Technical Field
[0001] This utility model relates to the field of loom technology, and in particular to an anti-tangle yarn guiding device for looms. Background Technology
[0002] An anti-tangle yarn guide device for looms is an auxiliary device installed on a loom. Its function is to guide the weft yarn to pass smoothly through the warp yarn and prevent the yarn from tangling or breaking during high-speed operation, thereby improving weaving efficiency and fabric quality.
[0003] Anti-tangle yarn guiding devices for looms typically include components such as yarn guide rods, yarn guide plates, yarn guide rings, tension devices, cleaning devices, and possibly high-speed rotating yarn guide wheels. These components work together to ensure that the yarn maintains appropriate tension, cleanliness, and guidance during the weaving process, avoiding tangling and yarn breakage problems.
[0004] However, the following problems were found in the implementation of the relevant technology: After long-term use, the yarn guide ring will have a reduced yarn guiding effect due to wear, deformation or accumulation of dirt. Therefore, it needs to be inspected and replaced regularly to maintain the normal operation of the loom and the quality of the fabric. However, the yarn guide ring is generally fixed by screws, and replacing the yarn guide ring requires stopping the entire machine. Therefore, it may take a lot of time to remove and replace the yarn guide ring. In view of this, an anti-tangle yarn guide device for looms is provided to overcome the above defects.

[0013] This utility model has the following beneficial effects:
[0014] This utility model designs an anti-tangle yarn guiding device for looms. Through design and coordination, it combines components such as a fixed shell, a sliding block, and a locking block. By squeezing the pressing block, the sliding rod moves, which in turn moves the moving plate and the locking block to the inside of the moving groove. Then, the sliding block moves to the inside of the fixed shell through the fixing groove. When the squeezing of the pressing block is released, the return spring causes the moving plate and the locking block fixed to the moving plate to slide against the locking groove on one side of the sliding shell, thereby fixing the sliding block to the inside of the fixing groove. This makes it easy to install and disassemble and provides strong stability.
[0015] This utility model designs an anti-tangle yarn guiding device for looms. Through design and coordination, components such as clamping plates, fixing bolts, and fixing nuts are combined. By rotating the fixing bolts and fixing nuts, the clamping and fixing effect of the clamping plate on the connecting rod and the clamping plate on the connecting rod is relaxed, allowing the user to adjust the position of the connecting rod and the position and angle of the yarn guiding ring as needed.

[0029] Working principle:
[0030] When using this utility model, the user should first press the pressing block 2 on one side of the connecting plate 1. By pressing the pressing block 2, the sliding rod 8 is moved into the moving groove 10 on the inner side of the connecting plate 1. This causes the moving plate 7, which is fixed to the other end of the sliding rod 8 and located inside the moving groove 10, to move synchronously. When the moving plate 7 moves, the locking block 5 fixed to the moving plate 7 will move into the moving groove 10. The moving plate 7 is also fixed with a return spring 9. By pushing the moving plate 7, the return spring 9 is stretched. At this time, the locking block 5 moves to the inner side of the connecting plate 1 under the pull of the moving plate 7. The user can then install the sliding block 4 into the fixing groove 6 opened on the fixing shell 3 fixed on one side of the connecting plate 1. Then, the user releases the pressure on the pressing block 2, causing the locking block 5 and the moving plate 7 to slide against the locking groove 12 opened on the back side of the sliding block 4 under the rebound action of the return spring 9. This firmly fixes the sliding block 4 to the inner side of the fixing shell 3. The sliding block 4 is fixedly connected to the clamping plate 1. 1. A connecting rod 14 is slidably connected to a clamping plate 11, and a clamping plate 17 is slidably connected to the connecting rod 14. A yarn guide ring 16 is fixedly connected to the clamping plate 17. Both the clamping plate 17 and the clamping plate 11 have a round hole. The connecting rod 14 has several round holes. The connecting rod 14 is fixedly connected to the clamping plate 11 by fixing bolts 13 and fixing nuts 15. When the user needs to adjust the yarn guide ring 16, the user only needs to remove the fixing bolts 13 and fixing nuts 15 on the clamping plate 11 and the connecting rod 14 to move the connecting rod 16 freely. Connect rod 14 and adjust the horizontal position of guide ring 16. Then, adjust the angle of guide ring 16 by removing the fixing bolts 13 and fixing nuts 15 between clamping plate 17 and guide ring 16. In this way, the user can adjust the angle and position of guide ring 16 to a certain extent. When removing connecting rod 14, only press and hold block 2. The contraction of the locking block 5 contacts the locking block 5 to restrict the sliding block 4. Then the user can remove the sliding block 4 from the inside of the fixed shell 3 by moving the sliding block 4.
[0031] In this utility model, the fixing bolt 13, fixing nut 15, return spring 9 and other components are all existing technologies, and their working principle is consistent with similar products on the market, so they will not be described in detail here.
