Efficient automatic pressing and pressure maintaining mechanism

An efficient automatic pressing and pressure maintaining mechanism comprises a pressure maintaining unit, an upper transferring unit, a lower transferring unit and a jacking unit, the pressure maintaining unit, the upper transferring unit and the lower transferring unit are arranged above a working table, and the jacking unit is arranged below the working table. The upper transferring unit, the lower transferring unit and the jacking unit are all located below the pressure maintaining unit. According to the designed automatic pressing and pressure maintaining mechanism, the multiple pressing units are adopted to correspond to different pressure maintaining positions for pressing and pressure maintaining, and the operation efficiency is high; the upper transfer unit and the lower transfer unit alternately feed materials, so that the feeding speed is high, and the efficiency is high; the pressure maintaining unit and the jacking unit are both driven by lead screws, so that the conveying precision is guaranteed,
