Abstract

Provided is a two-channel and three-layer co-composite compound machine. The two-channel and three-layer co-composite compound machine comprises a first coating unit, a second coating unit, a first compound unit, a second compound unit and an inter-machine guide roller mechanism; the first coating unit is provided with a first coating mechanism, a first unwinding mechanism and a first coating medium supply mechanism; the second coating unit is provided with a second coating mechanism, a second unwinding mechanism and a second coating medium supply mechanism; the first compound unit is provided with a first compound mechanism, a third unwinding mechanism and a first winding mechanism; the second compound unit is provided with a second compound mechanism, a fourth unwinding mechanism and a second winding mechanism; the inter-machine guide roller mechanism comprises a first guide roller set, a second guide roller set and a third guide roller set. The invention further discloses a use method of the two-channel and three-layer co-composite compound machine, two-layer composite and three-layer co-composite can be selected according to needs, and the advantages of being wide in adaptability, high in production efficiency and excellent in product quality control are achieved.

Description

technical field [0001] The invention belongs to the technical field of packaging and printing equipment, and in particular relates to a double-channel belt three-layer co-compositing compound machine and a use method thereof. Background technique [0002] At present, most of the solvent-free laminating machines used at home and abroad are two-layer laminating, single-station rewinding and unwinding structure. Its main components are: first unwinding unit, coating unit, second unwinding unit, composite unit, and winding unit. For example, the Chinese patent whose publication number is CN 101259772 discloses a solvent-free composite machine, which consists of a frame, a coating mechanism, a composite mechanism, a winding mechanism, a first unwinding mechanism, a second unwinding mechanism, a power mechanism, a wall Board, machine top, exhaust gas recovery part, cooling roller, transition roller group, swing tension roller group, and control box. There is a dust cover on the t...

Problems solved by technology

[0003] Although the solvent-free lamination machine can meet the requirements of use to a certain extent, it can only meet the requirements of two-layer lamination. With the continuous development of the packaging and printing market, the demand for two-layer and more than two-layer lamination Rapidly increasing, and the existing solvent-free lamination machine needs to use multiple laminations to meet the lamination of more than two layers, resulting in reduced production efficiency and increased difficulty in product quality control
