Dry-type compound machine

Abstract

The invention discloses a dry-type compound machine. The dry-type compound machine comprises a drying tunnel, a coating device, a compound device, a first unreeling mechanism corresponding to the coating device, and a second unreeling mechanism and a reeling device both corresponding to the compound device, wherein the coating device and the compound device are arranged under the two ends of the drying tunnel, respectively; the coating device is a five-roller coating device which comprises roller frames located on the two sides, and a five-roller coating mechanism, a guide roller I for guiding a first base material unreeled by the first unreeling mechanism to the five-roller coating mechanism and a guide roller II for guiding the first base material coated with glue by use of the five-roller coating mechanism to the drying tunnel are arranged between the two roller frames. The coating glue of the five-roller coating device can be high-concentration glue, and therefore, the problem of environmental pollution caused by glue leakage due to excessive diluent can be avoided; in addition, the coating amount of the coating glue on the first base material can be adjusted conveniently by adjusting the rotating speed of the five-roller coating mechanism, and the adjustment of the coating amount is simpler and more accurate.

Description

technical field [0001] The invention belongs to the technical field of packaging and printing equipment, in particular to a dry composite machine. Background technique [0002] The dry lamination machine is a machine that sticks different plastic films together to form a composite film through a dry lamination process. The dry compounding process is to fully dry the solvent in the glue solution by heating and exhausting after the glue is applied, and then compound in a "dry" state. In view of the fact that the dry laminating machine can laminate different plastic films, aluminum foil and even paper, the requirements for the dry laminating machine are relatively high. [0003] The dry compound machine generally consists of an anilox roller coating mechanism, a first unwinding mechanism, a drying tunnel, a second unwinding mechanism, a composite mechanism and a winding mechanism. Rolling and other process steps complete the compounding of the substrate. For example, the Chi...

Problems solved by technology

[0005] 1. Since the existing dry laminating machine still uses the anilox roller coating mechanism to apply glue to the first substrate, a large amount of glue-coating solvent is required, and a large proportion of diluent is required in the ratio of glue-coating solvent , resulting in an increase in cost and easy to pollute the environment;

[0006] 2. The amount of coating is not easy to control. When the existing dry compound machine needs to change the coating amount, it is necessary to replace the anilox roller, which is not only troublesome to operate, but also needs to prepare various types of screens for different coating amount requirements Textured roller, increased equipment investment
