Description

Technical Field

[0001] This utility model relates to the field of foam production technology, specifically to a quantitative feeding device for raw materials used in foam production. Background Technology

[0002] In the foam production process, it is often necessary to mix various raw materials with different properties in precise proportions. The quantitative feeding of raw materials is the core of the entire production process. Its precision and stability directly determine the key properties of foam products such as density and strength, and are the key to ensuring that the product quality meets the standards and is stable.

[0003] Currently, commonly used foam production raw material quantitative feeding devices suffer from several drawbacks in the foam raw material conveying process. Some raw materials are hygroscopic or sticky, making them prone to accumulating at the bottom of storage silos, at the discharge port, and within the conveying pipes. Especially when raw materials are stored for extended periods, localized pressure can cause clumping. These accumulations and clumps gradually block the feeding channels, leading to interruptions in raw material delivery and requiring machine shutdowns for cleaning, severely impacting production continuity. Furthermore, troubleshooting relies heavily on manual operation, requiring operators to frequently check storage silo levels, manually adjust the feeding valve opening, and manually disassemble and clean pipes. This increases labor costs and reduces overall production efficiency, failing to meet current demands. Utility Model Content
