Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and in particular to an automatic feeding mechanism for yarn production. Background Technology

[0002] In continuous production processes of yarn spinning and weaving, the design of the limiting and buffering structure, guiding and positioning structure, and roller conveying transmission structure of the yarn feeding mechanism directly affects the regularity of the yarn conveying trajectory, tension stability, and feeding uniformity. Traditional yarn feeding equipment has a simple structural design and does not have multi-stage elastic limiting and buffering components and gear synchronous roller conveying structure. It has obvious structural shortcomings in anti-deviation, anti-slipping, and tension adaptation capabilities under high-speed feeding conditions.

[0003] Traditional yarn feeding equipment uses only a single set of guide rollers to complete the feeding operation, lacking a multi-stage limiting and buffering mechanical structure. During high-speed yarn conveying, it is difficult to suppress jumping and displacement, which easily leads to structural coordination problems such as yarn stacking, yarn jamming, and yarn breakage. At the same time, traditional feeding equipment lacks a synchronous roller pressing anti-slip conveying structure, which easily causes relative slippage between the roller and the yarn, resulting in insufficient feeding consistency and poor overall conveying stability of the equipment.

[0004] Therefore, this utility model proposes an automatic feeding mechanism for yarn production to solve the mechanical structure problems existing in the above-mentioned background technology. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an automatic feeding mechanism for yarn production. In yarn production conveying and feeding operations, the design of the equipment's multi-roller contact conveying, multi-stage guiding and limiting, and elastic buffer protection structure indirectly affects the stability of yarn conveying, feeding accuracy, and processing quality. Traditional yarn feeding mechanisms have limitations, often employing a single-roller traction feeding structure, lacking multi-roller synchronous conveying, multi-stage limiting, and elastic buffer structures. Their adaptability to various working conditions is limited. Traditional single-roller feeding makes it difficult to achieve uniform contact conveying, and yarn slippage and deviation are prone to occur during operation. Issues such as yarn overlap and uneven and continuous conveying require improvement. Furthermore, traditional structures generally have limited guiding and limiting effects, leading to vibration, deviation, and friction wear during high-speed yarn conveying, which can cause fuzzing, yarn breakage, and increased production losses and defect rates. This also restricts the accuracy and efficiency of automated feeding. To address these shortcomings, this invention proposes an automatic yarn feeding mechanism that employs a limiting and buffering guiding structure combined with a gear-synchronous roller conveying structure. This mechanism enables continuous automatic yarn feeding with high precision and good stability, making it suitable for various yarn production feeding scenarios.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic feeding mechanism for yarn production includes a housing base, characterized in that: an equipment box is provided on the upper end of the outer wall of the housing base, a limiting mechanism is provided on the upper end of the inner wall of the equipment box, a feeding mechanism is provided on the inner wall of the equipment box, the limiting mechanism includes a rotating shaft, the rotating shaft is provided on the top ends of both sides of the inner wall of the equipment box, a fixed seat is rotatably connected to the outer wall of the rotating shaft, a limiting roller is rotatably connected to the inner wall of the fixed seat, and a yarn feeding port is provided on both sides of the inner wall of the equipment box, with a fixing ring fixedly connected to the yarn feeding port; Through the above technical solution, the box base serves as the overall load-bearing base of the equipment, providing stable support for the upper equipment box and various internal functional mechanisms, ensuring the overall rigidity of the equipment operation. The equipment box is used to centrally house and install the limiting mechanism and the conveying mechanism, realizing an integrated structural layout. The limiting mechanism is arranged on the upper part of the inner wall of the equipment box, which can guide, limit, and buffer the incoming yarn, improve the problems of yarn deviation and jumping during high-speed conveying, ensure that the yarn conveying trajectory is relatively regular, and provide basic conditions for stable feeding.

[0007] Furthermore, the material conveying mechanism includes a motor, which is located on the rear side of the outer wall of the equipment box. A rubber roller is provided in the middle of the inner wall of the equipment box, and a drive gear is provided on one side of the outer wall of the rubber roller. The output end of the motor is fixedly connected to the inner wall of the drive gear. Through the above technical solution, the motor, as the power output component of the material conveying mechanism, can drive the active gear to operate stably and provide continuous power for the roller pressing conveying structure. The rubber roller, together with each group of conveying rollers, forms a roller pressing feeding structure. By utilizing its own material properties, it can improve the yarn adhesion friction, alleviate the yarn conveying slippage problem, and ensure relatively good feeding uniformity and continuity.

[0008] Furthermore, a limit spring is provided on the outer wall of the fixing ring; Through the above technical solution, the limiting spring has elastic buffering performance, which can elastically buffer and adjust the tension fluctuations and instantaneous jumps generated by high-speed yarn conveying, weaken the yarn shaking amplitude, alleviate the uneven tension, and help improve the stability of the yarn feeding.

[0009] Furthermore, a limit ring is provided at the top of the outer wall of the limiting spring; Through the above technical solution, the limiting ring can limit and constrain the inserted yarn on the outer ring, reducing the possibility of the yarn shifting to the left or right. Combined with the limiting spring, it can achieve an integrated effect of buffering and limiting, and further regulate the yarn conveying path.

[0010] Furthermore, driven gears are meshed on both sides of the outer wall of the driving gear; Through the above technical solution, when the driving gear rotates, it can synchronously mesh and drive the driven gears on both sides to operate in conjunction, realizing synchronous transmission of multiple sets of rollers, ensuring that the speed of each conveying point is basically the same, and reducing the problems of yarn pulling and accumulation caused by speed differences.

[0011] Furthermore, a rotating roller is provided on one side of the outer wall of the driven gear; Through the above technical solution, the driven gear drives the rotating roller to rotate synchronously, and the continuous feeding and conveying of yarn is achieved by the coordinated cooperation of multiple sets of rotating rollers, ensuring the continuity and stability of the feeding operation.

[0012] Furthermore, a feeding groove is provided on the inner wall of the rotating roller; Through the above technical solution, the feeding trough can provide a dedicated conveying and limiting channel for the yarn, radially limiting the yarn, reducing the probability of yarn slippage and deviation, and further improving the feeding regularity.

[0013] Furthermore, a limit stop shaft is provided on one side of the outer wall of the rotating roller; Through the above technical solution, the limiting stop shaft can provide lateral limiting protection for the yarn, reduce the possibility of the yarn slipping and coming off to both sides during the conveying process, ensure that the yarn is basically in the conveying position, and reduce the probability of yarn jamming and derailment failures.

[0014] This utility model has the following beneficial effects: 1. This utility model is equipped with a multi-level limiting buffer guide structure. The limiting spring and limiting ring at the yarn inlet position realize elastic buffering and outer ring limiting of the yarn entry, which can alleviate the tension fluctuation and jumping problem caused by high-speed yarn conveying, improve the uneven yarn tension, and, together with the rotatable limiting roller, guide and constrain the yarn trajectory, which can reduce the yarn conveying deviation and offset, reduce the probability of failures such as yarn stacking, yarn jamming, and yarn breakage, and help ensure the continuity of yarn spinning and weaving production.

[0015] 2. This utility model adopts a gear synchronous transmission combined with an anti-slip roller pressing conveyor structure. Relying on the motor to drive the gear set to operate synchronously, multiple sets of rotating rollers are fed synchronously. The feeding speed is uniform and the synchronization is relatively good. Combined with the anti-slip adhesion characteristics of the rubber roller, it can improve the disadvantage of the yarn slipping easily between the yarn and the roller body in traditional equipment. It helps to improve the uniformity of yarn feeding and the stability of conveying, facilitates the uniformity of yarn processing quality, and improves the overall production and processing quality. The equipment has a compact overall structure, a high degree of automation, and relatively stable operation. It can adapt to continuous yarn feeding operations under different working conditions, has good versatility and practicality, and has good promotional value. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Please refer to Figures 1 to 5 This utility model provides an automatic feeding mechanism for yarn production. In the existing continuous production process of yarn spinning and weaving, equipment is needed to continuously and stably feed and transport the yarn automatically. Traditional feeding equipment has a simple structure and mostly relies on a single set of guide rollers for feeding, lacking a multi-stage limiting and buffering structure. During high-speed conveying, the yarn is prone to jumping, deviation, and uneven tension, which may lead to yarn stacking, jamming, and breakage, affecting the continuity of production. At the same time, the conveying stability of traditional feeding structures is relatively limited, and the yarn is prone to slippage with the rollers, resulting in insufficient feeding uniformity and inconsistent yarn processing quality. To improve the above-mentioned technical defects at the structural level, this utility model provides an automatic feeding mechanism for yarn production, which adopts a limiting and buffering guiding structure combined with a gear synchronous roller pressing conveying structure. The feeding is stable, prevents deviation, and prevents slippage, enabling continuous automatic feeding of yarn with high precision. It includes a box base 1, an equipment box 2 is provided on the upper part of the outer wall of the box base 1, a limiting mechanism 3 is provided on the upper part of the inner wall of the equipment box 2, and a conveying mechanism 4 is provided on the inner wall of the equipment box 2.

[0020] Please refer to Figures 1 to 5 This utility model provides an embodiment of an automatic feeding mechanism for yarn production, including a box base 1, with an equipment box 2 fixedly mounted on the upper end of the box base 1. The equipment box 2 is equipped with a limiting mechanism 3 and a conveying mechanism 4 from top to bottom inside. This utility model replaces the traditional simple feeding structure with a single guide roller by matching the front elastic limiting buffer guide structure with the rear gear synchronous roller pressing conveying structure. It can effectively improve the problems of vibration and deviation, uneven tension, easy slippage and breakage, and poor feeding accuracy of traditional yarn feeding. The structure is compact, the yarn is neat, and the conveying is uniform and stable, which can be well adapted to the high-speed continuous production of yarn.

[0021] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 The limiting mechanism 3 includes a rotating shaft 301, which is disposed at the top of both sides of the inner wall of the equipment box 2. A fixed seat 302 is rotatably connected to the outer wall of the rotating shaft 301. A limiting roller 303 is rotatably connected to the inner wall of the fixed seat 302. A cable inlet 304 is provided on both sides of the inner wall of the equipment box 2. A fixed ring 305 is fixedly connected to the cable inlet 304. A limiting spring 306 is provided on the outer wall of the fixed ring 305. A limiting ring 307 is provided at the top of the outer wall of the limiting spring 306.

[0022] The limiting mechanism 3 is the core structure for guiding, limiting, and buffering tension at the yarn inlet of this equipment. It is used to achieve regular yarn inlet guidance, elastic buffering, and anti-deviation limiting. The yarn enters the equipment through the inlet 304. The limiting ring 307 and the limiting spring 306 form an elastic buffer structure, which can adaptively expand and contract elastically with the tension fluctuations during the high-speed yarn conveying process. It effectively absorbs the yarn bounce, buffers the instantaneous tension impact, and reduces the probability of yarn vibration deviation and tension fluctuations. The limiting roller 303 can rotate freely and follow the rotation of the rotating shaft 301 and the fixed seat 302. It can rotate synchronously with the yarn feeding direction to limit and guide the yarn left and right, reduce the yarn deviation and overlap, and make the yarn conveying trajectory relatively regular and centered, which can provide a reliable inlet foundation for stable feeding at the back end.

[0023] Please refer to Figures 1 to 3 The material conveying mechanism 4 includes a motor 401, which is located on the rear side of the outer wall of the equipment box 2. A rubber roller 402 is located in the middle of the inner wall of the equipment box 2. A drive gear 403 is located on one side of the outer wall of the rubber roller 402. The output end of the motor 401 is fixedly connected to the inner wall of the drive gear 403. Driven gears 404 are meshed on both sides of the outer wall of the drive gear 403. A rotating roller 405 is located on one side of the outer wall of the driven gear 404. A feeding groove 406 is opened on the inner wall of the rotating roller 405. A limit stop shaft 407 is located on one side of the outer wall of the rotating roller 405.

[0024] The conveying mechanism 4 is the power transmission and precision feeding execution structure of this equipment. It is used to realize synchronous rolling and anti-slip continuous conveying of yarn. During operation, the motor 401 provides the conveying power and drives the drive gear 403 to rotate. Utilizing the gear meshing transmission principle, the drive gear 403 synchronously drives the driven gears 404 on both sides to rotate at the same speed, so that the two sets of rotating rollers 405 rotate synchronously in the same direction, which helps to ensure that the feeding speed is relatively uniform. The rubber roller 402 has good friction and anti-slip performance, which can increase the tightness of the fit between the yarn and the roller body and reduce the problems of slippage and uneven feeding at high speed. The rotating roller 405 has a feeding groove 406 inside to position and store the yarn. With the side limit stop shaft 407, it realizes lateral anti-detachment limit, which can effectively reduce the risk of yarn detachment and misalignment, and help to ensure the continuous and stable feeding and conveying effect of yarn.

[0025] Working principle: When the automatic feeding mechanism for yarn production is working, the yarn to be conveyed passes sequentially through the feed inlets 304 and limit rings 307 on both sides of the equipment box 2, and is neatly arranged inside the feed trough 406 of the limit roller 303 and the feeding mechanism 4, completing the yarn feeding assembly. After the production line starts, the yarn is continuously fed and conveyed. The limit spring 306 and limit ring 307 at the inlet end adaptively buffer the jumping and tension fluctuations caused by the high-speed movement of the yarn. The limit roller 303 rotates with the yarn feed, which can limit and correct the yarn conveying trajectory, reducing deviation and shaking. The probability of the problem occurring is reduced. At the same time, the motor 401 starts and drives the active gear 403 to run. Through the synchronous meshing of the gears, the rotating rollers 405 on both sides rotate synchronously. With the anti-slip contact of the rubber roller 402, the yarn is uniformly rolled and conveyed. The limit stop shaft 407 provides lateral limit and anti-loosening for the yarn. The overall equipment, through the combination of front-end buffer limit and rear-end synchronous rolling and conveying structure, can achieve continuous automatic feeding of yarn with low vibration, low slippage and low deviation, which is conducive to ensuring a relatively continuous and stable production state of spinning and weaving processes.

[0026] This invention optimizes and improves upon the technical shortcomings of traditional yarn feeding mechanisms, which include simple structure, lack of buffer and limiting, easy slippage during conveying, easy yarn deviation, easy yarn breakage and jamming, and poor feeding uniformity. It is not a simple structural addition; instead, it incorporates a front-end elastic limiting and buffering structure, effectively mitigating tension fluctuations and yarn bounce during high-speed conveying. This results in relatively neat yarn movement and better tension stability. The gear-synchronous transmission roller conveying structure allows for multi-roller synchronous operation, ensuring excellent feeding uniformity. Combined with rubber anti-slip rollers and a lateral limiting structure, it significantly reduces the probability of slippage, yarn breakage, and jamming, minimizing equipment downtime. The overall structure is compact, highly automated, and exhibits good operational stability, effectively improving continuous yarn production efficiency and finished product quality. It is adaptable to feeding operations on spinning and weaving production lines for different yarn specifications, possessing significant practicality and industry promotion value.
