Description

Technical Field

[0001] This invention relates to the field of bag-breaking machines, and particularly to a bag-breaking machine for plasma products. Background Technology

[0002] In the field of blood product manufacturing, the low-temperature ethanol method is currently the most widely used plasma protein separation process. The raw material for this process—human plasma—must be immediately frozen and stored at -30°C to -80°C after collection from plasma banks, and this low temperature must be maintained until it enters the production workshop. The frozen plasma is packaged in double-layered composite plastic bags; the inner layer directly contacts the plasma, while the outer layer provides protection. The bag opening is sealed with heat or a screw seal. During production, the first step is to break open this plastic bag, remove the frozen plasma ice inside, and place it in a thawing tank for subsequent separation and purification.

[0003] Frozen plasma bags need to be broken open to remove the ice inside. Existing automated bag-breaking equipment typically uses an intermittent conveying method: the conveyor belt transports the plasma bag to the cutting station, pauses, and restarts to send the next plasma bag to the station after the cutting device has completed the cutting. In actual use, this step-by-step conveying mode results in a limited overall cycle time due to the frequent start and stop of the conveyor belt, making it difficult to achieve continuous production and thus affecting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a bag-breaking machine and recycling process for plasma products, so as to solve the problem that the bag-breaking machine conveying equipment in the prior art needs to adopt an intermittent conveying mode during use, which affects the overall production efficiency.

[0005] The technical problem to be solved by this invention can be achieved through the following technical solution: A blood plasma product bag-breaking machine, comprising: A support frame having a discharge port and a transport mechanism installed inside the support frame for transporting frozen plasma; A single-sided cutting mechanism is installed on the support frame to perform single-sided opening during the continuous delivery of frozen plasma by the transport mechanism. A bag removal mechanism is installed on the support frame and located at one end of the transport mechanism, away from the side of the transport mechanism where the frozen plasma is opened; A pushing mechanism is installed on the support frame and located at the end of one side of the transport mechanism. When the transport mechanism continuously transports the frozen plasma to be opened to the end, the pushing mechanism pushes the frozen plasma into the de-bagging mechanism. When the frozen plasma from Kaifeng is pushed into the unpacking mechanism, the plasma bag is discharged outside the support frame through the unpacking mechanism and the plasma block falls into the feed port.

[0006] Furthermore, the transport mechanism includes two sprockets rotatably mounted on the support frame, with multiple chains installed between the two sprockets. A tray located within the chains is mounted on the support frame, and the tray contacts the bottom horizontal surface of the chains. Multiple partition plates are evenly installed on the multiple chains, with frozen plasma placed between two partition plates. The single-sided cutting mechanism includes two cutting components mounted on the support frame, which are distributed along the transport mechanism line. After a cutting component completes a cut, the cutting component resets to allow the next piece of frozen plasma to pass through it during transport.

[0007] Furthermore, the cutting assembly includes a mounting base, on which a sliding seat is provided that slides toward the partition plate, a cutting blade assembly is mounted on the sliding seat, a cylinder for driving the sliding seat to move is mounted on the mounting base, a holding member for holding frozen plasma is mounted on the mounting base, and a driving member connected to the mounting base is mounted on the support frame, the driving member driving the mounting base to move closer to the corresponding frozen plasma.

[0008] Furthermore, the driving component includes a movable seat horizontally slidably mounted on the support frame. The movable seat is hinged vertically to a hinge cylinder. A hinge rod is slidably inserted into the free end of the hinge cylinder. A preload spring is installed between the hinge rod and the hinge cylinder. Under normal conditions, the preload spring is in a semi-compressed state. The hinge rod is hinged to the mounting base via a shaft to form a parallelogram mechanism. A guide plate is mounted on the support frame. An inclined guide groove is provided on the guide plate. A driving roller that is slidably tangent to the guide groove is mounted on one of the shafts.

[0009] Furthermore, the holding member includes a connecting rod that is elastically slidably inserted into the mounting base, and two holding rods for holding frozen plasma are installed at the free end of the connecting rod along the length direction of its partition plate.

[0010] Furthermore, the sprocket, chain, and pallet are arranged at an angle, and a baffle is constructed at the bottom of the pallet along its length. Gravity causes the frozen plasma located between the two partition plates to contact the baffle, and the side of the frozen plasma in contact with the baffle is used for cutting by the cutting blade assembly.

[0011] Furthermore, the cutting blade assembly includes multiple vertical serrated blades and horizontal serrated blades mounted on a sliding seat. The cutting edge of the vertical serrated blades is lower than that of the horizontal serrated blades. A through groove is provided on the support plate for the vertical serrated blades to pass through. The horizontal serrated blades are used to cut the upper surface of the frozen plasma bag horizontally.

[0012] Furthermore, the pushing mechanism includes a sliding block elastically slidably mounted on the support frame along the conveying direction of the transport mechanism. Two first sliding rods are symmetrically slidably mounted on the sliding block. A first convex plate is constructed at the end of the two first sliding rods near the bag removal mechanism. A first push plate is elastically and unidirectionally rotatably mounted on the first convex plate. A second sliding rod located above the first sliding rod is slidably mounted on the sliding block. A second convex plate is mounted at one end of the second sliding rod. A second push plate is mounted on the second convex plate. The second push plate passes through the space between the first push plates. Under normal conditions, the first push plate and the second push plate are perpendicular to the chain conveying plane and are respectively limited by the first convex plate and the second convex plate to rotate in a direction away from the bag removal mechanism. Two cylinders are mounted on the sliding block. The two cylinders are used to drive the first sliding rod and the second sliding rod to move, respectively.

[0013] Furthermore, the bag removal mechanism includes two belt rollers rotatably mounted on the support frame via pivots, a drive gear is installed between the two pivots and the two drive gears mesh with each other, and a motor for driving one of the pivots is mounted on the support frame.

[0014] Furthermore, the support frame is equipped with multiple cleaning nozzles for cleaning its interior, with the water inlets of the cleaning nozzles located outside the support frame.

[0015] The beneficial effects of this invention are: The present invention enables the opening of frozen plasma and the discharge of the opened frozen plasma from the plasma bag during the continuous movement of the transport mechanism, effectively ensuring continuity. Compared with the intermittent and paused transport method in the prior art, the continuous transport mechanism effectively improves the continuity of frozen plasma separation, realizes continuous production, and ensures overall production efficiency.

Detailed Implementation

[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figures 1 to 11 As shown, an embodiment of the present invention provides a blood plasma product bag-breaking machine, comprising: The support frame 1 has a discharge port, and a transport mechanism 2 is installed inside the support frame 1 for transporting frozen plasma. It should be noted that the support frame 1 is the casing of a bag-breaking machine in the prior art, which has an internal chamber. The transport mechanism 2 is located inside the chamber, and multiple visual observation windows are rotatably mounted on the bag-breaking machine casing for observing the working status of the internal equipment. In this embodiment, the visual observation window is rotatably mounted at the head of the transport mechanism 2. During use, the visual observation window is in the open state, and the frozen plasma is placed on the transport mechanism 2. Preferably, one or more robotic arms can be paired to transport the frozen plasma to the transport mechanism 2 (e.g., ...). Figure 1As shown), frozen plasma is continuously placed onto the transport mechanism 2 to improve the efficiency of continuous production; The single-sided cutting mechanism 3 is installed on the support frame 1. The single-sided cutting mechanism 3 can open one side of the frozen plasma during the continuous conveying of frozen plasma by the transport mechanism 2. That is to say, when this application is used, the transport mechanism 2 can maintain continuous conveying of frozen plasma without interruption. During the movement of frozen plasma, the single-sided cutting mechanism 3 can open one side of the frozen plasma, thereby effectively ensuring the continuity of production. The bag removal mechanism 4 is installed on the support frame 1 and located at the end of one side of the transport mechanism 2. The bag removal mechanism 4 is away from the side of the transport mechanism 2 where the frozen plasma is opened. The pushing mechanism 5 is installed on the support frame 1 and located at the end of one side of the transport mechanism 2. When the transport mechanism 2 continuously transports the frozen plasma to be opened to the end, the pushing mechanism 5 pushes the frozen plasma into the de-bag mechanism 4. That is, the pushing mechanism 5 is facing the side of the frozen plasma that is to be opened. During the movement, the frozen plasma passes through the single-sided cutting mechanism 3, thereby opening one side of the frozen plasma. As the transport mechanism 2 continues to transport, when the opened frozen plasma is facing the pushing mechanism 5, the pushing mechanism 5 is activated to push the opened frozen plasma into the de-bag mechanism 4. The de-bag mechanism 4 squeezes the opened frozen plasma out of the plasma bag. During the continuous movement of the transport mechanism 2, the frozen plasma can be opened and discharged from the plasma bag, which effectively ensures continuity. Compared with the intermittent stopping transport method in the prior art, the continuous transport of the transport mechanism 2 effectively improves the continuity of frozen plasma separation, realizes continuous production, and ensures the overall production efficiency. When the frozen plasma from Kaifeng is pushed into the unpacking mechanism 4, the plasma bag is discharged outside the support frame 1 through the unpacking mechanism 4 and the plasma block falls into the feed port.

[0020] like Figure 2 and Figure 3As shown, in some embodiments, the transport mechanism 2 includes two sprockets 201 rotatably mounted on the support frame 1, with multiple chains 202 installed between the two sprockets 201. A support plate 204 located within the chains 202 is mounted on the support frame 1, and the support plate 204 contacts the bottom horizontal surface of the chains 202, meaning the support plate 204 provides support. Multiple partition plates 203 are evenly installed on the chains 202, with frozen plasma placed between the partition plates 203. The single-sided cutting mechanism 3 includes two cutting components 301 mounted on the support frame 1. When the cutting components 301 cut the frozen plasma, the support plate 204 provides good support, preventing the chains 202 from pressing down too much and resulting in insufficient cutting force. The two cutting components 301 are linearly distributed along the transport direction of the transport mechanism 2. After each cut, the cutting components 301 complete a reset process. The next piece of frozen plasma from the transport mechanism 2 passes through the cutting assembly 301. That is, after the cutting assembly 301 completes one cut, it needs to move and reset. During the reset process, the next uncut piece of frozen plasma will pass directly through the cutting assembly 301. The reset time of the cutting assembly 301 takes the time it takes for an unopened piece of frozen plasma to pass through. However, since there are two cutting assemblies 301, the unopened frozen plasma will be cut by the second cutting assembly 301 after passing through the first cutting assembly 301. Thus, during the continuous movement of multiple chains 202 and the movement of frozen plasma driven by the separator 203, the two cutting assemblies 301 can avoid the problem of frozen plasma being missed from being opened. Of course, there can be more than two cutting assemblies 301 to ensure that the equipment can continue to operate normally if one of the cutting assemblies 301 is damaged and the machine stops.

[0021] like Figure 4 and Figures 7 to 9As shown, in some embodiments, the cutting assembly 301 includes a mounting base 3011, a sliding seat 3012 that slides toward the partition plate 203 on the mounting base 3011, a cutting blade assembly 3013 mounted on the sliding seat 3012, a cylinder for driving the sliding seat 3012 to move on the mounting base 3011, a pressing member 3014 for pressing frozen plasma on the mounting base 3011, and a driving member 3015 connected to the mounting base 3011 mounted on the support frame 1. The driving member 3015 drives the mounting base 3011 to approach the corresponding moving frozen plasma. When the mounting base 3011 approaches the corresponding moving frozen plasma, it approaches the frozen plasma perpendicularly relative to the frozen plasma. That is, the driving member 3015 drives the mounting base 3011 to move towards the corresponding frozen plasma. When the frozen plasma moves, relative to the frozen plasma, along the transport direction of the transport mechanism 2, the frozen plasma and the mounting base 3011 are relatively stationary. However, perpendicular to the transport mechanism 2, the mounting base 3011 gradually approaches the frozen plasma. When the mounting base 3011 approaches the corresponding frozen plasma, the holding member 3014 will first press against the corresponding frozen plasma. Then, the cylinder drives the sliding base 3012 to move, causing the cutting blade assembly 3013 on the sliding base 3012 to cut one side of the frozen plasma, thereby completing the opening of one side of the frozen plasma. Because the mounting base 3011 and the corresponding frozen plasma are in a relative state at this time, the holding member 3014 or the cutting blade assembly 3013 will not fail to complete the cutting due to the continuous transport of frozen plasma by the transport mechanism 2.

[0022] like Figures 7 to 9As shown, in some embodiments, the driving component 3015 includes a movable seat 30151 horizontally slidably mounted on the support frame 1. The driving method of the movable seat 30151 is not specifically limited here; it can be any driving structure capable of driving the movable seat 30151 to move horizontally. For example, a threaded rod coupled with a motor, with the movable seat 30151 threadedly fitted onto the threaded rod. The horizontal movement of the movable seat 30151 is achieved by the motor driving the screw to rotate. In this embodiment, an electric push rod is mounted on the support frame 1, and one end of the electric push rod is connected to the movable seat 30151. The movable shaft of the electric push rod moves the movable seat 30151. The movable seat 30151 is hinged vertically to a hinge cylinder 30152. A hinge rod 30153 is slidably inserted into the free end of the hinge cylinder 30152. A preload spring 30154 is installed between the hinge rod 30153 and the hinge cylinder 30152. Under normal conditions, the preload spring 30154 is in a semi-compressed state. The hinge rod 30153 is hinged to the mounting base 3011 via a shaft to form a parallelogram mechanism. A guide plate 30155 is installed on the support frame 1. A guide groove 30156 is inclinedly opened on 155. A drive roller 30157 that slides tangentially to the guide groove 30156 is installed on one of the shafts. That is, when the frozen plasma moves, the moving seat 30151 also moves. During the horizontal movement of the moving seat 30151, it drives the hinge cylinder 30152 hinged to it to move, thereby driving the hinge rod 30153 that is slidably inserted into the hinge cylinder 30152 to move. Because the drive roller 30157 is installed on the shaft of one of the hinge rods 30153, and the drive roller 30157... 57. The sliding tangent is within the guide groove 30156, so during the movement of the movable seat 30151, the drive roller 30157 will move along the guide groove 30156. Because the hinge rod 30153 and the hinge cylinder 30152 form a parallelogram mechanism, when the drive roller 30157 moves along the guide groove 30156, it will force the mounting seat 3011 to move vertically, thereby achieving a stable downward tilting movement of the mounting seat 3011, so that the mounting seat 3011 and the corresponding frozen plasma are in a parallel and gradually approaching state. Figure 8As shown, the hinge rod 30153 and the hinge cylinder 30152 are driven at an angle downwards. At this time, the hinge rod 30153 can only extend from the hinge cylinder 30152, but there is no retraction stroke. Therefore, it can ensure that the cutting blade assembly 3013 on the mounting base 3011 is more stable when cutting downwards. After the cutting blade assembly 3013 completes the cutting, the cutting blade assembly 3013 and the mounting base 3011 need to be reset. Therefore, when the cutting blade assembly 3013 moves upwards to reset, the chain 202 is still moving during the reset process of the moving base 30151 driving the mounting base 3011. Therefore, the cutting blade assembly 3013 will contact the partition plate 203. At this time, the moving base 30151 is still in the continuous reset state, and the hinge cylinder 30152 is hinged to the moving base 30152. The hinge cylinder 30152 and the hinge rod 30153 are forced to be pulled apart by a certain distance. During this process, the cutting blade assembly 3013 continues to move. When the side of the cutting blade assembly 3013 no longer contacts the partition plate 203, the hinge rod 30153 is reset to the hinge cylinder 30152 by the pre-tension spring 30154, so as to complete the reset of the moving seat 30151 and the cutting blade assembly 3013. It would be too late to cut the next frozen plasma immediately during this process. Therefore, the next cutting can only be carried out after the next frozen plasma has passed through the cutting blade assembly 3013. Therefore, the number of cutting components 301 is at least two. This cutting method effectively ensures that the chain 202 moves continuously and ensures the continuity of production.

[0023] like Figure 4 and Figure 7 As shown, in some embodiments, the holding member 3014 includes a connecting rod 30141 that is elastically slidably inserted into the mounting base 3011. Preferably, a spring is installed between the connecting rod 30141 and the mounting base 3011 to provide elastic holding force to the connecting rod 30141. Two holding rods 30142 for holding frozen plasma are installed at the free end of the connecting rod 30141 along the length direction of its partition plate 203. That is, when the mounting base 3011 gradually approaches the corresponding frozen plasma, the holding rod 30142 contacts the frozen plasma first. After the frozen plasma is elastically held, the cutting blade assembly 3013 will move downward to complete the cutting, so as to prevent the frozen plasma from moving around during the cutting process and affecting the opening effect.

[0024] like Figure 3 and Figure 4As shown, in some embodiments, the sprocket 201, chain 202, and pallet 204 are inclined, meaning that the cutting assembly 301 is also inclined at a certain angle to maintain relative perpendicularity with the frozen plasma. The bottom of the pallet 204 along its length is equipped with a baffle 205. Under the action of gravity, one side of the frozen plasma located between the two partition plates 203 contacts the baffle 205. The side of the frozen plasma that contacts the baffle 205 is used for cutting by the cutting blade assembly 3013. Unlike the conveyor belt on existing bag-breaking machines, in this application, after the sprocket 201 and chain 202 are inclined, after the frozen plasma is transported between the partition plates 203 by the robotic arm, the side of the frozen plasma that needs to be opened will contact the baffle 205 under the action of gravity. This ensures that after the subsequent holding rod 30142 holds the frozen plasma, the cutting blade assembly 3013 can smoothly cut the frozen plasma.

[0025] like Figure 2 and Figure 5 As shown, in some embodiments, the pushing mechanism 5 includes a sliding block 501 elastically slidably mounted on the support frame 1 along the conveying direction of the transport mechanism 2. Two first sliding rods 502 are symmetrically slidably mounted on the sliding block 501. A first protruding plate 503 is constructed at one end of the two first sliding rods 502 near the bag removal mechanism 4. A first push plate 507 is elastically unidirectionally rotatably mounted on the first protruding plate 503. A second sliding rod 504 located above the first sliding rods 502 is slidably mounted on the sliding block 501. A second protruding plate 506 is mounted at one end of the second sliding rod 504. A second push plate 505 is mounted on the second protruding plate 506. The gap formed between the first push plates 507 allows the second push plate 505 to pass through. It should be noted that the first push plate 507 and the second push plate 505 are far apart from each other and are staggered (e.g., Figure 5 As shown), under normal conditions, the first push plate 507 and the second push plate 505 are perpendicular to the conveying plane of the chain 202, and are respectively limited by the first convex plate 503 and the second convex plate 506 to rotate in a direction away from the bag removal mechanism 4. Two cylinders are installed on the sliding block 501, and the two cylinders are used to drive the first sliding rod 502 and the second sliding rod 504 to move. Preferably, because the sprocket 201, the chain 202 and the separator plate 203 have a certain inclination, the pushing mechanism 5 will also be tilted at a corresponding angle to ensure the effect of pushing the opened frozen plasma (e.g. Figure 2As shown in the diagram, when the opened frozen plasma moves to the end of the conveying surface on the chain 202, the frozen plasma is opposite to the two first push plates 507, and the chains 202 are positioned between the first push plates 507 and the second push plates 505. Then, the corresponding cylinder drives the first push plates 507 to push towards the unpacking mechanism 4. At the same time, the second push plates 505 move in the opposite direction. Because the first and second push plates 507 and 505 are unidirectional elastic rotations, the second push plate 505 will rotate after contacting the pushed opened frozen plasma, without affecting the pushing of the opened frozen plasma. The first push plates 507 will remain perpendicular to the conveying surface of the chain 202, thus completing the process of pushing the frozen plasma towards the unpacking mechanism 4. The bagging mechanism 4 moves, while the second pusher plate 505 passes through the two first pushers 507 to move from one side of the multiple chains 202 to the other side, for pushing the next batch of frozen plasma to be opened, thus ensuring continuity and eliminating the need for intermittent movement of the chains 202. Preferably, the first convex plate 503 and the second convex plate 506 are both rotatably mounted on the first pusher plate 507 and the second pusher plate 505 via a pivot rod 7. A torsion spring 8 is sleeved on the pivot rod 7 to provide the first convex plate 503 and the second convex plate 506 with kinetic energy for elastic reset. A limit plate 9 is constructed on both the first convex plate 503 and the second convex plate 506 to limit the rotation angle of the first pusher plate 507 and the second pusher plate 505 (e.g., ...). Figure 5 (As shown).

[0026] like Figure 2 and Figure 7 As shown, in some embodiments, the cutting blade assembly 3013 includes multiple vertical serrated blades 30131 and horizontal serrated blades 30132 mounted on the sliding seat 3012. The cutting edge of the vertical serrated blade 30131 is lower than the cutting edge of the horizontal serrated blade 30132. The support plate 204 has a through groove 30133 for the vertical serrated blade 30131 to pass through. The horizontal serrated blade 30132 is used to horizontally cut the upper surface of the frozen plasma bag. When the cutting blade assembly 3013 moves downward, the vertical serrated blade 30131 cuts one side of the frozen plasma block, and the horizontal serrated blade 30132 directly cuts the side of the frozen plasma bag near the horizontal serrated blade 30132 in the width direction, but does not cut it directly. In this way, when the frozen plasma is squeezed out by the bag removal mechanism 4, it is not only beneficial to squeeze out the frozen plasma, but also to ensure the integrity of the plasma bag and avoid small fragments of the plasma bag.

[0027] like Figure 2 and Figure 6As shown, in some embodiments, the bag removal mechanism 4 includes two belt rollers 401 rotatably mounted on the support frame 1 via pivot rods 402. A drive gear 403 is installed between the two pivot rods 402, and the two drive gears 403 mesh with each other. A motor for driving one of the pivot rods 402 to rotate is installed on the support frame 1. As shown, the motor is connected to one of the pivot rods 402 via a pulley assembly. When one of the belt rollers 401 rotates, the corresponding pivot rod 402 will rotate. The two meshing drive gears 403 enable the two belt rollers 401 to rotate synchronously and in opposite directions. Thus, when the opened frozen plasma is pushed between the two belt rollers 401, the belt rollers 401 will press and transport the unopened side of the frozen plasma bag to the other side of the belt rollers 401, while the plasma inside the plasma bag will fall directly into the discharge port, thereby completing the separation of the opened frozen plasma from the plasma bag.

[0028] like Figure 3 As shown, in some embodiments, the support frame 1 is equipped with a plurality of cleaning nozzles 6 for cleaning its interior. The water inlet of the cleaning nozzle 6 is located outside the support frame 1. Preferably, the support plate 204 is provided with a water filter hole. The cleaning nozzles 6 continuously spray cleaning liquid into the support frame 1 to ensure its interior is clean. Preferably, the support frame 1 is equipped with an air knife assembly 10. One end of the air knife assembly 10 is connected to high-pressure gas to blow away water stains on the frozen plasma and prevent excessive water accumulation on the plasma.

[0029] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
