An inclined block 15 is sleeved on the outer surface of the threaded rod 14. A ball bead 16 is slidably connected inside the rotating shaft 13. The ball bead 16 is in contact with the inclined block 15. A slitting knife 17 is sleeved on the outer surface of the rotating shaft 13. The ball bead 16 is clamped inside the inner surface of the slitting knife 17. Inside the device main body 11, there is a fixedly connected driving mechanism. The driving mechanism includes a driving motor 18. The driving motor 18 is fixedly connected inside the device main body 11.

A clamping groove 22 is opened inside the rotating shaft 13. The clamping block 21 is clamped inside the clamping groove 22. Before performing a cutting operation on the paper with the slitting knife 17 (at this time, the driving motor 18 is in an unstarted state), remove the mounting seat 12 at one end, and externally rotate the threaded rod 14. During the rotation of the threaded rod 14, the inclined block 15 is driven to slide outwards. At this time, the ball bead 16 loses the limit of being squeezed by the inclined block 15 and can slide inwards and contract. At this time, the slitting knife 17 can be pulled out for replacement. By rotating the threaded rod 14, the clamping and fixing of the slitting knife 17 can be completed. Different specifications and shapes of slitting knives 17 can be replaced more conveniently according to different slitting requirements, which is beneficial to improving the convenience of the replacement operation. When installing the slitting knife 17, sleeve the slitting knife 17 on the rotating shaft 13. At this time, the clamping block 21 is squeezed and contracted by the rotating shaft 13. Slide the slitting knife 17 along the outer surface of the rotating shaft 13. When the clamping block 21 slides into the clamping groove 22, the spring 19 drives the clamping block 21 to slide outwards and be clamped inside the clamping groove 22, so as to more intuitively and conveniently find the installation position of the slitting knife 17, which is beneficial to improving the accuracy of installation positioning.

[0029] Inside the device main body 11, a unwind roller 23 is rotatably connected. At one end of the device main body 11 close to the unwind roller 23, two bearing seats 24 are fixedly connected. Inside both of the two bearing seats 24, a pressure roller 25 is rotatably connected. On the outer surfaces of the two bearing seats 24, a photoelectric sensor 26 is fixedly connected. Inside the device main body 11, two cylinders 27 are fixedly connected. The two cylinders 27 are respectively fixedly connected to the lower ends of the two bearing seats 24.

When the edge position of the paper deviates from the predetermined track, the probe will sense this deviation and send out a feedback signal). When the laser paper shows a deviation, the signal is transmitted to the control box inside the device main body 11 (the control box includes a signal receiving module, a signal processing module, a feedback signal module and a control programming module). At this time, the cylinder 27 is started to drive the bearing seat 24 to move up and down. By changing the distance between the two pressure rollers 25, the tension is adjusted, so that the tension can be kept within an appropriate range to ensure the flatness and accuracy of slitting, and at the same time reduce the stretching deformation of the paper.

[0030] At one end of the device main body 11 close to the rotating shaft 13, a guide roller 28 is rotatably connected.

The laser paper roll to be slit is placed on the device main body 11. The device main body 11 (the device main body 11 includes a drive motor and a control box). The laser paper is passed through between the two pressure rollers 25. Uniform pressure is applied to the laser paper by the two pressure rollers 25 to ensure that the material remains flat during the slitting process and avoid wrinkles or irregular tension distribution. When the laser paper passes through the rotating shaft 13, the rotating shaft 13 is driven to rotate by the drive motor 18, and the rotating shaft 13 drives the slitting knife 17 to rotate to slit the laser paper. The slit laser paper is respectively sleeved outside the two air shafts 29 through the guiding and positioning of the guide roller 28. The two air shafts 29 rotate to wind it up for subsequent use. The dust suction pipe 31 can be connected to a vacuum cleaner. The dust suction pipe 31 is located between the slitting knife 17 and the guide roller 28. The paper scraps and dust generated by slitting are timely sucked through the dust suction pipe 31 to keep the working environment clean and at the same time avoid interfering with the slitting accuracy.

[0031] In view of the problems existing in the prior art, the utility model provides a slitter for processing positioning laser paper. Before the paper is cut by the slitting knife 17, the mounting seat 12 at one end is removed. The threaded rod 14 is screwed outwards. During the rotation of the threaded rod 14, the inclined block 15 is driven to slide outwards. At this time, the ball bead 16 loses the limit of being squeezed by the inclined block 15 and can slide inwards and contract. At this time, the slitting knife 17 can be pulled out for replacement. By screwing the threaded rod 14, the slitting knife 17 can be clamped and fixed. Different specifications and shapes of slitting knives 17 can be replaced more conveniently according to different slitting requirements, which is beneficial to improving the convenience of the replacement operation.

[0032] Working principle:

[0033] First step, place the laser paper roll to be slit on the device main body 11 (the device main body 11 includes a driving motor and a control box). Pass the laser paper through between the two pressure rollers 25. Apply uniform pressure to the laser paper through the two pressure rollers 25 to ensure that the material remains flat during the slitting process and avoid wrinkles or irregular tension distribution. When the laser paper passes through the rotating shaft 13, the rotating shaft 13 is driven to rotate by the driving motor 18, and the rotating shaft 13 drives the slitting knife 17 to rotate to slit the laser paper. The slit laser paper is guided and positioned by the guide roller 28 and sleeved outside the two air shafts 29 respectively. The two air shafts 29 rotate to wind it up for subsequent use. The dust suction pipe 31 can be connected to a vacuum cleaner. The dust suction pipe 31 is located between the slitting knife 17 and the guide roller 28. The dust suction pipe 31 timely sucks away the paper scraps and dust generated by the slitting to keep the working environment clean and avoid interfering with the slitting accuracy at the same time.

[0034] Step 2: Before the paper is cut by the cutting knife 17 (at this time, the driving motor 18 is in an unstarted state), remove the mounting seat 12 at one end. The mounting seat 12 is fixed in the device main body 11 by bolts. Rotate the threaded rod 14 outwards (both ends of the rotating shaft 13 are hollow rings, and the rings at both ends of the rotating shaft 13 are sleeved in the mounting seat 12. The threaded rod 14 rotates inside the rotating shaft 13, so there will be no movement interference with the mounting seat 12). During the rotation of the threaded rod 14, the inclined block 15 is driven to slide outwards. At this time, the ball bead 16 loses the limit of being squeezed by the inclined block 15 and can slide inwards and contract. At this time, the cutting knife 17 can be pulled out for replacement. By rotating the threaded rod 14, the clamping and fixing of the cutting knife 17 can be completed. Different specifications and shapes of cutting knives 17 can be replaced more conveniently according to different cutting requirements, which is beneficial to improving the convenience of replacement operation. When installing the cutting knife 17, the cutting knife 17 is sleeved outside the rotating shaft 13. At this time, the clamping block 21 is squeezed and contracted inwards through the rotating shaft 13, and the cutting knife 17 slides along the outer surface of the rotating shaft 13. When the clamping block 21 slides into the card slot 22, under the action of the spring 19, the clamping block 21 is driven to slide outwards and is clamped in the card slot 22, so as to more intuitively and conveniently find the installation position of the cutting knife 17, which is beneficial to improving the accuracy of installation positioning. When the laser paper is kept flat by being squeezed by two pressure rollers 25, the edge position of the laser paper is detected by the photoelectric sensor 26 installed on the bearing seat 24 (it detects the edge or mark of the paper by emitting a light beam, usually infrared or visible light. When the edge position of the paper deviates from the predetermined track, the probe will sense this deviation and send a feedback signal). When the laser paper deviates, the signal is transmitted to the control box in the device main body 11 (the control box includes a signal receiving module, a signal processing module, a feedback signal module and a control programming module). At this time, the air cylinder 27 is started to drive the bearing seat 24 to lift, and the distance between the two pressure rollers 25 is changed, so as to adjust the tension, so that the tension can be kept within an appropriate range to ensure the flatness and accuracy of cutting, and at the same time reduce the stretching deformation of the paper.

For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
