Description

Technical Field

[0001] This utility model relates to the field of paper product processing equipment technology, and in particular to a tube cutting machine for paper product processing. Background Technology

[0002] Paper products come in a variety of forms, including cardboard, paper, and paper tubes. Paper tubes are tubular components made from paper as raw material. Due to their versatility, environmental friendliness, and cost-effectiveness, paper tubes have become a key material in industries such as manufacturing, packaging, construction, and culture. In the production process of paper tubes, long paper tubes are usually cut into short tubes of different lengths or angles according to actual needs.

[0003] Paper tube cutting typically utilizes tube cutting machines. A search revealed Chinese patent CN220638093U, titled "A Tube Cutting Machine for Paper Product Processing," which describes a system comprising: a base plate, an intelligent control box mounted on the upper surface of the base plate, a vacuum cleaner mounted on the upper surface of the base plate, support legs on the sides of the base plate, a base at the top of the support legs, and a supporting cross plate on the inner side of the base.

[0004] A first motor is mounted on the outer side. A chuck mechanism is installed on the inner side of the supporting cross plate. A slide bar is installed on the inner side of the supporting cross plate. A first slider is mounted on the outer surface of the slide bar. The side of the first slider is attached to a connecting plate. A fixing plate is installed on the inner wall of the base. A first through hole is opened inside the fixing plate. A first electric telescopic rod is mounted on the fixing plate through the first through hole. A first clamping plate is installed at the output end of the first electric telescopic rod. A second through hole is opened on the bottom surface of the base. A second electric telescopic rod is installed inside the second through hole. A second clamping plate is installed at the output end of the second electric telescopic rod. A mounting hole is opened on the bottom surface of the base. A collection chamber is installed inside the mounting hole. A fixing block is installed on the bottom surface of the base. The upper surface of the base...

A second motor is mounted on the top surface of the support frame, and a flat plate is provided on the outer side of the base, with an operating table mounted on the upper surface of the plate. This design addresses the problem that "this tube cutting machine for paper product processing can only cut a single type of paper tube and cannot cut different lengths." However, during use, the cutting blades require maintenance based on the actual cutting situation. Since the cutting blades are generally mounted on the output shaft of the cutting motor via flanges, they need to be removed one by one using tools, resulting in a long maintenance time for the cutting blades and extending the overall maintenance time.

[0005] Therefore, how to provide a tube cutting machine for paper product processing is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a tube cutting machine for paper product processing. This invention solves the problem that the cutting discs of existing tube cutting machines are installed via flanges, requiring tools to remove them one by one, which leads to a long maintenance time for the cutting discs and thus extends the overall maintenance time.

[0007] A tube cutting machine for paper product processing according to an embodiment of the present invention includes a tube cutting frame, a movable frame, a cutting motor, and a cutting disc. The tube cutting frame is stably placed on the ground by a support rod. The movable frame is movably connected to one side of the tube cutting frame, and the cutting motor is fixedly connected to the side of the movable frame.

The mounting base is fixedly connected to the output shaft end of the cutting motor. The snap-fit ​​kit is provided on the side of the mounting base. The cutting disc is movably fitted onto the side of the mounting base. A slot is provided on the inner wall of the cutting disc corresponding to the position of the snap-fit ​​kit, and part of the snap-fit ​​kit is snapped into the slot.

[0008] The snap-fit ​​kit includes at least two sets of snap-fit ​​components, which are symmetrically arranged on the side of the mounting base.

[0009] The snap-fit ​​assembly includes a movable groove, a guide block, a snap-fit ​​head, and a first spring member. The movable groove is formed on the side of the mounting base. The guide block is movably connected inside the movable groove. The snap-fit ​​head is fixedly connected to the side of the guide block. The other end of the snap-fit ​​head extends to the outside of the movable groove and snaps into the inside of the groove. The first spring member is movably sleeved on the surface of the snap-fit ​​head located inside the movable groove. One end of the first spring member is movably connected to the surface of the guide block. The other end of the first spring member is movably connected to the inner wall of the movable groove near the snap-fit ​​groove. The end of the snap-fit ​​head located inside the snap-fit ​​groove has a chamfer.

[0010] The snap-fit ​​kit also includes a limiting groove, a driving column, a driving sleeve block, a driving rod, and a second spring. The limiting groove is located on the side of the mounting base away from the output shaft of the cutting motor and communicates with the movable groove. The driving column is fixedly connected inside the limiting groove. The driving sleeve block is movably fitted onto the surface of the driving column and is movably connected inside the limiting groove. One end of the driving rod is rotatably connected to the side of the driving sleeve block, and the other end of the driving rod is rotatably connected to the side of the guide block away from the snap-fit ​​head. The second spring is movably fitted onto the surface of the driving column located inside the driving sleeve block. One end of the second spring is movably connected to the protruding position of the driving column, and the other end of the second spring is movably connected to the inner wall of the driving sleeve block near the cutting motor.

[0011] The mounting base is a hexagonal prism base, and the shape of the inner wall of the cutting disc matches the shape of the mounting base.

[0012] The side of the drive sleeve is provided with a hand pull groove.

[0013] The beneficial effects of this utility model are:

[0014] By setting up an installation component, the cutting disc is fixed by a snap-fit ​​after being fitted onto the installation component. When rotating, the clamp and guide block on the installation component move towards the slot through centrifugal force, which increases the stability of the cutting disc snap-fit. When removing it, the cutting disc can be easily removed by simply moving the installation component. This solves the problem of existing pipe cutting machines where the cutting discs are installed through flanges, requiring tools to remove them one by one, which leads to a long maintenance time for the cutting discs and extends the overall maintenance time.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] refer to Figure 1-4In this embodiment, the device includes a pipe cutting frame 1, a movable frame 2, a cutting motor 3, and a cutting disc 4. The pipe cutting frame 1 is stably placed on the ground by a support rod. The movable frame 2 is movably connected to one side of the pipe cutting frame 1. The cutting motor 3 is fixedly connected to the side of the movable frame 2. The output shaft of the cutting motor 3 passes through the movable frame 2 and extends to the other side of the movable frame 2. A mounting assembly 5 is provided on the end face of the cutting motor 3 extending to the other side of the movable frame 2. The mounting assembly 5 includes a mounting base 6 and a snap-fit ​​kit 7. The mounting base 6 is a hexagonal prism base, so the mounting base 6 has six sides. The shape of the inner wall of the cutting disc 4 is similar to the shape of the mounting base 6. The design improves the fit and prevents the mounting base 6 and the cutting disc 4 from shaking. The mounting base 6 is fixedly connected to the output shaft end of the cutting motor 3. The snap-fit ​​kit 7 is set on the side of the mounting base 6. The cutting disc 4 is movably fitted onto the side of the mounting base 6. The inner wall of the cutting disc 4 has a slot 8 corresponding to the position of the snap-fit ​​kit 7. Part of the snap-fit ​​kit 7 is snapped into the inside of the slot 8. The snap-fit ​​kit 7 includes at least two sets of snap-fit ​​components 9. At least two sets of snap-fit ​​components 9 are symmetrically arranged on the side of the mounting base 6. In this embodiment, the number of snap-fit ​​components 9 is the same as the number of the side of the mounting base 6.

[0023] The latching assembly 9 includes a movable groove 10, a guide block 11, a latch head 12, and a first spring member 13. The movable groove 10 is formed on the side of the mounting base 6. The guide block 11 is movably connected to the inside of the movable groove 10. The latch head 12 is fixedly connected to the side of the guide block 11, and the other end of the latch head 12 extends to the outside of the movable groove 10 and latches into the inside of the latch groove 8. The first spring member 13 is movably sleeved on the surface of the latch head 12 located inside the movable groove 10. One end of the first spring member 13 is movably connected to the surface of the guide block 11, and the other end of the first spring member 13 is movably connected to the inner wall of the movable groove 10 near the latch groove 8. The end of the latch head 12 located inside the latch groove 8 has a chamfer. The purpose of the chamfer is to ensure that when the cutting disc 4 is fitted onto the surface of the mounting base 6... The chuck 12 can be easily squeezed, causing it to retract into the movable groove 10 through a chamfer. It should be noted that the movable groove 10 is a square groove, the guide block 11 is a square block, and the inner wall of the movable groove 10 and the side of the guide block 11 are both smooth, thus reducing the sliding resistance of the guide block 11. The first spring 13 limits the length of the chuck 12 extending out of the movable groove 10. During operation, the cutting disc 4 is first aligned with the mounting base 6 and fitted onto the side of the mounting base 6. Then, the cutting disc 4 is pushed towards the mounting base 6. The movement of the cutting disc 4 will squeeze the chuck 12, causing it to retract into the movable groove 10. When the cutting disc 4 moves the slot 8 to the position of the chuck 12, the chuck 12 will be inserted into the slot 8.

[0024] refer to Figure 1-4In this embodiment, the snap-fit ​​kit 7 further includes a limiting groove 14, a driving column 15, a driving sleeve block 16, a driving rod 17, and a second spring 18. The limiting groove 14 is located on the side of the mounting base 6 away from the output shaft of the cutting motor 3, and communicates with the movable groove 10. The driving column 15 is fixedly connected inside the limiting groove 14. The driving sleeve block 16 is movably sleeved on the surface of the driving column 15. A hand-pull groove 19 is provided on the side of the driving sleeve block 16, and the driving sleeve block 16 is movably connected inside the limiting groove 14. One end of the driving rod 17 is rotatably connected to the side of the driving sleeve block 16, and the other end of the driving rod 17 is rotatably connected to the side of the guide block 11 away from the snap head 12. The second spring 18 is movably sleeved on the surface of the driving column 15 located inside the driving sleeve block 16. One end of the second spring 18 is movably connected to the protruding position of the driving column 15, and the other end of the second spring 18 is movably connected to the inner wall of the driving sleeve block 16 near the cutting motor 3. Figure 4 As shown, the second spring 18 and the first spring 13 are in a balanced state, so the positions of the movable sleeve, guide block 11, and clamp 12 are also in a balanced state. The guide block 11 is positioned by the driving rod 17. When the cutting motor 3 starts to rotate, the rotation of the cutting motor 3 drives the mounting base 6 to rotate. The rotation of the mounting base 6 will drive the movable groove 10 and the guide block 11, clamp 12, and first spring 13 in the movable groove 10 to rotate. In this way, the guide block 11 and clamp 12 generate centrifugal force. At this time, the guide block 11 will move towards the clamping groove 8 in the movable groove 10. The clamp 12 will extend out of the movable groove 10 and be inserted into the depth of the clamping groove 8 by the centrifugal force. In this way, the fixing strength of the cutting disc 4 will be improved under the high-speed rotation of the mounting assembly 5 and the cutting disc 4. It should be noted that when the driving rod 17 is perpendicular to the guide sleeve... After the cutting disc 4 is in the high-speed rotation state, the guide block 11, the chuck 12, the drive sleeve block 16, the first spring 13 and the second spring 18 are in a balanced state under the high-speed rotation of the cutting disc 4. When removing it, the cutting motor 3 needs to be stopped. After the cutting disc 4 is stable, squeeze the hand pull groove 19 on the drive sleeve block 16 and move the drive sleeve block 16 away from the cutting motor 3. The movement of the drive sleeve block 16 drives the drive rod 17 to pull the guide block 11 to move in the movable groove 10. The guide block 11 will pull the chuck 12 to retract into the movable groove 10 in the direction of the drive column 15. At this time, the chuck 12 will separate from the chuck groove 8. Then, move the cutting disc 4 away from the cutting motor 3 to easily remove the cutting disc 4. This achieves the effect of convenient fixing and removing the cutting disc 4 and greatly improves the maintenance efficiency of the cutting disc 4.
