Abstract

The invention provides a kraft paper gluing machine which sequentially comprises an unwinding mechanism, a front gluing mechanism, a short hot air circulating oven, a rear gluing mechanism, a long hotair circulating oven and a winding mechanism which are arranged on a frame according to a molding sequence. The front gluing mechanism comprises a front gluing roller, a front gluing adjusting rollerand a front gluing groove; and the rear gluing mechanism comprises a rear gluing roller, a rear gluing adjusting roller and a rear gluing groove. The front side and the rear side of kraft paper are glued through the front gluing mechanism and the rear gluing mechanism, meanwhile, the glued sides are heated and subjected to drying molding by using the short hot air circulating oven and the long hot air circulating oven, so that the front side and the rear side of release paper are glued with a water-soluble adhesive, the gluing efficiency and the gluing quality of the release paper are remarkably improved, the waterproof effect and the repeated use of the finished product release paper are effectively ensured, and the paper sources are greatly saved.

Description

technical field

[0001] The invention belongs to the field of release paper production equipment, in particular to a kraft paper gluing machine. Background technique

[0002] Release paper has moisture-proof, oil-proof and other isolation functions, and is widely used in food packaging, electronics, automotive foam, printing, adhesive tape, self-adhesive products and other industries. At present, the release paper is generally produced by coating both sides of kraft paper with waterproof glue and silicone oil. Most of the waterproof glue is coated with hot-melt adhesive film. The biggest disadvantage of this method is that the hot-melt adhesive film is not easy to penetrate into the kraft paper. In fact, the adhesive film is easy to be damaged, especially in the production of self-adhesive transfer, the release paper produced by this method can only be used twice at most, resulting in a great waste of paper.

[0003] Therefore, it is a difficult problem urgently needed by th...
