Description

Technical Field

[0001] The utility model relates to the technical field of blood bag processing, in particular to a blood bag body heat sealing device. Background Art

[0002] Heat sealing of blood bags refers to the process of sealing the bag body during the blood bag production process using heat sealing technology. Heat sealing is a method of fusing materials together through heat and is commonly used to connect materials such as plastics and rubber. In blood bag production, heat sealing technology ensures a good seal, preventing blood leakage and ensuring blood quality and safety.

[0003] For example, the polyethylene blood bag heat sealer disclosed in authorization publication number CN217435040U comprises a frame, guide posts disposed at the four corners of the frame, a support top plate positioned on the upper ends of the guide posts, an operating mounting plate mounted on the guide posts with vertical positional freedom, a vertical displacement drive mechanism mounted on the support top plate and connected to the operating mounting plate, an operating table mounted on the upper end of the frame, and a matching blood bag securing plate. The beneficial effect of employing this technical solution is that, by improving the heat sealing method, the heat seal line thickness of the polyethylene pressure-bearing blood bag is made uniform, ensuring that the blood bag's bearing capacity is not reduced.

[0004] Although the above patent makes the heat-sealing line of the polyethylene pressure-bearing blood bag uniform in thickness, ensuring that the bearing pressure of the blood bag does not decrease, during the heat-sealing process, dust in the working environment easily adheres to the bag body, and the above device is not equipped with a dust removal mechanism, so dust removal cannot be achieved before heat-sealing.

A number of negative pressure holes 20 are regularly arranged in the middle of the storage table 3;

[0029] In this embodiment, when heat sealing, the blood bag body is placed on the upper end of the storage table 3, and then the motor 9 is started. The motor 9 drives the screw rod 10 to rotate, and the screw rod 10 drives the frame 1 4 and the frame 2 5 to move simultaneously through the movable sleeve 11, so that the hot pressing plate 6 moves to the top of the storage table 3, and then the hot pressing plate 6 is controlled to descend by the electric push rod 2 12 to heat seal the blood bag.
