[0002] A combing machine is a machine used to implement the combing process in the spinning process. Its main functions are to remove shorter fibers, remove tangled particles (neps, hair particles, grass scraps, cocoon skins, etc.) in the fibers, and further straighten and parallelize the fibers, and finally make combed slivers with relatively uniform thickness.

The limiting frame 8 made of metal material has higher strength, is not easily deformed and damaged after being subjected to force, and is more durable. The inner wall of the limiting frame 8 is slidably connected to a limiting slider 9, and the limiting slider There are multiple blocks 9, and multiple limit sliders 9 are all located inside the limit frame 8, which are used to assist the adjustment roller 11 in lifting and moving, thereby improving the movement stability. An adjustment detection mechanism is arranged inside the limit slider 9, and the adjustment detection mechanism consists of a through-axis tension sensor 10 and an adjustment roller 11. The through-axis tension sensor 10 is fixedly connected to the inner wall of the limit slider 9, and the adjustment roller 11 is rotatably connected to the inner wall of the through-axis tension sensor 10, which is used to detect the current tension of the fiber, so as to facilitate driving the fiber to lift and move for tension adjustment. A lifting component is arranged on the front of the limit slider 9, a driving mechanism is arranged on the top surface of the limit frame 8, and an auxiliary component is arranged on the top surface of the base plate 1.

[0021] Specifically, the lifting component consists of a threaded sleeve 12, a threaded rod 13, a limiting ring 14 and a driven wheel 15.

The driving mechanism consists of a servo motor 16, a driving wheel 17 and a transmission belt 18. The servo motor 16 is fixedly connected to the top surface of the limiting frame 8, the driving wheel 17 is fixedly connected to the output end of the servo motor 16, the transmission belt 18 is meshed with the inner wall of the driving wheel 17, and the transmission belt 18 is meshed with the inner wall of the driven wheel 15, which is used to drive the lifting component to rotate, so as to convert the rotational force into a lifting force for tension adjustment.

When the tension needs to be adjusted, the servo motor 16 is started to drive the active wheel 17 and the transmission belt 18 to rotate. The transmission belt 18 is engaged with the driven wheel 15 to drive the threaded rod 13 to rotate along the inner wall of the limit ring 14. The threaded connection between the threaded rod 13 and the threaded sleeve 12 drives the limit slider 9 to rise and fall and slide along the inner wall of the limit frame 8.
