Description

Technical Field

[0001] This utility model relates to the field of yarn production, and more specifically, it relates to a yarn guide rod. Background Technology

[0002] As a key component for guiding yarn, the diameter of the guide hole in the yarn guide rod directly affects yarn tension and operational stability. Traditional yarn guide rods are typically made of metal or ceramic and are integrally machined, with a fixed-diameter through-hole structure for the guide hole. When it is necessary to adjust the yarn type or process parameters, because the diameter of the guide hole cannot be changed, operators must stop the machine to disassemble and replace the entire yarn guide rod assembly. Especially in small-batch, multi-variety production modes, this replacement operation occurs frequently, severely impacting equipment utilization.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a yarn guide rod.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn guide rod, including a rod body, a yarn guide plate integrally formed at the top of the rod body, a first yarn guide hole formed on the yarn guide plate, an upper plate and a lower plate rotatably connected to the yarn guide plate by a knob, the upper plate and the lower plate being located on the upper and lower sides of the yarn guide plate respectively, the knob being used to tighten to restrict the rotation of the upper plate and the lower plate, a second yarn guide hole formed on the upper plate, and a third yarn guide hole formed on the lower plate, the diameters of the second yarn guide hole and the third yarn guide hole are both smaller than the diameter of the first yarn guide hole, and the diameters of the second yarn guide hole and the third yarn guide hole are different.

[0006] The present invention is further configured such that the diameter of the second yarn guide hole is smaller than the diameter of the third yarn guide hole.

[0007] The present invention is further configured such that the first yarn guide hole, the second yarn guide hole, and the third yarn guide hole are each divided into two groups, and the diameter of the first group of the first yarn guide hole, the second yarn guide hole, and the third yarn guide hole is smaller than the diameter of the corresponding second group of the first yarn guide hole, the second yarn guide hole, and the third yarn guide hole.

[0008] The present invention is further configured such that: the end of the upper plate away from the knob and the end of the lower plate away from the knob are both provided with push grooves for rotation.

[0009] The present invention is further configured such that the two push grooves are oriented in opposite directions.

[0010] The present invention is further configured such that the edges of the first yarn guide hole, the second yarn guide hole, and the third yarn guide hole are rounded.

[0011] In summary, this utility model has the following beneficial effects: the adjustable multi-layer yarn guide plate system enables rapid switching of the yarn guide aperture and avoids cumbersome disassembly and installation steps, allowing a single yarn guide rod to adapt to various yarns, significantly improving the adjustment efficiency and production flexibility of textile equipment.

[0013] In the diagram: 1. Rod body; 2. Yarn guide plate; 3. First yarn guide hole; 4. Knob; 5. Upper plate; 6. Lower plate; 7. Second yarn guide hole; 8. Third yarn guide hole; 9. Push groove. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Example: A yarn guide rod, such as Figure 1 , Figure 2 As shown, the rod body 1 is made of high-strength aluminum alloy with an anodized surface. A yarn guide plate 2 is obliquely connected to the top of the rod body 1. The yarn guide plate 2 has a rectangular structure, 8-10mm thick, and is integrally formed with the rod body 1. A first yarn guide hole 3 is machined on the yarn guide plate 2. The upper and lower surfaces of the yarn guide plate 2 are connected to a rotatable upper plate 5 and lower plate 6 via a knob 4 with a threaded rod. The rotation axis is located at one end of the yarn guide plate 2, and the knob 4 controls the tightening. Both the upper plate 5 and lower plate 6 are injection molded from special engineering plastics, making them lightweight and wear-resistant.

[0016] like Figure 1 , Figure 2 As shown, the upper plate 5 has a second yarn guide hole 7, with a diameter 0.3-0.5mm smaller than the first yarn guide hole 3. The lower plate 6 has a third yarn guide hole 8, with a diameter 0.1-0.3mm smaller than the first yarn guide hole 3. The second yarn guide hole 7 is the smallest and is positioned at the top for easy observation during yarn feeding. All yarn guide holes have rounded polished edges, with a surface roughness controlled below Ra0.4 to ensure smooth yarn passage without damage. The upper plate 5 and lower plate 6 have oppositely oriented push grooves 9 at the ends furthest from the knob 4 for easy finger rotation. To accommodate different yarn requirements, the yarn guide plate 2 has two sets of yarn guide hole systems, designed for fine and coarse yarns respectively, with a diameter difference of 0.2-0.4mm between sets.

[0017] When using, select the appropriate combination of yarn guide holes according to process requirements. After loosening knob 4, rotate the upper plate 5 or the lower plate 6 individually. When the edges of both coincide with the edge of the yarn guide plate 2, the required second yarn guide hole 7 or third yarn guide hole 8 is aligned with the first yarn guide hole 3. Then tighten knob 4 to secure it. The design of the push groove 9 allows the operator to quickly and accurately complete the hole diameter switching without disassembling any parts. When thorough cleaning is required, knob 4 can be completely removed, and the upper plate 5 and lower plate 6 can be removed for deep maintenance.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
