Description

Technical Field

[0001] The invention relates to the technical field of wood product edge grinding, and in particular to a device and method for continuous automatic edge grinding of wood products. Background Art

[0002] Wooden products are products made from wood raw materials after processing. During the processing of wood, it is often necessary to cut the wood. After cutting, a large number of burrs will appear on the surface of the wood. At this time, the burrs on the surface of the board need to be ground.

[0003] Announcement No. CN210121797U discloses a deburring device for wooden products, including a deburring device body, an edge and corner grinding mechanism is arranged on one side outer surface of the deburring device body, a storage box is arranged in the middle of the deburring device body, and a control panel is arranged on the front outer surface of the deburring device body. The deburring device for wooden products described in the utility model is provided with a chip removal mechanism, a feed measurement mechanism and an edge and corner grinding mechanism, which can clean the wood chips on the upper end of the wooden product when discharging, can ensure the cleanliness of the surface of the wooden product, and can limit the height of the wooden product when feeding, and can also measure the height of the wooden product to prevent the wooden product from being too large or too small to damage the deburring device, and can also grind the edges and corners of the wooden product after deburring, which can ensure the quality of the grinding of the wooden product and bring better prospects for use.

[0004] In the above patents and the prior art, when edge grinding wooden products, it is necessary to first fix both sides of the wooden products and then perform edge grinding. However, the fixing parts on both sides cannot be edge ground at one time, so there are defects in the edge grinding. After the edge grinding of the wooden board is completed, due to the presence of the grinding roller, when the wooden board is moved out of the device, the surface of the wooden board will be scratched, thereby affecting the subsequent use of the wooden board. Therefore, we propose a continuous automatic edge grinding device and method for wooden products. Summary of the invention
