Accordingly, the present invention provides a structure in which the connection arm 4 can rotate when the tampon is changed, specifically: at the connection position of the connecting arm 4 and the output platen 1, the connecting arm 4 is further provided with a long pressure pin 7 and a short pressure pin 8 extending out of the surface of the output platen 1 along the sliver running direction, one ends of the long pressure pin 7 and the short pressure pin 8 are respectively connected with a long spring 5 and a short spring 6 arranged inside the connecting arm 4, and when the sliver passing through the sliver opening changes, the connecting arm 4 can rotate, and then the output platen 1 is driven to incline, so that the working state of the combing machine is controlled.
In order to ensure that the output platen 1 is in a weight balance state when in a horizontal position, the output platen 1 in the embodiment is made of a steel plate with the thickness of 1.5mm and the material of 0Cr18Ni9Ti, the length of 372mm and the width of 150mm of the output platen 1 are respectively formed by designing one end of the output platen 1, which is more important for the output platen 1, to be provided with a flanging, the distance between the flanging and the center line of the single-eye photoelectric detection device 2 and the fixed shaft 3 is 35mm from the flanging of the output platen 1.
Meanwhile, in order to ensure that the connecting arm 4 can sense the pressure change on the output platen 1 more quickly, the material of the long spring 5 adopted in the embodiment is carbon spring steel wire, the diameter of the steel wire of the long spring 5 is phi 0.7mm, the middle diameter of the long spring 5 is phi 7.2mm, the total length of the long spring 5 is 28mm, and the elastic force range of the long spring 5 is 7.78N-8.65N; the material of the short spring 6 is carbon spring steel wire, the diameter of the steel wire of the short spring 6 is phi 0.8mm, the middle diameter of the short spring 6 is phi 7.2mm, the total length of the short spring 6 is 20mm, and the elastic force range of the short spring 6 is 14.91N-25.36N. Based on the structural design, the invention can rapidly sense the pressure change of the cotton sliver on the output platen and timely make corresponding tilting action, thereby ensuring the detection precision when the combing machine operates at high speed.

The device for detecting sliver breakage by monocular photoelectricity can detect the angle of inclination of the output platen caused by pressure change of the output platen when sliver passes through the sliver opening by the monocular photoelectricity detecting device, and further control the working state of the comber by the master controller connected with the monocular photoelectricity detecting device, namely when sliver breakage occurs or sliver is too thick, the output platen is inclined, at the moment, the monocular photoelectricity detecting device sends a stop signal, and the master controller controls the comber to stop in time.
The concrete steps are as follows: when the cotton sliver is opened normally, the cotton sliver is leveled, the output platen 1 is positioned at the horizontal position, the long spring 5 and the short spring 6 are in a compressed state, when the cotton sliver is broken accidentally, the long spring 5 rebounds to enable the output platen 1 to be lifted, and when the size exceeds a certain size, the monocular photoelectric detection device 2 sends a stop signal, and the combing machine stops; when the cotton sliver is too thick and the output platen 1 is pulled downwards, the output platen 1 resists the pressure of the short spring 6 downwards, and when the size exceeds a certain size, the monocular photoelectric detection device 2 sends a stop signal again, and the combing machine stops.
