Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard box production equipment, and in particular to a paper slitting machine for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard boxes, as an important carrier in the packaging and transportation industry, require multiple processes in their production. Among these, the paper slitting process is crucial in determining the quality and dimensional accuracy of the box forming. The paper slitting machine, specifically designed to cut large-format corrugated cardboard into several narrow strips according to preset dimensions, plays a vital role in the production line. Efficient and precise paper slitting not only ensures the assembly accuracy of the boxes but also reduces the processing pressure on subsequent steps, improving overall production efficiency. With the increasing market demand for diversified box specifications and flexible production, the structural optimization and ease of operation of the paper slitting machine have become particularly important.

[0003] Existing corrugated cardboard box slitting machines typically consist of a frame, transmission device, disc cutter assembly, guide rollers, and control system. The transmission device drives multiple disc cutters to rotate synchronously via a timing belt or gears, achieving longitudinal cutting of the cardboard. The disc cutter assembly is mounted on a beam or cutter shaft and fixed in position by mechanical fasteners, thus enabling cutting according to different production specifications. The guide rollers stabilize the cardboard's trajectory, ensuring accurate positioning when the cardboard enters the cutting area, and, in conjunction with the control system, achieve continuous, high-speed slitting operations. This structure, while ensuring basic slitting functions, also possesses a certain degree of durability and processing stability.

[0004] However, existing structures generally use bolts to fix the position of the disc cutter. This method requires repeatedly tightening and loosening the bolts when adjusting the cutter position, which is not only cumbersome and time-consuming, but also prone to positioning deviations during repeated tightening and loosening, resulting in insufficient cutter spacing accuracy and affecting the dimensional consistency of cardboard slitting. For production scenarios that require frequent changes in specifications, this problem will significantly reduce production efficiency and increase the labor intensity and error rate of operators, urgently requiring structural improvements to enhance the efficiency and accuracy of cutter position adjustment. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a paper slitting machine for corrugated cardboard box production, which aims to improve the existing structure of the disc cutter, which is fixed by bolts, resulting in repeated tightening and loosening of bolts when adjusting the cutter position, which is time-consuming and has insufficient positioning accuracy.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a paper slitting machine for corrugated cardboard box production, comprising a support frame, a column fixedly connected to the upper surface of the support frame, a cutter shaft fixedly connected to the inner wall of the column, a fixing ring slidably connected to the outer wall of the cutter shaft, and a quick-release assembly provided inside the fixing ring;

[0007] The quick-release assembly includes a threaded rod II, which is disposed inside a fixed ring. A quick-release post is fixedly connected to the inner wall of the fixed ring, and a disc cutter is fixedly connected to the outer wall of the fixed ring. The inner wall of a quick-release block is slidably connected to the outer wall of the quick-release post, and the outer wall of the quick-release block is fixedly connected to the inner wall of the cutter shaft. A fixing groove is formed inside the quick-release block. The inner wall of the quick-release post is threadedly connected to the outer wall of the threaded rod II. A conical block is rotatably connected to one end of the threaded rod II. A slider II is slidably connected to the outer wall of the conical block. A fixing ball is fixedly connected to the outer wall of the slider II. A spring II is fixedly connected to the outer wall of the slider II. The other end of the spring II is fixedly connected to the inner wall of the quick-release post, and the outer wall of the fixing ball is slidably connected to the fixing groove inside the quick-release block.

[0008] Furthermore, a slider is slidably connected to the inner wall of the column, a spring is fixedly connected to the outer wall of the slider, a limit post is fixedly connected to one end of the spring, a threaded rod is rotatably connected to the upper surface of the limit post, the threaded rod is threadedly connected to the inner wall of the column, and a pressure roller is rotatably connected to the inner wall of the slider.

[0009] Furthermore, a workbench is fixedly connected to the upper surface of the bracket, a limit plate is fixedly connected to the upper surface of the workbench, and a protective block is fixedly connected to the inner wall of the column.

[0010] Furthermore, the workbench is fitted to the column, a control box is fixedly connected to the outer wall of the support, and a crossbeam is fixedly connected to the inner wall of the support.

[0011] Furthermore, a motor is fixedly connected to the inner wall of the control box, a gear is fixedly connected to the output end of the motor, and a cutter shaft is fixedly connected to the outer wall of the gear.

[0012] Furthermore, a second gear is provided on one side of the outer wall of the column, and the first gear meshes with the second gear. Another cutter shaft is fixedly connected to the outer wall of the second gear.

[0013] Furthermore, a control panel is fixedly connected to the inner wall of the control box, and rollers are rotatably connected to the inner wall of the column.

[0014] Furthermore, a pressure roller is rotatably connected to the inner wall of the column, and the outer wall of the conical block is slidably connected to the inner wall of the quick-release column.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, by setting a fixing ring on the outer wall of the cutter shaft and an internal quick-release assembly, and utilizing the cooperation of the threaded rod, the conical block, the slider and the fixing ball, the disc cutter can be quickly disassembled and its position adjusted. The cutter can be replaced and its specifications adjusted without repeatedly tightening and loosening the bolts, which greatly shortens the adjustment time. At the same time, the structure can reliably position the disc cutter in the locked state, reducing loosening or displacement during use and ensuring cutting accuracy and stability.

[0017] In this invention, an elastic pressing structure consisting of a slider, a spring, a limiting post, and a pressure roller is set inside the column. This allows the pressure roller to maintain a stable pressing force while making slight fluctuations during the cutting process. This adapts to changes in the thickness and surface unevenness of the cardboard, ensuring that the cardboard runs smoothly on the worktable and preventing warping, shaking, or deviation. This improves the straightness and edge quality of the cut and enhances the overall slitting effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 5 The present invention provides an embodiment of a paper slitting machine for corrugated cardboard box production, including a support 1. The support 1 provides support and installation foundation for the entire paper slitting machine and is used to support components such as the workbench 4 to ensure the stability of the whole machine structure. A column 6 is fixedly connected to the upper surface of the support 1. A knife shaft 13 is fixedly connected to the inner wall of the column 6. A fixing ring 15 is slidably connected to the outer wall of the knife shaft 13. A quick-release component is provided inside the fixing ring 15.

[0027] The quick-release assembly includes a threaded rod 22, which drives the tapered block 24 to move axially via rotation, thereby controlling the locking or releasing state of the fixed ball 26 and realizing the quick release and adjustment of the disc cutter 14. The threaded rod 22 is located inside the fixed ring 15. A quick-release post 17 is fixedly connected to the inner wall of the fixed ring 15, and the disc cutter 14 is fixedly connected to the outer wall of the fixed ring 15. The inner wall of the quick-release block 23 is slidably connected to the outer wall of the quick-release post 17. The quick-release block 23 is used to accommodate the fixed ball 26 in the fixed state to lock the disc cutter 14. The outer wall of the quick-release block 23 is fixedly connected to the inner wall of the cutter shaft 13. A fixing groove 28 is opened inside the quick-release block 23, and the inner wall of the quick-release post 17 is threaded. On the outer wall of the threaded rod 22, the threaded rod 22 drives the conical block 24 to move axially by rotation, thereby controlling the locking or releasing state of the fixed ball 26, realizing the quick release and adjustment of the disc cutter 14. One end of the threaded rod 22 is rotatably connected to the conical block 24, the outer wall of the conical block 24 is slidably connected to the slider 25, the outer wall of the slider 25 is fixedly connected to the fixed ball 26, and the outer wall of the slider 25 is fixedly connected to the spring 27. The spring 27 provides a restoring force for the slider 25 and the fixed ball 26 to ensure the stability of the locking state. The other end of the spring 27 is fixedly connected to the inner wall of the quick release post 17, and the outer wall of the fixed ball 26 is slidably connected to the fixing groove inside the quick release block 23.

[0028] Specifically, when using this corrugated cardboard box production paper slitting machine, the cardboard is placed on the worktable 4. With the coordinated action of the roller 21, the cutter shaft 13, and the disc cutter 14, the cardboard is precisely cut. The quick-release structure, through the cooperation of the fixing ring 15, the threaded rod 22, the conical block 24, the slider 25, and the fixing ball 26, enables the quick disassembly and position adjustment of the disc cutter 14. When the operator rotates the threaded rod 22, the conical block 24 moves along the quick-release column 17, causing the slider 25 and the fixing ball 26 to move radially, allowing the disc cutter 14 to slide freely on the cutter shaft 13 or be removed. After adjustment, the threaded rod 22 rotates in the opposite direction, the conical block 24 returns to its original position, and the spring 27 pushes the slider 25 and the fixing ball 26 to relock the disc cutter 14, achieving stable fixation. This structure eliminates the need for repeated tightening and loosening of bolts to complete cutter replacement and size adjustment, significantly shortening operation time while improving cutter positioning accuracy and reliability, ensuring paper slitting efficiency and cutting quality.

[0029] Reference Figure 1 - Figure 5 A slider 20 is slidably connected to the inner wall of the column 6.

The spring 19 is fixedly connected to the outer wall of the slider 20. One end of the spring 19 is fixedly connected to the limit post 18. The upper surface of the limit post 18 is rotatably connected to the threaded rod 8. The threaded rod 8 is used to drive the slider 20 to move up and down precisely, thereby adjusting the gap between the pressure roller 16 and the worktable 4. The threaded rod 8 is threadedly connected to the inner wall of the column 6. The pressure roller 16 is rotatably connected to the inner wall of the slider 20. The worktable 4 is fixedly connected to the upper surface of the bracket 1. The limit plate 5 is fixedly connected to the upper surface of the worktable 4.

The outer wall of the support 1 is fixedly connected to the control box 3. The inner wall of the support 1 is fixedly connected to the crossbeam 2. The inner wall of the control box 3 is fixedly connected to the motor 10. The motor 10 provides rotational power to the cutter shaft 13 and drives the disc cutter 14 to cut through gear transmission. The output end of the motor 10 is fixedly connected to the gear 11. The outer wall of the gear 11 is fixedly connected to the cutter shaft 13. The outer wall of the column 6 is provided with the gear 22. The gear 11 and the gear 22 mesh with each other. The outer wall of the gear 22 is fixedly connected to another cutter shaft 13. The inner wall of the control box 3 is fixedly connected to the control panel 9. The control box 3 realizes the start and stop control of the equipment, parameter adjustment and operation status display. The inner wall of the column 6 is rotatably connected to the roller 21 and the inner wall of the column 6 is rotatably connected to the pressure roller 16. The outer wall of the conical block 24 is slidably connected to the inner wall of the quick-release column 17.

[0030] Specifically, during the paperboard conveying and cutting process, the slider 20, together with the spring 19 and the pressure roller 16, forms an elastic clamping system. This system can generate slight up-and-down movement when the paperboard is subjected to a reaction force, thereby adapting to changes in paperboard thickness and surface unevenness. The limiting post 18 and the threaded rod 8 can achieve precise adjustment of the slider 20, thereby controlling the gap between the pressure roller 16 and the worktable 4. This ensures that the paperboard receives uniform pressure when passing through the pressure roller 16. The continuous action of the spring 19 causes the pressure roller 16 to apply a stable clamping force to the paperboard, ensuring that the paperboard is tightly attached to the surface of the worktable 4, preventing it from warping, shaking, or shifting. This improves the accuracy and stability of the cutting process. This elastic clamping structure not only improves the stability of the paperboard during the paper separation process but also effectively improves the straightness and edge quality of the cut of the disc cutter 14, achieving high-precision and high-efficiency paper separation processing.

[0031] Working principle: When a corrugated cardboard box production paper slitting machine is needed, firstly, the cardboard is placed on the upper surface of the worktable 4. Through the coordinated action of rollers 21, cutter shaft 13, and disc cutter 14, the cardboard is cut. When it is necessary to adjust the cutting size or change the cutter, the operator first rotates the threaded rod 22 connected internally to the fixed ring 15. The rotation of the threaded rod 22 causes the conical block 24, which is rotatably connected at one end, to move axially along the inner wall of the quick-release column 17. During the movement, the conical block 24 pushes the slider 25, which is slidably connected to its outer wall, to move radially. The slider 25 then causes the fixed ball 26, which is fixedly connected to its outer wall, to move outward. When the fixed ball 26 slides into the fixed groove 28 inside the quick-release block 23, the fixed ring 15 and the disc cutter 14 fixedly connected to its outer wall can slide freely on the cutter shaft 13 or be removed, thereby realizing quick disassembly and position adjustment. After the cutter adjustment or replacement is completed, the threaded rod 22 is rotated in the opposite direction, the conical block 24 is reset, and under the elastic action of the spring 27, the slider 25 and the fixed ball 26 re-enter the fixed groove 28, realizing the reliable locking of the disc cutter 14 in the new position. This quick-release structure can complete the replacement and position adjustment of the disc cutter 14 without repeatedly tightening and loosening the bolts, which greatly shortens the adjustment time and improves the accuracy and reliability of the cutter positioning.

[0032] Furthermore, during the paperboard conveying and cutting process, the slider 20, which is slidably connected to the inner wall of the column 6, serves to support and guide the pressure roller 16. One end of the spring 19, which is fixedly connected to the outer wall of the slider 20, is fixedly connected to the limiting post 18. When the pressure roller 16 is subjected to the reaction force of the paperboard, the spring 19 will undergo elastic deformation, thereby allowing the pressure roller 16 to float slightly up and down while maintaining the clamping force, so as to adapt to changes in the thickness and surface unevenness of the paperboard. The threaded rod 8, which is rotatably connected to the upper surface of the limiting post 18, can achieve precise adjustment of the position of the slider 20 through the threaded engagement with the inner wall of the column 6, thereby controlling the gap between the pressure roller 16 and the worktable 4. When the paperboard passes through the pressure roller 16, the pressure roller 16 applies uniform pressure downward under the continuous action of the spring 19, so that the paperboard is stably attached to the surface of the worktable 4, avoiding inaccurate cutting position due to warping, shaking or displacement. This elastic clamping structure can not only effectively improve the stability of the paperboard during the cutting process, but also improve the straightness and edge quality of the cut of the disc cutter 14.

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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
