[0040] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] Specific embodiment, combined with Figures 1 to 13 As shown, the technical solution of the present invention is further described. A slitting machine includes a frame 1 for supporting the overall structure. A slitting mechanism 2 for slitting a paper roll is provided within the frame 1. A feeding mechanism 3 for feeding the paper roll is provided on one side of the slitting mechanism 2. A reeling mechanism 4 for gathering the slit paper roll is provided on the other side of the slitting mechanism 2. A first tensioning device 5 is provided between the slitting mechanism 2 and the reeling mechanism 4 to maintain tension on the slit paper roll. The first tensioning device 5 can stabilize the tension of the slit paper roll, preventing the paper roll from wrinkling or being damaged during the reeling process in the reeling mechanism 4. It ensures that the slit paper roll can be separated by a certain gap in the reeling mechanism 4, preventing multiple paper rolls from stacking together and affecting the reeling effect.

[0042] In this embodiment, the first tensioning device 5 includes a first roller 51 for stabilizing tension and separating the cut paper, and a second roller 52 corresponding to the first roller 51. The first roller 51 and the second roller 52 are located at different horizontal planes. As a preferred embodiment of this embodiment but not a limitation, the first roller 51 and the second roller 52 are arranged in parallel, and the second roller 52 is located on the lower right side of the first roller 51.

[0043] Furthermore, the first tensioning device 5 is provided with a mounting frame 53 for mounting the first roller 51 and the second roller 52, the first roller 51 is provided with a first rotating component 511 for rotation, the second roller 52 is provided with a second rotating component 521 for rotation, the mounting frame 53 is provided with a first mating component 531 mating with the first rotating component 511 and a second mating component 532 mating with the second rotating component 521, and the mounting frame 53 is connected to the frame 1.

[0044] Furthermore, as a preferred embodiment of this embodiment but not a limitation, the first roller 51 and the second roller 52 are both arc-shaped rollers. The first roller 51 and the second roller 52 can stabilize the tension of the paper roll after slitting, and at the same time separate the slit paper rolls by a certain gap before transferring them to the rewinding mechanism 4, thereby preventing multiple rolls of paper from being stacked together.

[0045] In this embodiment, a second tensioning device 6 for controlling the tension of the feeding paper roll is provided between the slitting mechanism 2 and the feeding mechanism 3. The second tensioning device 6 can ensure the tension of the feeding paper roll and facilitate the subsequent slitting of the paper roll.

[0046] Furthermore, the second tensioning device 6 includes a movable roller 61 for increasing the distance between rollers and a first cylinder 62 for driving the movable roller 61. By pushing the movable roller 61 through the first cylinder 62, the distance between the movable roller 61 and the adjacent paper roll conveying roller can be increased, thereby controlling the tension of the feeding paper roll.

[0047] Furthermore, as a preferred embodiment of this embodiment but not a limitation, the second tensioning device 6 includes a fixed shaft 63 connected to the frame 1, and both ends of the fixed shaft 63 are provided with movable shafts 64 connected to the movable roller 61, and the inner side of the movable shaft 64 is provided with a fulcrum 641 for connecting with the first cylinder 62. The first cylinder 62 drives the movable shaft 64 through the connection with the fulcrum 641, and then drives the movable roller 61 through the movable shaft 64, increasing the distance between the movable roller 61 and the adjacent roller for transmitting the roll paper, thereby stabilizing the tension of the loading roll paper and providing convenience for the subsequent slitting of the roll paper.

[0048] In this embodiment, the slitting mechanism 2 includes a guide roller 21 for supporting and guiding the roll of paper and a slitting roller 22 that cooperates with the guide roller 21 to slit the roll of paper. The slitting mechanism 2 also includes a first drive device 23 for providing power for the rotation of the guide roller 21 and the slitting roller 22.

[0049] Furthermore, first transmission members 24 are connected to both ends of the guide roller 21, and first gears 25 are connected to both ends of the slitting roller 22. A second gear 26 is connected to one side of the first gear 25, and a second transmission member 27 is coaxially connected to the second gear 26. A prime mover 28 is connected to one side of the first driving device 23. As a preferred embodiment of this solution but not a limitation, the prime mover 28, the first transmission member 24, and the second transmission member 27 are driven by a belt 29. The first transmission member 24 drives the guide roller 21 to rotate, and the second transmission member 27 drives the second gear 26 to rotate. The second gear 26 engages with the first gear 25, thereby driving the slitting roller 22 to rotate. At this time, the slitting roller 22 rotates in opposite directions to the guide roller 21, providing convenient slitting of the paper roll.

[0050] Furthermore, as a preferred implementation of this solution but not a limitation, the first driving device 23 is a motor installed on the inner side of the frame 1.

[0051] In this embodiment, the winding mechanism 4 includes a first transmission roller 41 and a second transmission roller 42 cooperating with the first transmission roller 41. The winding mechanism 4 includes a second drive device 43 for driving the first transmission roller 41 and the second transmission roller 42. The second drive device 43 can drive the loading, slitting, and winding processes of the paper roll, and the first transmission roller 41 and the second transmission roller 42 are both driven by the second drive device 43.

[0052] Furthermore, the winding mechanism 4 also includes a winding roller 44 for winding, one end of which is connected to a pressing device 45 for cooperating with the compression and winding. The pressing device 45 includes a piston rod 451 connected to the winding roller 44 and a second cylinder 452 for controlling the extension and retraction of the piston rod 451. The second cylinder 452 can press the winding roller 44 against the second transmission roller 42. As the second transmission roller 42 operates, the winding roller 44 is loaded with a paper core. After the paper sticks to the paper core, the second cylinder 452 presses the paper core downward. As the slitting machine operates, the winding roller 44 can rotate with the first transmission roller 41 and the second transmission roller 42, and the paper roll will continue to grow until it reaches the required paper roll size.

[0053] Furthermore, as a preferred implementation of this solution but not a limitation, the second driving device 43 is a motor installed on the outside of the frame 1.

[0054] Furthermore, as a preferred embodiment of this solution but not a limitation, the winding roller 44 is an inflatable shaft.

[0055] In this embodiment, one side of the feeding mechanism 3 is equipped with a feeding device 31 for feeding the paper roll and a correction device 32 for correcting the paper's direction. The correction device 32 includes a detection component 321 for detecting the paper roll and a correction component 322 corresponding to the detection component 321 for fine-tuning the paper roll. When the detection component 321 detects deviation in the paper roll, the correction device 322 can adjust the paper roll, thereby preventing inaccurate slitting or waste caused by deviation in the paper roll feeding. At the same time, continuous monitoring and immediate correction enhance production stability and reliability, reducing downtime caused by feeding deviation.

[0056] The working principle of this embodiment is as follows:

[0057] The utility model proposes a slitting machine, which can make the tension of the paper roll more stable during rewinding, and can separate the slit paper rolls by a certain distance to prevent the paper rolls from stacking together and affecting the rewinding of the paper rolls. The specific principle is as follows:

[0058] The second tensioning device 6 on one side of the feeding mechanism 3 can transmit the loaded paper roll and ensure its tension, and transmit it to the slitting mechanism 2 for slitting; the first transmission roller 41 and the second transmission roller 42 are driven by the second driving device 43, and the second cylinder 452 presses the winding roller 44 to rotate and rewind with the first transmission roller 41 and the second transmission roller 42, and the first driving device 23 drives the slitting mechanism 2 to implement the slitting of the paper roll. At the same time, a first tensioning device 5 is provided between the slitting mechanism 2 and the rewinding mechanism 4, wherein the first roller 51 and the second roller 52 can rotate with the transmission of the paper roll, thereby ensuring the tension of the paper after slitting, and at the same time, the arc-shaped roller separates the slitting paper rolls by a certain distance.
