Specific implementation

[0055] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0056] Embodiment 1:

[0057] As Figures 1 to 6 shown, the paper roll slitting machine provided by the embodiment comprises a paper roll unwinding device for unwinding, a casing 1, a conveying device arranged in the casing 1 for conveying the paper roll, a slitting mechanism arranged on the conveying device for slitting the paper roll, a driving device for driving the whole machine to run and a winding device for collecting the slitted paper roll. The paper roll unwinding device is arranged on the side away from the casing 1, is a paper roll unwinding machine, is an existing procurement equipment, belongs to an auxiliary slitting machine processing, belongs to a feeding device, is prior art and will not be introduced here. The equipment is also drawn in the drawing, and the specific equipment placement position is the side of the casing 1 (away from the slitting mechanism).

[0058] Specifically, the conveying device comprises two rotating base shafts 2 for power traction and a plurality of unpowered roller conveying rollers 3 for transition.

[0059] Specifically, the driving device comprises a motor one 4 and a transmission mechanism for driving the two rotating base shafts 2 to rotate.

[0060] The transmission mechanism includes a driving shaft 5 connected to the output end of the motor 4, two driven shafts 6 symmetrically arranged on both sides of the driving shaft 5, and a differential 7 arranged between the driving shaft 5 and the two driven shafts 6 for coordinating transmission. In the existing slitting machine, the speed adjustment of the winding shaft usually adopts a simple speed changing device, and two motors are used to drive two winding shafts respectively. Because two motors are used for control respectively, there is a certain speed difference between the two winding shafts, which leads to many defects in slitting precision and stability. For example, for some high-precision material slitting, the speed adjustment precision of the existing equipment is insufficient, which easily leads to uneven material slitting, irregular edges and other problems.

[0061] Specifically, the two half axle gears of the differential 7 are coaxial with the driving shaft 5, the two driven shafts 6 are in transmission connection with the two half axle gears through transmission belts and transmission sprockets, and the output ends of the two driven shafts 6 drive the two rotary base shafts 2 to rotate through transmission belts and transmission sprockets. The differential can automatically adjust the rotating speeds of the output shafts on both sides, so that the rotating speeds of the two driven shafts are the same even in the case of uneven load. This design not only improves the transmission precision of the slitting machine, but also enhances the stability and reliability of the equipment. Compared with the traditional scheme of using two independent motors for driving, this design is simpler and more efficient, and can effectively solve the problems of unevenness and irregular edges that may occur during high-precision material slitting.

[0062] In use, the motor 4 is started as a power source, and the power is transmitted to the differential 7 through the driving shaft 5. After receiving the power, the differential 7 evenly distributes the power to the two half axle gears through the planetary gear mechanism inside it, and the two half axle gears are connected to the two driven shafts 6 through transmission belts and transmission sprockets, thereby driving the two driven shafts 6 to rotate. Finally, the two driven shafts 6 drive the two rotary base shafts 2 to rotate synchronously through transmission belts and transmission sprockets.

[0063] In this process, even if the loads on the two rotary base shafts 2 are different, the differential 7 can automatically adjust the rotating speeds of the output shafts on both sides, ensuring that the rotating speeds of the two driven shafts 6 remain consistent. This design not only solves the problem of inconsistent rotating speeds of the two winding shafts in the traditional driving device, but also greatly improves the transmission precision and stability of the slitting machine.

[0064] Embodiment 2:

[0065] On the basis of embodiment 1, in order to solve the problem of inconvenient sharpening of the cutter.

[0066] The application further provides a paper roll slitting machine, which comprises a slitting mechanism, the slitting mechanism comprising a cutter shaft 8 and a plurality of cutters 9 arranged on the cutter shaft 8, the cutters 9 being detachably connected with the cutter shaft, and the spacing of the cutters 9 being adjusted by moving the cutters 9, so that different specifications of paper rolls can be cut according to the slitting requirements.

[0067] One side of the cutter shaft 8 is equipped with a sharpening mechanism for grinding the cutter 9, extending the service life of the cutter 9 and reducing the decline in slitting quality caused by cutter dulling. At the same time, since frequent disassembly of the cutter is unnecessary, the risk of cutter damage is reduced, improving the overall reliability and production efficiency of the equipment.

[0068] Specifically, the sharpening mechanism includes two sharpening frames 10 symmetrically arranged on the housing 1, a sharpening shaft 11 installed between the sharpening frames 10, and sharpening blocks 12 arranged on the sharpening shaft 11 and detachably connected to the sharpening shaft 11. The sharpening frames 10 are rotatably connected to the housing 1. The number of sharpening blocks 12 is the same as the number of cutting blades 9. Both the sharpening shaft 11 and the blade shaft 8 are equipped with scales with the same range. The material of the sharpening blocks 12 is diamond composite material. The spacing of the cutting blades 9 and the spacing of the sharpening blocks 12 can be accurately adjusted by the scales.

[0069] When the cutter 9 needs to be sharpened, the operator can adjust the angle of the sharpening frame 10 so that the sharpening blocks 12 contact the cutter 9. Then, the cutter 9 is sharpened by rotating. Since the number of sharpening blocks 12 is the same as the number of cutters 9, they correspond one-to-one, allowing all cutters 9 to be sharpened simultaneously, greatly improving efficiency. After sharpening, the angle of the sharpening frame 10 is adjusted so that the sharpening blocks 12 are moved away from the cutters 9.

[0070] Example 3:

[0071] Based on Example 2, in order to clean up the powder and excess paper strips generated during the slitting process, a cleaning mechanism for collecting slitting powder and excess paper strips is arranged on one side of the slitting mechanism.

[0072] Specifically, the cleaning mechanism includes a suction port structure arranged on one side of the cutter shaft 8 for collecting excess paper strips at the edge and paper dust generated during cutting, a storage box 13 communicating with the suction port structure, and a fan 15 arranged on the storage box 13. A filter screen 16 for blocking debris is arranged between the fan 15 and the storage box 13.

[0073] Specifically, the suction port structure includes a suction grille 17 arranged on one side of the cutter 9 and large suction ports 14 symmetrically arranged on both sides of the suction grille 17, which can effectively collect excess slit paper strips at the edges and paper dust generated during cutting.

[0074] This solution addresses the issue of cleaning up powder and excess paper strips generated during the slitting process, improving the cleanliness and efficiency of the slitting machine. Timely waste removal prevents accumulation that could affect slitting quality or machine operation, while also maintaining a clean working environment.

[0075] Furthermore, the cleaning mechanism of this application can be implemented in various ways. For example, the suction port structure can be designed with an adjustable shape to accommodate rolls of paper of different widths. The storage box can be made of transparent material for easy observation of waste collection. The fan can be a variable frequency speed control motor, adjusting the suction power according to actual needs. The filter can have a multi-layer structure to improve the filtration effect.

[0076] Example 4:

[0077] Based on implementation 3, uneven material thickness, tension variations, or other mechanical errors may cause a difference in the speed of the two take-up rollers during winding.

[0078] This application further proposes a roll paper slitting machine, including a winding device. Specifically, there are two winding devices, each including a winding roller 18 and a motor 19 that drives the winding roller 18 to rotate. A large steel roller 20 is arranged between the two winding rollers 18. During the slitting process, the two winding rollers 18 are close to the large steel roller 20. The large steel roller 20 is a non-powered roller, which reduces the impact of speed fluctuations or mechanical impacts on the winding rollers through its large inertia and buffering capacity.

[0079] The friction between the main roll 20 and the two take-up shafts 18 ensures that the two take-up shafts 18 rotate at the same speed. Assuming the two take-up shafts 18 are represented by axis A and axis B, when the speed of axis A is greater than the speed of axis B, the friction between axis A and the main roll 20 increases. Increased friction leads to increased resistance on axis A, causing its speed to decrease. Therefore, it ensures that axes A and B have the same speed. Because the friction between axes A and B is the same, the winding tension of axes A and B is also the same. This method avoids speed differences caused by delays in the electronic control system. The mechanical synchronization device is simple and reliable, and is especially suitable for slitting processes requiring extremely high speed synchronization accuracy.

[0080] Principle: The large mass of the large steel roller 20 acts as a buffer, absorbing instantaneous speed fluctuations caused by changes in material tension or mechanical vibration. This buffering function reduces instantaneous speed differences, ensuring smoother speeds for the two take-up rollers 18.

[0081] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
