Description

Technical Field

[0001] This utility model relates to the field of unclogging filter mesh, specifically to a filter mesh unclogging component for an extruder. Background Technology

[0002] Extruder filters are a crucial component of extruders, primarily used to filter impurities in the melt to ensure the production of qualified products. Filters are typically woven from metal wire or high-temperature resistant materials, intercepting impurities in the melt and preventing them from entering the die, thus guaranteeing product quality. There are two main types of extruder filters: sheet type and belt type. The specifications of the filter are usually determined by its mesh count; a higher mesh count results in better filtration but also increases filtration resistance. Extruder filters are widely used in the production of various viscous materials and products, including plastics, synthetic fibers, rubber, hot melt adhesives, coatings, and mixtures. Through filtration, products meeting quality requirements can be produced, and they are widely used in packaging, construction, automotive, and electronics industries. A Chinese patent discloses a vulcanized capsule-type strip extruder head (authorization announcement number CN 215040116). This patented technology, by adding filter plates and screens, effectively prevents impurities from passing through the rubber compound. Secondly, the increased resistance to the rubber compound's movement due to the filter plates and screens improves its plasticization within the barrel. However, this design lacks a mesh unclogging component at the filter plates and screens, making it prone to accumulating dirt and debris, increasing the risk of clogging. Therefore, those skilled in the art have provided a mesh unclogging component for an extruder to address the problems mentioned in the background section. Utility Model Content
