Abstract
Description
Technical Field

[0002] Plastics are materials made of high molecular polymers, characterized by their lightweight, durability, and high plasticity. They are widely used in daily life and industrial fields. Modified engineering plastics are ordinary plastics modified through physical or chemical methods to significantly improve their properties. Common modification methods include reinforcement modification, filler modification, blending modification, and chemical modification. During the production of modified engineering plastics, they need to be screened to remove unqualified particles, dust, and other impurities. Therefore, a screening machine for the production of modified engineering plastics is required.
[0003] Existing screening machines for modified engineering plastics production have certain drawbacks. In use, these machines typically employ screening boxes to screen modified engineering plastic particles. These screening boxes usually use vibration screening, but to improve screening efficiency, the vibration amplitude of the screening box is usually large, resulting in significant noise that affects the working environment. Conversely, using a smaller vibration amplitude reduces the screening efficiency and fails to meet user needs. Utility Model Content
