Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 5 shown, the present utility model provides a cutting device for a film slitting machine, including a workbench 1, a connecting frame 2 is fixed on the right side of the workbench 1, a rotating groove is opened at the top of the connecting frame 2, a mounting rod 3 is rotatably connected to the top of the connecting frame 2, a film reel 4 is sleeved on the outer wall of the mounting rod 3, and a limiting mechanism 7 is installed on the inner wall of the workbench 1.

[0024] Adopting the above scheme: by sleeving the film reel 4 on the outer wall of the mounting rod 3, since the mounting rod 3 can rotate at the top of the connecting frame 2, when the mounting rod 3 rotates, it can also drive the film reel 4 to rotate, so that the film sleeved on the film reel 4 can be guided by the low guide roller 5 and the high guide roller 6, so that the position of the film can be guided when rotating, and the film can smoothly enter the next process.

[0025] As Figure 1 and Figures 3 to 5As shown, the limiting mechanism 7 includes an upper limiting block 701, a lower limiting block 702 and a hydraulic rod 703. The upper limiting block 701 is fixed to the inner wall of the workbench 1, and the lower limiting block 702 is fixed to the inner wall of the workbench 1. A chute is provided at the top end of the lower limiting block 702. The chutes provided at the top end of the lower limiting block 702 and the bottom end of the upper limiting block 701 are in two groups, and two groups of first mounting blocks 704 and second mounting blocks 706 are also provided and are slidably connected to the slots of the lower limiting block 702 and the upper limiting block 701. The first mounting block 704 is slidably connected to the top end of the lower limiting block 702, and a hydraulic rod 703 is fixed to the front end of the first mounting block 704. A chute is provided at the bottom end of the upper limiting block 701. The second mounting block 706 is slidably connected to the bottom end of the upper limiting block 701. A limiting roller 705 is rotatably connected to the top end of the first mounting block 704, and the second mounting block 706 is rotatably connected to the top end of the limiting roller 705. A hydraulic rod 703 is fixed to the front end of the first mounting block 704. A chute is provided at the bottom end of the upper limiting block 701. The second mounting block 706 is slidably connected to the bottom end of the upper limiting block 701.

[0026] With the above solution: By providing components such as the upper limiting block 701, the lower limiting block 702 and the hydraulic rod 703, the film can enter the cavity between the upper limiting block 701 and the lower limiting block 702 after passing through the pre-guiding, and the up and down positions of the film during transmission can be limited to prevent its position from shifting and affecting the subsequent cutting position. Moreover, through the shapes of the upper limiting block 701 and the lower limiting block 702, the film can be better guided in and discharged. And by arranging the hydraulic rod 703, the first mounting block 704, the limiting roller 705 and the second mounting block 706 inside the upper limiting block 701 and the lower limiting block 702, the first mounting block 704 and the second mounting block 706 can slide inside the lower limiting block 702 and the upper limiting block 701, and a limiting roller 705 is rotatably connected between the first mounting block 704 and the second mounting block 706. When the film contacts the limiting roller 705, the limiting roller 705 will rotate to limit the front and back positions of the film currently in the inner cavities of the upper limiting block 701 and the lower limiting block 702, preventing it from swaying back and forth and affecting the subsequent cutting effect. In order to adapt to films of different widths, the arranged hydraulic rod 703 can push the first mounting block 704, so as to drive the overall positions of the first mounting block 704, the limiting roller 705 and the second mounting block 706 to move, so as to achieve the purpose of adjusting the width of the two limiting components.

[0027] As Figures 1 to 2As shown in the figure, a low guide roller 5 is installed on the inner wall of the workbench 1, and a high guide roller 6 is arranged on the inner wall of the workbench 1. The height of the low guide roller 5 is lower than that of the high guide roller 6. Two groups of mounting seats 8 are fixed at the front and rear ends of the inner wall of the workbench 1. Two groups of drive rollers 9 are slidably connected to the inner wall of the mounting seat 8, and a height adjustment knob 10 is arranged at the top of the mounting seat 8.

[0028] With the above solution: By installing two groups of drive rollers 9 between the two groups of mounting seats 8, the position of the film can be further guided. By the height adjustment knob 10, the height of the drive roller 9 can be rotated to meet the result of guiding the film under different conditions.

[0029] As Figures 1 to 2 shown in the figure, two groups of tool holders 11 are fixed at the front and rear ends of the inner wall of the workbench 1. A tool holder 12 is slidably connected to the inner wall of the tool holder 11. A cutting blade 13 is fixedly connected to the bottom end of the tool holder 12. A discharge chute 14 is installed at the left end of the workbench 1. The design of the discharge chute 14 is that the opening is inclined upwards at 45°.

[0030] With the above solution: The position of the film is guided to the bottom end of the cutting blade 13 by the drive roller 9. The tool holder 12 is slidably connected to the inner cavity of the tool holder 11, and the sliding position is controlled electrically. The system can automatically identify that after the film reaches the appropriate length, it controls the tool holder 11 to drop, so that the cutting blade 13 contacts the film, cuts the film, and makes the cut film fall onto the lower discharge chute 14, and the discharge chute 14 collects and arranges the cut film.

[0031] The working principle and usage process of the present utility model: By sleeving the film reel 4 on the outer wall of the mounting rod 3, since the mounting rod 3 can rotate at the top of the connecting frame 2, when the mounting rod 3 rotates, it can also drive the film reel 4 to rotate, so that the film sleeved on the film reel 4 can be guided by the low guide roller 5 and the high guide roller 6. By setting components such as the upper limit block 701, the lower limit block 702, and the hydraulic rod 703, the film can enter the cavity between the upper limit block 701 and the lower limit block 702 after pre-guidance, and the up and down positions of the film during transmission can be limited to prevent its position from shifting and affecting the subsequent cutting position. And through the shapes of the upper limit block 701 and the lower limit block 702, the film can be better guided in and discharged.
