Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic material screening technology, specifically a raw material screening device for paint and ink production. Background Technology
[0002] Vibrating screens are key devices for ensuring uniform particle size of raw materials and removing impurities. Their working principle is that the working part is fixed, and the material is screened by vibrating and sliding along the working surface.
[0003] Existing vibrating screening devices, which screen materials by pouring them onto the screen plate and then using vibrating components, cause the materials to accumulate on the screen surface, making it impossible for them to pass through the screen in a timely and even manner, thus reducing screening efficiency. Furthermore, the large amount of material accumulating on the screen plate can clog the holes in the screen plate, affecting the normal use of the device, and thus presenting limitations.
[0004] The reason for this problem is that the accumulation of material on the screen surface obstructs the screening process, causing fine particles that should pass through the screen holes to be trapped in the accumulated material and unable to be discharged in time. This not only reduces screening efficiency but also leads to inaccurate screening results. Due to factors such as static electricity, some tiny particles in the accumulated material can clog the screen holes, further reducing screening efficiency. Therefore, we propose a raw material screening device for paint and ink production to solve the above problems. Utility Model Content
