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

A kind of crushing mechanism of plastic breaker

Technical field

The present invention relates to a kind of plastic breaker tool equipment, relate in particular to a kind of crushing mechanism of plastic breaker.

Background technology

Plastic breaker is mainly used in broken various thermoplastic plastic or rubber such as plastic irregular profile, pipe, rod, silk thread, film, waste rubber goods, and plastic breaker is the ideal equipment that reclaims heavy section.Had that breaking capacity is big, output is high, stable work in work, and be equipped with automatic Material sucking machine, improved this machine, in injection machine or comminutor raw materials for production, the defective products of generation and mouth of a river material, can in time drop into machine limit plastic breaker through after pulverizing, and keep the clean, dry of pulverizing; Plastic breaker can cooperate the pulverizing recovery system that forms with other subsidiary engines (as drying machine, dehumidifier, cooling-water machine etc.), can improve the quality of product; The crushing mechanism design of tradition disintegrating machine is reasonable inadequately, and its broken cutter tooth adopts the right-angle structure design, exists deficiencies such as blank is irregular, powder is many, complex structure; In addition, installation and maintenance inconvenience under many circumstances, the mechanical carrier load is big simultaneously.

Summary of the invention

At above defective, the invention provides a kind of crushing mechanism of plastic breaker, the prior art blank is irregular, powder is many to solve, the defective of complex structure, installation and maintenance inconvenience.

For achieving the above object, the present invention is by the following technical solutions:

A kind of crushing mechanism of plastic breaker comprises by power transmission shaft, stationary knife and movable cutter set constituting, and described movable cutter set comprises some push type broach and dise knife composition, and described push type broach is installed on the power transmission shaft by concentric axis hole with dise knife, and the movable cutter set both sides are provided with one group of stationary knife respectively; Described movable cutter set comprises by three push type broach and four dise knifes and forming, described push type broach is that tri-lobed helical structure and each push type broach are provided with three R shape push type broach edges of a knife, and some blade overall alignment of described dise knife are that spiral V font structure and each dise knife are provided with some R shape dise knife edges of a knife; Described stationary knife inboard is provided with the stationary knife edge of a knife that partly is complementary with moving knife.

The beneficial effect of the crushing mechanism of plastic breaker of the present invention is: by on the push type broach and the dise knife edge of a knife, offering the R edge of a knife respectively, with guarantee that blank is neat, reduce powder generation, simplified complicated in the past structure; Adopt the stationary knife structure to substitute traditional screen cloth simultaneously, the assembly installation and maintenance are convenient.

The specific embodiment

Shown in Fig. 1-6, the crushing mechanism of the described plastic breaker of the embodiment of the invention, comprise by power transmission shaft 1, stationary knife 2 and movable cutter set and constituting, described movable cutter set comprises three identical push type broach 3 and four dise knifes 4 compositions, described push type broach 3 and the center of dise knife 4 are all offered concentric push type broach axis hole 7 and dise knife axis hole 8 and are installed on the power transmission shaft 1 by axis hole, and described push type broach 3 is provided with three R shape push type broach edges of a knife 6 for tri-lobed helical structure and each push type broach 3; Some blade overall alignment of described dise knife 4 are that spiral V font structure and each dise knife 4 are provided with some R shape dise knife edges of a knife 9, and the movable cutter set both sides are provided with one group of stationary knife 2 respectively and are provided with the stationary knife edge of a knife 5 that partly is complementary with moving knife.This crushing mechanism is installed on the body 10 of disintegrating machine, during work, push type broach 3 utilizes its R shape push type broach edge of a knife 6 that the plastics of bulk are broken earlier, every independent stressed, be broken into graininess with the some R shape dise knife edges of a knife 9 on four sections dise knifes 4 again, by with the stationary knife edge of a knife 5 places discharging that leaves certain slit of stationary knife 2 coupling.

Above embodiment is the more preferably specific embodiment a kind of of the present invention, the common variation that those skilled in the art carry out in the technical program scope and replace and should be included in protection scope of the present invention.
