Problems solved by technology

Obviously, this measure is a negative method. Although it can improve the quality of the product, it reduces the production speed of the product, reduces the output of the product, and greatly reduces the production efficiency. It can only be used as an expedient measure when there is no good method. Not a recommended and used method, it is very necessary to improve

Abstract

The invention relates to the field of package printing equipment and in particular relates to a solvent-free compounding machine. A compounding machine body is provided with an unwinding device and awinding device. The unwinding device is provided with a first unwinding unit, a first deviation correction unit and a coating unit; the winding device comprises a second unwinding unit, a second deviation correction unit, a compounding unit and a winding unit. A guide roller group for leading a first base material for coating a first coating medium of the coating unit to the compounding unit is arranged between the first unwinding unit and the compounding unit. According to the solvent-free compounding machine, the heat is uniformly reduced in a water cooling manner through a water cooling coating back-pressing steel roller; and the precision problem, caused by cold shrinkage and thermal expansion, on the coating back-pressing steel roller is reduced. A water cooling unit is arranged behind the compounding unit so that the cooling effect of a composite membrane is accelerated and the production efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the field of packaging and printing equipment, in particular to a solvent-free composite machine. 【Background technique】 [0002] At present, the development of the flexible packaging industry is very rapid, and solvent-free compounding has achieved rapid growth in the compound flexible packaging industry due to its advantages of high speed and environmental protection. However, due to the fast speed of solvent-free compounding, the unstable gap between the coating rollers leads to uneven glue application, and the unstable glue will affect the quality of the product, and the solvent-free composite aluminum foil film and PET aluminized film are also very unstable, resulting in The problem of laminating aluminum foil film and PET aluminized film cannot be effectively solved when using ordinary solvent-free laminating machine. The current measure to solve the instability of products after solvent-free compounding is to prolong ...
