The motor 601 is arranged at the bottom of the support frame 5, the threaded rod 602 is rotatably arranged on the inner wall of the support frame 5 through a bearing, the sliding rod 603 is arranged on the inner wall of the support frame 5, the sliding plate 604 is threadedly connected to the threaded rod 602 through a threaded hole, and one end of the threaded rod 602 close to the motor 601 is connected to the output of the motor 601. The end is fixed, and the sliding plate 604 is slidably connected to the outer wall of the sliding rod 603 through a sliding hole. A circular groove 605 is opened on the surface of the sliding plate 604. A fan 10 is arranged on the surface of the sliding plate 604. The air outlet 613 is connected to the fan 10 through a connecting pipe 11. The air outlet 613 faces the side of the membrane head 3, and the air outlet 613 is arranged in an arc shape and adopts an arc structure to expand the coverage of the wind, which can not only make the wind blow more widely, but also effectively reduce the temperature of the film, making it easier to be clamped by the clamping member 610, which not only improves the production efficiency, but also ensures the stability and quality of the film processing.

[0024] The limiting rods 606 are equidistantly arranged on the surface of the sliding plate 604, the rotating disk 607 is rotatably arranged on the surface of the sliding plate 604 through a bearing, the arc grooves 608 are equidistantly arranged on the surface of the rotating disk 607, the inner wall of the arc grooves 608 is slidably connected to the outer wall of the limiting rod 606, the rotating rod 609 is rotatably arranged on the surface of the sliding plate 604 through a bearing, the clamping member 610 is arranged on the outer wall of the rotating rod 609, and the side of the clamping member 610 close to the membrane head 3 is provided with an anti-slip strip 12 for convenient clamping of the thin film The film, the clamping member 610 is provided with an anti-slip strip 12 on the side close to the film head 3, which improves the convenience and stability of clamping the film. The existence of the anti-slip strip 12 increases the friction between the clamping member 610 and the film, making the film more secure when clamped and not easy to slip. One end of the rotating bar 611 is rotatably set on the top of the clamping member 610 through an axle pin, and the other end of the rotating bar 611 is set on the inner wall of the rotating disk 607 through an axle pin. The position sensor 612 is set on the surface of the sliding plate 604.

[0025] It should be noted that the model of the position sensor 612 is TF1, which uses the inductive measurement principle and non-contact position detection with a free position mark. The measurement range is 1000mm, IP67, and the temperature range is -40℃-85℃. Electrical connection is a conventional technical means and will not be elaborated here.

[0026] A push plate 7 is provided on one side of the rotating disk 607, and a connecting rod 8 is rotatably provided on the surface of the push plate 7. An electric push rod 9 is provided on the surface of the sliding plate 604 located on one side of the push plate 7, and the extended end of the electric push rod 9 is rotatably connected to the connecting rod 8.

[0027] Working principle: When the film blowing machine 2 starts to blow the film out of the film head 3, the position of the film is detected by the position sensor 612 and the extended end of the electric push rod 9 is driven to extend. The extended end extends through the connecting rod 8 to push the push plate 7 to make the rotating disk 607 rotate counterclockwise. While the rotating disk 607 rotates, the rotating bar 611 pushes the clamping part 610 to rotate toward the grinding head, and then drives the fan 10 to rotate, and the wind is delivered to the air outlet 613 through the connecting pipe 11. The wind is blown toward the film, and the clamping part 610 rotates to clamp the film. After the clamping part 610 clamps the film, the fan 10 is turned off, and the motor 601 is driven forward. The output end of the motor 601 rotates, driving the threaded rod 602 to rotate, so that the sliding plate 604 slides upward along the outer wall of the sliding rod 603. When the sliding plate 604 slides to the traction position, the staff drives the protruding end of the electric push rod 9 to retract. When the protruding end of the electric push rod 9 retracts, it pulls the connecting rod 8. The connecting rod 8 rotates and pulls the push plate 7. At this time, the push plate 7 drives the rotating disk 607 to rotate clockwise. When the rotating disk 607 rotates, the rotating bar 611 pulls the clamping part 610 to rotate to the side away from the membrane head 3. Then the staff places the film at the traction position and performs the next step of operation, thereby realizing the pulling of the film.
