Description

Technical Field

[0001] The invention relates to the technical field of UV light-curing film processing, in particular to a UV light-curing film multi-point glue injection coating processing device. Background Art

[0002] UV light-curing film generally includes a base film and a UV adhesive layer. The base film is commonly a PET film, and the UV adhesive layer is a light-curing layer. During the film coating process, it is usually necessary to invert the UV glue into the ink tank in advance. The ink tank is usually designed to be open. During the film coating, the mesh roller is dipped into the ink tank to dye the ink, and then the UV glue is stored on the concave and convex surface of the mesh roller; the PET film is printed and coated by the mesh roller storing the UV glue, and then the PET film is coated with UV glue. The UV glue is cured after being processed by the photosensitive device to finally form a UV adhesive layer. The PET film and the UV adhesive layer together form a UV light-curing film.

[0003] The processing device in the prior art has a complex structure, and does not solve the problem of dust entering the gluing process during use, which makes it easy to affect the gluing roller during glue injection. Secondly, the glue injection amount cannot be guaranteed to be in an average state during use, which easily leads to excessive glue injection and excess glue waste. Summary of the invention

[0009] Furthermore, a pair of limiting rollers are integrally installed in the protection block through a connecting plate, and the pair of glue coating rollers are located between the pair of limiting rollers.

[0010] The beneficial effect of adopting the above further technical solution is that the setting of the limiting roller facilitates the tensioning and limiting of the PET film.

[0011] Furthermore, a glue box is provided on the top of the protection block; the glue dispensing mechanism includes: a glue injection needle, a glue injection tube and a driving mechanism, the glue injection needle is connected to the glue box through the glue injection tube, and the glue injection needle is slidably installed in the protection block through the driving mechanism.
