[0002] Wood flour refers to the powdered wood. After adding adhesive and mixing, it is pressed and formed into a one-piece cylindrical composite wood by high pressure. The cylindrical composite wood is then placed on a slicer and sliced ​​into thin slices to obtain thin wood boards.

[0003] At present, wood powder is generally processed by crushing wood chips through a grinder. Before entering the grinder, the packaged wood chips are generally poured manually into a wood chip feeding mechanism to prevent material blockage. The wood chip feeding mechanism to prevent material blockage is provided with a discharge port at the bottom, and the wood chips enter the grinder through the discharge port. The existing wood chip feeding mechanism to prevent material blockage is generally a funnel structure, but when feeding, the speed of the grinder is limited, and the material is not discharged very quickly. In the process of feeding a large amount of material, bridging or blocking is prone to occur. At present, the wood is dredged manually with a shovel, which is inefficient and labor-intensive. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content
