Plastic particle pulverizer with knife blade edge angle adjustable function

Abstract

The invention discloses a plastic particle pulverizer with a knife blade edge angle adjustable function. The pulverizer structurally comprises a plastic particle pulverizing device, a pulverizer body,a material storage box, full-braking trundles and a pulverizing bin. The full-braking trundles are mechanically connected to the four corners of the bottom surface of the pulverizer body correspondingly. The material storage box is arranged under the pulverizer body. Compared with the prior art, the plastic particle pulverizer has the beneficial effects that the angle adjustable function is achieved, a turnplate indirectly makes supporting shafts revolve on the axes of the supporting shafts so as to drive a plurality of pulverizing blades to synchronously rotate, accordingly, the purpose thatthe pulverizing blade edge angles are adjusted is achieved, the blade edge angles can be adjusted to be small when soft plastic is pulverized, the soft plastic can be pulverized into smaller particles easily by means of the pulverizing blades, the blade edge angles can also be adjusted to be big when hard plastic is pulverized, the situation that the blade edge angles are too sharp, and consequentially, the blades are notched or even ripped is effectively avoided, the plastic pulverizing quality is improved, and the service lives of the pulverizing blades can also be prolonged.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a plastic particle pulverizer with an adjustable blade angle. Background technique [0002] Plastics are polymer compounds that are polymerized from monomers through addition polymerization or polycondensation reactions. Plastics can be divided into soft plastics and hard plastics in terms of physical properties. In actual production, plastic particle crusher blades The angle of the knife barrel is inseparable from the softness and hardness of the plastic. When crushing soft plastics such as PVC, POE, and EVA, the angle of the plastic blade should be smaller. When crushing hard plastics such as ABS, PVC, and PC, the plastic blade should be smaller. The angle of the edge of the blade should be a bit larger. [0003] However, due to the imperfect technology of the existing plastic particle pulverizers, the blade angles of the blades are fixed and do not have the functio...

Problems solved by technology

[0003] And existing plastic granule pulverizer is because the technology is not perfect, and the blade angle of its blade is all fixed, does not have the function of angle adjustment, can't when pulverizing soft plastic, the blade angle of blade is turned down, so that can not be Soft plastics are more broken, and it is not possible to increase the angle of the blade when crushing hard plastics, so that the angle of the blade is too sharp and the blade is notched or even torn, which not only damages the crushing blade, but also affects the plastic. crushing quality
