a printing press

【Technical field】

The utility model relates to a printing machine.

【Background technique】

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 than the film temperature, so that the best bonding effect cannot be achieved.

The embossing process is a process that uses a concave-convex mold to plastically deform the printed matter under a certain pressure, thereby artistically processing the surface of the printed matter. Usually the product is printed and embossed simultaneously to ensure a one-to-one correspondence between the printed pattern and the embossed pattern. However, in the production process, the film needs to be heated after printing to start embossing. If the distance between the embossing device and the printing device is too far, the film will be deformed due to stretching, and the printed pattern and the embossed pattern will not be aligned. . Therefore, it is necessary to reduce the distance between printing and embossing as much as possible. 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.

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, an extremely 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 received is relatively large, and the film will be deformed by the tensile force during this process, making it more difficult to achieve the correspondence between the printed pattern and the embossed pattern.

This method has changed the traditional way of setting the embossing assembly and printing assembly horizontally, shortening the length of the film between the embossing assembly 400 and the printing cylinder 480; if the length between the embossing assembly 400 and the printing cylinder 480 If it is too long, the film will be deformed due to excessive tension, which will affect the precise matching of the printed pattern and the embossed pattern. The traditional embossing assembly and printing assembly are arranged horizontally, and the length of the film between the embossing assembly and the printing assembly cannot be shortened because the volume of the embossing assembly itself is too large. Perfectly solved the above problems. 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, an extremely 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 this embodiment, the first motor 640 and the second motor 641 separately control the rotation direction and the rotation speed of the rubber roller 611 and the embossing roller 621 respectively, abandoning the method of separately driving the embossing roller and passively driving the rubber roller in the traditional embossing device, The embossing roller and the rubber roller are driven by different driving devices, so that the relative position of the embossing roller and the film can be adjusted at any time at the embossing position, so as to realize the correspondence between the embossing pattern and the printing pattern, without the need for traditional process Mid-adjustment wastes a lot of material. If the rubber roller is passively rotated, adjusting the rotation of the embossing roller will also adjust the rotation of the rubber roller at the same time, which fails to achieve the purpose of adjusting the embossed pattern to correspond to the printed pattern. Moreover, the rotation speed of the embossing roller in the utility model is no longer affected by the speed of the embossing device synchronously, and the embossing roller maintains a certain rotation speed. As long as the printing speed is equal to or slightly faster, the embossing pattern will not be affected. The alignment with the printed pattern, unlike in traditional embossing, the embossing roller also needs to provide the tension for the film to advance, so that the film will not be deformed and the product quality will be better.

The third rubber roller 332 and the second preheating roller 322 cooperate to squeeze the air between the second preheating roller 322 and the second film layer to achieve the same effect as above. Since the second film layer has a small floating position after preheating, it is better to put the second film layer in close contact with the preheating laminating roller 321 during preheating lamination, and place the first film layer on the outer position . When the winding of the first film layer is not completed, the first film layer needs to be placed on the bonding place between each roller.
