Problems solved by technology

[0006] However, there are still some deficiencies in the existing production equipment of the Freon-resistant composite enameled wire wrapped with glass filaments. During processing, the enameled wire cannot be dipped in a rapid cycle, which reduces the production of the enameled wire by the device. At the same time, it is impossible to perform integrated treatment of dipping, solid-state and winding on the enameled wire, which reduces the production efficiency of the enameled wire. Therefore, a production device for Freon-resistant composite enameled wire wrapped with glass filaments is needed to solve the above-mentioned problems.

Description

technical field [0001] The invention relates to the technical field of composite enameled wire production, in particular to a production process and equipment for Freon-resistant composite enameled wire wrapped with glass filaments. Background technique [0002] Composite coated enameled wire is derived from ordinary single-coated enameled wire. Its paint layer is composed of primer inner paint layer and surface outer paint layer. Therefore, its type mainly refers to the variety and combination of inner and outer paint layers. Generally speaking, for the primer layer, in principle, any variety of the existing single coating is used, mainly concentrated in polyaminophenol, polyphenol and polyphenolimide, etc., and the outer layer is selected according to performance requirements and service conditions. There are mainly polyvinyl butyral, epoxy, polyamide and polyphthalimide and their modified resins. [0003] According to Chinese Patent No. CN201610541685.X, the embodiment o...
