The invention discloses a test card packaging device. The test card packaging device comprises a processing bottom plate extending in the front-and-back direction; a transition station, a bagging station and a heat sealing station are sequentially arranged on the top surface of the processing bottom plate from the front end to the back end; the back end of the processing bottom plate is connectedwith a discharging plate; a bag supply platform is arranged at the front end of the processing bottom plate; a through channel is formed in the middle of the processing bottom plate in the front-and-back direction; a transfer mechanism is arranged below the through channel; a bag moving mechanism is arranged beside the bag supply platform; a bag opening mechanism is arranged beside the bagging station; a heat sealing mechanism is arranged beside the heat sealing station; a pushing-in mechanism is arranged on the left side of the bagging station; a first feeding mechanism is arranged on the back side of the pushing-in mechanism; and a second feeding mechanism is arranged on the front side of the pushing-in mechanism. By the aid of the test card packaging device, automatic test card packaging is realized, the test card packaging efficiency is substantially improved, and the stability during test card packaging is further improved.
