Description

Technical Field

[0001] This utility model relates to the field of wire breakage detection wiring production and processing technology, and in particular to a wire breakage detection wiring device for single yarn conveying. Background Technology

[0002] In the yarn processing of textiles, knitting and other fields, yarn breakage detection and connection devices are key equipment to ensure continuous production. Their main function is to achieve stable yarn transport and to quickly detect and handle yarn breakage in a timely manner to reduce production interruptions caused by yarn breakage.

[0003] However, the transmission system of traditional yarn conveying equipment often suffers wear and loosening due to long-term operation of the synchronous belt, resulting in inconsistent roller speeds, affecting the stability of yarn conveying tension, and requiring frequent manual shutdowns for adjustment, which increases maintenance costs and production downtime. At the same time, the traction roller assembly is prone to jamming due to radial force when the yarn deviates, which aggravates yarn wear and may even cause secondary yarn breakage, further reducing production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wire breakage detection wiring device for single yarn conveying, which aims to improve the problems of asynchronous transmission, long manual adjustment and maintenance time, and easy wire breakage in traditional equipment.

[0006] The above technical solution involves releasing the yarn from the unwinding spool, aligning and gathering it through a trumpet-shaped opening, guiding it through a guide roller, and then guiding it between the upper and lower rollers. A first motor drives the transmission shaft to rotate, which in turn drives the synchronous pulley and belt, enabling multiple rollers to rotate synchronously. The upper and lower rollers adjust their clamping force on the yarn through sliding, using friction to stabilize the yarn transport. The synchronous belt and pulley work together to ensure consistent roller speeds, preventing uneven yarn stretching or breakage due to speed differences.

[0009] Preferably, multiple drive shafts are rotatably connected to the inner wall of the base, the upper roller is installed at the output end of the drive shaft, and the upper roller and the lower roller are slidably connected to each other.

[0010] Preferably, the wiring assembly includes a third motor, which is disposed inside the base. The output end of the third motor is equipped with a threaded rod, and the outer wall of the threaded rod is threadedly connected to a detection module. The detection module is equipped with a cylinder, and one end of the cylinder is equipped with a laser welding module.

[0011] Preferably, the lead screw rotates on the inner wall of the base, and the inner wall of the base is provided with multiple sliding grooves, through which the sliding plate is slidably connected to the inner wall of the base.

[0012] Preferably, the slider is slidably connected inside the base, the limiting rod is installed inside the base, and the spring is sleeved on the outer wall of the limiting rod.

[0013] Preferably, the threaded rod is rotatably connected to the inner wall of the base, the detection module is slidably connected to the inner wall of the base through a limiting groove, and the cylinder is slidably connected to the inner wall of the detection module.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the stable conveying of yarn is achieved through the cooperation of the first motor, the transmission shaft and the synchronous belt pulley, etc. The small-range swing of the roller group is adjusted to counteract the radial force of the yarn deviation, avoid roller jamming to ensure smooth conveying, and automatically compensate for the slack of the synchronous belt caused by wear and temperature changes.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0026] Reference Figures 1-3This utility model provides an embodiment of a single yarn conveying wire breakage detection and wiring device, comprising a base 1, with multiple unwinding reels 2, a bell mouth 3, and guide rollers 4 installed on the inner wall of the base 1, a first motor 5 disposed inside the base 1, a drive shaft 6 installed at the output end of the first motor 5, a self-aligning ball bearing 9 and a synchronous pulley 10 installed on the outer wall of the drive shaft 6, multiple sets of rollers disposed on the inner wall of the base 1, the rollers including upper rollers 7 and lower rollers 8, a synchronous belt 11 meshing with the toothed ends of the outer walls of the multiple synchronous pulleys 10, an adaptive component disposed on the outer wall of the synchronous belt 11, and a wiring component disposed on the inner wall of the base 1; multiple drive shafts 6 are rotatably connected to the inner wall of the base 1, the upper rollers 7 are installed at the output end of the drive shafts 6, and the upper rollers 7 and lower rollers 8 are slidably connected to each other.

[0027] Specifically, during operation, the yarn is first released from the unwinding spool 2. It then passes through the bell-shaped opening 3 to neatly gather the loose yarn, preventing tangling and knots. Next, the tension is initially adjusted by the guide roller 4, ensuring the yarn remains straight as it enters between the upper roller 7 and the lower roller 8. The first motor 5 is then started, driving the transmission shaft 6 through its output end. This drives one of the synchronous pulleys 10 to rotate, which in turn drives the synchronous belt 11 through toothed engagement. This causes multiple synchronous pulleys 10 to rotate synchronously on the inner wall of the synchronous belt 11, thereby driving multiple sets of rollers to rotate synchronously. The upper roller 7 and the lower roller 8 adjust the clamping force by sliding against each other, and use friction to drive the yarn forward stably. The synchronous belt 11 and the synchronous pulley 10 work together to ensure that the speed of multiple rollers is consistent, effectively avoiding uneven yarn stretching or breakage caused by roller speed differences. The self-aligning ball bearing 9 allows the drive shaft 6 and roller group to swing within a small range, thereby counteracting the radial force caused by slight deviation during yarn conveying, preventing roller group jamming and yarn wear, improving the stability of equipment operation, reducing the incidence of conveying failure, and improving production efficiency.

[0028] Reference Figure 1 , Figure 5 and Figure 6The wiring assembly includes multiple second motors 16, which are installed inside the base 1. A lead screw 17 is installed at the output end of each second motor 16, and multiple sliding plates 18 are threadedly connected to the outer wall of the lead screw 17. These sliding plates 18 are slidably connected to each other. The wiring assembly also includes a third motor 19, which is located inside the base 1. A threaded rod 20 is installed at the output end of the third motor 19, and a detection module 21 is threadedly connected to the outer wall of the threaded rod 20. A cylinder 22 is installed inside the detection module 21, and a laser welding module 23 is installed at one end of the cylinder 22. The lead screw 17 rotates on the inner wall of the base 1, and multiple sliding grooves are provided on the inner wall of the base 1. The sliding plates 18 are slidably connected to the inner wall of the base 1 through these grooves. The threaded rod 20 is rotatably connected to the inner wall of the base 1, the detection module 21 is slidably connected to the inner wall of the base 1 through a limiting groove, and the cylinder 22 is slidably connected to the inner wall of the detection module 21.

[0029] Specifically, during equipment operation, the third motor 19 drives the threaded rod 20 to rotate, causing the detection module 21 to slide on the inner wall of the base 1 to detect the yarn. This is achieved through the cooperation of a photoelectric sensor and a tension sensor. When the detection module 21 detects a yarn break, the system immediately triggers an emergency brake, activating the second motor 16 to drive the lead screw 17 to rotate. This guides the sliding plates 18 through the grooves of the base 1, causing multiple sliding plates 18 to approach each other and slide smoothly along the grooves, precisely squeezing and fixing the broken ends to prevent the broken yarn from shifting during welding. Then, the third motor 19 drives the threaded rod 20 to rotate, causing the detection module 21 to move within the limiting groove. Under the guidance and restriction, the laser welding module slides on the outer wall of the threaded rod 20 until it is directly above the broken wire, ensuring that the detection and welding positions are accurately aligned. After the fixing and positioning are completed, the cylinder 22 in the detection module 21 pushes the laser welding module 23 close to the broken wire end to perform the welding operation. Through the smooth connection of each component drive, the fixing, position adjustment and welding operations of the broken wire are automated. The wiring can be completed without manual intervention, shortening the wiring time and reducing labor intensity. It effectively improves the reliability of the broken wire fixing and the accuracy of the welding position, and ultimately ensures stable wiring quality, avoiding problems such as irregular joints and insufficient strength in traditional manual wiring. Example

[0030] Reference Figure 4 This embodiment is based on the description of Embodiment 1. When the timing belt 11 is loose after working for a long time, this embodiment improves on this. The adaptive component includes a tensioning wheel 12, which abuts against the outer wall of the timing belt 11. A slider 13 is installed on the outer wall of the tensioning wheel 12. A limit rod 14 is slidably connected to the inner wall of the slider 13. A spring 15 is provided on one side of the slider 13.

[0031] Specifically, under the elastic force of spring 15, the tensioning wheel 12 is always tightly pressed against the outer wall of the synchronous belt 11 by slider 13, providing stable tension for the synchronous belt 11 and ensuring no slippage between the synchronous pulley 10 and the synchronous belt 11, thereby ensuring the synchronous transmission accuracy of multiple rollers. When the synchronous belt 11 becomes worn, stretched, or loosened due to thermal expansion and contraction caused by long-term operation, spring 15 will push slider 13 to slide along limit rod 14 towards the synchronous belt 11, so that tensioning wheel 12 is always pressed against the outer wall of synchronous belt 11, automatically compensating for the looseness of synchronous belt 11 and maintaining stable tension. If the synchronous belt 11 tightens temporarily, tensioning wheel 12 will be simultaneously pressed against the outer wall of synchronous belt 11. The stepping belt 11 pushes the slider 13 along the limiting rod 14 to compress the spring 15. The spring 15's buffering effect prevents the synchronous belt 11 from breaking due to a sudden increase in tension. The limiting rod 14 provides precise guidance for the sliding direction of the slider 13, preventing the synchronous belt 11 from becoming unevenly worn or losing tension due to the misalignment of the slider 13 and the tensioning wheel 12. Frequent manual stops for adjustment are unnecessary. Through the adaptive elasticity of the spring 15 and the guiding action of the limiting rod 14, real-time automatic compensation of the synchronous belt 11 tension is achieved. This ensures the stability and reliability of synchronous transmission, reduces uneven yarn feeding and yarn breakage caused by the slack of the synchronous belt 11, lowers manual maintenance costs, and improves the continuous operation capability of the equipment.

[0032] Reference Figure 4 The slider 13 is slidably connected inside the base 1, the limiting rod 14 is installed inside the base 1, and the spring 15 is sleeved on the outer wall of the limiting rod 14.

[0033] Specifically, the base 1 ensures that the slider 13 can move smoothly along the preset trajectory of the base 1. The limiting rod 14 cooperates to provide stable support and guidance for the slider 13 and the spring 15. The spring 15 is sleeved on the outer wall of the limiting rod 14, with one end abutting against the outer wall of the slider 13 and the other end fixed to the inner wall of the base 1, forming a complete elastic drive and guiding system. The double guidance prevents the slider 13 from tilting and getting stuck during the sliding process, avoids the spring 15 from twisting and shifting when it extends and retracts, and ensures that the elastic force output is uniform and stable.

[0034] Working Principle: When this utility model is in operation, the yarn is drawn out from the unwinding spool 2 on the inner wall of the base 1, guided and regulated by the trumpet mouth 3, combed and pre-tensioned by the guide wheel 4, and then enters the traction mechanism composed of the upper roller 7 and the lower roller 8. The first motor 5 is started to drive the synchronous belt pulley 10 to rotate through the transmission shaft 6. The synchronous belt 11 is driven by the synchronous belt pulley 10 to rotate, realizing the synchronous transmission of multiple rollers. Then, the stable conveying of the yarn is completed by the pressure friction between the upper roller 7 and the lower roller 8. When the transmission shaft 6 rotates, the self-aligning ball bearing 9 on its outer wall adjusts the multiple roller groups to swing within a small range, which can counteract the radial force caused by yarn deviation and prevent roller jamming. When the synchronous belt 11 is loose for a long time, the elastic support of the slider 13 by the spring 15 pushes the tensioning wheel 12 to always press against the synchronous belt 11. This can automatically compensate for the looseness of the synchronous belt 11 caused by wear and temperature changes, eliminating the need for frequent manual adjustment, thereby improving the stability of the transmission and the continuous operation capability of the equipment.

[0035] With the cooperation of photoelectric sensors and tension sensors, the third motor 19 drives the threaded rod 20 to slide the detection module 21 against the inner wall of the base 1 to detect the yarn. Once a yarn break is detected, the system immediately triggers an emergency brake to stop the first motor 5. At the same time, the second motor 16 drives the lead screw 17 to rotate, causing multiple slide plates 18 to slide along the grooves of the base 1 to the nearest side, squeezing and fixing the broken yarn. The third motor 19 adjusts the lateral position of the detection module 21 through the threaded rod 20. After positioning, the cylinder 22 inside the detection module 21 pushes the laser welding module 23 close to the yarn break. The laser welding module 23 uses a focused fiber laser to melt and weld the yarn break. Nitrogen protection during the welding process prevents yarn oxidation, and the dynamic calibration mechanism of the laser head can adjust the focal length in real time according to the yarn diameter fluctuation to ensure welding quality. The entire process from yarn break detection to welding is fully automated, shortening manual wiring time, reducing labor intensity, and avoiding the joint protrusion problem of traditional wiring methods, thus improving the continuity of yarn feeding and the quality of finished products.
