[0030] The working process of the blood testing machine is as follows: the starting button 1921 is pressed, and the feeding motors 18 of the twelve feeding lines start to work.

When the discharge sensor 110 senses that there is no material placed on the positioning clamp 16 of the recycling discharge end, the discharge action instruction is transmitted, the material taking device 2 receives the instruction and clamps the blood collection tube and places it on the positioning clamp 16 on the first blood collection tube recycling feeding line and the second blood collection tube recycling feeding line. The feeding motors 18 on the two recycling feeding lines drive the feeding driving shaft 12 to rotate through the transmission belt 17, the feeding driving shaft 12 cooperates with the feeding driven shaft 13 to drive the feeding conveyor belt 11 and the positioning clamp 16 to move away from the material taking device 2, and the recycling of the blood collection tube is completed. When the second discharge sensor 111 senses the material in the positioning clamp 16 of the recycling discharge end through the sensing hole 161, the recycling pause signal is transmitted, and the feeding motor 18 on the recycling feeding line receives the instruction and pauses to wait for the material at the recycling discharge end to be taken away by hand.
