Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, and in particular to a tension adjustment device for an air-jet loom. Background Technology
[0002] Air jet looms are shuttleless looms that use jet airflow to pull the weft yarn through the shed. The working principle is to use air as the weft insertion medium, and the compressed airflow generated by the jet will generate frictional traction force on the weft yarn to pull it through the shed. The jet generated by the air jet achieves the purpose of weft insertion. This weft insertion method enables the loom to achieve high speed and high output.
[0003] In the prior art, the biggest drawback of air-jet looms, which use airflow weft, is their high energy consumption. The tension of the material in air-jet looms is crucial; whether too high or too low, it will affect normal operation. The aforementioned application (application number 202121478731.9) discloses a tension adjustment device for air-jet looms, comprising a support base and a monitoring mechanism. The monitoring mechanism is located on the top of the support base, and a first adjustment box is fixedly connected to the top of the support base. A first threaded rod is rotatably connected inside the first adjustment box. A second adjustment box is fixedly connected to the bottom of the support base, and a second threaded rod is rotatably connected inside the second adjustment box. Transmission blocks are slidably connected inside both the first and second adjustment boxes. A bracket is fixedly connected to the top of the two transmission blocks. A first adjustment roller is rotatably connected to one side of the bracket via a rotating shaft, and a second adjustment roller is rotatably connected to the other side of the bracket via a rotating shaft. This invention, through its monitoring mechanism, first and second adjustment rollers, first and second adjustment boxes, and motor, can monitor the tension and automatically adjust it when the tension does not meet the set range.
[0004] However, a thorough reading of the aforementioned patent documents reveals the following drawbacks: when conveying the fabric, it is not convenient to limit the width of the fabric, which makes it easy for the fabric to shift when the tension is changed. This can easily cause the fabric to be misaligned when rolling, affecting product quality and leaving room for improvement. Utility Model Content

[0027] Reference Figures 1-5 A tension regulating device for an air-jet loom includes a base 1 and a material 2 mounted on the air-jet loom;
[0028] The base 1 is equipped with an adjustment mechanism 3 for adjusting the tension of the material 2, and a control panel 4 is installed on the base 1. The adjustment mechanism 3 is connected to the control panel 4. The base 1 is welded to one side of the air-jet loom.
[0029] The adjusting mechanism 3 includes a threaded rod 31, an adjusting plate 32, an adjusting roller 33, a limiting component, and a motor 39. Two threaded rods 31 are rotatably connected to the base 1. One end of each threaded rod 31 is threadedly connected to an adjusting plate 32. The same adjusting roller 33 is rotatably connected between the two adjusting plates 32. The material 2 is placed on the adjusting roller 33. A limiting component is provided at one end of each adjusting plate 32. Both limiting components are connected to the adjusting roller 33 and the material 2. Through the coordinated design between the base 1, the adjusting mechanism 3, and the control panel 4, not only can the tension of the material 2 be adjusted, but also the sides of the material 2 can be limited. Furthermore, the material 2 can be extended to both sides to prevent wrinkles from forming.
[0030] In this method, the limiting assembly includes a limiting ring 34, a threaded rod 35, a U-shaped plate 36, a pressure roller 37, and a cylinder 38. A cylinder 38 is fixedly installed at one end of each of the two adjusting plates 32. A limiting ring 34 is installed at the output end of each of the two cylinders 38. The two limiting rings 34 are respectively movably sleeved on both ends of the adjusting roller 33. During operation, the two limiting rings 34 and the adjusting roller 33 are not in contact. Both cylinders 38 are connected to the control panel 4 to limit the two sides of the material 2 and prevent the material 2 from shifting.
[0031] In this method, threaded rods 35 are threadedly connected to both limiting rings 34, and U-shaped plates 36 are rotatably connected to one end of each threaded rod 35. Pressure rollers 37 are rotatably mounted on each of the two U-shaped plates 36. Both pressure rollers 37 are in contact with the material 2 and are used to adjust the distance between the two pressure rollers 37 and the adjusting roller 33, thereby achieving the effect of limiting materials of different thicknesses and improving the applicability.
[0032] In this method, one side of each of the two U-shaped plates 36 is in contact with two limiting rings 34 to prevent the U-shaped plates 36 from rotating with the threaded rod 35.
[0033] In this method, anti-slip rings are fixedly fitted on both pressure rollers 37, and both anti-slip rings are in contact with the material 2 to increase the friction between the pressure rollers 37 and the material 2.
[0034] In this method, one end of each of the two threaded rods 35 is fixedly fitted with a bearing 1, and the outer walls of the two bearings 1 are respectively fixedly connected to the two U-shaped plates 36, so that the two threaded rods 35 can respectively perform threaded transmission with the two limiting rings 34.
[0035] In this method, two sleeves 5 are welded to one side of each of the two limiting rings 34. Each of the four sleeves 5 has a threaded hole. Each of the output ends of the two cylinders 38 has a limiting hole. The two limiting holes correspond to the four threaded holes respectively. Two of the four sleeves 5 are threadedly connected to limiting rods 6. One end of each limiting rod 6 extends into the two limiting holes. Through the action of the two sleeves 5, the two limiting rods 6 and the two limiting holes, the two limiting rings 34 can be rotated half a turn, thereby facilitating the two pressure rollers 37 to limit the material 2 located below the adjusting roller 33, greatly improving flexibility.
[0036] In this method, two motors 39 are fixedly installed at the bottom of the base 1. The output ends of the two motors 39 are respectively fixedly connected to one end of the two threaded rods 31 to drive the two threaded rods 31. Both motors 39 are servo motors, which makes the rotation drive of the two threaded rods 31 more precise.
[0037] In this configuration, both motors 39 are connected to the control panel 4, and one end of each of the two threaded rods 31 is fixedly fitted with a bearing 2. The outer walls of the two bearings 2 are fixedly connected to the base 1, which facilitates the rotation of the two threaded rods 31 on the base 1.
[0038] Working principle: During use, the electric motor 39 and cylinder 38 are driven and controlled by the preset program in the control panel 4;
[0039] First, material 2 is placed on adjusting roller 33. Then, driven by two cylinders 38, two limiting rings 34 are moved a certain distance at one end of adjusting roller 33, and the two limiting rings 34 are in contact with both sides of material 2, and the two pressure rollers 37 are aligned with material 2. Then, by rotating two threaded rods 35 in sequence and under the transmission action of U-shaped plate 36, the pressure rollers 37 are moved towards adjusting roller 33, and the two pressure rollers 37 are in contact with material 2. In summary, the effect of limiting both sides of material 2 is achieved.
[0040] Subsequently, through the contraction drive of two cylinders 38, and with the cooperation of two limit rings 34, threaded rod 35, U-shaped plate 36 and pressure roller 37, the material 2 can be extended to both sides, thereby achieving the effect of adjusting the tension on both sides of the material 2 and avoiding material wrinkling.
[0041] The synchronous drive of two motors 39 causes two threaded rods 31 to rotate synchronously on the base 1 and respectively engage in threaded transmission with two adjusting plates 32, thereby achieving the effect of adjusting the up and down movement of the two adjusting plates 32. At the same time, the transmission of the two adjusting plates 32 can achieve the effect of adjusting the height of the adjusting rollers 33, thereby adjusting the height difference between the adjusting rollers 33, and thus achieving the effect of adjusting the tension of the material 2 during feeding.
[0042] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the tension of material 2 be adjusted, but also the sides of material 2 can be limited, and material 2 can be extended to both sides, preventing wrinkles and greatly improving stability and practicality.
