Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and more specifically, to a cotton yarn spindle tensioning mechanism. Background Technology

[0002] During the spinning process, a certain tension is applied to the cotton yarn through specific mechanisms or devices to maintain the stability and uniformity of the yarn during processing. Appropriate tension can reduce the stretching and shrinkage of the yarn, thereby ensuring the uniformity and stability of the yarn. This is very important for producing high-quality textiles. By automatically adjusting the tension, production interruptions caused by yarn breakage can be reduced, thereby improving production efficiency.

[0003] A search revealed that Chinese patent CN220223061U discloses a cotton yarn tensioning device. The device uses a drive gear to rotate a turntable counterclockwise, allowing the cotton yarn to pass between two grooved wheels. The drive gear then rotates the turntable clockwise, tightening the yarn between the two grooved wheels. The tightening process is convenient, and the tensioning angle of the two grooved wheels on the yarn can be adjusted to achieve the optimal tension.

[0004] When the above-mentioned tensioning device is in use, the yarn is stretched between two grooved wheels, and the tensioning angle of the two grooved wheels on the yarn can be adjusted. At the same time, one end of the yarn is pulled by the processing equipment. However, it is inconvenient to adjust the distance between the two grooved wheels. When the yarn is thick or thin, the fixed grooved wheel spacing cannot provide the best tensioning effect, thus affecting the quality of the yarn. Its application range is relatively small. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cotton yarn spindle tensioning mechanism, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cotton yarn spindle tensioning mechanism, comprising a support frame, two mounting frames, and two grooved wheels. The two mounting frames and two grooved wheels are located on the front side of the support frame, and the front and rear ends of the two grooved wheels are movably connected to the two mounting frames via bearings. A connecting frame is provided between the two mounting frames, and a moving component is provided on the connecting frame. The moving component includes a first gear rod, a toothed plate, a side plate, a slide rod, and a handle. The front and rear ends of the first gear rod are movably connected to the connecting frame via bearings. The toothed plate meshes with the first gear rod. One side of the side plate is fixedly connected to the toothed plate and movably sleeved on the slide rod. Both ends of the slide rod are fixedly connected to the connecting frame. The rear side of the handle is fixedly connected to the first gear rod. The number of toothed plates, side plates, and slide rods are all two.

[0007] Furthermore, a threaded insert is movably sleeved on the handle, and the threaded insert is threadedly connected to the front side of the connecting frame.

[0008] As can be seen, in the above technical solution, rotating the threaded rod and letting it pass through the front side of the handle and the connecting frame fixes the slide rod to the connecting frame, thus limiting the slide rod.

[0009] Furthermore, limit frames are fixedly connected to the front side of the support frame and at the top and bottom of the connecting frame, and buffer pads are fixedly connected to the opposing sides of the two limit frames by bolts.

[0010] It can be seen that the above technical solution is designed to facilitate elastic support for the connecting frame.

[0011] Furthermore, a rotating assembly is provided on the rear side of the support frame, and the rotating assembly includes a cross column, a gear sleeve, a second gear rod and a self-locking motor. The rotating assembly serves to facilitate the rotation of the two mounting frames.

[0012] Furthermore, the front end of the cross column is fixedly connected to the connecting frame, and the cross column and the support frame are movably connected by a bearing. The front side of the gear sleeve is fixedly connected to the cross column, and the gear sleeve meshes with the second gear rod. The self-locking motor is fixedly installed on the front side of the support frame, and the output shaft end of the self-locking motor is fixedly connected to the second gear rod.

[0013] Furthermore, the self-locking motor has a built-in electromagnetic locking structure, which can prevent the horizontal column from rotating.

[0014] Furthermore, a base is fixedly connected to the bottom end of the support frame, wherein the base can facilitate the support and fixation of the support frame.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model can drive the first gear rod to rotate by turning the handle, thereby driving the two mounting frames to move in opposite directions, and then driving the two grooved wheels to move in opposite directions. Similarly, reversing the handle will cause the two grooved wheels to move towards each other. The distance between the two grooved wheels can be adjusted according to the thickness of the yarn, and finally the yarn is tightened in the two grooved wheels. The operation is simple, the distance between the two grooved wheels can be easily adjusted, and the application range is wide.

[0017] 2. This utility model uses a self-locking motor to drive the second gear rod to rotate, which in turn drives the gear sleeve and the cross column to rotate, and then drives the connecting frame and the two grooved wheels to rotate. The tilt angle of the two grooved wheels can be adjusted as needed. When the connecting frame comes into contact with the buffer pad, the buffer pad can provide elastic support for the connecting frame. The fixing between the limit frame and the buffer pad can be released by bolts, and the buffer pad can be disassembled and replaced. The structure is simple and easy to use.

The rear side of the handle 505 is fixedly connected to the first gear rod 501, and there are two toothed plates 502, two side plates 503, and two slide rods 504.

[0027] Furthermore, a threaded insert 506 is movably sleeved on the handle 505, and the threaded insert 506 is threadedly connected to the front side of the connecting frame 4.

[0028] Furthermore, limit frames 7 are fixedly connected to the front side of the support frame 1 at the top and bottom of the connecting frame 4.

The rotating assembly 6 includes a horizontal column 601, a gear sleeve 602, a second gear rod 603, and a self-locking motor 604. The rotating assembly 6 facilitates the rotation of the two mounting frames 2.
