However, in actual operation, due to the high speed of the stepped roller of the carding machine, the amplitude of its jump along the contour of the sliver is not obvious, resulting in the slow response speed of the sensor to the sliver thickness detection and inaccurate detection of the sliver thickness, thus affecting the quality of the produced sliver. Utility Model Content

[0006] Furthermore, the ear seat has a mounting hole, the end of the rotating shaft is connected to a bearing, and the bearing is adapted to be arranged in the mounting hole.
[0007] Furthermore, one end surface of the limiting member contacts the tongue plate, and the other end surface contacts the bearing.
[0008] Furthermore, an end cover is provided on the outer side of the mounting hole.
[0009] Furthermore, the limiting member includes a first limiting member and a second limiting member, the first limiting member is fixedly connected to the upper portion of the rotating shaft to form an integrated structure, the second limiting member is detachably mounted on the rotating shaft, and the tongue plate is located between the first limiting member and the second limiting member.
[0010] Furthermore, the lower portion of the rotating shaft is stepped, including a first connecting section and a second connecting section, the first connecting section is located on the upper side of the second connecting section, and the diameter of the first connecting section is greater than the diameter of the second connecting section.
[0011] Furthermore, the cotton passing hole at the small end of the horn body is rectangular.
[0012] Furthermore, a displacement sensor is included, and the displacement sensor is connected to the other end of the tongue plate.
[0013] The beneficial effect of the utility model is that the utility model fixes the first limit piece and the rotating shaft into an integrated structure, which is easy to install.

[0020] The utility model discloses a detection mechanism for the thickness of cotton strips of a high-speed cotton carding machine. An implementation mode of the utility model is specifically described below in conjunction with the accompanying drawings.
[0021] like Figure 1 As shown, a detection mechanism for the thickness of cotton strips of a high-speed cotton carding machine includes a trumpet body 1 and a tongue plate 2. The trumpet body 1 is in a cone shape and has a cotton hole 3 passing through along the axis. A movable groove 4 is opened on one side of the outer wall of the trumpet body 1, and the movable groove 4 is connected to the cotton hole 3 at a position adjacent to the small end of the trumpet body 1. The cotton hole 3 located at the small end of the trumpet body 1 is rectangular, and the edge connection is smooth.
[0022] Combination Figure 2 and Figure 3As shown, two ear seats 5 are fixed on one side of the outer wall of the speaker body 1 with the movable groove 4 as the symmetry axis. The ear seats 5 have mounting holes, and the mounting holes are on the same axis. A rotating shaft is rotatably connected between the two ear seats 5. A first stopper 7 is provided on the upper part of the rotating shaft, and is fixedly connected to the first stopper 7 to form an integrated structure, which is used to reduce the number of parts used and facilitate disassembly and installation. The lower part of the rotating shaft is stepped, including a first connecting section and a second connecting section. The first connecting section is the upper side of the second connecting section, and the diameter of the first connecting section is larger than the diameter of the second connecting section. The second stopper 8 is suitably arranged at the lower part of the rotating shaft.
[0023] Combination Figure 4 and Figure 5 As shown, the tongue plate 2 is approximately L-shaped, and is sleeved on the rotating shaft through a through hole, and is located between the first limiter 7 and the second limiter 8. The first limiter 7 and the second limiter 8 cooperate to limit the tongue plate 2 so that the tongue plate 2 moves along the movable groove 4. One end of the tongue plate 2 extends into the cotton hole 3, and the other end is connected to a displacement sensor. The upper and lower ends of the rotating shaft are connected to bearings, and the bearings are adapted to be arranged in the mounting hole. One end face of the first limiter 7 and the second limiter 8 contacts the tongue plate 2, and the other end extends into the mounting hole and has a gap with the mounting hole, and the other end face contacts the bearing. An end cover 6 is detachably connected to the outer side of the mounting hole.
[0024] like Figure 6 As shown, when in use, the tampon enters from the cotton hole 3 located at the large end of the trumpet body 1, and exits from the cotton hole 3 located at the small end of the trumpet body 1. When the tampon passes through the cotton hole 3 located at the small end of the trumpet body 1, it will contact one end of the tongue plate 2. The other end of the tongue plate 2 is connected to a spring and a displacement sensor. The tongue plate 2 will rotate around the rotating shaft along the contour of the tampon and reset under the action of the spring. During the rotation of the tongue plate 2, the tongue plate 2 drives the displacement sensor to detect the thickness of the tampon. Both ends of the rotating shaft are connected to bearings, and the bearings are set in the mounting holes. When the tongue plate 2 rotates along the contour of the tampon, the bearings are helpful to reduce the friction suffered by the tongue plate 2, and improve the sensitivity and accuracy of the displacement sensor in detecting the thickness of the tampon.
[0025] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
