Description

Technical Field

[0001] This utility model relates to the field of cotton processing technology, and in particular to a tension structure for opening cotton raw materials. Background Technology

[0002] Before transportation, loose cotton needs to be compressed into compact bales to facilitate long-distance transport and reduce storage space. During use, a cotton opener is used to loosen the raw cotton. During this process, high-speed rotating components (such as beaters) pull the cotton raw material, breaking large clumps of cotton into smaller fiber bundles. Because cotton fibers have a certain degree of stickiness and adhesion, a large amount of fiber remains on the surface, in gaps, and in corners of the pulling structure during prolonged pulling operations. If these residual fibers are not cleaned in time, they will gradually accumulate and form a thick fiber layer. This not only blocks the normal operating channels of the pulling structure, reducing the pulling force and resulting in poor opening effect, preventing the cotton from being fully loosened, but may also cause subsequent cotton raw materials to become entangled with these residual fibers, further affecting the quality and efficiency of opening. Inevitably, the cotton raw material will contain various impurities, such as dust, cottonseed hulls, and short fibers. During the pulling process, some of these impurities can easily get stuck in the teeth, hooks, or other parts of the pulling structure. Over time, impurities accumulate, increasing the operational burden on equipment, reducing its performance, and potentially causing wear and damage to the tensioning structure. From a hygiene and product quality perspective, tensioning structures that are not cleaned regularly are prone to harboring bacteria, mold, and other microorganisms. These microorganisms can contaminate raw cotton materials, affecting the hygiene standards and quality safety of the final cotton product. This is especially true when producing cotton products for medical and hygiene applications, where even higher cleanliness requirements are necessary.

[0003] In the existing technology, the tension structure is not easy to disassemble and replace after installation. When the tension structure is used for a long time, a lot of impurities accumulate inside, which will reduce the efficiency of cotton opening and may damage the equipment due to excessive impurities, thus reducing work efficiency and increasing production costs.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0025] Reference Figure 1-6 A tensioning structure for opening cotton raw materials includes a base 1, a fixed mounting plate 2 fixedly connected to the upper surface of the base 1, a symmetrically distributed rotating shaft 3 mounted on the inner wall of the fixed mounting plate 2 via bearings, a rotating mounting seat 4 fixedly connected to one end of the rotating shaft 3, a square mounting hole 5 opened on one side surface of the rotating mounting seat 4, a limiting groove 6 opened on the inner top wall of the square mounting hole 5, a first spring 7 fixedly connected to the inner top wall of the limiting groove 6, a pressure plate 8 fixedly connected to one end of the first spring 7, and the outer surface of the pressure plate 8 slidingly sleeved with the inner wall of the limiting groove 6.

[0026] A connecting rod 9 is fixedly connected to the upper surface of the pressure plate 8. One end of the connecting rod 9 passes through and extends to the outer surface of the rotating mounting base 4. A circular pressing block 10 is fixedly connected to one end of the connecting rod 9. Pressing the circular pressing block 10 causes the pressure plate 8 to move downward through the connecting rod 9. The movement of the pressure plate 8 causes the limiting block 14 to move downward until the outer surface of the limiting block 14 is no longer inserted into the inner wall of the limiting groove 6, thus releasing the limiting effect.

[0027] Furthermore, a first square block 11 is movably inserted into the inner wall of the square mounting hole 5, and a square hole 12 is opened on the upper surface of the first square block 11. A second spring 13 is fixedly connected to the inner bottom wall of the square hole 12.

[0028] Furthermore, one end of the second spring 13 is fixedly connected to a limiting block 14. The outer surface of the limiting block 14 is slidably sleeved with the inner wall of the square hole 12. One end of the limiting block 14 is provided with a bevel 15. The bevel 15 allows the first square block 11 to be smoothly and quickly inserted into the square mounting hole 5.

[0029] Furthermore, one end of the limiting block 14 is movably inserted into the inner wall of the limiting groove 6. A pulling roller 16 is fixedly connected to one side surface of the first square block 11, and a second square block 17 is fixedly connected to one side surface of the pulling roller 16. A trapezoidal slide groove 18 is symmetrically distributed on the upper surface of the base 1. A trapezoidal slider 19 is slidably sleeved on the inner wall of the trapezoidal slide groove 18. The trapezoidal slide groove 18 and the trapezoidal slider 19 cooperate with each other to limit the movement of the movable mounting plate 20.

[0030] Furthermore, a movable mounting plate 20 is fixedly connected to the upper surface of each of the two trapezoidal sliders 19, a fixing block 21 is fixedly connected to the upper surface of the base 1, an electric telescopic rod 22 is fixedly connected to one side surface of the fixing block 21, and one end of the electric telescopic rod 22 is fixedly connected to one side surface of the movable mounting plate 20. With the cooperation of the trapezoidal slide groove 18 and the trapezoidal sliders 19, the electric telescopic rod 22 drives the movable mounting plate 20 to move.

[0031] Furthermore, a rotating disk 23 is mounted on the inner wall of the movable mounting plate 20 via a bearing. The inner wall of the rotating disk 23 is movably inserted into the outer surface of the second square block 17, and a gear 24 is fixedly sleeved on the outer surface of one end of the rotating shaft 3.

[0032] Furthermore, the teeth of the two gears 24 mesh with each other, and a servo motor 25 is fixedly mounted on the upper surface of the base 1 via a heightening seat. The output shaft of the servo motor 25 is fixedly connected to one end of one of the rotating shafts 3 via a coupling. A discharge port 26 is opened on the upper surface of the base 1, and support legs 27 arranged in a rectangular array are fixedly connected to the lower surface of the base 1. Side plates 28 arranged symmetrically are fixedly connected to the upper surface of the base 1.

[0033] By rotating the mounting base and moving the mounting plate, the tension roller can be quickly and easily disassembled and installed, and the tension roller can be efficiently cleaned or replaced, thereby effectively preventing problems such as reduced cotton opening efficiency and equipment damage.

[0034] Working principle: Step 1, when the pulling roller 16 is in normal use, start the servo motor 25. The servo motor 25 drives one of the rotating shafts 3 to rotate. One of the rotating shafts 3 drives one of the pulling rollers 16 to rotate through one of the rotating mounting seats 4. At the same time, the rotation of one of the shafts drives one of the gears 24 to rotate. The rotation of one of the gears 24 drives another rotating shaft 3 to rotate through another meshing gear 24. The other rotating shaft 3 drives another pulling roller 16 to rotate through another rotating mounting seat 4. Then, the compressed cotton raw material is fed into the device. The two rollers cooperate to loosen the cotton raw material.

[0035] Step 2: When the tension roller 16 has been used for a long time and has accumulated a lot of impurities, it needs to be cleaned or replaced. Start the electric telescopic rod 22. With the cooperation of the trapezoidal slide groove 18 and the trapezoidal slider 19, the moving mounting plate 20 moves. The outer surface of the second square block 17 disengages from the inner wall of the rotating disk 23. Press the circular pressing block 10. The connecting rod 9 drives the pressure plate 8 to move downward. The movement of the pressure plate 8 drives the limiting block 14 to move downward until the outer surface of the limiting block 14 is no longer inserted into the inner wall of the limiting groove 6. At this time, the rotating mounting seat 4 no longer limits the first square block 11. The tension roller 16 can then be removed for cleaning or replacement.

[0036] Step 3: After the pulling roller 16 is cleaned or replaced, move the pulling roller 16 along the square mounting hole 5. The upper end of the limiting block 14 is provided with an inclined surface 15. During the movement, the rotating mounting base 4 applies a downward force to the inclined surface 15, thereby causing the limiting block 14 to move. The second spring 13 is compressed until the first square block 11 is completely moved into the square mounting hole 5. At this time, the upper surface of the square mounting hole 5 no longer applies a downward force to the limiting block 14, and the second spring 13 returns to its original position. The force of the spring causes the outer surface of the limiting block 14 to movably engage with the inner wall of the limiting groove 6, thus limiting the pulling roller 16. Start the electric telescopic rod 22. With the cooperation of the trapezoidal slide groove 18 and the trapezoidal slider 19, move the mounting block toward the pulling roller 16 until the outer surface of the second square block 17 contacts the inner wall of the rotating disk 23. At this time, the installation of the pulling roller 16 is completed, and the equipment can work normally.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
