Film laminating machine drying system and film laminating machine pasting system formed by film laminating machine drying system

Abstract

The invention discloses a film laminating machine drying system which comprises a drying cavity which is a closed space. A heating device and a moisture expelling device are arranged in the drying cavity, a blower device blows air heated by the heating device to an adhesive film, an air blowing face of the heating device is an arc-shaped face suitable for a roller face of the drying roller, one end of a moisture recovering pipe of the moisture expelling device is arranged in the drying cavity, the other end of the moisture recovering pipe is connected with a moisture pumping fan, and moisture in the drying cavity is pumped away from the drying cavity through the moisture pumping fan; a controller is connected with the heating device and the moisture expelling device, and the controller can at least achieve pressure balance in the drying cavity or adhesive film drying by controlling the rotating speed and the temperature of the drying roller and starting and stopping of the heating device and the moisture expelling device. The invention further discloses a film laminating machine pasting system with the above film laminating machine drying system. By means of the film laminating machine drying system and the film laminating machine pasting system, heat losses can be avoided, the adhesive film drying effect is improved, energy resources can be saved, the product quality is improved, defective printing products are avoided, production waste is avoided, and raw material waste is avoided.

Description

technical field [0001] The invention relates to a printing device, in particular to a drying system of a laminating machine in a post-press process. The present invention also relates to a laminating machine bonding system having the laminating machine drying system Background technique [0002] Laminating process (laminating), also known as "lamination", "mounting glue", "film sticking", etc., refers to the use of transparent film to apply heat and pressure to the surface of printed products to protect and increase gloss. The laminating machine is a special equipment for paper and film. It has a wide application range and stable and reliable processing performance. It is a laminating equipment widely used in China at present. [0003] Dry laminating machine, the film is coated with solvent-based glue first, and then bonded to the paper after drying. During the drying process, there are drying rollers and drying boxes, each of which has a heating device. The drying rollers ...

AI Technical Summary

Problems solved by technology

[0005] 1. Moisture will be generated when the glue is dried (the water in the glue evaporates). If it is dried in a completely open space, energy will be wasted. If it is dried in a completely closed space, the moisture will affect the drying effect

[0006] 2. In the prior art, the drying equipment runs immediately after starting up, and does not monitor the drying effect of the film. The drying system has a large heat loss and high power consumption of the equipment, which is not conducive to energy saving and environmental protection.

[0007] 3. In the prior art, the drying equipment runs immediately after starting up, and the subsequent lamination is carried out without checking the drying effect of the film. If the drying system fails, the moisture content of a certain batch of glue is high, etc., the film is not completely dry or does not reach the lamination If the standard is met, it will be bonded, which will affect the quality of the coated product

If the operator fails to find out that the film is not completely dry or does not meet the bonding standard, the product quality will be reduced, and even a large number of defective printed products will be produced, resulting in production waste
