Problems solved by technology
[0002] In existing PET and OPP film dual-purpose laser molding presses, since the position of the preheating roller in the OPP film traction roller system is fixed, the distance between the preheating roller and the plate roller in the embossing system is narrow. It is very difficult to carry out the plate-mounting operation. At the same time, when producing OPP film pressed products, because the coating surface of the OPP film is covered on the preheating roller and the stretching tension of the film is fixed and cannot be adjusted, while the coating The cladding directly affects the angle and distance of the film between the preheating roller and the plate roller in the embossing system. In the actual production process, the thickness and tension of the raw materials provided by each manufacturer are different. It is different from the demand for tension, which causes many raw materials to be unusable and quality problems of finished products

The utility model relates to a dual-purpose laser molding machine for PET and OPP films, which belongs to the technical field of laser molding machines. It includes an unwinding system, a front embossing system, a post embossing system, and a winding system, and is characterized in that the preheating roller in the OPP film traction roller system is a movable preheating roller. In the present invention, the preheating roller in the OPP film traction roller system in the original PET and OPP film dual-purpose laser molding machine is changed to a movable preheating roller, and the OPP film is adjusted in the preheating state by adjusting the position of the preheating roller. The covering surface on the roller and the angle, distance and stretching length of the film between the preheating roller and the plate roller in the embossing system can realize the requirements for embossing angle, temperature and tension of different quality OPP films. At the same time, in the process of attaching plates to the plate rolls in the embossing system, the distance between the plate rolls and the preheating rolls in the embossing system is increased by adjusting the position of the mobile preheating roll, making the plate attaching operation easier .
