Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and in particular to a yarn guiding mechanism for a spinning frame. Background Technology

[0002] Against the backdrop of the textile industry's development towards refinement and efficiency, the performance of the yarn guiding mechanism of the spinning frame directly affects the quality and efficiency of yarn production, but traditional yarn guiding mechanisms have obvious technical shortcomings.

[0003] On the one hand, traditional yarn guiding mechanisms are mostly mechanical transmissions or fixed structures, lacking precise control capabilities. During yarn guiding, insufficient speed and trajectory control easily leads to tension fluctuations, resulting in frequent breakage and tangling problems, and serious waste of raw materials; moreover, long-term friction between the components and the yarn generates fuzz, making it difficult to meet the yarn quality requirements of the high-end market.

[0004] On the other hand, traditional yarn guiding mechanisms have poor process adaptability, fixed layout, and difficulty in quickly switching production parameters for different yarn types. When companies adjust processes such as winding density and forming angle, they need to disassemble and reassemble a large number of equipment, which increases labor costs and reduces production flexibility.

[0005] Furthermore, traditional yarn guiding mechanisms are complex to install and have high maintenance costs. High frictional losses between components not only shorten equipment lifespan but also result in high energy consumption and noise. Their distributed layout leads to numerous points of failure, making troubleshooting and repair time-consuming and severely impacting production continuity. Therefore, developing a new type of yarn guiding mechanism that is high-precision, easily adjustable, and convenient to maintain has become crucial for the textile industry to enhance its competitiveness.

Detailed Implementation

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] Example

[0020] Please refer to the accompanying drawings in the specification. In this embodiment of the utility model, a yarn guiding mechanism for a spinning machine includes a mounting frame 1, a mounting shaft 2, multiple adjusting components, and multiple yarn guiding components. The bottom end of each adjusting component is provided with a fixing member 3. The multiple adjusting components are evenly arranged on the mounting shaft 2 through the fixing members 3, and the yarn guiding components are arranged on the adjusting components.

[0021] The yarn guiding assembly includes a drive motor 4, a rotating shaft 5, a U-shaped seat 6, and a rotating wheel 7. The drive motor 4 is mounted on the U-shaped seat 6 via a motor mount. Both ends of the rotating shaft 5 are mounted on the U-shaped seat 6 via shaft seats. One end of the rotating shaft 5 is connected to the output end of the drive motor 4. The rotating wheel 7 is mounted on the rotating shaft 5.

[0022] The adjustment assembly includes a fixed base 8, a movable plate 9, a slide 10, a second drive motor 11, a gear 12, a first rack 13, a second rack 14, and a third rack 15. The top of the fixed base 8 has a rectangular groove, and the first rack 13 and the second rack 14 are respectively arranged on both sides of the rectangular groove. The first rack 13 and the second rack 14 are fixedly arranged on the fixed base 8. The third rack 15 is arranged in the middle of the first rack 13 and the second rack 14. The third rack 15 is fixedly arranged on the top of the movable plate 9. The movable plate 9 is movably arranged inside the rectangular groove. The top of the movable plate 9 is provided with a support frame 16, and the top of the support frame 16 is fixedly connected to the yarn guide assembly.

[0023] The fastener 3 includes an upper arc and a lower arc, which are fixedly connected by bolts.

[0024] The U-shaped seat 6 is provided with a mounting plate 17. The mounting plate 17 has a vertically threaded hole in the middle position. The top of the mounting plate 17 is provided with a limiting seat 18. The limiting seat 18 has a limiting hole 19. The limiting seat 18 is fixedly installed on the mounting plate 17 by bolts 20.

[0025] The surface of the rotating wheel 7 is provided with a ceramic layer and a PTFE lubricating layer, with the ceramic layer located at the bottom end of the PTFE lubricating layer. Similarly, the surface of the limiting hole 19 is also provided with a ceramic layer and a PTFE lubricating layer, with the ceramic layer located at the bottom end of the PTFE lubricating layer. The ceramic layer has high hardness and strong wear resistance, which can extend the service life of the rotating wheel and reduce wear and deformation during long-term use. The PTFE lubricating layer has a low coefficient of friction, which can reduce the frictional resistance between the yarn and the rotating wheel, preventing the yarn from becoming fuzzy or damaged due to friction, and improving yarn quality.

[0026] Working Principle: After the equipment starts, drive motor one drives the rotating shaft to rotate, which in turn drives the rotating wheel. The ceramic layer and PTFE lubricating layer on the surface of the rotating wheel reduce friction, precisely control the yarn movement trajectory and tension, avoid breakage and tangling, and ensure smooth yarn guiding. When process parameters need to be adjusted, drive motor two drives the gear to rotate, which meshes with the fixed rack and drives the moving plate to slide laterally in the rectangular groove, so that the yarn guiding components are synchronously displaced, and parameters such as winding density and forming angle can be quickly adjusted. In addition, the upper and lower arc bolt fixing parts can flexibly adjust the spacing of the adjustment components on the mounting shaft to adapt to the production of different yarns. The mounting plate on the U-shaped seat is fixed to the limit seat by bolts, and the limit hole constrains the yarn entry and exit direction. Together with the ceramic-PTFE composite layer on the surface of the rotating wheel, friction is reduced and yarn deviation is prevented, ensuring the stability of the yarn guiding path and improving yarn quality.

[0027] In the above process, the drive motor in the yarn guiding assembly directly drives the rotating shaft and the wheel, which can precisely control the speed and trajectory of the yarn during guidance, effectively suppressing tension fluctuations, significantly reducing the probability of yarn breakage and tangling, and reducing material waste. The ceramic layer and PTFE lubricating layer on the surface of the wheel and the limiting hole form a double protection. The ceramic layer is wear-resistant and damage-resistant, while the PTFE lubricating layer reduces the coefficient of friction, preventing yarn fuzzing and meeting the stringent requirements of the high-end market for yarn quality. The drive motor in the adjusting assembly uses a linkage gear and rack structure to drive the moving plate to slide flexibly within the rectangular groove, thereby causing the yarn guiding assembly to move laterally. This design allows for quick adjustment of process parameters such as winding density and forming angle when switching between different yarn types, without the need for cumbersome equipment disassembly and reassembly, significantly reducing labor costs and improving production flexibility and efficiency. The fasteners utilize upper and lower arc bolt connections, ensuring the adjustment components are evenly and securely mounted on the mounting shaft. This allows for flexible adjustment of the yarn guide component spacing according to actual production needs, accommodating various yarn specifications. The integrated layout of the yarn guide mechanism, with mounting frames and shafts, neatly integrates the components. Compared to traditional distributed structures, this more concentrated fault points facilitate rapid location and repair, ensuring production continuity. The ceramic and PTFE lubrication layers not only protect the yarn but also reduce frictional wear between components, extending equipment lifespan while lowering energy consumption and operating noise. The mounting plate and limit seat design on the U-shaped base precisely limit the yarn path through internal threaded holes and limit holes, preventing deviation. The structure is simple, and maintenance and disassembly are convenient.

[0028] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
