Description

Technical Field

[0001] This utility model relates to a blood collection tube sealing machine with automatic transfer function of test tube rack. Background Technology

[0002] A blood collection tube sealing machine is a specialized device used to heat-seal the open end of blood collection tubes. It is widely used in medical testing, biological sample collection, and laboratory automation. Traditional blood collection tube sealing machines typically require the operator to manually push the test tube rack containing the blood collection tubes into the sealing machine and then manually remove the rack after sealing. Existing blood collection tube sealing machines with automatic test tube rack transfer functions still have the following shortcomings: the operation relies on manual labor, resulting in high labor intensity and low efficiency. Furthermore, in large-volume sealing tasks, the test tube rack often shifts due to vibration or uneven force, causing problems such as misaligned sealing positions and uneven sealing, which is detrimental to ensuring the stability and standardization of the testing process. Therefore, improvements and optimizations are proposed to address these issues. Utility Model Content
