Description

A reciprocating yarn guiding device for a yarn winch Technical Field

[0001] This utility model relates to the field of textile technology of yarn winnowing machines, and in particular to a reciprocating yarn guiding device for yarn winnowing machines. Background Technology

[0002] Yarn reeling machines are widely used in the textile, dyeing, and garment industries. They are important equipment in the yarn post-processing process. Through the processing of yarn reeling machines, yarn can be formed into strands that meet the requirements, which facilitates subsequent transportation, storage, and processing.

[0003] During the winding process, after the yarn exits from the bobbin or cone, it is guided by the yarn guide frame and evenly wound onto the yarn frame. This ensures that the yarn maintains stable tension during its reciprocating motion and prevents it from tangling during winding.

[0004] Currently, wax blocks are often required when guiding yarn. Since the contact position between the wax block and the yarn is often relatively fixed, the wax blocks are worn in the same places, affecting the life of the wax blocks and the waxing effect. At the same time, the yarn threading process is also quite cumbersome, and the operation method needs to be optimized. Summary of the Invention

[0005] The purpose of this invention is to provide a reciprocating yarn guiding device for a yarn winch, which improves the efficiency of wax block usage and facilitates yarn threading.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a reciprocating yarn guiding device for a yarn winch, comprising a mounting frame, a wax block frame, and a yarn guiding frame;

[0007] The top of the mounting frame is equipped with a wax block holder and a yarn guide. After the yarn passes through the yarn guide, it passes through the wax block holder and is connected to the yarn winch. The height of the wax block holder can be adjusted according to its own weight so that it can always remain at the same height as the yarn after wear.

[0008] A further feature of this invention is that the wax block holder includes a slide rod whose outer wall is slidably connected to the mounting bracket, and a limiting plate fixed to the bottom outer side of the slide rod.

[0009] By adopting the above technical solution, the slide bar is mounted on the mounting frame in a linear up-and-down sliding manner.

[0010] A further feature of this invention is that the top of the limiting plate is fixed to the mounting bracket by a first spring.

[0011] By adopting the above technical solution, the upper and lower ends of the first spring are fixedly connected to the mounting bracket and the limiting plate, respectively.

[0012] A further feature of this invention is that a tray is fixed to the outside of the slide bar, and a wax block is placed on the tray.

[0013] By adopting the above technical solution, the wax block is moved upward, causing the contact area between the yarn and the wax block to change, thereby improving the service life of the wax block.

[0014] A further feature of this invention is that the yarn guide frame includes a fixed rod fixed to the surface of the mounting frame, a fixed yarn piece fixed to the outer wall of the fixed rod, a movable yarn piece slidably disposed on the fixed rod, and a positioning component for fixing the movable yarn piece.

[0015] By adopting the above technical solution, the yarn can pass through the threading hole under the close clamping of the two yarn pieces, and then bypass the wax block to connect with the yarn winch.

[0016] A further feature of this invention is that a screw is coaxially fixed to the top end of the fixing rod.

[0017] A further feature of this invention is that the positioning assembly includes a screw cap threaded to the outside of the screw, a second spring whose bottom end abuts against the movable yarn sheet, and a positioning bracket inserted into the screw.

[0018] By adopting the above technical solution, when the yarn needs to be threaded through the threading hole, the movable yarn piece can be moved upward.

[0019] A further feature of this invention is that the positioning frame includes a support plate that is inserted into the screw, a hook piece whose top end is fixedly connected to the support plate, and a hook block fixed to the side of the hook piece near the outer edge of the movable yarn piece.

[0020] By adopting the above technical solution, the top of the second spring abuts against the support plate, and the upper and lower surfaces of the support plate abut against the rotating cap and the fixing rod, respectively.

[0021] A further feature of this invention is that the upper and lower surfaces of the hook block are sloped structures.

[0022] By adopting the above technical solution, it is possible to facilitate the vertical movement of the movable yarn pieces.

[0023] A further feature of this invention is that the hook piece slides against the outer wall of the movable yarn piece via a hook block.

[0024] By adopting the above technical solution, the movable yarn piece can be moved upwards and then push the hook block to move backwards elastically along the slope.

[0025] The beneficial effects of this utility model are:

[0026] When the wax block is in use, it can press down the first spring. When the wax block is worn out and loses weight, the first spring will automatically raise the height of the wax block, allowing the wax block to adjust the contact height with the yarn. This eliminates the need for manual adjustment, improving the lifespan and efficiency of the wax block. In addition, when threading the yarn, simply move the movable yarn piece upwards so that it can cooperate with the hook block to lock in place, freeing up the hands and eliminating the need to constantly touch the yarn piece, thus improving operational convenience.

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] This utility model embodiment specifically provides a reciprocating yarn guiding device for a yarn winch, as shown in Figures 1-3, including a mounting frame 1, a wax block frame 2, and a yarn guiding frame 3.

[0034] The mounting frame 1 is equipped with a wax block holder 2 and a yarn guide 3 at its top. The yarn passes through the yarn guide 3 and then through the wax block holder 2 to connect with the yarn winch. The wax block holder 2 can be adjusted in height according to its own weight so that it can always be at the same height as the yarn after wear and tear, thereby improving the service life of the wax block holder 2.

[0035] Specifically, the wax block holder 2 includes a slide rod 21 whose outer wall is slidably connected to the mounting frame 1, and a limiting plate 22 fixed to the bottom of the outer side of the slide rod 21. The slide rod 21 is mounted on the mounting frame 1 in a linear up-and-down sliding manner.

[0036] The top of the limiting plate 22 is fixed to the mounting frame 1 by the first spring 23, and the upper and lower ends of the first spring 23 are fixedly connected to the mounting frame 1 and the limiting plate 22 respectively.

[0037] The slide bar 21 has a tray 24 fixed on its outer side, and a wax block 25 is placed on the tray 24. The wax block 25 is inserted into the slide bar 21. After the yarn is wound, it will contact the upper outer side of the wax block 25. After the yarn is frequently wound, the wax block 25 will wear down at the point of contact with it. The weight-reduced wax block 25 will be lifted by the first spring 23, so that the point of contact between the yarn and the wax block 25 will be replaced, thereby improving the service life of the wax block 25.

[0038] Furthermore, the yarn guide frame 3 includes a fixed rod 31 fixed to the surface of the mounting frame 1, a fixed yarn piece 32 fixed to the outer wall of the fixed rod 31, a movable yarn piece 33 slidably disposed on the fixed rod 31, and a positioning component 34 for fixing the movable yarn piece 33. The fixed yarn piece 32 and the movable yarn piece 33 are symmetrically arranged. The fixed rod 31 has an existing threading hole between the two yarn pieces, so that the yarn can pass through the threading hole under the close clamping of the two yarn pieces 33, and then pass around the wax block 25 to connect with the yarn winch. The movable yarn piece 33 can only slide up and down in a straight line along the fixed rod 31.

[0039] Among them, a screw 311 is coaxially fixed at the top of the fixing rod 31.

[0040] In practice, the positioning component 34 includes a screw cap 341 threaded to the outside of the screw 311, a second spring 342 whose bottom end abuts against the movable yarn piece 33, and a positioning frame inserted into the screw 311. When the yarn needs to be threaded into the threading hole, the movable yarn piece 33 can be moved upward so that the movable yarn piece 33 can contact and be positioned with the positioning frame, and then it is convenient to directly thread the yarn into the exposed threading hole.

[0041] Specifically, the positioning frame includes a support plate 343 that is inserted into the screw 311, a hook piece 344 whose top end is fixedly connected to the support plate 343, and a hook block 345 fixed on the side of the hook piece 344 near the outer edge of the movable yarn piece 33. The top end of the second spring 342 abuts against the support plate 343, and the upper and lower surfaces of the support plate 343 abut against the screw cap 341 and the fixing rod 31, respectively.

[0042] The hook block 345 has a sloping structure on both the upper and lower sides to facilitate its movement in and out with the movable yarn piece 33.

[0043] During implementation, the entire positioning frame is made of elastic material, such as ABS plastic or elastic metal sheet. The hook plate 344 slides and engages with the outer wall of the movable yarn sheet 33 through the hook block 345. The downward vertical projection of the hook block 345 falls into the range of the movable yarn sheet 33, so that after the movable yarn sheet 33 moves upward, it can push the hook block 345 to move elastically backward along the slope, and then move above the hook block 345. Under the blocking of the hook block 345, the movable yarn sheet 33 can be kept suspended and positioned, which is convenient for threading. It eliminates the need for the hands to hold the movable yarn sheet 33 for a long time, thereby freeing the hands, improving the convenience of threading and achieving the effect of saving effort. After completion, simply move the movable yarn sheet 33 downward to push the hook block 345 back to its original position.

[0044] It is worth noting that when the second spring 342 is compressed, its maximum elastic force is less than the pushing force of the hook block 345 on the movable yarn piece 33, so that the movable yarn piece 33 can maintain a stable suspended position.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
