Problems solved by technology

Traditional printing machines adopt the form of placing the printing machine and embossing machine horizontally. Due to the limitation of the volume of the embossing machine, this form cannot shorten the length of the film between the printing machine and the embossing machine, resulting in film deformation and inability to Problems aligning printed and embossed patterns
[0004] In the existing film embossing devices, a single motor is used to drive the embossing roller to rotate, and the rubber roller is passively operated to realize the embossing of the film. The biggest disadvantage of this design is that if the printing pattern and the embossing roller If the lines do not match, when it needs to be adjusted, it is necessary to speed up or slow down the printing speed of the printing roller, and there is a long distance between the printing roller and the embossing roller. To make the speeds of the two consistent, adjust During the period, a very long amount of material needs to be wasted, and it needs to be adjusted to be completely consistent, requiring multiple trials to meet the requirements
In addition, since this design adjusts the printing speed according to the embossing speed, the film basically pulls the film forward through the rotation of the embossing roller, and the length of the film between the embossing roller and the printing roller is longer, and the film The tensile force is relatively large, and the film will be deformed by the tension during this process, making it more difficult to achieve the correspondence between the printed pattern and the embossed pattern

Abstract

The invention relates to a printing machine. The printing machine comprises a printing assembly and an embossing assembly. The printing assembly comprises a plurality of printing rollers, and a film enters the embossing assembly after being printed by the printing rollers. The embossing assembly is arranged above the printing assembly. According to the printing machine, the embossing assembly is arranged over the printing rollers or above the printing rollers, so that the traditional mode of placing the embossing assembly and the printing rollers in parallel is changed, he length of the portion, between the embossing assembly and the printing rollers, of the film is shortened, the influence that the film is deformed due to tension action is reduced, a printing pattern can be accurately aligned to an embossing pattern, and the product quality is improved.

Description

【Technical field】 [0001] This invention relates to printing machines. 【Background technique】 [0002] Composite film is a polymer material composed of two or more layers of films of different materials. Because of its characteristics that single-layer films do not have, it is more and more popular and used more and more in daily life. Therefore, Laminating single-layer films with different properties is an indispensable part of the composite film production process. The lamination of the film often requires heating the film, and the traditional lamination device will inevitably generate air bubbles during the preheating process, which will affect the quality of the composite film. In addition, different films need to be heated at different temperatures. If the temperature is too high, the film may be deformed and affect the bonding effect. If the film is in a suspended state after heating, the temperature of the film will be taken away because the air temperature is lower ...
