Five-shaft high-speed laminating machine and control method

Abstract

The invention discloses a five-shaft high-speed laminating machine and a control method. The laminating machine comprises a laminating device and a control board. The control board comprises a touch screen, a PLC and a communication board. The PLC is connected with a membrane buffer device, a membrane releasing shaft operation module, a laminating shaft operation module, a hot roller shaft operation module and a membrane collection shaft operation module of the laminating device. The communication board is connected with a winding servo tension speed module to control the winding tension and speed and an analog output module to control membrane releasing magnetic powder, winding magnetic powder and heating. According to the laminating machine and the control method, temperature can be effectively controlled; the problems of overheating and insufficient heating on the quality of laminating are solved; the quality and speed of laminating are improved; and the laminating speed is up to 120M per minute.

Description

technical field [0001] The invention belongs to the technical field of laminating machines, in particular to a high-speed laminating machine and a control method thereof. Background technique [0002] The laminating machine can be divided into two categories: instant coating laminating machine and pre-coating laminating machine. It is a special equipment for paper and film. The ready-to-coat laminating machine includes three parts: gluing, drying, and hot pressing. It has a wide range of applications and stable and reliable processing performance. It is currently the most widely used laminating equipment in China. Pre-coating laminating machine, without gluing and drying parts, small size, low cost, flexible and convenient operation, not only suitable for lamination processing of large batches of printed matter, but also suitable for lamination of small batches of scattered printed matter such as automated desktop office systems processing. [0003] For example, patent ap...

AI Technical Summary

Problems solved by technology

[0004] Existing laminating machines use double rollers at the same speed and are controlled by a servo. When the laminating quality is not ideal, it cannot be adjusted.

During operation, the paper film will take away the heat through the hot roller, so that the temperature of the hot roller will drop. The faster the operation, the faster the temperature will drop, and the higher the heating intensity will be to keep the temperature of the hot roller constant. On the contrary, if the heating intensity is very low at low speed Strong, it is easy to overheat (because of the slow response of the temperature sensor), at this time, the heating intensity should be small to avoid overheating, overheating and insufficient heating have a great impact on the quality of the coating

Therefore, there are defects such as difficult adjustment, unreasonable temperature control, and low film quality.
