Heat treatment equipment for membrane material

Abstract

The invention discloses heat treatment equipment for a membrane material. The heat treatment equipment comprises a feed roller, a plurality of guide rollers, a wrap angle roller, a heating roller, a constant-temperature roller, a precooling roller, a cooling roller and a winding roller, wherein the membrane material is guided through the plurality of guide rollers and sequentially passes through the feed roller, the wrap angle roller, the heating roller, the constant-temperature roller, the precooling roller, the cooling roller and the winding roller for heat treatment. The heat treatment equipment is characterized by further comprising a wrap angle roller moving mechanism enabling the wrap angle roller to move to adjust the wrap angle of the membrane material on the heating roller. With the adoption of the heat treatment equipment for the membrane material, according to the material characteristic of the membrane material, the best adhesive strength of the membrane material can be obtained through controlling of contact area and contact time of the membrane material and the heating roller and matching with temperature adjustment of the heating roller.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a membrane material heat treatment equipment. Background technique [0002] With the rapid development of various polymer functional membrane materials in the market in recent years, the industry has more and more requirements for membrane materials, especially the rapid development of the photovoltaic industry in recent years, the backplane made of membrane materials With the characteristics of lightness and high performance, it has completely replaced tempered glass as the back protection layer of the battery module. Based on the current market standard that requires the service life of the module to be more than 25 years, in the actual production process of the solar battery module, it is required that the film The bonding strength of the material and the component is at least 40N / cm after being laminated with EVA, which requires the surface bonding performance o...

AI Technical Summary

Problems solved by technology

In the existing technology, the device of wrapping angle roller is not added, and the contact time is adjusted simply by adjusting the speed, but the contact area cannot be adjusted, so that it is impossible to select the corresponding treatment plan according to different films and fail to achieve the corresponding required treatment effect.
