[0026] Working principle: when working, generally, the two supporting tables 203 are in a horizontal state, the pushing hydraulic cylinder 204 supports the supporting table 203, the cement board to be processed is horizontally placed on one side supporting table 203, and then the surface of one side of the cement board is processed. Then the cement board is turned over, and the electromagnetic iron 2077 is controlled to be electrified to generate repulsion on the magnetic block 2076, push the support plate 2072 to move outward until the support plate 2072 moves to the side of the support arm 2052 away from the cement board and is in close contact, the position of the support arm 2052 is limited, and the other side of the support arm 2052 contacts the cement board. In the process of moving outward of the support plate 2072, the push plate 2067 is pushed to move along the sliding groove 2065, the rack 2069 is driven to move, the rack 2069 is engaged with the gear 2064, the rotating block 2062 is driven to rotate, the limiting plate 2063 moves towards the cement board, and the end of the limiting plate 2063 is pressed against the surface of the cement board to limit the cement board, so that the cement board does not fall when it is turned to vertical; When the support plate 2072 moves outward, the shaft rod 2091 is pulled to rotate by the guide rod 2093, and then the piston rod 2084 is driven to move along the transverse groove 2082 towards the inside of the top groove 2081. When the support plate 2072 supports the side of the support arm 2052, the support arm 2052 is positioned, so that one side of the push arm 2054 is in close contact with the end face of the suction cup 2083, and then the negative pressure suction force is generated between the suction cup 2083 and the push arm 2054, so that the support force of the support arm 2052 on the cement board when it is turned to vertical is improved, and the support stability is improved.

Since the positions of the containing grooves 2051 on the two support tables 203 are staggered, the turning of the support tables 203 will not be hindered. After being turned to vertical, the cement board is in vertical state and located between the two support tables 203.

At this time, the support plate 2072 is blocked and cannot continue to move outward, so that the limiting plate 2063 cannot be smoothly rotated upward. The electromagnetic iron 2077 on the support table 203 where the cement board is originally placed is controlled to pass through the reverse current, the electromagnetic iron 2077 generates attraction on the magnetic block 2076, the support plate 2072 moves back to the board groove 2071, and then continues to move towards the inside of the board groove 2071, so that the piston rod 2084 is driven to move outward through the shaft rod 2091. During the returning process of the supporting plate 2072, the sliding block 2066 is returned under the elastic force of the first spring 2068, so that the rack 2069 is returned to drive the rotating block 2062 to rotate, so that the limiting plate 2063 no longer limits the cement board; And the outward movement of the piston rod 2084 generates pressure on the pushing arm 2054, which drives the supporting arm 2052 to rotate downward, and the pushing arm 2054 pushes the cement board to move towards the other side supporting table 203 and contact, avoiding the collision impact force generated by the cement board after turning over with the supporting table 203; Then the pushing hydraulic cylinder 204 pulls the supporting table 203 to rotate, at this time the cement board is transferred to another supporting table 203 and completes the turning over, and then the other side surface of the cement board is processed, and during the rotating process, since the supporting plate 2072 moves outward and is no longer blocked, at this time the supporting plate 2072 continues to move outward, so that the limiting plate 2063 rotates to limit the cement board.
