Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn guiding, and more particularly to a guide yarn guide nozzle. Background Technology
[0002] In the textile industry, yarn drawing is a crucial step in the production process, and its quality directly affects fabric quality and production efficiency. The yarn guide, as an important tool for guiding the yarn, plays an indispensable role in textile machinery.
[0003] Traditional yarn guide nozzles have several drawbacks in the yarn guiding process. Firstly, the friction is significant during the yarn's entry and exit from the nozzle. Due to the lack of effective drag reduction design, considerable friction easily occurs at the contact point between the yarn and the nozzle. This not only increases yarn wear, leading to fuzzing and breakage on the yarn surface, affecting its strength and appearance quality, but also causes unstable yarn tension during traction, consequently affecting the fabric's uniformity and texture. For example, on high-speed textile production lines, frequent yarn breakage due to excessive friction between the yarn and the nozzle severely impacts production continuity and efficiency. Utility Model Content

[0033] By setting a guide-type yarn guide body 1, including the yarn guide body 1, the U-shaped seat 2, and the guide unit 3, the function of guiding the yarn in and out is realized, which helps to improve the stability and accuracy of yarn traction and meet the needs of textile process.
[0034] The yarn guiding unit 6 includes a bearing seat 8 with a fixed yarn outlet end 4 and a rolling bearing 9 disposed in the bearing seat 8. The bearing seat 8 has a yarn outlet channel for yarn outlet, and the rolling bearing 9 is arranged in the bearing seat 8 along both sides of the outlet of the yarn outlet channel.
[0035] By setting the yarn feeding unit 6, which includes a bearing seat 8 and a rolling bearing 9, the bearing seat 8 has a yarn feeding channel and the rolling bearing 9 is arranged on both sides of the yarn feeding channel outlet. By utilizing the rolling characteristics of the rolling bearing 9, the friction force when the yarn is fed out can be effectively reduced, so that the yarn can be fed out smoothly, reduce yarn wear, and ensure yarn quality.
[0036] The bearing housing 8 includes a first clamping block 10 and a second clamping block 11 clamped on the yarn outlet end 4. The first clamping block 10 has sliding parts 12 on both sides of its opening along the yarn outlet channel to reduce yarn resistance.
[0037] By setting the bearing seat 8 to include a first clamping block 10 and a second clamping block 11 clamped on the yarn outlet end 4, and the first clamping block 10 is provided with sliding parts 12 on both sides of the yarn outlet channel opening, it is convenient to install and fix the bearing seat 8. At the same time, the sliding parts 12 can further reduce the resistance when the yarn contacts the yarn outlet channel and improve the smoothness of yarn outlet.
[0038] Both the first clamping block 10 and the second clamping block 11 have mounting grooves 13 for accommodating the rolling bearing 9.
[0039] By opening mounting grooves 13 on the first clamping block 10 and the second clamping block 11 to accommodate the rolling bearing 9, the rolling bearing 9 is ensured to be installed securely, while the position of the rolling bearing 9 is restricted, so that the yarn can only pass through the space defined by the rolling bearing 9 and the yarn outlet channel, effectively avoiding the situation where the yarn gets stuck on both sides of the bearing, thereby achieving stable and smooth traction of the yarn from the yarn inlet end 5 to the yarn outlet end 4.
[0040] The yarn feeding unit 7 is a yarn feeding roller 14 used for yarn feeding.
[0041] By setting the yarn feeding unit 7 as a yarn feeding roller 14 for yarn feeding, the yarn feeding roller 14 can guide the yarn smoothly into the yarn nozzle body 1, and contact the yarn in a rolling manner, reducing the yarn feeding resistance, realizing smooth yarn feeding, and optimizing the yarn traction process.
[0042] In this embodiment 2,
[0043] like Figures 1 to 3 As shown, a guided yarn feeder body 1 is provided, including the feeder body 1, the U-shaped seat 2, and the guiding unit 3, to guide the yarn in and out.

The mounting grooves 13 on the first clamping block 10 and the second clamping block 11 for accommodating the rolling bearing 9 securely fix the rolling bearing 9 in a specific position, ensuring that the rolling bearing 9 maintains the correct position and state during yarn extraction, continuously and effectively guiding the yarn and preventing the yarn from getting stuck on both sides of the bearing. This ensures that the rolling bearing 9 maintains the correct position and state during yarn extraction, continuously and effectively guiding the yarn, thereby achieving stable and smooth traction of the yarn from the yarn inlet end 5 to the yarn outlet end 4, meeting the requirements for yarn traction in textile processes.
[0046] In this embodiment 4,
[0047] like Figures 1 to 3 As shown, the working principle of this utility model is as follows:
[0048] 1. Yarn entry stage:
[0049] The yarn enters from the outside and approaches the yarn feeder body 1. The yarn inlet 5 on the U-shaped seat 2 serves to position the yarn's entry direction. When the yarn contacts the inlet roller 14, the roller 14, due to its rotational characteristics, generates friction with the yarn, driving the yarn to move in a specific direction into the yarn feeder body 1. Compared to sliding friction, this rolling friction greatly reduces the resistance of the yarn during its entry into the yarn feeder body 1, allowing the yarn to enter the yarn feeder body 1 smoothly and steadily, avoiding problems such as yarn breakage or fuzzing caused by excessive resistance.
[0050] 2. Transition stage of yarn within the yarn feeder body 1:
[0051] The yarn entering the nozzle body 1 moves towards the exit end 4 under the guidance of the U-shaped seat 2 and the nozzle body 1. During this process, the mating structure of the nozzle body 1 and the U-shaped seat 2 ensures that the yarn's internal path is relatively stable, preventing significant deviation or tangling.
[0052] 3. Yarn drawing stage:
[0053] When the yarn reaches the exit end 4, the yarn exiting unit 6 and the yarn exiting channel on the bearing seat 8 provide a clear exit direction for the yarn. The rolling bearings 9 arranged on both sides of the exit of the yarn exiting channel contact the yarn. As the yarn passes through the exit of the yarn exiting channel, the rolling bearings 9 roll with the movement of the yarn. The rolling friction further reduces the resistance when the yarn is pulled out, allowing the yarn to be smoothly pulled out from the exit end 4.
