In this embodiment, the light curtain emitter 5 and the light curtain receiver 6 are each in the form of a strip.
The fixed frame 4 is provided with the light curtain emitter 5 and the light curtain receiver 6, the two side walls of which are respectively fixed with the rotating shafts 2, the corresponding rotating shafts 2 are provided with two groups of mounting brackets 1, the rotating shafts 2 can be rotatably arranged on the corresponding mounting brackets 1 along the axis of the rotating shafts, namely, one group of mounting brackets 1 correspondingly install one rotating shaft 2. By rotating the rotating shaft 2, the axis of the tube product is projected to the surface of the axis of the light curtain emitter and then intersects with the axis acute angle of the light curtain emitter, so that the tube product 7 can be conveniently detected. The light curtain emitter 5 and the light curtain receiver 6 constitute an existing photodetection sensor in this embodiment.

The mounting bracket 1 is also provided with an indicating component, the indicating component comprises a dial 8 and a pointer 9, the dial 8 is fixed with the mounting bracket 1, and the pointer 9 is coaxially arranged with the rotating shaft 2 so as to read the rotating angle of the detection component. Since the fixing frame 4 is provided in this embodiment so that the relative position between the light curtain emitter 5 and the light curtain receiver 6 is fixed, it is only necessary to provide an indication member on the rotating shaft 2 at one side of the detection assembly.
In addition, the detection assembly is electrically connected with a control module, the light curtain emitter 5 and the light curtain receiver 6 are electrically connected with the control module, and the control module calculates the diameter and the speed of the tubular product 7 according to information detected by the light curtain emitter 5 and the light curtain receiver 6.
