Assembly type crushing roller and wood pulp crusher

Abstract

The invention relates to the field of disposable hygienic product equipment, in particular to an assembly type crushing roller and wood pulp crusher which comprises a machine frame, a crushing mechanism, a crushing roller, an upper knife edge plate assembly, a lower knife edge plate assembly and an input production line, a knife edge plate is detachably arranged in the lower knife edge plate assembly, blade blocks are arranged on one side of the knife edge plate, wherein the blade blocks are installed on a first protruding part, a second protruding part, a third protruding part and a fourth protruding part, the two blade blocks can be directly installed on the first protruding part, and the situation that customized blade blocks need to be purchased additionally, and the use cost is increased is avoided. The blade blocks are good in hardness and abrasion resistance, the defect that an operator needs to replace the crushing roller due to the fact that the crushing roller is prone to abrasion and blunt blades is overcome, meanwhile, the knife edge plate can be protected, high replacement cost after the knife edge plate is damaged is avoided, and the problems that under the impact force of a tooth roller, the blunt blades are prone to being abraded in an accelerated mode, and therefore, the operator needs to frequently replace and maintain a crushing area are solved.

Description

technical field [0001] The invention relates to the field of disposable hygiene products, in particular to an assembled crushing roller and a wood pulp grinder. Background technique [0002] At present, the Chinese patent application number: CN200710109447.2 discloses a wood pulp pulverizer, which includes a shell, toothed rollers, and a combined fixed knife block. The combined fixed knife block includes a lower fence, and a secondary output groove is provided on the lower fence. The secondary output chute is connected to the crushing cavity of the wood pulp grinder. During the process of the pulverizer crushing the wood pulp board, the secondary output trough can export the crushed material remaining in the crushing cavity, although it has the function of reducing the crushed material in the crushing cavity. The benefits of the probability of retention and agglomeration; but when the crushing area, the initial area of ​​the separation of the crushed matter, and the separati...
