Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to a weft-laying mechanism for a warp knitting machine. Background Technology

[0002] As the core component of a warp knitting machine, the weft laying mechanism mainly consists of a weft laying carriage, a beam guiding system, two side yarn locking and clamping devices, and a weft tension control and servo control system. Its working principle is that the weft laying carriage reciprocates along the machine's width under servo drive, evenly laying the weft yarn. When it reaches both ends, the yarn is fixed to the needle plate by the yarn pressing and clamping mechanism. Then, the needle plate feeds the weft yarn into the knitting area to form loops with the warp yarn. Through precise synchronous control, continuous weft laying with different angles, densities, and widths is achieved. The reversing accuracy, motion stability, and buffering effect of its reciprocating lateral movement directly affect the production quality of warp-knitted fabrics and the operating efficiency of the equipment. Currently, the reversing of the weft laying carriage in the weft laying mechanism of warp knitting machines mostly relies on the forward and reverse rotation of the drive motor in conjunction with a toothed belt.

[0003] However, the frequent start-stop and reversal of the motor and belt can easily generate mechanical shock and vibration, which not only reduces the motion accuracy of the weft laying carriage, but also accelerates the fatigue wear of the core drive components, shortens the service life of the equipment, and the delay in reversing start-stop will reduce production efficiency, thereby affecting the efficiency and quality of weft laying, and thus affecting the efficiency and quality of textile production. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This type of warp knitting machine's weft-laying mechanism, through the setting of two sets of clamping mechanisms, allows the weft-laying carriage to move back and forth on the guide rail during weft laying. In operation, the motor is started, driving the toothed pulley to rotate via the shaft, thus driving the toothed belt to convey the material. The clamping mechanisms then move the weft-laying carriage along the guide rail. When the weft-laying carriage moves to the right, the upper clamping mechanism clamps the upper part of the toothed belt; when the weft-laying carriage moves to the left, the upper clamping mechanism releases, and the lower clamping mechanism clamps the lower part of the toothed belt. During clamping, an electromagnet is energized, attracting an iron block, causing the toothed clamping plate to move closer to the fixed plate and clamp against the toothed belt. Simultaneously, the first spring... When the spring telescopic rod is compressed, the electromagnet is de-energized when it needs to be released. The toothed clamp plate can then move away from the fixed plate under the action of the first spring telescopic rod and disengage from the toothed belt. This allows for the clamping and fixing of the upper or lower part of the toothed belt independently, thereby enabling automatic reversing of the weft-laying carriage. The motor and toothed belt do not need to be reversed. This design ensures that the motor and toothed belt always operate continuously in one direction, avoiding the impact, vibration, and mechanical wear caused by frequent start-stop and forward / reverse switching. This not only improves the stability and accuracy of the reciprocating motion of the weft-laying carriage but also effectively extends the service life of core components such as the motor and toothed belt, reduces time loss during reversal, and improves the efficiency and quality of weft laying, thereby improving the efficiency and quality of textile production.

[0017] This type of warp knitting machine's weft-laying mechanism, through the inclusion of a trigger mechanism, causes the moving plate to move synchronously when the weft-laying carriage moves. When the weft-laying carriage moves to the right, the moving plate stops moving when the rubber block abuts against the right-side column. As the weft-laying carriage continues to move, it pushes a ball out of the second limiting hole and slides to the side wall of the moving plate. Simultaneously, the second spring telescopic rod is compressed, which in turn moves the guide block and the detection block. At this point, the movement is detected by the distance sensor, and the machine can then... De-energize the two upper electromagnets to disconnect the weft-laying carriage from the toothed belt, and use a buffer mechanism to cushion the weft-laying carriage. After the buffering is complete, the ball aligns with the first limiting hole. At this time, the ball can be inserted into the first limiting hole under the action of the second spring telescopic rod to limit the movement of the plate. At the same time, energize the two lower electromagnets to clamp the lower clamping mechanism with the lower part of the toothed belt, thereby driving the weft-laying carriage to move to the left, making the automatic reversal of the weft-laying carriage more convenient and faster.

[0018] This type of warp knitting machine's weft-laying mechanism, through the setting of auxiliary mechanisms, allows the rollers to roll on the side wall of the guide rail when the weft-laying carriage moves, which can assist in the movement and greatly reduce the resistance when the weft-laying carriage moves on the guide rail, making the movement smoother. Under the action of the second spring, the slider can always be pressed against the guide rail, effectively eliminating the gap between the slider and the guide rail, avoiding the weft-laying carriage from shaking, slipping, or jamming during high-speed reciprocating motion, and ensuring the accuracy of the weft-laying position and the quality of the fabric.

[0019] This warp knitting machine's weft-laying mechanism, through the inclusion of a buffer mechanism, allows the disc to move closer to the fixed tube when it abuts against the column after the clamping mechanism and toothed belt are released. Simultaneously, the first spring deforms, and the sliding disc slides within the fixed tube via the first connecting rod, allowing damping fluid to flow through the circular hole. This provides excellent buffering, preventing violent collisions of the weft-laying carriage. Furthermore, as the sliding disc moves, the second connecting rod pushes the moving block into the fixed cover, compressing the hydraulic oil within the fixed cover. This hydraulic oil then flows through the second connecting pipe, the first connecting pipe, and the U-shaped pipe into the sleeve. Under hydraulic pressure, the sleeve rod moves away from the sleeve, thereby moving the U-shaped frame and rollers. This increases the pressure between the rollers and the guide rail, resulting in greater friction and improved buffering, leading to smoother movement of the weft-laying carriage.

[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 Figures 1-10 This invention provides a weft-laying mechanism for a warp knitting machine, comprising a main body. The main body includes a column 101, a yarn-locking and joining module 102 connected to the column 101, a weft-laying carriage 104 connected to the column 101, and a lateral movement module for driving the weft-laying carriage 104 to reciprocate laterally. The lateral movement module includes a guide rail 103 connected to the column 101, a slider 105 connected to the weft-laying carriage 104, and a toothed belt 106 connected to the slider 105 for transmission. These are all well-known technologies in this field and will not be described in detail here. The main body also includes two sets of clamping mechanisms arranged vertically between the weft-laying carriage 104 and the toothed belt 106, and the two sets of clamping mechanisms are respectively used to clamp the toothed belt 106. The upper and lower parts are designed to achieve synchronous movement of the weft-laying carriage 104 and the toothed belt 106, and to realize the automatic reversal of the weft-laying carriage 104. By having two sets of clamping mechanisms alternately clamp the upper and lower parts of the toothed belt 106, the automatic reversal of the weft-laying carriage 104 can be achieved. This ensures that the motor 503 and the toothed belt 106 always maintain continuous unidirectional operation, avoiding the impact, vibration, and mechanical wear caused by frequent start-stop and forward / reverse switching. This not only improves the stability and accuracy of the reciprocating motion of the weft-laying carriage 104, but also effectively extends the service life of core components such as the motor 503 and the toothed belt 106, reduces the time loss during the reversal process, and improves the efficiency and quality of weft laying, thereby improving the efficiency and quality of textile production.

[0033] Each clamping mechanism includes two fixed plates 201 connected to the weft laying carriage 104, a toothed clamping plate 202 connected to the fixed plate 201, and a lifting mechanism connecting the toothed clamping plate 202 and the fixed plate 201. By moving the toothed clamping plate 202 through the lifting mechanism, the clamping and loosening with the toothed belt 106 can be achieved, which is more convenient and faster. In addition, the toothed clamping plate 202 and the toothed belt 106 are matched to improve the clamping and fixing effect.

[0034] The lifting mechanism includes an electromagnet 302 connected to the fixed plate 201, an iron block 303 connected to the toothed clamping plate 202, and a first spring telescopic rod 301 connected between the fixed plate 201 and the toothed clamping plate 202. When clamping, the electromagnet 302 is energized, which attracts the iron block 303, causing the toothed clamping plate 202 to move closer to the fixed plate 201 and clamp against the toothed belt 106. At the same time, the first spring telescopic rod 301 is compressed. When it is necessary to release, the electromagnet 302 is de-energized, and the toothed clamping plate 202 can move away from the fixed plate 201 under the action of the first spring telescopic rod 301 and disengage from the toothed belt 106. This allows the upper or lower part of the toothed belt 106 to be clamped and fixed independently, facilitating the lifting and lowering of the toothed clamping plate 202 and realizing clamping and releasing operations.

[0035] The lifting mechanism also includes a triggering mechanism mounted on the weft-laying trolley 104, which triggers the weft-laying trolley 104 to automatically change direction. The triggering mechanism includes a moving plate 401, rubber blocks 402 connected to both ends of the moving plate 401, and a moving mechanism connecting the moving plate 401 and the weft-laying trolley 104. The moving mechanism includes a fixed block 403 connected to the weft-laying trolley 104, a guide rod 404 connected to the fixed block 403, and a guide block 405 connected to the moving plate 401. The guide block 405 is sleeved on the side wall of the guide rod 404. The triggering mechanism also includes a mechanism for moving the guide block 405. The detection component for testing and the limiting component for limiting the movement plate 401 can drive the movement plate 401 to move synchronously when the weft laying carriage 104 moves. When the weft laying carriage 104 moves to the right, the movement plate 401 stops moving when the rubber block 402 abuts against the right-side column 101. When the weft laying carriage 104 continues to move, it can drive the guide block 405 to move and be detected by the detection component. Then, the two electromagnets 302 above can be de-energized, so that the weft laying carriage 104 is disconnected from the toothed belt 106, which facilitates the reversing operation of the weft laying carriage 104.

[0036] The detection assembly includes a distance sensor 601 connected to the fixed block 403 and a detection block 602 connected to the side wall of the guide block 405. When the weft-laying carriage 104 moves to the right, when the rubber block 402 abuts against the right-side column 101, the moving plate 401 stops moving. When the weft-laying carriage 104 continues to move, it can push the ball 705 out of the second limiting hole 702 and slide to the side wall of the moving plate 401. At the same time, the second spring telescopic rod 704 is compressed, which can drive the guide block 405 to move and drive the detection block 602 to move. At this time, it can be detected by the distance sensor 601, which is convenient for detection when the weft-laying carriage 104 moves to both sides.

[0037] The limiting assembly includes a first limiting hole 701 and a second limiting hole 702 formed on the side wall of the movable plate 401; the limiting assembly also includes a ball 705, a bracket 703 connected to the weft-laying trolley 104, and a second spring telescopic rod 704 connecting the ball 705 and the bracket 703; the ball 705 can slide into the first limiting hole 701 and the second limiting hole 702, and when the weft-laying trolley 104 moves to the right, when the rubber block 402 abuts against the right-side column 101, the ball 705 moves to the right. When the movable plate 401 stops moving, and the weft-laying carriage 104 continues to move, it can push the ball 705 out of the second limiting hole 702 and slide to the side wall of the movable plate 401. After the buffering is completed, the ball 705 is aligned with the first limiting hole 701. At this time, the ball 705 can be inserted into the first limiting hole 701 under the action of the second spring telescopic rod 704, thereby limiting the movable plate 401 and ensuring that the movable plate 401 will not move when the weft-laying carriage 104 moves normally.

[0038] The main body of the device also includes a buffer mechanism for buffering the weft-laying carriage 104; the buffer mechanism includes multiple fixed tubes 901 connected to the weft-laying carriage 104, a sliding disc 902 sliding within the fixed tubes 901, and multiple circular holes 903 opened at the ends of the sliding disc 902; the buffer mechanism also includes a disc 905, a first connecting rod 904 connecting the disc 905 and the sliding disc 902, and a first spring 906 connecting the disc 905 and the sliding disc 902; the first spring 906 is sleeved on the first connecting rod 905. The side wall of 04; the fixed tube 901 is filled with damping fluid. When the clamping mechanism is released from the toothed belt 106, when the disc 905 abuts against the column 101, it can push the disc 905 to move closer to the fixed tube 901. At the same time, the first spring 906 deforms. Meanwhile, the first connecting rod 904 drives the sliding disc 902 to slide in the fixed tube 901, so that the damping fluid can flow through the round hole 903, thereby achieving a good buffering effect and preventing the weft laying trolley 104 from being violently collided.

[0039] The main body of the device also includes an auxiliary mechanism for assisting the movement of the weft-laying trolley 104; the auxiliary mechanism includes a U-shaped frame 805, rollers 806 rotatably connected to the U-shaped frame 805, and a telescopic mechanism connecting the U-shaped frame 805 and the weft-laying trolley 104; the telescopic mechanism includes a fixed frame 801 connected to the weft-laying trolley 104, a sleeve 802 connected to the fixed frame 801, and a sleeve rod 803 connecting the sleeve 802 and the U-shaped frame 805; the sleeve rod 803 is inserted into the sleeve 802; the telescopic mechanism also includes a second spring 804 connecting the U-shaped frame 805 and the fixed frame 801; the second spring 804 is sleeved on the... The sleeve 802 has a side wall; the telescopic mechanism also includes a pushing mechanism for moving the sleeve rod 803. When the weft laying carriage 104 moves, the roller 806 rolls on the side wall of the guide rail 103, which can assist in the movement and greatly reduce the resistance when the weft laying carriage 104 moves on the guide rail 103, making the movement smoother. Under the action of the second spring 804, the slider 105 can always press against the guide rail 103, effectively eliminating the gap between the slider 105 and the guide rail 103, avoiding the weft laying carriage 104 from shaking, moving or jamming in high-speed reciprocating motion, and ensuring the accuracy of the weft laying position and the quality of the fabric.

[0040] The pushing mechanism includes a fixed cover 1003 connected to the weft-laying trolley 104, two movable blocks 1005 sliding within the fixed cover 1003, and a second connecting rod 1006 connecting the movable blocks 1005 and the sliding disk 902. The pushing mechanism also includes a U-shaped tube 1001 communicating with the sleeve 802, a first connecting pipe 1002 communicating with the U-shaped tube 1001, and a second connecting pipe 1004 connecting the first connecting pipe 1002 and the fixed cover 1003. The fixed cover 1003 is filled with hydraulic oil, which, when the sliding disk 902 moves, can push the movable blocks via the second connecting rod 1006. 1005 moves into the fixed cover 1003, thereby squeezing the hydraulic oil inside the fixed cover 1003 and allowing the hydraulic oil to enter the sleeve 802 through the second connecting pipe 1004, the first connecting pipe 1002 and the U-shaped pipe 1001. Under the action of hydraulic pressure, the sleeve rod 803 is pushed to move away from the sleeve 802, thereby driving the U-shaped frame 805 and the roller 806 to move, which increases the squeezing force between the roller 806 and the guide rail 103, and makes the friction between the roller 806 and the guide rail 103 greater, which can improve the buffering effect and make the movement of the weft laying trolley 104 more stable.

[0041] The main body of the device also includes a conveying mechanism for conveying the toothed belt 106; the conveying mechanism includes two toothed pulleys 502, a rotating shaft 501 connected between the toothed pulleys 502 and the column 101, and a motor 503 for driving the rotating shaft 501 to rotate; the motor 503 is fixed to the column 101. When the motor 503 is started, the toothed pulleys 502 are driven to rotate through the rotating shaft 501, thereby driving the toothed belt 106 to be conveyed, and then the weft laying trolley 104 is driven to move along the guide rail 103 through the clamping mechanism.

[0042] Working principle: During operation, the weft-laying carriage 104 moves back and forth on the guide rail 103. When in use, the motor 503 is started, which drives the toothed pulley 502 to rotate through the rotating shaft 501, thereby driving the toothed belt 106 to convey the material. Then, the clamping mechanism drives the weft-laying carriage 104 to move along the guide rail 103. When the weft-laying carriage 104 moves to the right, the upper clamping mechanism clamps the upper part of the toothed belt 106. When the weft-laying carriage 104 moves to the left, the upper clamping mechanism releases, and the lower clamping mechanism clamps the lower part of the toothed belt 106.

[0043] During clamping, the electromagnet 302 is energized, attracting the iron block 303. This causes the toothed clamp 202 to move closer to the fixed plate 201 and clamp against the toothed belt 106. Simultaneously, the first spring telescopic rod 301 is compressed. When release is needed, the electromagnet 302 is de-energized, allowing the toothed clamp 202 to move away from the fixed plate 201 under the action of the first spring telescopic rod 301 and disengage from the toothed belt 106. This allows for clamping and fixing of either the upper or lower part of the toothed belt 106 independently. The automatic reversing of the weft-laying carriage 104 is achieved, while the motor 503 and toothed belt 106 do not need to be reversed. This design ensures that the motor 503 and toothed belt 106 always maintain continuous unidirectional operation, avoiding the impact, vibration, and mechanical wear caused by frequent start-stop and forward / reverse switching. This not only improves the stability and accuracy of the reciprocating motion of the weft-laying carriage 104, but also effectively extends the service life of core components such as the motor 503 and toothed belt 106, reduces time loss during the reversing process, and improves the efficiency and quality of weft laying, thereby improving the efficiency and quality of textile production.

[0044] When the weft-laying carriage 104 moves, the roller 806 rolls on the side wall of the guide rail 103, which can assist the movement and greatly reduce the resistance when the weft-laying carriage 104 moves on the guide rail 103, making the movement smoother. Under the action of the second spring 804, the slider 105 can always press against the guide rail 103, effectively eliminating the gap between the slider 105 and the guide rail 103, avoiding the weft-laying carriage 104 from shaking, swaying or jamming during high-speed reciprocating motion, and ensuring the accuracy of the weft-laying position and the quality of the fabric.

[0045] When the weft-laying carriage 104 moves, it can drive the moving plate 401 to move synchronously. When the weft-laying carriage 104 moves to the right, when the rubber block 402 abuts against the right-side column 101, the moving plate 401 stops moving. When the weft-laying carriage 104 continues to move, it can push the ball 705 out of the second limiting hole 702 and slide to the side wall of the moving plate 401. At the same time, the second spring telescopic rod 704 is compressed. Meanwhile, it can drive the guide block 405 to move and drive the detection block 602 to move. At this time, it can be detected by the distance sensor 601. At this time, the two electromagnets 302 above can be de-energized, so that the weft-laying carriage 104 is disconnected from the toothed belt 106, and the buffer mechanism is used to buffer the weft-laying carriage 104.

[0046] When the clamping mechanism is released from the toothed belt 106, and the disc 905 abuts against the column 101, it can push the disc 905 to move closer to the fixed tube 901. At the same time, the first spring 906 deforms, and at the same time, the sliding disc 902 is driven to slide in the fixed tube 901 through the first connecting rod 904, so that the damping fluid can flow through the round hole 903, thereby achieving a good buffering effect and preventing the weft laying carriage 104 from being violently collided.

[0047] Furthermore, when the sliding disc 902 moves, it can push the moving block 1005 into the fixed cover 1003 through the second connecting rod 1006, thereby squeezing the hydraulic oil in the fixed cover 1003 and allowing the hydraulic oil to enter the sleeve 802 through the second connecting pipe 1004, the first connecting pipe 1002 and the U-shaped pipe 1001. Under the action of hydraulic pressure, the sleeve rod 803 is pushed to move away from the sleeve 802, thereby driving the U-shaped frame 805 and the roller 806 to move, which increases the squeezing force between the roller 806 and the guide rail 103, and makes the friction between the roller 806 and the guide rail 103 greater, which can improve the buffering effect and make the movement of the weft laying trolley 104 more stable.

[0048] After the buffering is completed, the ball 705 is aligned with the first limiting hole 701. At this time, the ball 705 can be inserted into the first limiting hole 701 under the action of the second spring telescopic rod 704 to limit the movement plate 401. At the same time, the two electromagnets 302 below are energized, so that the clamping mechanism below clamps the lower part of the toothed belt 106, thereby driving the weft laying carriage 104 to move to the left, making the automatic reversal of the weft laying carriage 104 more convenient and faster.
