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;
