Description

Technical Field

[0001] This utility model relates to the field of rapid positioning technology for yarn guide hooks, specifically a rapid positioning device for yarn guide hooks. Background Technology

[0002] In the ring spinning process of the textile industry, the positioning accuracy of the yarn guide hook plays a decisive role in yarn quality and production efficiency. However, the current positioning methods of the yarn guide hook used in the industry have many drawbacks. In the past, the positioning of the yarn guide hook mostly relied on manual adjustment, which requires extremely high skills and experience from workers. Different workers have different operating techniques and proficiency, making it difficult to control positioning errors. Even a slight deviation in the position of the yarn guide hook will result in uneven stress on the yarn during twisting and winding, leading to quality problems such as uneven yarn thickness and excessive fuzz. This directly affects the appearance and performance of the finished fabric and reduces the product's market competitiveness. For example, when producing yarn for high-end fabrics, the defect rate may be as high as 15%-20% due to inaccurate positioning of the yarn guide hook, resulting in a large amount of raw material waste and increased costs.

[0003] Meanwhile, manual positioning is cumbersome, and each adjustment takes a lot of time. In order to meet the diversified market demand, textile companies frequently change yarn varieties and production processes. Each change requires repositioning the yarn guide hook, which greatly increases equipment downtime and severely reduces production efficiency. According to statistics, manual positioning results in an average of 2-3 hours of equipment downtime per day, which greatly affects the company's production capacity and increases production costs.

[0004] Existing simple positioning aids are limited in function and can only make rough position adjustments. They cannot achieve precise positioning with automation and intelligence. In the modern textile industry, which pursues high-speed, high-efficiency, and high-quality production, these tools cannot monitor and adjust the position of the yarn guide hook in real time and are difficult to adapt to complex and ever-changing production environments. With the continuous advancement of textile technology and the emergence of new spinning equipment, higher requirements are placed on the automation and intelligence level of the yarn guide hook positioning device. Traditional positioning methods and simple aids can no longer meet the needs of industry development.

[0005] Traditional positioning methods rely on frequent manual adjustments, which can easily damage the yarn guide hook and related components due to improper operation, increasing the frequency and difficulty of equipment maintenance. To address these issues, we provide a quick positioning device for the yarn guide hook. Utility Model Content

[0027] 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.

[0028] like Figure 1-7 As shown, this utility model provides a technical solution: a quick positioning device for a yarn guide hook, including a connecting plate 1 and a controller 22. A straight rail 2 is horizontally arranged on the connecting plate 1. The straight rail 2 provides a stable guide for the movement of the yarn guide hook 10, ensuring that the yarn guide hook 10 can move accurately along a predetermined direction, avoiding deviation during the positioning process, thereby improving the positioning accuracy, ensuring the stability of the yarn during the guiding process, reducing yarn shaking and friction, and improving the quality of the yarn. A moving motor 4 is arranged at one end of the straight rail 2, and a screw is arranged in the sliding groove 6 opened inside the straight rail 2. The threaded rod 15 has one end connected to the output of the moving motor 4. A movable block 7 is fixed to the surface of the threaded rod 15 by a threaded block 14. The moving motor 4 drives the threaded rod 15 to rotate, which in turn drives the movable block 7 to move. This driving method makes the movement of the yarn guide hook 10 more precise and efficient. Compared with the traditional manual adjustment method, it greatly shortens the positioning time of the yarn guide hook 10 and improves production efficiency. For example, in production scenarios where the position of the yarn guide hook 10 needs to be changed frequently, positioning can be completed quickly, reducing equipment downtime and increasing output per unit time.

[0029] The movable block 7 has a rotating groove 21 for the yarn guide hook 10 to rotate. The yarn guide hook 10 is set in the rotating groove 21. A rotary motor 9 is fixed to the side of the movable block 7 by a support plate 8. The output shaft of the rotary motor 9 passes through a rotating hole 18 in the movable block 7. A rotating component 19 passes through the rotating hole 18 and passes through the rotating groove 21 in the movable block 7. The rotating component 19 is engaged with the yarn guide hook 10 and the output shaft of the rotary motor 9 through a slot 20. The rotary motor 9 can precisely control the rotation angle of the yarn guide hook 10. According to different spinning process requirements, the angle of the yarn guide hook 10 can be quickly adjusted to ensure that the yarn can enter at the optimal angle during twisting, improve the twisting quality of the yarn, make the yarn structure more compact and uniform, and enhance the strength and stability of the yarn.

[0030] A sensor receiver 13 is installed on the surface of the straight rail 2 at the bottom of the movable block 7. A corresponding sensor transmitter 5 is installed on the surface of the connecting plate 1. Through the cooperation of the sensor receiver 13 and the sensor transmitter 5, the position information of the movable block 7 can be monitored in real time and fed back to the controller 22. This allows the controller 22 to accurately control the movement of the moving motor 4 and the rotating motor 9 according to the actual position of the movable block 7, further improving the positioning accuracy and stability of the yarn guide hook 10. Even if there are minor vibrations or other interference factors during the operation of the equipment, the position of the yarn guide hook 10 can be adjusted in time to ensure that the yarn guidance is always in the best state.

[0031] Specifically, the straight rail 2 is equipped with a bearing 16, and the rotating shaft 17 is also equipped with a rotating shaft 17, which is fixed to the other end of the threaded rod 15. The bearing 16 reduces the friction when the threaded rod 15 rotates, reduces energy loss, and improves the operating efficiency of the equipment. At the same time, it makes the rotation of the threaded rod 15 smoother, avoids vibration caused by friction from affecting the positioning accuracy of the yarn guide hook 10, extends the service life of the equipment, and reduces the maintenance cost of the equipment.

[0032] Specifically, one end of the connecting plate 1 is provided with a placement groove 12, and the moving motor 4 is placed in the placement groove 12. The placement groove 12 provides a stable installation position for the moving motor 4, protecting the moving motor 4 from external collisions and interference, and ensuring its normal operation. At the same time, it facilitates the installation, disassembly, and maintenance of the moving motor 4. When the moving motor 4 malfunctions, it can be repaired or replaced more easily, reducing equipment maintenance time and improving production continuity.

[0033] Specifically, the surface of the straight rail 2 is provided with a positioning block 11, and the positioning block 11 is fixed to the connecting plate 1 by a positioning bolt 3. The connecting plate 1 is fixed to the key of the external ring spinning machine by the positioning bolt 3. This fixing method allows the positioning device to be stably installed on the ring spinning machine, ensuring that the positioning device will not shift or shake during equipment operation, and ensuring the accuracy and stability of the positioning of the yarn guide hook 10. Moreover, the positioning bolt 3 facilitates the installation and disassembly of the positioning device, facilitates equipment debugging and maintenance, improves the versatility of the equipment, and can be applied to different models of ring spinning machines.

[0034] Specifically, the controller 22 includes a processing unit 221, a storage module 222, and an execution module 223. The controller 22 is connected to the moving motor 4, the rotating motor 9, the sensor transmitter 5, and the sensor receiver 13 via wires. The processing unit 221 of the controller 22 can quickly process the position information fed back by the sensor receiver 13 and, according to preset programs and parameters, issue instructions to the execution module 223 to precisely control the actions of the moving motor 4 and the rotating motor 9. The storage module 222 can store the positioning parameters of the yarn guide hook 10 required for different spinning processes, allowing operators to quickly recall them according to actual production needs, improving production flexibility and efficiency. Simultaneously, the controller 22 achieves automated control of the entire positioning process, reducing errors from manual operation and improving the accuracy and consistency of positioning.

[0035] Working principle: First, the connecting plate 1 is fixed to the key of the external ring spinning machine by the positioning bolt 3. The positioning block 11 on the surface of the straight rail 2 is also fixed to the connecting plate 1 by the positioning bolt 3 to ensure that the entire device is stably installed on the ring spinning machine. The moving motor 4 is placed in the placement groove 12 at one end of the connecting plate 1. The bearing 16 in the straight rail 2 cooperates with the rotating shaft 17 to enable the threaded rod 15 to rotate stably.

[0036] According to the requirements of the spinning process, the operator inputs parameters such as the target position and rotation angle of the yarn guide hook 10 into the controller 22. The storage module 222 of the controller 22 stores the positioning parameters corresponding to various spinning processes in advance, and can also be directly selected and called. The processing unit 221 receives these instruction information and performs analysis and processing.

[0037] During horizontal positioning: Processing unit 221 sends a control signal to execution module 223, which then controls the movement motor 4 to start. The output shaft of movement motor 4 drives threaded rod 15 to rotate. Since threaded rod 15 and threaded block 14 are connected by threads, and threaded block 14 is fixed on movable block 7, the rotation of threaded rod 15 drives movable block 7 to move linearly along the axis of threaded rod 15 on straight rail 2. During this process, straight rail 2 provides precise guidance for the movement of movable block 7, ensuring smooth movement. Sensor receiver 13 on the surface of straight rail 2 at the bottom of movable block 7 and sensor transmitter 5 on the surface of connecting plate 1 work together to monitor the position of movable block 7 in real time. Sensor transmitter 5 continuously transmits signals, and sensor receiver 13 receives the signals and feeds back the position information of movable block 7 to controller 22. When the position information fed back by sensor receiver 13 indicates that movable block 7 has reached the target horizontal position, processing unit 221 controls execution module 223 to stop movement motor 4, completing the horizontal positioning of yarn guide hook 10.

[0038] During angle adjustment and positioning: After the yarn guide hook 10 is horizontally positioned, if it is necessary to adjust the angle of the yarn guide hook 10, the processing unit 221 sends an instruction to the execution module 223 again to control the rotary motor 9 to start. The output shaft of the rotary motor 9 drives the rotating component 19 to rotate. The rotating component 19 is connected to the yarn guide hook 10 through the slot 20, thereby driving the yarn guide hook 10 to rotate in the rotation groove 21 of the movable block 7, realizing the adjustment of the angle of the yarn guide hook 10. The rotation angle of the rotary motor 9 is precisely controlled by the controller 22 to ensure that the yarn guide hook 10 rotates to the target angle.

[0039] Positioning calibration and fine-tuning: After the yarn guide hook 10 completes horizontal movement and angle adjustment, the sensor receiver 13 continuously monitors the position information of the moving block 7. If the position of the yarn guide hook 10 deviates slightly due to factors such as equipment vibration, the sensor receiver 13 will feed back the deviation information to the controller 22. The processing unit 221 controls the moving motor 4 or the rotating motor 9 to make fine adjustments based on the feedback information through the execution module 223, so that the yarn guide hook 10 returns to the accurate target position and ensures the accuracy of positioning.
