[0002] Solid wood boards are made of natural logs taken from the forest as the door core. They are dried and then scientifically processed through processes such as cutting, planing, mortising, drilling, and high-speed milling. Usually when processing the surface of a wooden board, some special processing is sometimes required, such as grinding the surface of the wooden board to make its surface have a certain curvature and be more beautiful.

According to different curved surface requirements, it is necessary to disassemble and install the grinding mold with the corresponding curvature, which is troublesome to operate and not convenient and fast enough. After each grinding is completed, it is difficult to replace the sandpaper due to the extremely close fit between the sandpaper and the mold, and it is difficult to tear the sandpaper off the mold.

[0010] Preferably, the method for using the grinding device for grinding the curved surface of a wooden board comprises the following steps:

[0011] S1: When the device is used, firstly, sandpaper is manually attached to the bottom of several adjustment blocks, then the wood board to be polished is placed on the lathe, and according to the required curvature of the wood board surface, the first curvature control component and the second curvature control component are controlled to work, thereby controlling the six adjustment blocks to switch from a flat state to bend downward at both ends with the middle of the six adjustment blocks as the axis, so that the shape of the six adjustment blocks is consistent with the curvature of the wood board to be polished, and the sandpaper is deformed synchronously;

[0012] S2: Then, the four-way moving assembly and the adjusting assembly are used to control the six adjusting blocks to move to one end of the area to be polished on the wooden board and contact the top surface thereof, and then the vibration assembly is controlled to drive the sandpaper to generate high-frequency lateral reciprocating vibration, and then the adjusting blocks and the sandpaper are manually controlled to perform arc polishing on the area to be polished on the surface of the wooden board in cooperation with the four-way moving assembly and the adjusting assembly;

[0013] S3: After the sanding of the wooden board is completed, the sanded wooden board is removed. When the sandpaper needs to be replaced or removed, the six adjustment blocks and the sandpaper are first controlled to return to a straight state, and the adjustment block is moved to one end of the top of the sandpaper tearing device with the cooperation of the four-way moving component and the adjustment component, so that one end of the sandpaper contacts the top surface of the sandpaper tearing device, and with the cooperation of the sandpaper tearing device, the sandpaper stuck to the bottom of the adjustment block is automatically removed.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present device, an arc-shaped grinding device for grinding the curvature of a wooden board is arranged at the bottom of an adjusting component, and the arc-shaped grinding device is controlled to move longitudinally by pulling the adjusting component to slide at the bottom of the second sliding frame, and the arc-shaped grinding device is controlled to move laterally by pulling the second sliding frame to slide at the bottom of the first sliding frame, and the adjusting rod is pulled to slide downward along the sliding tube, so that the first spring is extended, thereby adjusting the height of the arc-shaped grinding device, and the angle adjustment of the arc-shaped grinding device is realized through a connecting piece connected by a ball head, and with the cooperation of the first sliding frame, the second sliding frame and the adjusting component, the position, height and angle of the arc-shaped grinding device are adjusted, thereby facilitating the effect of grinding the curvature of the surface of the wooden board.

[0016] In the present invention, when the surface of the wooden board needs to be polished, the dual-axis motor is controlled to drive the rotating disks on both sides to rotate. The force of the rotating disks drives the vibration frame to perform reciprocating lateral motion, and the moving rod synchronously slides back and forth on the fixed frame. The second spring contracts and expands accordingly, thereby realizing high-frequency and small-amplitude vibration of the adjustment block and sandpaper installed at the bottom of the vibration frame, thereby achieving a polishing effect on the surface of the wooden board.

[0017] In the present invention, according to the curvature of the wooden board surface required, the output end of the electric push rod is controlled to contract and drive the slide plate connected thereto to slide in the direction close to the electric push rod. Under the action of the driving gear and the toothed plate, the two slide plates are driven to slide synchronously in the direction close to the opposite side. Under the action of the slide groove on the slide plate, the two hinged plates located on the outermost side are driven to deflect downward synchronously, thereby linking the remaining hinged plates to deflect synchronously, and with the two hinged plates in the middle as the center, the hinged plates on both sides move symmetrically, and at this time, under the action of the limit plate, the six adjustment plates are adjusted from a straight state to an arc state. The longer the moving distance of the slide plate is, the larger the arc formed by the six adjustment blocks is, until the movement of the slide plate is adjusted to the required grinding arc, and then, in order not to interfere with the grinding work of the adjustment block, the second mounting rod is rotated 90 degrees so that the limit plate is away from the adjustment block and the height is higher than the height of the adjustment block, so that the adjustment block can grind the wooden board surface, thereby achieving the effect of grinding the arc surface of the wooden board without replacing the grinding mold of the corresponding curvature for different wooden board grinding needs.

[0018] In the present invention, when the curvature of the wooden board surface is polished and the sandpaper needs to be replaced or removed, the six adjusting blocks are first restored from the curved state to the straight state through the first curvature control component and the second curvature control component, and then the adjusting block is controlled to move to one side of the sticky drum through the four-way moving component and the adjusting component, and the bottom of the sandpaper is flush with the top of the sticky drum, and then one end of the sandpaper is controlled to contact the bottom of the sticky drum, and with the lateral movement of the sandpaper and the stickiness of the outer side of the sticky drum, one end of the sandpaper is stuck to the sticky drum, and with the movement of the sandpaper and the adjusting block, the sandpaper gradually separates from the sticky drum, and then the electric cylinder is controlled to drive the pressing plate to move toward the sticky drum, so that one end of the sandpaper is pressed by the sticky drum and the pressing plate, and finally the adjusting block is continued to slide, so that the adjusting block is completely separated from the sandpaper, and the sandpaper can be removed from the sticky drum, thereby achieving the effect of automatically separating the sandpaper from the adjusting block after the polishing operation is completed.
