The invention relates to a fully-surrounded block pressing machine. The fully-surrounded block pressing machine comprises a feeding inlet, a material storage bin, a block pressing bin and a conveying plate. The feeding inlet is formed in the upper end of the material storage bin. A material blocking plate is installed at an output opening of the material storage bin. The block pressing bin is cylindrical. A driving screw rod is installed on the axis of the block pressing bin, driven by a driving motor and sleeved with a pressing block. The pressing block can slide up and down close to the inner wall of the block pressing bin. A discharging outlet is formed in the lower end of the block pressing bin. The size of the conveying plate is matched with that of the discharging outlet. The conveying plate is pulled and controlled by a mechanical arm. A weight measuring instrument is further installed below the conveying plate and coupled to a control motor. According to the fully-surrounded block pressing machine, the structure is simple, and fully-surrounded squeezing shaping can be achieved by applying force from a single direction, so that iron scrap blocks high in density and convenient to convey and store are convenient to manufacture, and the pressing efficiency is effectively improved.
