Feeding system of test tube bar code paster

The utility model discloses a feeding system of a test tube bar code paster. The feeding system of the test tube bar code paster comprises a frame body, wherein the frame body comprises a bottom plate and a support erected on the bottom plate; a test tube clamping mechanism, a detachment mechanism, a conveying mechanism, a jack-up mechanism and a pushing mechanism are arranged on the frame body, wherein the test tube clamping mechanism is used for clamping test tubes, the detachment mechanism is used for enabling the test tubes to be detached from a test tube foam seat, the conveying mechanism is used for driving the test tube clamping mechanism to an assigned position, the jack-up mechanism is used for jacking up the test tubes on the test tube clamping mechanism, the pushing mechanism is used for pushing out the test tubes jacked up by the jack-up mechanism. Since the feeding system of the test tube bar code paster is provided with the test tube clamping mechanism, all the test tubes on the test tube foam seat can be clamped at a time, the detachment mechanism can enable the test tube foam seat to be detached from the test tubes automatically, and the clamping efficiency is improved greatly; the jack-up mechanism is matched with the pushing mechanism to jack up a row of test tubes at a time, so as to prevent interferes among all rows of test tubes, which impact test tube pushing work.
