Technical Field
[0001] This utility model belongs to the field of warp feeding mechanism for rapier looms, and specifically relates to a warp feeding mechanism for rapier looms. Background Technology
[0002] Rapier looms are the most widely used shuttleless looms. In addition to the characteristics of high speed, high automation and high efficiency of shuttleless looms, their active weft insertion method has strong adaptability to various types of yarns. Furthermore, rapier looms have obvious advantages in multi-color weft weaving, and can produce yarn-dyed products with up to 16 colors of weft yarn.
[0003] Existing technologies have specifically developed some warp feeding mechanisms for rapier looms. For example, Chinese Patent No. CN216712377U discloses "A warp feeding mechanism for a rapier loom," which helps to prevent warp threads from getting tangled. This utility model is convenient for limiting broken threads, preventing broken threads from getting tangled with other threads, and making it easy to adjust the tension of the threads.
[0004] Although the threaded sleeve moves to drive the lifting plate, which in turn moves the first guide wheel to adjust the tension of the warp, and the guide groove can restrict the broken warp on both sides when a warp breaks during operation, and the limiting tube can also restrict the broken warp on both sides to prevent the broken warp from getting tangled in other warp, the above structure cannot effectively disassemble the storage roller during use. This will result in a slow replacement frequency and reduced efficiency. Utility Model Content

[0017] refer to Figure 1 , Figures 2 to 3 Both sides of the placement groove 9 are fixedly installed with baffles 22. A limiting rod 18 is fixedly installed on the upper end of one side of the baffle 22, and a limiting post 12 is fixedly installed on the bottom end of one side of the baffle 22. The ends of the limiting rod 18 and the limiting post 12 away from the baffle 22 are fixedly installed inside the L-shaped frame 3. The upper end of the sliding rod 25 on both sides is provided with a limiting groove 27, and the bottom end of the sliding rod 25 is provided with a limiting groove 28. The sliding rod 25 on both sides is slidably installed on the outer ring of the limiting rod 18 and the limiting post 12 through the limiting groove 27 and the limiting groove 28. The placement groove 9 is equipped with a complete limiting and fixing system. The baffle 22, the limiting rod 18 and the limiting post 12 in the placement groove 9 constitute the limiting structure of the sliding rod 25. The limiting groove 27 at the upper end of the sliding rod 25 and the limiting groove 28 at the bottom end cooperate with the limiting rod 18 and the limiting post 12 respectively, limiting the movement range of the sliding rod 25 and preventing it from exceeding the safe range during movement, causing equipment damage or warp breakage.
[0018] refer to Figures 5 to 6 Square blocks 16 are fixedly installed on both sides of the handle 17. The square blocks 16 have slots 29 inside. Springs 30 are fixedly installed inside the slots 29. A locking block 31 is fixedly installed at the end of the springs 30 away from the slots 29. The base 6 has locking plates 10 fixedly installed on both sides of one end of the mounting groove 9. Each locking plate 10 has a locking groove 19 inside. The locking block 31 is engaged and installed inside the locking groove 19. When the sliding rod 25 is adjusted to the appropriate position, the locking block 31 is engaged into the locking groove 19 under the action of the spring 30, fixing the sliding rod 25 and ensuring that the yarn storage roller 2 remains stable during the operation of the loom and will not be displaced due to vibration or external force.
[0019] refer to Figures 3 to 5Multiple rollers 23 are rotatably installed on the inner ring of the support frame 24 on both sides. The two ends of the yarn storage roller 2 are rotatably installed on the outer ring of the rollers 23 inside the support frame 24. Guide grooves 26 are opened on both sides inside the placement groove 9. The guide rod 11 is slidably installed inside the guide groove 26 and is rotatably installed on the rollers 23 on the inner ring of the support frame 24. This design not only reduces the friction when the yarn storage roller 2 rotates, but also makes the yarn storage roller 2 rotate more flexibly to meet the needs of rapid warp yarn conveying. At the same time, the rotating plates 13 on both sides of the yarn storage roller 2 and the driving plates 21 on both sides of the upper end of the placement groove 9 cooperate with each other to provide power transmission for the conveying of warp yarn.
[0020] refer to Figures 2 to 3 Both sides of the rotating plates 13 away from the wire storage roller 2 are fixedly installed with docking blocks 14. The opposing surfaces of the driving plates 21 on both sides are provided with docking grooves 20. The docking blocks 14 are slidably installed inside the docking grooves 20. The output shaft of the drive motor 4 is fixedly installed on one side of one of the driving plates 21, which makes it convenient for staff to disassemble and replace the wire storage roller 2.
[0021] Operating principle and advantages: This warp feeding mechanism is based on base 6. A fixed plate 8 and a limiting plate 7 are fixedly installed on one side of the upper end of base 6, and a fixed frame 5 and a limiting roller 1 are on the other side, together forming the basic framework for warp yarn feeding. The fixed plate 8 and the limiting plate 7 are used for initial positioning and guidance of the warp yarns, while the limiting roller 1 on the fixed frame 5 further constrains the direction of the warp yarns, ensuring stability during feeding and preventing deviation or tangling. The placement groove 9 is the core active area of the warp feeding mechanism. The sliding rods 25 on both sides inside and their associated components are key to realizing warp yarn storage and adjustment. The sliding rods 25 can slide up and down within the placement groove 9, and the support frame 24 at their upper end supports the yarn storage roller 2. When it is necessary to adjust the warp yarn storage... When adjusting the quantity or tension, the operator can drive the protruding rod 15 through the handle 17, thereby moving the sliding rod 25 within the placement groove 9. The guide rods 11 on both sides of the protruding rod 15 cooperate with the guide grooves 26 on both sides of the placement groove 9, ensuring the stability and accuracy of the movement of the sliding rod 25 and preventing it from tilting or jamming during movement. The design of the yarn storage roller 2 is also quite ingenious. Its two ends are rotatably mounted through the rollers 23 on the inner ring of the support frame 24. This design not only reduces the friction when the yarn storage roller 2 rotates, but also allows the yarn storage roller 2 to rotate more flexibly, adapting to the needs of rapid warp yarn transport. At the same time, the rotating plates 13 on both sides of the yarn storage roller 2 cooperate with the driving plates 21 on both sides of the upper end of the placement groove 9 to provide power transmission for the transport of warp yarn. The drive motor 4, serving as the power source for the warp feeding mechanism, is installed on one side of the base 6. The motor output shaft is connected to the drive plate 21. When the motor starts, the drive plate 21 begins to rotate. The docking groove 20 inside the drive plate 21 cooperates with the docking block 14 on the rotating plate 13 of the yarn storage roller 2, transmitting the motor's power to the yarn storage roller 2. As the drive plate 21 rotates, the yarn storage roller 2 begins to rotate, thus achieving active warp feeding. This design ensures the stability and efficiency of power transmission, meeting the requirements for warp feeding speed and accuracy during high-speed operation of the rapier loom. To ensure the stability and safety of the warp feeding mechanism during operation, the mounting groove 9 is equipped with a complete limiting and fixing system, including baffles 22 and limiting rods within the mounting groove 9. The limiting rod 18 and the limiting post 12 constitute the limiting structure of the sliding rod 25. The limiting groove 27 at the upper end and the limiting groove 28 at the bottom end of the sliding rod 25 cooperate with the limiting rod 18 and the limiting post 12 respectively, limiting the movement range of the sliding rod 25 and preventing it from exceeding the safe range during movement, which could cause equipment damage or warp breakage. In addition, the locking blocks 31, springs 30 and square blocks 16 on both sides of the handle 17, together with the locking plate 10 and the locking groove 19 on the base 6, constitute the fixing device of the sliding rod 25. When the sliding rod 25 is adjusted to the appropriate position, the locking block 31 is locked into the locking groove 19 under the action of the spring 30, fixing the sliding rod 25 and ensuring that the yarn storage roller 2 remains stable during the operation of the loom and will not be displaced due to vibration or external force.
