Abstract
Description
Technical Field
[0001] This utility model relates to the field of carding machine technology, specifically to a device for adjusting the tension of the tensioner belt of a carding machine. Background Technology
[0002] A carding machine is mainly used to comb and process fibrous materials such as cotton, wool, and synthetic fibers, turning them into uniform, soft, and smooth fiber bundles for subsequent spinning and weaving processes. It improves cotton utilization and the quality of textiles, playing a vital role in the textile industry. The working principle of a carding machine is to use a series of carding components to comb, open, mix, and remove impurities from the fiber material, creating uniform fiber bundles.
[0003] In some existing carding machines, the bearing clearance of the tensioning wheel of the small pressure roller in the faucet coiler drive is too small, and the tension of the flat belt is too large, resulting in a short service life of the tensioning wheel and damage to it. If the belt tension is too small, it is easy to slip and run off-track, making it unusable. In addition, currently, when using carding machines, operators cannot adjust the tension of the cotton thread in time. However, the improper tension will affect the carding effect of the carding machine on the cotton fibers. If the tension is too loose, the cotton fibers will not be combed sufficiently, and cotton knots and impurities will easily remain. If the tension is too tight, it may damage the cotton fibers, causing the fibers to break and form new cotton knots. Utility Model Content

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0025] Please see Figure 1-6 As shown, a tension adjustment device for the tensioner belt of a carding machine includes a first mounting plate 1 and a second mounting plate 2. Two rotating rollers, a first rotating roller 3 and a second rotating roller 4, for conveying cotton thread are disposed between the first mounting plate 1 and the second mounting plate 2. The first mounting plate 1 and the second mounting plate 2 work together to support the first rotating roller 3 and the second rotating roller 4. The first mounting plate 1 and the second mounting plate 2 are mounted on the carding machine. The coordinated use of the first rotating roller 3 and the second rotating roller 4 allows for stable conveying of the processed cotton thread. The device also includes:
[0026] Limiting rings 5 are fixed at both ends of the first rotating roller 3 and the second rotating roller 4 to prevent the cotton thread from slipping off the rollers. By setting limiting rings 5 at both ends of the first rotating roller 3 and the second rotating roller 4, the cotton thread can be prevented from slipping off the first rotating roller 3 and the second rotating roller 4 during conveying. A rotating shaft 6 is fixed at both ends of the first rotating roller 3 and the second rotating roller 4. The rotating shaft 6 can connect the first rotating roller 3 and the second rotating roller 4 and support their rotation. A pressure roller 7 is set between the first rotating roller 3 and the second rotating roller 4 to adjust the tension of the cotton thread. By setting the pressure roller 7, the cotton thread conveyed on the first rotating roller 3 and the second rotating roller 4 can be pressed to adjust the tension of the cotton thread.
[0027] Five bearings 8 are installed inside the first mounting plate 1 and the second mounting plate 2 to improve rotational stability. Three bearings 8 are installed inside the first mounting plate 1, and two bearings 8 are installed inside the second mounting plate 2. Installing bearings 8 inside the first mounting plate 1 and the second mounting plate 2 facilitates the rotation of the shafts 6 at both ends of the first rotating roller 3 and the second rotating roller 4 within the bearings 8, improving the rotational stability of the shafts 6, and thus improving the rotational stability of the first rotating roller 3 and the second rotating roller 4. Each bearing 8 includes an inner ring 81 located outside the shaft 6, an outer ring 82 located outside the inner ring 81, and a plurality of balls 83 disposed between the inner ring 81 and the outer ring 82. A cage 84 is fitted around the outer side of each ball 83. The inner ring 81 and the outer ring 82 work together to facilitate the rolling of several balls 83 between the inner ring 81 and the outer ring 82. Since the outer ring 82 is fixed in the first mounting plate 1 and the second mounting plate 2, the inner ring 81 can rotate in the outer ring 82 by the rolling of several balls 83 when it rotates. By setting the retainer 84, the several balls 83 can be divided and limited at equal distances to prevent the several balls 83 from contacting each other. One side of the inner ring 81 of the three bearings 8 in the first mounting plate 1 is fixed with a connecting shaft 85. The connecting shaft 85 is rotatably connected to the inner wall of the first mounting plate 1. Three bearings 8 are installed in the first mounting plate 1, two of which correspond to the two bearings 8 installed in the second mounting plate 2, and are used to support the rotation of the first rotating roller 3 and the second rotating roller 4.
[0028] A drive mechanism 9 is provided on the outer side of the first mounting plate 1 to drive the first rotating roller 3 and the second rotating roller 4 to rotate. The drive mechanism 9 provides power to drive the first rotating roller 3 and the second rotating roller 4 to rotate, thereby conveying cotton thread. The drive mechanism 9 includes a support frame 91 fixed to one side of the first mounting plate 1. The support frame 91 supports and mounts a motor 92, which is detachable. The motor 92 is mounted on the inner side of the support frame 91. The output end of the motor 92 is mounted to one end of a connecting shaft 85 via a coupling. A drive pulley 93 is fixed to the end of the connecting shaft 85 away from the motor 92. The motor 92 is connected to the middle part of the three bearings 8 inside the first mounting plate 1 via a coupling. The bearing 8 is connected to the connecting shaft 85, so that while the motor 92 drives the connecting shaft 85 to rotate, the connecting shaft 85 can also rotate within the bearing 8, improving the stability of the motor 92 drive. The outer side of the drive pulley 93 is connected to two mirror-mounted drive belts 94, and the inner side of each of the two drive belts 94 is connected to a driven pulley 95. The driven pulley 95 is fixed to one end of the connecting shaft 85. By setting the drive pulley 93, the two mirror-mounted drive belts 94 can be driven to rotate simultaneously. The rotation of the two drive belts 94 can drive the two driven pulleys 95 to rotate simultaneously, so that the first rotating roller 3 and the second rotating roller 4 connected by the two bearings 8 rotate synchronously.
[0029] Both the first mounting plate 1 and the second mounting plate 2 are equipped with an adjustment mechanism 10 for moving the pressure roller 7. The adjustment mechanism 10 allows for adjustment of the height of the pressure roller 7, thereby adjusting the tension of the cotton thread conveyed on the first rotating roller 3 and the second rotating roller 4, improving the ease of operation for workers. The adjustment mechanism 10 includes a slot 101 formed inside the second mounting plate 2. A movable plate 102 is installed inside the slot 101, facilitating the vertical movement of the movable plate 102 within the slot. The inner diameter of the slot 101 is the same as the size of the movable plate 102. The inner wall of the movable plate 102 is threaded with an adjusting rod 103. A turntable 104 is fixed to the top of the adjusting rod 103, and the top of the adjusting rod 103 is rotatably connected to the inner wall of the slot 101. The adjusting rod 103 in the first mounting plate 1 is unthreaded, while the adjusting rod 103 in the second mounting plate 2 has an externally threaded screw. The operator rotates the threaded adjusting rod 103 in the second mounting plate 2 via the turntable 104. Because the threaded adjusting rod 103 in the second mounting plate 2 is threadedly connected to the movable plate 102, when the threaded adjusting rod 103 in the second mounting plate 2 rotates, the movable plate 102... The plate 102 moves up and down as the threaded adjusting rod 103 rotates. A groove 105 is formed on the inner wall of the slot 101, and a slider 106 is slidably connected to the inner wall of the groove 105. The slider 106 is fixed to the outer side of the moving plate 102. By fixing the slider 106 to the outer side of the moving plate 102 and forming a groove 105 in the slot 101 that matches the slider 106, the moving plate 102 can move while simultaneously causing the slider 106 to slide within the groove 105. This limits the movement of the moving plate 102, preventing it from rotating along with the adjusting rod 103. To improve the stability of the moving plate 102, a connecting rod 107 is fixed on one side of the moving plate 102, and a base 108 is fixed at one end of the connecting rod 107. The base 108 is rotatably connected to one end of the pressure roller 7. By setting the connecting rod 107, the base 108 can be connected to the moving plate 102. When the moving plate 102 moves, it can drive the base 108 to move as well. Since the pressure roller 7 is installed in two symmetrical bases 108, the base 108 can drive the pressure roller 7 to move while it moves, thereby adjusting the tension of the cotton thread conveyed on the first rotating roller 3 and the second rotating roller 4.
[0030] Working principle: When the operator uses the carding machine to process and convey cotton thread, the cotton thread is conveyed by the cooperation of the first rotating roller 3 and the second rotating roller 4 inside the carding machine. During conveying, the rotation of the first rotating roller 3 and the second rotating roller 4 is made more stable by the cooperation of the drive mechanism 9 and the five bearings 8 in the first mounting plate 1 and the second mounting plate 2. At the same time, the operator can adjust the height of the pressure roller 7 through the adjustment mechanism 10. Moving the pressure roller 7 can adjust the tension of the cotton thread conveyed on the first rotating roller 3 and the second rotating roller 4, improving the operator's ease of operation.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
