Automatic test tube discharging and labeling system

The invention relates to an automatic test tube discharging and labeling system which solves the problem that existing multi-test-tube specimen collection operation is inconvenient. Comprising a doctor work station control host, a nurse work station control host and an outlet pipe labeling machine, during use, the doctor work station control host sends information codes of patients to the nurse work station control host and an outlet pipe labeling machine controller, and the nurse work station control host transmits instructions to the outlet pipe labeling machine controller; a push plate pushes test tubes to move, so that one test tube at a test tube outlet flows into a test tube conveying groove in a test tube conveying channel, a conveying belt drives the test tubes to move, then the test tubes slide into test tube positioning grooves in a feeding rotary table, a first clamp clamps the test tubes, and the feeding rotary table rotates to convey the test tubes to a test tube labeling machine.
