The specific implementation process is as follows: wood 31 to be polished is placed in the two storage pipes 30, respectively, and the lowest wood 31 of the storage pipes 30 falls on the slide plate 70 under the action of gravity. Starting a negative pressure pump and a motor to drive the motor to rotate the upper polishing roller 43 and the lower polishing roller 42; the hydraulic cylinder 90 is operated such that the hydraulic cylinder 90 reciprocates the piston 92 along the inner wall of the communication tube 20. When the piston 92 slides to the right, the piston 92 presses the hydraulic oil in the right side of the communicating pipe 20, the hydraulic oil drives the first plunger 22 to move to one side of the polishing unit, the first plunger 22 pushes the wood 31 on the right slide plate 70, the wood 31 can be contacted with the push plate 72 in the process of pushing the wood 31, the push plate 72 has a limiting effect on the wood 31, the wood 31 and the slide plate 70 can advance together, and the wood 31 is prevented from falling into the blanking port 11 in the advancing process. At the same time, the pressure in the left side of the communication pipe 20 is reduced, and the second plunger 21 moves to the side away from the grinding unit, avoiding the second plunger 21 from interfering with the normal movement of the wood 31. When the sliding block 73 on the sliding plate 70 moves to contact with the left end part of the strip-shaped groove 12, the sliding plate 70 cannot move forward, the sliding plate 70 just completely seals the blanking port 11, at the moment, the first plunger 22 still applies force to the wood 31, the first plunger 22 applies force to enable the push plate 72 to swing leftwards against the force of the second spring 71, the push plate 72 does not block the wood 31 from moving forward any more, and the wood 31 on the sliding plate 70 can be ensured to be smoothly separated from the sliding plate 70 and enter a gap between the upper polishing roller 43 and the lower polishing roller 42. After the wood 31 enters the gap between the upper grinding roller 43 and the lower grinding roller 42, the upper grinding roller 43 and the lower grinding roller 42 grind the upper and lower surfaces of the wood 31, respectively. After the wood 31 is separated from the sliding plate 70, the sliding plate 70 and the pushing plate 72 are restored to the original positions under the action of the first spring 74 and the second spring 71, and the blanking port 11 is opened again. After the first plunger 22 pushes the wood 31 out of the polishing unit, the polished wood 31 can fall into the placement box 10 through the blanking port 11 of the left placement box 10 under the action of gravity. When the piston 92 slides to the left, the piston 92 presses the hydraulic oil in the left side of the communication pipe 20, which drives the second plunger 21 to move to the polishing unit side, and the second plunger 21 pushes the wood 31 on the left slide plate 70 to move to the polishing unit side, and the wood 31 finally falls into the placing box 10 through the blanking port 11 of the right placing box 10 after being polished.
In this process, the negative pressure pump pumps the gas in the suction box 40, and dust and debris generated during the polishing process falls down into the suction box 40 and finally falls on the filter screen 41 in the suction box 40. The gas pumped by the negative pressure pump is discharged through the exhaust pipe 51, the gas drives the turbine in the exhaust pipe 51 to rotate, and the turbine rotates to drive the incomplete gear 62 to rotate together. Since the incomplete gear 62 is engaged with the rack 61, when the incomplete gear 62 rotates, the incomplete gear 62 drives the sliding rod 63 to move up and down along the bottom of the dust box 40 through the sliding frame 60, and when the sliding rod 63 slides up, the right side of the overturning plate 80 is driven to overturn upwards and the left side of the overturning plate 80 is driven to overturn inwards of the dust box 44, and dust and debris on the overturning plate 80 can be transferred into the dust box 44. When the sliding rod 63 slides downwards, the overturning plate 80 gradually returns to the original position under the action of gravity, and the protrusion 81 on the right side of the overturning plate 80 collides with the filter screen 41, so that the filter screen 41 vibrates, and dust on the filter screen 41 is easy to shake down to slide downwards along the filter screen 41, thereby avoiding the blockage of the filter screen 41.
