[0002] Fully automatic slitting and slitting machines can precisely slit and strip a variety of roll materials (such as paper, film, and aluminum foil), and are widely used in industries such as papermaking, printing, packaging, and tobacco. In cigarette packaging roll production, fully automatic slitting and slitting machines are primarily used to process wrapping paper and aluminum foil. The inner and outer wrapping papers of cigarettes must be processed by slitting and slitting machines into sheets of specific widths and lengths to meet the needs of packaging machinery. These sheets must exhibit high flatness and precision to ensure the packaging's aesthetics and seal. Some cigarette packaging uses aluminum foil as an inner lining or decorative layer, and this too must be processed by slitting and slitting machines into the appropriate size and shape. Special care must be taken to avoid scratches and creases during slitting and slitting to ensure good barrier properties and aesthetics.

[0003] Based on the above situation, in the prior art, the patent with publication number CN210233164U discloses an automatic paper roll slitting machine, including a base, a lifting motor and an axle seat three, a lifting motor is provided on the right side of the upper end of the base, a rotating shaft one is provided at the left end of the lifting motor, a bevel gear one is provided at the left end of the rotating shaft one, the bevel gear one engages with the bevel gear two, a screw rod is provided on the lower end of the screw rod, an axle seat one is installed, a lifting plate is provided on the screw rod, a motor chamber is provided on the left side of the lifting plate, a cutting motor is provided in the motor chamber, a rotating shaft two is provided at the left end of the cutting motor, a number of cutting blades are provided on the rotating shaft two, a shaft seat two is installed at the left end of the rotating shaft two, and the left end of the shaft seat two is fixedly connected to the lifting plate.

The left side of the tension detection roller 52 is provided with a second guide roller 51 rotatably mounted on the frame 1, and the right side of the tension adjustment roller 53 is provided with a third guide roller 54 mounted on the frame 1.

[0023] The utility model realizes the full automation from coil unwinding to slitting, tension adjustment and then winding through the coordinated work of various components, thereby improving production efficiency. The frame 1 serves as the supporting structure of the entire equipment, and the roller shaft at one end of the unwinding roller 2 and the roller shaft at one end of the winding roller 6 are respectively rotatably mounted on the frame 1, and the roller shaft of the unwinding roller 2 is connected to the power output shaft of the first power motor 7 installed on the frame 1, and the roller shaft of the winding roller 6 is connected to the power output shaft of the second power motor 8 installed on the frame 1.

[0024] As a preferred embodiment of the present invention, Figure 2 As shown, one end of the rotating shaft of the slitting knife roller 41 is fixedly sleeved with a first gear 42, and the rotating shaft of the anvil roller 44 is provided with a second gear 45 fixedly sleeved on the same side end of the first gear 42. The rotating shaft of the slitting knife roller 41 is provided with a drive motor 43 on one side of the first gear 42, and the power output shaft of the drive motor 43 is connected to the rotating shaft of the slitting knife roller 41, and the first gear 42 is engaged and rotated with the second gear 45.

[0025] The power output shaft of the drive motor 43 is directly connected to the rotating shaft of the slitting knife roller 41, and the rotating shaft of the slitting knife roller 41 is the rotating shaft 411. When the drive motor 43 is started, the rotational power generated by the drive motor 43 is directly transmitted to the slitting knife roller 41, causing it to start rotating. A first gear 42 is fixedly sleeved on the rotating shaft 411 of the slitting knife roller 41, and a second gear 45 meshing with the first gear 42 is fixedly sleeved on the rotating shaft of the anvil roller 44. When the slitting knife roller 41 rotates, the anvil roller 44 is driven to rotate synchronously through the meshing action of the first gear 42 and the second gear 45. As the slitting knife roller 41 and the anvil roller 44 rotate synchronously, the cutting circular knife 416 installed on the surface of the slitting knife roller 41 will rotate accordingly and form a shearing action with the surface of the anvil roller 44. When the packaging roll passes between the two rollers, it will be cut by the cutting circular knife 416 according to the set spacing.

[0026] As a preferred embodiment of the present invention, Figures 1 to 5 As shown, the axis of the cutting circular knife 416 passes through the installation channel 410, and the edge position of the installation channel 410 is provided with a rotationally symmetrically distributed sliding channel 415, and the end faces on both sides of the cutting circular knife 416 are surrounded by a fixing ring 417 with the same shape as the installation channel 410, and the fixing ring 417 is provided with a transversely penetrating fixing hole 419 at the position of the sliding channel 415; the axis of the cutting circular knife 416 passes through the installation channel 410, and the edge position of the installation channel 410 is provided with a rotationally symmetrically distributed sliding channel 415, and the end faces on both sides of the cutting circular knife 416 are surrounded by a fixing ring 417 with the same shape as the installation channel 410, and the fixing ring 417 is provided with a transversely penetrating fixing hole 419 at the position of the sliding channel 415.

[0027] The slitting knife roller 41 is provided with a rotating shaft 411 and a fixed shaft 412 fixedly sleeved on the outside of the rotating shaft 411, and a sliding bar 413 is arranged parallel to the upper and lower surfaces of the surface of the fixed shaft 412, and the sliding bar 413 is arranged along the length direction of the fixed shaft 412, and the sliding bar 413 is provided with a plurality of fixed channels 414 passing through along the width direction, and the fixed channels 414 are arranged equidistantly along the length direction of the sliding bar 413, and the cutting circular knife 416 is movably sleeved on the outside of the fixed shaft 412 and the sliding bar 413 through the installation channel 410, and the sliding bar 413 is placed in the sliding channel 415, and the fixing through hole 419 and the fixed channel 414 are coaxially penetrated by a fixing bolt 418, and the cutting circular knife 416 is fixed to the fixed shaft 412 by the fixing bolt 418.

[0028] The cutting circular knife 416 is movably connected to the fixed shaft 412 and the outside of the sliding bar 413 of the slitting knife roller 41 through the installation channel 410 through its axis.

The fixing through hole 419 on the fixing ring 417 is coaxially connected with the fixed channel 414 on the sliding bar 413 through the fixing bolt 418, so that the cutting circular knife 416 is firmly fixed on the fixed shaft 412. When the spacing between the cutting circular knives 416 needs to be adjusted, first loosen the fixing bolt 418 so that the cutting circular knife 416 can slide freely in the sliding channel 415 of the sliding bar 413. After pushing the cutting circular knife 416 to the desired position, re-tighten the fixing bolt 418 to adjust the spacing.

[0029] The rotating shaft 411 of the slitting knife roller 41 is rotatably mounted on the frame 1, and one end of the rotating shaft 411 of the slitting knife roller 41 is fixedly sleeved with a first gear 42, and the first gear 42 is engaged and rotated with the second gear 45 on the rotating shaft of the anvil roller 44. The power output shaft of the drive motor 43 is connected to the rotating shaft 411 of the slitting knife roller 41 to drive it to rotate. As the slitting knife roller 41 rotates, the cutting circular knife 416 forms a shearing effect with the anvil roller 44 to slit the passing packaging roll. The synchronous rotation of the slitting knife roller 41 and the anvil roller 44 is achieved through gear transmission, thereby ensuring the accuracy and stability of slitting.

[0030] Sliding bar 413 is arranged along the length of fixed shaft 412, providing stable support and guidance for circular cutting blade 416. The circular cutting blade 416 slides within sliding channel 415 of sliding bar 413 to adjust the spacing. Fixed channel 414 on sliding bar 413 mates with fixed through-hole 419 on fixed ring 417, and fixing bolt 418 secures circular cutting blade 416 to fixed shaft 412.

[0031] The method for adjusting the spacing of the circular cutting blades 416 involves first loosening the fixing bolts 418 to disengage them from the fixing holes 419 of the fixing ring 417 of the circular cutting blade 416 and the fixing channels 414 of the sliding bar 413. The circular cutting blade 416 is then pushed, and the sliding channels 415 thereon are used to slide along the sliding bar 413 until the circular cutting blades 416 are adjusted to the desired spacing. After the adjustment is completed, the fixing holes 419 of the fixing ring 417 are realigned with the fixing channels 414 of the sliding bar 413, and the fixing bolts 418 are sequentially passed through these holes and tightened to fix the position of the circular cutting blades 416 on the fixed shaft 412, thereby completing the spacing adjustment.

[0032] As a preferred embodiment of the present invention, Figures 1 to 3As shown, a mounting frame 55 and a lifting electric cylinder 56 are provided below the tension adjusting roller 53, a mounting shaft 59 is provided inside the tension adjusting roller 53, the tension adjusting roller 53 rotates around the mounting shaft 59, the tension adjusting roller 53 is fixedly mounted on the mounting frame 55 through the mounting shaft 59, the cylinder end of the lifting electric cylinder 56 is connected to the inner bottom surface of the frame 1, and the telescopic rod end of the lifting electric cylinder 56 is connected to the mounting frame 55, and the surfaces of both ends of the mounting shaft 59 of the tension adjusting roller 53 are symmetrically provided with first fixed slots 58 on the upper and lower sides, and the top and bottom of the lifting channel 11 are provided with second fixed slots 50 vertically opposite to the first fixed slots 58, and a spring 57 is provided between the first fixed slot 58 and the second fixed slot 50, and the two ends of the spring 57 are respectively abutted against the first fixed slot 58 and the second fixed slot 50.

[0033] The tension adjustment roller 53 is fixedly mounted on the mounting frame 55 through the mounting shaft 59. The tension adjustment roller 53 can rotate freely on the mounting shaft 59. The ends of the mounting shaft 59 are placed in the lifting channel 11. When the tension of the material needs to be adjusted, the telescopic rod of the lifting electric cylinder 56 is extended or shortened, thereby driving the mounting frame 55 and the tension adjustment roller 53 to rise or fall, thereby changing the tension of the material when passing through. The tension detection roller 52 can ensure that the material maintains a constant tension during the slitting process by monitoring the tension value in real time. The cooperation of the first fixed slot 58, the second fixed slot 50 and the spring 57 allows the tension adjustment roller 53 to automatically adapt to different positions during the vertical adjustment process, reducing tension fluctuations caused by position deviation. The setting of the spring 57 not only enhances the stability of the structure, but also can buffer the impact and vibration generated by the tension adjustment roller 53 during the adjustment process to a certain extent, protecting the equipment and materials from damage.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
