Abstract

The invention relates to the technical field of plastic processing, in particular to a corrugated pipe production raw material screening device. The screening box comprises a screening box. A screen net is arranged on the top of the screening box. A first partition board, a second partition board and a third partition board are sequentially arranged in the screening box. The first partition board,the second partition board and the third partition board divide the screening box into a first-stage storage cavity, a second-stage storage cavity, a third-stage storage cavity and a fourth-stage storage cavity. The screen net is arranged obliquely. Springs are connected between the screen net and the screening box. The screen net comprises a first-stage screening net, a second-stage screening net and a third-stage screening net which are arranged above the first-stage storage cavity, the second-stage storage cavity and the third-stage storage cavity correspondingly. The diameters of net holes of the first-stage storage cavity, the second-stage storage cavity and the third-stage storage cavity increase in sequence. A cam is arranged at the high end of the screen net. The cam can abut against the screen net. Through the corrugated pipe production raw material screening device, the problem that the size difference of each kind of plastic particles is large in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a screening device for corrugated pipe production raw materials. Background technique [0002] In the production process of the bellows, the plastic particles are first heated and melted, and then the melted plastic is used to shape the shape, and the final product is formed after cooling. However, the existing plastic particles may be uneven in size due to cutting errors or improper operation, and plastic particles of different sizes are prone to uneven heating when heated and melted, which will seriously affect the bellows later stage. processing and production. [0003] In order to solve the above problems, a granular plastic classifier with the publication number CN203955528U includes a main body, and is characterized in that: the main body is provided with a blanking cavity, a sieve plate and a vibrator, and the sieve plate will drop The material cavity is divid...
