Premixing-free solvent-free compound machine and grouping pre-coating solvent-free compound method

Abstract

The invention firstly discloses a premixing-free solvent-free compound machine. The premixing-free solvent-free compound machine comprises a first coating device, a second coating device and a compound device. A first coating mechanism and a first unwinding mechanism are arranged on the first coating device. A second coating mechanism and a second unwinding mechanism are arranged on the second coating device. A compound mechanism and a winding mechanism are arranged on the compound device. A first guide roller set used for guiding a first base material to the compound mechanism is arranged between the first coating mechanism and the compound mechanism. A second guide roller set used for guiding a second base material to the compound mechanism is arranged between the second coating mechanism and the compound mechanism. The invention further discloses a grouping pre-coating solvent-free compound method. According to the premixing-free solvent-free compound machine and the grouping pre-coating solvent-free compound method, the technical problems, caused by the fact that coating is carried out after a first coating medium and a second coating medium are premixed, of an existing solvent-free compound machine can be directly solved, and the beneficial effects that the mixing ratio of the first medium and the second medium is controlled precisely, and the coating quantity is more precise are achieved.

Description

technical field [0001] The invention belongs to the technical field of packaging and printing equipment, and in particular relates to a premix-free and solvent-free lamination machine and a group pre-coating and solvent-free lamination method. Background technique [0002] Solvent-free lamination machine is a method of laminating two or more substrates together with a solvent-free adhesive, also known as reactive lamination. Existing solvent-free composite machines generally include a coating device and a composite device, the coating device is provided with a first unwinding mechanism and a coating mechanism, and the composite device is provided with a second unwinding mechanism, a composite mechanism and a winding mechanism. Mechanism, the first base material on the first unwinding mechanism is coated by the coating mechanism and then compounded with the second base material of the second unwinding mechanism on the composite mechanism. For example, the Chinese patent with...
