crushing and dust removal before being reused. Such as figure 1 As shown, the existing pulverizer is generally connected by 5 knife chamber plates, side plates 1, 2, mounting plates 3, 4, base, and a knife 5 is installed in the knife chamber, in order to ensure the opening and closing of the mounting plate to facilitate cleaning , A certain gap must be ensured between the mounting plates 3, 4 and the side plates 1, 2, and this gap often leads to leakage of nozzle material powder, which will affect the environment of the injection molding workshop and easily cause mixing. [0003] In addition, the pulverizer ...

Problems solved by technology

like figure 1 As shown, the existing pulverizer is generally connected by 5 knife chamber plates, side plates 1, 2, mounting plates 3, 4, base, and a knife 5 is installed in the knife chamber, in order to ensure the opening and closing of the mounting plate to facilitate cleaning , A certain gap must be ensured between the mounting plates 3, 4 and the side plates 1, 2, and this gap often leads to leakage of nozzle material powder, which will affect the environment of the injection molding workshop and easily cause mixing.

[0003] In addition, the pulverizer is generally connected with the feeding hopper. Since the pulverizer often needs to be opened for cleaning, the connection between the feeding hopper and the knife chamber of the pulverizer is usually designed to be opened quickly, but the lower connection surface of the feeding hopper is connected to the knife chamber. There is often powder leakage on the surface, and the connection is usually a flat seal. Due to frequent opening and closing, the plane will be deformed after long-term use and there will be gaps, which will easily spill powder and affect the site environment.
