Medical adhesive plaster coating device and medical adhesive plaster coating method

Abstract

The invention provides a medical adhesive plaster coating device and a medical adhesive plaster coating method. The device is characterized by comprising an unwinding roller, a guide roller, a coating roller, a cooling roller, a mould pressing roller, a winding roller, a coating device body and base cloth. The base cloth is fixed to the unwinding roller, the end of the base cloth sequentially penetrates through the guide roller, the coating roller, the cooling roller and the mould pressing roller to be arranged on the guide roller, the coating roller, the cooling roller and the mould pressing roller in a tightened mode, the end of the base cloth is fixed to the winding roller, the coating device body is arranged on the outer side face of the coating roller, the guide roller, the mould pressing roller and the winding roller are located below the unwinding roller, the coating roller and the cooling roller, the unwinding roller, the coating roller and the cooling roller are located in the same horizontal position, the guide roller is provided with two direction-changing guide roller bodies and two pressing guide roller bodies, and the two pressing guide roller bodies are located between the direction-changing guide roller bodies. The device and the method solve the problems that a traditional medical adhesive plaster is high in technological risk and energy consumption and low in efficiency, and eliminate environmental pollution, a drying tunnel does not need to be used, coating speed can reach 60m / min, and production efficiency is improved by three times.

Description

technical field [0001] The invention belongs to the technical field of preparation technology of medical adhesive plaster, in particular to a medical adhesive plaster coating device and a medical adhesive plaster coating method. Background technique [0002] Medical adhesive plaster has been used in medical clinics for many years. The production process of medical adhesive plaster uses rubber as the adhesive, high-grade gasoline as the solvent, and medicinal zinc oxide as the filler. The production process generally includes gluing, stirring, scraping, and drying. , Rewinding and other processes. [0003] The traditional process of producing medical adhesive plaster mainly has the following defects: (1) there are relatively large safety hazards, and high-grade gasoline is used as a solvent, which is prone to explosion accidents during the production process; (2) gasoline is a volatile liquid, Gasoline volatilizes into the air during the process, causing pollution to the env...
