The instant 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 a widely used laminating equipment in China. The pre-coating laminating machine has no gluing and drying parts, is small in size, low in cost, and is flexible and convenient to operate. It is not only suitable for laminating large quantities of printed materials, but also suitable for laminating small quantities and scattered printed materials such as automated desktop office systems. It has great development prospects.

[0003] In the prior art, the fully automatic and efficient laminating machine proposed in the patent with publication number CN205311024U includes a paper feeding mechanism, a laminating mechanism, a winding mechanism, a frame, and a controller; the winding mechanism includes a winding roller and a winding motor, and the output shaft of the winding motor is connected to the winding roller; a laminating mechanism is arranged on one side of the paper feeding mechanism, and a winding mechanism is arranged on one side of the laminating mechanism, and the laminating mechanism and the winding mechanism are arranged on the frame; the paper feeding mechanism includes a paper frame, a paper roll roller, and a paper feeding roller, a paper roll roller is fixed on the paper frame, and a pair of paper feeding rollers are arranged on one side of the paper roll roller; the laminating mechanism includes a film roller, a film adjustment device, a glue roller, a heating roller, and a photoelectric sensor.
