Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a UV glue coating mechanism. Background Art

[0002] UV glue is photosensitive glue. Its characteristic is that it is an adhesive that solidifies under ultraviolet light. In the process of processing membrane materials, it is often necessary to use a coating mechanism to coat the UV glue on the surface of the membrane material to ensure that the UV glue coating on the surface of the membrane material is uniform.

The patent adopts a frame, a conveying device, an adjusting device and a leveling device, and the conveying device, the adjusting device and the leveling device are all located on the frame. The setting of the adjusting device enables workers to flexibly adjust the spacing between the coating roller and the conveyor belt, so that the UV glue coating mechanism can apply UV glue to films of different thickness specifications, thereby improving the universality of the equipment; the setting of the leveling device enables the surface of the film material to be subjected to a force when the film material is transferred from the previous station to the UV glue coating mechanism, so that the surface of the film material between the coating roller and the leveling rod will be stressed and tightened, thereby ensuring that the film material is in a flat state during coating, preventing the film material from wrinkling or deforming during the coating process, etc., so as to solve the problem that the processing specifications of the existing coating equipment are mostly fixed, and due to the different thicknesses of the processed film materials, it is difficult to process films of different specifications when the equipment is processed.

[0004] The inventors have discovered in their daily work that in the process of using a coating mechanism to process film materials, there are existing coating mechanisms such as the above-mentioned ones that are only provided with a constraint component at the feed end. When the equipment is processing, due to the long distance between the discharge end of the equipment and the next processing equipment, when the coated film material is sent out from the discharge end, due to the long distance between the equipment and the lack of a guiding structure, the two ends of the film are prone to lateral displacement when being transported, which increases the lateral stress on the film, thereby causing the film to be prone to lateral cracking.
