Through the setting of the return spring 13, after the first cylinder 2 completes the operation, the return spring 2 plays a role of elastic rebound on the cylinder seat 4, reducing the loss of the second cylinder 15 itself when it is working.

[0028] In one embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, a guide seat plate 10 is fixedly installed on the other side of the cylinder seat 16, and the rear end of the guide seat plate 10 is movably connected to the guide roller 11; the guide roller 11 is rotatably connected to the connecting shaft, one end of the connecting shaft is provided with a thread, the rotating shaft is threadedly connected to the guide seat plate 10, and the connecting shaft passes through the guide seat plate 10 and is threadedly connected to the hexagonal nut 17, and a flat washer 18 is provided between the guide seat plate 10 and the hexagonal nut 17;

By using the adjusting screw 29 and the plastic corrugated handle 26, the position of the head base 1 can be pre-aligned for adjustment, and the adjusting screw 29 slides through the head base 1 and is threadedly connected with the nut 25, and the other end of the head base 1 is aligned with the nut 25 for limiting;

[0034] Specifically, turning the plastic corrugated handle 26 drives the adjusting screw 29 to rotate, which can drive the flush base 1 to slide back and forth along the outer surface of the third linear axis 22, thereby adjusting the position of the flush base 1 on the third linear axis 22, further ensuring that the excess edge banding strip is located between the cutter head 19 and the bottom knife 6, and the counter 28 can count the number of times the adjusting screw 29 rotates.

[0037] Finally, it is worth mentioning that the operations of the first cylinder 2, the second cylinder 15 and the sensor in the present invention are all controlled by the control system of the automatic edge banding machine.

[0038] The working principle of the utility model is as follows: first, the plastic corrugated handle 26 is twisted to adjust the position of the flush base 1 on the third linear axis 22 to determine that the redundant edge banding strip is located between the cutter head 19 and the bottom cutter 6. Figure 6As shown, during the plate edge banding process, when the plate touches the guide roller 11, the guide roller 11 will drive the bottom knife 6 to move backward, and the plate moves along the tangent of the guide roller 11, so that the excess edge banding strip will enter between the cutter head 19 and the bottom knife 6. When the plate contacts the cutter head 19, the first cylinder 2 and the second cylinder 15 work simultaneously, and the second cylinder 15 pushes the Y-shaped joint 14 to move, thereby causing the cylinder seat 4 to move rightward, so that the cylinder seat 4 can move with the plate, thereby driving the first cylinder 2, the cutter head 19 and the bottom knife 6 to move with the plate. During the movement of the plate and the edge banding strip, the first cylinder 2 drives the cylinder shaft 20 to extend.
