Abstract
Description
Technical Field
[0001] This utility model relates to the field of air-jet loom equipment technology, specifically to an air-jet loom cotton fabric tension adjustment device. Background Technology
[0002] The tension regulating device for cotton fabric on an air-jet loom is an important component of the air-jet loom. During the weaving process, the tension of the warp and weft yarns needs to be maintained within a suitable range to ensure the quality and efficiency of the fabric. The tension regulating device maintains the appropriate tension by applying a certain amount of tension to the warp or weft yarns.
[0003] According to the search, the technical point of the tension adjustment device for the air-jet loom disclosed in Chinese Patent No. CN221398252U is that when adjusting the tension of the fixed guide roller on the fabric, the servo motor can drive the adjustment device to be precisely lifted inside the limit slide through the transmission screw, thereby quickly and accurately adjusting the tension height of the fixed guide roller on the fabric.
[0004] However, in existing technologies, the height of the fixed guide roller is generally adjusted by driving the transmission screw to achieve a high tension effect, which results in a slow response when the tension span is large. In order to solve the problem of slow tension response in existing technologies, this application proposes to set up multiple tensioning mechanisms with different spans on a turntable, thereby enabling large-span tension adjustment and improving the response speed. Therefore, a new solution is needed to solve this problem. Utility Model Content

A gear one is mounted on the sleeve, and a gear two meshes with one side of the gear one. A servo motor one is provided at the power end of the gear two and is mounted on the mounting bracket.
[0009] Furthermore, the driving mechanism includes a drive shaft that passes through the turntable and is rotatably connected to the sleeve. A second servo motor is provided at the power end of the drive shaft and is mounted on the sleeve.

During operation, the drive shaft is rotated, and the positions of multiple tension rollers are synchronously adjusted through the cooperation of the first fixed shaft, the second fixed shaft, and the slide plate, thereby achieving tensioning over a small span. The mounting plate is rotated through the cooperation of the first gear, the second gear, and the sleeve, thereby changing the relative positions of the tension rollers and achieving rapid adjustment over a large span, thus improving the tensioning response speed.
[0015] 2.

[0023] Please see Figure 1 , Figure 3 , Figure 4 The present invention relates to a cotton fabric tension adjustment device for an air-jet loom, comprising a mounting frame 1, wherein the device is mounted on a designated device via the mounting frame 1. Mounting plates 2 are provided at both ends of the mounting frame 1, and a rotating assembly is provided between the mounting plates 2 and the mounting frame 1. A turntable 3 is provided in the middle of each of the two mounting plates 2, and a driving mechanism is provided between the two turntables 3. Multiple sliding plates 5 are provided on each of the two turntables 3, with at least two plates 5. The multiple sliding plates 5 are circumferentially distributed around the axis of the turntable 3. A connecting assembly is provided between the sliding plates 5 and the turntable 3. Different sliding plates 5 are connected by a tensioning roller 6 between two opposite sliding plates 5, and an elastic assembly is provided between the tensioning roller 6 and the sliding plates 5.

The first fixed shaft 9 is mounted on the slide plate 5, and the second fixed shaft 10 is mounted on the turntable 3. A connecting plate 11 is provided between the first fixed shaft 9 and the second fixed shaft 10. When the turntable 3 rotates, it drives the second fixed shaft 10 to rotate as well. The second fixed shaft 10 drives one end of the connecting plate 11 to move as well. By changing the rotation direction of the turntable 3, the movement direction of the connecting plate 11 is changed.
[0025] Looking back Figure 3 As shown, the rotating assembly includes a sleeve 15, one end of which is mounted on the mounting plate 2. The sleeve 15 is rotatably mounted on the mounting bracket 1. A gear 16 is mounted on the sleeve 15. A gear 17 meshes with one side of the gear 16. A servo motor is mounted on the power end of the gear 17. The servo motor is mounted on the mounting bracket 1. A brake device is mounted on the rear end of the servo motor. When the motor is de-energized, the brake device will hold the motor shaft to achieve self-locking.
[0026] Combination Figure 1 , Figure 3 As shown, the drive mechanism includes a drive shaft 4, which passes through the turntable 3 and is rotatably connected to the sleeve 15.

[0027] like Figure 2 As shown, the elastic component includes a slider 12, which is slidably mounted on a slide plate 5. The slide plates 5 are connected to each other by a telescopic rod 13. A spring 14 is fitted on the telescopic rod 13.
