Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, and in particular to a paper product winding tension adjustment device. Background Technology

[0002] In paper product winding equipment, tension control is one of the key factors in ensuring winding quality. Improper tension control can easily lead to problems such as paper wrinkling, loosening, and tearing, affecting product quality and production efficiency. Traditional tension adjustment devices typically use upper and lower rollers with fixed spacing to apply pressure, thereby controlling the tension during paper transport.

[0003] However, this structure struggles to achieve precise pressure adjustment when dealing with paper of varying thicknesses. When the paper is thick, the fixed-gap roller structure may apply excessive pressure, causing damage and deformation to the paper edges, and even affecting the tightness of subsequent winding. Conversely, when the paper is thin, insufficient pressure may cause the paper to slip or lack tension, leading to quality issues such as wrinkles and misalignment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a paper product winding tension adjustment device, which aims to improve the problem that rollers with fixed spacing have difficulty maintaining tension stability when dealing with paper of different thicknesses, thus affecting the versatility of the equipment.

[0008] Preferably, a second motor is fixedly connected to the outer wall of the frame, and a positive and negative lead screw is fixedly provided at the output end of the second motor.

[0009] Preferably, the outer wall of the positive and negative lead screw is threaded with a sliding plate, and the outer wall of the sliding plate is slidably connected with a limit post.

[0010] Preferably, both ends of the limiting post are fixedly connected to the inner wall of the frame, and a spring is fixedly connected to the inner wall of the sliding plate.

[0011] Preferably, a limiting ring is fixedly connected to the outer wall of the second spring, and the outer wall of the limiting ring is slidably connected to the inner wall of the sliding plate.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a paper product winding tension adjustment device, including a frame 1, a bearing 2 fixedly connected to the inner wall of the frame 1, a fixed cylinder 3 provided inside the bearing 2, a rotating screw 4 rotatably connected to the inner wall of the frame 1, a knob 5 fixedly connected to the outer wall of the rotating screw 4, a sliding block 6 threadedly connected to the outer wall of the rotating screw 4, the outer wall of the sliding block 6 slidably connected to the inner wall of the frame 1, a sliding block 7 provided on the upper surface of the sliding block 6, a spring 8 fixedly connected to the upper surface of the sliding block 7, a support frame 9 fixedly connected to the top of the spring 8, a force-applying cylinder 10 rotatably connected inside the support frame 9, and a winding assembly provided on the outer wall of the frame 1.

[0025] Specifically, frame 1 supports bearing 2, which in turn supports fixed cylinder 3. Frame 1 also supports rotating lead screw 4, ensuring its stable rotation. Simultaneously, rotating lead screw 4 provides fixed support for knob 5. When knob 5 rotates, it drives rotating lead screw 4 to rotate synchronously. The rotation of lead screw 4 causes sliding block 6 to slide, and the sliding of sliding block 6 also pushes sliding block 7 upwards. This will also cause spring 8 to move upward, which in turn will cause support frame 9 and force cylinder 10 to move upward synchronously. The sliding of support frame 9 allows it to adjust the distance between fixed cylinder 3 and force cylinder 10 according to the thickness of paper 13, ensuring that different thicknesses of paper 13 will not directly affect the tension, avoiding being pressed too tightly due to being too thick or too loosely due to being too thin. The elasticity of spring 8 allows force cylinder 10 to provide continuous flexible pressing force on paper 13, keeping the contact pressure between force cylinder 10 and paper 13 constant, maintaining stable tension, and improving the versatility of the equipment.

[0026] Reference Figure 3 The winding assembly includes a motor 11, the outer wall of which is fixedly connected to the outer wall of the frame 1. A winding drum 12 is fixedly provided at the output end of the motor 11. Paper 13 is provided on the outer wall of the winding drum 12. The outer walls of the paper 13 are all provided on the outer walls of the fixed drum 3 and the force-applying drum 10.

[0027] Specifically, frame 1 can provide fixed support for motor 11. When motor 11 is turned on, motor 11 will drive take-up drum 12 to rotate, and the rotation of take-up drum 12 will wind up paper 13. The tension of paper 13 during winding can be adjusted by fixing drum 3 and force application drum 10.

[0028] Reference Figure 4 A motor 14 is fixedly connected to the outer wall of frame 1. A positive and negative lead screw 15 is fixedly installed at the output end of motor 14. A sliding plate 16 is threadedly connected to the outer wall of the positive and negative lead screw 15. A limit post 17 is slidably connected to the outer wall of the sliding plate 16.

[0029] Specifically, frame 1 can provide fixed support for motor 2 14. When motor 2 14 is turned on, motor 2 14 will drive the positive and negative lead screws 15 to rotate. The rotation of the positive and negative lead screws 15 will drive the sliding plates 16 on both sides to slide synchronously against each other on the outer wall of the limiting post 17. The limiting post 17 can provide support for the sliding plates 16 to ensure the stability of the sliding plates 16.

[0030] Reference Figure 4 Both ends of the limiting post 17 are fixedly connected to the inner wall of the frame 1. The inner wall of the sliding plate 16 is fixedly connected to the second spring 18. The outer wall of the second spring 18 is fixedly connected to the limiting ring 19, and the outer wall of the limiting ring 19 is slidably connected to the inner wall of the sliding plate 16. The outer wall of the limiting ring 19 is fixedly connected to the connecting post 20, and the outer wall of the connecting post 20 is slidably connected to the inner wall of the sliding plate 16. The outer wall of the connecting post 20 is fixedly connected to the limiting plate 21, and the outer wall of the limiting plate 21 is set on the outer wall of the paper 13.

[0031] Specifically, the frame 1 can provide fixed support for the limiting post 17, while the sliding plate 16 can provide fixed support for the second spring 18. The second spring 18 can also push the limiting ring 19 to slide, thereby driving the connecting post 20 and the limiting plate 21 to slide. By adjusting the spacing of the limiting plates 21 on both sides according to the width of the paper 13, the paper 13 can be limited to prevent lateral displacement and ensure that the winding always maintains the axis alignment. At the same time, the second spring 18 allows the limiting plate 21 to slide elastically, avoiding hard contact between the limiting plate 21 and the paper 13, and preventing the limiting plate 21 from being set too tight, which would damage the edge of the paper 13. The second spring 18 allows the limiting plate 21 to always be close to the edge without being overly compressed.

[0032] Working principle: When using this device, first turn knob 5, which drives the lead screw 4 to rotate. The rotation of lead screw 4 causes slider 6 to slide, and the sliding of slider 6 also causes slider 7 to slide upward. Simultaneously, the sliding of slider 7 causes spring 8 to slide upward, thereby causing the support frame 9 to slide, which in turn causes the force application cylinder 10 to slide. Adjust the distance between the force application cylinder 10 and the fixed cylinder 3 according to the thickness of the paper 13. Then turn on motor 14, which drives the forward and reverse lead screws 15 to rotate. The rotation of the forward and reverse lead screws 15, in turn, causes the spring 8 to slide upward, thereby causing the support frame 9 to slide, which in turn causes the force application cylinder 10 to slide. The sliding plate 16 slides on the outer wall of the limiting post 17. The distance between the two sliding plates 16 is adjusted according to the width of the paper 13 so that the limiting plate 21 contacts the paper 13 and limits the paper 13. That is, this device can not only ensure that the different thicknesses of the paper 13 will not directly affect the tension by adjusting the distance between the force application cylinder 10 and the fixed cylinder 3, avoiding being pressed too tightly because it is too thick or too loose because it is too thin, thus maintaining the stability of the tension and improving the versatility of the equipment, but also use the spring 28 to drive the limiting plate 21 to elastically limit the paper 13, preventing the paper roll from shifting laterally, avoiding damage to the edge of the paper roll, and improving the neatness of the winding.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
