With the improvement of people's living standards, wooden furniture is becoming more and more popular among the people. The processing of wooden furniture often requires making the wood into strip-shaped board structures, and then cutting and installing these strips. In the process of cutting the strips, the cut strips need to be cut to avoid the cut strips affecting subsequent cutting.

[0003] CN202221087344.7 introduces a device for classifying and unloading wooden boards. When in use, the movable adjustment device can be started to move the positions of the bearing member and the unloading conveying device according to the specifications of the wooden boards to be transported, so that the distance between the two bearing members and the spacing between the two unloading conveying devices can be adapted to the specifications of the wooden boards currently being transported. After that, the two receiving members arranged at intervals can stably receive the wooden boards sorted out on the main conveyor line, and gradually descend by a distance of the thickness of the wooden board under the control of the lifting device. However, the unloading device is not convenient for real-time detection of the size of the unloading wooden boards, and is not convenient for real-time adjustment of the height of the unloading receiving device according to the size of the wooden boards. When unloading wooden boards of different thicknesses, the difference in thickness of the wooden boards is easy to affect each other at the receiving position, resulting in unstable or impossible placement of the wooden boards, and it is relatively inconvenient to receive the wooden boards.
