AI Technical Summary

Technical Problem

Existing plastic production screening devices have limited opportunities for material to contact the screen during vibrating screening, resulting in low screening speed and easy clogging. In particular, when a large amount of material is fed in, the upper layer of material is blocked by the lower layer, affecting the screening effect.

Method used

The screening method employs bidirectional motion. The electric motor drives the rotating column and pulley to move the screening cylinder and the hollow rotating rod tipping plate to turn the material. Combined with high-pressure gas cleaning of the screen holes, it ensures uniform material distribution and thorough cleaning, preventing blockage.

Benefits of technology

It achieves full dispersion and uniform distribution of materials, improves screening rate, reduces screen clogging, and ensures thorough and efficient screening effect.

Abstract

This utility model belongs to the field of modified material screening technology, specifically a screening device for plastic production. It includes an outer cylinder, inside which a screening cylinder is rotatably installed. Both ends of the screening cylinder are fitted with toothed rings. Two fixed frames are fixedly connected to the top of the circumferential surface of the outer cylinder. A rotating column is rotatably installed on the two fixed frames. Gears are fitted at both ends of the rotating column, and the gears are housed within the fixed frames, meshing with the toothed rings. A motor is installed on one side wall of one of the fixed frames, and the output end of the motor is connected to one end of the rotating column. During screening, this utility model can fully disperse the material, evenly distributing it within the screening cylinder. This effectively prevents localized accumulation of material within the screening cylinder, reduces sieve hole blockage, and allows small particles to pass through the sieve holes more easily, while larger particles remain inside the screening cylinder, thus achieving a more thorough screening effect and greatly improving the screening rate.
