Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-4 As shown, the die-cutting roller structure of the film product of this utility model includes a fixed frame 1. The top of both sides of the inner wall of the fixed frame 1 is rotatably connected to a first rotating roller 2. Both ends of the first rotating roller 2 are nested with movable cutting rollers 4. Limiting grooves 13 are opened at the bottom of both sides of the inner wall of the fixed frame 1. Limiting sliders 20 are slidably connected inside the two limiting grooves 13. A second rotating roller 3 is rotatably connected between the two limiting sliders 20. Lifting components are provided inside the two limiting grooves 13. The lifting end of the lifting component is fixedly connected to the bottom end of the corresponding limiting slider 20.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the die-cutting roller structure of this utility model has a first T-shaped groove 6 on the surface of the first rotating roller 2. Two first T-shaped sliders are slidably connected inside the first T-shaped groove 6 and fixedly connected to the inner wall of the cutting roller 4. Positive and negative trapezoidal screws 7 are rotatably connected to both sides of the inner wall of the first T-shaped groove 6. The two ends of the positive and negative trapezoidal screws 7 are threadedly connected to the middle of the corresponding first T-shaped sliders. A rotating rod is rotatably connected to the side of the first T-shaped groove 6. The rotating rod is meshed with the end of the positive and negative trapezoidal screws 7 through a bevel gear 21.

[0020] Specifically, the positions of the two cutting rollers 4 in this roller structure are adjustable, which can adjust the position of the rollers according to the size of the film product being die-cut, thus improving the practicality of the rollers. At the same time, the second rotating roller 3 can adjust the distance between the first rotating roller 2 and the second rotating roller 3 by raising and lowering the lifting assembly, which can adapt to the driving of films of different thicknesses.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the die-cutting roller structure of this utility model has an open-type equipment box 5 fixedly installed on one side of the fixed frame 1. The end of the second rotating roller 3 extends into the inside of the equipment box 5 and is fixedly installed with a third pulley 22. A movable second pulley 16 is provided in the middle of one side of the inner wall of the equipment box 5. A drive shaft is rotatably connected to the top of one side of the inner wall of the equipment box 5. A first pulley 10 is fixedly provided at one end of the drive shaft. The first pulley 10, the second pulley 16 and the third pulley 22 are connected by a drive belt 11.

[0022] A second T-shaped groove 15 is provided in the middle of one side of the inner wall of the equipment box 5. A second T-shaped slider is slidably connected inside the second T-shaped groove 15. The second T-shaped slider is rotatably connected to the second pulley 16. An electric push rod 17 is fixedly installed on one side of the groove wall of the second T-shaped groove 15. The telescopic end of the electric push rod 17 is fixedly connected to the side of the second T-shaped slider.

[0023] A driven gear 9 is fixedly installed at the bottom of the drive shaft. A driving gear 8 is fixedly installed at the end of the first rotating roller 2 extending into the equipment box 5. A drive motor 12 is fixedly installed inside the equipment box 5. The output shaft of the drive motor 12 is fixedly connected to the end of the first rotating roller 2.

[0024] Specifically, the rotation of the first rotating roller 2 and the second rotating roller 3 can be achieved through the cooperation of the first pulley 10, the second pulley 16, the third pulley 22, the driving gear 8 and the driven gear 9.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the die-cutting roller structure of the film product of this utility model includes a lifting assembly comprising two top rods 14, a horizontal plate 18, and an electric hydraulic cylinder 19. The bottom of the fixed frame 1 is provided with an installation groove, and the horizontal plate 18 is nested inside the installation groove. Top rods 14 are fixedly installed on both sides of the top of the horizontal plate 18. The two top rods 14 extend into the interior of the limiting slide groove 13 and are fixedly connected to the bottom end of the corresponding limiting slider 20. The electric hydraulic cylinder 19 is fixedly installed at the bottom of the installation groove, and the telescopic end of the electric hydraulic cylinder 19 is fixedly connected to the center of the bottom end of the horizontal plate 18.

[0026] Specifically, the electric hydraulic cylinder 19 pushes the horizontal plate 18 upward, the upward movement of the horizontal plate 18 drives the top rod 14 to push the limit slider 20 upward, and the upward movement of the limit slider 20 drives the second rotating roller 3 upward.

[0027] In specific implementation, when using this roller cutter structure to die-cut film products, the distance between the two roller cutters is first manually adjusted according to the product being die-cut. The rotating rod drives the rotation of the positive and negative trapezoidal lead screws 7. The rotation of the positive and negative trapezoidal lead screws 7 causes the two first T-shaped sliders to move to the sides or towards the center. The movement of the first T-shaped sliders adjusts the position of the cutting roller cutter 4. Then, the distance between the second rotating roller 3 and the first rotating roller 2 is adjusted according to requirements. The electric hydraulic cylinder 19 is activated, pushing the horizontal plate 18 upwards. The upward movement of the transverse plate 18 causes the top rod 14 to rise, which in turn causes the limit slider 20 to rise. The limit slider 20 then causes the second rotating roller 3 to rise. As the second rotating roller 3 rises, the third pulley 22 also rises. To ensure the transmission effect between the first pulley 10, the second pulley 16, and the third pulley 22, the electric push rod 17 is activated. The extension and retraction of the electric push rod 17 pushes the second pulley 16 to move, thereby ensuring the transmission between the first pulley 10, the second pulley 16, and the third pulley 22.
