[0048] Reference Figures 1 to 13 The embodiments of the present invention are further described.

[0049] The invention discloses a fully automatic blood bag making machine which has high blood bag production efficiency, simple and reasonable structure and low manufacturing cost.

[0050] The specific implementation scheme of the present invention includes: a feeding device 1 for feeding, correcting and adjusting the tension of two film materials, a positioning device 2 for positioning the two film materials, a film drawing device 3 for moving the two film materials to corresponding workstations during the bag making process, a tube upper device 4 for transmitting a round tube, a break valve and a reflux valve between the two film materials, a needle extraction device 5 for stably transmitting the round tube, the break valve and the reflux valve between the two film materials and completing welding, a tube melting device 6 for completing welding of the round tube, the break valve and the reflux valve to the two film materials, a bag melting device 7 for welding the two film materials together and forming a bag body, a bag cutting device 8 for cutting and forming the bag body, and a film pressing assembly 9 for pressing the two film materials. The needle extraction device 5 extends between the two film materials to open the two layers of film materials and cooperates with the tube upper device 4 and the tube melting device 6. The film drawing device 3, the tube melting device 6, the bag melting device 7 and the bag cutting device 8 are all placed on the machine body.

[0051] The working principle of the bag making machine is:

[0052] 1. On the feeding device 1

[0053] like Figure 2 As shown, the unwinding roller 1201, the first traction roller 1421, the second traction roller 1432, the first deviation correction roller 1311, the second deviation correction roller 1321, the first rotating tube and the second rotating roller 1432 are all rotatably connected to the unwinding frame 11; two rolls of film are respectively fixed on the two unwinding rollers 1201, and when the film is pulled and transmitted, the unwinding roller 1201 rotates accordingly and realizes the unwinding of the film; the film extending from the two unwinding rollers 1201 passes through the first traction roller 1421 and the second traction roller 1432 respectively, and the first traction roller 1 421 and the second traction roller 1432 pull the two film materials respectively; then the two film materials are superimposed and pass through a first deflection correction roller 1311, an adjusting roller 1411 and another first deflection correction roller 1311 in sequence, and the deflection correction rollers are provided with deflection correction spaces for limiting the deflection of the film materials, thereby limiting the deviation of the film materials during transmission, and realizing the first deflection correction of the two film materials superimposed together, and the adjusting roller 1411 drives the two film materials to move up and down through a cylinder or other power device, thereby realizing the adjustment of the tension of the film materials;

[0054] After that, the two films continue to separate, one film passes through a first rotating roller 1422, a second deflection correcting roller 1321, and another first rotating roller 1422 in sequence, and the first rotating rollers 1422 and the second deflection correcting rollers 1321 are arranged alternately, and one film passes through a second rotating roller 1432, another second deflection correcting roller 1321, and another second rotating roller 1432 in sequence, and the second rotating rollers 1432 and the second deflection correcting rollers 1321 of another group are arranged in two rows and alternately, so that the tension adjustment and deflection correction are realized when the two films are separated;

[0055] The two films that are extended at last continue to overlap and pass through the last first deviation-correcting roller 1311 , and then extend toward the film-drawing device 3 .

[0056] 2. On the film drawing device 3

[0057] like Figure 3 As shown, the film-drawing frame 311 is placed on the machine body, and the film material is pulled and transmitted by the conveyor belt 3121 and the material-drawing member 3122 on the film-drawing assembly 312; the two superimposed film materials extending from the feeding device 1 extend from bottom to top toward the receiving platform 21 of the positioning device 2, and collide with the inclined surface of the receiving platform 21 to prevent the two film materials from being scratched; then the two film materials continue to extend to the horizontal top surface of the receiving platform 21, and then the two superimposed film materials extend and pass through the positioning notches 221a of the two positioning plates 221, and the two positioning plates 221 position the two film materials to prevent them from shifting; then the two film materials continue to extend toward the film-drawing device 3; there is also a group of positioning assemblies 22 close to the melting tube device 6, which further positions the film material extending into the melting tube device 6, thereby ensuring that the film material enters the melting tube device 6 more neatly, further improving the accuracy of welding between the tube and the film material;

[0058] The two film materials pass through a film drawing mechanism, a melting tube device 6, a melting bag device 7, a bag cutting device 8 and another film drawing mechanism in sequence; when the film materials pass through the film drawing mechanism, the film materials pass through the material pressing space and the material clamping space, and are placed on the conveyor belt 3121; when the two material drawing mechanisms 31 transmit the film materials, the material pressing pieces 313 thereon are loosened and no longer press the film materials; then the material drawing components on the two material drawing mechanisms 31 are synchronously started, and the first cylinder 3122c drives the top plate 3122d to move toward the film materials until the top plate 3122d and the bottom plate 3122b clamp the conveyor belt 3121 and the film materials, and then the first servo motor 3123 drives the frame 3122a to drive the conveyor belt 3121 and the film materials to move, thereby realizing the transmission of the film materials, and cooperating with the conveyor belt 3121, so that the film materials are not easily deformed or damaged due to the pulling transmission; after the material drawing component pulls and transmits the film materials, it is reset and waits for the next transmission of the film materials;

[0059] During the processes of melting bags, melting tubes, and cutting bags, the pressing piece 313 presses the film material, making it difficult for the film material to move, thereby ensuring that the processing of the blood bag is more stable; when the pressing piece 313 presses the film material, the second cylinder 313b starts and drives the second pressing plate 313c to move toward the first pressing plate 313a until the second pressing plate 313c and the first pressing plate 313a press and fix the conveyor belt 3121 and the film material.

[0060] 3. On the upper tube device 4

[0061] The round tube feeding mechanism 41, the breaking valve feeding mechanism 42, and the return valve feeding mechanism 43 all include a vibrating plate for feeding and a feeding part for transferring the tube material to the transfer carrying mechanism 44; when feeding the tube material, the rotating plate 441 rotates through the round tube feeding mechanism 41, the breaking valve feeding mechanism 42, and the return valve feeding mechanism 43, and at the same time, the latch carrier 442 receives and fixes the round tube, the breaking valve, and the return valve from the round tube feeding mechanism 41, the breaking valve feeding mechanism 42, and the return valve feeding machine respectively;

[0062] Then the feeding mechanism 45 transfers the pipe material on the transfer carrying mechanism 44 to the melting tube device 6; that is, the slide 452 slides on the slide rail 451 toward the rotating disk 441 until the manipulator 453 receives and fixes the pipe material on the latch carrier 442, and then the slide 452 slides toward the melting tube device 6, and the manipulator 453 also transfers the pipe material to between the two film materials, thereby completing the loading of the pipe material; the manipulator 453 can rotate between the melting tube device 6 and the transfer carrying mechanism 44, thereby facilitating the loading of the pipe material;

[0063] The upper pipe device 4 is also provided with a detection device for detecting whether the pipe is transferred in place, whether it is offset, or whether there is a shortage of material. Once the above situation occurs, a corresponding alarm is issued so that the staff can deal with it according to the specific situation.

[0064] 4. On the melting tube device 6

[0065] When the manipulator 453 transfers the tube to the melting tube device 6, the needle extraction device 5 is started, that is, the second servo motor 53 drives the needle extraction assembly 52 between the two layers of film materials and moves toward the manipulator 453 until the plurality of needle extraction pieces 522 on the needle extraction assembly 52 plug the tubes on the manipulator 453 one by one, then the needle is withdrawn and the tube is placed on the welding station, and the tube corresponds to the upper mold 61 and the welding groove of the mold one by one; then the upper mold 61 and the lower mold 32 move toward the tube under the action of the power part until the upper mold 61 and the lower mold 32 cooperate to weld the tube and the two layers of film materials together, and perform sealing welding on the head of the bag body; when the upper module and the lower module weld the tube and the film material, the upper positioning block 63 and the lower positioning block 64 position the part of the tube extending out of the upper module and the lower module to ensure stable welding of the tube;

[0066] The structure of the needle extraction device 5 is simpler. Through the cooperation of the needle extraction assembly 52 and the manipulator 453, the assembly of the tube and the membrane can be realized. Moreover, the assembly of the tube is more stable, and the membrane will not move significantly, thereby ensuring that the two layers of membrane are not easy to move.

[0067] The needle extraction rack 51 ensures the stable operation of the needle extraction assembly 52, and the movable base 521 fixes the needle extraction assembly 52 to ensure the stable insertion of several extraction needles into the tube; the needle extraction member 522 includes a head and a needle nozzle inserted into the tube, and the diameter of the head is larger than the diameter of the tube, thereby ensuring that the tube can be smoothly delivered between the two layers of membrane materials when the needle is recovered, and the tube is not easy to scratch the membrane during this process.

[0068] 5. On the bag melting device 7

[0069] After the pipe and the two film materials are welded, the film pulling device 3 is operated to move the welded film material to the bag melting device 7; after the bag melting process begins, the forming mold 731 and the supporting mold 732 move the film material at the same time under the action of the power member until the forming mold 731 and the material mold cooperate to weld the bag body; the forming mold 731 completes the welding process, and the supporting mold 732 lifts the film material and cooperates with the forming mold 731;

[0070] The bag melting rack 72 is moved on the first bearing rail 71, so as to adjust the position of the bag melting mechanism 73, thereby making the position of the bag body forming more matched with the position of the tube, thereby making the forming of the blood bag more perfect.

[0071] 6. On the bag cutting device 8

[0072] After the bag is formed, the film drawing device 3 moves the film material to the placement table of the bag cutting device 8; after the bag cutting process starts, the laser cutting die assembly 831 is driven by the power component to move toward the placement table until the first laser cutting die 831a cuts the bag on the film material, the second laser cutting die 831b opens the edge of the bag, and the third laser cutting die 831c opens the hole of the bag, thereby completing the cutting of the bag;

[0073] The bag cutting frame 82 moves on the second carrying rail 81 so that the bag cutting mechanism 83 is adjusted to a proper position, thereby ensuring that the bag body can be accurately cut.

[0074] 7. About the film pressing component 9

[0075] At least one film pressing assembly 9 is provided on the tube melting device 6, the bag melting device 7 and the bag cutting device 8. The film pressing assembly 9 includes at least two film pressing parts 91. The two film pressing parts 91 on the tube melting device 6, the bag melting device 7 and the bag cutting device 8 are placed on both sides thereof, so that when the film material is welded to the tube, melt-welded to the bag body and cut to the bag body, the cylinder 91a is pushed to drive the film pressing block 91b to press the film material, so that each processing step can make the film material stably fixed, and the film material is not easy to move and deviate, thereby ensuring the accuracy and stability of the blood bag processing.

[0076] 8. In terms of overall structure

[0077] Regarding the deviation correction and tension adjustment of the film material, the film material is pulled out from the unloading mechanism 12, and the deviation correction process is performed on the film material by the deviation correction mechanism 13 on the feeding device 1. The first deviation correction component 131 corrects the deviation of the two layers of film material when they are superimposed and transmitted, and the second deviation correction component 132 corrects the deviation of the two layers of film material when they are separately transmitted, ensuring that the film material is stably sent to the film pulling device 3; the two film pulling mechanisms on the film pulling device 3 pull the film material synchronously, further ensuring the stable transmission of the film material; and then the positioning device 2 further corrects the deviation of the film material to ensure that the film material is stably transmitted to the melting tube device 6, ensuring the stable and accurate welding of the film material and the tube;

[0078] The first adjusting component 142 and the second adjusting component 143 on the tension adjusting mechanism 14 are used to pull and transmit the two film materials respectively, which increases the tortuosity of the film material when feeding, and also increases the feeding stroke of the film material. At the same time, the tension of the film material can be adjusted by the tension adjusting member 141, and the tension of the film material is guaranteed;

[0079] The tension adjustment mechanism 14 cooperates with the deviation correction mechanism 13, and the states of the two layers of film materials during feeding are separation → overlap → separation → overlap, so that the two layers of film materials can ensure effective adjustment of the tension and stable deviation correction of the film materials.

[0080] Regarding the processing of the bag body, the needle extraction device 5 is pre-extended between the two film materials, and the needle extraction assembly 52 cooperates with the manipulator 453 when the tube is loaded, so as to stably transfer the tube to between the two film materials, and then the needle extraction cooperates with the tube melting device 6 to complete the welding of the tube and the film material; the needle extraction device 5, the tube melting device 6, and the tube loading device 4 cooperate with each other, so that the welding of the tube and the film material is more efficient, stable, and has a lower fault tolerance rate;

[0081] The bag melting mechanism 73 and the bag cutting mechanism 83 on the bag melting device 7 and the bag cutting device 8 can move and adjust their processing positions, so that the bag body processing and forming can be more controllable, ensuring a higher yield rate of the bag body; the melting tube and the melting bag process can be completed by high-frequency welding and other methods;

[0082] The film pressing assembly 9 is used to fix the film material during the bag body melting tube, bag melting and bag cutting processes, so that the film material is not easily offset during processing, thereby ensuring stable transmission and processing of the film material.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
