Description

Technical Field

[0001] This invention belongs to the field of textile yarn tension adjustment technology, specifically a yarn tension stabilization and control device for water jet and air jet looms. Background Technology

[0002] Water jet looms and air jet looms are the mainstream shuttleless weaving equipment in the textile industry. With their advantages of high-speed weaving and high production efficiency, they are widely used in the production and processing of various chemical fiber, cotton, and blended fabrics. During the high-speed weaving operation of the loom, the stability of yarn tension, yarn cleanliness, and fabric winding regularity are the core factors that determine the quality of the finished fabric.

[0003] Traditional looms are mostly equipped with fixed tension control structures, which cannot adaptively adjust the tension according to the real-time yarn movement. Under the influence of factors such as yarn thickness differences, equipment vibration, and high-speed yarn pulling, the yarn tension is prone to fluctuating and uneven distribution. Traditional equipment lacks a targeted yarn cleaning structure, and a large amount of fly shavings, lint, dust, and weaving debris will adhere to the yarn during the conveying process. These impurities adhere to the yarn surface and participate in weaving, which can easily cause problems such as dirt spots and uneven texture on the fabric surface, further affecting the smoothness and quality of the finished fabric. In addition, traditional take-up rollers mostly use manual disassembly and assembly limiting structures, and manual disassembly and replacement of the roll is required after the fabric is wound up.

[0015] The beneficial effects of this invention are:

[0016] 1. This invention uses a vertical sliding adjustment structure of tension roller in conjunction with a tension sensor for real-time detection. It can adaptively fine-tune the yarn tension according to the running state of yarns of different materials and thicknesses, effectively solving the problems of excessive looseness, excessive tightness, and uneven tension fluctuation during yarn weaving.

[0017] 2.

Combined with a multi-dimensional elastic buffer structure, it can adapt to changes in the take-up roller diameter and flexibly adapt to the winding requirements of different types of fabrics. This effectively avoids fabric stretching, wrinkling, and edge curling deformation, ensuring a flat and tight winding. At the same time, through the guidance of the irregular track groove and the linkage unlocking structure, the limit fixation of the take-up roller can be automatically released after the fabric is wound, eliminating the need for manual disassembly and roll replacement.

[0031] 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.

[0032] Please see Figure 1-9As shown, this invention is a yarn tension stabilization and control device for a water-jet and air-jet loom, comprising two symmetrically arranged frame plates 1. The lower end of each frame plate 1 is provided with a clamping plate 10 mounted on the loom. Side frames 11 are fixedly installed on the adjacent sides of both frame plates 1. Multiple guide rollers 2 and tension rollers 20 for adjusting yarn tension are provided between the side frames 11. Adjustment grooves 12 are provided on both sides of the tension rollers 20 and are formed on the side frames 11. I-shaped blocks 14 are slidably installed in the middle of the adjustment grooves 12. The tension roller 20 is rotatably connected to the I-shaped block 14. A side rod 13 is fixedly installed on one side of the frame plate 1, and the corresponding side rod 13 slides outside it. The middle of the tension roller 20 is provided with a cleaning part that performs grooving and air jetting on multiple yarns during the threading process. The tension roller 20 is provided with a tension sensor. The tension sensor adaptively controls the tension roller 20 to lift and lower according to the real-time tension of the yarn on the tension roller 20. A winding module is also provided on one side of the frame plate 1 to wind up the fabric formed after the weft winding of the loom yarn is pressed.

[0033] When using this device, fix it to a water-jet or air-jet loom, and ensure that the yarn runs on the tension roller 20 and the guide roller 2. Figure 1 As shown, it should be noted that after the yarn passes the guide roller 2 closest to the rotating roller 40, it moves downward. The weaving of the fabric is done by the loom, which is the existing technology and will not be described in detail. When the yarn is running, if the tension sensor on the tension roller 20 detects that the yarn is too loose or too tight, it will drive the tension roller 20 to move up and down accordingly, so as to keep the yarn at a stable tension.

[0034] When the yarn is being threaded, to assist in the stable threading of the yarn, the motor is turned on to drive the rotating shaft 34 to rotate. When the rotating shaft 34 rotates, it drives the cam 35 to rotate. When the cam 35 rotates, it intermittently squeezes the arc plate 32. After the arc plate 32 is squeezed, it drives the piston rod 31 to compress inside the air cylinder 3. After the air cylinder 3 is compressed by the piston rod 31, the air inside the air cylinder 3 is blown into the air chamber 201. Since the tension roller 20 and the air pipe 30 are rotatably connected, the rotation of the tension roller 20 does not affect the air pipe 30's delivery of gas to the tension roller 20. When the air pipe 30 delivers gas into the tension roller 20, the gas inside the tension roller 20 is blown into the air chamber 201. The gas in the air chamber 201 is blown into the cleaning chute 204 through the circumferential groove 203. Finally, the cleaning chute 204 arranged on both sides of the yarn groove 202 blows the gas to the yarn passing through the yarn groove 202, thereby cleaning the yarn during threading.

[0035] When the rotating shaft 34 cleans the yarn on the tension roller 20, the rotating shaft 34 can also drive the extension rod 52 through the belt pulley mechanism. When the extension rod 52 rotates, it drives the gear 5 to rotate. Then, the gear 5 meshes with the gears 51 on both sides, causing the rotating rollers 40 on both sides to rotate in the same direction. The rotating rollers 40 on both sides rotate in the same direction, driving the take-up roller 41 to rotate, thereby taking up and winding the woven fabric. Compared with the existing device, the present invention can stabilize and control the tension of the yarn during the yarn threading process, clean the yarn, and also realize the winding of the fabric after the yarn is woven into fabric.

[0036] When the loom weaves yarn into fabric, this device is used to stably control the tension of the yarn as it runs. After the fabric is woven into fabric, the fabric is manually wound around the take-up roller 41 a certain number of times. Under the action of the springs on the guide rods 451 on both sides, the take-up roller 41 can be driven to abut between the two rotating rollers 40. When the rotating rollers 40 on both sides rotate in the same direction, they can generate friction on the fabric wound outside the take-up roller 41, thereby enabling the take-up roller 41 to rotate in the opposite direction to the rotating rollers 40, so that the fabric can be continuously wound around the take-up roller 41.

[0037] After the fabric is wound on the take-up roller 41, the electric slider opens, causing the hollow plate 47 to move away from the tension roller 20 on the drive frame 46. As the hollow plate 47 moves, it simultaneously moves the vertical rod 453, thereby moving the connecting block 45 and the take-up roller 41. Because the connecting block 45... During movement, the outer frame 484 drives the roller 483 to move within the track groove 482. When the roller 483 moves from the straight plate 48 to the inclined plate 481 area, the connecting block 45 moves away from the take-up roller 41. As the connecting block 45 moves away from the take-up roller 41, it simultaneously drives the inner cylinder 44 to move. The elastic force of the inner cylinder 44 on the spring inside it will reduce the pressure. At the same time, the snap-fit ​​43 will also move away from the end of the take-up roller 41 along with the inner cylinder 44, thereby eliminating the fixation of the take-up roller 41. Compared with the existing device, this invention can simultaneously drive the take-up roller 41 to wind the woven fabric while adjusting the tension of the yarn. After the take-up roller 41 has finished winding the fabric, there is no need for manual removal of the take-up roller 41 from the device.

[0038] The tension roller 20 is slidably mounted on both sides of the side frame 11 inside the adjustment groove 12 via I-shaped blocks 14. With the real-time detection signal of the tension sensor, the tension roller 20 can be driven to rise and fall vertically and precisely along the adjustment groove 12. Compared with the fixed tension roller structure, this structure can finely adjust the yarn tension stroke in real time according to the tension difference of yarns of different thicknesses and materials. It is suitable for the processing needs of various loom yarns such as cotton yarn, polyester yarn, and blended yarn, greatly improving the universality and adaptability of the device. At the same time, the vertical sliding limit structure ensures that the tension roller 20 does not deviate during the rising and falling process, avoiding yarn deviation and skipping problems.

[0039] The I-shaped block 14 is slidably sleeved on the outside of the fixed side rod 13 of the frame plate 1. The side rod 13 can rigidly guide and constrain the sliding trajectory of the I-shaped block 14 and the overall tension roller 20. This effectively prevents the tension roller 20 from horizontally shifting or swaying under yarn pulling and equipment vibration conditions, eliminates uneven tension of single yarns and local yarn slack or tightness deviations caused by roller body shift, ensures synchronous threading and tension control of multiple yarns, and improves the smoothness of fabric weaving.

[0040] The cleaning section includes an air cavity 201 located in the middle of the tension roller 20 and coaxially arranged with the tension roller 20. Multiple equally spaced grooves 202 are provided on the outside of the tension roller 20. On both sides of the grooves 202, circumferential grooves 203 are symmetrically arranged in the inner cavity of the tension roller 20 and connected to the air cavity 201. Multiple cleaning sloping grooves 204 are provided on the two side walls of the circumferential grooves 203 along the axis of the air cavity 201 to clean the yarn by blowing air when it runs in the grooves 202.

[0041] An air chamber 201 is coaxially arranged inside the tension roller 20, and an circumferential groove 203 and a cleaning inclined groove 204 are independently matched to each external yarn groove 202, forming a groove-by-groove cleaning structure. The compressed airflow from the air cylinder 3 is introduced into the air chamber 201 through the air pipe 30, and can individually and directionally clean the yarn passing through each yarn groove 202, specifically removing fly filth, cotton fibers, dust, and weaving debris from the yarn surface. Compared with an integral blowing structure, it can completely avoid the cross-adhesion of debris during the cleaning process of multiple yarns, while not affecting the normal threading of adjacent yarns, effectively improving the smoothness and weaving quality of the finished fabric.

[0042] The cleaning unit also includes an air cylinder 3 connected to the side away from the I-shaped block 14. One end of the air cylinder 3 is fixedly installed with an air pipe 30 that passes through and slides on the side of the tension roller 20. A piston rod 31 is slidably installed in the middle of the side of the air cylinder 3 away from the air pipe 30. An arc plate 32 is fixedly installed in one end of the piston rod 31. A spring is sleeved on the outside of the piston rod 31. A fixing plate 33 fixed to the side frame 11 is provided on one side of the piston rod 31. A rotating shaft 34 is rotatably installed in the middle of the fixing plate 33 by a motor. A cam 35 that abuts against the arc plate 32 is fixedly installed in one end of the rotating shaft 34.

[0043] The motor-driven rotating shaft 34 drives the cam 35 to intermittently press the arc plate 32. Combined with the resetting action of the external spring of the piston rod 31, the air cylinder 3 periodically draws in and exhausts air, forming an intermittent jet cleaning mode. Continuous constant-pressure jetting can easily cause wear, fuzzing, and breakage of fine yarns. However, this intermittent jetting structure can reduce the continuous impact of airflow on the yarn while ensuring dust removal effect, thus protecting the integrity of the yarn. At the same time, the intermittent working mode significantly reduces air circuit energy consumption and equipment operating noise, improving the overall working stability of the loom.

[0044] The rotating shaft 34 is linked to the extension rod 52 via a pulley mechanism, allowing a single motor to simultaneously drive two sets of mechanisms: on one hand, it drives the cam 35 to rotate, achieving yarn separation and air-jet cleaning; on the other hand, it drives gear 5 and gear 51 to mesh and drive the two sets of rollers 40 to rotate in the same direction, achieving fabric winding. This linkage structure eliminates the need for an additional winding drive motor, simplifying the equipment's power components, reducing the overall size of the device, assembly difficulty, and manufacturing costs, while ensuring that the cleaning and winding processes operate synchronously and collaboratively, achieving integrated weaving, cleaning, and winding operations.

[0045] The winding module includes a vertical plate 4 installed on one side of the frame plate 1. A straight plate 48 is fixedly installed on the top of the vertical plate 4. An inclined plate 481 is fixedly installed on the end of the straight plate 48 away from the vertical plate 4. The sides of the inclined plates 481 away from the straight plate 48 are far apart from each other. A track groove 482 with a similar external shape is opened in the middle of the straight plate 48 and the inclined plate 481. A roller 483 is slidably installed in the middle of the track groove 482. An external frame 484 is rotatably arranged on the outside of the roller 483. A connecting block 45 is fixedly installed on the side of the external frames 484 that are close to each other.

[0046] The winding module includes two symmetrically arranged rotating rollers 40 and a take-up roller 41 that contacts the gap between the two rotating rollers 40. Support plates 401 are provided on both sides of the two rotating rollers 40. The rotating rollers 40 are rotatably connected to the support plates 401. A connecting plate 402 is provided on the side of the support plates 401 that is far away from each other, and the corresponding side of the frame plate 1 is fixed thereto.

[0047] Two sets of symmetrical rotating rollers 40 rotate in the same direction, relying on friction to drive the take-up roller 41, which is in the middle, to rotate in the opposite direction to take in the fabric. With the elastic pressing action of the external spring of the guide rod 451, the take-up roller 41 can always maintain a flexible fit with the rotating rollers 40. Compared with the rigid take-up method that directly drives the take-up roller with a motor, this friction transmission structure can adapt to the change of the take-up roller 41's roll diameter and automatically adapt to the take-up speed and tension. This avoids the stretching, wrinkling, and curling deformation problems of hard and thin fabrics due to rigid pulling, ensuring that the fabric is rolled flat, tight, and uniform.

[0048] An extension rod 52 is rotatably mounted on one side support plate 401. A gear 5 is fixedly mounted on the extension rod 52. Two gears 51 mesh on both sides of the gear 5. The two gears 51 correspond to and are coaxially fixed with the two rotating rollers 40 respectively. The extension rod 52 and the rotating shaft 34 are driven by a belt pulley mechanism.

[0049] An inner cylinder 44 is fixedly installed on one side of the connecting block 45. A snap-fit ​​fitting 43 is provided on the outside of the inner cylinder 44 in a cross-shaped sliding engagement. A spring is connected between the snap-fit ​​fitting 43 and the inner cylinder 44. The snap-fit ​​fittings 43 on both sides respectively snap onto the two sides of the take-up roller 41. A vertical rod 453 is fixedly installed on the top of the connecting block 45. A moving assembly is provided on the outside of the vertical rod 453 to move the take-up roller 41 along the radial direction of the take-up roller 41.

[0050] The movable assembly includes a drive frame 46 fixedly mounted on one side of the straight plate 48. A hollow plate 47 is slidably mounted on the side of the drive frame 46 facing the vertical rod 453 via an electric slider. The vertical rod 453 is located in the middle of the hollow plate 47 and slides along the radial direction of the vertical rod 453.

[0051] A guide rod 451 is slidably nested in the middle of the connecting block 45. An end component 452 is fixedly installed on the top of the guide rod 451. A spring is sleeved on the outside of the guide rod 451 and abuts between the connecting block 45 and the end component 452. A guide rod 492 perpendicular to the axis of the guide rod 451 is slidably nested on the end component 452. A sleeve block 491 is fixedly installed on one end of the guide rod 492. A guide rod 49 perpendicular to the axis of the guide rod 492 is slidably nested in the middle of the sleeve block 491. A spring is sleeved on the outside of the guide rod 49. The guide rod 49 is fixedly connected to the top of the drive frame 46.

[0052] The irregularly shaped track groove 482, composed of the straight plate 48 and the inclined plate 481, combined with the sliding guide action of the roller 483 and the external frame 484, can convert the horizontal movement of the hollow plate 47 into the lateral separation displacement of the connecting block 45. This causes the inner cylinder 44 and the snap-fit ​​part 43 to automatically detach from the end of the take-up roller 41, automatically releasing the axial fixation, without the need for manual disassembly or insertion / removal of the limiting structure. This not only avoids the problems of roller collision and fabric damage that are easily caused by manual disassembly, but also significantly shortens the downtime for changing rolls and improves the efficiency of continuous production operations on the loom.

[0053] The device is equipped with multiple sets of vertically and horizontally interlaced elastic guide structures: guide rod 1 (451), guide rod 2 (49), and guide rod 3 (492) are each matched with corresponding springs to form a cross-shaped multi-directional buffer and limiting structure. This structure can provide all-around buffering and limiting of radial and lateral swaying during the operation of the take-up roller 41, counteracting equipment vibrations generated during high-speed weaving and take-up, preventing problems such as take-up roller 41 misalignment, fabric deviation, and uneven take-up, and significantly improving the operational stability of the equipment under high-speed weaving conditions.

[0054] The device uses tension roller 20 for real-time pressure stabilization and grooved cleaning to remove impurities during the yarn feeding stage. During the fabric forming stage, rotating roller 40 and take-up roller 41 smoothly wind up the fabric. These three processes work synchronously and independently. This addresses problems at their source, such as uneven fabric tension caused by unstable yarn tension, fabric defects caused by yarn impurities, and fabric deformation caused by unstable winding. It comprehensively improves the weaving yield and finished fabric quality of water-jet and air-jet looms. The clamping plate 10 at the bottom of the frame 1 uses a snap-fit ​​assembly structure, allowing for quick and easy mounting on various conventional water-jet and air-jet loom frames without the need for drilling or welding modifications to the machine body. Assembly is convenient and secure, and disassembly and maintenance are easy. It can be adapted to the upgrading of different loom models, significantly improving equipment adaptability and ease of maintenance.

[0055] The above description is merely an example and illustration of the concept of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the concept of the invention or exceed the scope defined in the claims, they should all fall within the protection scope of the present invention.
