[0002] Polyester film is a kind of polymer plastic film, which is more and more favored by consumers because of its excellent comprehensive performance. It is a colorless, transparent, glossy film with excellent performance, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance, good air tightness and freshness preservation. It is one of the commonly used barrier composite film substrates with good printability. Polyester film is often used in the outer layer of flexible packaging, and is made into packaging for various common foods, beverages, medicines and daily chemicals in life. It also has certain applications in photovoltaics, such as for the protection of the surface of photovoltaic backplanes. This type of film generally adopts light Compared with the traditional polyester film used in life, the photovoltaic polyester film has better protection strength such as wear resistance and heat resistance. The traditional process of making photovoltaic polyester film is generally: batching, mixing, extrusion, heating, plasticizing, casting, longitudinal stretching, transverse stretching and traction shaping and trimming. Through this process, a complete polyester film can be formed to achieve the manufacture of polyester film. In this process, transverse stretching and traction shaping and trimming are particularly important. Generally, transverse stretching and traction shaping and trimming are set in the same equipment for direct production of film. The trimming mechanism in the existing transverse stretching device is as follows:

[0003] For example, the patent publication number CN211843183U discloses a press edge shear roller mechanism for an optical grade polyester film transverse pulling device, including a frame, the right end of the frame is vertically fixedly connected to a guide roller frame, the guide roller frame is movably connected to a guide roller, the left side of the frame is horizontally fixedly connected to the right with a cylinder, the right end of the piston rod of the cylinder is fixedly connected to the left side of a rectangular vertical pole, and the front side wall of the rectangular vertical pole is engraved with distance scale lines from the middle to both sides in sequence. The utility model drives the first threaded screw and the second threaded screw to rotate according to the width requirement of the edge of the cutting film strip, and drives the two horizontal plates to rotate in the opposite direction or oppositely respectively, so that each adjustment can ensure that the cutting blade docks in the cutting groove of the guide roller, and then the cylinder drives the two pressing wheels to press the film strip, and at this time, the cutting blade and the cutting groove cooperate to press the edge when the film strip is transmitted, which is convenient and quick, and the adjustment is very convenient, avoiding the problem of complex structure and high cost in the prior art.

[0004] The utility model mainly utilizes the operation of the motor to drive the threaded rod to rotate, and the threaded rod drives the cutting blade to move to a position opposite to the cutting groove during the rotation, so that the cutting blade contacts the cutting groove, thereby processing the polyester film. Although the polyester film can be processed in this way, since the cutting groove is opened on the guide roller and the opening position is fixed, the edge shearing can only cut polyester film of one size. If different sizes of cutting are required, the device cannot cut polyester films of different sizes. At the same time, if multiple cutting grooves are set, although polyester films of different sizes can be cut, when the cutting size of the polyester film is just located between two adjacent cutting grooves, the device cannot cut the polyester film, which leads to poor applicability.
