[0013] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0014] This invention achieves high pressing efficiency by using a moving component to shift the position of the heating component, a pressing component to press the multi-layer film, and a heating component to heat the bottom of the film. In use, a robotic arm places the film inside the carrier platform. The temperature controller is then activated to control the temperature of the first and second heating rods, thus heating the film. Next, the first motor is activated, driving the first threaded rod to rotate. This causes the fixed block to move the L-shaped sliding sleeve and the heating component to the right. Once at the designated position, the pressure regulating valve is opened, causing the cylinder to move the fixed platform and the upper contouring carrier downwards, pressing them against the film. When further adjustment is needed, the second motor is activated, causing the second threaded rod to rotate. This moves the positioning block, the mounting rod, the connecting column, and the upper contouring carrier downwards, further pressing the film. This design offers high pressing efficiency and easy adjustment, solving the problems of slow pressing speed and the inability to repeatedly adjust the pressing tightness in existing pressing mechanisms.

[0032] Step 2: After moving to the designated position, open the pressure regulating valve 22. Under the action of the pressure regulating valve 22, the cylinder 25 drives the fixed platform 295 and the upper contour carrier 26 to move downward and press against the film. When further adjustment is needed, turn on the second motor 291. Under the action of the second motor 291, the second threaded rod 294 rotates.
