Therefore, they should not be construed as limitations on this utility model.
[0037] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0038] Example:
[0039] See Figure 1 and Figure 2 This embodiment discloses a weaving yarn clamping device, including a support plate 10, a base plate 20, a pressure plate 30, and an annular plate 40. Specifically, the support plate 10 is arranged in a horizontal direction, and a support rod 50 is provided on one end of the support plate 10. The support rod 50 is arranged in a vertical direction and is perpendicular to the surface of the support plate 10.
[0040] The base plate 20 has a ring structure. The base plate 20 passes through the support rod 50 and is set at the bottom of the support rod 50. The top of the base plate 20 is flat, and the outer side of the base plate 20 has a downward curved structure.
[0041] The structure of the pressure plate 30 is similar to that of the base plate 20. The pressure plate 30 has a movable hole in the middle and is fitted onto the support rod 50, allowing it to move up and down on the support rod 50. The outer edge of the pressure plate 30 has an upwardly curved structure, and the bottom surface of the pressure plate 30 is parallel to the top surface of the base plate 20. Depending on the position of the pressure plate 30 on the support rod 50, a certain gap can be created between the pressure plate 30 and the base plate 20.
[0042] A plurality of annular plates 40 are disposed on the support rod 50, and the annular plates 40 are pressed against the top of the pressure plate 30.
[0043] In this embodiment, the gap between the pressure plate 30 and the bottom plate 20 allows the yarn to pass through. The pressure plate 30 and the ring plate 40 provide a certain pressure to the yarn, thereby changing the speed of the yarn movement and changing the tension of the yarn while keeping the traction force at the front end of the yarn constant.
[0044] During use, the yarn is passed between the base plate 20 and the pressure plate 30. Then, for fine yarns that require high tension, an annular plate 40 is added to the pressure plate 30. The weight of the annular plate 40 increases the pressure of the pressure plate 30 on the yarn, thereby increasing the tension.
[0045] When the roving passes through the yarn clamp, the required tension is reduced, which can be achieved by reducing the number of annular plates 40 on the pressure plate 30.
[0046] This technical solution allows for adaptive adjustment of the tension of the yarn clamp, thereby improving fabric quality.
[0047] In one specific embodiment:
[0048] The yarn clamp also includes a guide plate 60, which is mounted on one end of the support plate 10, and the surface of the guide plate 60 is perpendicular to the surface of the support plate 10. A guide hole is located in the middle of the guide plate 60, directly opposite the gap between the base plate 20 and the pressure plate 30, and both ends of the guide hole have rounded chamfers.
[0049] During use, the yarn passes through the guide hole in the middle of the lead plate 60 and then through the gap between the base plate 20 and the pressure plate 30.
[0050] In this embodiment, by setting the lead plate 60, the position of the yarn entering the gap between the base plate 20 and the pressure plate 30 can be guaranteed, thereby ensuring the length of the yarn within the gap between the base plate 20 and the pressure plate 30. Furthermore, when adjusting the tension of the yarn clamp, the number of annular plates 40 can be precisely controlled.
[0051] In another specific embodiment:
[0052] The yarn clamp also includes a pressure boosting column 70, which is movably mounted on the support plate 10. The length of the pressure boosting column 70 is rectangular and perpendicular to the surface of the support plate 10. The movement trajectory of the pressure boosting column 70 on the support plate 10 is arc-shaped.
[0053] Specifically, an arc-shaped groove is provided on the support plate 10, and the bottom end of the booster column 70 is movably disposed within the arc-shaped groove. A connecting rod is provided at the bottom end of the booster column 70, forming an L-shaped structure with the booster column 70. The end of the connecting rod away from the booster column 70 is rotatably disposed on the support plate 10, and the rotatable connection point between the connecting rod and the support plate 10 is on the extension line of the support rod 50, allowing the booster column 70 to move around the support rod 50.
[0054] In this embodiment, if the tension of the yarn clamp still cannot meet the requirements after placing multiple annular plates 40 on the pressure plate 30, the yarn can be bypassed around the pressure boosting column 70. On the one hand, the tension is increased by increasing the length of the yarn between the base plate 20 and the pressure plate 30, and on the other hand, the tension is increased by the friction between the yarn and the pressure boosting column 70.
[0055] In another specific embodiment:
[0056] The yarn clamp also includes a tension increasing part 80, which is disposed on one end of the support plate 10. The tension increasing part 80 and the lead plate 60 are respectively located at both ends of the support plate 10, and the aforementioned support rod 50 is close to the lead plate 60.
[0057] A channel is provided in the tension increasing part 80. The channel is arranged in the horizontal direction. After the yarn passes through the guide hole in the middle of the lead plate 60, it passes through the gap between the bottom plate 20 and the pressure plate 30, and selectively allows the yarn to bypass the pressure boosting column 70, and then allows the yarn to pass through the channel of the tension increasing part 80.
[0058] In this embodiment, the tension increasing part 80 is designed to increase the tension of the yarn.
[0059] Specifically, the tension increasing part 80 includes a connecting plate 81, a movable plate 82, a spring 83, a counterweight 84, a mounting plate 85, a support foot 86, a connecting column 87, and a support block 88. Specifically, one end of the connecting plate 81 is fixedly mounted on one end of the support plate 10, and the length direction of the connecting plate 81 is consistent with the length direction of the support plate 10.
[0060] Multiple movable slots are provided on the connecting plate 81, and a movable plate 82 is provided in each movable slot. The movable plate 82 has a through hole in the middle. The through holes on all the movable plates 82 form the channel of the tension increasing part 80.
[0061] A mounting plate 85 is provided at the bottom of all the connecting plates 81. The mounting plate 85 is set in the horizontal direction. A connecting post 87 is vertically provided in the middle of the mounting plate 85. A support block 88 is fixedly provided at the end of the connecting post 87 away from the mounting plate 85. One or more support blocks 88 can be placed on the support block 88.
[0062] Multiple springs 83 are provided between the mounting plate 85 and the connecting plate 81. One end of the spring 83 is fixedly set on the corner of the mounting plate 85, and the other end is set in a vertically downward direction and fixedly installed on one end of the support foot 86. The support foot 86 has an L-shaped structure, and the other end of the support foot 86 is fixedly installed on the connecting plate 81.
[0063] Generally, a spring 83 and a support foot 86 are installed at each of the four corners of the mounting plate 85.
[0064] In this embodiment, four springs 83 support the mounting plate 85 and the movable plate 82 on the connecting plate 81, and make the through holes on all the movable plates 82 at a suitable height. Under this height condition, the yarn extends horizontally and passes through the middle of the through hole without contact between the yarn and the inner wall of the through hole.
[0065] When the tension provided by the base plate 20 and the pressure plate 30 is insufficient, the counterweight 84 is placed on the support block 88, causing all the movable blocks to move downwards and press the yarn downwards, thereby providing the corresponding tension.
[0066] Preferably, the counterweight 84 has a U-shaped notch, so that the counterweight 84 can press on the support block 88 relatively evenly.
[0067] In another specific embodiment:
[0068] During use, the tension between the base plate 20 and the pressure plate 30 is first adjusted using the ring plate 40. When the tension between the base plate 20 and the pressure plate 30 is adjusted to the maximum, the tension of the yarn is increased by placing a counterweight 84 on the support block 88. If the tension is still insufficient at this time, the yarn is made to pass around the pressure booster column 70.
[0069] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
