Technical Field

[0001] This utility model relates to the field of cutting and packaging tools, and in particular to an adjustable multi-functional cutting and packaging tool. Background Technology

[0002] In the modern packaging industry, the product cutting and packaging process is crucial. Cutting and packaging operations are widely used in many fields such as food, pharmaceuticals, and daily chemicals. Different products have different requirements for cutting packaging materials, such as the material, thickness, cutting width, and blade replacement frequency. This necessitates a cutting tool that can adapt to various cutting needs to improve the efficiency and quality of cutting and packaging and reduce production costs. Against this backdrop, adjustable multi-functional cutting tools for cutting and packaging have emerged, which are of great significance for improving the overall production level of the packaging industry.

[0003] Currently, traditional slitting and packaging knives have many shortcomings in practical applications. Most existing knives use a fixed installation method for the blades, and when the blades wear out, the entire knife often needs to be replaced. This not only increases the cost of use but also wastes a lot of time and resources. The reason for this problem is that the connection structure between the blade and the knife body is not designed reasonably and lacks a convenient disassembly and installation mechanism. Therefore, in order to address the problem that the entire knife often needs to be replaced when the blades wear out, an adjustable multi-functional slitting and packaging knife is needed to solve the above problems. Utility Model Content

[0004] To address the problem in existing technologies where the entire cutting tool often needs to be replaced when the blade wears out, this application provides an adjustable multi-functional cutting tool for slitting and packaging. The blade can be easily removed from the shaft or a new blade can be installed by turning a bolt. When the blade wears out or needs to be replaced with a different size blade to meet different slitting requirements, there is no need to replace the entire cutting tool. The position between the two blades can be easily adjusted with the help of a two-way lead screw, slider, knob and related limiting components.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable multi-functional cutting and packaging knife includes a support frame. A limiting roller is rotatably connected to the inner wall of the support frame.

The bidirectional lead screw is rotatably connected to the inner wall of the support frame. A knob is fixedly connected to the right end of the bidirectional lead screw. The right end of the support frame is connected to the knob via a limiting assembly.

[0007] As a further improvement of this utility model, the linkage component includes a first synchronous wheel located on the outer wall of the limiting sleeve, and a second synchronous wheel connected to the outer wall of the first synchronous wheel via a synchronous belt. The second synchronous wheel is fixedly connected to the outer wall of the rotating shaft.

[0008] As a further improvement of this utility model, the elastic component includes a spring located on the inner wall of the rotating shaft, a slide plate slidably connected to the inner wall of the rotating shaft, one end of the spring being connected to the slide plate, and the other end of the spring being connected to the inner wall of the rotating shaft.

[0030] Example 1:

[0031] like Figures 1-4As shown, an adjustable multi-functional cutting tool for slitting and packaging includes a support frame 1. A limiting roller 3 is rotatably connected to the inner wall of the support frame 1. A limiting sleeve 4 is slidably connected to the outer wall of the limiting roller 3. A tool holder 9 is rotatably connected to the outer wall of the limiting sleeve 4. A rotating shaft 8 is connected to the outer wall of the limiting sleeve 4 through a linkage component. The rotating shaft 8 is rotatably connected to the inner wall of the tool holder 9. A tenon 10 is fixedly connected to the outer wall of the rotating shaft 8. An elastic component is provided on the inner wall of the rotating shaft 8. A bolt 14 is threadedly connected to the inner wall of the rotating shaft 8. A blade 13 is slidably connected to the outer wall of the rotating shaft 8. A slider 15 is fixedly connected to the rear end of the tool holder 9. A bidirectional lead screw 16 is connected to the inner wall of the slider 15 through a threaded sleeve. The bidirectional lead screw 16 is rotatably connected to the inner wall of the support frame 1. A knob 17 is fixedly connected to the right end of the bidirectional lead screw 16. The right end of the support frame 1 is connected to the knob 17 through a limiting component.

[0032] Specifically, the motor 2 drives the limit roller 3 to rotate. The limit roller 3 is slidably connected to the limit sleeve 4 on its outer wall. Under the action of the shape of the limit roller 3, the limit sleeve 4 will rotate synchronously. When it is necessary to replace the blade 13, first turn off the motor 2 to stop the blade 13 from rotating. Then rotate the bolt 14, which is threaded to the inner wall of the rotating shaft 8. Remove the bolt 14 from the rotating shaft 8. At this time, the bolt 14 will no longer limit the blade 13, so the blade 13 can be removed from the rotating shaft 8 for replacement. When replacing the new blade 13, put the new blade 13 on the rotating shaft 8 and use the tenon 10 to limit the blade 13 to prevent it from rotating circumferentially. Then screw the bolt 14 into the rotating shaft 8. During the process of the bolt 14 moving into the rotating shaft 8, the bolt 14 will push the slide 12. The slide 12 slides on the inner wall of the rotating shaft 8 and compresses the spring 11 at the same time. The spring 11 plays a buffering and adjusting role to ensure that the locking force of the bolt 14 is uniform and that the blade 13 is installed firmly.

[0033] The linkage component includes a timing wheel 5 located on the outer wall of the limiting sleeve 4. The outer wall of the timing wheel 5 is connected to a timing wheel 7 via a timing belt 6. The timing wheel 7 is fixedly connected to the outer wall of the rotating shaft 8. The elastic component includes a spring 11 located on the inner wall of the rotating shaft 8. A sliding plate 12 is slidably connected to the inner wall of the rotating shaft 8. One end of the spring 11 is connected to the sliding plate 12, and the other end of the spring 11 is connected to the inner wall of the rotating shaft 8. A motor 2 is mounted on the right end of the support frame 1 via a fixing frame. The drive end of the motor 2 is fixedly connected to the right end of the limiting roller 3. The diameter of the bolt 14 is larger than the diameter of the rotating shaft 8.

[0034] Specifically, the motor 2 is started, and the drive end of the motor 2 is connected to the right end of the limiting roller 3. The outer wall of the limiting sleeve 4 is equipped with a synchronous wheel 5. The synchronous wheel 5 is connected to the synchronous wheel 7 fixed on the outer wall of the rotating shaft 8 through the synchronous belt 6. When the limiting sleeve 4 rotates, it will drive the rotating shaft 8 to rotate through the synchronous wheel 5, the synchronous belt 6 and the synchronous wheel 7. The blade 13 is slidably connected to the outer wall of the rotating shaft 8, and a tenon 10 is fixed on the outer wall of the rotating shaft 8. The tenon 10 can prevent the blade 13 from rotating arbitrarily in the circumferential direction during the rotation, ensuring that the blade 13 rotates stably with the rotating shaft 8, thereby performing the cutting operation on the packaging material.

[0035] Example 2:

[0036] As one of the optimized structural designs for Example 1, such as Figures 1-4 As shown, the limiting assembly includes a fixed plate 18 located at the right end of the support frame 1. A slide rod 19 is fixedly connected to the top of the fixed plate 18. A ratchet plate 20 is slidably connected to the outer wall of the slide rod 19. The ratchet plate 20 is located at the top of the knob 17. A second spring 21 is provided on the outer wall of the slide rod 19. One end of the second spring 21 is connected to the top of the fixed plate 18, and the other end of the second spring 21 is connected to the bottom of the lifting knob 22. The lifting knob 22 is fixedly connected to the top of the ratchet plate 20.

[0037] Specifically, when it is necessary to adjust the position between the two blades 13, the operator holds the lifting knob 22 and lifts it upwards. The lifting knob 22 is fixed to the top of the ratchet plate 20, which is slidably connected to the slide bar 19. The slide bar 19 is fixed to the top of the fixed plate 18. A second spring 21 is sleeved on the outer wall of the slide bar 19. One end of the second spring 21 is connected to the top of the fixed plate 18, and the other end is connected to the bottom of the lifting knob 22. When the lifting knob 22 is lifted upwards, the second spring 21 will be stretched, causing the ratchet plate 20 to move upwards and removing the limit on the knob 17. At this time, the knob 17 is rotated. The knob 17 is fixed to the right end of the double-acting screw 16. Rotating the knob 17 will drive the double-acting screw 16 to rotate. The rear end of the tool holder 9 is fixedly connected to the slider 15. The inner wall of the slider 15 is connected to the double-acting screw 16 through a threaded sleeve. When the double-acting screw 16 rotates, the slider 15 will drive the tool holder 9 to move under the action of the threaded sleeve. Since the blade 13 is installed on the tool holder 9, the position of the two blades 13 can be adjusted. Conversely, after the force applied to the lifting button 22 is removed, the ratchet plate 20 will move downward under the action of the second spring 21, so that the ratchet plate 20 limits the knob 17.

[0038] Working principle: After the cutter is fixed in the appropriate position by the support frame 1, the motor 2 is started and drives the limiting sleeve 4 to rotate through the limiting roller 3. Simultaneously, the limiting sleeve 4 rotates, and under the action of the first synchronous pulley 5, the synchronous belt 6, and the second synchronous pulley 7, it drives the blade 13 to cut through the rotating shaft 8. When it is necessary to adjust the position between the two blades 13, simply hold the lifting knob 22 to lift the ratchet plate 20 upwards, stretching the second spring 21, causing the ratchet plate 20 to release its limitation on the knob 17. Then, rotating the knob 17 drives the bidirectional lead screw 16 to rotate, and under the action of the threaded sleeve, it drives the tool holder 9 through the slider 15. Move and adjust the positions of the two blades 13. When it is necessary to replace the blade 13, turn off the motor 2 to stop the blade 13 from rotating. Then, rotate the bolt 14 to remove the bolt 14 from the rotating shaft 8, so that the bolt 14 can no longer limit the blade 13. The blade 13 can then be removed from the rotating shaft 8 for replacement. Conversely, after the new blade 13 is put on the rotating shaft 8 and the tenon 10 limits the blade 13, the bolt 14 is removed and rotated onto the rotating shaft 8. When the bolt 14 moves into the rotating shaft 8, it will push the slide 12, which will compress the spring 11 to ensure that the bolt 14 has a uniform locking force.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
