Description

Shredder blade

Technical Field

The utility model relates to a shredder field, concretely relates to shredder blade.

Background

With the increasing living standard, the demand of plastic products is increased, the generated plastic waste is increased in proportion, the requirement of plastic waste treatment and processing is increased, the advantage of the design in product competition is obvious, many people begin to pay attention to the design of plastic shredder products, the design of shredder blades is the most important ring in the shredder, and the blades determine the service life of the machine, the shredding effect, the yield of the machine and the maintenance cost of the machine.

Among the prior art, at shredder work in-process, the sword contact material above the shredder main shaft, inevitable wearing and tearing, wearing and tearing can influence the efficiency and the qualification rate of product, and the blade must be changed to wearing and tearing to a certain degree, and a blade is inseparable structure, will dismantle the shredder box to change the blade, increased the replacement cost.

Disclosure of Invention

In order to solve the problems, the utility model aims at providing a shredder blade increases the structure of dismantlement formula, has improved the utilization ratio of blade, and the design is rationalized more, and plastics recovery products production output and qualification rate improve, and the shredding effect has also obtained very big improvement.

For realizing above-mentioned technical purpose, reach above-mentioned technological effect, the utility model discloses a following technical scheme realizes:

a shredder blade comprises a disc-shaped shredder knife rest, a mounting hole arranged in the center of the shredder knife rest, an inner hexagon head bolt and a movable knife; the outer surface of the shredder knife rest is annularly and uniformly provided with a plurality of mounting frames, each mounting frame is internally provided with a first bolt hole, each moving knife is internally provided with a second bolt hole, each hexagon socket head bolt passes through the first bolt hole, the second bolt hole is fixed by one mounting frame and one moving knife.

Further, the mounting hole is a hexagonal hole.

Furthermore, each movable knife is quadrilateral, and each edge is provided with a cutting edge, and the total number of the cutting edges is four.

Furthermore, a spring washer is arranged at the contact position of each inner hexagon head bolt and the mounting frame.

Furthermore, the number of the mounting frames is preferably one, and each mounting frame corresponds to one movable blade.

Furthermore, one side, far away from the shredder knife rest, of the mounting rack is inclined, and the inner hexagon head bolt is a high-strength bolt.

The utility model has the advantages that:

the utility model adds the detachable structure, and improves the utilization rate of the blade greatly; the cutting edge is added, the maintenance cost of the machine is reduced, the design is more reasonable, the production yield and the qualification rate of plastic recovery products are improved, and the shredding effect is also greatly improved.

The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings. The detailed description of the present invention is given by the following examples and the accompanying drawings.
