Description

Technical Field

[0001] This utility model relates to the field of cotton yarn tension adjustment technology, specifically a cotton yarn tension adjustment device. Background Technology

[0002] Cotton yarn, a basic textile raw material made from cotton fiber through spinning, is widely used in clothing, home textiles, and industrial fabrics after being plied. Based on the differences in spinning processes, it can be further divided into carded yarn and combed yarn. The former has a shorter process flow and lower cost, and is often used to make coarse cloth and packaging cloth with low quality requirements. The latter removes short fibers and impurities through the combing process, resulting in high fiber parallelism, straightness, and evenness. It is mostly used in high-end clothing fabrics and fine home textile products. In order to improve the quality of cotton yarn products, tension adjustment is often required during the textile processing.

[0003] Chinese Patent Publication No. CN214421999U discloses a stable cotton yarn spinning tension adjustment device, including a base. A first support plate is connected to the top left of the base, and a first guide wheel is rotatably connected to the side of the first support plate. A second support plate is connected to the top right of the base, and a second guide wheel is rotatably connected to the side of the second support plate. A mounting frame is provided between the first and second support plates, and the mounting frame is connected to the front and rear sides of the base. This invention uses a worm gear to move the first connecting plate to the top of the adjusting roller, rotate the second connecting plate to the bottom of the adjusting roller, and then rotate the worm gear. The worm gear drives the worm wheel to rotate, which in turn drives the rotating frame to rotate. The rotating frame drives the fixing block to move into the fixing groove to fix the second connecting plate and limit the cotton yarn to prevent the cotton yarn from shifting during tension adjustment.

[0004] However, the present invention has the following problems in actual use;

[0005] When yarn accidentally gets tangled on the guide roller or tension adjustment component, the motion resistance will rise rapidly in a very short time, causing the tension to exceed the material's tolerance limit. Since the equipment lacks an automatic energy release or power cutting device, it cannot eliminate stress concentration in time, which can easily cause material breakage. Moreover, strong pulling can easily cause the tension roller bearing to deform, seriously affecting the transmission accuracy and equipment life. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a cotton yarn tension regulating device, which has the following beneficial effects:

[0019] This cotton yarn tension regulating device, through the coordinated arrangement of a hydraulic damping rod, a tension rod, and a load-bearing plate, allows the hydraulic damping rod to absorb the instantaneous impact force and slow down the displacement speed of the tension rod when the yarn becomes entangled and causes a sudden increase in tension. This not only prevents the tension from exceeding the material's bearing capacity in a short time and thus prevents yarn breakage, but also forms a protective barrier during energy dissipation, significantly reducing the tensile load on the internal parts of the equipment. By suppressing the direct action of abnormal external forces on the structural components, it significantly reduces the risk of deformation of components such as the tension rod, avoiding problems such as decreased tension regulation accuracy and shortened equipment life caused by mechanical structural damage. Simultaneously, the load-bearing plate provides support for the hydraulic damping rod. A stable support base ensures the stability of the hydraulic damping rod during operation and effectively disperses the instantaneous impact load borne by the hydraulic damping rod. Through a rigid connection with the base, part of the impact force is evenly transmitted to the base. Through the coordinated setup of the drive motor, controller, and tension rod, the tension of the cotton yarn is adjusted in real time by changing the angle of the tension rod using the driving force generated by the drive motor, thus achieving dynamic tension adjustment. During this process, the hydraulic damping rod at the lower end of the tension rod simultaneously plays a supporting and buffering role. It rises and falls slowly with the rotation of the tension rod, suppressing the swaying of the tension rod through hydraulic damping force and maintaining its balance during rotation with stable supporting reaction force, ensuring stability during the adjustment process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example 1;

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: a cotton yarn tension regulating device, which is mainly used in cotton yarn spinning. It includes a base 1 and a controller 2. A display screen 9 is provided on one side of the controller 2. A control button 10 is provided on the outer surface of the controller 2 near the display screen 9. A heat dissipation groove 11 is provided on the outer surface of the controller 2 away from the display screen 9. A filter screen 12 is provided on the inner wall of the heat dissipation groove 11. A tension rod 3 is provided on the inner wall of the base 1. A rotating shaft 7 is rotatably connected to the side of one end of the tension rod 3. Multiple tension regulating wheels 8 are evenly arranged on the outer surface of the rotating shaft 7. The multiple tension regulating wheels 8... The output ends are all connected to the input wires of the controller 2. The inner side wall of the base 1 is provided with a wire guide wheel 13. The inner side wall of the base 1 is provided with a guide wheel 14 near the wire guide wheel 13. The inner side wall of the base 1 is provided with a driven wheel 15 near the guide wheel 14. There are two tension rods 3. The two tension rods 3 are symmetrically arranged with the center line of the width direction of the base 1 as the axis of symmetry. The lower ends of the two tension rods 3 are detachably connected to a hydraulic damping rod 4. The lower end of the hydraulic damping rod 4 is provided with a load-bearing plate 5. One end of the load-bearing plate 5 is fixedly connected to the side of the base 1 near the tension rod 3. The outer surface of the base 1 is provided with a drive motor 6 near the controller 2.

[0028] The above technical solution first guides the yarn into the device via the guide roller 13, standardizing the initial path. Then, the yarn passes through the driven roller 15, which assists in yarn transmission, sharing some of the yarn tension and reducing pressure on adjustment components such as the tension lever 3. Simultaneously, when passing the guide roller 14, the yarn path is limited, ensuring it accurately bypasses the tension adjusting roller 8. The tension adjusting roller 8 directly contacts the yarn, and its internal pressure sensor monitors tension data in real time, transmitting it to the controller 2. The controller 2 compares this data with preset data in real time. When the tension is lower than the preset value, the controller 2 outputs a command to control the drive motor. The machine 6 rotates, thereby changing the angle of the tension rod 3 and the tension adjusting wheel 8 to achieve dynamic adjustment of the yarn tension. At the same time, the display screen 9 on the side of the controller 2 can display the current tension value, set parameters, equipment status and fault prompts in real time. The operator can manually adjust the target tension, start and stop the equipment, and switch working modes using the control button 10. When the controller 2 is running, the heat dissipation groove 11 on its side can dissipate the heat inside the controller 2 to prevent the electronic components inside the controller 2 from overheating and being damaged. The filter screen 12 inside the heat dissipation groove 11 can block dust, fibers and other debris from entering the interior of the controller 2 and extend the service life of the controller 2.

[0029] Example 2;

[0030] Please see Figure 2 and Figure 4 This utility model provides a technical solution based on Embodiment 1. The output end of the drive motor 6 is threaded through one side of the base 1 and connected to the inner wall of the tension rod 3. The input end of the drive motor 6 is connected to the output end of the controller 2. Multiple buffer components 16 are provided on both sides of the base 1. The multiple buffer components 16 are symmetrically arranged with the center line of the length direction of the base 1 as the axis of symmetry. The buffer component 16 includes a fixing frame 1601 and a connecting plate 1604. One side of the fixing frame 1601 is fixedly connected to one side of the base 1. A damping rod 1602 is snapped into the inner wall of the fixing frame 1601. A return spring 1603 is sleeved on the outer surface of the damping rod 1602. One end of the damping rod 1602 is threaded through one side of the fixing frame 1601 and connected to the inside of the connecting plate 1604. A fastening bolt 1605 is detachably connected to the upper end of the connecting plate 1604.

[0031] With the above technical solution, after the equipment is installed on the ground, if the yarn accidentally gets tangled inside the equipment, the impact force generated by the motion resistance is transmitted to the base 1. The damping rod 1602 and the return spring 1603 in the buffer assembly 16 absorb the impact force. At the same time, when the damping rod 1602 absorbs the impact, the return spring 1603 is compressed and stores elastic potential energy. After the impact, the return spring 1603 releases energy to push the damping rod 1602 to return to its original position, ensuring that the buffer assembly 16 can work repeatedly and avoiding performance degradation due to long-term pressure. With the setting of the fixing frame 1601, it can act as an intermediate carrier for force transmission, transmitting part of the force to the damping rod 1602 and also dispersing part of the impact force to the ground, preventing excessive local force concentration. At the same time, with the setting of the connecting plate 1604 and the fastening bolt 1605, one end of the buffer assembly 16 can be fixed to the external ground to achieve a rigid connection, ensuring the effective transmission of impact energy.

[0032] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power via standard interfaces. The main controller can be any commercially available known device. There are no special restrictions on the specific models of the electrical components; any commercially available ordinary products can be selected, as long as they meet the usage requirements of this utility model.

[0033] In this invention, the working steps of the device are as follows:

[0034] First, the device power is turned on, and controller 2 starts a self-test program to check the working status of drive motor 6, tension adjusting wheel 8 sensor, and hydraulic damping rod 4. The operator sets the target tension value through control button 10. The yarn is drawn out from the external package and passes sequentially around thread guide wheel 13, driven wheel 15, guide wheel 14, and finally around the surface of tension adjusting wheel 8. The pressure sensor inside tension adjusting wheel 8 monitors the yarn tension in real time and converts the mechanical pressure into an electrical signal, which is transmitted to controller 2 via cable. Controller 2 compares the real-time tension data with the preset value. If the tension is lower than the preset value, controller 2 starts drive motor 6 to rotate forward. Drive motor 6 drives tension rod 3 to rotate, causing tension adjusting wheel 8 to lift synchronously. The tension bar 3 is raised to increase the tension of the yarn. When the tension bar 3 rotates, the hydraulic damping rod 4 supports it to ensure the stability of the tension bar 3. At the same time, the controller 2 compares the tension data with the preset value. If the tension is higher than the preset value, the controller 2 controls the drive motor 6 to reverse, so that the tension bar 3 drives the tension adjusting wheel 8 to descend, thereby reducing the tension of the yarn. When the yarn accidentally gets tangled in the equipment, causing a sudden increase in tension, the hydraulic damping rod 4 absorbs the instantaneous impact force through hydraulic oil damping, slows down the displacement of the tension bar 3, and prevents the yarn from breaking. At the same time, when part of the impact force is transmitted to the base 1, the damping rod 1602 and the return spring 1603 inside the side buffer assembly 16 absorb the impact force to ensure the stability of the base 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
