Preparation: firstly, packaging films are respectively arranged on an upper film roll (1) and a lower film roll (2), then the upper film roll (1), an upper film (3) and a lower film (4) which are packaged on the lower film roll (2) sequentially pass through a first upper concave roller (7), a second upper concave roller (7), a bag-shaped heat sealing machine (8), a third upper concave roller (7), a sealed linear heat sealing machine (9) and between the upper concave roller and the lower concave roller of a clamping device of an upper film running power device (10), and the upper film (3) and the lower film (4) which are packaged are clamped by pressing an adjusting spring on the upper film running power device (10);
Packaging: the lower concave roller of the upper and lower film running power device (10) is driven by a motor to rotate, and acts on the upper film (3) and the lower film (4) between the upper concave roller and the lower concave roller to enable the upper film (3) and the lower film (4) to run forwards; the blood bag (5) is placed between an upper concave roller and a lower film (4) of the front end of a first upper concave roller (7) and between an upper film (3) and a lower film (4) of the lower concave roller;
When the blood bag (5) passes through the concave cavities of the first upper concave roller (7) and the second upper concave roller (7) to the position of the bag-shaped heat sealing machine (8) between the second upper concave roller (7) and the third upper concave roller (7) under the clamping of the upper film (3) and the lower film (4); the bag-shaped heat sealing machine (8) drives the bag-shaped heat sealing strip to move downwards through the descending mechanism, and heat seals the upper film (3) and the lower film (4) outside the clamping blood bag (5) to form a bag-shaped heat sealing line in a sealing mode;
When the blood bag (5) in the heat sealing packaging bag moves to the position of the linear heat sealing machine (9), the linear heat sealing machine (9) drives the linear heat sealing strip to move downwards through the descending mechanism, the upper film (3) and the lower film (4) outside the blood bag (5) are clamped by the blood bag (5) in the heat sealing packaging bag, and the linear sealing heat sealing is carried out on the blood bag (5) to finish the packaging;
when the packaged blood bag (5) passes through the concave cavity of the upper and lower film operation power device (10) to the cutting device (11); the convex cutters and the concave cutters on the cutting device (11) cut off the upper film (3) and the lower film (4) of the packaged blood bag (5); separating the blood bag after heat sealing packaging from the upper membrane (3) and the lower membrane (4); the upper membrane (3) and the lower membrane (4) continue to run under the clamping movement of the upper concave roller and the lower concave roller of the upper membrane running power device (10) and the lower membrane running power device to package the next blood bag (5).
