Description

Technical Field

[0001] The present application relates to the technical field of textile production, and in particular to a yarn tensioning device for highly elastic fabrics. Background Art

[0002] High elastic fabric is a common clothing fabric in our lives, and its main components are nylon-spandex elastic fabric and polyester elastic fabric. As the name suggests, high elastic fabric is a fabric material with elasticity, so a reliable and stable tensioning technology is needed to adjust the tension of the yarn during the weaving process.

[0003] The Chinese patent announcement number is CN209889984U, and the announcement date is January 3, 2020. The name of the invention is a tensioning device for high-elasticity and low-retraction yarn. The application discloses that the tensioning device includes a mounting plate, and the mounting plate is provided with an adjustment device. The adjustment device includes a housing, a threaded rod rotatably arranged on the housing, and a translation block threaded through the threaded rod, and a tensioning wheel is fixedly arranged on the translation block. A circular plate is fixed at the end of the threaded rod, and a rotating handle is fixed on the circular plate. Rotating the rotating handle can drive the threaded rod to rotate, thereby driving the tensioning wheel to move back and forth to effectively adjust the tensioning force.

[0004] In the above-mentioned related technologies, the tension adjustment needs to be done by manually rotating the handle, so the tension device in the prior art is suitable for pre-tension adjustment before weaving starts, or for manual observation and manual adjustment during the weaving process. Therefore, during the weaving process, manual observation or adjustment may not be timely, resulting in poor yarn tension and affecting the final yarn forming effect. Utility Model Content

[0005] In order to improve the problem that the yarn tension is not good and the final yarn forming effect is affected due to untimely human observation or adjustment during the weaving process, the present application provides a yarn tensioning device for high-elastic cloth.

[0006] The present application provides a yarn tensioning device for a high elastic fabric, which adopts the following technical solution:

[0007] A yarn tensioning device for highly elastic cloth comprises a frame, the frame is provided with a tensioning wheel for yarn to pass around and a driving assembly for driving the tensioning wheel to move, the moving direction of the driving assembly is not parallel to the yarn direction, a tension detection unit is provided on the moving end of the driving assembly, the tensioning wheel is fixedly arranged at the output end of the tension detection unit; a control panel is provided on the frame, and the tension detection unit and the driving assembly are both electrically connected to the control panel.

[0008] By adopting the above technical solution, the tension wheel can be given a pressure when the yarn is wound around the tension wheel, so that the tension detection unit can detect the pressure fed back by the tension wheel to reflect the tension of the yarn. When the control panel detects that the tension of the yarn exceeds the set range, it can control the drive component to drive the tension wheel to move, so as to adjust the tension of the yarn during the weaving process, and improve the problem of poor yarn tension due to untimely human observation or adjustment during the weaving process, which affects the final shaping effect of the yarn.

[0009] Optionally, a mounting frame is fixedly provided on the frame, and the number of the drive components is set to be several, the number of the drive components corresponds to the number of yarns one by one, each yarn can pass around the tensioning wheel corresponding to the corresponding drive component, and the several drive components and the several tension detection units are electrically connected to the control panel.

[0010] By adopting the above technical solution, the tension of each yarn can be adjusted individually to improve the accuracy of tension control.

[0011] Optionally, the driving assembly includes a connecting seat connected to the mounting frame, a threaded rod is rotatably connected to the connecting seat, the threaded rod passes through and is provided with a moving block, the moving block is slidably connected to the connecting seat along the axis direction of the threaded rod, and the tension detection unit is fixedly set on the moving block.

[0012] By adopting the above technical solution, rotating the threaded rod can drive the moving block to move back and forth, thereby driving the tensioning wheel on the moving block to move. After the tensioning wheel moves, the force exerted by the tensioning wheel on the yarn will also change, thereby adjusting the tension of the yarn.

[0013] Optionally, a worm gear is fixedly provided at the end of the threaded rod, a drive motor is fixedly provided on the connecting seat, a worm is coaxially fixedly connected to the output shaft of the drive motor, the worm and the worm gear are meshed with each other, and the drive motor is electrically connected to the control panel.

[0014] By adopting the above technical solution, the control panel can control the driving motor to rotate, thereby driving the worm to rotate, and then driving the worm wheel to rotate to realize the rotation of the threaded rod. In this adjustment process, the characteristic of the worm gear transmission is relatively large, that is, the driving motor controls the worm to rotate multiple times before driving the worm wheel to rotate one circle, thereby realizing more precise control of the rotation of the threaded rod.

[0015] Optionally, two support rods are fixedly provided on the moving block, and the two support rods are respectively located on both sides of the tension detection unit, and support wheels for stretching the yarn are rotatably provided at the ends of the support rods away from the moving block.

[0016] By adopting the above technical solution, the support wheel is used to control the direction of the section of yarn passing through the tensioning wheel, so that no matter where the tensioning wheel is located, the angle of the yarn when passing through the tensioning wheel is consistent, which is conducive to more accurate detection of the yarn tension by the tensioning wheel.

[0017] Optionally, the support rods are all arranged to be inclined, and the inclination direction is from the connecting seat to the tensioning wheel and gradually away from the tensioning wheel.

[0018] By adopting the above technical solution, the supporting wheel can be kept as far away from the moving block as possible, thereby reducing the probability of the yarn touching the connecting seat or the moving block during operation.

[0019] Optionally, two connecting rods are fixedly provided on the connecting seat, and the two connecting rods are located on both sides of the two supporting rods. Guide wheels for guiding the direction of the yarn are rotatably provided on the side walls of the connecting rods away from the connecting seat.

[0020] By adopting the above technical solution, the yarn direction is regulated by the guide wheel, so as to increase the contact area between the yarn and the support wheel as much as possible. Therefore, even if the yarn direction becomes smoother after the tensioning wheel moves, the yarn and the support wheel can maintain contact, thereby keeping the angle of the yarn consistent when passing through the tensioning wheel.

[0021] Optionally, a side wall of the movable block facing the tensioning wheel is provided with a clearance groove, the extension direction of the clearance groove is parallel to the axial direction of the threaded rod, and the threaded rod is inserted into the clearance groove.

[0022] By adopting the above technical solution, the opening of the give way groove is utilized to increase the moving path of the moving block. On the other hand, the volume of the moving block can be reduced as much as possible while ensuring the moving path, thereby reducing the impact of the moving block volume on the yarn running process.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the control panel detects that the pressure fed back by the tension detection unit at the tension wheel exceeds the set range, it can control the drive assembly to drive the tension wheel to move, so as to adjust the tension of the yarn during the weaving process, and improve the problem of poor yarn tension due to untimely human observation or adjustment during the weaving process, which affects the final forming effect of the yarn;

[0025] 2. The yarn can be wound around the tension wheel at a fixed angle, which helps the tension detection unit to detect the tension more accurately. BRIEF DESCRIPTION OF THE DRAWINGS

During the weaving process, the yarn continuously passes through the tensioning wheel 5, and the tension detection unit 4 can continuously monitor the yarn tension. When the control panel 6 detects that the change in yarn tension exceeds a preset value, the drive motor 308 can be controlled to rotate, driving the threaded rod 303 to rotate, thereby driving the position of the moving block 305 and the tensioning wheel 5 to change, thereby achieving the tension adjustment of the yarn.
