A support frame 3 is fixedly installed at one end of the top of the base plate 1, and a winding frame 9 is rotatably installed on one side of the support frame 3. Pressure adjustment components are provided at both ends inside the film-tearing box 11. In the production process of stamped parts, it is necessary to remove the protective film from the surface of the steel coil. When the steel coil in the circular resting cavity 10 enters the film-tearing box 11, it will be subjected to double-sided squeezing force from the pressure adjustment component, which will straighten the steel coil and reduce the impact of the bent steel coil on the film-tearing effect. With the rotation of the winding frame 9, the protective film can be wound up, so that the protective film is separated from the steel coil and the waste protective film is collected. In this process, the time and labor intensity of manual operation are reduced, and the film-tearing efficiency is significantly improved.
[0031] Specifically, the pressure adjustment assembly includes mounting grooves on both sides of the inner wall of the film-tearing box 11. A screw 13 is rotatably connected inside one mounting groove, and a fixing rod 16 is fixedly connected inside the other mounting groove. The fixing rod 16 ensures greater stability of the pressure roller a14 during adjustment, guaranteeing effective pressure on the steel coil. A threaded block 21 is threadedly connected to the outer side of the screw 13. The pressure adjustment assembly also includes a limiting rod 17 slidably connected to the outer side of the fixing rod 16. The pressure roller a14 is rotatably mounted between the limiting rod 17 and the threaded block 21. Rotation of the screw 13 causes the threaded block 21 to slide within the mounting groove, thereby adjusting the pressure according to the... The thickness of the steel coil is used to adjust the pressing position of the pressure roller a14 to improve the adaptability of the device and enable wider industrial applications. Inside the film-tearing box 11 and below the pressure roller a14, the pressure roller b15 is rotatably installed. Inside the circular resting cavity 10, a clamping assembly is provided. The clamping assembly includes four sliding grooves opened inside the relaxation roller 8. Each sliding groove is fixedly connected to a limit rod 17. A spring 18 is sleeved on the outside of each limit rod 17. Through the reaction force of the spring 18, the slider on the limit rod 17 can be pushed to move. With the help of the connecting rod 19, the four abutment plates 20 are gradually unfolded, thereby achieving the purpose of fixing steel coils of different sizes.
[0032] Specifically, the clamping assembly also includes sliders slidably connected to both ends of the outer side of the limiting rod 17. A connecting rod 19 is rotatably connected to the outer side of each slider. A contact plate 20 is provided between the two connecting rods 19. The end of the connecting rod 19 furthest from the slider is rotatably connected to the contact plate 20. A spring 18 is provided between the slider and the inner wall of the groove. A drive motor is fixedly installed on the outer side of the support frame 3. The output shaft of the drive motor is fixedly connected to the rotation shaft of the winding frame 9. The rotation of the output shaft of the drive motor drives the winding frame 9 to rotate, thereby enabling the winding operation of the steel coil. Servo motors a12 are fixedly installed at both ends of the top of the film-tearing box 11. The output shaft of the servo motor a12 extends into the interior of the mounting groove and is fixedly connected to the corresponding screw 13.

The arrangement of the guide rollers b6 and c7 provides directional guidance for the protective film.
[0033] Working principle: First, during the production of stamped parts, the protective film on the surface of the steel coil needs to be removed. The steel coil can be fixed using a clamping assembly, as follows: The reaction force of spring 18 pushes the slider on the limit rod 17 to move, and with the help of connecting rod 19, the four contact plates 20 gradually unfold, thus achieving the purpose of fixing steel coils of different sizes. Then, the servo motor a12 is started, and the rotation of screw 13 drives the threaded block 21 to slide in the mounting groove. This allows the pressure position of the pressure roller a14 to be adjusted according to the thickness of the steel coil, and the protective film on the steel coil is then sequentially applied... Guide rollers b6 and c7 connect the coil to the take-up frame 9. Then, the traction machine at the front of the device and the drive motor inside the device are started, causing the steel coil to rotate continuously. When the steel coil in the circular resting cavity 10 enters the film-tearing box 11, it is subjected to double-sided squeezing force from the pressure adjustment component, which straightens the steel coil to reduce the impact of bent steel coil on the film-tearing effect. With the rotation of the take-up frame 9, the protective film can be wound up, separating the protective film from the steel coil and collecting the waste protective film. In this process, the time and labor intensity of manual operation are reduced, and the film-tearing efficiency is significantly improved.
