Description

Technical Field

[0001] The invention relates to the technical field of wood processing equipment, and more particularly to a wood polishing device. Background Art

[0002] Wood is a general term for plant tissues that develop inward from the vascular cambium, including xylem and parenchyma rays. Wood plays a great supporting role in human life. According to the different properties of wood, people use them in different ways. After the cutting of the wood board is completed, it is necessary to grind the wood board to obtain a certain degree of smoothness or texture to increase the beauty of the furniture. A wood grinding device is needed. A wood grinding device is a device for grinding the edges and burrs on the wood board.

[0003] A Chinese patent discloses a furniture wood surface polishing device with patent number CN202222386848.5. The furniture wood surface polishing device, through the adaptive limiting of the limiting slide and the adjustment adsorption of the suction cup, is convenient for limiting and fixing furniture wood of different thicknesses and heights, and improves the flexible adjustment and fixing of the furniture wood by the polishing device. However, there are still certain problems. The polishing device is provided with polishing components on both sides of the wood, so it can perform double-sided polishing on the wood. However, when the polishing device clamps the wood, the wood is placed in a U-shaped base, and then the suction cup is driven to clamp the wood by screwing the first bolt. Since the U-shaped base has a certain depth and the suction cup that is pressed against the wood also has a certain width, the entire wood cannot be fully presented, so that a part of the surface of the wood cannot be effectively polished, thereby affecting the polishing effect and the quality of the finished product. Therefore, we provide a wood polishing device. Summary of the invention

[0004] The object of the present invention is to provide a wood grinding device to solve the problems raised in the above background technology: When some existing wood grinding devices clamp the wood, the wood is placed in a U-shaped base, and then the suction cup is driven to clamp the wood by screwing a first bolt. Since the U-shaped base has a certain depth and the suction cup that is pressed against the wood also has a certain width, the entire wood cannot be fully presented, so that part of the surface of the wood cannot be effectively polished, thereby affecting the polishing effect and the quality of the finished product.

During the process, the first slide bar is squeezed by the inclined groove on the second groove, which will drive the movable plate to move.
