[0010] Optionally, a gas telescopic rod is hingedly provided at the bottom of the metal tooling, and the other end of the gas telescopic rod is hingedly provided at the middle bottom position of the support structure below the movable frame.

[0013] Beneficial Effects

[0014] The oblique clamps according to the embodiments of the present invention provide a one-way pulling conveying structure, and the movable frame drives the oblique clamps to move forward. While the front angle of the oblique clamps contacts the rear guide wheel, the two groups of oblique clamps are separated by the external pressure-bearing guide of the rear guide wheel, and then the oblique clamps are moved to the outside of the guide bar and slide against the outside of the guide bar. During this process, the oblique clamps do not contact the film material. When the oblique clamps are separated from the guide bar, the two groups of oblique clamps cooperate with the springs on the outside of the spring rod B to automatically reset, and then clamp the two ends of the film material on the front side, thereby realizing one-way pulling conveying. The control effect is stable, and the film peeling phenomenon during the conveying process can be avoided, thereby ensuring safe conveying.

[0015] In addition, after the frame cutter fits the metal tooling, the moving frame will still move forward a part, and then the gas telescopic rod will automatically adapt. When the gas telescopic rod contracts, the air in the gas telescopic rod is discharged through the exhaust one-way valve, and then the gas telescopic rod remains in a contracted state, ensuring that the frame cutter and the metal tooling are directly closed during the forward movement of the moving frame, and the frame cutter and the metal tooling will not be separated with delay during the backward movement of the moving frame.

[0016] In addition, the setting of the fixed air valve provides a reset guarantee effect. When the moving frame moves backward, the air telescopic rod is in a retracted state. When the moving frame starts to move backward, the air telescopic rod directly separates the metal tooling and the frame cutter, ensuring that the film material delivery is not affected at the first time. Until the fixed air valve contacts the trigger plate, the fixed air valve is automatically triggered to open, and the outside air enters the air telescopic rod to ensure that the air telescopic rod can automatically reset.
