[0034] Working principle: when in use, the particleboard enters the conveying platform 2 (before the straightness test, the external blower 25 pressurizes the gas and conveys it into the cleaning cylinder 27 through the air pipe 26, and then the air outlet 23 acts on the surface of the particleboard to remove the particle dust on the surface of the particleboard), the inclined rod 2202 will contact the surface of the particleboard and be lifted up by force to deflect, when deflecting, the shaft rod 2203 rotates, the pointer 2205 deflects and displays the number on the display table 2204, and the display information can feedback the thickness information of the particleboard; when the surface of the particleboard meets the specifications, the number information of the display table 2204 does not change during the entire conveying process, and the particleboard is continuously conveyed away from the conveying platform 2 and the testing platform 1; when there is a straightness problem on the surface of the particleboard, the deflection state of the inclined rod 2202 changes, the number information changes, the sensor 2208 feeds back the signal to the testing platform 1, and the particleboard will enter the testing platform 1 for a rest; After the particleboard stops on the detection table 1, the position of the detection plate 4 is adjusted to make it reach the detection position (the hydraulic cylinder 17 is started to extend it and drive the slide 12 to descend, and the two rails 14 move down together with the detection plate 4 until the detection plate 4 descends to the upper side of the particleboard, the detection ball 609 contacts and squeezes the surface of the particleboard, the detection rod 602 moves up, and the reset spring 611 undergoes elastic deformation) and zeroing is performed (during zeroing, the detection plate 4 enters the detection position, the adjustment motor 10 is started to drive the winding disk 9 to rotate, and the winding disk 9 winds the tail piece 613 around the inside of the winding disk 9, so that the traction line 612 is straightened and transmits the tension to the deflection disk 601, and the deflection disk gradually returns to the vertical state so that the clamp seat 604 is in a vertical state. At this time, the feedback ball 605 is just not in contact with the feedback screen 5); then enter the detection link, the detection plate 4 moves horizontally above the particleboard, and during the movement, it is subjected to the elastic force of the compressed reset spring 611, and the detection ball 609 always keeps in contact with the surface of the particle board. When the surface flatness meets the specifications, the multiple detection rods 602 are evenly stressed, the top seat 608 always maintains the same height, the traction line 612 is in the initial straight state, the deflection plate 601 does not deflect, the feedback ball 605 does not contact the feedback screen 5, and no lines are displayed on the feedback screen 5; when the surface flatness changes, the stress state of some detection rods 602 changes, the detection rod 602 moves up or down (the detection rod 602 moves up when the particle board surface is convex, and the detection rod 602 moves down when the particle board surface is concave), the relative positions of the multiple top seats 608 change, the traction line 612 is pulled and bent, the clamp seat 604 at the deflection plate 601 is subjected to tension and drives the deflection plate 601 to deflect, the deflection spring 607 undergoes elastic deformation, the feedback rod 603 is lifted to make the feedback ball 605 contact the back of the feedback screen 5, and lines appear on the feedback screen 5.
