[0002] Foamed PVC electromagnetic shielding board is a kind of light, high-strength functional material, and is widely used in the filling and supporting structure inside wind power blades. After the board is formed, the upper and lower surfaces thereof need to be finely polished and the surrounding waste is cut off, so as to meet the assembly requirements. Among them, the polishing process usually needs to process the upper surface of the board first, then turn it over by 180 degrees, and then process the original lower surface in the same way. Therefore, on the automatic production line, a high-efficiency and reliable posture adjusting (turning over) device is needed to complete this work.

[0003] At present, the common board turning over device usually includes a rack, a rotating shaft driven by a motor and a plurality of groups of metal clamps fixed on the rotating shaft.

However, such device has obvious defects in actual application: first, the rigid metal clamps are easy to collide or rub with the surface of the relatively soft foamed PVC board during clamping and turning over, which causes damage such as pits and scratches on the surface of the board, resulting in product scrap; second, the driving system usually drives the rotating shaft directly or through a rigid coupling, and when starting, stopping or load changing, the impact load is directly applied to the motor, which easily causes motor overload and damage in long-term operation, resulting in low equipment reliability and high maintenance cost.
