Description

Technical Field

[0001] The utility model relates to the technical field of shielding film production devices, in particular to a coating device for producing electromagnetic shielding films. Background Art

[0002] Electromagnetic shielding film is a film that uses the reflection and attenuation of the shielding body to prevent the electromagnetic energy flow generated by the electromagnetic radiation field source from entering the shielded area, thereby protecting the equipment from external electromagnetic radiation interference and ensuring the normal operation of the equipment. Coating is a method of coating a paste polymer, a molten polymer or a polymer melt on paper, cloth, or plastic film to obtain a film. In the production of electromagnetic shielding film, coating is also one of the indispensable processes.

[0003] Currently, there are many ways to coat electromagnetic shielding films, such as roller coating, air knife coating, doctor blade coating and spray coating. Spray coating utilizes a nozzle to coat the electromagnetic shielding film cloth, but the existing large-scale spray coating devices have a small number of nozzles and a limited spraying range. When targeting wider electromagnetic shielding film cloths, the electromagnetic shielding film cloths are easily not sprayed on both sides, resulting in uneven spraying, which affects the overall quality of the electromagnetic shielding film.
