Description

Technical Field

[0001] This utility model discloses a novel yarn guide nozzle, belonging to the technical field of textile machinery parts. Background Technology

[0002] The yarn feeder is a key component in textile machinery used to guide and stabilize the yarn path. It is typically made of metal or high-strength plastic, and its structural design directly affects the yarn tension and positioning accuracy during the weaving process. Traditional yarn feeders often employ a straight or slightly curved design to adapt to different types of textile equipment and ensure stable yarn delivery.

[0003] In existing technologies, while the straight shape of the yarn feeder is beneficial for universal installation, during high-speed weaving, the yarn is prone to curling outward due to centrifugal force and inertia. This causes the yarn to deviate from its normal path and get caught on the sharp or protruding parts on both sides of the yarn feeder's edge, resulting in problems such as yarn tension imbalance and abnormal weaving. This can not only cause process failures such as yarn breakage and skipped stitches, but also reduce production efficiency due to frequent machine downtime for maintenance. Therefore, in order to solve this problem, a new solution is needed. Utility Model Content

[0004] The purpose of this invention is to provide a novel lead yarn nozzle in order to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a novel yarn guide, comprising a yarn guide head and a yarn guide handle, wherein the yarn guide handle comprises an installation part and a guide part, the guide part is provided with an installation notch, the yarn guide head is disposed within the installation notch, the guide part is provided with a main yarn guide groove and a secondary yarn guide groove, the main yarn guide groove and the secondary yarn guide groove are arranged in a V-shape and converge at the installation notch, and a yarn limiting piece is provided on the front side of the guide part at the installation notch position.

[0006] Preferably, the yarn nozzle is provided with a yarn guide channel, which is connected to the main yarn guide groove and the secondary yarn guide groove, and the end of the yarn nozzle is provided with a main yarn outlet hole and a secondary yarn outlet hole.

[0007] Preferably, the main yarn guide groove and the secondary yarn guide groove form corresponding protrusions on the back side of the guide portion.

[0008] Preferably, the yarn limiting piece is configured as an arched bend, and the direction of the bend is opposite to the concave direction of the main yarn guide groove and the secondary yarn guide groove.

[0009] Preferably, a yarn threading opening is provided between the main yarn guide groove, the secondary yarn guide groove and the yarn guide channel.

[0010] Preferably, the back of the yarn feeder is provided with a yarn-threading opening two.

[0011] Preferably, positioning grooves are provided on both sides of the yarn nozzle, and the ends of the guide portion formed on both sides of the mounting notch are embedded into the positioning grooves.

[0012] Preferably, the mounting part and the guide part are integrally formed, and the yarn nozzle is welded and fixed to the guide part.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The V-shaped arrangement of the main yarn guide groove, the secondary yarn guide groove, and the arched yarn limiting piece work together to form a multi-directional constraint structure. The concave design of the guide groove can limit the lateral deviation of the yarn to both sides during high-speed weaving, while the reverse-curved limiting piece can directly block the yarn and suppress the outward curling of the yarn due to centrifugal force. The combination of the two significantly improves the stability of the yarn path and avoids the risk of the yarn deviating from the normal path and getting caught on the sharp or protruding parts on both sides of the yarn nozzle. This effectively reduces the process failure rate such as yarn breakage and skipped stitches, and ensures production efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] A new type of lead yarn nozzle, such as Figure 1-3 As shown, the device includes a yarn nozzle 1 and a yarn nozzle handle 2, which are manufactured separately and then fixed together. This allows for the use of yarn nozzle 1 and yarn nozzle handle 2 with different structures to meet different needs, or the same yarn nozzle handle 2 to be paired with different yarn nozzle 1, thus adapting to different equipment. The yarn nozzle handle 2 includes an installation part 3 and a guide part 4, which are integrally formed. The installation part 3 is used to install the yarn nozzle on the equipment, and the guide part 4 is used to guide the yarn. The bottom of the guide part 4 is provided with an installation notch 5, and the yarn nozzle 1 is placed in the installation notch 5. Positioning grooves 15 are provided on both sides of the yarn nozzle 1. The ends formed on both sides of the guide part 4 at the installation notch 5 are embedded into the positioning grooves 15. After the embedding and installation are completed, the yarn nozzle 1 and the guide part 4 are welded and fixed.

[0021] The guide section 4 is provided with a main yarn guide groove 6 and a secondary yarn guide groove 7, which are arranged in a V-shape and converge at the installation notch 5. The main yarn guide groove 6 and the secondary yarn guide groove 7 are used to guide the main yarn and the secondary yarn, respectively. Since both guide grooves are grooves, they can limit the lateral deviation of the yarn to both sides during high-speed weaving. The main yarn guide groove 6 and the secondary yarn guide groove 7 form corresponding protrusions 12 on the back of the guide section 4. Therefore, both guide grooves are recessed structures. In addition to having a better restraining effect on the yarn, when the equipment closes the yarn nozzles and retracts them side by side, it can also realize the nesting of adjacent yarn nozzles to prevent the yarn nozzles from loosening.

[0022] A yarn limiting piece 8 is provided on the front of the guide part 4 at the mounting notch 5. The yarn limiting piece 8 is horizontally placed at the intersection of the main yarn guide groove 6 and the secondary yarn guide groove 7, which can directly block the yarn and suppress the outward movement of the yarn due to centrifugal force. The yarn limiting piece 8 is designed as an arched curve, and the direction of the curve is opposite to the concave direction of the main yarn guide groove 6 and the secondary yarn guide groove 7. Therefore, it has more space when threading the yarn, making it easier to thread the yarn.

[0023] The yarn nozzle 1 is provided with a yarn guide channel 9, which is connected to the main yarn guide groove 6 and the secondary yarn guide groove 7. After passing through the main yarn guide groove 6 and the secondary yarn guide groove 7, the main yarn and the secondary yarn will converge on the yarn guide channel 9 and continue to be guided downward. The end of the yarn nozzle 1 is provided with a main yarn outlet hole 10 and a secondary yarn outlet hole 11. The main yarn will eventually pass out from the main yarn outlet hole 10, and the secondary yarn will pass out from the secondary yarn outlet hole 11.

[0024] A yarn threading opening 13 is provided between the main yarn guide groove 6, the secondary yarn guide groove 7, and the yarn guide channel 9. When threading the yarn, the yarn can first be fed into the yarn threading opening 13 from one side of the main yarn guide groove 6 and the secondary yarn guide groove 7, and then come to the back of the yarn nozzle. The yarn is then threaded between the yarn guide channel 9 and the yarn limiting piece 8. Since the yarn guide channel 9 is aligned with the main yarn guide groove 6 and the secondary yarn guide groove 7, it is also a recessed design. This threading method makes threading the yarn the most convenient. A yarn threading opening 2 14 is provided on the back of the yarn nozzle 1, which adopts the same threading method as the yarn threading opening 13, making the threading of the yarn exit even more convenient.

[0025] In summary, this invention utilizes the V-shaped arrangement of the main yarn guide groove 6 and the secondary yarn guide groove 7, along with the arched yarn limiting piece 8, to form a multi-directional constraint structure. The concave design of the guide grooves restricts the lateral deviation of the yarn to both sides during high-speed weaving, while the reverse-curved limiting piece directly blocks the yarn, suppressing the outward curling of the yarn due to centrifugal force. The combination of these two elements significantly improves the stability of the yarn path, avoiding the risk of the yarn deviating from the normal path and getting caught on the sharp or protruding parts on both sides of the yarn nozzle. This effectively reduces the rate of process failures such as yarn breakage and skipped threads, ensuring production efficiency.
