Description

Teflon film adhesive tape coating curing device Technical Field The utility model relates to the technical field of film adhesive tape processing, in particular to a curing device for a coating of a Teflon film adhesive tape. Background In the production process of the Teflon film adhesive tape, the curing of the coating is a crucial link, and the curing effect directly influences the quality and performance of the Teflon film adhesive tape. At present, the existing curing device for the Teflon film adhesive tape coating has a plurality of defects in practical application. On the one hand, many conventional curing devices employ a single stage curing process, i.e., curing the film tape at the same temperature. The method cannot fully consider the different requirements of the Teflon film adhesive tape on temperature at different stages, and the film is easy to generate larger stress due to abrupt temperature change, so that the physical performance and appearance quality of the film are affected. Meanwhile, a single-temperature curing mode is difficult to realize an efficient curing process, the curing time is long, the production efficiency is low, and the ever-increasing production requirements cannot be met. On the other hand, in terms of the heating mode, some conventional devices rely only on conventional heating modes such as an electric heating rod. The electric heating rod mainly transmits heat through a conduction mode, and the heating mode is not uniform enough for the film adhesive tape coating, so that the temperature difference between the surface and the inside of the coating is easily caused.
