Description

Technical Field

[0001] The utility model belongs to the technical field of weaving, and in particular relates to a yarn tension self-adjusting device and a weaving system. Background Art

[0002] When weaving two or more layers of fabric with complex patterns on a jacquard loom, some yarns often float up during the interweaving process due to low tension, or the yarns are straightened or even broken due to high tension. Workers stopping the machine to cause yarn knotting will not only affect production efficiency but also cause waste of raw materials. The woven fabric surface will have protrusions and depressions in some places, and the overall look is particularly uneven, affecting the overall appearance. Implant-type woven materials will bleed or the threads will not be absorbed by the human body if used in human experiments later, which is very dangerous. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a yarn tension self-adjusting device and a weaving system. The utility model can adjust the yarn tension, solve the problems of raw material waste, reduced production efficiency, uneven fabric surface, and potential subsequent safety, thereby achieving the effect of reducing costs and increasing efficiency, and improving the quality of woven fabric surface.

[0004] The technical solution provided by the utility model is as follows:

[0005] A yarn tension self-adjusting device, comprising at least:

[0006] A second-stage tension adjustment device, the second-stage tension adjustment device comprising two left and right guide wheels, and a tension wheel that can move up and down and is arranged below the two guide wheels;

[0007] A tension ring, through which the yarn passes and around the tension wheel;

[0008] and a first-stage tension adjusting device, wherein the first-stage tension adjusting device can pull the tension ring in a direction away from the tension wheel.

[0009] Based on the above technical solution:

[0010] The first-stage tension adjustment can be performed through the first-stage tension adjustment device, and the second-stage tension adjustment can be performed through the second-stage tension adjustment device;

[0011] When the tension increased or decreased by the first-stage tension adjustment is insufficient, the tension can be further increased or decreased by the second-stage tension adjustment to make up for it.

[0012] Specifically, the second-stage tension adjustment device has a vertical moving device, and the moving end of the vertical moving device rotates and connects the rotating shaft of the tension wheel. The vertical moving device can adopt existing technology, such as a screw nut mechanism, or a linear module.

[0026] Specifically, the yarn tube is arranged on a horizontal surface, and the guide wheel is arranged just above the horizontal surface.

[0027] The utility model also provides a weaving system, which at least comprises the yarn tension self-adjusting device.

[0037] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0038] Example 1

[0039] like Figure 1 As shown, the yarn tension self-adjusting device at least includes a second-stage tension adjusting device 5, a first-stage tension adjusting device and a tension ring 11. The second-stage tension adjusting device 5 includes two left and right guide wheels, and a tension wheel 6 that can move up and down and is arranged below the two guide wheels. The yarn 3 passes through the tension ring 11 and bypasses the tension wheel 6. The first-stage tension adjusting device can pull the tension ring 11 in a direction away from the tension wheel 6.

[0040] Based on this technical solution, two-level tension adjustment can be achieved, and the primary adjustment can be supplemented by the secondary adjustment.

[0041] Example 2

[0042] On the basis of Example 1, Figure 1 As shown, the yarn tension self-adjusting device comprises a yarn tube 2, a guide wheel 4, a second-stage tension adjusting device 5 and a heald 10 with a heald hole, which are arranged in sequence, and the first-stage tension adjusting device is arranged on one side of the second-stage tension adjusting device 5. The yarn tube 2 is arranged on a horizontal surface 1, and the guide wheel 4 is placed just above the horizontal surface 1. The tension ring 11 is close to the lower end surface of the tension wheel 6.

[0043] Based on this technical solution, the yarn tension can be adjusted to achieve the effects of reducing costs, increasing efficiency, and improving the quality of woven fabrics.

[0044] Example 3

[0045] On the basis of Example 1, Figure 1 As shown, the second-stage tension adjustment device 5 has a vertical moving device, and the moving end of the vertical moving device rotates the shaft connected to the tension wheel 6. Based on this technical solution, the tension can be adjusted by moving the tension wheel up and down.

[0046] Example 4

[0047] On the basis of Example 1, Figure 1 As shown, the first-stage tension adjustment device includes a fixed winding device 9, on which a first connecting guide wire 8 is wound, one end of the first connecting guide wire 8 is fixedly connected to one end of a horizontally arranged spring 7, and the other end of the spring 7 is fixedly connected to a tension ring 11 through a second connecting guide wire 12. The first connecting guide wire 8 is horizontally arranged. The second connecting guide wire 12 is horizontally arranged.

[0048] Based on this technical solution, the spring can be pulled by the winding device, thereby pulling the tension ring.

[0049] Example 5

[0050] On the basis of Example 1, the yarn tension self-adjusting device includes a controller, and the controller is respectively connected to the winding device 9 and the vertical moving device.

[0051] Example 6

[0052] On the basis of Example 1, the yarn tension self-adjusting device is provided with a yarn tension measuring device, and the yarn tension measuring device is connected with a display, and the display is fixedly arranged on the frame of the second-level tension adjusting device 5 .

[0053] During the weaving process, the yarn 3 on the yarn tube 2 is quantitatively unwound according to the weaving speed and transmitted along the guide wheel 4 to the weaving direction of the heald 10 with heald holes. Before formal weaving, the yarn tension is adjusted to an appropriate range until the woven fabric surface is intact, and the upper and lower limits of the tension are set in the tension display. When the yarn is relaxed and the tension value of the tension display is lower than the lower limit of the tension range, it is preferentially adjusted through the spring 7, and the winding device 9 can be started in a chain manner so that the connected guide wire begins to be tightened clockwise until the tension value of the tension display is within the range. If the winding device 9 has been wound to the limit and the tension is still too small, the tension wheel 6 of the secondary device is started to move down until the tension is adjusted to an appropriate range; if the tension display value is higher than the upper limit of the tension range, the winding device 9 of the guide wire is started in a chain manner so that "9" begins to relax clockwise until the tension value of the tension display is within the range. If the guide wire of the winding device 9 has been relaxed to the limit and the tension is still too large, the guide wheel that slides up and down the tension wheel 6 of the secondary device is started to move up until the tension is adjusted to an appropriate range; if all devices have reached their limits, the alarm device will eventually be activated, the equipment will be shut down, and manual intervention will be required to adjust to an appropriate state.
