The invention discloses a sealing machine for biological pharmacy. The sealing machine structurally comprises a sealing machine body, a driving mechanism, a transmission mechanism, a supporting frameand a tin foil turning wheel. The driving mechanism is arranged in the sealing machine body. The sealing machine body is matched with the driving mechanism. The supporting frame is arranged below thesealing machine body. The sealing machine body and the supporting frame are in interference fit. The transmission mechanism is arranged on the supporting frame. In order to achieve the purposes that the sealing machine for biological pharmacy can be easy to operate, low in manufacturing cost, high in sealing efficiency and suitable for large-batch production, the transmission mechanism is arrangedon the sealing machine, the transmission mechanism is driven by a motor on the driving mechanism, the driving mechanism drives a push rod to work downwards through a lifting rod, and therefore a sealing plate can be heated for conducting sealing work on a sealed bottle, and the work efficiency is improved; and a motor spindle controls a guide rod and a guide pillar to be engaged with a rotating wheel through a transmission belt, a conveying belt is driven to work, and containing grooves are formed in the transfer belt so that batched work can be conducted.
