[0002] In the medical field, blood bags are key instruments for storing and transporting blood and blood products, and the quality of their seals plays a decisive role in blood safety. During blood collection, storage, and transportation, blood bags must remain sealed and sterile to prevent contamination and leakage, avoid medical accidents caused by blood deterioration, and ensure the safety of medical staff and patients.

[0003] However, the tilt angle adjustment structure of the negative pole of the heat sealing head of the mainstream heat sealing equipment in the current market still has significant technical bottlenecks. In traditional processes, the heat sealing head needs to be calibrated for verticality after assembly, but most equipment uses a fixed negative pole design, which places extremely high demands on the processing accuracy and assembly process of parts. Due to manufacturing errors and assembly deviations, it is often difficult to achieve the expected angle accuracy in actual operations, resulting in uneven temperature distribution and unbalanced pressure conduction during the heat sealing process. This is especially true in the heat sealing process of precision medical devices such as blood bag catheters. It is very easy to cause quality risks such as loose catheter welding and insufficient sealing, which seriously restricts production efficiency and product yield improvement.
