During operation, the detecting mechanism 30 detects the thickness of the sliver 2, the triggering part 331 is slidably arranged between the upper travel switch 35 and the lower travel switch 35, when the sliver 2 is too thin, the triggering part 331 moves downwards to trigger the lower travel switch 35, and when the sliver 2 is too thick, the triggering part 331 moves upwards to trigger the upper travel switch 35, so that the thickness change condition of the sliver 2 can be detected. The cotton cutting mechanism 50 can cut off the unqualified cotton sliver 2 section from the normal cotton sliver 2, the cotton collecting mechanism 40 drives the cotton barrel and the waste barrel to rotate through the rotary table 42, the sliver guiding mechanism 20, the detecting mechanism 30, the cotton collecting mechanism 40 and the cotton cutting mechanism 50 work cooperatively, the qualified cotton sliver 2 can fall into the cotton barrel, the cut-off unqualified cotton sliver 2 falls into the waste barrel, and detection and automatic sliver breaking operation of the cotton sliver 2 are achieved. Compared with manual detection and slitting, the embodiment of the utility model not only can lighten the labor intensity of workers, but also can detect the diameter of the cotton sliver 2 more accurately, can effectively prevent unqualified products from flowing into the next working procedure, and ensures the quality of products.

In the embodiment of the utility model, the frame 10 is used for installing and fixing other parts, and the frame 10 can be a frame body structure formed by materials such as cast iron, steel and the like. The sliver guide 20 has an inlet end communicating with the cotton outlet of the carding machine and an outlet end located above the cotton receiving mechanism 40 for guiding and conveying the sliver 2 produced by the carding machine. The sliver guiding mechanism 20 comprises a plurality of guide wheel groups 21, the guide wheel groups 21 drive the guide wheels to rotate through motors, and the sliver 2 is driven to be conveyed forwards through friction force.

The detection mechanism 30 includes a supporting wheel 31 disposed on the frame 10, and a moving wheel 34 movably disposed above the supporting wheel 31, wherein one end of the moving wheel 34 and the supporting wheel 31 together form a storage space for the sliver 2, and the other end of the moving wheel 34 is connected to a sliding rod 33 and can slide up and down along the sliding cavity.

When the diameter of the sliver 2 is gradually normal, the moving wheel 34 and the sliding rod 33 move upwards, the signal of the down travel switch 35 disappears, and the first driving member (such as an air cylinder, an electric telescopic rod and the like) drives the cutter 51 to cut off the sliver 2, so that the cut sliver 2 falls into the waste can below. The turntable 42 is then rotated to bring the barrel below the discharge end of the sliver guide 20 for receipt of a conforming sliver 2.

Similarly, when the sliver 2 is thicker, the moving wheel 34 and the sliding rod 33 move upwards, the trigger part 331 can trigger the upper travel switch 35, the cutter 51 mechanism and the rotary table 42 to act, cut off and collect the thicker sliver 2 section, and the specific working mode is similar to that when the sliver 2 is thinner, and is not repeated here.
