Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn conducting mechanism. Background Art
[0002] In textile production, the yarn guide mechanism plays a vital role. It works together through a series of precise mechanical components to ensure that the yarn can be smoothly transmitted along the established path, thus avoiding entanglement and knotting between the yarns. This not only improves production efficiency, but also ensures the quality of textiles.
[0003] A conventional yarn conducting mechanism is provided with a bracket, which can provide stable support for the transmission of the yarn. In order to achieve uniform transmission of the yarn and avoid entanglement, a wire loop for the yarn to pass through is generally provided on the bracket. When the yarn continues to pass through, the yarn is likely to scratch the inner wall of the wire loop or the inner wall of the positioning guide hole. If this continues for a long time, it will easily cause the wire loop to break, and the contact area between the yarn and the scratch groove becomes larger, which will increase the sliding resistance of the yarn. When the wire loop has a scratch groove, the entire wire loop needs to be replaced, and the cost of repair and replacement is high. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a yarn guiding mechanism to solve the problem that a scratch groove is scratched on the inner wall of the guide ring or the inner wall of the positioning guide hole, which increases the contact surface between the yarn and the scratch groove and increases the sliding resistance of the yarn.
[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a yarn conducting mechanism, including a conducting ring, and also including:
[0006] An inner ring, wherein the inner ring is coaxially nested in the conductor ring;
[0007] The rotating locking piece is installed between the inner ring and the wire ring.
[0008] The technical principle of the utility model is as follows: when scratches and grooves appear on the inner wall of the inner ring after long-term contact with the yarn, the inner ring can be controlled to rotate relative to the conductor ring by rotating the locking piece, so that the yarn can be adjusted to contact the inner wall of the inner ring at different locations, thereby adjusting the contact point between the yarn and the inner wall of the inner ring, avoiding continuous wear of the inner wall of the inner ring, and improving the service life of the inner ring; it can also ensure that the yarn is not subjected to excessive resistance during transmission, so that the transmission of the yarn is smoother.
[0009] Furthermore, a first notch for embedding the yarn is provided on the conductor ring, and a second notch for embedding the yarn is provided on the inner ring, and the second notch can be communicated with the first notch.
[0010] Through the above arrangement, the inner ring can be controlled to rotate relative to the wire ring by rotating the locking piece, so that the first notch and the second notch overlap, and the yarn can be passed through the first notch and the second notch to be installed in the wire ring and the inner ring, which is convenient for pulling and installing the yarn; if the end of the yarn has been passed through other structures, the yarn can be installed in the wire ring and the inner ring, and the installation of the middle part of the yarn is more convenient.
[0011] Furthermore, the rotating locking member includes a plurality of balls, and the inner wall of the wire ring is provided with a plurality of first embedding grooves for the balls to be embedded, and the first embedding grooves correspond to the balls one by one. The outer wall of the inner ring is provided with a plurality of second embedding grooves for the balls to be embedded, and the depth of the second embedding grooves is 0.1-0.3 times the diameter of the balls.
[0012] Through the above arrangement, the ball can support the rotation of the inner ring when the inner ring rotates relative to the wire ring. At the same time, after the rotation, the ball can be embedded in the corresponding second groove for locking and limiting, so that the inner ring can rotate but cannot rotate freely, making the position adjustment of the inner ring more reliable and facilitating the contact between the yarn and the inner wall of the inner ring at different locations.
[0013] Furthermore, a plurality of mounting grooves connected to the second embedding grooves are provided on the outer wall of the inner ring. The mounting grooves are arranged along the axial direction of the inner ring. The mounting grooves are in sliding contact with the balls. The mounting grooves are located on one end of the inner ring.
[0014] Through the above arrangement, when the inner wall of the inner ring has scratches and grooves after long-term contact with the yarn, the inner ring on the wire ring is pulled out horizontally, and the mounting groove on the inner ring and the ball slide relative to each other. At this time, the inner ring can be removed and trimmed or replaced, and the trimmed or replaced one can be installed on the wire ring again. The inner ring is easy to install and disassemble, and is convenient for trimming or replacement.
[0015] Furthermore, a lever is provided on the end surface of the inner ring, and the lever is located on an end of the inner ring away from the mounting slide groove.
[0016] Through the above arrangement, it is easier to apply force to the inner ring through the lever, making the rotation and disassembly of the inner ring more labor-saving.
[0017] Furthermore, the width of the second notch is smaller than the width of the first notch.
[0018] Through the above arrangement, the second notch and the first notch can be overlapped or misaligned, so that the inner ring and the wire ring can fit tightly.
[0019] Furthermore, the center angle of the first notch is less than or equal to 25°, and the center angle of the first notch is greater than or equal to 10°.
[0020] Through the above arrangement, the size of the first gap is precisely controlled so that the first gap is neither too large nor too small, so that the wire loop still has a stable wire capacity and is easy to overlap or misalign with the second gap. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0026] This embodiment is basically Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the utility model proposes a yarn conducting mechanism, including a conducting ring 10, an inner ring 20 and a rotation locking member, wherein the inner ring 20 is coaxially nested in the conducting ring 10; the rotation locking member is installed between the inner ring 20 and the conducting ring 10.
[0027] like Figure 1-3 As shown, the wire loop 10 is provided with a first notch 101 for embedding the yarn, and the inner ring 20 is provided with a second notch 201 for embedding the yarn. The second notch 201 can be connected to the first notch 101, and the width of the second notch 201 is smaller than the width of the first notch 101; the central angle occupied by the first notch 101 is 23°.
[0028] like Figure 2 and Figure 3 As shown, the rotating locking member includes a plurality of balls 40, and the inner wall of the wire loop 10 is provided with a plurality of first embedding grooves 102 for embedding the balls 40, and the first embedding grooves 102 correspond to the balls 40 one by one, and the outer wall of the inner ring 20 is provided with a plurality of second embedding grooves 202 for embedding the balls 40, and the depth of the second embedding grooves 202 is 0.1 times the diameter of the balls 40.
[0029] like Figure 3As shown, a plurality of mounting grooves 203 connected to the second embedding groove 202 are provided on the outer wall of the inner ring 20, and the mounting grooves 203 are arranged along the axial direction of the inner ring 20. The mounting grooves 203 are in sliding contact with the balls 40, and the mounting grooves 203 are located on one end of the inner ring 20; a lever 30 is integrally formed on the end face of the inner ring 20, and the lever 30 is located on the end of the inner ring 20 away from the mounting grooves 203.
[0030] In addition, the inner wall of the inner ring 20 is an arc surface, which facilitates the formation of a stable line contact between the inner wall of the inner ring 20 and the yarn, thereby preventing the yarn from being cut by the sharp parts of the wire ring 10 and the inner ring 20.
[0031] When the yarn conducting mechanism in this embodiment is in use, the operator first manually moves the lever 30 so that the lever 30 drives the inner ring 20 to rotate relative to the conducting ring 10. At this time, the inner ring 20 rotates relative to the ball 40, and the ball 40 can support the inner ring 20 to rotate. When the first notch 101 and the second notch 201 coincide with each other, the yarn can be passed through the first notch 101 and the second notch 201 to be installed in the conducting ring 10 and the inner ring 20, which is convenient for traction and installation of the yarn. If the end of the yarn has been passed through other structures, it is more convenient to install the yarn in the conducting ring 10 and the inner ring 20 through the coincidence of the first notch 101 and the second notch 201, and the installation of the middle part of the yarn is more convenient.
[0032] After the installation of the yarn is completed, the lever 30 is moved again to push the inner ring 20 to continue to rotate in the wire ring 10, so that the middle part of the yarn is in stable contact with the inner wall of the inner ring 20. At this time, the first notch 101 and the second notch 201 are also displaced from each other; in this process, the yarn can be adjusted to contact with different parts of the inner wall of the inner ring 20, so that the contact between the yarn and the inner wall of the inner ring 20 can be adjusted, so as to avoid continuous wear of the inner wall of the inner ring 20 and improve the service life of the inner ring 20; at the same time, all parts of the inner ring 20 can be in contact with the yarn, which can also improve the service life of the inner ring 20.
[0033] When the inner wall of the inner ring 20 has scratches and grooves after being in contact with the yarn for a long time, the lever 30 can be technically moved to change the contact point between the yarn and the inner wall of the inner ring 20 to avoid deepening of the scratches and grooves; at the same time, the lever 30 can be held to pull out the inner ring 20 on the wire ring 10 horizontally, and the mounting groove 203 on the inner ring 20 and the ball 40 can slide relative to each other. At this time, the inner ring 20 can be removed, and the inner ring 20 can be trimmed or replaced, and the trimmed or replaced one can be reinstalled on the wire ring 10. The inner ring 20 is easy to install and disassemble, and is easy to trim or replace.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
