[0038] The double-sided grinding device for wood product processing of the present invention has the following working process:

[0039] During work, the carpenter holds the hand-held slide 13 to facilitate moving the main body 11 as a whole. When starting to work, after the main body 11 is stably placed, the flip armrest 38 is held to flip the working turn plate 40, and the upper side of the working chamber 39 is connected to the outside world. At this time, the wooden product that needs to be polished is placed in the working chamber 39, and the left and right end surfaces of the wooden product are respectively placed in the clamping chambers 21 on the left and right sides. At this time, the rotating disk 23 is rotated. At this time, the rotation of the rotating disk 23 drives the rotating shaft 19 to rotate, and then drives the threaded sleeve 18 to rotate, and then drives the clamping plates 20 to move closer to each other, and the wooden products are conveniently clamped through the clamping plates 20 on the upper and lower sides, and can achieve the effect of adapting to wooden products of different thicknesses. Then, the working turn plate 40 is flipped again, and through the polishing The component 53 grinds the end surface of one side of the wooden product. At the same time, when the power motor 47 is started, it can drive the power shaft 46 to rotate, thereby driving the rotating fan 48 to rotate, and then sucking air through the ventilation duct 44 and rotating the rotating fan 48 to input the air into the guide cavity 51, thereby promoting the air flow in the guide cavity 51, and the wood chips generated in the process of grinding the wooden product by the grinding component 53 are blown off by the flowing air, thereby promoting the effect of grinding the wooden product. When one side of the wooden product is polished, the rotating motor 36 rotates to drive the lifting threaded shaft 37 to rotate, thereby driving the lifting plate 15 on the right to move downward, thereby driving the rotating plate 22 on the right to move downward, and then driving the wooden product clamped in the clamping cavity 21 to drive the left side. The rotating plate 22 moves downward, and at the same time, during the downward movement of the lifting plate 15, the driven gear 58 meshes with the rack 17, and drives the driven gear 58 to rotate during the downward movement of the lifting plate 15, thereby driving the transmission gear 57 to rotate, thereby driving the input shaft 61 to rotate, and then the ratchet 12 is driven to rotate through the ratchet 52 and the inner wall tooth groove of the clamping cavity 54, and then the rotating plate 22 is driven to rotate through the ratchet 12. At this time, the rotating plate 22 rotates and realizes the effect of driving the wooden product to turn over 180 degrees. When the rotating plate 22 moves to the lower limit position, the side surface of the wooden product after grinding is abutted against the upper end surface of the vibration plate 30. At this time, the eccentric motor 43 starts to drive the eccentric shaft 25 to rotate, thereby driving the eccentric rotating drum 24 to rotate, and then through the eccentric The central rotating drum 24 and the eccentric shaft 25 are staggered, which drives the eccentric rotating drum 24 to rotate eccentrically, and then the eccentric rotating drum 24 abuts against the surface of the transmission plate 31, and then the eccentric rotation of the eccentric rotating drum 24 drives the transmission plate 31 to deform and reset, so that the transmission plate 31 vibrates and inputs it into the vibration plate 30, and the vibrating vibration plate 30 shakes off the debris on the surface of the polished wooden product on one side through the vibration, so that the processed wooden product surface is neater. At the same time, when the rotating motor 36 is started, it can drive the active wire wheel 32 to rotate, and then pull the active pull rope 35 wound around the outer cylindrical surface of the active wire wheel 32, and connect it with the connecting pull rope 62 through the active pull rope 35, and pull the rotating wire wheel 63 to overcome the torsional elastic force of the reset torsion spring 64 to rotate,At this time, the rotating wire wheel 63 rotates and drives the lowermost guide shaft 50 to rotate, and then drives the lowermost transmission sprocket 68 to rotate, and drives all the transmission sprockets 68 to rotate through the transmission chain 67, and then drives all the guide shafts 50 to rotate, and then drives all the guide plates 49 to flip, and then guide the direction of the air flow in the guide cavity 51, so that when the rotating plate 22 descends and rotates, the wood chips on the polished surface of the wood product are further blown off by changing the direction of the air flow, and the surface cleanliness of the processed wood product is further improved.
