[0004] However, the current fixed-length slitting machines used in the production of tipping paper have the following defects: usually during the cutting process, the two sides of the tipping paper are not flat enough, causing the cutter to deviate, produce rough edges or break. In addition, the force is uneven when the cutter contacts the tipping paper, resulting in excessive local force on the cutter blade, which reduces the cutter replacement cycle and increases the wear and tear cost of the cutter.

[0005] To address this issue, we propose a fixed-length slitting machine for cork paper production. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please refer to Figures 1-2. This utility model provides a technical solution: a fixed-length slitting machine for producing cork paper, including a workbench 1. A portal frame 2 is fixedly connected to one side of the top surface of the workbench 1. A movable block 21 is arranged between the inner walls of the portal frame 2. A cutter 22 is fixedly installed on the bottom surface of the movable block 21. A first rotating frame 32 and a second rotating frame 33 are arranged crosswise on both sides of the movable block 21. A mounting frame 3 is fixedly connected to the ends of the first rotating frame 32 and the second rotating frame 33. A pressure roller 31 is rotatably arranged between the inner walls of the mounting frame 3. The pressure roller 31 is elastic. The two pressure rollers 31 are located at the cutter. On both sides of 22; the moving block 21 moves, driving the cutter 22 to move. The cutter 22 moves downward to cut the tipping paper. During the movement of the moving block 21, it also drives the first rotating frame 32 and the second rotating frame 33 on both sides to move. The movement of the first rotating frame 32 and the second rotating frame 33 drives the mounting frame 3 and the pressure roller 31 at the bottom to move. When the pressure roller 31 contacts the tipping paper, it flattens and unfolds the tipping paper, and at the same time, it further fixes the tipping paper. Due to the elastic setting of the pressure roller 31, it achieves uniform pressure through elastic deformation, which is convenient to adapt to the thickness of the tipping paper.

[0028] A movable frame 4 is slidably mounted on the top surface of the workbench 1, and a pressure plate 41 is slidably mounted between the inner walls of the movable frame 4. When it is necessary to fix the cork paper, the pressure plate 41 is moved, and the pressure plate 41 moves between the inner walls of the movable frame 4. The cooperation between the movable frame 4 and the workbench 1 presses and fixes the cork paper.

[0029] Example 2:

[0030] Please refer to Figures 1-3, which show the second embodiment of this utility model. This embodiment is based on the previous embodiment. The movable block 21 is fixedly connected to two cylindrical rods 35 on both sides. The cylindrical rods 35 are rotatably connected to the first rotating frame 32 and the second rotating frame 33, respectively. Two tension springs 34 are provided on the top of the movable block 21. The tension springs 34 are fixedly connected to the side walls of the first rotating frame 32 and the second rotating frame 33, respectively. When the movable block 21 moves, it drives the cylindrical rods 35 on it to move. The movement of the cylindrical rods 35 drives the first rotating frame 32 and the second rotating frame 33 to move. The movement of the first rotating frame 32 and the second rotating frame 33 drives the mounting frame 3 and the pressure roller 31 at the bottom to move. When the pressure roller 31 contacts the tipping paper, the mounting frame 3 and the pressure roller 31 extend outward to both sides. At this time, the top of the first rotating frame 32 and the second rotating frame 33 extends outward to both sides, and the first rotating frame 32 and the second rotating frame 33 pull the tension springs 34 open.

[0031] The workbench 1 has sliding grooves 44 on both sides, and a slider 43 is slidably connected inside the sliding groove 44. The top surface of the slider 43 is fixedly connected to the bottom of the moving frame 4. Multiple insertion holes 45 are evenly opened inside the sliding groove 44. A rod 46 is provided on one side of the slider 43. The rod 46 passes through the slider 43 and is inserted into any insertion hole 45. When the position of the moving frame 4 needs to be adjusted, the rod 46 is pulled out and the moving frame 4 is moved. The movement of the moving frame 4 causes the slider 43 to move in the sliding groove 44. After it is moved to the appropriate position, the slider 43 is fixed to the insertion hole 45 by the rod 46.

[0032] A lead screw 42 is provided in the middle of the movable frame 4, and a wire hole is opened in the middle of the movable frame 4. The lead screw 42 is connected to the wire hole and passes through the movable frame 4 and is rotatably connected to the top surface of the pressure plate 41. When it is necessary to fix the tipping paper, rotate the lead screw 42, and the lead screw 42 drives the pressure plate 41 to move. The cooperation between the pressure plate 41 and the worktable 1 clamps and fixes the tipping paper.

[0033] An electric cylinder 23 is fixedly connected to the top surface of the portal frame 2. The piston rod of the electric cylinder 23 passes through the portal frame 2 and is fixedly connected to the top surface of the moving block 21. When cutting, the electric cylinder 23 is turned on, and the electric cylinder 23 drives the moving block 21 to move through the piston rod. The movement of the moving block 21 drives the cutter 22 to complete the subsequent cutting work.

[0034] The top surface of the workbench 1 is provided with a cutting groove 11, which is located directly below the cutter 22. The top surface of the gantry frame 2 is provided with a scale line 12 near the movable frame 4, which is perpendicular to the movable frame 4. During production, the position of the movable frame 4 can be adjusted according to the scale on the scale line 12. The cutting groove 11 provides assistance for the cutter 22 to cut.

[0035] Example 3:

[0036] Please refer to Figures 1-3, which show the third embodiment of this utility model. This embodiment is based on the two embodiments described above. In use, according to production needs, the position of the moving frame 4 is adjusted according to the scale on the scale line 12. Moving the moving frame 4 causes the slider 43 to move within the slide groove 44. After moving to the appropriate position, the insert rod 46 is used to fix the slider 43 to the corresponding insertion hole 45. Then, the tipping paper is conveyed to the area below the moving frame 4 through the feeding structure. The lead screw 42 is rotated, causing the pressure plate 41 to move. The cooperation between the pressure plate 41 and the worktable 1 fixes one end of the tipping paper. The cutting process begins with the activation of the electric cylinder 23. The electric cylinder 23, via its piston rod, moves the moving block 21, which in turn moves the cutter 22. The cutter 22, in conjunction with the cutting groove 11, cuts the tipping paper. Simultaneously, the moving block 21 moves the cylindrical rod 35, which in turn moves the first rotating frame 32 and the second rotating frame 33. This movement of the first and second rotating frames 32 and 33 then moves the mounting frame 3 and the pressure roller 31 at the bottom. Once the pressure roller 31 contacts the tipping paper, the mounting frame 3 and the pressure roller 31 extend outwards to both sides. At this point, the first and second rotating frames 32 and 33... The paper unfolds to both sides, the first rotating frame 32 and the second rotating frame 33 pull the tension spring 34 open, and the pressure roller 31 flattens and unfolds the tipping paper, while further fixing the tipping paper. After the cutting work is completed, the electric cylinder 23 returns the moving block 21 to its original position through the piston rod, and the tension spring 34 uses its pulling force to return the first rotating frame 32 and the second rotating frame 33 to their original positions. The mounting frame 3 and the pressure roller 31 return to their initial positions. In this utility model, during the cutting of tipping paper, the cooperation between the mounting frame 3 and the pressure roller 31 and the components can flatten the two sides of the tipping paper before cutting, avoiding the cutter 22 from deviating due to uneven paper. To address issues such as shifting, rough edges, or breakage, the elastic characteristics of the pressure roller 31 in this invention allow it to adapt to the undulations of the paper surface, facilitating the application of uniform pressure to the contact surface of the tipping paper. Furthermore, after the pressure roller 31 flattens the tipping paper, the cutter 22 experiences uniform force when in contact with it, reducing excessive localized force on the cutter 22 blade due to paper warping, extending the cutter 22 replacement cycle, and lowering the wear and tear costs of the cutter 22. In this invention, the movable frame 4 and pressure plate 41 can move along the sliding grooves 44 on both sides of the worktable 1, facilitating the adaptation of tipping paper rolls of different lengths. No hardware replacement is required; the fixed length can be achieved through manual adjustment, making cutting convenient.
