A connecting box 17 is fixedly installed on one side of the support frame 1, and a filtering box 23 is slidably installed on the top in the connecting box 17. The filtering box 23 is composed of a frame body and a filtering screen, the top and the bottom of the frame body are both open, and the filtering screen is fixedly installed on the bottom of the frame body.

[0026] The elastic assembly is fixedly installed in the connecting box 17 and is fixedly connected with the bottom of the filter box 23. The elastic assembly comprises four telescopic rods 21. Four protrusions are fixedly installed on the inner wall of the connecting box 17 and correspond to the four telescopic rods 21. The telescopic rods 21 are fixedly installed on the protrusions.

[0028] The working principle of the cotton carding mechanism for producing core-spun yarn provided in the embodiment is as follows:

[0029] The cotton fibers are poured into the filter box 23 in the connecting box 17. The second motor 18 is started to drive the rotation of the connecting rod 19, and the connecting rod 19 drives the rotation of the cam 20. The rotation of the cam 20 drives the upward movement of the filter box 23, and at the same time, the spring 22 is stretched. When the cam 20 is separated from the filter box 23, the filter box 23 moves downward under the cooperation of the spring 22 and the telescopic rod 21, so as to drive the filter box 23 to shake up and down in the process of the rotation of the cam 20, in cooperation with the spring 22 and the telescopic rod 21, so as to generate a vibration effect of the filter box 23, improve the filtering effect of the impurity particles in the cotton fibers, and prevent the impurity particles from being wound more tightly when the cotton fibers are directly carded, so as to cause nodules in the yarn product and make it difficult to use. The filtered impurities fall into the collecting box 24. The collecting box 24 is pulled out of the connecting box 17, so as to facilitate the treatment of the impurities in the collecting box 24.

[0030] Then the filtered cotton fibers are poured onto the conveyor belt. The first motor 2 is started to drive the rotation of the conveyor belt through the driving shaft, so as to convey the cotton fibers. At the same time, the transmission belt drives the rotation of the driven shaft 13, the first pulley 14, the second pulley 16, the limiting rod 3 and the cotton carding roller 5, so as to perform the cotton carding treatment on the cotton fibers.

[0031] When the comb roller 5 needs to be replaced, the movable plate 10 is turned upward, the movable plate 10 drives the upward movement of the connecting piece 11, the connecting piece 11 drives the upward movement of the clamping rod 12, so that the clamping rod 12 is separated from the limiting hole on the circular plate 7 and no longer limits the circular plate 7, then the handle 8 is pulled outward to drive the movement of the comb roller 5, the movement of the comb roller 5 drives the limiting block 6 to slide out of the limiting groove 4, so that the comb roller 5 is taken out from the avoiding hole. Then the new comb roller 5 is inserted through the avoiding hole, so that the limiting block 6 slides into the limiting groove 4.

[0032] Embodiment two, please refer to Figures 5-6 The difference between this embodiment and embodiment one is that the driving assembly includes two rotating rods 28, and the two rotating rods 28 are symmetrically arranged on the connecting box 17. The rotating rod 28 is rotationally connected with the connecting box 17. One end of the rotating rod 28 is fixedly sleeved with a fourth pulley 27, the third pulley 25 is fixedly sleeved on the driven shaft 13, the third pulley 25 and the corresponding fourth pulley 27 are sleeved with the second belt 26, and the end of the rotating rod 28 away from the fourth pulley 27 penetrates through the connecting box 17 and is fixedly sleeved with a first bevel gear 29.

[0033] The connecting box 17 is symmetrically fixedly installed with a connecting block on the inner wall, the connecting block is rotationally installed with a second bevel gear 30, and the second bevel gear 30 is meshed with the first bevel gear 29. The top of the second bevel gear 30 is coaxially fixedly installed with a rotating disc 31, the rotating disc 31 is obliquely arranged, and the top of the rotating disc 31 is fixedly installed with a connecting column 32. The connecting column 32 is located away from the center of the rotating disc 31, and the connecting column 32 cooperates with the filtering box 23 and drives the filtering box 23 to vertically move.

[0034] The difference between this embodiment and embodiment one is that:

[0035] The driven shaft 13 rotates to drive the third pulley 25 to rotate, the third pulley 25 drives the fourth pulley 27 to rotate through the second belt 26, the fourth pulley 27 drives the first bevel gear 29 to rotate through the rotating rod 28, the first bevel gear 29 drives the second bevel gear 30 to rotate, the second bevel gear 30 drives the rotating disc 31 to rotate, and the rotating disc 31 drives the connecting column 32 to rotate. The connecting column 32 moves upward to top the filtering box 23 in the process of rotating, the filtering box 23 moves upward to stretch the spring 22, and when the connecting column 32 is separated from the filtering box 23, the filtering box 23 moves downward through the cooperation of the spring 22 and the telescopic rod 21, so that the filtering box 23 is driven to shake up and down in the process of rotating of the connecting column 32 in cooperation with the spring 22 and the telescopic rod 21, so that the filtering box 23 generates a vibration effect, and the filtering effect on the impurity particles in the cotton fibers is improved.

[0036] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
