The principle of operation of the present invention will now be described as follows: the whole device is arranged above a polishing table by arranging the hanging plate 1, a solid wood table to be polished is arranged and fixed, then, the hydraulic oil cylinder 2 is started, the fixing seat 3 can drive the two side plates 4 to move downwards, so that strip sand cotton 8 at the bottom side can be abutted against the surface of the solid wood table, and an arc-shaped detection rod 9 at the bottom side is contacted with the surface of the solid wood table;
then, the controller 17 controls the forward and reverse rotation motor 12 to work, the forward and reverse rotation motor 12 rotates for 5 seconds under the control of the controller 17, and rotates reversely for 5 seconds immediately after 1 second interval, and then rotates forwardly for 5 seconds again after 1 second interval, and repeats cyclically, so that under the transmission action of each transmission chain roller 5 and the chain belt 6, each strip-shaped sand cotton 8 can be repeatedly moved, and thus the surface of the solid wood table plate can be repeatedly and roughly polished through the strip-shaped sand cotton 8 at the bottom side, in the rough polishing process, the connection block 101 is inclined through the arc-shaped detection rod 9 under the action of the friction force in the initial state, the friction force of the solid wood table plate to the arc-shaped detection rod 9 is reduced along with the increase of polishing smoothness, and the friction force of the solid wood table plate to the arc-shaped detection rod 9 cannot enable the connection block 101 to incline under the action of the torsional spring 104 at the same side, and at this time, the connection block 101 can continuously touch the pressure switch 106 through the rod 105, and thus the normally-closed electromagnetic valve 153 can be opened through the normally-closed electromagnetic valve 153 and the normally-closed electromagnetic valve 153 at the first electromagnetic valve 153;
at the start of sanding, the suction pump 141 is started simultaneously, and the suction pipe 142, the connecting pipe 143 and the two suction hoppers 144, the wood dust and dust generated during polishing can be adsorbed into the waste bin 13 as much as possible, and then can be trapped inside the waste bin 13 by the stainless steel screen 147, and the gas inside the waste bin 13 under normal conditions is discharged through the gas discharge pipe 145, and after the normally open solenoid valve 146 is closed, the first normally closed solenoid valve 153 is opened, the gas is discharged into the inside of the cylinder 151 through the gas discharge hole 152, in the initial stage of polishing, since the arc-shaped detecting rod 9 drives the connecting block 101 to continuously swing reciprocally, at this time, since the contact time between the extruding rod 105 and the pressure switch 106 is short every time, the air entering the inside of the cylinder 151 can be discharged through the plurality of air holes 156, and as the smoothness of polishing increases, under the action of the torsion spring 104, when the connecting block 101 continuously touches the pressure switch 106 through the extrusion rod 105, more air enters the cylinder 151 through the exhaust hole 152, and the air cannot be discharged in time through the air holes 156, so that the air pressure inside the cylinder 151 is increased, under the action of air pressure, the first piston 154 can be pushed to move upwards until the first piston 154 touches the moving contact of the trigger switch 155, at this time, after the controller 17 receives the electric signal of the trigger switch 155, the forward and reverse rotation motor 12 can be controlled to rotate forward for 10 seconds, at the moment, under the action of the chain belt 6, the strip-shaped sand cotton 8 at the next stage can be driven to replace the original strip-shaped sand cotton 8, and then, the fine polishing is continued in a cyclic and repeated manner under the control of the controller 17, until the next time the trigger switch 155 is triggered again, the strip-shaped sand cotton 8 at the next stage can be continuously replaced through the chain belt 6 until the grinding and polishing work of the solid wood table plate is completed;
before polishing starts, the air extractor pump 141 is controlled to work by the controller 17, the normally-open electromagnetic valve 146 on the exhaust pipe 145 is controlled to be electrified and closed, the second normally-closed electromagnetic valve 21 on the air charging pipe 20 is controlled to be opened, the inside of the round cavity 19 can be charged at the moment, after 10 seconds, the normally-open electromagnetic valve 146 is opened by the controller 17, the second normally-closed electromagnetic valve 21 is closed, the third normally-closed electromagnetic valve 25 in the air permeability pipe 24 is supplied with power in the process of replacing the strip-shaped sand cotton 8 by the controller 17, at the moment, the third normally-closed electromagnetic valve 25 is opened, the air in the round cavity 19 is slowly discharged through the air permeability pipe 24, and in the process of replacing the strip-shaped sand cotton 8, the strip-shaped sand cotton 8 moves to the position of the connecting insulating plate 161, if the surface sand abrasion of the strip-shaped sand cotton 8 is smaller, under the cooperation of the insulating convex particles 166 with the surface of the copper T-shaped block 163, the copper T-shaped block 163 can be driven to move upwards by friction force, at the moment, the copper T-shaped block 163 is separated from the conductive column 164, so that a circuit of the third normally-closed electromagnetic valve 25 on the vent pipe 24 can be disconnected, at the moment, the third normally-closed electromagnetic valve 25 is closed, air in the round cavity 19 cannot be continuously discharged, if the surface of the strip-shaped sand cotton 8 is worn smoothly, the copper T-shaped block 163 cannot be separated from the conductive column 164 due to insufficient friction force, at the moment, the third normally-closed electromagnetic valve 25 continuously keeps an open state, air in the round cavity 19 is gradually discharged, and under the action of the jacking spring 23, the second piston 22 can be pushed to move upwards until the buzzer 27 works after touching a moving contact of the starting switch 26, so that personnel can be reminded of timely replacing the corresponding strip-shaped sand cotton 8.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
