TECHNICAL FIELD
[0001] The utility model relates to a breathing liquid loading tray, especially a special breathing liquid loading tray for an automatic freeze dryer. BACKGROUND
[0002] Vacuum freeze drying, simply freeze drying, is a drying method that freezes an object to a eutectic point temperature and then removes moisture in the object by sublimation drying under a high vacuum condition, and the freeze-dried powder obtained by the method has the advantages of well maintaining the original activity of the object, maintaining the color and luster of the object, facilitating long-term storage and the like, so that the freeze drying technology is widely applied in the fields of food, medicine, biology, agriculture and the like.
[0003] Among them, the freeze dryer is a necessary equipment required in the freeze drying process. At present, the freeze dryers seen on the market all need to manually place the breathing liquid loading tray. However, with the continuous development of automation and artificial intelligence technology, the freeze dryers also develop towards automation. For the automatic freeze dryer, the breathing liquid loading tray used by the traditional manual operation cannot be adapted to the automatic grabbing operation of the mechanical arm of the automatic freeze dryer, so it is necessary to develop a special breathing liquid loading tray for the automatic taking and placing operation of the grabbing part of the mechanical arm of the automatic freeze dryer. CONTENT OF THE UTILITY MODEL
[0004] The technical problem to be solved by the utility model is to provide a special breathing liquid loading tray for an automatic freeze dryer, which has the advantages of simple structure, convenient processing, small deformation, and high cleaning rate, and is suitable for the automatic taking and placing operation of the grabbing part of the mechanical arm of the automatic freeze dryer.
[0005] For the breathing liquid loading tray that is not suitable for the automatic taking and placing of the grabbing part of the mechanical arm of the automatic freeze dryer on the market at present, the utility model designs a special breathing liquid loading tray matched with the grabbing part operation to realize the automatic feeding and discharging of the breathing liquid loading tray.
[0006] The breathing liquid loading tray seen on the market at present comprises a tray with an open bottom formed by a top plate, a side frame and a bottom edge flange integrally formed, a liquid loading film is heat sealed on the bottom edge flange to seal and cover the open bottom of the tray, mounting holes and feeding holes are formed in the top plate, a breathing film is heat sealed on the mounting holes, a threaded pipe with external threads is arranged at the feeding holes, the threaded pipe is located at the top of the top plate, a nut is screwed on the threaded pipe and is sealed by a sealing gasket sleeved on the threaded pipe.
[0007] The special breathing liquid loading tray for the automatic freeze dryer is provided with first and second flying wings on the top surface of the top plate based on the original structure of the breathing liquid loading tray, and the specific structure is that the first and second flying wings are arranged on the top surface of the top plate.
[0008] A plurality of first bearing plates are arranged on the first flying wing, and the bottom end faces of all the first bearing plates jointly form a bearing surface of the first flying wing; a plurality of first baffles are arranged on the top surface of the first flying wing, and each first baffle is spaced apart along the outer edge of the first flying wing;
[0009] A plurality of second bearing plates are arranged on the second flying wing, and the bottom end faces of all the second bearing plates jointly form a bearing surface of the second flying wing; a plurality of second baffles are arranged on the top surface of the second flying wing, and each second baffle is spaced apart along the outer edge of the second flying wing.
[0010] When the automated freeze dryer uses the grabbing part of the mechanical arm to lift the special respiratory liquid loading tray, the bearing surface of the first flying wing and the bearing surface of the second flying wing are placed on the grabbing part of the mechanical arm, for example, the grabbing part of the mechanical arm can be two lifting rods, at this time, the bearing surface of the first flying wing and the bearing surface of the second flying wing are placed on the two lifting rods respectively. At this time, the first flying wing and the second flying wing bear the entire weight of the tray.
[0011] Considering the space occupied by the tray, the structure of the mechanical arm of the automated freeze dryer, the processing simplicity and other comprehensive factors, the tray described in the scheme is preferably designed as a cuboid structure.
[0012] Considering that the right angles will affect the cleaning rate and the residual amount of the material remaining in the tray after discharging, in the scheme, the right angle connection between the two adjacent side plates of the four side plates of the side frame is changed to smooth connection with a circular arc surface, and in addition, the right angle connection between the four side plates of the side frame and the bottom plate is also changed to smooth connection with a circular arc surface, so as to improve the overall cleaning rate of the tray and reduce the residual amount of the material after discharging.
[0013] Since the first flying wing and the second flying wing bear the weight of the entire tray, in order to ensure the heat sealing connection strength of the respiratory membrane and the bottom plate, in the scheme, the first flying wing is arranged at any edge of the bottom plate, and the second flying wing is arranged at the edge of the bottom plate opposite to the first flying wing. When the grabbing part of the mechanical arm lifts the first flying wing and the second flying wing, under the influence of the upward lifting force and the downward action force generated by the weight of the tray, the heat sealing connection part of the bottom plate and the respiratory membrane is subjected to an outward opening force, which will affect the heat sealing connection strength of the respiratory membrane, and therefore, moving the first flying wing and the second flying wing outward to the edge can reduce the influence of the force and ensure the heat sealing connection strength of the respiratory membrane and the bottom plate.
[0014] In addition, in order to improve the overall strength of the respiratory liquid loading tray, the first flying wing, each first bearing plate, each first baffle, the second flying wing, each second bearing plate and each second baffle are integrally formed with the tray.
[0015] In addition, in order to ensure a smooth connection between the threaded tube and the bottom surface of the base plate, and to prevent the accumulation of materials or debris at the connection between the threaded tube and the bottom surface during cleaning, this solution also integrally molds the threaded tube with the tray. In this case, there are no uneven corners at the connection between the two, but a smooth connection.
[0016] Furthermore, in the aforementioned automated freeze dryer-specific breathing liquid tray, the first flying wing is an L-shaped structure integrally formed from a first vertical support plate and a first horizontal support plate, and the first horizontal support plate is perpendicular to the first vertical support plate; the first vertical support plate is located at the edge of the bottom plate, each first bearing plate is distributed on the bottom surface of the first horizontal support plate, and the side of each first bearing plate is fixed to the first vertical support plate;
[0017] The second flying wing is an L-shaped structure integrally formed by a second vertical support plate and a second horizontal support plate, and the second horizontal support plate is perpendicular to the second vertical support plate; the second vertical support plate is located at the edge of the base plate, and each second bearing plate is distributed on the bottom surface of the second horizontal support plate, and the side of each second bearing plate is fixed to the second vertical support plate.
[0018] Furthermore, in the aforementioned automated freeze dryer-specific breathing liquid tray, the first horizontal support plate is an outwardly folded edge relative to the first vertical support plate; the second horizontal support plate is an outwardly folded edge relative to the second vertical support plate.
[0019] Since the first and second wings bear the weight of the entire pallet, they are prone to warping and deformation. To reduce the deformation of the first and second wings, this design provides several first reinforcing ribs between the inner side of the first vertical support plate and the top surface of the top plate; and several second reinforcing ribs between the inner side of the second vertical support plate and the top surface of the top plate, in order to improve the overall strength of the first and second wings.
[0020] In addition, in order to further improve the overall strength of the first and second wings, this solution makes the first and second reinforcing ribs integrally formed with the tray.
[0021] In addition, to further improve the overall strength of the first and second flying wings, the following adjustments are made to the design: The first bearing plates arranged sequentially in a line from front to back on the bottom surface of the first horizontal support plate are positioned such that the foremost first bearing plate is located at the front edge of the first horizontal support plate, and the last bearing plate is located at the rear edge of the first horizontal support plate; Similarly, the second bearing plates arranged sequentially in a line from front to back on the bottom surface of the second horizontal support plate are positioned such that the foremost second bearing plate is located at the front edge of the second horizontal support plate, and the last bearing plate is located at the rear edge of the second horizontal support plate.
[0022] Further, the automatic freeze dryer special breathing liquid loading tray, wherein, on the four side plates of the side frame, a plurality of positioning pieces are arranged, and the positioning pieces are sequentially and spaced arranged along the circumferential direction of the side frame.
[0023] More preferably, the positioning pieces are integrally formed with the tray.
[0024] The positions of the positioning pieces can be adjusted and designed according to the positions required by the laser limiting on the automatic freeze drying tray, and the positioning pieces can be used as positioning members for laser limiting or can play the role of reinforcing ribs.
[0025] Further, the automatic freeze dryer special breathing liquid loading tray, wherein, on the bottom surface of the top plate, at least one connecting reinforcing rib protruding downward is arranged, and each connecting reinforcing rib surrounds the periphery of the mounting hole; when the breathing membrane is heat sealed and covered on the mounting hole, each connecting reinforcing rib is in the heat sealing area of the breathing membrane.

DETAILED DESCRIPTION
[0037] The technical scheme of the utility model will be described further in detail below in combination with the drawings and preferred embodiments.
[0038] In the following, example embodiments will be described more fully with reference to the accompanying drawings, in which example embodiments can be embodied in different forms and should not be construed as being limited to the embodiments set forth herein. Rather, the purpose of the embodiments is to make the present disclosure thorough and complete, and to fully enable a person skilled in the art to understand the scope of the present disclosure.
[0039] For the convenience of description, the utility model defines the left hand side direction as "front", the right hand side direction as "back", and the center line of the transverse direction as the boundary line. Figure 1 Figure 1 Figure 1 The side of the component close to the center line of the transverse direction is defined as "inner", and the side of the component away from the center line of the transverse direction is defined as "outer". The direction words of "front", "back", "inner", and "outer" in the utility model are defined as the direction.
[0040] In the description of the utility model, it is necessary to explain that the terms "front", "back", "inner", "outer" and the like indicate the position or location relationship based on the position or location relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0041] As shown in Figure 1 The special breathing liquid loading tray for the automatic freeze dryer in the embodiment comprises a tray with an open bottom formed by a top plate 1, a side frame 2 and a bottom edge 3, and a liquid loading film 4 is heat sealed on the bottom edge 3 to seal the open bottom of the tray. The liquid loading film 4 can be made of modified PP material, and a transparent liquid loading film 4 is usually used.
[0042] As shown in Figure 1 , Figure 2 and Figure 3 A mounting hole 102 and a feeding hole 101 are formed in the top plate 1, and a breathing film 5 is heat sealed on the mounting hole 102. Here, the breathing film 5 can be directly heat sealed on the bottom surface of the bottom plate 1. In order to improve the heat sealing strength of the breathing film 5, at least one connecting reinforcing rib 17 protruding downward can be arranged on the bottom surface of the top plate 1, as shown in Figure 3 , Figure 4 and Figure 5 Each connecting reinforcing rib 17 surrounds the periphery of the mounting hole 102. When the breathing film 5 is heat sealed on the mounting hole 102, each connecting reinforcing rib 17 is in the heat sealing area of the breathing film 5.
[0043] The cross section of the connecting reinforcing rib 17 in the embodiment is preferably triangular. Each connecting reinforcing rib 17 is integrally formed with the tray.
[0044] The breathing film 5 in the scheme is a combined waterproof and breathable film structure composed of an inner waterproof and breathable sealing film and an outer mesh cloth stacked above the inner waterproof and breathable sealing film. The inner waterproof and breathable sealing film is preferably made of PTFE material.
[0045] As shown in Figure 2As shown, the threaded pipe 6 with external thread is arranged at the feed hole 101, and the threaded pipe 6 is located at the top of the top plate, and the nut 8 is screwed on the threaded pipe 6 and sealed by the sealing gasket 7 sleeved on the threaded pipe 6. At this time, if the threaded pipe 6 is fixed at the feed hole 101 after hot pressing, there will be uneven connecting lines between the threaded pipe 6 and the bottom surface of the bottom plate 1, which can easily cause materials or sundries to accumulate at the connecting lines during cleaning, affecting the material discharge rate and cleaning rate. In view of this problem, the threaded pipe 6 is integrally formed with the bottom plate 1 in this embodiment, and at this time, there is no uneven connecting line at the connecting part of the two, but a smooth connection.
[0046] When the above-mentioned respiratory liquid loading disc is used, the threaded pipe 6 faces upward, and the liquid loading film 4 is at the lowermost position. The liquid medicine is poured into the respiratory liquid loading disc through the pipe opening of the threaded pipe 6, and the liquid medicine is supported by the liquid loading film 4. Then, the liquid medicine in the respiratory liquid loading disc is sealed by the nut 8 and the sealing gasket 7. Finally, the respiratory liquid loading disc is sent into the freeze dryer, and the steam in the freeze drying process can penetrate outward through the inner layer of the waterproof and breathable sealing film and the outer layer of the mesh cloth.
[0047] After the freeze drying is completed, the liquid medicine forms a freeze-dried powder, and the discharge of the freeze-dried powder can be performed by breaking the liquid loading film 4 or by rotating out the nut 8. If the liquid loading film 4 is broken, the respiratory liquid loading disc is a disposable product at this time. If the nut 8 is rotated out, the discharge is performed from the pipe opening of the threaded pipe 6, and at this time, the respiratory liquid loading disc can be repeatedly used after cleaning and other operations. The specific discharge method is determined according to the specific situation, and no requirement is made here.
[0048] As shown in Figure 1 , Figure 2 and Figure 3 , the first flying wing 9 and the second flying wing 13 are arranged on the top surface of the top plate 1. A plurality of first bearing plates 12 are arranged on the first flying wing 9, and the bottom end faces of all the first bearing plates 12 jointly form the bearing surface of the first flying wing 9. A plurality of second bearing plates 16 are arranged on the second flying wing 13, and the bottom end faces of all the second bearing plates 16 jointly form the bearing surface of the second flying wing 13.
[0049] When the respiratory liquid loading discs are arranged in sequence, for example, one after another during transportation, in order to prevent the phenomenon of stacking of two adjacent respiratory liquid loading discs, a plurality of first baffles 10 are arranged on the top surface of the first flying wing 9, and each first baffle 10 is distributed along the outer edge of the first flying wing 9. A plurality of second baffles 14 are arranged on the top surface of the second flying wing 13, and each second baffle 14 is distributed along the outer edge of the second flying wing 13.
[0050] When the automated freeze dryer lifts the special respiratory liquid-carrying tray by the grabbing part of the mechanical arm, the bearing surface of the first flying wing 9 and the bearing surface of the second flying wing 13 rest on the grabbing part of the mechanical part, at this time, the first flying wing 9 and the second flying wing 13 bear the weight of the whole tray.
[0051] Considering the space occupied by the tray, the structure of the mechanical arm of the automated freeze dryer, processing and other factors, in the embodiment, the tray is preferably a cuboid structure, at this time, the side frame 2 is composed of four side plates, considering the material discharge rate and the cleaning rate of the tray, in the embodiment, each two adjacent side plates of the side frame 2 are smoothly connected by a circular arc surface, in addition, the side frame 2 and the bottom plate 1 are also smoothly connected by a circular arc surface.
[0052] Since the first flying wing 9 and the second flying wing 13 bear the weight of the whole tray, in order to ensure the heat sealing connection strength of the respiratory membrane 5 and the bottom plate 1, the first flying wing 9 is arranged at any edge of the bottom plate 1, and the second flying wing 13 is arranged at the edge of the bottom plate 1 opposite to the first flying wing 9.
[0053] When the grabbing part of the mechanical arm lifts the first flying wing 9 and the second flying wing 13, under the influence of the upward lifting force and the downward action force generated by the weight of the tray, the heat sealing connection part of the bottom plate 1 and the respiratory membrane 5 is subjected to an outward opening action force, which will affect the heat sealing connection strength of the respiratory membrane, therefore, moving the first flying wing 9 and the second flying wing 13 outward to the edge can reduce the influence of the action force and ensure the heat sealing connection strength between the respiratory membrane 5 and the bottom plate 1.
[0054] In addition, in order to improve the overall strength of the respiratory liquid-carrying tray, the first flying wing 9, each first bearing plate 12, each first baffle plate 10, the second flying wing 13, each second bearing plate 16 and each second baffle plate 14 are integrally formed with the tray.
[0055] In the embodiment, the first flying wing 9 and the second flying wing 13 are preferably L-shaped structures, and the specific structure is described as follows:
[0056] As shown in Figure 1 , Figure 3 and Figure 4 , the first flying wing 9 is an L-shaped structure integrally formed by a first vertical support plate 902 and a first horizontal support plate 901, and the first horizontal support plate 901 is perpendicular to the first vertical support plate 902. The first vertical support plate 902 is located at the edge of the bottom plate 1, each first bearing plate 12 is distributed on the bottom surface of the first horizontal support plate 901, and the side of each first bearing plate 12 is fixed to the first vertical support plate 902.
[0057] As shown in Figure 1 , Figure 2 and Figure 3As shown, the second flying wing 13 is an L-shaped structure integrally formed by a second vertical support plate 1302 and a second horizontal support plate 1301, and the second horizontal support plate 1301 is perpendicular to the second vertical support plate 1302. The second vertical support plate 1302 is located at the edge of the bottom plate 1, each second bearing plate 16 is distributed on the bottom surface of the second horizontal support plate 1301, and the side of each second bearing plate 16 is fixed to the second vertical support plate 1302.
[0058] In this embodiment, the first flying wing 9 and the second flying wing 13 are preferably outwardly folded structures, and the specific structure is described as follows: the first horizontal support plate 901 is an outwardly folded edge relative to the first vertical support plate 902; the second horizontal support plate 1301 is an outwardly folded edge relative to the second vertical support plate 1302. Such arrangement can also improve the external cleaning degree of the breathing liquid tray and the subsequent sterilization effect.
[0059] The tray and each component integrally formed with the tray are made of plastic material. Plastic material is extremely prone to deformation under the action of cold and heat. Since the first flying wing 9 and the second flying wing 13 are force receiving members bearing the weight of the entire breathing liquid tray, in order to further reduce the deformation amount of the first flying wing 9 and the second flying wing 13, a plurality of first reinforcing ribs 11 are arranged between the inner side of the first vertical support plate 902 and the top surface of the top plate 1, and a plurality of second reinforcing ribs 15 are arranged between the inner side of the second vertical support plate 1302 and the top surface of the top plate 1.
[0060] Among them, the first reinforcing rib 11 can be a triangular support plate structure 11a located in the corner formed by the first vertical support plate 902 and the top plate 1, as shown in Figure 4 As shown, the second reinforcing rib 15 can also be a triangular support plate structure 11a.
[0061] The first reinforcing rib 11 can also be a support plate structure 11b located in the corner formed by the first vertical support plate 902 and the top plate 1, and the top of which directly extends to the top end of the first vertical support plate 902, as shown in Figure 6 and Figure 7 As shown, the second reinforcing rib 15 can also be a support plate structure 11b.
[0062] Considering that the integrally formed strength is higher, it is preferred that the first reinforcing rib 11 and the second reinforcing rib 15 are integrally formed with the tray.
[0063] In order to further reduce the deformation amount of the first flying wing 9 and the second flying wing 13, the distribution of each first bearing plate 12 and each second bearing plate 16 is adjusted as follows in this embodiment:
[0064] The first bearing plates 12 are arranged in a straight line from front to back on the bottom surface of the first horizontal support plate 901. The first bearing plate 12a at the frontmost end is located at the front edge of the first horizontal support plate 901, and the first bearing plate 12b at the rearmost end is located at the rear edge of the first horizontal support plate 901. Figure 3 As shown.
[0065] The second bearing plates 16 are arranged in a straight line from front to back on the bottom surface of the second horizontal support plate 1301. The first bearing plate 16a is located at the front edge of the second horizontal support plate 1301, and the last bearing plate 16b is located at the rear edge of the second horizontal support plate 1301. Figure 4 As shown.
[0066] The first bearing plate 12a at the foremost end, the first bearing plate 12b at the rearmost end, the second bearing plate 16a at the foremost end, and the second bearing plate 16b at the rearmost end play a crucial role in preventing deformation of the first flying wing 9 and the second flying wing 13.
[0067] In this embodiment, as Figure 1 and Figure 2 As shown, several positioning pieces are provided on the four side plates of the side frame 2, and each positioning piece is integrally formed with the tray.
[0068] For ease of description, each positioning piece along the long side of the side frame 2 is defined as a first positioning piece 18a, and each positioning piece along the short side of the side frame 2 is defined as a second positioning piece 18b. The first positioning pieces 18a are arranged sequentially and at intervals along the long side of the side frame 2, and the second positioning pieces 18b are arranged sequentially and at intervals along the short side of the side frame 2.
[0069] The positions of each first positioning piece 18a and each second positioning piece 18b are set according to actual needs and are not restricted here. The positions of the above positioning pieces can be adjusted according to the laser limit position required for the breathing liquid tray on the automatic freeze dryer. They can be used as positioning parts for laser limit and also serve as reinforcing ribs.
[0070] In practical operation, each of the second positioning pieces 18b in the short side direction can be used as a positioning component for laser limiting, and each of the first positioning pieces 18a in the long side direction can be used as a reinforcing rib component. Alternatively, the second positioning pieces 18b in the long side direction can be used as a positioning component for laser limiting, and each of the first positioning pieces 18a in the short side direction can be used as a reinforcing rib component.
[0071] Also, several of the second positioning pieces 18b in the short direction can be selected as the positioning members for laser limiting, and the rest of the second positioning pieces 18b and the first positioning pieces 18a in the long direction are all reinforcing rib members.
[0072] Also, several of the first positioning pieces 18a in the long direction can be selected as the positioning members for laser limiting, and the rest of the first positioning pieces 18a and the second positioning pieces 18b in the short direction are all reinforcing rib members.
[0073] Also, several of the first positioning pieces 18a in the long direction and several of the second positioning pieces 18b in the short direction can be selected as the positioning members for laser limiting, and the rest of the first positioning pieces 18a and the second positioning pieces 18b are all reinforcing rib members.
[0074] The automatic freeze-drying machine special breathing liquid loading tray with the above structure has the advantages of simple structure, convenient processing, small deformation, small material residue, and suitability for automatic freeze-drying machines.
[0075] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application in any other form, and any modification or equivalent change made according to the technical essence of the present application still falls within the scope of the present application.
