Description

Technical Field

[0001] This utility model relates to the field of tension detection technology in spinning processing, specifically a precision yarn tension detection device for pure cotton yarn production. Background Technology

[0002] Yarn is a textile product made from various textile fibers processed to a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery, and is divided into staple fiber yarn and continuous filament yarn. Yarn fineness is expressed in various ways, such as count, metric count, English count, denier, etc. (see count). Yarn twist is expressed as the number of twists per meter or inch. Wool yarn and woolen thread are generally used to weave sweaters, trousers, vests, scarves, hats, gloves, and to knit various spring and autumn clothing items, serving both a warm and decorative purpose.

[0003] Existing yarn tension testing devices cannot perform comparative operations on yarn tension and cannot accurately measure the yarn tension value; therefore, a precision yarn tension testing device for pure cotton yarn production is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a precision yarn tension detection device for pure cotton yarn production, which makes it easy to accurately determine the yarn tension value and make the detection data more accurate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision yarn tension detection device for pure cotton yarn production, comprising a mounting base, a telescopic device disposed on the mounting base, a slide block, at least two tension sensors, and at least two clamping mechanisms for clamping and fixing the yarn; the telescopic device is disposed on one side of the top of the mounting base; and the output end of the telescopic device is disposed on the slide block, the slide block being slidably disposed with the mounting base; at least two tension sensors are disposed on the side of the slide block away from the telescopic device, and a hanging ring is provided on the side of the tension sensor away from the slide block; the top of the slide block is provided with a display electrically connected to the tension sensor; the at least two clamping mechanisms have the same structure and function, and the number of clamping mechanisms and tension sensors are the same and correspond one-to-one; the clamping mechanism is disposed on the side of the top of the mounting base away from the telescopic device.

[0006] To facilitate the selection of the telescopic device, the preferred telescopic device for a precision yarn tension detection device used in the production of pure cotton yarn according to this utility model is an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod.

[0007] To facilitate yarn clamping and fixing, as a preferred embodiment of the precision yarn tension detection device for pure cotton yarn production according to this utility model, the clamping mechanism includes a clamping frame vertically arranged on the top of the mounting base in the form of a frame structure, a lower clamping plate arranged at the bottom inside the clamping frame, and an upper clamping plate arranged above the lower clamping plate. The upper clamping plate is slidably connected to the clamping frame, and a threaded rod with a handle at one end is provided on the clamping frame. One end of the threaded rod is threaded through the clamping frame and rotatably connected to the upper clamping plate.

[0008] To facilitate the restriction of the upper clamping plate, in a preferred embodiment of this utility model for a precision yarn tension detection device used in the production of pure cotton yarn, the clamping frame has symmetrical grooves on both sides along the height direction, and a slider fixedly connected to the upper clamping plate is slidably arranged in the groove.

[0009] To improve the stability of yarn fixation, as a preferred embodiment of the precision yarn tension detection device for pure cotton yarn production according to this utility model, the lower clamping plate and the upper clamping plate are provided with wavy ridges on opposite sides.

[0010] To improve the stability of the slide movement, as a preferred embodiment of the precision yarn tension detection device for pure cotton yarn production according to this utility model, the top of the mounting base is provided with a limiting groove along the length direction, and a limiting block that is fixedly connected to the bottom of the slide is slidably provided in the limiting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes at least two clamping mechanisms and at least two tension sensors. Two short sections of yarn are cut from the same yarn, and each section is passed through two hanging loops. The ends of the yarn are clamped and fixed by the clamping mechanisms. When no tension is applied, the two tension sensors display the same tension value. By activating the telescopic device, the slide moves the two tension sensors, pulling the yarn away from the clamping mechanisms, further facilitating the detection of yarn tension. Furthermore, by selecting the same yarn, applying the same tension, and performing simultaneous testing, the displayed values ​​can be compared and referenced, making it easier to accurately determine the yarn tension and resulting in more accurate data.

[0019] Please see Figures 1 to 5 A precision yarn tension detection device for pure cotton yarn production includes a mounting base 1, a telescopic device 2 disposed on the mounting base 1, a slide block 3, at least two tension sensors 4, and at least two clamping mechanisms 5 for clamping and fixing the yarn. The telescopic device 2 is disposed on one side of the top of the mounting base 1, and the output end of the telescopic device 2 is disposed on the slide block 3, which is slidably disposed with the mounting base 1. At least two tension sensors 4 are disposed on the side of the slide block 3 away from the telescopic device 2, and a hanging ring 6 is provided on the side of the tension sensor 4 away from the slide block 3. A display 7 electrically connected to the tension sensor 4 is provided on the top of the slide block 3. The at least two clamping mechanisms 5 have the same structure and function, and the number of clamping mechanisms 5 and tension sensors 4 are the same and correspond one-to-one. The clamping mechanism 5 is disposed on the side of the top of the mounting base 1 away from the telescopic device 2. The telescopic device 2 is an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod.

[0020] Example 1: Two short sections of yarn are cut from the yarn to be tested. The two sections are passed through two hanging loops 6, with the yarn lengths on both sides of the same hanging loop 6 being the same. The ends of the yarn are clamped and fixed by the clamping mechanism 5, ensuring that the yarn section between the clamping mechanism 5 and the hanging loop 6 is taut. The tension values ​​of the two tension sensors 4 on the two yarns to be tested are consistent (to ensure consistency, the detected value is greater than 0). Then, the telescopic device 2 is activated, and the slide block 3 drives the two tension sensors 4 to pull the yarn away from the clamping mechanism 5, further facilitating the detection of yarn tension. Furthermore, by selecting the same yarn, applying the same tension, and testing at the same time, the displayed detection values ​​can be compared and referenced, making it easier to accurately determine the yarn tension value and resulting in more accurate test data. Figure 1 (as shown);

[0021] Example 2: Two short sections of yarn are cut from the yarn to be tested. The two sections are passed through two hanging loops 6, and the ends of the yarns are clamped onto two clamping mechanisms 5, ensuring that the yarn sections between the clamping mechanisms 5 and the hanging loops 6 are taut. The tension values ​​of the two tension sensors 4 on the two yarns to be tested are kept consistent (to ensure consistency, the measured value is greater than 0). Then, the telescopic device 2 is activated, and the slide block 3 drives the two tension sensors 4 to pull the yarn away from the clamping mechanisms 5, further facilitating the detection of yarn tension. Furthermore, by selecting the same yarn, applying the same tension, and testing at the same time, the displayed values ​​can be compared and referenced, making it easier to accurately determine the yarn tension value and resulting in more accurate test data. Figure 2 (as shown);

[0022] Furthermore, the yarn tension detection device can directly take a section of yarn, pass the yarn through the hanging ring 6, clamp the two ends of the yarn onto the two clamping mechanisms 5 respectively, activate the telescopic device 2, and the slide 3 drives the tension sensor 4 to pull the yarn away from the clamping mechanism 5, making it easy to detect the yarn tension.

[0023] As a technical optimization of this utility model, the clamping mechanism 5 includes a clamping frame 8 vertically arranged on the top of the mounting base 1 in the shape of a frame, a lower clamping plate 9 arranged at the bottom inside the clamping frame 8, and an upper clamping plate 10 arranged above the lower clamping plate 9. The upper clamping plate 10 is slidably connected to the clamping frame 8. The clamping frame 8 is provided with a threaded rod 11 with a handle at one end. One end of the threaded rod 11 is threaded through the clamping frame 8 and rotatably connected to the upper clamping plate 10.

[0024] In this embodiment: rotating the threaded rod 11 causes the upper clamping plate 10 to move. The upper clamping plate 10 cooperates with the lower clamping plate 9 to easily clamp and fix the yarn to be tested. The distance between the upper clamping plate 10 and the lower clamping plate 9 is easy to adjust, further enabling the clamping mechanism 5 to clamp and fix yarns of different thicknesses.

[0025] As a technical optimization of this utility model, the clamping frame 8 has symmetrical grooves 12 on both sides along the height direction, and a slider 13 fixedly connected to the upper clamping plate 10 is slidably arranged in the grooves 12.

[0026] In this embodiment: when the rotating threaded rod 11 adjusts the height of the upper clamping plate 10, the sliders 13 on both sides of the upper clamping plate 10 are restricted by the sliding groove 12, so that the upper clamping plate 10 can only move up and down and cannot rotate, which makes it easy to clamp and fix the yarn.

[0027] As a technical optimization of this utility model, the lower clamping plate 9 and the upper clamping plate 10 are provided with wavy ridges 14 on opposite sides.

[0028] In this embodiment, the wave ridge 14 further enhances the stability of the yarn clamping by the lower clamping plate 9 and the upper clamping plate 10, thereby improving the clamping effect.

[0029] As a technical optimization of this utility model, a limiting groove 15 is provided on the top of the mounting base 1 along the length direction, and a limiting block 16 that is fixedly connected to the bottom of the slide block 3 is slidably provided in the limiting groove 15.

[0030] In this embodiment, when the slide block 3 slides, the bottom limiting block 16 is restricted by the limiting groove 15, which further improves the stability of the slide block 3 movement.

[0031] Working principle and usage process of this utility model:

[0032] The yarn to be tested is cut into two small segments, and the two segments are passed through two hanging loops 6 respectively, with the yarn lengths on both sides of the same hanging loop 6 being the same. The ends of the yarn are passed through the clamping frame 8 and placed above the lower clamping plate 9. The threaded rod 11 is rotated, and the upper clamping plate 10 moves downward, so that the upper clamping plate 10 cooperates with the lower clamping plate 9, making it easier to clamp and fix the yarn. The wavy edge 14 increases the resistance between the yarn and the upper and lower clamping plates 10 and 9, which makes it easier to improve the stability of the yarn clamping. During clamping, the yarn segment between the clamping mechanism 5 and the hanging loop 6 is kept straight. In this state, the tension values ​​of the two tension sensors 4 on the two yarns to be tested are consistent (to ensure that the values ​​are consistent, the detected values ​​are greater than 0). Then, the telescopic device 2 is activated, and the slide block 3 drives the two tension sensors 4 to pull the yarns away from the clamping mechanism 5, which makes it easier to detect the yarn tension. Furthermore, by selecting the same yarns, applying the same tension, and testing at the same time, the displayed detection values ​​can be compared and referenced, making it easier to accurately determine the yarn tension value and making the detection data more accurate.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
