The support frame 31 is provided with a first motor that drives the driving cylinder 33 to rotate. The ends of the driving cylinder 33 and the ends of the driven cylinder 34 can be respectively provided with gears that mesh with each other, so that the driving cylinder 33 and the driven cylinder 34 can rotate in opposite directions. The gap between the driving cylinder 33 and the driven cylinder 34 matches the thickness of the packaging film 80. The limiting shaft is provided on the support frame 31, and can include a fixed shaft 35 and a movable shaft 36, wherein the fixed shaft 35 is fixedly provided on the support frame 31 at a position higher than the traction cylinder. Two connecting blocks 37 with strip holes can be provided on the support frame 31 at the bottom of the traction cylinder. Both ends of the movable shaft 36 are movably provided in the strip holes. The packaging film 80 on the film cylinder 32 can pass between the driving cylinder 33 and the driven cylinder 34 and bypass the fixed shaft 35 and the movable shaft 36 to be sleeved on the outside of the discharge channel 61.

[0032] The packaging assembly includes two identical heat-sealing assemblies, namely a first heat-sealing member 41 and a second heat-sealing member 42. The first heat-sealing member 41 is arranged on the inclined surface of the inclined platform 20 and is located at the bottom side of the discharge channel 61. The first heat-sealing member 41 is used to seal the two side edges of the packaging film 80; the second heat-sealing member 42 is arranged on the inclined platform 20 at the lower end of the support platform 62 and the discharge channel 61. The second heat-sealing member 42 is used to seal the upper and lower sides of the packaging film 80 and separate the packaged packaging film 80;

A second motor connected to one of the traction wheels is provided in the inclined platform 20. Gears meshing with each other can be provided on the rotating shaft. The second motor can drive the two traction wheels to rotate towards each other. The gap between the two traction wheels matches the thickness of the two layers of packaging film 80, and is used to pull the packaging film 80 to move.

[0034] The working principle of the above technical solution is as follows:

[0035] The blood bag can be initially placed on the discharge table 10, and the packaging film 80 is initially sleeved on the outside of the discharge channel 61, which is beneficial for the two side edges of the packaging film 80 to gradually approach each other in the direction close to the first heat-sealing member 41, so that the first heat-sealing member 41 can press the two side edges of the heat-sealed packaging film 80. In the initial state, the first heat-sealing member 41 can press the two side edges of the heat-sealed packaging film 80, and with the support of the discharge channel 61, the packaging film 80 of the preliminary heat-sealed part forms a cylindrical shape with two ends opened. The pressed part can be guided through two traction wheels and reach the second heat-sealing member 42, and the bottom end of the cylindrical part of the packaging film 80 is pressed by the second heat-sealing member 42. After the initial steps are completed, the blood bag can be packaged; the staff can remove the blood bag from the discharge table 10 The material table 10 is placed in the discharge channel 61, and the blood bag can slide down to the bottom end of the packaging film 80 through the discharge channel 61 and be supported by the support table 62. At this time, the first motor and the second motor are in operation, and the traction cylinder and the traction wheel cooperate to move the packaging film 80 downward. During the movement, the film cylinder 32 rotates to output the packaging film 80, and the limiting shaft prevents the packaging film 80 from being excessively deflected. The movable shaft 36 can move along the strip hole, which is beneficial for the packaging film 80 to pass through and avoids excessive resistance of the limiting shaft causing the packaging film 80 to stretch and deform. After the movement, the first heat sealing member 41 and the second heat sealing member 42 respectively perform the aforementioned heat sealing operation, and the second heat sealing member 42 can heat-seal the top of the previous packaging film 80 while heat-sealing the bottom of the next packaging film 80, and separate the packaged blood bags.

[0036] In another embodiment, if Figure 2 As shown, the heat sealing assembly includes a mounting frame 43, a heat sealing strip and a first cylinder 46. The heat sealing strip includes a movable strip 44 and a fixed strip 45, which are respectively arranged on opposite sides of the mounting frame 43. The first cylinder 46 is arranged on the mounting frame 43. A connecting plate 48 connecting the movable strip 44 is arranged at the end of the cylinder. In order to stably press the movable strip 44 and the fixed strip 45 for packaging, guide pillars 47 are arranged on both sides of the mounting frame 43 perpendicular to the fixed strip 45. Holes matching the guide pillars 47 are arranged on both sides of the connecting plate 48. The connecting plate 48 can be slidably connected to the guide pillars 47 through the holes. A tear cutter is arranged in the middle of the heat sealing strip of the second heat sealing member 42. The tear cutter can be serrated to facilitate cutting of a serrated tear. The heat sealing assembly can drive the movable strip 44 to approach the fixed strip 45 through the first cylinder 46 for pressing and heat sealing.

[0037] In another embodiment, if Figure 3 As shown, a push mechanism 70 is provided on one side of the support platform 62, including a second cylinder 71 and a push plate 72 connected to the second cylinder 71; a conveyor belt 73 is provided on the side of the support platform 62 away from the push mechanism 70. The packaged and separated blood bags can be pushed away by the push mechanism 70 and conveyed to a designated location by the conveyor belt 73 to avoid the accumulation of packaged blood bags affecting subsequent packaging.

[0038] In another embodiment, if Figure 4 As shown, the discharge channel 61 is an elliptical cylinder, and a funnel-shaped connecting cylinder 63 is provided at the higher end thereof to facilitate the entry of the blood bag. The angle of the discharge channel 61 relative to the vertical direction is 45°. The discharge channel 61 of the elliptical cylinder is conducive to the covering of the packaging film 80, and has a small resistance, which is conducive to the traction of the packaging film 80; the angle of the discharge channel 61 can slow down the falling speed of the blood bag, and the blood bag and the packaging film 80 are not easily damaged by collision.

[0039] In another embodiment, an infrared sensor switch may be provided in the upper end of the discharge channel 61. Existing control technology may be used to realize that when the blood bag passes through the upper end of the discharge channel 61, the infrared sensor switch turns on the first motor, the second motor and the heat sealing assembly to perform an action.
