[0037] Furthermore, in order to facilitate the adjustment of the adjusting screw 1023 , one end of the adjusting screw 1023 is connected to an adjusting hand wheel 1027 .

[0042] During operation, the reduction motor 11 drives the transmission roller 3 to move the measured bamboo plywood forward. When the measured bamboo plywood hits the lifting baffle 7, there is an induction switch on the lifting baffle 7 to control the reduction motor 11 to move forward and stop moving forward; the auxiliary side thruster 6 returns the bamboo plywood to its position for correction, and the fixed baffle 5 acts as a backrest; the bidirectional slide probe group 10 works at the same time, and the bidirectional slide probe group 10 transmits the measured data to the control system. The control system judges the value and divides it into qualified, extra-thick, extra-thin, and diagonal out-of-tolerance. Then the bidirectional slide probe group 10 returns to its original position, and the lifting baffle 7 descends, and the reduction motor 11 starts to continue moving forward. Qualified products will be released to the next process, and unqualified products will be classified and stacked according to the out-of-tolerance type.

[0043] The working state of the probe is as follows: when the bamboo plywood to be measured is on the table of the transmission roller 3, there will be height differences on the surface of the transmission roller 3 due to the manufacturing error of the transmission roller 3. At this time, some parts of the bamboo plywood to be measured will be suspended in the air, and some parts will not be parallel to the plane of the probe. The data output from the side is inaccurate. Therefore, a universal connection is used inside the probe; when the probe contacts the surface of the bamboo plywood, the pressure of the pneumatic cylinder 1024 makes the entire end face of the probe contact with the workpiece; the elastic force of the countersunk gasket 1035 is adjusted to an appropriate elastic force so that it can rotate without any gaps. Since the end face of the probe always rotates around the center, the radius "A" size remains unchanged, such as Figure 6 、 Figure 7 shown.

[0044] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
