Description

Technical Field

[0001] This invention relates to the field of textile yarn and fabric tension control technology, specifically an intelligent textile tensioner. Background Technology

[0002] In the entire textile industry process, tension control of yarn and fabric is a core element determining product quality. From yarn formation during spinning to fabric setting in the dyeing and finishing stage, tension fluctuations exceeding ±5% can lead to problems such as yarn breakage, fabric wrinkling, or uneven dyeing. Traditional manual adjustment relies on operational experience, and tension stability can only reach ±10%.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] The technical problem to be solved by this invention is to overcome the above-mentioned technical defects and provide an intelligent textile tensioner. Through a tension sensor closed-loop control system constructed by an electromagnetic spring, the tension fluctuation can be precisely controlled within 0.1 grams, thereby increasing the yield rate of high-grade fabrics from 70% to over 95%.

[0005] To solve the above problems, the technical solution of the present invention is: an intelligent textile tensioner, including a housing, a wire inlet at the upper end of the housing, and a motor at the upper end of the interior of the housing; A driving wheel assembly and a driven wheel assembly are provided, wherein the driving wheel assembly and the driven wheel assembly are disposed at the output end of the motor, and the driving wheel assembly is connected to the output end of the motor; A pressure arm assembly, wherein the pressure arm assembly is disposed inside the housing; An electromagnetic spring is disposed on the lower side of the pressure arm assembly; A tension bar assembly, wherein the tension bar assembly is disposed on one side of the electromagnetic spring.

[0006] Preferably, the drive wheel assembly includes: The motor output end is connected to the drive gear. One end of the drive gear is provided with a connecting shaft, and a drive wheel is sleeved on the surface of the connecting shaft. One end of the drive wheel is provided with a limiting plate.

[0007] Preferably, the driven wheel assembly includes: Driven gear, which meshes with driving gear, has a rotating shaft inside, which is rotatably connected to housing, and a driven wheel is sleeved on the surface of the rotating shaft, with a limiting ring at one end of the rotating shaft.

[0008] Preferably, the pressure arm assembly includes a second connecting shaft, which is fixedly connected to the inside of the housing. A torsion spring and a pressure arm are sleeved on the surface of the second connecting shaft, with one end of the torsion spring fixed to the second connecting shaft and the other end fixedly connected to the pressure arm.

[0009] Preferably, the tension bar assembly includes a tension bar, one end of which is rotatably connected to an electromagnetic spring, and the other end of which is provided with a through hole.

[0010] Preferably, the lower end of the housing is provided with a wire guide wheel for winding and connecting the wire, and the wire is wound through the wire inlet, between the driving wheel and the driven wheel, the wire guide wheel and the through hole in sequence.

[0011] The advantages of this invention compared to existing technologies are: In this invention, the yarn is introduced into the gap between the driving and driven wheel assemblies through the inlet. The pressure arm prevents the yarn from slipping to the left or right. The yarn then passes through the electromagnetic spring tension rod assembly via the guide coil and finally enters the flat knitting machine. By comparing the spring deflection angle with the target angle, the speed of the pay-off motor is adjusted in real time to stabilize the spring deflection angle, thereby stabilizing the tension. This textile tension control system, constructed through an electromagnetic spring and a tension sensor closed-loop control system, can precisely control tension fluctuations within 0.1 grams, increasing the yield rate of high-grade fabrics from 70% to over 95%. When the tension is insufficient, the yarn automatically returns to maintain a constant tension. When the tension exceeds the limit, the yarn is actively paid off, with a fast response speed.

[0018] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, an intelligent textile tensioner includes a housing 1 with a yarn inlet 2 at its upper end. A motor 3 is installed inside the upper part of the housing 1. A drive wheel assembly 4 and a driven wheel assembly 5 are located at the output end of the motor 3, with the drive wheel assembly 4 connected to the output end of the motor 3. The drive wheel assembly 4 includes a drive gear 9, and the output end of the motor 3 is connected to the drive gear 9. A connecting shaft 10 is installed at one end of the drive gear 9, and a drive wheel 11 is mounted on the surface of the connecting shaft 10. A limiting plate 12 is installed at one end of the drive wheel 11. The driven wheel assembly 5 includes a driven gear 13, which meshes with the drive gear 9. A rotating shaft 14 is installed inside the driven gear 13 and rotatably connected to the housing 1. A driven wheel 15 is mounted on the surface of the rotating shaft 14, and a limiting ring 16 is installed at one end of the rotating shaft 14.

[0020] When the motor 3 starts, it drives the drive gear 9 to rotate, which in turn drives the drive wheel 11 to rotate through the connecting shaft 10. The rotation of the drive gear 9 drives the meshing driven gear 13 to rotate, which in turn drives the driven wheel 15 to rotate.

[0021] An electromagnetic spring 7 is located on the lower side of the pressure arm assembly 6; a tension rod assembly 8 is located on one side of the electromagnetic spring 7. The tension rod assembly 8 includes a tension rod 20, one end of which is rotatably connected to the electromagnetic spring 7, and the other end of which has a through hole 21. A wire guide wheel 22 for winding is installed on one side of the lower end of the housing 1. The winding passes sequentially through the wire inlet 2, between the driving wheel 11 and the driven wheel 15, the wire guide wheel 22, and the through hole 21.

[0022] The pressure arm assembly 6 is located inside the housing 1. The pressure arm assembly 6 includes a connecting shaft 2 17, which is fixedly connected to the inside of the housing 1. A torsion spring 18 and a pressure arm 19 are mounted on the surface of the connecting shaft 2 17. One end of the torsion spring 18 is fixed to the connecting shaft 2 17 and the other end is fixedly connected to the pressure arm 19, which can prevent the yarn from moving left and right.

[0023] Working Principle: The raw yarn used in textiles is released from the upper bobbin and enters the device through the inlet 2. The driving wheel 11 and driven wheel 15 generate a speed difference with the linear velocity, which is then transmitted to the textile actuator via the electromagnetic spring 7 and tension rod 20 to generate counter-tension. Tension adjustment is controlled by the motor 3 to generate a speed difference between the driving wheel 11 and driven wheel 15 and the linear velocity. Tension feedback is achieved by the position of the tension rod 20 of the electromagnetic spring 7. Under constant current, the tension is proportional to the position of the tension rod 20. By real-time acquisition of the position of the tension rod 20 and the constant current value, the real-time tension value can be calculated. Closed-loop constant tension control: When the tension is greater than the target tension, the servo motor 3 accelerates; when the tension is less than the target tension, the servo motor 3 decelerates; when the tension equals the target tension, the servo motor 3 maintains a constant speed.

[0024] Tension setting: Different constant current values ​​can be used to set different spring force coefficients of electromagnetic spring 7, and the tension generated by its tension rod 20 is proportional to the current.
