Description

TECHNICAL FIELD

[0001] The utility model relates to polyurethane glue production technical field, specifically for high strength polyurethane glue production feeding device. BACKGROUND

[0002] As a kind of sealing material with polyurethane rubber and polyurethane prepolymer as main component, polyurethane sealant is widely used in many fields with its high tensile strength, excellent elasticity, outstanding wear resistance, oil resistance and cold resistance.

[0003] In the production process of polyurethane sealant, powder is an indispensable raw material. At present, the addition of powder generally relies on workers to transport powder into the production equipment through the filling port, and then the powder is scattered by the stirring rod inside the equipment for subsequent production use. However, the powder is prone to caking after long-term standing. This not only causes the caked powder to block the material port during transportation, seriously affecting the discharge speed and thus reducing the production efficiency, but also greatly reduces the quality of finished polyurethane sealant.

[0004] To solve this problem, the conventional method is to scatter the powder again during the feeding process to reduce the number of caked powder. However, due to the large difference in the size of the caked powder, a single scattering operation cannot completely restore the powder to its initial state without caking, and cannot fundamentally solve the series of production problems caused by powder caking. Therefore, it is urgent to develop a high-strength polyurethane glue production feeding device. UTILITY MODEL CONTENTS
