A high efficiency paper tube cutting blade

Abstract

This utility model discloses a high-efficiency paper tube cutting blade, which includes a connecting base. A connecting seat, which is C-shaped, is fixedly connected to the side surface of the connecting base. A rotating shaft is rotatably connected to the two inner surfaces of the connecting seat, and a rotating component is rotatably connected to the side surface of the rotating shaft. The bottom end of the rotating component is an inclined surface. Initial fixation is released by first removing the fixing bolts in the fixing hole and the first threaded hole. Then, rotating the rotating component clockwise causes the threaded column to move the extrusion block away from the through hole, and its inclined surface separates from the inclined surface of the second threaded hole. At this time, the rotating component near the bottom end of the connecting seat loses external force and rotates vertically at a certain angle under the action of gravity. Simultaneously, the rotating shaft rotates synchronously inside the connecting seat, and the protrusion of the rotating component disengages from the recess of the connecting block, completing the disassembly. The combination of these two fixing methods ensures stable blade operation.

Description

Technical Field

[0001] This utility model relates to the field of cutting blade technology, specifically a high-efficiency paper tube cutting blade. Background Technology

[0002] Paper tubes, as the name suggests, are cylindrical containers made from paper using specific processes. They are typically composed of multiple layers of tightly bonded paper, possessing high strength and stability, and are widely used in packaging, storage, and transportation. The outer surface of a paper tube is smooth and flat, while the inner wall is designed with different structures to adapt to the loading requirements of various items.

[0003] During long-term cutting operations, the continuous rotation of the paper tube subjectes the blade to a combination of forces, including reaction forces and cutting vibrations. In this situation, the traditional single-screw fixing method has significant drawbacks. For example, the screw cannot withstand continuous and complex forces and is prone to loosening, leading to blade misalignment. Furthermore, single-bolt fixing typically only has one or a few fixing points, leaving the blade insufficiently secured. After prolonged use, the blade is prone to wobbling or swinging during cutting, severely affecting cutting stability. Utility Model Content

[0004] This invention provides a high-efficiency paper tube cutting blade that enables the screw, rotating parts and extrusion block to cooperate with each other to achieve a double fixing effect on the blade, thereby enhancing the stability of the blade to a certain extent.

[0005] To achieve the above objectives, a high-efficiency paper tube cutting blade is provided, comprising a connecting base, a connecting seat fixedly connected to the side surface of the connecting base, the connecting seat being C-shaped, a rotating shaft rotatably connected to the inner two sides of the connecting seat, a rotating component rotatably connected to the side surface of the rotating shaft, the bottom end of the rotating component being inclined, a sliding block laterally slidably connected to the inner two sides of the connecting seat near the rotating shaft, a pressing block fixedly connected to the side surface of the sliding block, a second threaded hole being opened on the side surface of the connecting base, a through hole being opened on the side surface of the connecting seat near the second threaded hole, a threaded post being provided in the second threaded hole, the threaded post engaging with the second threaded hole, one end of the side surface of the threaded post passing through the through hole and rotatably connected to the side surface of the pressing block, the pressing block being trapezoidal, a rotating component fixedly connected to one end of the side surface of the threaded post away from the pressing block, a connecting block being provided near the recess of the rotating component, and a blade body fixedly connected to the side surface of the connecting block.

[0006] According to the aforementioned high-efficiency paper tube cutting blade, a label sticker is adhesively attached to the side surface of the blade body away from the connecting seat. Multiple fixing holes are formed on the side surface of the blade body away from the center. Heat dissipation holes are formed on the side surface of the blade body away from the label sticker. Multiple threaded holes of the first type are formed on the side surface of the connecting seat away from the connecting base, and these threaded holes correspond in position to the fixing holes. The label sticker is provided for detailed blade identification; the fixing holes are for easy bolt penetration; the heat dissipation holes are for ventilation and heat dissipation; and the threaded holes are for easy bolt installation.

[0007] According to the aforementioned high-efficiency paper tube cutting blade, the connecting base is T-shaped, and a mounting hole is provided on the upper surface of the connecting base near the bottom end. The mounting hole is provided to accommodate external connectors and allow the device to be installed in the desired position.

[0008] According to the aforementioned high-efficiency paper tube cutting blade, a mounting groove is formed on the lower surface of the connecting base, and an anti-slip pad is fixedly connected in the mounting groove. The anti-slip pad is provided to enhance friction with the worktable surface.

[0009] According to the aforementioned high-efficiency paper tube cutting blade, the number of mounting holes is multiple, the label sticker is circular, and the blade body is made of high-speed steel.

[0010] According to the aforementioned high-efficiency paper tube cutting blade, the outer arc surface of the rotating component is provided with recessed texture, and the area of ​​the outer arc surface of the rotating component near the recessed texture is made of natural rubber.

[0011] According to the aforementioned high-efficiency paper tube cutting blade, the anti-slip pad is made of natural rubber, and the connecting block is convex in shape.

[0012] According to the aforementioned high-efficiency paper tube cutting blade, the side surface of the blade body near the connecting seat is made of a magnetic material, while the contact surface of the connecting seat near the blade body is made of iron. The magnetic material of the connecting seat is used to improve ease of fixing during the process.

[0013] The beneficial effects of this utility model are as follows: First, the fixing bolts in the fixing hole and the first threaded hole are removed to release the initial fixing state. Then, the rotating component is rotated clockwise, causing the threaded column to gradually move the extrusion block away from the through hole, thus separating its inclined surface from the inclined surface of the second threaded hole. At this time, the external force on the rotating component near the bottom of the connecting seat disappears, and under the action of gravity, the rotating component rotates a certain angle in the vertical direction. Simultaneously, the rotating shaft rotates synchronously inside the connecting seat, allowing the protrusion of the rotating component to smoothly disengage from the recess of the connecting block, thereby completing the disassembly process. The two fixing methods work together to facilitate stable operation of the blade.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figures 1 to 4 This utility model discloses a high-efficiency paper tube cutting blade, comprising a connecting base 1, a connecting seat 4 fixedly connected to the side surface of the connecting base 1, the connecting seat 4 being C-shaped, a rotating shaft 13 rotatably connected to the inner two sides of the connecting seat 4, a rotating component 6 rotatably connected to the side surface of the rotating shaft 13, the bottom end of the rotating component 6 being an inclined surface, a sliding block 10 laterally slidably connected to the inner two sides of the connecting seat 4 near the rotating shaft 13, a pressing block 12 fixedly connected to the side surface of the sliding block 10, a second threaded hole 16 formed on the side surface of the connecting base 1, a through hole 17 formed on the side surface of the connecting seat 4 near the second threaded hole 16, a threaded post 15 disposed in the second threaded hole 16, the threaded post 15 and the second threaded hole 16 engaging, the threaded post 15... One end of the side surface of the blade body 15 is rotatably connected to the through hole 17 and the side surface of the extrusion block 12. The extrusion block 12 is trapezoidal. A rotating component 8 is fixedly connected to one end of the side surface of the threaded column 15 away from the extrusion block 12. A connecting block 9 is provided near the recess of the rotating component 6. The blade body 5 is fixedly connected to the side surface of the connecting block 9. A label sticker 14 is glued to the side surface of the blade body 5 away from the connecting seat 4. A fixing hole 18 is opened on the side surface of the blade body 5 away from the center. There are multiple fixing holes 18. A heat dissipation hole 7 is opened on the side surface of the blade body 5 away from the label sticker 14. A first threaded hole 11 is opened on the side surface of the connecting seat 4 away from the connecting base 1. There are multiple first threaded holes 11. The first threaded holes 11 correspond to the fixing holes 18. The high-speed steel blade body 5 is known for its excellent hardness, wear resistance and heat resistance, and is suitable for cutting paper tubes with high hardness. The blade body 5 can be initially installed by using external fixing bolts to cooperate with the fixing holes 18 and the first threaded holes 11.

[0024] The outer arc surface of the rotating component 8 is textured with recessed patterns. The area near the recessed patterns on the outer arc surface of the rotating component 8 is made of natural rubber. There are multiple mounting holes 3. The label sticker 14 is circular. The blade body 5 is made of high-speed steel. The lower surface of the connecting base 1 has a mounting groove, within which an anti-slip pad 2 is fixedly connected. The connecting base 1 is T-shaped, and mounting holes 3 are located on its upper surface near the bottom. Driven by an external motor, the rotating roller begins to rotate, which in turn drives the paper tube fixed to its surface to rotate synchronously. When the rotating paper tube reaches the position of the blade body 5, the paper tube can be cut.

[0025] The side surface of the blade body 5 near the connecting seat 4 is made of magnetic material, the contact surface of the connecting seat 4 near the blade body 5 is made of iron, the anti-slip pad 2 is made of natural rubber, and the connecting block 9 is convex in shape. The function of the heat dissipation hole 7 is to increase the contact area between the blade and the surrounding air, so that the heat generated by the heat dissipation hole 7 during the cutting process can be dissipated more quickly.

[0026] Working Principle: In use, first, the connecting base 1 is fixed to the worktable by using the external connector and mounting hole 3. During operation, the external motor drives the rotating roller, causing the paper tube to rotate. The blade body 5 contacts the rotating paper tube, allowing for cutting. When disassembling and maintaining the blade body 5, first remove the fixing bolts in the fixing hole 18 and the first threaded hole 11 to release the initial fixation. Then, rotate the rotating component 8 clockwise. The threaded column 15 drives the extrusion block 12 away from the through hole 17, and its inclined surface separates from the inclined surface of the second threaded hole 16. At this time, the rotating component 6 near the bottom of the connecting seat 4 loses its force. Under the action of gravity, the rotating component 6 rotates a certain angle vertically, while the rotating shaft 13 rotates within the connecting seat 4. The protrusion of the rotating component 6 disengages from the recess of the connecting block 9, completing the disassembly. When reinstalling after maintenance, place the connecting block 9 between the rotating components 6 and rotate the rotating component 8 counterclockwise. The extrusion block 12 approaches the through hole 17, and the inclined surface of the rotating component 6 gradually contacts the inclined surface of the extrusion block 12. With the help of the rotating shaft 13, the rotating part 6 gradually approaches and limits the connection block 9. Finally, the external bolt is used to pass through the fixing hole 18 and engage with the first threaded hole 11 to complete the fixed installation. Through the cooperation of the two fixing methods, the blade is ensured to remain stable during operation.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
