Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic shielding film production technology, and in particular relates to a coating device for electromagnetic shielding film production. Background Technology

[0002] Electromagnetic shielding film is a material used to prevent electromagnetic interference and is widely used in electronic and communication equipment. In the production process, the coating unit is one of the key pieces of equipment, responsible for uniformly coating the electromagnetic shielding material onto the substrate.

[0003] Most existing coating machines are roller coating machines, and roller coating machines also vary greatly depending on the number of rollers. Ordinary two-roller coating machines only have a feed roller and a paint roller, and the gap between the feed roller and the paint roller is usually fixed, which cannot handle electromagnetic shielding films of different thicknesses, resulting in uneven coating and reduced coating quality. To address this, we have proposed a coating device for electromagnetic shielding film production, which uses three rollers to greatly improve the uniformity and quality of coating. Utility Model Content

[0004] The purpose of this invention is to provide a coating device for producing electromagnetic shielding films. Specifically, by setting up a coating assembly, the electromagnetic shielding film coating is pumped into a coating tank. The take-up roller and the transfer roller rotate in opposite directions, as do the back roller. The take-up roller picks up the electromagnetic shielding film coating from the coating tank and transfers the picked-up coating to the transfer roller. The prepared electromagnetic shielding film is placed between the transfer roller and the back roller. Pressure is used to squeeze the coated electromagnetic shielding film to the right side of the transfer roller and the back roller. The coated electromagnetic shielding film has a more uniform coating and can better achieve coatings with different thickness requirements. This invention solves the problem that most existing coating machines are roller coating machines, which vary greatly depending on the number of rollers. Ordinary two-roller coating machines only have a take-up roller and a coating roller, and the gap between the take-up roller and the coating roller is usually fixed, making it impossible to handle electromagnetic shielding films of different thicknesses, resulting in uneven coating and reduced coating quality.
