The invention relates to the technical field of medicine preparation, and discloses a tablet pressing machine utilizing an electromagnetic bidirectional valve to assist in avoiding collision and in easy access. The tablet pressing machine comprises a pressing machine base, a stamping block shell and a feeding hopper, wherein the top of the pressing machine base is rotatably connected with a driving shaft and a driven shaft; the top and the bottom of a valve body are both fixedly connected with wire wrapping iron blocks; a valve core is movably connected in the valve body; the iron blocks are fixedly connected to the bottom and the top of the valve core; and an oil inlet hole and an oil outlet hole are formed in the right side of the valve body. According to the tablet pressing machine, thewire wrapping iron blocks at the bottom of the valve body are charged and magnetic, so that the valve core is lowered; and hydraulic oil at the top of a stamping block flows to the oil outlet hole through a hydraulic oil pipeline, meanwhile, and the hydraulic oil enters a hydraulic oil groove through the oil inlet hole, so that the stamping block is always in a lifting process after the machine is started, the effect of avoiding the collision is achieved, and cost is saved.
