Description

Technical Field

[0001] The utility model relates to the field of textile equipment, and more specifically, it relates to a synchronous elastic yarn conveyor with tension adjustment. Background Art

[0002] In the textile industry, the conveying and tension control of yarn are key factors affecting the quality and production efficiency of textile products. When traditional yarn conveying devices operate at high speeds, they often face problems such as unstable tension, yarn breakage, and wear. To improve the stability and efficiency of yarn conveying, the industry has been continuously innovating and improving technologies. In the existing yarn conveying technologies, the accuracy of tension control is a challenge. Imprecise tension control may lead to yarn quality problems. For example, excessive tension may affect the structure and strength of the yarn.

[0003] Therefore, a new solution is needed to solve this problem. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a synchronous elastic yarn conveyor with tension adjustment.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A synchronous elastic yarn conveyor with tension adjustment includes a housing and a tension sensing device. A synchronous pulley is provided inside the housing. A synchronous motor and a human-machine interface for driving the synchronous pulley to rotate are provided outside the housing. The synchronous pulley is provided with an anti-static ceramic spray coating. A Hall sensor for detecting the magnitude of tension is provided inside the tension sensing device. The Hall sensor has a threshold value, and the threshold value of the Hall sensor is set through the human-machine interface. When the yarn tension is greater than the threshold value, the rotation speed of the synchronous pulley increases.

[0006] The utility model is further provided as: The tension sensing device is provided with an elastic hook for clamping the yarn.

[0007] The utility model is further provided as: A pressing bearing and a gas valve device are provided inside the housing. The gas valve device includes an inflation state and a deflation state. When the gas valve device is in the inflation state, the pressing bearing is away from the synchronous pulley. When the gas valve device is in the deflation state, the pressing bearing presses against the synchronous pulley.

[0008] The utility model is further provided as: A limiting rod is provided inside the housing, and the pressing bearing is located between the limiting rod and the synchronous pulley.

[0009] The utility model is further provided as: The threshold value range of the Hall sensor is from 0 to 300.

[0010] The present utility model is further configured such that: on one side of the housing away from the tension sensor, there are provided a yarn breaking device and an alarm. When the yarn tension is greater than the maximum threshold value of the Hall sensor, the yarn breaking device clamps and breaks the yarn, and the alarm gives an alarm.

[0011] The present utility model is further configured such that: the threshold value of the Hall sensor is 120.

[0012] In summary, the present utility model has the following beneficial effects: By using a Hall sensor for tension detection, the tension of the yarn can be monitored in real time, and the threshold value can be set through a human-machine interface to achieve precise control. This helps to reduce the problems of affecting the yarn structure and strength due to excessive tension, improve product quality. When the yarn tension exceeds the set threshold value, the rotational speed of the synchronous pulley will automatically increase, quickly responding to the tension change and maintaining the tension stability. This automatic adjustment mechanism reduces human intervention, improves production efficiency and the stability of the system. The synchronous pulley is provided with an anti-static ceramic spray coating, which helps to reduce the impact of static electricity on the yarn and the production environment, and also plays a protective role for the synchronous pulley, avoiding the generation of pits on the surface of the synchronous pulley, extending the service life of the synchronous pulley, and improving production safety.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments, and are not intended to limit this application.

[0019] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0020] A synchronous elastic yarn conveyor with tension adjustment, as Figure 1 shown, includes a housing 1 and a tension sensing device 2. A synchronous pulley 3 is provided inside the housing 1, and a synchronous motor 4 and a human-machine interface 5 for driving the synchronous pulley 3 to rotate are provided outside the housing 1. By setting the synchronous motor 4 and the human-machine interface 5, an operator can input parameters through the human-machine interface 5, so that the synchronous motor 4 drives the synchronous pulley 3 to reach a specified rotational speed. On the side of the tension sensing device 2 facing away from the housing 1, there is a yarn guide disk. By setting the yarn guide disk, problems such as knotting or winding of the yarn during the tightening process can be prevented, protecting the tension sensing device 2 and ensuring the working efficiency. Further, an anti-static ceramic spray coating is provided on the synchronous pulley 3. The ceramic coating improves the wear resistance of the synchronous pulley 3, extends its service life, reduces the maintenance cost, and the ceramic spray coating has a significant electrostatic dissipation effect, which can eliminate the damaging effect of static electricity and reduce the damage caused by static electricity.

[0021] A Hall sensor 6 for detecting the magnitude of the tension is provided inside the tension sensing device 2. The Hall sensor 6 has a threshold value, and the threshold value of the Hall sensor 6 is set through the human-machine interface 5. The threshold range of the Hall sensor 6 is from 0 to 300. Specifically, in this solution, when the threshold value of the Hall sensor 6 is 120, the quality of the produced yarn is the best. When the yarn tension is greater than the threshold value, the rotational speed of the synchronous pulley 3 increases. By using the Hall sensor 6 for tension detection, the magnitude of the yarn tension can be monitored in real time, and the threshold value can be set through the human-machine interface 5 to achieve precise control. This helps to reduce the problem that the yarn structure and strength are affected due to excessive tension and improve the product quality. When the yarn tension exceeds the set threshold value, the rotational speed of the synchronous pulley 3 will automatically increase, quickly responding to the tension change and keeping the tension stable.

[0022] Furthermore, an elastic hook 7 for clamping the yarn is provided on the tension sensing device 2. Specifically, the elastic hook 7 is made of ceramic, and there is an opening on the elastic hook 7. Magnetic blocks are provided on both the outer wall of the elastic hook 7 and the tension sensing device 2. The elastic hook 7 and the tension sensing device 2 are adsorbed to each other through the magnetic blocks to clamp the yarn. By setting the elastic hook 7, non-contact clamping of the yarn can be achieved, avoiding damage to the yarn that may be caused by traditional mechanical clamping. Moreover, the elastic hook 7 can be quickly adjusted according to the tension requirements of the yarn to adapt to yarns of different thicknesses and materials. The design of the elastic hook 7 can ensure the stability of the yarn during the processing.

[0023] A pressing bearing 8 and a valve device 9 are provided in the housing 1. The valve device 9 includes an inflation state and a deflation state. When the valve device 9 is in the inflation state, the pressing bearing 8 is away from the synchronous pulley 3. When the valve device 9 is in the deflation state, the pressing bearing 8 presses against the synchronous pulley 3. Through the inflation and deflation states of the valve device 9, the contact between the pressing bearing 8 and the synchronous pulley 3 can be dynamically adjusted, so as to achieve precise control of the transmission system. When the synchronous pulley 3 does not need to be pressed, the pressing bearing 8 being away from the synchronous pulley 3 can reduce unnecessary wear and extend the service life of the bearing and the synchronous pulley 3. When the synchronous pulley 3 needs to be pressed, the pressing bearing 8 can quickly press against the synchronous pulley 3 to ensure the stability and efficiency of the transmission system. At the same time, by controlling the contact state of the pressing bearing 8 through the valve device 9, the maintenance and adjustment process is simplified, the maintenance cost is reduced. Furthermore, a limiting rod 10 is provided in the housing 1, and the pressing bearing 8 is between the limiting rod 10 and the synchronous pulley 3. Due to the limiting effect of the limiting rod 10, the pressing bearing 8 moves more stably under the control of the valve device 9, reducing displacement caused by vibration or impact, thereby improving the stability of the entire transmission system.

[0024] A yarn breaking device 11 and an alarm 12 are provided on one side of the housing 1 away from the tension sensor. When the yarn tension is greater than the maximum threshold value of the Hall sensor 6, the yarn breaking device clamps and breaks the yarn, and the alarm 12 gives an alarm. When the yarn tension exceeds the maximum threshold value of the Hall sensor 6, the yarn breaking device 11 can quickly clamp and break the yarn, avoiding yarn breakage or equipment damage caused by excessive tension. The timely alarm function of the alarm 12 can remind the operator or the automatic control system to take measures, such as stopping the machine operation or performing other necessary interventions, thus ensuring production safety. At the same time, by automatically clamping and breaking the yarn and giving an alarm, the waste of raw materials caused by yarn breakage can be reduced, and the production efficiency can be improved.

[0025] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
