Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of webbing production, in particular to a device for adjusting the tension of yarns of a weaving machine. Background Art
[0002] During the operation of the ribbon loom, if you want to produce good ribbon, the yarn must be fed in evenly and the tension must be uniform. However, it is not easy to keep the yarn fed in evenly, because when the yarn is in a large roll, it is heavier. Under the action of gravity, the yarn roller is on a horizontal plane. However, when the yarn becomes less, the weight of the yarn roller decreases, and the yarn roller will move upward. At this time, the distance will change, and the tension of the yarn will change, making it impossible to feed the yarn evenly, resulting in poor quality of the produced ribbon and frequent unqualified products.

The sensor records the number of turns of the first guide roller 6. When a certain number of turns is reached, the yarn roller 3 becomes lighter and the gravity decreases after the webbing yarn 4 flows away. The entire yarn roller 3 will move upward. At this time, the webbing yarn 4 becomes loose, and the turn sensor transmits a signal to the PLC controller. The PLC controller controls the electric push rod 21 to move downward, driving the connecting plate 22 downward, thereby driving the telescopic rod 23 and the pressure roller 24 to move downward together. Under the action of the pressure roller 24, the webbing yarn 4 is re-tensioned. This device controls the descending distance of the electric push rod 21 by counting the number of turns by the sensor 14, so that the yarn is always in a tensioned state, so that the yarn can be evenly transported. At the same time, each yarn can play a guiding and positioning role under the action of the positioning groove 12 of the guide plate 11, preventing the yarn from being cross-transported during the transportation process, causing yarn entanglement, and effectively improving the product quality of the webbing.
[0023] Specifically, the sensor 14 is installed on the top of the support frame 5 through the support rod 15. The sensor 14 is a circle number sensor. The sensor 14 and the electric push rod 21 are electrically connected to the external PLC controller. During the period, the circle number sensor records the number of circles of the first guide roller 6. When a certain number of circles is reached, the yarn roller 3 becomes lighter and the gravity decreases after the ribbon yarn 4 flows away. The entire yarn roller 3 will move upward. At this time, the ribbon yarn 4 becomes loose, and the circle number sensor transmits a signal to the PLC controller. The PLC controller controls the electric push rod 21 to move downward, driving the connecting plate 22 downward, thereby driving the telescopic rod 23 and the pressure roller 24 to move downward together. Under the action of the pressure roller 24, the ribbon yarn 4 is re-tensioned.
[0024] Preferably, the adjusting device 2 includes a connecting plate 22, a telescopic rod 23, a pressure roller 24 and a plurality of electric push rods 21. The electric push rods 21 are vertically mounted on the support frame 5. The output end of the electric push rod 21 is connected to the connecting plate 22. Telescopic rods 23 are respectively provided on both sides of the connecting plate 22. Both ends of the pressure roller 24 are rotatably connected to the telescopic rod 23. The pressure roller 24 is pressed tightly against the webbing yarn 4. A compression spring is provided in the telescopic rod 23 to play a buffering role. The entire device is pushed by the electric push rod 21 to achieve the adjustment of the tensioning force of the pressure roller 2 on the webbing yarn 4.
[0025] Furthermore, rollers 9 are rotatably provided on both sides of the connecting plate 22, and the rollers 9 are fitted with the adjusting frame 8, so that the connecting plate 22 can be more stable during the rising and falling process.
[0026] Furthermore, a positioning groove 12 is provided on the guide plate 11. The positioning groove 12 is a U-shaped structure that is wide at the top and narrow at the bottom. Each yarn can be guided and positioned under the action of the positioning groove 12 of the guide plate 11 to prevent the yarn from being cross-conveyed during the conveying process and causing the yarn to be entangled, thereby effectively improving the product quality of the webbing.
[0027] Furthermore, cross beams 13 are provided on both sides of the adjustment frame 8, and the second guide roller 7 is rotatably installed on the cross beam 13 through the vertical plate 16. The cross beam 13 plays a supporting role, and the heights of the cross beams 13 on both sides are consistent, so that the second guide rollers 7 on both sides are located on the same horizontal plane, ensuring that the webbing yarn 4 runs more smoothly under the guidance of the second guide rollers 7 on both sides.
[0028] When the tension device of the present embodiment for adjusting the yarn of the ribbon machine is in use, the yarn flows out from the yarn roller 3, is guided by the first guide roller 6, and then is guided by the two second guide rollers 7. During this period, the number of turns sensor records the number of turns of the first guide roller 6. When a certain number of turns is reached, the yarn roller 3 becomes lighter and the gravity decreases after the ribbon yarn 4 flows away. The entire yarn roller 3 will move upward. At this time, the ribbon yarn 4 becomes loose, and the number of turns sensor transmits a signal to the PLC controller. The PLC controller controls the electric push rod 21 to move downward, driving The connecting plate 22 moves downward, thereby driving the telescopic rod 23 and the pressure roller 24 to move downward together. Under the action of the pressure roller 24, the webbing yarn 4 is re-tensioned. This device controls the descending distance of the electric push rod 21 by the number of turns counted by the sensor 14, so that the yarn is always in a tensioned state, so that the yarn can be evenly transported. At the same time, each yarn can play a guiding and positioning role under the action of the positioning groove 12 of the guide plate 11, preventing the yarn from being cross-transported during the transportation process, causing the yarn to be entangled, and effectively improving the product quality of the webbing. The utility model is a device for adjusting the tension of the yarn of the webbing machine, so that the yarn can be evenly transported, effectively improving the product quality of the webbing, and has the characteristics of wide application range and strong practicality.
[0029] The above is only a preferred embodiment of the present invention.
