At this time, the elasticity of the elastic yarn is weakened, and the elastic yarn is arranged in order on the weft accumulator.

Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a tension control device for elastic yarn on an air-jet loom. Background Technology

[0002] Air-jet looms are shuttleless looms that use jet airflow to guide the weft yarn through the shed. The working principle is to use air as the weft-guiding medium; the compressed airflow generated by the jet creates frictional traction on the weft yarn, pulling it through the shed. The jet of air achieves the purpose of weft insertion.

[0003] Currently, when using air-jet looms to weave elastic fabric, the weft yarns are elastic yarns, which often cause the weft yarns to be irregularly arranged or tangled in the weft feeder after entering the weft feeder. This results in poor weft insertion, an increase in the number of weft breaks, and thus affects production efficiency and product quality. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention aims to provide a tension control device for elastic yarn on an air-jet loom, which enables the elastic weft yarn to be arranged on the weft feeder, thereby reducing the number of weft stops and improving product quality.

[0005] To achieve the above-mentioned objective, the present invention provides a tension control device for elastic yarn on an air-jet loom, comprising a screw, a first nut threadedly connected to the surface of the screw, a first ceramic yarn guide disc fitted to the right side of the first nut and the surface of the screw, a spring sleeved on the surface of the screw, a second ceramic yarn guide disc fitted to the left side of the spring and the surface of the screw, a second nut threadedly connected to the surface of the screw, a worm gear fixedly connected to the surface of the second nut, and electric adjusters fitted to the left and right sides of the second nut, the right side of the spring, and the surface of the screw, the electric adjusters meshing with the worm gear, and a strip groove formed on the left side of the screw, the inner wall of the strip groove fitting to the surface of the electric adjuster.

[0006] Furthermore, the electric regulator includes a first ring, a second ring, a first column, a second column, a connecting column, a support plate, a micro motor, a worm gear, a bearing, and a first connecting block. The inner walls of the first ring and the second ring are both in contact with the surface of the screw. The front and rear ends of the first column are fixedly connected to the inner wall of the first ring, and the front and rear ends of the second column are fixedly connected to the inner wall of the second ring. The surfaces of the first column and the second column are both in contact with the inner wall of the slot. The left side of the first ring is in contact with the right side of the spring, and the left and right sides of the second nut are... The first ring and the second ring are respectively attached to the right side and the left side of the second ring. The bottom of the first ring and the bottom of the second ring are fixedly connected to the top of the connecting post. The bottom of the connecting post is fixedly connected to the upper surface of the support plate. The upper surface of the support plate is fixedly connected to the bottom of the micro motor. The output end of the micro motor is fixedly connected to one end of the worm gear through a coupling. The worm gear and the worm wheel mesh with each other. The surface of the worm gear is fixedly connected to the inner ring of the bearing. The outer ring of the bearing is fixedly connected to the inner wall of the first connecting block. The bottom of the first connecting block is fixedly connected to the upper surface of the support plate.

[0007] Furthermore, a third column is fixedly connected to both the front and rear sides of the inner wall of the first ceramic yarn guide plate and both the front and rear sides of the inner wall of the second ceramic yarn guide plate, and the surface of the third column is in contact with the inner wall of the strip groove.

[0008] Furthermore, a second connecting block is fixedly connected to the surface of the screw, and a scale is fixedly connected to the front of the second connecting block. A hollow cylinder is fitted onto the surface of the scale, and the upper surface of the hollow cylinder is fixedly connected to the bottom of the support plate. An observation hole is provided on the front of the hollow cylinder.

[0009] Furthermore, the first nut has a positioning hole inside, the screw has a threaded hole inside, and a positioning bolt is threadedly connected to the inner wall of the threaded hole, with the surface of the positioning bolt fitting against the inner wall of the positioning hole.

[0010] Furthermore, a marking groove is provided on the left side of the screw, and an indicator block is fixedly connected to the left side of the first nut.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The spring pushes the second ceramic yarn guide plate, causing the first and second ceramic yarn guide plates to apply a squeezing force to the elastic yarn between them. This squeezing force straightens the elastic yarn as it passes between the first and second ceramic yarn guide plates, thus reducing its elasticity and allowing it to be neatly arranged on the weft feeder. Simultaneously, the position of the second nut is automatically adjusted through the cooperation of the screw, the second nut, the worm gear, the electric adjuster, and the slot. Adjusting the position of the second nut changes the squeezing force applied to the elastic yarn by the first and second ceramic yarn guide plates.

[0012] 2. By cooperating with the positioning hole, threaded hole, and positioning bolt, the first nut on the screw can be locked, thus preventing the first nut from shifting during the use of the tension control device. At the same time, when the marking groove is aligned with the indicator block, the positioning hole is aligned with the threaded hole; when the marking groove is misaligned with the indicator block, the positioning hole is misaligned with the threaded hole. Thus, through the cooperation of the marking groove and the indicator block, the operator can intuitively judge whether the positioning hole and the threaded hole are aligned.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13As shown, in the present invention, a screw 1 of an air-jet loom elastic yarn tension control device is threadedly connected to a first nut 2. A first ceramic yarn guide 3 is attached to the right side of the first nut 2 and the surface of the screw 1. A spring 4 is sleeved on the surface of the screw 1. A second ceramic yarn guide 5 is attached to the left side of the spring 4 and the surface of the screw 1. A second nut 6 is threadedly connected to the surface of the screw 1. A worm gear 7 is fixedly connected to the surface of the second nut 6. Electric adjusters 8 are attached to the left and right sides of the second nut 6, the right side of the spring 4, and the surface of the screw 1. The electric adjusters 8 mesh with the worm gear 7. A strip groove 9 is opened on the left side of the screw 1. The inner wall of the strip groove 9 is attached to the surface of the electric adjuster 8.

[0030] Preferably, the electric regulator 8 includes a first ring 801, a second ring 802, a first column 803, a second column 804, a connecting column 805, a support plate 806, a micro motor 807, a worm gear 808, a bearing 809, and a first connecting block 810. The inner walls of the first ring 801 and the second ring 802 are both in contact with the surface of the screw 1. The front and rear ends of the first column 803 are fixedly connected to the inner wall of the first ring 801. The front and rear ends of the second column 804 are both fixedly connected to the inner wall of the second ring 802. The surfaces of the first column 803 and the second column 804 are both in contact with the inner wall of the strip groove 9. The left side of the first ring 801 is in contact with the right side of the spring 4. The second nut 6... The left and right sides are respectively attached to the right side of the first ring 801 and the left side of the second ring 802. The bottom of the first ring 801 and the bottom of the second ring 802 are fixedly connected to the top of the connecting post 805. The bottom end of the connecting post 805 is fixedly connected to the upper surface of the support plate 806. The upper surface of the support plate 806 is fixedly connected to the bottom of the micro motor 807. The output end of the micro motor 807 is fixedly connected to one end of the worm 808 through a coupling. The worm 808 meshes with the worm wheel 7. The surface of the worm 808 is fixedly connected to the inner ring of the bearing 809. The outer ring of the bearing 809 is fixedly connected to the inner wall of the first connecting block 810. The bottom of the first connecting block 810 is fixedly connected to the upper surface of the support plate 806.

[0031] It should be noted that the first ceramic yarn guide plate 3 can be limited by the cooperation of the first nut 2 and the screw 1. At the same time, when the elastic yarn is located between the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5, the spring 4 pushes the second ceramic yarn guide plate 5, so that the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5 apply a squeezing force to the elastic yarn. The squeezing force will straighten the elastic yarn when it passes between the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5. At this time, the elasticity of the elastic yarn will be weakened, so that the elastic yarn will be neatly arranged on the weft feeder.

[0032] The micro motor 807 drives the worm gear 808 to rotate. When the worm gear 808 rotates, the second nut 6 rotates through the cooperation of the worm gear 808 and the worm wheel 7. The position of the second nut 6 can be changed through the cooperation of the second nut 6 and the screw 1. At this time, by changing the position of the second nut 6, the magnitude of the squeezing force applied to the elastic yarn by the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5 can be changed. At the same time, through the cooperation of the first column 803, the second column 804 and the strip groove 9, the electric adjuster 8 can not rotate on the screw 1.

[0033] Since both the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5 are made of ceramic, the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5 are not easily worn or burred.

[0034] The front and rear sides of the inner wall of the first ceramic yarn guide plate 3 and the front and rear sides of the inner wall of the second ceramic yarn guide plate 5 are fixedly connected to the third column 10, and the surface of the third column 10 is in contact with the inner wall of the strip groove 9.

[0035] It should be noted that the cooperation between the third column 10 and the strip groove 9 prevents the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5 from rotating on the screw 1.

[0036] A second connecting block 11 is fixedly connected to the surface of the screw 1. A scale 12 is fixedly connected to the front of the second connecting block 11. A hollow cylinder 13 is fitted onto the surface of the scale 12. The upper surface of the hollow cylinder 13 is fixedly connected to the bottom of the support plate 806. An observation hole 14 is provided on the front of the hollow cylinder 13.

[0037] It should be noted that by observing the scale inside the observation hole 14, the distance between the second nut 6 and the second connecting block 11 can be directly determined, and based on the distance between the second nut 6 and the second connecting block 11, the magnitude of the squeezing force applied to the elastic yarn by the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5 can be roughly calculated.

[0038] The first nut 2 has a positioning hole 15 inside, the screw 1 has a threaded hole 16 inside, the inner wall of the threaded hole 16 is threaded with a positioning bolt 17, the surface of the positioning bolt 17 fits with the inner wall of the positioning hole 15, the left side of the screw 1 has a marking groove 18, and the left side of the first nut 2 is fixedly connected with an indicator block 19.

[0039] It should be noted that after the positioning bolt 17 is inserted into the positioning hole 15, it can be fixed in the positioning hole 15 by screwing the positioning bolt 17 into the threaded hole 16. The first nut 2 on the screw 1 can be locked by the cooperation between the positioning bolt 17 and the positioning hole 15, so that the first nut 2 will not be displaced during the use of the tension control device. At the same time, when the marking groove 18 is aligned with the indicator block 19, the positioning hole 15 is aligned with the threaded hole 16. When the marking groove 18 and the indicator block 19 are misaligned, the positioning hole 15 and the threaded hole 16 are misaligned. Thus, the cooperation between the marking groove 18 and the indicator block 19 allows the operator to intuitively judge whether the positioning hole 15 and the threaded hole 16 are aligned.

[0040] The working principle of this invention is as follows: First, the right end of the screw 1 is fixed at a designated position on the air-jet loom. Then, the elastic yarn is placed between the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5. At this time, the spring 4 pushes the second ceramic yarn guide plate 5, causing the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5 to apply a squeezing force to the elastic yarn. Then, the elastic yarn is straightened when it passes between the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5 through the squeezing force. At this time, the elasticity of the elastic yarn is weakened, and the elastic yarn is arranged neatly on the weft feeder.

[0041] When it is necessary to adjust the squeezing pressure applied to the elastic yarn by the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5, the worm 808 is first driven to rotate by the micro motor 807. Then, through the cooperation of the worm 808 and the worm wheel 7, the second nut 6 rotates. At this time, through the cooperation of the second nut 6 and the screw 1, the position of the second nut 6 can be changed. By adjusting the position of the second nut 6, the squeezing pressure applied to the elastic yarn by the first ceramic yarn guide plate 3 and the second ceramic yarn guide plate 5 can be changed.

[0042] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
