In the current society, it is machinery and equipment that can solve the production problems of enterprises. In the hot melt adhesive coating machine industry, as long as it can save labor costs, it is good equipment to make good products. Humanized processing equipment refers to: reducing manual operations and realizing greater corporate benefits. Hot melt adhesive coating machines are currently hot in the domestic market. This equipment is also imported from abroad. The research and development of this equipment has been successfully developed in the waterproof building materials industry. The big support has since solved the cost problem of our country in the waterproof building materials industry. The equipment price is high, but the production efficiency is very high.
At present, the industrial coating systems suitable for medical hot melt adhesives include roll coating system, pattern roll coating system, spray coating system, slit coating system, extrusion coating system and screen coating system. The roller coating system is often used for the coating of medical hot melt adhesives with high viscosity. After being melted in the melt system, it is transported to the glue reservoir of the glue system. The glue reservoir is equipped with a liquid level sensor and the signal generated by the sensor Feedback to the glue delivery system is used to control the size of the pump glue. The glue in the glue storage is sent between the operating roller and the coating roller. The pressure between the two rollers that rotate in the opposite direction will cause the glue to emerge from the gap between the two rollers.
Extrusion in sheet form and coating on the substrate by the operating roller. Adjusting the distance between the coating roller and the operating roller can adjust the thickness of the glue coating. Roll coating can be used for single-sided coating or double-sided coating. .
