Solvent-free printing compound machine and solvent-free printing compound process

Abstract

The invention discloses a solvent-free printing compound machine and a solvent-free printing compound process using the same. The solvent-free printing compound machine comprises a paper unwinding device, a multi-color printing unit, a film unwinding device, a coating compound unit and a paper winding device. The solvent-free printing compound process comprises the following process steps that S1, a base material A is input through the paper unwinding device; S2, a plurality of sets of printing units are used for sequentially conducting solvent-free intaglio printing on the base material A for a plurality of times; S3, a base material B is input by using the film unwinding device, and the base material B is compunded onto the base material A by using the coating compound unit to form a composite material, so as to obtain a finished product; and S4, the finished product is wound by using the paper winding device. The procedures in the step S2 and the step S3 are continuous and uninterrupted. The method has the advantages of few process steps, continuous working, high working speed and reduced manpower. The solvent-free printing compound machine and the solvent-free printing compound process are suitable for solvent-free printing compounding.

Description

【Technical field】 [0001] The invention relates to the technical field of solventless printing, in particular to a solventless printing composite machine and a solventless printing composite process using the printing composite machine. 【Background technique】 [0002] Solvent-free composite refers to a composite technology that does not contain organic solvents. It does not need to add any organic solvents during use, has no volatility, and has no emission of organic volatiles. Compared with solvent-based and water-based dry lamination, solvent-free lamination has obvious advantages in terms of glue application cost, energy saving, and emission reduction. [0003] Solvent-free printing means that the ink does not contain organic solvents, no need to add any organic solvents during use, no volatility, no emission of organic volatiles. [0004] In the existing process, compounding and printing are separated, and after compounding and winding, they are manually transported to t...

Problems solved by technology

[0004] In the existing process, compounding and printing are separated, and after compounding and winding, they are manually transported to the printing unit for printing. This method has the following disadvantages: 1. The work is not continuous, and it takes a while to print after compounding. The speed is slow; 2. It requires a lot of manpower, and it takes a waste of manpower to transfer the laminated coil and transport it to the printing unit. Before printing, it needs to be installed and adjusted slowly, which wastes manpower and time; 3. There are too many between lamination and printing. The two steps of winding and unwinding make the quality of the finished product unstable; 4. The equipment is independent and requires a lot of equipment
