Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of recycled kraft paper, in particular to a slitting device for producing recycled kraft paper. Background Art

[0002] A slitting device for recycled kraft paper production is used to cut recycled kraft paper rolls or sheets into required sizes. This equipment is usually used in the production line of recycled kraft paper to customize paperboard products of different specifications and sizes. Recycled kraft paper is an environmentally friendly special paper. Its production process uses recycled fibers or renewable materials to reduce the consumption of natural resources and the impact on the environment. It has the characteristics of high fixation, high stiffness, high ring pressure, and super moisture resistance.

[0003] After searching, a Chinese patent document with announcement number CN217494400U provides a high-efficiency paper cutter, which relates to the technical field of cutting equipment, including: a conveying component; a transmission component is arranged at the upper end of the right side of the conveying component, and a sliding component is slidably installed at the middle of the front and rear ends of the conveying component. After the conveying component conveys the paper to the specified position, the transmission component will trigger the swing block to swing downward to realize the transmission of the sliding component, so that the sliding component can run synchronously with the paper, and at the same time, the reset component on the cutting component will run along the bearing plate to realize the cutting of the paper. The sliding component driven by the swing block and the transmission wheel can make the cutting part stably follow the paper and make the equipment stably cut during the paper running, which solves the problem that the existing equipment needs to pause when cutting paper, resulting in reduced production efficiency. At the same time, the existing equipment that cuts during operation is prone to skew cutting and paper jams.

[0004] The beneficial effects of the above patent specification mentions that "the transmission component will trigger the swing block to swing downward, realize the transmission of the sliding component, and let the sliding component run synchronously with the paper. The running inner slider will trigger the lifting component and the reset component, so that the lifting component rotates to realize the overall descent of the carrier plate. At the same time, the reset component on the cutting component will run along the carrier plate to achieve the cutting of the paper. The sliding component driven by the swing block and the transmission wheel can make the cutting part stably follow the paper and make the equipment perform stable cutting during the operation of the paper." Although the above patent can use the transmission component, cutting component and carrier plate to achieve paper cutting, it is impossible to change the position of the cutting head to adapt to different cutting requirements during processing. Therefore, a slitting device for the production of recycled kraft cardboard is proposed to solve the above problems. Utility Model Content

A support plate is fixedly connected to the left side of the front end of the processing table 1, and the outside of the motor 2 18 is installed on the top of the support plate. The support plate can maintain the stability of the motor 2 18 during operation. The motor 2 18 is started, and the driving end of the motor 2 18 is fixedly connected with the active roller 19. The active roller 19 rotates under the drive of the motor 2 18, and the outer sleeve of the active roller 19 is provided with a conveyor belt 20. After the cutting is completed, as the conveyor belt 20 moves to the right, the active roller 19 will drive the conveyor belt 20 to operate under rotation. The right side of the processing table 1 is internally rotatably connected with a driven roller 21, and at the same time, the driven roller 21 is driven to rotate through the conveyor belt 20. The inner wall of the other end of the conveyor belt 20 is sleeved on the outside of the driven roller 21. At this time, the conveyor belt 20 will drive the jammed paper to move.

[0038] Working principle: first place the processing table 1 to a suitable position, then put the paper jam on the conveyor belt 20, then start the motor 2 18, and the active roller 19 rotates under the drive of the motor 2 18, and the active roller 19 will drive the conveyor belt 20 to operate under the rotation, and at the same time, the conveyor belt 20 will drive the driven roller 21 to rotate, and the conveyor belt 20 will drive the paper jam to move, and at the same time start the motor 1 3, and the threaded rod 4 rotates under the drive of the motor 1 3, and the threaded rod 4 will drive the connecting block 5 to move under the rotation, and the connecting block 5 will drive the adjustment plate 6 to slide on the inner wall of the limit groove 12 when moving, and the adjustment groove 7 will drive the limit column 8 to slide along the trajectory of the adjustment groove 7 When the limit column 8 slides, it will push the cutting plate 9 to slide on the outside of the connecting column 10, and the width between the cutting plates 9 can be changed by adjusting the position of the adjustment plate 6, so as to cut the paper jam.

[0039] After the cutting is completed, as the conveyor belt 20 moves to the right, the motor three 23 is started, and the bidirectional threaded rod 24 rotates under the drive of the motor three 23. At this time, the bidirectional threaded rod 24 will drive the sliding ring 25 to move during the rotation, and the sliding ring 25 will drive the correction plate 13 to move during the movement. At this time, the correction plate 13 will correct the paper jam during the movement. When the paper jam is offset, it will first contact the baffle 17. At this time, the baffle 17 is squeezed inward to squeeze the connecting plate 16, so that the spring 14 is compressed inside the correction plate 13. Due to the elastic characteristics of the spring 14, the correction effect can be maintained for a long time. At the same time, the limit plate 15 can limit the spring 14 to prevent it from drastic deformation and falling off, and then the paper jam falls into the collection box.
