Description

Technical Field

[0001] This utility model relates to a yarn guiding mechanism, specifically a dual-channel rapid traction traverse yarn guiding mechanism. Background Technology

[0002] In the modern textile industry, the performance of the yarn guiding mechanism directly affects the efficiency of the weaving process and the quality of the yarn (strength and winding). Traditional yarn guiding systems typically employ a single-channel design, relying on the physical movement of mechanical components to guide the yarn. This design has limitations in terms of flexibility, accuracy, and speed. With increasing production demands, the problems of traditional yarn guiding systems are becoming increasingly prominent in the following aspects:

[0003] 1) When a single-channel yarn guide mechanism reverses direction, adjustments and pauses are usually required. This can lead to over-winding at both ends of the yarn tube during the winding process, resulting in hard edges and bulges. This is especially true in high-speed weaving environments where the need for rapid yarn movement and reversal is even more urgent.

[0004] 2) In single-channel yarn guiding mechanisms, yarn is prone to slipping or tangling during the guiding process, causing production interruptions and yarn loss. This problem not only affects fabric quality but also increases the number of manual interventions and reduces the level of automation.

[0005] 3) Traditional yarn guiding mechanisms have numerous mechanical friction contact areas, leading to accelerated wear of components and generating significant noise during reversing and operation. This not only affects the service life of the equipment but also negatively impacts the operating environment.

[0006] 4) During high-speed operation, the reversal of the yarn guiding mechanism is often accompanied by severe impact forces. These impact forces not only damage the yarn but also cause excessive wear on equipment components. Existing yarn guiding facilities typically lack effective shock absorption and cushioning designs, failing to effectively absorb such impacts and increasing the probability of malfunctions.

[0007] Therefore, to ensure the stability and flexibility of yarn guiding, it is imperative to design a dual-channel fast traction traverse yarn guiding mechanism with a dual-channel design. Utility Model Content

[0044] Reference Figure 4 The working principle diagram shows that the dual-channel rapid traction traverse yarn guiding mechanism, through its unique design and structure, solves the problems of efficiency, stability, and durability in traditional yarn guiding equipment. The following is a detailed description of the mechanism's working principle: In the dual-channel system, the yarn is guided to two independent channels. These two channels can be designed to be parallel or staggered, ensuring that the yarn always stays on a predetermined trajectory during operation. In this way, the yarn is subjected to more even force, reducing the risk of yarn slippage and tangling. The movement of the two channels is synchronously managed by a central control system. The system adjusts the traction speed and direction of the two channels in real time according to the speed of the loom and the movement state of the yarn. This allows the yarn to move quickly and smoothly during reversals, reducing reversal time and thus improving overall weaving efficiency.

[0045] To cope with the impact and vibration generated during high-speed operation, the yarn guiding mechanism is designed with a buffer and shock absorption function, referring to... Figure 6 Its working principle is as follows: applying damping materials (such as rubber or polymer) to key connection parts and moving components of the dual channels can effectively absorb the impact force generated during movement, reducing vibration and noise; by integrating magnets or magnetic materials into the yarn guiding mechanism, attractive forces can be generated during reversal, slowing down sudden stops and changes in movement, thereby further reducing vibration and noise; the overall structure of the yarn guiding mechanism has been optimized, and the reasonable layout of the center of gravity can reduce vibration during high-speed movement, and the stability of the equipment is improved by enhancing rigidity.

[0046] Based on the above working principle, the dual-channel rapid traction traverse yarn guiding mechanism demonstrates superior performance in modern textile production, significantly improving production efficiency and yarn quality, and becoming an important innovation in modern weaving equipment.
