Technical Field

[0001] This utility model belongs to the technical field of paper cutting equipment, specifically relating to a knife-dispensing device and a roll paper slitting machine. Background Technology

[0002] With the continuous progress and development of new technologies for pulp production both domestically and internationally, and the ever-growing demand for high-end products, not only have more sizes and specifications emerged, but also an increasing number of high-end paper products. In the paper production process, roll paper undergoes feeding, recurving, cutting, conveying, and collection in sequence to be processed into paper of the preset specifications.

[0003] Chinese patent document CN217417664U discloses an automated roll paper slitting machine, including a clamping mechanism, a first recurving mechanism, a slitting mechanism, a conveying mechanism and a paper receiving mechanism arranged sequentially along the conveying direction. The slitting mechanism includes a housing, inside which a longitudinal cutting section and a paper feeding drive mechanism are installed. The longitudinal cutting section includes a longitudinal transmission blade shaft, a transmission screw, and a drive motor. The input shaft of the transmission screw is connected to the output shaft of the drive motor, and a screw nut is slidably connected to the outer wall of the transmission screw. The paper longitudinal cutting section adopts a fully automatic blade arrangement, and the blade setting structure improves the degree of automation, reduces the harm to the human body during blade setting, and improves the blade life. Moreover, the longitudinally cut paper has no burrs, no serrations, and high paper size consistency. The tension of multiple conveyor belts can be adjusted individually according to the actual needs, reducing the purchase cost of conveyor belts and significantly improving the life of conveyor belts.

[0004] The blade arrangement device in the aforementioned patent document uses a screw drive method, requiring a corresponding drive screw for each upper longitudinal cutter. This design results in a larger overall size and more complex structure for the slitting machine, making it inconvenient to use and maintain, and affecting the production efficiency of paper products.

Detailed Implementation

[0020] like Figure 1 As shown, this embodiment provides a knife-cutting device applied in a roll paper slitting machine, including a first longitudinal cutting knife mechanism 1 and a second longitudinal cutting knife mechanism 2. The first longitudinal cutting knife mechanism 1 and the second longitudinal cutting knife mechanism 2 are both disposed on the frame 3 of the roll paper slitting machine. The first longitudinal cutting knife mechanism 1 is located above the second longitudinal cutting knife mechanism 2. When the roll paper passes through the gap between the first longitudinal cutting knife mechanism 1 and the second longitudinal cutting knife mechanism 2, the first longitudinal cutting knife mechanism 1 and the second longitudinal cutting knife mechanism 2 cooperate with each other to longitudinally cut the roll paper into strips of paper.

[0021] The first longitudinal cutting mechanism 1 includes a first guide rail 11 and a plurality of first longitudinal cutting blade assemblies. The first guide rail 11 is mounted on the frame 3. Each first longitudinal cutting blade assembly is equipped with a first driving mechanism for driving it to slide along the first guide rail 11. Each first driving mechanism drives the corresponding first longitudinal cutting blade assembly to move along the first guide rail 11, cooperating with the second longitudinal cutting mechanism 2, thereby longitudinally cutting the roll paper into strips of different widths.

[0022] like Figure 3 and Figure 4 As shown, the first driving mechanism includes a first driving member 12 and a first gear 13. The output end of the first driving member 12 is connected to the first gear 13. The first guide rail 11 has a first rack along its length, and the first rack meshes with the first gear 13. The first driving member 12 includes a first driving motor, which is mounted on the first longitudinal cutting blade assembly. The first driving motor drives the first gear 13 to rotate. Since the first gear 13 meshes with the first rack, the first longitudinal cutting blade assembly can move along the first guide rail 11 with the first driving motor.

[0023] This utility model designs a first rack on the first guide rail 11, with each first gear 13 meshing with the first rack. The first driving component 12 drives each first longitudinal cutting blade assembly to slide along the first guide rail 11, thereby adjusting the cutting width of the long strip of paper. Its structure is simple, effectively reducing the overall size of the slitting machine, facilitating the use and maintenance of the slitting machine, and helping to improve the production efficiency of paper products.

[0024] like Figure 4 As shown, in this embodiment, the first longitudinal cutting blade assembly includes a first circular blade 14, a telescopic adjustment member 15, and a first longitudinal cutting mounting base 16. The first circular blade 14 is connected to the movable end of the telescopic adjustment member 15, and the fixed end of the telescopic adjustment member 15 is connected to the first longitudinal cutting mounting base 16. The first longitudinal cutting mounting base 16 is slidably engaged with the first guide rail 11, and the first driving member 12 is mounted on the first longitudinal cutting mounting base 16. Preferably, the telescopic adjustment member 15 is a cylinder. The cylinder drives the first circular blade 14 to move up and down, causing the first circular blade 14 to move closer to or further away from the second circular blade 24 of the second longitudinal cutting blade mechanism 2, facilitating longitudinal cutting of the roll paper.

[0025] The first longitudinal cutting mechanism 1 further includes a first support plate 17, and each first longitudinal cutting mounting base 16 is connected to a first connecting strip. The first connecting strip is connected to a first cable chain 18, and the first cable chain 18 is disposed on the first support plate 17. The first support plate 17 is disposed on one side of the first guide rail 11, and each first cable chain 18 is placed on the first support plate 17.

[0026] like Figure 3 and Figure 5 As shown, in this embodiment, the second longitudinal cutting blade mechanism 2 includes a second guide rail 21 and a plurality of second longitudinal cutting blade assemblies. The second guide rail 21 is spaced apart from the first guide rail 11 on the frame 3, and the second guide rail 21 is located below the first guide rail 11. Each second longitudinal cutting blade assembly is equipped with a second driving mechanism for driving it to slide along the second guide rail 21. Specifically, the second driving mechanism includes a second driving member 22 and a second gear 23. The output end of the second driving member 22 is connected to the second gear 23. The second guide rail 21 is provided with a second rack along its length direction, and the second rack meshes with the second gear 23. The second driving member 22 includes a second driving motor, which is mounted on the second longitudinal cutting blade assembly. The second driving motor drives the second gear 23 to rotate. Since the second gear 23 meshes with the second rack, the second longitudinal cutting blade assembly can move along the second guide rail 21 with the second driving motor.

[0027] like Figure 5 As shown, the second longitudinal cutting blade assembly includes a second circular blade 24 and a second longitudinal cutting mounting base 25. The second circular blade 24 cooperates with the first circular blade 14 to longitudinally cut the roll paper into strips. The second circular blade 24 is connected to the second longitudinal cutting mounting base 25. The second longitudinal cutting mounting base 25 is slidably engaged with the second guide rail 21. The second driving member 22 is mounted on the second longitudinal cutting mounting base 25.

[0028] Preferably, the second longitudinal cutting mechanism 2 further includes a cutting shaft 26, which is mounted on the frame 3 and parallel to the second guide rail 21. Each second circular blade 24 slides with the cutting shaft 26, improving the movement stability of the second circular blade 24. Further, the second longitudinal cutting mechanism 2 also includes a second support plate 27. Each second longitudinal cutting mounting base 25 is connected to a second connecting strip, which is connected to a second drag chain 28. The second drag chain 28 is mounted on the second support plate 27. In this invention, the cutting shaft 26 is positioned between the first guide rail 11 and the second guide rail 21. When the second drive motor drives the second longitudinal cutting mounting base 25 to move along the second guide rail 21, the second circular blades 24 also slide along the cutting shaft 26, so that the position of the second circular blade 24 corresponds to the position of the first circular blade 14, thereby longitudinally cutting the roll paper into several strips of paper.

[0029] like Figure 1 As shown, this embodiment also provides a roll paper slitting machine, including the above-mentioned blade arrangement device, and also includes a frame 3. The frame 3 is provided with a paper traction device 4, which is located on one side of the blade arrangement device. The paper traction device 4 is used to traction the roll paper to achieve continuous production.

[0030] like Figure 2 As shown, specifically, the paper traction device 4 includes an upper traction roller 41, a lower traction roller 42, and a traction drive mechanism. The surface of the upper traction roller 41 has left and right spiral patterns with opposite directions. The traction drive mechanism is connected to the lower traction roller 42. The lower traction roller 42 and the upper traction roller 41 cooperate to pull the paper roll through the cutter device to achieve longitudinal cutting. The lower traction roller 42 is driven to rotate by the traction drive mechanism, and the paper is pulled and conveyed between the upper traction roller 41 and the lower traction roller 42. At the same time, the surface of the upper traction roller 41 has left and right spiral patterns with opposite directions, which can press the paper so that the paper unfolds from the middle to both sides, ensuring the flatness of the paper surface and achieving effective traction of the paper.
