Description

Technical Field

[0001] The utility model relates to the technical field of self - adhesive PE films, in particular to a device for preparing self - adhesive PE films. Background Technique

[0002] The self - adhesive PE film is a polyethylene film with self - adhesiveness, mainly used for the protection of product surfaces to prevent contamination, scratching or other damages during production, transportation and storage. The self - adhesive PE film uses polyethylene (PE) as the base material and has self - adhesive properties by coating a layer of pressure - sensitive adhesive on its surface. This film can effectively prevent products from being contaminated or scratched during production, processing, transportation, storage and use, thereby protecting the original smooth and shiny surface of the products and improving the quality and market competitiveness of the products. The main material of the self - adhesive PE film is usually LDPE (low - density polyethylene), which has the advantages of being soft and easy to stick, no residual glue after peeling and excellent air - exhaust performance. Its structure mainly consists of three parts: the release layer (PE series), the support layer (PE series) and the adhesive layer. These characteristics enable the self - adhesive PE film to meet the surface protection requirements of various products.

[0003] Common self - adhesive PE film preparation devices include a feeding system, a surface treatment unit, a coating system, a drying system, a cooling system and a winding system. The feeding system unfolds the original PE film material from the reel, performs corona treatment to enhance the adhesion between the film and the pressure - sensitive adhesive, and then evenly coats the pressure - sensitive adhesive on the surface of the PE film. The coated PE film needs to pass through the drying system to remove the solvent and cure the pressure - sensitive adhesive. The dried PE film is wound up after cooling for easy storage and transportation.

[0004] For common self - adhesive PE film preparation devices, the original PE film material needs to be pulled out from the feeding system before production, passed through each production system, and finally reach the winding system. Due to the small space inside each system, a large amount of time is required for the initial installation of the original PE film, increasing the workload of the staff and reducing the production efficiency. In view of this, this application proposes a device for preparing self - adhesive PE films. Content of the Utility Model

[0013] Further, a drying assembly for drying the self-adhesive PE film and a cooling assembly for cooling the dried self-adhesive PE film are fixedly installed between the two support vertical plates.
