Description

Technical Field

[0001] The present application relates to the technical field of paper processing equipment, and in particular to a double-rotor spiral high-speed roll slitting machine. Background Art

[0002] Traditional single-rotor roll slitting machines usually adopt a single rotating shaft design and are equipped with straight-blade cutting tools to achieve paper cutting operations. The advantages of this method are simple structure and easy maintenance. However, it also has obvious limitations, such as the inability to accurately adjust the length of each cut, and it is difficult to ensure the size consistency between different batches on a continuous production line. Although there are also commonly adopted methods including but not limited to increasing motor power to increase speed, optimizing blade material and shape to improve cutting performance, multi-axis linkage mechanism or adding auxiliary conveyor belts. These improvement measures have indeed improved the performance of single-rotor roll slitting machines to a certain extent, but they still cannot completely overcome their inherent defects - that is, it is difficult to accurately adjust the length of each cut, resulting in the long-term problem of poor size consistency between different batches. Summary of the invention

[0003] In order to improve the speed and accuracy of paper slitting, achieve more regular stacking of paper after slitting, and avoid material waste or damage caused by improper stacking, the present application provides a dual-rotor spiral high-speed roll slitting machine.

[0004] The present application provides a dual-rotor spiral high-speed roll slitting machine, which adopts the following technical solution: A double-rotor spiral high-speed roll slitting machine comprises a frame, an embossing mechanism for pressing patterns and adjusting cutting length, a slitting mechanism for slitting paper, a discharging mechanism for conveying finished paper, and a stacking mechanism for arranging the stacked state of paper. The embossing mechanism, the slitting mechanism, the discharging mechanism and the stacking mechanism are sequentially installed on the frame, one end of the slitting mechanism is connected to the embossing mechanism, and the other end is connected to the discharging mechanism, and the edge of the discharging mechanism is connected to the stacking mechanism; a trimming mechanism for repairing paper is provided on the frame, and the trimming mechanism is installed on one side of the embossing mechanism.

[0005] By adopting the above technical solution, the dual-rotor spiral high-speed drum slitting machine can significantly improve the speed and accuracy of paper slitting. Specifically, the embossing mechanism achieves precise control of the paper cutting length by adjusting the cutting length, thereby improving the consistency of size between different batches. The slitting mechanism utilizes two relatively rotating slitting cylinders and the first and second rotating parts inside them, which cooperate with the sliding mechanism to ensure the precise cutting of paper at high efficiency and reduce the scrap rate. The discharging mechanism promptly transports the finished paper to the stacking mechanism, ensuring that the slitting mechanism works stably without paper jams and that the finished paper is neatly stacked. The stacking mechanism further arranges the stacking state of the paper, making the final product more neat and orderly, and avoiding material waste or damage caused by improper stacking. The trimming mechanism improves the overall quality of the finished paper by trimming the edges of the paper, making it more in line with actual use requirements.

[0006] Preferably, a feeding assembly is provided on the frame, and the feeding assembly is installed on the frame. The feeding assembly is used to convey the roll paper and adjust the roll feeding tension.

[0007] By adopting the above technical solution, the feeding assembly can effectively convey the roll paper and adjust the roll feeding tension, ensuring the stability and flatness of the paper before entering the slitting area, thereby improving the accuracy and efficiency of the subsequent slitting process.

[0009] By adopting the above technical solution, the feeding stability and smoothness of the roll paper are improved. Specifically, the sliding connection design between the feed guide pin and the feed slide allows the feed slide to move smoothly along the predetermined path, ensuring the accurate feeding of the roll paper. The clamping drive drives the feed slide to slide, realizing the precise positioning and adjustment of the roll paper position, further improving the control accuracy during the feeding process. The roll paper is firmly clamped by the clamp and driven to rotate by the feed drive, effectively preventing the paper from loosening or slipping during the feeding process, thereby ensuring the quality and efficiency of the subsequent slitting operation.

[0010] Preferably, the slitting mechanism includes a slitting cylinder rotatably mounted on the frame, a slitting drive member driving the slitting cylinder to rotate, a first rotating member rotatably mounted in the slitting cylinder, a second rotating member rotatably mounted in the slitting cylinder, a stator drive member driving the first rotating member to rotate, and a cutting member for slitting paper; the slitting drive member is mounted on the frame, and one end of the slitting cylinder is connected to the slitting drive member; the second rotating member is transmission-connected to the first rotating member; the stator drive member is fixedly mounted on one end of the slitting cylinder, and one end of the first rotating member is connected to the stator drive member; the cutting member is slidably mounted on the slitting cylinder, and one end of the cutting member abuts against the second rotating member, and the other end passes through the slitting cylinder to be exposed outside the cylinder.

[0011] By adopting the above technical scheme, efficient and accurate slitting of paper in a dual-rotor spiral high-speed drum slitting machine is achieved. Specifically, the combination of the slitting drum and the slitting drive ensures the stable operation of the slitting mechanism and improves the slitting speed and efficiency. The transmission connection between the first rotating member and the second rotating member enables the two rotors to operate synchronously at different speeds, enhances the stability of the slitting process, and cooperates with the slidable cutting member to ensure the accurate cutting of paper at high efficiency and reduce the scrap rate. The stator drive member drives the first rotating member to rotate, further improving the slitting accuracy. The cutting member is slidably installed on the slitting drum and abuts against the second rotating member. During the rotation of the second rotating member around the first rotating member, the cutting member is intermittently driven to slide, so that the cutting member moves down to cut the paper, which can achieve rapid cutting of the paper, flush paper cuts and accurate paper cutting, and reduces the cutting error and uneven cuts caused by mechanical vibration instability. The above scheme significantly improves the speed and accuracy of paper slitting, ensuring the continuity of production and consistency of quality.

[0013] By adopting the above technical solution, the first elastic member can provide continuous elastic support for the cut piece, ensuring that the cut piece always maintains a stable contact pressure during the cutting process, thereby improving the accuracy and stability of paper slitting. At the same time, this design can also effectively reduce the displacement of the cut piece caused by external interference, further improving the slitting quality and efficiency.

[0015] By adopting the above technical solution, the embossing mechanism can accurately adjust the cutting length to ensure the size consistency and stability of each piece of paper. Specifically, the coordinated use of the embossing part and the clamping and feeding part enables the paper to be accurately positioned and transported when entering the slitting area, thereby improving the accuracy and efficiency of paper slitting.

[0019] By adopting the above technical solution, the clamping member can effectively limit the jumping and deviation of paper during the conveying process, ensuring the smooth transmission of paper. Specifically, the clamping frame is rotatably connected to the frame, so that the clamping member can adapt to papers of different thicknesses, increasing the flexibility and scope of application of the equipment. The downward pressing part is composed of multiple groups and installed at intervals on the clamping frame, which can disperse the pressure more evenly and prevent the deformation or damage of the paper due to excessive local force. The design of the fine-tuning part allows fine adjustment of the downward pressing distance, improves the control accuracy, and further enhances the stability of paper transportation. The second elastic member applies elastic pressure to the clamping frame, so that the clamping member always maintains an appropriate contact force, and can maintain a good clamping effect even when the thickness of the paper changes, thereby avoiding quality problems caused by paper jumping.

[0028] The inventors of the present application have discovered that conventional single-rotor roll slitting machines usually adopt a single rotating shaft design and are equipped with a straight-blade cutting tool to achieve paper cutting operations. The advantages of this method are simple structure and easy maintenance. However, it also has obvious limitations, such as the inability to accurately adjust the length of each cut, and it is difficult to ensure the dimensional consistency between different batches on a continuous production line. To this end, the present application mainly adopts a dual-rotor spiral high-speed roll slitting machine, which achieves the effect of improving the speed and accuracy of paper slitting and achieving a more regular stacking effect after paper slitting. The present application is further described in detail below.

[0029] The present application provides a dual-rotor spiral high-speed roll slitting machine, see Figure 1 and Figure 2 , including a frame 1, an embossing mechanism 2 for embossing patterns and adjusting cutting length, a slitting mechanism 3 for slitting paper, a discharging mechanism 4 for conveying finished paper, and a stacking mechanism 5 for arranging the stacked state of paper. The embossing mechanism 2, the slitting mechanism 3, the discharging mechanism 4 and the stacking mechanism 5 are sequentially installed on the frame 1, one end of the slitting mechanism 3 is connected to the embossing mechanism 2, and the other end is connected to the discharging mechanism 4, and the edge of the discharging mechanism 4 is connected to the stacking mechanism 5; the frame 1 is provided with a trimming mechanism 8 for repairing paper, and the trimming mechanism 8 is installed on one side of the embossing mechanism 2.

[0030] Specifically, the embossing mechanism 2 includes an embossing member 21 for adjusting the cutting length, a clamping member 22 for cooperating with the embossing member 21 to clamp the paper, an embossing driving member 23 for driving the embossing member 21 to rotate, and a clamping driving member 24 fixedly mounted on the frame 1. The clamping member 22 is rotatably mounted on the frame 1, and one end of the clamping member 22 is connected to the clamping driving member 24; the embossing member 21 is rotatably mounted on the frame 1, and one end of the clamping member 22 is connected to the embossing driving member 23. The clamping member 22 can be a rubber clamping roller or a metal gear. The former is suitable for soft paper, and the latter is suitable for hard paper. The cooperation between the clamping member 22 and the embossing member 21 can be achieved through gear transmission or belt transmission to ensure that the two move synchronously and reduce the risk of deformation and tearing of paper during transmission.

[0031] See also Figure 2 and Figure 3 The embossing member 21 includes an embossing cylinder, which is rotatably mounted on the frame 1. The embossing cylinder is provided with a plurality of annular grooves. In other embodiments, it may be a pressing roller with protrusions.

When the embossing servo motor is working, the first gear rotates under the drive of the embossing servo motor, the first gear drives the second gear to rotate, the second gear drives the third gear to rotate, and the third gear drives the clamping cylinder to rotate, thereby realizing the synchronous rotation of the embossing member 21 and the clamping member 22. The cooperation between the clamping member 22 and the embossing member 21 is realized through gear transmission, which ensures the synchronous movement of the two and reduces the risk of deformation and tearing of paper during transmission. At the same time, the number of revolutions of the embossing member 21 driven by the embossing servo motor reflects the length of the paper fed into the slitting mechanism 3.

[0062] The working principle of a dual-rotor spiral high-speed roll slitting machine of the present application is as follows: By setting up the embossing mechanism 2, the slitting mechanism 3, the discharging mechanism 4 and the stacking mechanism 5, high efficiency, precision and stability are achieved in the paper processing process. The embossing mechanism 2 ensures that the paper can maintain a stable shape when entering the slitting area by adjusting the cutting length, reducing the risk of deformation and tearing of the paper during transportation. The slitting mechanism 3 can operate synchronously at different speeds through the dual-rotor design, ensuring that the paper can maintain a stable state when entering the slitting area, improving the speed and accuracy of slitting. The discharging mechanism 4 ensures that the paper is flat and wrinkle-free during transportation through a multi-level conveying and pressing design, avoiding quality problems caused by jumping and offset. The stacking mechanism 5 realizes neat stacking of paper through intelligent tray movement, avoiding material waste or damage caused by improper stacking. The trimming mechanism 8 ensures the neatness and beauty of the paper edge through precise trimming action, improving the overall quality of the product. By adding the feed assembly 9, the input quality and stability of the paper are further improved. In summary, this embodiment not only solves the technical problems existing in the traditional single-rotor roll slitting machine, but also innovates and optimizes in many aspects, significantly improving the performance and reliability of the paper processing equipment.
