Description

Technical Field

[0001] This utility model relates to the field of yarn guiding and twisting technology for spinning machines, specifically a yarn guiding and twisting device for spinning machines. Background Technology

[0002] Traditional equipment is not stable enough in terms of installation and fixation. During operation, it is prone to shaking or displacement due to factors such as vibration. This not only affects the stability of the spinning process, but also leads to inconsistent yarn quality, increased defect rate, and seriously affects production efficiency and enterprise economic benefits.

[0003] In terms of position adjustment, the positions of traditional yarn guides and twisting mechanisms are relatively fixed, making it difficult to flexibly change the yarn direction. This makes it extremely inconvenient for operators to collect the twisted yarn, failing to meet the needs of different production scenarios. Moreover, the single yarn direction cannot optimize the tension distribution according to the yarn characteristics, and the yarn is easily damaged by friction and excessive stretching during transmission, affecting the quality of the final product.

[0004] Vibration control is also a major challenge. Traditional equipment lacks effective vibration reduction measures, and the vibrations generated during equipment operation are directly transmitted to the yarn guiding and twisting process, resulting in unstable yarn transmission and frequent yarn breakage. This not only increases production costs but also requires workers to frequently stop the machine for repairs, greatly reducing production efficiency.

[0005] In terms of mechanism connection and maintenance, traditional yarn guiding and twisting mechanisms are complex to install and disassemble, and parts replacement is inconvenient. Once a malfunction occurs, repairs are time-consuming, leading to a significant increase in equipment downtime, severely hindering production progress, and causing enterprises to face substantial downtime losses. Furthermore, the relatively simple design of traditional yarn guiding rollers and twisting rollers results in poor yarn guiding effect and insufficient twisting force and uniformity, making it difficult to produce high-quality, high-performance yarn products and meet market demands for high-end yarns. Therefore, we provide a yarn guiding and twisting device for spinning machines to solve these problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a yarn guiding and twisting device for a spinning machine.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a yarn guiding and twisting device for a spinning machine, comprising a support column and yarn, a base fixed on the support column and a fixing bolt disposed below the support column, a fixing plate disposed on the base, a bearing embedded in the fixing plate, a rotating shaft disposed in the bearing, a fixing frame fixed on the surface of the rotating shaft, a connecting block disposed above the fixing frame via a vibration component, a yarn guiding mechanism and a twisting mechanism disposed on the sides of the fixing frame and the connecting block respectively, the fixing frame and the connecting block being connected by a locking device, the yarn passing through the yarn guiding mechanism and exiting through the twisting mechanism, a universal wheel fixed at the bottom of the fixing frame, and the universal wheel being able to drive the fixing frame to rotate on the base.

[0010] Furthermore, the yarn guiding mechanism includes an upper guide roller and a lower guide roller, with pin holes at both ends of the upper and lower guide rollers, and circular guide grooves evenly distributed on the surface of the upper guide roller.

[0011] Furthermore, the twisting mechanism includes an upper twisting roller and a lower twisting roller, with pin holes at both ends of the upper and lower twisting rollers, and a threaded twisting groove on the surface of the lower twisting roller.

[0012] Furthermore, the fixing frame and the connecting block are fixed with pins on their sides. The fixing frame is movably connected to the lower guide roller in the yarn guiding mechanism and the lower twisting roller in the twisting mechanism through the pins. The connecting block is movably connected to the upper guide roller in the yarn guiding mechanism and the upper twisting roller in the twisting mechanism through the pins.

[0013] Furthermore, the vibration assembly includes a damper fixed on a mounting frame, a spring sleeved on the surface of the damper, and the surfaces of the damper and the spring are fixedly connected to the connecting block.

[0014] Furthermore, the surface of the fixed plate is uniformly provided with positioning holes, and a positioning rod is provided in the positioning hole, with the surface of the positioning rod overlapping the surface of the fixed frame.

[0015] (III) Beneficial Effects:

[0016] Compared with existing technologies, this yarn guiding and twisting device for spinning machines has the following advantages:

[0017] I. This utility model uses a support column and a lower fixing bolt to firmly fix the entire device in a designated position, preventing shaking or displacement during operation, thus laying a solid foundation for stable spinning operations and effectively ensuring spinning quality and efficiency. The fixed plate, together with bearings and a rotating shaft, can drive the fixed frame and the connected yarn guiding and twisting mechanism to rotate. The positioning rod limits the position, which not only changes the yarn direction, making it convenient for operators to collect the twisted yarn at different positions and improving operational convenience, but also optimizes the yarn tension distribution, reduces friction and damage during transmission, and improves yarn quality.

[0018] II. This utility model uses a vibration component consisting of a damper and a spring, which can effectively buffer and absorb the vibration generated by the operation of the device, reduce the interference of vibration on the yarn guiding and twisting process, make yarn transmission and processing more stable, reduce the probability of yarn breakage, and further improve the stability and quality of spinning.

[0019] Third, this utility model uses a fixed frame and a connecting block to be movably connected to the yarn guiding and twisting mechanism via a pin shaft, which facilitates the installation and disassembly of these mechanisms, and is conducive to equipment maintenance and parts replacement, thereby reducing equipment maintenance costs and downtime. At the same time, the circular guide groove of the upper guide roller and the threaded twisting groove of the lower twisting roller play key roles in guiding the yarn and enhancing the twisting effect, respectively, thereby improving the yarn twisting quality.

[0020] Fourth, this utility model increases the flexibility of adjusting the position of the yarn guiding and twisting mechanism by using the universal wheel at the bottom of the fixed frame in conjunction with the bearing and the rotating shaft, which can meet the needs of different spinning processes and operations. The locking device between the fixed frame and the connecting block can ensure stable connection and ensure reliable operation of the yarn guiding and twisting process. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] like Figures 1-8 As shown, this utility model provides a technical solution: a yarn guiding and twisting device for a spinning machine, comprising a support column 1 and a yarn 5. A base 2 is fixed on the support column 1, and a fixing bolt 3 is provided below the support column 1. Through the fixing bolt 3 and the support column 1, the entire device can be stably fixed to a designated position. This stable fixing method can effectively prevent the device from shaking or shifting during operation, providing a guarantee for the stable operation of spinning work, thereby improving spinning quality and efficiency.

[0032] A fixed plate 12 is provided on the base 2. Positioning holes 14 are evenly opened on the surface of the fixed plate 12. Positioning rods 15 are inserted into the positioning holes 14. The surface of the positioning rods 15 overlaps with the surface of the fixed frame 10. A bearing 13 is embedded in the fixed plate 12. A rotating shaft 16 is provided inside the bearing 13. The fixed frame 10 is fixed on the surface of the rotating shaft 16. During operation, the fixed frame 10 can be rotated by the bearing 13 and the rotating shaft 16, which in turn drives the yarn guiding mechanism 4 and the twisting mechanism 6 connected to the fixed frame 10 to rotate on the base 2. When the rotation reaches the appropriate position, the positioning rods 15 in the fixed plate 12 limit the position of the fixed frame 10. This design allows the position of the yarn guiding mechanism and the twisting mechanism 6 to be flexibly adjusted. On the one hand, the direction of the yarn 5 passing through the yarn guiding mechanism 4 and the twisting mechanism 6 can be changed, making it convenient for the operator to collect the twisted yarn 5 at different positions later, thus improving the convenience of operation. On the other hand, by adjusting the direction of the yarn 5, the tension distribution of the yarn 5 can also be optimized, reducing the friction and damage of the yarn 5 during the transmission process and improving the quality of the yarn 5.

[0033] The fixed frame 10 is connected to the connecting block 9 via a vibration assembly 8. The vibration assembly 8 includes a damper 82 fixed on the fixed frame 10, and a spring 81 is sleeved on the surface of the damper 82. The ends of the damper 82 and the spring 81 are fixedly connected to the connecting block 9. When the device is running, the vibration assembly 8 can effectively buffer and absorb the generated vibration, reduce the impact of vibration on the yarn guiding and twisting process, make the yarn 5 more stable during transmission and processing, reduce the probability of yarn breakage, and further improve the stability and quality of spinning.

[0034] The fixed frame 10 and the connecting block 9 are fixed with pins 18 on their sides, and are movably connected to the yarn guiding mechanism 4 and the twisting mechanism 6 respectively through the pins 18. The yarn guiding mechanism 4 consists of an upper guide roller 42 and a lower guide roller 41. The upper guide roller 42 and the lower guide roller 41 have pin holes 17 at both ends. The upper guide roller 42 has evenly distributed circular guide grooves 43 on its surface. The twisting mechanism 6 includes an upper twisting roller 62 and a lower twisting roller 61. The upper twisting roller 62 and the lower twisting roller 61 have pin holes 17 at both ends. The lower twisting roller 61 has threaded twisting grooves 63 on its surface. During operation, the yarn 5 first passes through the yarn guiding mechanism 4. The circular guide grooves 43 of the upper guide roller 42 can better guide the yarn 5 and make it pass through the yarn guiding mechanism 4 in an orderly manner. Then, the yarn 5 enters the twisting mechanism 6. The threaded twisting grooves 63 of the lower twisting roller 61 enhance the twisting effect on the yarn 5 and improve the twisting quality of the yarn 5.

[0035] The fixed frame 10 is movably connected to the lower guide roller 41 in the yarn guiding mechanism 4 and the lower twisting roller 61 in the twisting mechanism 6 via pins 18. The connecting block 9 is movably connected to the upper guide roller 42 in the yarn guiding mechanism 4 and the upper twisting roller 62 in the twisting mechanism 6 via pins 18. This movable connection via pins 18 not only facilitates the installation and disassembly of the yarn guiding mechanism 4 and the twisting mechanism 6, making equipment maintenance and parts replacement easier and reducing equipment maintenance costs and downtime, but also ensures that each mechanism operates in coordination during operation. The connecting blocks 9 are connected by a locking device 7. The bottom of the fixed frame 10 is fixed with a caster wheel 11. The caster wheel 11 can drive the fixed frame 10 to rotate on the base 2. The caster wheel 11, together with the rotation function of the bearing 13 and the rotating shaft 16, increases the mobility of the fixed frame 10, so that the yarn guiding and twisting mechanism 6 can be adjusted in a wider range, further meeting the needs of different spinning processes and operations. At the same time, the locking device 7 ensures the stability of the connection between the fixed frame 10 and the connecting blocks 9, ensuring that the yarn guiding and twisting process is carried out reliably.
