Description

Technical Field

[0001] The utility model relates to the field of polyimide film production, in particular to an anti-adhesion device used in the production of polyimide films. Background Art

[0002] Polyimide film is a high-temperature resistant motor and electrical insulation material with outstanding high-temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation properties. Polyimide film can be used for motor slot insulation and cable wrapping materials and is a very common material.

[0003] After searching, the applicant found that a Chinese patent disclosed "a production device for polyimide film", and its publication (announcement) number is "CN216506298U". This patent mainly sets a stirring device so that the material is first stirred by the stirring device before entering the casting device, which can ensure the uniformity and accuracy of feeding, and at the same time prevent blockage or discontinuous and unsmooth feeding. By setting a vibration stress relief device, compared with removing stress by thermal aging method, not only the internal stress is eliminated faster, but also the damage to the film caused by multiple heating can be avoided while being environmentally friendly. By setting a blower, dust and other debris adhering to the top of the film can be blown off. , plays a role in dust removal to prevent it from affecting the quality of the final product. By setting a tension adjustment device, the tension of the film can be adjusted to prevent the film from wrinkling due to excessive relaxation, which affects the quality of the finished product. However, the traditional equipment for producing polyimide film does not have an anti-adhesion device, which causes the polyimide film to easily stick to the equipment when the equipment is producing the polyimide film. The residual polyimide film on the equipment will also affect the next use of the equipment, reducing the efficiency of the equipment, and will also affect the quality of the polyimide film produced next time, greatly reducing the use effect of the equipment. At this time, an anti-adhesion device for the production of polyimide film is needed to solve the above problems. Utility Model Content
