The PET film is placed on the heat conducting block, and the inside of the central pipe is evacuated to a negative pressure through a suction hose, so that the main suction groove and the branch suction grooves arranged on the rotating suction head are evacuated to a negative pressure. Subsequently, the servo motor drives the first bevel gear to rotate through the second bevel gear, thereby driving the rotating suction head fixedly connected to the central pipe to rotate, so as to rotate the PET film. The heating pipe heats the heat conducting block to facilitate the stretching operation of the PET film. The device has a simple structure, can automatically rotate the PET film, and effectively improves the production efficiency.

[0002] PET film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability. It can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, optical grade mirror surface protection and other fields. In the new energy power battery industry, PET film is needed for electrical insulation protection, while traditional PET film is mostly directly pulled out by traction rollers for unidirectional stretching. After unidirectional stretching, the mechanical properties of the PET film in the stretching direction are good. When used in complex environments, creases and other problems that affect the insulation performance may occur. Therefore, users often stretch the PET film again after purchasing it to meet the mechanical properties. Since there is no special equipment on the market, manual stretching is mostly used, and the direction of the PET is also manually adjusted during stretching, resulting in low efficiency. In view of the above defects, it is necessary to design a PET film preheating rotation mechanism. Summary of the invention
