Description

Technical Field

[0001] This invention relates to the field of loom manufacturing technology, specifically a water jet loom with warp tension adjustment function. Background Technology

[0002] Water jet looms, as one of the mainstream equipment in high-speed and high-efficiency weaving technology in modern textile industry, work by using high-pressure water jets to pull the weft yarn through the shed formed by the warp yarns, thus completing the warp-weft interlacing. Throughout the weaving process, maintaining uniform and appropriate tension in the warp system is key to ensuring fabric quality, improving production efficiency, and reducing warp breakage rate.

[0003] In existing technologies, warp tension control on water-jet looms mainly relies on mechanical or simple electromechanical passive and semi-active adjustment mechanisms. The most common is a spring-loaded or counterweight lever-type backbeam system. These devices buffer some tension fluctuations caused by changes in the warp beam unwinding diameter through the floating of the backbeam, representing passive compensation. Their core drawbacks are: First, a lack of real-time, precise tension sensing capability. Mechanical backbeams are insensitive to subtle tension changes, with limited adjustment range and precision, making it difficult to quickly and directly fine-tune tension near the weave point. Especially during loom startup, braking, changes in weft density, or handling of different raw materials, the dynamic changes in tension are complex, and traditional systems cannot achieve rapid tracking and precise compensation. Second, poor adaptability and controllability. Faced with diverse yarn materials and fabric structures, differentiated tension settings are required. Existing technologies involve cumbersome adjustment processes, often requiring manual adjustment of relevant mechanical components after machine shutdown, making it difficult to achieve rapid and accurate setting and reproduction of process parameters.

[0004] Therefore, there is a need for an actuator that can detect the tension of warp yarns in real time and with high precision, and can directly affect the tension of yarns in key areas. By directly adjusting the path and length of the warp yarns, the yarns can be tightened or loosened in a timely manner. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Figures 1-7As shown, the present invention provides a technical solution for a water jet loom with warp tension adjustment function. This water jet loom includes a support module 1, a needle bed 2 installed within the support module 1, a tensioning component 3 at the bottom of the needle bed 2, a yarn wheel frame 4 positioned directly above the needle bed 2, the yarn wheel frame 4 fixed to the top of the support module 1, an adjustable comb section 5 installed within the yarn wheel frame 4, and a warp feed component 6 installed on the outside of the support module 1. The support module 1 includes two support plates 11, with a positioning rod 12 connecting the two support plates 11. The needle bed 2 is rotatably connected to the positioning rod 12, and a support rod 13 is installed at the top of the positioning rod 12, which is fixedly connected to the yarn wheel frame 4. First, two rolls of yarn are fixed to the yarn wheel frame 4 via rollers 43, and adjustable comb sections 5 are installed near the two rolls of yarn. Then, one roll of yarn is passed through the comb hole of the nearest adjustable comb section 5. 5501, the yarn is divided into multiple strands through the comb hole 5501 and then passes through the tongue needle 2204 on the front needle plate 2201. Then, it passes under the pressure rod 26 and is inserted into the tongue needle 2204 of the rear needle plate 2202. The other yarn roll also passes through the nearest comb hole 5501 and directly passes the divided yarn through the tongue needle 2204 of the rear needle plate 2202. On the other side, the yarn roll 62 on the yarn feed assembly 6 is also equipped with a yarn roll. The yarn drawn out from the yarn roll 62 passes around the tension shaft 63 in sequence. The tension of this part of the yarn is simply adjusted to prevent the yarn from knotting and being unable to be sprayed out by high pressure water. Then, the yarn is inserted into the guide sleeve 2402 of the movable nozzle 24. The outlet hole of the movable nozzle 24 is always aligned with the center hole of the tongue needle 2204 to ensure that the yarn sprayed out by the movable nozzle 24 can pass smoothly through all the tongue needles 2204 to complete the weaving.

[0020] The yarn drawn from the yarn wheel frame 4 always supports the weight of the pressure rod 26. If the yarn tension is not up to standard, the pressure rod 26 will shift. When the yarn tension is not up to standard, the displacement information of the pressure rod 26 can be captured by the detection spring 2503 and transmitted to the control system. The control system can determine whether the tension is too high or too low, and then control the camshaft 32 to rotate. The rotation of the camshaft 32 can drive the cam 35 to rotate. The cam 35 is connected to the rocker arm roller 3402 and the support roller 3701. Therefore, different rotation directions of the camshaft 32 will cause one side of the front needle plate 2201 on the needle bed 2 to rise or fall. When the yarn tension is detected to be too high, the rotation of the camshaft 32 can lower one side of the front needle plate 2201 to reduce the tension on the yarn. When the yarn tension is detected to be too low, the camshaft 32 can rotate in the opposite direction to raise the front needle plate 2201 to further stretch the yarn, thereby realizing real-time adjustment of the yarn of the water jet loom.

[0023] The adjustable comb section 5 includes a fixed part 51 and a movable part 52. The fixed part 51 is provided with two connecting rods 53, and the connecting rods 53 are provided with a fixed shaft 5301.

The other connecting rod 53 has a pressing groove 5304 at its end, and a pressing spring 5305 is provided in the pressing groove 5304. The fixed part 51 and the movable part 52 are connected by a connecting shaft 54.

The rotating sleeve 3601 is connected to the needle bed connecting rod 3602. The end of the needle bed connecting rod 3602 is connected to the connecting seat 2302 on one side of the rear needle plate 2202. A support rocker arm 37 is provided in the middle of the support shaft 33. A support roller 3701 is provided on the support rocker arm 37. The support roller 3701 is embedded in the cam 35.

[0027] The yarn wheel frame 4 includes symmetrically arranged arc-shaped rods 41, and a number of bushings 42 are evenly arranged on the arc-shaped rods 41. The bushings 42 have a sliding groove 4201 in the middle. The bushings 42 are fixed to the arc-shaped rods 41 by bolts. A roller shaft 43 is arranged inside the yarn wheel frame 4. The roller shaft 43 is fixed to the yarn wheel frame 4 by the bushings 42.

[0028] The warp feeding assembly 6 includes a frame base 61 fixedly mounted on a support plate 11, a yarn wheel 62 installed inside the frame base 61, a plurality of tension shafts 63 provided at the bottom of the yarn wheel 62, and a water tank 64 also provided inside the frame base 61.

[0029] Working principle of the invention: First, two spools of yarn are fixed inside the yarn wheel frame 4 by rollers 43, and adjustable comb sections 5 are installed near the two spools of yarn. Then, one spool of yarn is passed through the comb hole 5501 of the nearest adjustable comb section 5, splitting the yarn into multiple strands through the comb hole 5501, and then passing through the tongue needle 2204 on the front needle plate 2201. Next, it passes under the pressure rod 26 and is inserted into the tongue needle 2204 of the rear needle plate 2202. The other spool of yarn is similarly passed through the nearest comb hole 5501, and the split yarn is directly passed through the rear needle plate 2202. In the latch needle 2204, on the other side, the yarn roll 62 on the yarn feeding assembly 6 is also equipped with a yarn spool. The yarn drawn out from the yarn roll 62 is passed around the tension shaft 63 in sequence. The tension of this part of the yarn is simply adjusted to prevent the yarn from knotting and being unable to be sprayed out by high-pressure water. Then the yarn is inserted into the guide sleeve 2402 of the movable nozzle 24. The outlet hole of the movable nozzle 24 is always aligned with the center hole of the latch needle 2204 to ensure that the yarn sprayed out by the movable nozzle 24 can pass smoothly through all the latch needles 2204 to complete the weaving.

[0030] The yarn drawn from the yarn wheel frame 4 always supports the weight of the pressure rod 26. If the yarn tension is not up to standard, the pressure rod 26 will shift. When the yarn tension is not up to standard, the displacement information of the pressure rod 26 can be captured by the detection spring 2503 and transmitted to the control system. The control system can determine whether the tension is too high or too low, and then control the camshaft 32 to rotate. The rotation of the camshaft 32 can drive the cam 35 to rotate. The cam 35 is connected to the rocker arm roller 3402 and the support roller 3701. Therefore, different rotation directions of the camshaft 32 will cause one side of the front needle plate 2201 on the needle bed 2 to rise or fall. When the yarn tension is detected to be too high, the rotation of the camshaft 32 can lower one side of the front needle plate 2201 to reduce the tension on the yarn. When the yarn tension is detected to be too low, the camshaft 32 can rotate in the opposite direction to raise the front needle plate 2201 to further stretch the yarn, thereby realizing real-time adjustment of the yarn of the water jet loom.

[0031] When the fixed part 51 and the movable part 52 on the adjustable comb section 5 are connected, the ratchet 5402 on the connecting shaft 54 ​​is embedded in the ratchet groove 5202. The angle of the comb section plate 55 can be adjusted by simply moving the movable part 52 upward. Due to the cooperation between the ratchet 5402 and the ratchet groove 5202, the comb section plate 55 is fixed and cannot continue to rotate downward. By fixing the comb section plate 55, the stability of the yarn transmission process can be improved and the yarn tension can be maintained. When it is necessary to adjust the angle of the comb section plate 55, simply press down the part of the connecting shaft 54 ​​that extends. At this time, the ratchet on the connecting shaft 54 ​​is pressed into the annular groove 5203, the ratchet 5402 and the ratchet groove 5202 separate, and the comb section plate 55 returns to the movable state. After the adjustment is completed, simply release the connecting shaft 54. Under the restoring force of the pressing spring 5305, the connecting shaft 54 ​​pops out again, and the ratchet 5402 is also re-embedded in the ratchet groove 5202 to fix the comb section plate 55.

[0032] When the water jet loom is working, the tension rod 26 is supported by the tension of the yarn. When the tension of the yarn changes, the tension rod 26 will be displaced. This displacement is captured by the detection spring 2503, and then the detection plate 25 judges the tension of the yarn. Then, the tensioning component 3 drives the entire needle bed 2 to tilt, thereby changing the length of the yarn and adjusting the tension of the yarn in real time.

[0033] By changing the angle of the adjustable comb section 5, the distance between the yarn comb hole 5501 and the tongue needle 2204 can be changed, thereby adjusting the length of the yarn and achieving a preliminary adjustment of the yarn tension. Furthermore, under the action of the ratchet 5402, the adjustable comb section 5 will not rotate downward, ensuring the stability of the yarn when the water jet loom is working.

[0034] The yarn wheel frame 4 set on the top of the support module 1 can ensure that the roller 43 is stably installed in any position, and with the cooperation of the adjustable comb section 5, the yarn can be smoothly guided to the latch needle 2204 on the needle bed 2 for spinning in any position.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
