Description

Technical Field

[0001] The present invention relates to the field of rotary die-cutting machines, and particularly to a rotary die-cutting machine laminating pressure adjustment and control device. Background Art

[0002] Rotary die-cutting machines can die-cut single-sided and double-sided self-adhesive labels, protective films, gaskets, dust-proof nets, copper and aluminum foils, etc. of various shapes. These products are widely used in the front and back covers, windows, displays, microphones, speakers, keyboards, batteries, etc. of electronic products such as mobile phones, laptops, PDAs, digital cameras, and audio systems. However, when producing these products, the products are attached to another layer through lamination by the die-cutting machine to complete the production. However, during production, people adjust the distance between the rotating roller and the fixed roller to achieve perfect lamination of the products. The existing adjustment methods are all achieved by people rotating the knob that controls the movement of the fixed roller to adjust the distance between the rotating roller and the fixed roller. However, people cannot grasp the lamination pressure between the rotating roller and the fixed roller, so it takes a long time to adjust, and the operation is cumbersome. When changing different products, people need to re-adjust the distance between the rotating roller and the fixed roller according to the lamination pressure of different products, which reduces the production efficiency of the products.

[0003] Therefore, it is necessary to provide a new rotary die-cutting machine laminating pressure adjustment and control device to solve the above technical problems. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a rotary die-cutting machine laminating pressure adjustment and control device that can automatically adjust the pressure between the rotating roller and the fixed roller.

The device further comprises an adjustment device, a pneumatic sensor and a controller. The adjustment devices are symmetrically and fixedly installed at both ends of the base. The adjustment device is used for lifting the fixed roller. The adjustment device comprises an installation groove, an installation frame, a cylinder fixing cylinder, an installation plate, a second motor and a first gear. The installation grooves are symmetrically formed at the top of both ends of the base. The installation frames are fixedly installed at the top positions corresponding to the installation grooves at both ends of the base through bolts.

Before debugging the device, people preset the pressure between the rotating roller and the fixed roller used for producing different products by the pneumatic sensor. When debugging the pressure between the rotating roller and the fixed roller, only the precise operation position of the adjustment device needs to be controlled through the controller.
