Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, and in particular to a tension adjustment mechanism for a fully automatic wire drawing machine. Background Technology

[0002] When producing spun products, different thicknesses of yarn are needed depending on the product specifications. Since a single yarn is relatively thin, to obtain a thicker yarn, multiple yarns need to be twisted and combined. Therefore, a yarn combining machine is required. When the yarn is combined through the yarn combining machine, multiple fine yarns are combined into a thicker yarn.

[0003] Traditional twinning machines cannot precisely adjust the tension of the yarn. If the tension is too high during processing, the yarn is prone to breakage; if the tension is too low, the yarn is prone to loosening and tangling, affecting the yarn processing. Utility Model Content

[0004] This application provides a tension adjustment mechanism for a fully automatic yarn doubling machine, which can solve the problem that traditional yarn doubling machines cannot accurately adjust the tension of the yarn, which may result in excessive tension causing yarn breakage or insufficient tension causing yarn loosening and tangling, thus affecting the overall processing.

[0005] This application provides a tension adjustment mechanism for a fully automatic twinning machine, comprising a mounting plate. The mounting plate has several mounting slots, in which an adjustment component is installed. A positioning rod is mounted on the adjustment component, a guide wheel is mounted on the positioning rod, a pressure sensor is mounted on the guide wheel, and a display is mounted on the mounting plate. The pressure sensor and the display are connected via a wireless module.

[0006] Furthermore, a limiting groove is formed on the guide wheel, and the two ends of the limiting groove are inclined. The pressure sensor is installed in the limiting groove.

[0007] Furthermore, the adjustment assembly includes a threaded rod, a hand crank, and a slider. The threaded rod is rotatably connected to the mounting groove, the slider is disposed on the threaded rod, and the hand crank is fixedly connected to the threaded rod.

[0008] Furthermore, a first gear is fixedly connected to the threaded rod, and a second gear is provided on one side of the first gear. The first gear and the second gear mesh with each other, and the second gear is rotatably connected to the mounting plate.

[0009] Furthermore, a support block is fixedly connected to the slider, a pin is fixedly connected to the support block, and a groove is provided on the guide wheel to cooperate with the pin.

[0010] Furthermore, the support block is divided into a fixed block and a movable block. The fixed block is fixedly connected to the slider, and the movable block slides within the fixed block. The fixed block and the movable block are fixed together by bolts.

[0011] In summary, the beneficial effects of the tension adjustment mechanism of the fully automatic yarn twisting machine in this application are: flexible adjustment and strong applicability. The position of the positioning rod and guide wheel can be easily adjusted through the adjustment component in the mounting slot. The pressure sensor on the guide wheel, together with the display on the mounting plate, transmits tension data in real time through the wireless module. The operator can intuitively understand the yarn tension and make timely adjustments. This effectively avoids the problem of yarn breakage due to excessive tension or yarn tangling due to insufficient tension, ensuring the quality of yarn processing and achieving accurate monitoring and control of tension.

[0014] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0015] like Figures 1 to 4As shown, a tension adjustment mechanism for a fully automatic twinning machine includes a mounting plate 1. Several mounting slots 2 are evenly distributed along the length of the mounting plate 1. An adjustment component 3 is installed in each mounting slot 2. A positioning rod 4 is fixedly connected to the adjustment component 3. A guide wheel 5 is mounted on the positioning rod 4. The guide wheel 5 rotates on the positioning rod 4. Starting from the leftmost positioning rod 4 on the mounting plate 1, the length of each subsequent positioning rod 4 is longer than two-thirds of the length of the positioning rod 4 on the left, and so on. This ensures that the guide wheel 5 on each positioning rod 4 is rotated. The guide rollers 5 are staggered to prevent the yarns on them from tangling. Each guide roller 5 is equipped with a pressure sensor 6, and each pressure sensor 6 corresponds to a display 7. The display 7 is fixedly connected to the mounting plate 1. The pressure sensor 6 senses the pressure between the guide roller 5 and the yarn and transmits the pressure value to the display 7, which displays the value. This ensures that the tension of yarns of different qualities on the guide roller 5 is accurate. The pressure sensor 6 and the display 7 are connected by a wireless module, which can be a Bluetooth module, a WiFi module, or other similar modules.

[0016] Furthermore, such as Figure 4 As shown, a limiting groove 8 is provided on the guide wheel 5, and the pressure sensor 6 is fixedly connected to the bottom of the limiting groove 8. The two ends of the limiting groove 8 are inclined, which can ensure that the yarn can be blocked by the limiting groove 8 during the movement, so that the yarn is always on the guide wheel 5.

[0017] Furthermore, such as Figure 1 and Figure 3 As shown, the adjusting assembly 3 includes a threaded rod 301, a handwheel 302, and a slider 303. The threaded rod 301 is located in the mounting groove 2, with one end abutting the bottom of the mounting groove 2 and rotating around the center of this abutment point. The other end of the threaded rod 301 extends out of the mounting groove 2. The handwheel 302 is fixedly connected to this end of the threaded rod 301, and is used to rotate the threaded rod 301. The slider 303 is mounted on the threaded rod 301, and is threadedly connected to the threaded rod 301. The positioning rod 4 is fixedly connected to the slider 303. A gear 9 is provided between 302 and the upper surface of the mounting plate 1. Gear 9 is fixedly connected to the threaded rod 301. A gear 10 is provided on one side of gear 9. Gear 10 is rotatably connected to the upper surface of the mounting plate 1. Gear 9 and gear 10 mesh, and the diameter of gear 9 is larger than that of gear 10. By rotating the threaded rod 301 through the hand crank 302, the slider 303 is driven, thereby adjusting the position of the guide wheel 5 on the slider 303, thus realizing the function of adjusting the yarn tension. When fine adjustment is required, gear 10 can be turned, and gear 10 drives gear 9 to rotate, thereby driving the threaded rod 301 to rotate.

[0018] Furthermore, a support plate is fixedly connected to the slider 303. The support plate is divided into a fixed block 121 and a movable block 122. The fixed block 121 is fixedly connected to the slider 303. One end of the movable block 122 slides in the fixed block 121. A pin 12 is fixedly connected to the other end of the movable block 122. A groove 13 that mates with the pin 12 is provided on the guide wheel 5. The fixed block 121 and the movable block 122 are fixed together by bolts. Since the length of the positioning rod 4 is different, the length is longer towards the right. This may cause the positioning rod 4 to wobble. Therefore, in order to avoid the slippage, the wobble of the positioning rod 4 can be stabilized by inserting the pin 12 on the movable block 122 into the groove 13 on the guide wheel 5.

[0019] Working principle of the utility model: When the yarn moves on the guide wheel 5, the pressure sensor 6 at the bottom of the limiting groove 8 senses the pressure between the yarn and the guide wheel 5. This pressure value is transmitted via Bluetooth module and WiFi. The wireless module transmits data to the corresponding display 7 and displays it to monitor the tension of yarns of different qualities on the guide wheel 5 in real time, ensuring accurate tension. The guide wheel 5 can be adjusted in real time by adjusting the component 3, or it can be adjusted before starting the spinning machine. The adjusting component 3 can adjust the position of the guide wheel 5 in two ways: coarse adjustment and fine adjustment, thereby achieving tension adjustment. In coarse adjustment, the hand crank 302 is turned, which drives the threaded rod 301 to rotate in the mounting groove 2 with the contact point with the bottom of the mounting groove 2 as the center. Since the slider 303 and the threaded rod 301 are connected by threads, the rotation of the threaded rod 301 will cause the slider 303 to move on the threaded rod 301, thereby driving the positioning rod 4 and the guide wheel 5, which are fixedly connected to the slider 303, to change their positions. In fine adjustment, the meshing gear 9 and gear 10 (the diameter of gear 9 is larger than that of gear 10) are used to turn gear 10, which drives gear 9 and the threaded rod 301 to rotate, thereby achieving fine adjustment of the position of the guide wheel 5.
