[0025] The principle and structure of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Embodiment

[0027] As Figure 1 shown, a combined plasma quick-freezing device includes a tray 1 for holding plasma, a plasma quick-freezing station and a tray 1 storage station. The plasma quick-freezing station is a flat quick-freezing machine 2. The flat quick-freezing machine 2 is a freezing device widely used in fields such as food processing, drug preservation, and biological sample processing. Its main function is to quickly cool items to the required low temperature in a short time through flat freezing technology, so as to maintain the quality and activity of the items.

[0028] The plate quick-freezing machine 2 includes multiple upper and lower layers of freezing plates arranged in parallel. There are refrigerant pipelines inside the freezing plates, which are connected to other refrigeration units, so as to refrigerate the freezing plates. During quick-freezing, the items to be frozen are placed between the freezing plates. The close contact between the freezing plates and the items improves the heat conduction efficiency, enabling the items to quickly cool down to the required low temperature. Through the multi-layer plate design, the items are frozen at multiple levels, increasing the freezing area and improving the freezing efficiency.

[0029] The plasma is contained in the blood bag 3, and the blood bags 3 are arranged and placed in the tray 1. The tray 1 can be placed into the plate quick-freezing machine 2. The freezing plates of the plate quick-freezing machine 2 are in contact with the blood bags 3 in the tray 1 for heat exchange, so that the blood in the blood bags 3 is quickly frozen.

[0030] The storage station of the tray 1 is a multi-layer shelf 4. The multi-layer shelf 4 is provided with a plurality of storage rack layers 41 arranged up and down, and each storage rack layer 41 can place one tray 1.

[0031] Both the plasma quick-freezing station and the tray storage station are arranged in the same cold storage 6. This is beneficial to the preservation and processing of plasma at low temperature and is conducive to improving the quick-freezing efficiency. The cold storage 6 has a tray 1 access station for the tray 1 to enter and exit the cold storage 6, and also includes a conveying device for conveying the tray 1 between each station.

[0032] The conveying device includes a conveying guide rail 5 and a tray transfer device that moves along the conveying guide rail 5. The tray transfer device includes a tray carrying platform 10 and a tray transfer device for transferring the tray 1 between the tray carrying platform and each station. The tray 1 transfer device can move along the conveying guide rail 5 by means of a slider, a driving of an active wheel, or a traction of a conveyor belt, etc.

[0033] The tray 1 access station includes the cold storage entrance and exit. The cold storage entrance and exit includes a cold storage exit 8 for outputting the frozen plasma finished products outside the cold storage 6 and a cold storage entrance 7 for inputting the plasma to be frozen into the cold storage 6. The cold storage exit 8 and the cold storage entrance 7 are respectively located at both ends of the conveying guide rail 5. The tray 1 storage station and the plasma quick-freezing station are located on the side of the conveying guide rail 5, and the tray 1 storage station is located between the cold storage entrance 7 and the plasma quick-freezing station, so that the tray 1 transfer device starts from the cold storage entrance 7.

[0034] The tray 1 transfer device includes a clamping mechanism capable of clamping the tray 1 and a telescopic control mechanism 18 for controlling the clamping mechanism to extend or retract relative to the tray carrying platform 10, so as to realize the transfer of the tray 1 between the tray carrying platform 10 and other stations. The telescopic control mechanism 18 can be, for example, a cylinder, an electric cylinder, or a hydraulic cylinder, etc.

[0035] The clamping mechanism includes a push plate 9 that can push the tray 1 outwards. The telescopic control device 17 controls the extension or retraction of the push plate 9 towards the tray carrier 10. When the push plate 9 extends, it can push the tray 1 on the tray carrier 10 to other workstations. Two clamping jaws 11 that can move relatively closer or farther away are provided at both ends of the push plate 9. The two clamping jaws 11 are respectively located on both sides of the tray 1. When the two clamping jaws 11 approach each other, they can clamp the tray 1. Thus, when the telescopic mechanism retracts, the tray 1 can be pulled back from other workstations to the tray carrier 10. In this embodiment, slide rails 12 for carrying the tray 1 are provided on the tray carrier 10 on both sides of the lifting conveyor belt, facilitating sliding on the tray carrier 10 and reducing the moving resistance. The two clamping jaws 11 can be connected by a telescopic control device 17 such as a cylinder, an electric cylinder or a hydraulic cylinder. Thus, the distance between the two clamping jaws 11 is controlled by the telescopic movement of the telescopic control device 17, realizing the clamping and fixing of the tray 1. In this embodiment, the two clamping jaws 11 are respectively fixed at both ends of the telescopic control device 17, and the telescopic control device 17 is fixedly connected to the push plate 9.

[0036] As Figure 6 , 7 shown, a lifting conveyor belt, i.e., a liftable conveyor belt, is provided on the tray carrier 10 between the two clamping jaws 11. The lifting conveyor belt is controlled by a lifting device to move up and down relative to the tray carrier 10. The conveying direction of the lifting conveyor belt is perpendicular to the telescopic direction of the telescopic mechanism. The lifting conveyor belt includes a bracket 13 and two juxtaposed sub-conveyor belts 14 provided on the bracket 13. The two sub-conveyor belts 14 are controlled to rotate by a power device such as a motor 19. The bracket 13 is controlled to lift by a lifting control device 15 such as a pneumatic cylinder or a hydraulic cylinder. When the lifting conveyor belt rises, it can lift the tray 1 from the tray carrier 10. When the lifting conveyor belt descends, it can lower the tray 1 onto the tray carrier 10, enabling the tray carrier 10 to bear the gravity of the tray 1.

[0037] Outside the cold storage entrance and exit, there is a conveying device for trays outside the warehouse corresponding to the lifting conveyor belt. The conveying device for trays outside the warehouse conveys the tray 1 through the cold storage entrance and exit to the lifting conveyor belt, or the lifting conveyor belt lifts the tray 1 on the tray carrier 10 and conveys it to the conveying device for trays outside the warehouse through the cold storage entrance and exit. The conveying device for trays outside the warehouse in this example is the outside-warehouse conveyor belt 16. After the lifting conveyor belt rises, it is parallel and continuous with the outside-warehouse conveyor belt 16, so that the tray 1 can be transferred between the lifting conveyor belt and the outside-warehouse conveyor belt 16 through the rotation of the conveyor belt, thereby realizing the entry and exit of the tray 1 carrying bagged plasma into and out of the cold storage 6. Specifically, the following working conditions can be included:

[0038] 1. The plasma tray directly enters the quick-freezing machine from outside the warehouse for quick-freezing

[0039] As Figure 2 , 3 shown, first, the outside-warehouse conveyor belt conveys the tray with plasma products to the cold storage entrance. Inside the cold storage, the conveying device moves along the conveying guide rail to the cold storage entrance. Then the lifting conveyor belt rises to be flush with the outside-warehouse conveyor belt. Then the outside-warehouse conveyor belt rotates to convey the tray to the lifting conveyor belt. The sub-conveyor belt of the lifting conveyor belt rotates so that the tray corresponds to the slide rail on the tray carrier up and down. Then the lifting conveyor belt descends so that the tray falls onto the slide rail. Then the conveying device moves along the conveying guide rail to the flat quick-freezing machine so that the height of the slide rail is flush with the freezing plate of the flat quick-freezing machine. Then the telescopic control mechanism makes the pushing plate extend towards the freezing plate, thereby pushing the tray onto the freezing plate for quick-freezing. Then the telescopic control mechanism retracts, pulling the pushing plate and the clamping jaws back to the tray carrier. 2. The quick-frozen plasma tray is sent outside the warehouse

[0040] As Figure 4 shown, after the quick-freezing is completed, the telescopic control mechanism extends, and the pushing plate and the clamping jaws extend towards the flat quick-freezing machine so that the two clamping jaws are located on both sides of the tray. Then the telescopic control device controls the distance between the two clamping jaws to become smaller, clamping and fixing the tray. Then the telescopic control mechanism retracts, pulling the frozen tray back to the slide rail on the tray carrier. Then, the conveying device moves along the conveying guide rail to the cold storage exit. Then the lifting conveyor belt rises to be flush with the outside-warehouse conveyor belt outside the cold storage exit. Then the sub-conveyor belt of the lifting conveyor belt rotates to convey the tray to the outside-warehouse conveyor belt outside the cold storage exit.

[0041] 3. The plasma tray is placed on the multi-layer shelf for caching after being stored in the warehouse

[0042] As Figure 5As shown in the figure, when there is a large amount of plasma to be frozen quickly and the quick-freezing machine cannot handle it in time, the plasma can be placed on the multi-layer shelves for caching first. First, the conveyor belt outside the warehouse conveys the tray with plasma products to the entrance of the cold storage. Inside the cold storage, the conveying device moves along the conveying guide rail to the entrance of the cold storage. Then, the lifting conveyor belt rises to be flush with the conveyor belt outside the warehouse. Then, the conveyor belt outside the warehouse rotates to convey the tray onto the lifting conveyor belt. The sub-conveyor belt of the lifting conveyor belt rotates to make the tray correspond to the slide rail on the tray carrier platform up and down. Then, the lifting conveyor belt descends to make the tray fall onto the slide rail. Then, the conveying device moves along the conveying guide rail to the multi-layer shelves, making the height of the slide rail flush with one storage shelf layer of the multi-layer shelves. Then, the telescopic control mechanism makes the pushing plate extend towards the storage shelf layer, thereby pushing the tray onto the storage shelf layer. Then, the telescopic control mechanism retracts, pulling the pushing plate and the clamping jaws back to the tray carrier platform.

[0043] IV. Transfer of the plasma tray from the shelf to the freezing plate of the quick-freezing machine

[0044] As Figure 3 shown in the figure, when it is necessary to take plasma from the shelf to the quick-freezing machine for freezing operation, the conveying device can be moved along the conveying guide rail to the multi-layer shelves, making the height of the slide rail flush with one storage shelf layer of the multi-layer shelves. Then, the telescopic control mechanism makes the pushing plate and the clamping jaws extend towards the storage shelf layer, so that the two clamping jaws are located on both sides of the tray. Then, the telescopic control device controls the distance between the two clamping jaws to become smaller, clamping and fixing the tray. Then, the telescopic control mechanism retracts, pulling the frozen tray back to the slide rail on the tray carrier platform. Then, the conveying device moves along the conveying guide rail to the plate quick-freezing machine, making the height of the slide rail flush with the freezing plate of the plate quick-freezing machine. Then, the telescopic control mechanism makes the pushing plate extend towards the freezing plate, thereby pushing the tray onto the freezing plate for quick-freezing. Then, the telescopic control mechanism retracts, pulling the pushing plate and the clamping jaws back to the tray carrier platform.

[0045] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0046] Although this text uses some terms more frequently, it does not exclude the possibility of using other terms. The use of these terms is only for more conveniently describing and explaining the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model. For the execution order of actions, steps, etc. in the devices and methods shown in the specification and drawings, as long as there is no specific explicit order limitation and the output of the previous processing is not used in the subsequent processing, they can be implemented in any order. The use of similar sequential terms (such as "first", "then", "secondly", "again", "then", etc.) for convenience of description does not mean that they must be implemented in such an order.

[0047] Those of ordinary skill in the art should understand that all directional references (such as above, below, upward, up, downward, down, top, bottom, left, right, vertical, horizontal, etc.) are descriptively used in the drawings to assist the reader's understanding and do not represent (such as for position, orientation, or use, etc.) a limitation on the scope of the present utility model defined by the appended claims. It is only for the convenience of describing this application and simplifying the description. Without contrary indication, these directional terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. The directional terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0048] For convenience of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0049] In addition, some ambiguous terms (such as substantially, certain, generally, etc.) can refer to slight inaccuracies or slight deviations in conditions, quantities, values, or dimensions, some of which are within the manufacturing tolerances or margins. It should be noted that the use of terms such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stated, these terms have no special meaning and therefore cannot be understood as a limitation on the protection scope of this application.
