Description

Technical Field

[0001] The utility model relates to the technical field of modified plastics, in particular to a modified plastic particle vibrating screen. Background Art

[0002] Modified plastics refer to plastic products that are processed and modified by filling, blending, reinforcing, etc. on the basis of general-purpose plastics and engineering plastics to improve their flame retardancy, strength, impact resistance, toughness and other properties;

[0003] A Chinese patent with publication number CN209476670U was searched and disclosed a modified plastic particle anti-adhesion vibrating screen.

[0004] The above technical solution includes a base and a vibration screen box, wherein a vibration screen box is fixedly installed on the top of the base, a box cover is hingedly installed on the top of the vibration screen box, a feed funnel is fixedly installed on the top of the box cover, and a vibration motor is fixedly installed on one end of the vibration screen box. The utility model is convenient for users to fix the screen by fixing a fixed frame at the output end of the vibration motor to avoid unstable falling apart during vibration. After the high-temperature modified plastic enters, it passes through layers of screens and disperses into particles of different sizes. The cooling device reduces the temperature of the vibration screen box, and cold air enters the screen, so that the modified plastic enters from the feed funnel and is quickly cooled during the vibration grading process to prevent the plastic particles from sticking together due to high temperature. The purpose is to reduce the defective rate and improve the production quality of plastic particles. The device structure is simple and practical.

[0005] However, in the above scheme, after the technology screens the plastic particles, it cannot classify and collect the material heads, and the screened defective products will remain in the screen box. As the total screening amount increases, the defective products will be blocked in the screen box. This technology directly puts the raw materials into screening, but there are some defective products with extra-large diameters in the raw materials. Defective products of this diameter will quickly block the screen after entering the screen box, affecting the screening efficiency.

[0006] For this purpose, we propose a modified plastic particle vibrating screen. Utility Model Content
