Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic material production, in particular to a screening machine for rubber and plastic material production. Background Art

[0002] In the manufacturing process of resin-type rubber and plastic fibers, some waste materials (waste paper, waste cotton, waste hemp, etc.) are needed. At present, before the recycled waste paper is used, there will be more or less gravel inside the waste paper, so the waste paper needs to be preliminarily screened before use.

[0003] The Chinese patent document with the publication number CN211865757U discloses waste screening equipment for the production of resin-type rubber and plastic fibers, which solves the problem of manual separation of waste paper and gravel, which is labor-intensive and has low screening efficiency. It includes a support seat, and support legs are arranged at the four corners of the bottom end of the support seat. The upper end of the support seat is open, and the bottom end of the support is opened. A screening box is arranged inside the support seat, and the four corners of the outer end of the screening box are fixed to the four corners of the inner side of the support seat by springs, and vibration motors are installed on the outer walls of both sides of the screening box. In view of the above technical scheme, there are the following defects in use: in the process of screening stones in waste paper in the prior art, waste paper is easy to block the sieve hole, which will affect the screening effect of the sieve hole. In addition, small stones are easy to block the sieve hole, which requires manual cleaning, and the operation is time-consuming and labor-intensive. Utility Model Content
