[0052] The positioning column 431 is gradually moved to the position of the special-shaped side grinding mechanism 4, and the positioning column 431 is gradually slid and clamped in the corresponding positioning slot 551. Since the shape structure of the positioning slot 551 is the same as the shape structure of the side edge of the wooden furniture body 3, when the positioning column 431 is positioned and slid in the positioning slot 551, the longitudinal slide frame 43 is controlled to slide on the multiple guide slide shafts 42, so that the side grinding cylinder 45 and the side grinding sleeve 452 are always in contact with the side edge surface of the wooden furniture body 3, and the second motor 461 is controlled to start driving the second gear 462 to drive the second crown gear 46 and the connecting clamping tube 451 to rotate at high speed, thereby controlling the side grinding cylinder 45 and the side grinding sleeve 452 to rotate at high speed, so as to facilitate the synchronous automatic grinding processing of the side of the wooden furniture body 3 that is positioned and moved and transported through the side grinding sleeve 452, and further improve the grinding efficiency of the wooden furniture body 3;

[0053] While grinding, the vacuum cleaner is turned on, and negative pressure is formed in the suction cylinder 253 and the side grinding cylinder 45 through the connection of the suction main pipe 6, the compensation pipe 47 and the three-way pipe 28, so that the waste chips generated by grinding the upper and lower surfaces are sucked into the suction cylinder 253 through the multiple first suction through grooves 201, and the waste chips generated by grinding the side surface are sucked into the side grinding cylinder 45 through the multiple second suction through grooves 401, and the waste chips are collected to prevent the impact on the operator's body and the environment, thereby improving the use effect of the entire grinding device;

[0054] Among them, by manually rotating the adjusting screw 272, the first seat 27 is driven to drive the top position wear guide 22 to move downward, and the distance between the two wear guides 22 is flexibly adjusted, so as to facilitate the grinding process of wooden furniture bodies 3 with different thicknesses, thereby improving the flexibility of the grinding of the wooden furniture bodies 3;

[0055] Since the longitudinal slide frame 43 is convenient for sliding on the multiple guide slide shafts 42, the spacing of the side grinding cylinders 45 can be flexibly changed, which is convenient for adapting to the grinding of the side grinding cylinders 45 that do not require wide widths, and further improves the flexibility of grinding the wooden furniture body 3.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
