Film synchronous embossing device

Abstract

The invention relates to the field of film synchronous embossing and particularly relates to a film synchronous embossing device. The device comprises a first bracket, a rubber roller arranged on the first bracket, a second bracket and an embossing roller arranged on the second bracket. The surface of the embossing roller is provided with uneven patterns the same to the film patterns. The rubber roller and the embossing roller are respectively connected to a first motor and a second motor. The first motor and the second motor respectively control a rotation direction and a rotation rate of the rubber roller and the embossing roller. The embossing roller can move relative to the rubber roller on the plane along front, rear, left and right directions. The device is free of a single driven embossing roller and a passively driven rubber roller of the conventional embossing device and drives the embossing roller and the rubber roller through the different driving devices so that the relative position of the embossing roller and a film can be adjusted at an embossing position at any time and thus the embossing patterns are corresponding to the printing patterns and the adjustment of the materials having high waste in the traditional process is avoided.

Description

【Technical field】 [0001] The invention relates to the field of film synchronous embossing, in particular to a film synchronous embossing device. 【Background technique】 [0002] 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 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. One of the biggest disadvantages of this design is that if the printed pattern and embossing The lines of the rollers are not aligned. When adjustments are needed, the printing speed of the printing roller must be accelerated or slowed down. There is a long distan...

Problems solved by technology

However, 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. One of the biggest disadvantages of this design is that if the printed pattern and embossing The lines of the rollers are not aligned. When adjustments are needed, the printing speed of the printing roller must be accelerated or slowed down. There is a long distance between the printing roller and the embossing roller, so the speed of the two must be consistent. , during the adjustment period, a very long amount of material needs to be wasted, and it needs to be adjusted to be completely consistent and requires 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
