Description

Technical Field

[0001] The utility model relates to the technical field of spinning frames, in particular to a traction device for a spinning frame. Background Art

[0002] Spinning frame is a spinning machine that stretches, twists and winds semi-finished roving or sliver into spun yarn in the spinning process. The sliver is stretched and twisted on the roving frame to make roving, the combing machine combs the fiber to make combed sliver, the gill combing machine combines the slivers, and the pin row stretching improves the sliver structure. The roving is further twisted and spun into spun yarn on the ring spinning frame. The spinning frame is the main machine for spinning. The output and quality of spun yarn are a comprehensive reflection of the quality of each process of the spinning process.

[0003] The existing thick yarn needs to be pulled by a traction device. Since the spinning machine needs to process the thick yarn into thin yarn, the thick yarn is wound less times and the force between adjacent cotton strips is smaller, which can easily cause the thick yarn to be broken. If it is pulled too loose, the cotton strips are easy to be tangled together, which will affect the processing efficiency of the thick yarn and the quality of the finished product. Therefore, it is necessary to maintain a relatively stable traction force on the thick yarn during the traction process.

[0004] Therefore, those skilled in the art provide a traction device for a spinning frame to solve the problems raised in the above background technology. Utility Model Content

[0024] The positioning frame 1 is fixedly installed on the spinning frame, and the traction roller 2 is installed on one side of the positioning frame 1. The positioning frame 1 is in a U-shape that opens upward. The yarn passed by the tensioning assembly remains in a tensioned state. The support roller 3 and the support roller 2 4 are not on the same vertical plane. The movable groove 5 is located on the mounting frame. The movable groove 5 can guide the movement of the support roller 3 and the support roller 2 4. The yarn passes through the bottom of the support roller 3 and is wrapped around the top of the support roller 2 4. The yarn is S-shaped and is wrapped around the support roller 3 and the support roller 2 4. The support roller 1 3 and the support roller 2 4 are connected to the positioning frame 1 through elastic parts. When the traction roller 2 pulls the yarn to move, the elastic parts at both ends of the support roller 3 and the support roller 2 4 will be tightened to keep the yarn in a certain tension. Such a setting can prevent the yarn from being broken.

[0025] In one embodiment, specifically, the two ends of the support roller 1 3 and the support roller 2 4 are respectively connected with sliders 6, the slider 6 is slidably connected to the movable groove 5, the elastic member includes a spring 1 7 and a spring 2 8, the spring 1 7 is located between the top of the slider 6 at both ends of the support roller 1 3 and the movable groove 5, the spring 2 8 is located between the bottom of the slider 6 at both ends of the support roller 2 4 and the movable groove 5, the two ends of the support roller 1 3 and the support roller 2 4 are respectively connected to the movable groove 5 through the slider 6, the support roller 1 3 and the support roller 2 4 are rotatably connected with the slider 6, the spring 1 7 can lift the support roller 1 3, and the spring 2 8 can lift the support roller 2 4 to facilitate the movement of the support roller 1 3 and the support roller 2 4.

[0026] Among them, guide roller 1 9 and guide roller 2 10 are installed on the positioning frame 1, the guide roller 1 9 is located obliquely above the support roller 1 3, and the guide roller 2 10 is located obliquely below the support roller 2 4. Guide roller 1 9 and guide roller 2 10 are installed on the positioning frame 1 in parallel with the support roller 1 3, so as to facilitate the guiding of the traction of the yarn.

[0027] On the basis of the above embodiment, specifically, a positioning rod 11 is installed inside the movable groove 5, and the positioning rod 11 is respectively located on the inner side of spring one 7 and the inner side of spring two 8.

[0028] When using a spinning machine to pull the yarn, the yarn is first passed through guide roller 1 9, support roller 1 3, support roller 2 4 and guide roller 2 10 in sequence, and then one end of the yarn is connected to the traction roller 2, and then the traction roller 2 is rotated. The rotation of the traction roller 2 can drive the yarn to move. Since spring 1 7 and spring 2 8 are arranged between support roller 1 3 and support roller 2 4, the yarn can be kept in a tensioned state. When the tension of the traction roller 2 is too large, support roller 1 3 and support roller 2 4 will approach each other by a certain distance. When the tension of the traction roller 2 is reduced, support roller 1 3 and support roller 2 4 will move away from each other by a certain distance. In this process, support roller 1 3 and support roller 2 4 can keep the tension of the yarn within a certain range to prevent the yarn from being broken.
