Description

Technical Field

[0001] This application relates to the field of colored lightbox stickers, and in particular to an adhesive applicator for processing colored lightbox stickers. Background Technology

[0002] Colored lightbox stickers are a special material used for making lightbox advertisements and decorations. They are made of transparent polyester fiber fabric with high strength and weather resistance. During processing, adhesive is applied to the surface of the sticker using an adhesive applicator. After the adhesive is applied, a layer of PVC film is attached to the sticker to increase its peelability.

[0003] In the related technology, Chinese patent application number 202321797224.0 proposes to ensure that the adhesive does not solidify by stirring; however, it does not use an adhesive roller to apply the adhesive, resulting in uneven application.

[0004] While existing adhesive coating equipment includes double-roller, triple-roller, and quadruple-roller adhesive coating machines, the thickness of the lightbox sticker varies for different products. The existing adhesive coating rollers do not adjust the spacing between them, resulting in some products not being effectively coated with adhesive. Utility Model Content

[0013] By adopting the above technical solution, when it is necessary to adjust the distance between the first and second glue-applying rollers, the first cylinder is driven, and the first cylinder drives the second glue-applying roller to move along the first guide groove. Under the action of the transmission chain and auxiliary wheel, it is ensured that the second glue-applying roller will not experience transmission breakage during displacement, thus making it suitable for different thicknesses and sizes of light box stickers.

The squeezing roller is located above the second coating roller, and the axis of the squeezing roller is parallel to the axis of the second coating roller.

[0027] In one possible implementation, guide blocks are symmetrically arranged on the frame, and the second connecting rod is provided with guide grooves that cooperate with the guide blocks.

[0028] In one possible implementation, a scraper is provided on the frame, and a scraper blade is provided at one end of the scraper. The scraper blade is located on one end of the first coating roller, and there is a gap between the scraper blade and the first coating roller.

[0029] In one possible implementation, an adhesive collection trough is inclinedly provided on the frame, with one end of the trough extending through the frame. The trough is located at the lower end of the scraper plate, and a guide trough is inclinedly provided on the scraper plate.

[0030] In one possible implementation, a filter plate is provided on the glue collection tank.
