[0062] The following will clearly describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, other embodiments obtained by ordinary technicians in this field without making any creative work are all within the scope of protection of this application.

[0063] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0064] In addition, in this application, directional terms such as "upper", "lower", "inner" and "outer" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0065] In industrial production, liquids often need to be repacked—that is, liquids from large tanks are divided into smaller tanks for easier use. Common repackaging methods require the use of pneumatic equipment to achieve vacuum or negative pressure repackaging. However, pneumatic equipment requires an air source, is noisy, and has poor stability and accuracy, resulting in uneven repackaging.

[0066] In order to solve the above problems, an embodiment of the present application provides a packaging device, which does not require pneumatic equipment, has high packaging accuracy, low noise, is easy to control, and is easy to achieve automated packaging.

[0067] First embodiment

[0068] Figure 1 It is a schematic diagram of the three-dimensional structure of a packaging device provided by the first embodiment.

[0069] Figure 2 It is a schematic cross-sectional structural diagram of a packaging device provided in the first embodiment.

[0070] Figure 3 It is a schematic diagram of the partial cross-sectional structure of the packaging equipment provided by the first embodiment in the first state.

[0071] See also Figures 1 to 3 The first embodiment of the present application provides a subpackaging device 100, which includes a first carrier module 1 and a second carrier module 2. The second carrier module 2 is adapted to move toward a first direction (eg, Figure 2 a direction in the figure) and moves in a second direction away from the first carrier module 1 (such as Figure 2 b direction) activities in the .

[0072] The first supporting module 1 includes a first supporting member 11 and a guide channel 12. The first supporting member 11 is used to support the first tank body 201. One end of the guide channel 12 faces the direction of the first tank opening of the first tank body 201.

[0073] The second supporting module 2 includes a second supporting member 21 , a first opening member 22 and a second opening member 23 .

[0074] The second support member 21 is used to support the second tank body 202. The capacity of the second tank body 202 is greater than that of the first tank body 201. The second tank opening of the second tank body 202 is opposite to the other end of the guide channel 12. The second tank body 202 is used to pour liquid into the first tank body 201, thereby dispensing the liquid in the second tank body 202 into the first tank body 201.

[0075] The second opening member 23 is movable relative to the second support member 21 to open the second opening of the second tank body 202. The first opening member 22 is suitable for opening the first tank body 201, and when the second opening member 23 opens the second opening, the first opening member 22 does not contact the first opening. That is, the first support member 11 is used to support the first tank body 201 to be filled, and the second support member 21 is used to support the second tank body 202 containing the liquid to be dispensed. The second opening member 23 is used to open the second tank body 202, and the liquid in the second tank body 202 will first flow into the guide channel 12. At this time, the first opening member 22 opens the first tank body 201, allowing the liquid in the guide channel 12 to flow into the first tank body 201, thereby completing the dispensing.

[0076] Optionally, the liquid may be freon liquid, liquid nitrogen, liquid ammonia, liquid methane, etc. The type of the liquid is not limited in this embodiment.

[0077] It is worth noting that the first and second directions described above are opposite directions, with the first direction being the direction from the second support member 21 toward the first support member 11, and the second direction being the direction from the first support member 11 toward the second support member 21. To facilitate the outflow of liquid from the second tank 202, this embodiment uses the example of the second support module 2 being located directly above the first support module 1, with the first direction being the direction of gravity and the second direction being the direction opposite to the direction of gravity. Of course, in other embodiments, the first direction may also be a direction at a certain angle to the direction of gravity, which is not a limitation in this embodiment.

[0078] Figure 4 It is a schematic diagram of the partial cross-sectional structure of the packaging equipment provided by the first embodiment in the second state.

[0079] Figure 5 It is a schematic diagram of the partial cross-sectional structure of the packaging equipment provided by the first embodiment in the third state.

[0080] During packaging, the second carrier 21, the first opening member 22, and the second opening member 23 move in the first direction, gradually approaching the first carrier 11. During this approach, the second opening member 23 first contacts the first carrier 11, while the first opening member 22 does not. Supported by the first carrier 11, the second opening member 23 stops moving. However, the second carrier 21 and the first opening member 22 continue to approach the first carrier 11. This generates relative motion between the second opening member 23 and the second carrier 21. With the first carrier 11 as a reference, the second opening member 23 stops moving relative to the first carrier 11, while the second carrier 21 moves relative to the first carrier 11. At this point, the second opening member 23 and the second carrier 21 still move relative to each other. However, the second can 202 continues to move in conjunction with the second carrier 21, gradually approaching the second can opening of the second can 202.

[0081] like Figure 3 As shown, when the second opening member 23 contacts the second opening, the dispensing device 100 is in the first state. At this point, the second opening 23 opens the second opening, but the first opening 22 has not yet contacted the first opening of the first tank body 201. In other words, the first opening is in an unopened state. In the first state, the liquid in the second tank body 202 flows out under the action of gravity and into the guide channel 12 opposite the second opening of the second tank body 202. At the same time, because the first opening of the first tank body 201 is not yet opened, the liquid in the second tank body 202 remains in the guide channel 12. The guide channel 12 not only guides the liquid from the second tank body 202 to the first tank body 201, but also controls the timing of the liquid reaching the first opening of the first tank body 201 through its structural design, ensuring that the liquid flows to the first opening only after the first opening 22 opens the first opening. This ensures that the liquid flows to the first tank body 201 when the first opening of the first tank body 201 is opened, preventing leakage.

[0082] like Figure 4 As shown, when the first opening member 22 contacts the first can opening, the dispensing device 100 is in the second state. At this point, the first opening member 22 contacts the first can opening, but the first opening member 22 does not open the first can body 201. In other words, the first can opening has not yet been opened, and the second state is an intermediate state. At this point, the liquid in the second can body 202 remains in the guide channel 12 and gradually flows toward the location of the first can body 201.

[0083] like Figure 5As shown, when the first opening member 22 opens the first tank opening, the subpackaging device 100 is in the third state. At this time, the liquid in the guide channel 12 flows into the first tank body 201 under its own gravity, thereby achieving liquid subpackaging.

[0084] The packaging device 100 provided in this embodiment opens the second tank body 202 and the first tank body 201 in sequence through the second opening member 23 and the first opening member 22, and uses the guide channel 12 to control the flow direction and flow duration of the liquid to prevent liquid leakage. During the packaging process, since the second carrier module 2 is located above the first carrier module 1, the flow of the liquid in the second tank body 202 only needs to rely on its own gravity to flow into the first tank body 201, and does not require negative pressure or vacuum pressure drive, so as to avoid the use of pneumatic equipment, thereby simplifying the structure of the packaging device 100. In this way, the packaging noise can also be reduced. At the same time, since the pneumatic equipment is not easy to control, in the packaging process of the present application, it is only necessary to control the second carrier module 2 to gradually approach the first carrier module 1 to achieve packaging. This process is easy to control and easy to implement automated control, which can effectively improve the packaging accuracy and packaging efficiency.

[0085] Furthermore, in conventional packaging methods, the first and second opening members can be opened simultaneously, allowing the liquid in the second tank to flow directly into the first tank. In this case, the packaging equipment's first opening member must contact the first tank opening while the second opening member also contacts the second tank opening. The design of the equipment not only requires limiting the relative dimensions of the first and second opening members to ensure structurally simultaneous opening, but also requires simultaneous control, which requires high control precision and is difficult to manufacture. In this embodiment, during packaging, the second opening member 23 and the first opening member 22 operate sequentially, opening the second and first tank openings in sequence. This allows the first opening member 22 to open the first tank opening after the second opening member 23 opens the second tank opening, facilitating step-by-step control and reducing the control precision required. Furthermore, the second opening member 23 opening the second tank opening and the first opening member 22 opening the first tank opening can operate independently, eliminating the need for a linkage design. This allows for greater design freedom for the first and second opening members 22, 23, reducing the complexity of equipment design and manufacturing.

[0086] The first carrier module 1 and the second carrier module 2 are introduced below respectively.

[0087] Figure 6 It is a schematic cross-sectional structural diagram of the first carrier module and the temperature adjustment module provided in the first embodiment.

[0088] Figure 7 It is a schematic top view of the first supporting module and the temperature adjustment module provided in the first embodiment.

[0089] The following combination Figure 6 and Figure 7 , the specific structure of the first carrier module 1 is exemplarily described. The first carrier module 1 may include at least: a first carrier 11 and a guide channel 12. Below, each component of the first carrier module 1 is introduced respectively.

[0090] like Figure 6 As shown, in some embodiments, the first carrier 11 may include at least one accommodating cavity 111, the shape of the accommodating cavity 111 is adapted to the shape of the first can body 201, and the size of the accommodating cavity 111 is adapted to the size of the first can body 201, so that when repackaging, the first can body 201 can be placed in the accommodating cavity 111 to achieve the support of the first can body 201.

[0091] Optionally, the number of the accommodating cavities 111 is at least one, and accordingly, the number of the first tank bodies 201 that the first carrier 11 can carry is at least one, for example: the first tank bodies 201 can be two, four, ten, or even more. In this embodiment, there is no limitation on the number of the accommodating cavities 111 and the first tank bodies 201 that the first carrier 11 can carry.

[0092] like Figure 6 As shown, in one implementation, the first tank body 201 is cylindrical in shape, and accordingly, the accommodating cavity 111 is also cylindrical; and the size of the accommodating cavity 111 is just enough to accommodate the first tank body 201, and supports the first tank body 201 to be taken out of the accommodating cavity 111, or placed into the accommodating cavity 111 from the outside.

[0093] In addition, the shape of the first tank body 201 may also be other shapes, and accordingly, the accommodating cavity 111 may also be adaptively changed to other shapes. This embodiment does not limit the size and shape of the first tank body 201 and the accommodating cavity 111.

[0094] In other embodiments, the shape of the accommodating cavity 111 is adapted to the shape of the bottom of the first can body 201, and the size of the accommodating cavity 111 is adapted to the size of the bottom, so that when repackaging, the bottom of the first can body 201 is placed in the accommodating cavity 111 to support the first can body 201. In this case, the upper portion of the first can body 201 is exposed outside the accommodating cavity 111. The bottom of the first can body 201 can be the portion below the cross-section bisected by the cross-section at the middle of the first can body 201; or, it can be the portion below the cross-section bisected by the cross-section at a preset distance from the bottom surface of the first can body 201. This embodiment does not limit the setting method of the bottom.

[0095] like Figure 7As shown, in one implementation, when there are at least two accommodating cavities 111, each accommodating cavities 111 can be evenly distributed around the central axis of the first carrier 11. For example, the first carrier 11 can be cylindrical, and the accommodating cavities 111 are evenly arranged three times around the central axis of the first carrier 11. When there is only one accommodating cavity 111, the central axis of the accommodating cavity 111 coincides with the central axis of the first carrier 11.

[0096] In other embodiments, the accommodating cavities 111 may also be distributed on the first carrier 11 in other ways, which will not be described in detail in this embodiment.

[0097] like Figure 6 As shown, when the first tank body 201 is mounted on the first support member 11, the first opening of the first tank body 201 is exposed and faces the second support module 2. A first tank body sealing portion is provided at the first opening to seal the first tank body 201. Optionally, the first tank body sealing portion may be a valve body, a sealing film, a sealing plug, etc. This embodiment does not limit the implementation of the first tank body sealing portion.

[0098] In this embodiment, the second tank body 202 is opened before the first tank body 201. To prevent leakage of liquid from the second tank body 202 when the second opening of the second tank body 202 is open but the first opening of the first tank body 201 is not, a guide channel 12 is provided on the first carrier 11. During the filling process, the guide channel 12 is located between the second opening and the first opening to control the direction and flow rate of the liquid while the second opening is open but the first opening is not.

[0099] Continue reading Figure 6 and Figure 7 In some embodiments, the guide channel 12 includes a converging portion 121 and a diverting channel 122 connected to the converging portion 121. The converging portion 121 is used to converge the liquid flowing out of the second tank body 202 during the subpackaging process; the diverting channel 122 is used to divert the liquid gathered by the converging portion 121 to the first tank opening, so as to flow into the first tank body 201 through the first tank opening.

[0100] The position of the converging portion 121 on the first carrying module 1 enables the converging portion 121 to be opposite to the second tank opening of the second tank body 202 during subpackaging.

[0101] Exemplarily, the top of the first carrying module 1 faces the second tank opening, and the converging portion 121 can be located on the top of the first carrying module 1. In this way, when the liquid is packaged, the converging portion 121 can be opposite to the second tank opening of the second tank body 202.

[0102] In one example, if the second tank opening is opposite to the center of the first carrier module 1 , the convergence portion 121 may be disposed at the center of the top of the first carrier module 1 to be opposite to the second tank opening.

[0103] In another example, if the second tank opening is eccentrically disposed relative to the first supporting module 1 , the converging portion 121 may be disposed at an eccentric position on the top of the first supporting module 1 and opposite to the second tank opening in the direction of gravity.

[0104] like Figure 7 As shown, in one implementation, the converging portion 121 may include a converging groove disposed on the first carrier 11, with the diverter channel 122 communicating with the converging groove and extending toward the first tank opening. To facilitate communication with the diverter channel 122, the converging groove may be annular. In this case, multiple diverter channels 122 may be distributed around the periphery of the annular converging groove, thereby diverting the liquid in the converging groove to each diverter channel 122.

[0105] In another implementation, the converging portion 121 may include a converging hole provided on the first carrier 11, or a funnel-shaped structure, etc., to achieve the convergence of the liquid. It is understood that the converging portion 121 provided in this embodiment is a structure for converging the liquid into one place, and it can also be achieved by other components, which are not listed here in this embodiment.

[0106] There is at least one diverting channel 122. If the first carrier 11 can support at least two first tanks 201 and there is only one diverting channel 122, the first carrier 11 can rotate about its central axis to mate the diverting channel 122 with each first tank 201. In this case, liquid can only be dispensed into one first tank 201 at a time.

[0107] Optionally, in order to improve the packaging efficiency, when the first carrier 11 can carry at least two first tank bodies 201, the number of diversion channels 122 is also at least two, and one end of each diversion channel 122 is connected to the convergence part 121, and the other end extends toward the direction of the first tank body 201.

[0108] It is worth noting that the design of the diversion channel 122 is to facilitate the dispersion of the liquid in the converging portion 121 in various directions, so as to facilitate the diversion of the liquid to the positions of the first tank bodies 201, thereby improving the packaging efficiency. The direction of the first tank body 201 refers to the direction of the distribution shape formed by the various first tank bodies 201 relative to the converging portion 121. For example: Figure 7The first tank bodies 201 are connected to form a distribution shape including three rings with the same center and different radii. The diverter channel 122 extends from the converging portion 121 toward the rings. In this case, the diverter channel 122 can extend in the direction directly opposite the location of a first tank body 201 and / or in the direction directly opposite a gap between two adjacent first tank bodies 201.

[0109] In this way, the diversion channel 122 can divert the liquid in the converging portion 121 to different directions, so that the liquid in the converging portion 121 can be dispersed in various directions at the same time, thereby facilitating the liquid to flow to each first tank body 201 .

[0110] In addition, in order to ensure that the diverter channels 122 evenly guide the liquid in the converging portion 121, the diverter channels 122 are evenly arranged around the converging portion 121. At the same time, the extension direction of the diverter channels 122 can be directly facing the direction where the first tank body 201 is located, or directly facing the gap between the two first tank bodies 201.

[0111] refer to Figure 7 Taking four diversion channels 122 as an example, the four diversion channels 122 can be evenly arranged, that is, a 90° angle can be formed between two adjacent diversion channels 122. The number of first tank bodies 201 is far more than four. In order to achieve a reasonable arrangement of the first tank bodies 201, the first tank bodies 201 are arranged in multiple rings.

[0112] In one implementation, to facilitate the diversion of the liquid in the converging portion 121 to the various first tank bodies 201, one end of each of the four diversion channels 122 is connected to the converging portion 121, and the four diversion channels 122 extend in directions facing different first tank bodies 201. This facilitates the diversion of the liquid in the converging portion 121 to the locations of the various first tank bodies 201, and transfers the liquid through the first tank bodies 201 arranged in the inner ring to the first tank bodies 201 in the middle and outer rings, thereby achieving dispersed flow of the liquid and improving packaging efficiency.

[0113] In another implementation, the extension direction of the four diversion channels 122 is directly opposite to the position of the gap between two adjacent first tank bodies 201 on each ring. In this way, the dispersed flow of the liquid can be achieved and the packaging efficiency can be improved.

[0114] It is worth noting that the number of diverter channels 122 can be equal to the number of first tank bodies 201, or the number of diverter channels 122 can be different from the number of first tank bodies 201. In other embodiments, the number of diverter channels 122 can be adjusted according to the number of first tank bodies 201. Furthermore, the extension direction of the diverter channels 122 can also be adjusted according to the arrangement of the first tank bodies 201. In this embodiment, the number and extension direction of the diverter channels are not limited.

[0115] Optionally, see Figure 6 and Figure 7 To facilitate the formation of the diversion channel 122 and the converging portion 121, a boss 132 structure can be provided on the first carrier module 1. A groove is provided in the middle of the boss 123 to form the converging portion 121, and a channel is provided on the boss 123, which connects the groove and the periphery of the boss 123 to form the diversion channel 122.

[0116] It is worth noting that the grooves and channels provided on the boss 123 may be achieved by etching or cutting, which is not specifically limited in this embodiment.

[0117] refer to Figure 7 Optionally, the shape of the boss 123 can be a cylindrical boss, the converging portion 121 can be set at the center of the boss 123, and the diversion channel 122 can be radially dispersed from the converging portion 121 to facilitate radial dispersion of the liquid in the converging portion 121, thereby improving the packaging efficiency.

[0118] Optionally, the boss 123 can be provided separately from the first carrier 11. In this case, a receiving groove can be provided on the first carrier 11 to accommodate the boss 123, thereby enabling installation of the boss 123. This facilitates replacement of the boss 123, thereby facilitating inspection and maintenance of the packaging device 100. Furthermore, the separate structure of the boss 123 and the first carrier 11 also facilitates the use of different materials. The boss 123 can be made of a material with greater rigidity to resist deformation, extend service life, and reduce the difficulty of manufacturing the first carrier module.

[0119] In other embodiments, the boss 123 may also be integrated with the first carrier 11 . This embodiment does not limit the connection method between the boss 123 and the first carrier 11 .

[0120] Optionally, there is a certain distance between the end of the diversion channel 122 facing the first tank opening and each first tank opening, for example: Figure 7, the end of the diverter channel 122 facing the first tank opening is not connected to the first tank openings of the inner ring, but there is a certain distance between them. At this time, the liquid flowing out of the diverter channel 122 may flow to any position randomly, and there is a situation where a large amount of liquid cannot enter the first tank body 201, resulting in the problem of reduced packaging efficiency of the first tank body 201. Based on this, in this embodiment, the guide channel 12 can also include an inter-tank channel 124 for connecting the first tank openings of multiple first tank bodies 201 and surrounding the diverter channel 122. The provision of the inter-tank channel 124 enables two adjacent first tank bodies 201 to be interconnected, thereby achieving mutual communication between multiple first tank bodies 201, and at the same time being distributed around the diverter channel 122. In this way, the liquid randomly scattered everywhere can be guided back into the first tank body 201 through the inter-tank channel 124, thereby improving the packaging efficiency of the first tank body 201.

[0121] In one implementation, reference Figure 7 The inter-tank channel 124 may be a groove structure provided on the surface of the first carrier 11 facing the first opening member 22 , so that the groove can be easily formed during the molding and manufacturing process.

[0122] In another embodiment, the inter-tank passage 124 may be a hole structure that connects the openings of the multiple first tanks 201. The hole structure may be provided inside the first carrier 11 to form a pipe structure inside the first carrier 11, thereby connecting the multiple first tank openings.

[0123] Optionally, there is one or at least two inter-tank passages 124. When there are at least two inter-tank passages 124, each inter-tank passage 124 connects to the first tank openings of some first tanks 201, and different inter-tank passages 124 connect to the first tank openings of different first tanks 201. When there is only one inter-tank passage 124, it connects to the first tank openings of all first tanks 201.

[0124] Optionally, the inter-tank channels 124 may be arranged in a straight line, a rectangle, or a circle, etc. This embodiment does not limit the arrangement shape of the inter-tank channels 124 . Figure 7 In the figure, the example in which there are three inter-tank passages 124 and each inter-tank passage 124 is circular, has the same center, and is arranged in ascending order of radius is used for description.

[0125] Optionally, in order to ensure that the liquid in the guide channel 12 can flow evenly into each first tank body 201, the accommodating cavities 111 in the first carrier 11 are arranged around the guide channel 12. In other words, the accommodating cavities 111 in the first carrier 11 are evenly arranged around the central axis of the guide channel 12. For example: Figure 7In the embodiment, each accommodating cavity 111 is evenly arranged in three circles with the center of the converging portion 121 in the guide channel 12 as the central axis.

[0126] Optionally, the guide channel 12 may be integrated with the first carrier 11 or may be independent components. This embodiment does not limit the connection method between the guide channel 12 and the first carrier 11.

[0127] Figure 8 It is a schematic cross-sectional structural diagram of the first carrying module, the temperature adjustment module and the second driving module provided in the first embodiment.

[0128] Please combine Figure 2 and Figure 8 Optionally, the first carrier module 1 is fixed, or the first carrier module 1 is movable. In the case where the first carrier module 1 is movable, the packaging device 100 further includes a second driving module 3 connected to the first carrier module 1 .

[0129] The second driving module 3 is used to drive the first carrying module 1 in a direction perpendicular to the first direction and the second direction (eg Figure 8 For example, the second driving module 3 can drive the first carrying module 1 to move closer to the sub-packaging station (such as Figure 8 c direction in the figure) and leaving the subpackaging station (e.g. Figure 8 d direction in the figure), thereby facilitating the first carrying module 1 to install the first tank body 201 and remove the first tank body 201 at other stations.

[0130] See also Figure 8 Optionally, the second driving module 3 may include a slide 31 and a slide rail 32 . The slide 31 may be slidably connected to the slide rail 32 , and the slide 31 is used to receive the first carrying module 1 to drive the first carrying module 1 to move along the slide rail 32 .

[0131] In one implementation, since the first carrier module 1 needs to receive the first tank body 201, and when the second carrier module 2 approaches the first carrier module 1, the first carrier 11 also needs to support the second opening member 23. Therefore, the first carrier 11 will be subjected to a certain pressure, and this pressure will act on the slide 31 and the slide rail 32. At this time, the slide 31 can be a ball screw slide 31. The ball screw slide 31 has better load-bearing capacity, can reduce the possibility of deformation of the slide 31 and the slide rail 32 when subjected to external force, and has higher reliability. At the same time, in the process of subpackaging the liquid, the first carrier module 1 and the second carrier module 2 need to be aligned, and the ball screw slide 31 and the slide rail 32 have higher travel accuracy, which makes it easier to control the position of the first carrier module 1 for subpackaging.

[0132] In another embodiment, the second driving module 3 may also include a rope and a pulley. The rope is used to connect the first supporting module 1 and drive the first supporting module 1 to move along the pulley. The pulley can be a fixed pulley or a movable pulley, which is not limited in this embodiment.

[0133] See also Figure 8 Optionally, to facilitate driving the slide 31, the second driving module 3 may further include a power source 33. The power source 33 is connected to the slide 31 and can drive the slide 31 to move along the slide rail 32, thereby driving the slide 31 to drive the first supporting module 1 to move along the slide rail 32. The power source 33 may be a servo motor, a motor, or the like.

[0134] In other examples, the slide 31 may also be manually driven to simplify the packaging device 100. When manually driven, the slide 31 may be directly pushed to move along the slide rail 32.

[0135] It is worth noting that the structure of the second driving module 3 provided above is only an example, and it may also be a telescopic rod, a transmission chain structure, etc., which is not limited in this embodiment.

[0136] Please combine Figures 6 to 8 Optionally, the packaging device 100 may further include a temperature regulating module 4. The temperature regulating module 4 is disposed within the first carrier module 1 to regulate the temperature of the first carrier module 1. Some liquids, such as Freon and liquid nitrogen, tend to vaporize at room temperature. To prevent the liquid from vaporizing when flowing out of the second tank 202, the temperature regulating module 4 can provide a low-temperature environment during the packaging process, enabling packaging in a liquid state.

[0137] During packaging, the temperature regulating module 4 can maintain a low-temperature environment for the first tank 201 carried by the first carrier 11, and can also maintain a low-temperature environment around the first carrier 11. This allows the liquid to be packaged to be packaged in a liquid state, reducing packaging difficulty and improving packaging efficiency.

[0138] Optionally, see Figure 6 The temperature regulating module 4 may include a temperature regulating component 41, which is disposed on the first carrier 11. The temperature regulating component 41 can cool and heat to regulate the temperature of the first carrier 11. For example, the temperature regulating component 41 may be disposed on a side wall of the first carrier 11 (e.g., Figure 6 As shown in FIG, or the temperature adjustment component 41 can be arranged at the bottom of the first carrier 11. In this embodiment, the arrangement position of the temperature adjustment component 41 is not limited.

[0139] It is worth noting that the temperature adjustment components 41 can be a single group or multiple groups. If multiple groups are provided, the multiple groups of temperature adjustment components 41 can all be disposed on the sidewalls of the first carrier 11; or some can be disposed on the sidewalls of the first carrier 11 and some can be disposed on the bottom of the first carrier 11.

[0140] In one implementation, the temperature adjustment component 41 may include a control unit and a semiconductor temperature adjustment unit. The semiconductor temperature adjustment unit has both cooling and heating functions. The control unit is used to control the cooling or heating of the semiconductor temperature adjustment unit to facilitate automatic control.

[0141] In another implementation, the temperature adjustment component 41 may also include a condenser for cooling and a heater for heating, wherein the condenser and the refrigerator may be respectively arranged at different positions or at the same position.

[0142] See also Figure 6 Optionally, the temperature adjustment module 4 may further include a heat conducting component 42 connected to the temperature adjustment component 41. When cooling the first carrier 11, the heat conducting component 42 may be used to conduct the heat of the first carrier 11 and the heat generated by the temperature adjustment component 41 during operation to the air, thereby improving the cooling efficiency.

[0143] In one implementation, the heat conducting component 42 may include a plurality of heat conducting pipes (such as Figure 7 As shown in FIG, the heat pipe extends from the temperature regulating assembly 41 toward the periphery to extend into the air. In this way, the contact area between the heat pipe and the air can be increased, which facilitates heat conduction.

[0144] In another implementation, the heat conducting assembly 42 may include multiple sets of heat conducting plates, each of which is connected to the temperature regulating assembly 41. The heat conducting plates may have a higher thermal conductivity than the temperature regulating assembly 41 to facilitate heat conduction. Furthermore, the heat conducting plates may be coated with a thermally conductive gel or the like to improve heat conduction efficiency.

[0145] See also Figure 6 Optionally, the temperature regulating module 4 may further include a heat dissipation component 43 , which is connected to the heat conduction component 42 to further improve the cooling efficiency.

[0146] In one implementation, the heat dissipation assembly 43 may include a heat dissipation fan (e.g. Figure 7 As shown, a cooling fan is connected to the heat conducting assembly 42. The cooling fan blows air to quickly remove heat from the heat conducting assembly 42, thereby improving cooling efficiency. The number of cooling fans can be one or more, and can be adjusted based on actual conditions.

[0147] In another implementation, the heat dissipation component 43 may include heat dissipation fins connected to the heat conduction component 42. The heat dissipation fins further increase the contact area between the heat conduction component 42 and the air, thereby improving the cooling efficiency.

[0148] In other implementations, the heat dissipation assembly 43 may include a heat dissipation fan and heat dissipation fins. The heat dissipation fins are connected to the heat conduction assembly 42. The heat dissipation fan may be provided on the heat dissipation fins or on the heat conduction assembly 42, which is not limited here.

[0149] See also Figure 6 Optionally, in order to facilitate temperature control of the first carrier 11, the packaging device 100 further includes a temperature detection module 5 in communication with the temperature adjustment module 4. The temperature detection module 5 is provided on the first carrier 11 to detect the temperature of the first carrier 11, thereby facilitating temperature control.

[0150] like Figure 6 As shown, in one implementation, the temperature detection module 5 is disposed in the middle of the first carrier 11. Since the middle of the first carrier 11 is farther away from the temperature adjustment module 4, when the temperature in the middle of the first carrier 11 reaches the required value, the temperatures in other locations of the first carrier 11 can also reach the required value.

[0151] In another implementation, the temperature detection module 5 can also be disposed on the side wall of the first carrier 11 to facilitate connection. In this embodiment, the location of the temperature detection module 5 is not limited.

[0152] Optionally, the temperature detection module 5 may include a temperature sensor to facilitate temperature detection, wherein the temperature sensor may be a thermocouple, a thermistor, an infrared temperature sensor, etc., which is not limited in this embodiment.

[0153] Optionally, the temperature detection module 5 may further include a temperature sensor and a controller, etc. The controller is coupled to the temperature sensor and the temperature adjustment module 4 to facilitate automatic temperature setting.

[0154] See also Figure 8 Optionally, a heat insulation structure 6 is further provided between the second driving module 3 and the first carrier 11. Since the first carrier 11 needs to be connected to the second driving module 3. When the packaging device 100 has a temperature adjustment module 4, in order to prevent the cooling or heat of the first carrier 11 from being dissipated into the air through the second driving module 3 when the temperature of the first carrier 1 is controlled, the heat insulation structure 6 can reduce the influence of the second driving module 3 on the temperature of the first carrier 11, thereby facilitating the temperature control of the first carrier 11 and saving energy.

[0155] like Figure 8 As shown, in one implementation, the heat insulating structure 6 may be a heat insulating gasket located between the first supporting member 11 and the slide 31. The heat insulating gasket may be a heat insulating gasket such as a silicone gasket or a rubber gasket.

[0156] In another implementation, the thermal insulation structure 6 may be a thermal insulation coating located between the first carrier 11 and the slide 31 . The thermal insulation structure 6 is not limited in this embodiment.

[0157] Figure 9 It is a schematic diagram of the partial structure of the packaging equipment provided by the first embodiment in the fourth state.

[0158] Figure 10 It is a partial structural diagram of the second tank body, the second carrying module and the first driving module provided by the first embodiment.

[0159] Figure 11 yes Figure 10 Enlarged view of part A in .

[0160] The following combination Figures 9 to 11 , the specific structure of the second carrier module 2 is exemplarily described. The second carrier module 2 may include at least a second carrier 21, a first opening member 22, and a second opening member 23. The following describes each part of the second carrier module 2.

[0161] The second supporting member 21 is used to support the second tank. Figure 11 The second carrier 21 is provided with a mounting hole 213, which is opposite to the second tank opening. When the second tank opening is opened, the mounting hole 213 corresponds to the second tank opening, and the mounting hole 213 can guide the liquid in the second tank body 202 to the guide channel 12.

[0162] Alternatively, as Figure 9 As shown, in some embodiments, the second carrier 21 has a receiving groove 211 that opens toward the first carrier 11. When the second carrier 21 moves in a first direction, the first carrier 11 enters the receiving groove 211 from the opening of the receiving groove 211. The receiving groove 211 is used to accommodate the first carrier 11, thereby facilitating alignment of the first carrier 11 and the second carrier 21.

[0163] In one implementation, the shape of the receiving groove 211 matches the shape of the first carrier 11 .

[0164] For example, when the first carrier 11 is cylindrical, the receiving groove 211 is also cylindrical. The dimensions of the receiving groove 211 are adapted to those of the first carrier 11. For example, the receiving groove 211 can precisely accommodate the first carrier 11, so that when the second carrier 21 approaches the first carrier 11, the receiving groove 211 can gradually accommodate the first carrier 11.

[0165] It's worth noting that during subpackaging, as the second carrier 21 approaches the first carrier 11, the first carrier 11 enters the receiving groove 211 of the second carrier 21. If the dimensions of the first carrier 11 match those of the receiving groove 211, the first carrier 11 can, to a certain extent, seal the receiving groove 211. This creates a sealed cavity between the first carrier 11 and the second carrier 21, facilitating sealed subpackaging.

[0166] In another implementation, the shape of the receiving groove 211 is different from the shape of the first carrier 11 .

[0167] For example, when the first carrier 11 is cylindrical, the receiving groove 211 may be square. The receiving groove 211 needs to be large enough to accommodate the first carrier 11 so that the second carrier 21 can gradually accommodate the first carrier 11 when the second carrier 21 approaches the first carrier 11.

[0168] It is worth noting that when the receiving groove 211 of the second carrier 21 has a different shape from that of the first carrier 11, a gap will be formed at the sidewall between the first carrier 11 and the receiving groove 211. In this case, if a seal is required between the first carrier 11 and the receiving groove 211, an additional sealing component will be required.

[0169] See also Figure 10 Optionally, the second carrier 21 further has a recovery channel 212 to utilize the recovery channel 212 to recover the liquid that overflows the guide channel 12 or remains on the first carrier 11 .

[0170] The recycling process is as follows:

[0171] like Figure 9 As shown, Figure 9 Figure 2 shows the first opening member 22 positioned away from the first can opening. After the liquid in the second can 202 is dispensed, the first opening member 22, driven by the second carrier 21, gradually moves away from the first can opening. When the first opening member 22 leaves the first can opening, if the first can opening has a sealing valve, the first can opening automatically closes. This allows the first can 201 to seal the liquid within.

[0172] like Figure 9As shown, the first carrier 11 and the guide channel 12 may have overflowed liquid to be dispensed. When the second carrier 21 moves away from the first carrier 11, the first carrier 11 will continue to be in the receiving groove 211 for a period of time. During this period of time, the first carrier 11 blocks the notch of the receiving groove 211, thereby forming a sealed cavity between the first carrier 11 and the second carrier 21 (as shown in FIG. Figure 9 The overflowed liquid to be packaged will be in the sealed cavity. At this time, the recovery channel 212 can be connected to the sealed cavity of the second carrier 21, thereby realizing the recovery of the liquid to be packaged.

[0173] Please continue reading Figure 9 and Figure 10 Optionally, the recovery channel 212 includes a first end 2121 and a second end 2122. After the first can 201 is packaged and the first opening member 22 is removed from the first can opening, the first end 2121 is connected to the sealed cavity, and the second end 2122 is used to connect to a recovery component (not shown).

[0174] like Figure 9 As shown, it is worth noting that in the receiving groove 211, at the top of the first carrier 11, the distributed several horizontal lines are the projection lines of the annular groove structure provided on the side wall of the receiving groove 211. Figure 9 As shown, specifically, after the subpackaging is completed, the second carrier 21 can be moved a certain distance along the second direction so that the first carrier 11 is still in the receiving groove 211, so that a sealed cavity still exists between the first carrier 11 and the second carrier 21. When the first carrier 11 moves relative to the receiving groove 211 until the first end 2121 is connected to the sealed cavity, as shown in FIG. Figure 9 At this position, the remaining liquid in the sealed cavity can flow from the first end 2121 to the second end 2122, and finally to the recovery component for recovery. The remaining liquid in the sealed cavity includes the liquid remaining in the converging portion 121, the diverting channel 122, the inter-tank channel 124, and the surface of the first carrier 11.

[0175] like Figure 5 As shown, it is worth noting that during subpackaging, the position of the first carrier 11 relative to the receiving groove 211 can block the first end 2121, as shown in FIG. Figure 5 The first carrier 11 is positioned relative to the receiving groove 211. At this time, the sealed cavity is sealed, and the liquid can only flow along the converging portion 121, the diverter channel 122, the inter-tank channel 124 and the surface of the first carrier 11 to the first tank 201.

[0176] Optionally, the recovery channel 212 may be a channel provided on the sidewall of the receiving groove 211. That is, the recovery channel 212 is formed by punching holes on the sidewall of the receiving groove 211.

[0177] like Figure 9 As shown, in one implementation, the first end 2121 of the recovery channel 212 is connected to the sealed cavity, and the second end 2122 can be located in a second direction relative to the first end 2121 , that is, the second end 2122 is located above the first end 2121 .

[0178] At this time, the liquid to be packaged in the sealed cavity cannot flow autonomously from the first end 2121 to the second end 2122. For example, the recovery component may have a certain suction force at this time, thereby being able to suck out the remaining liquid to be packaged.

[0179] Alternatively, the temperature regulating assembly 41 can be used to heat the first carrier 11 to increase the temperature in the sealed cavity, thereby vaporizing the remaining liquid to be packaged, which can then flow from the first end 2121 to the second end 2122 for easy recovery.

[0180] In another implementation, the first end 2121 of the recovery channel 212 is connected to the sealed cavity, and the second end 2122 can be located in a first direction relative to the first end 2121. That is, the second end 2122 is located below the first end 2121. In this case, the liquid to be packaged in the sealed cavity can flow autonomously from the first end 2121 to the second end 2122, facilitating recovery.

[0181] It is understood that the recovery component can be a recovery tank connected by a pipe, or a recovery tank directly provided at the second end 2122. Alternatively, the recovery component can also have a certain suction force to facilitate recovery. The specific structure of the recovery component is not limited in this embodiment.

[0182] The second opening member 23 is mounted on the second supporting member 21 to facilitate opening the second tank opening.

[0183] Optionally, during subpackaging, the second opening member 23 can pass through the mounting hole 213 and be easily movable in the mounting hole 213. In this way, the mounting hole 213 can not only guide the liquid in the second tank body 202, but also limit the movable direction of the second opening member 23 to facilitate opening the second tank mouth.

[0184] It is understandable that, in other embodiments, when subpackaging is not performed, the second opening member 23 may not be located in the mounting hole 213. When subpackaging begins, the second opening member 23 may move into the mounting hole 213.

[0185] Optionally, the second opening member 23 includes an opening end and a supporting end. During subpackaging, the opening end faces the installation position of the second can opening to open the second can opening, and the supporting end faces the first carrier 11 to support the first carrier 11.

[0186] When the second carrier 21 gradually approaches the first carrier 11, the abutting end of the second opening member 23 first contacts the first carrier 11. Since the first carrier 11 is fixed and the second carrier 21 moves toward the first carrier 11, the first carrier 11 will support the second opening member 23. When the second carrier 21 further approaches the first carrier 11, the second opening member 23 that contacts the first carrier 11 will move in the second direction relative to the mounting hole 213 (such as Figure 4 In this way, the second opening member 23 moves closer to the second can body 202 relative to the mounting hole 213, so as to open the second can body 202 through the opening end.

[0187] For example, the second opening member 23 may be a needle-shaped structure. The abutting end of the second opening member 23 may be a plane to facilitate contact with the first carrier 11. The opening end of the second opening member 23 may be a cone-shaped structure to facilitate puncturing the second can opening.

[0188] See also Figure 9 Optionally, the first opening member 22 is arranged on the bottom surface of the accommodating groove 211. During subpackaging, the opening end of the first opening member 22 faces the installation position of the first can mouth.

[0189] like Figure 9 As shown, in one implementation, the first opening member 22 can be fixedly connected to the bottom surface of the receiving groove 211 by bolts. While achieving the fixation of the first opening member 22, it can also be easy to disassemble and replace.

[0190] In another implementation, the first opening member 22 may be connected to the bottom surface of the accommodating groove 211 by gluing.

[0191] In one implementation, to facilitate the sequential movement of the second opening member 23 and the first opening member 22 as the second carrier 21 gradually approaches the first carrier 11, the abutting end of the second opening member 23 protrudes beyond the opening end of the first opening member along the movement direction. This allows the abutting end of the second opening member 23 to contact the first carrier 11 first, allowing the second opening member 23 to move relative to the second carrier 21 first and open the second can opening.

[0192] In another embodiment, to facilitate the sequential movement of the second opening member 23 and the first opening member 22 as the second carrier 21 gradually approaches the first carrier 11, the abutting end of the second opening member 23 is aligned with the opening end of the first opening member along the movement direction. Simultaneously, a protrusion is provided on the first carrier 11 corresponding to the abutting end of the second opening member 23. This ensures that the abutting end of the second opening member 23 first contacts the protrusion of the first carrier 11, allowing the second opening member 23 to initially move relative to the second carrier 21 and open the second can opening. Optionally, the protrusion is formed with the aforementioned guide channel 12.

[0193] As the second carrier 21 gradually approaches the first carrier 11, the first opening member 22 can follow the second carrier 21 and gradually approach the first can 201 until the first can 201 is opened. In this way, there is no need to provide an additional power structure to drive the second opening member 23, which can help simplify the structures of the first carrier module 1 and the second carrier module 2.

[0194] Optionally, the number of first opening members 22 matches the number of first can bodies 201 . For example, when there is one first can body 201 , there is one first opening member 22 ; when there are multiple first can bodies 201 , the number of second opening members 23 is equal to the number of first can bodies 201 .

[0195] In addition, when there are multiple first can bodies 201 , the arrangement of the multiple first opening members 22 is the same as the arrangement of the first can bodies 201 .

[0196] For example, when the plurality of first can bodies 201 are arranged in a ring shape, the plurality of first opening members 22 are also arranged in a ring shape.

[0197] like Figure 9 As shown, in one embodiment, the first tank body 201 is a tank body with a built-in valve, which can automatically close the first tank opening. The valve can move relative to the first tank opening under the action of an external force to open the first tank opening. When the external force disappears, the valve can automatically reset to close the first tank opening. Accordingly, the first opening member 22 can be a columnar structure. The first opening member 22 is flat toward the valve of the first tank body 201, thereby increasing the contact area between the first opening member 22 and the valve of the first tank opening, so as to facilitate pushing open the valve of the first tank body 201 and then opening the first tank opening.

[0198] In another embodiment, when the first opening of the first can body 201 is sealed with a film, the first opening member 22 may be a cone-shaped structure, so that the tip of the cone 22 pierces the film of the first opening, thereby opening the first opening. It should be understood that the above-described structure of the first opening member 22 is merely an example and is not intended to be limiting in this embodiment.

[0199] In this example, see Figure 11 The second opening member 23 has a through hole 231 extending along the first direction. When the second opening member 23 opens the second tank opening, the liquid in the second tank body 202 flows along the through hole 231 to the guide channel 12, thereby preventing the liquid from leaking.

[0200] In one implementation, in order to quickly drain the liquid from the second tank 202, the second opening member 23 may be provided with a plurality of through holes 231. The plurality of through holes 231 may be spaced apart around the central axis of the second opening member 23 to increase the flow rate of the liquid and improve the packaging efficiency.

[0201] In another implementation, there may be only one through hole 231. The through hole 231 may be eccentrically arranged, that is, arranged at a position deviating from the central axis of the second opening member 23, so as to reduce the influence on the opening of the second tank opening.

[0202] like Figure 11 As shown, in one implementation, when the first can opening of the second can body 202 is in a film-sealed state, the second opening piece 23 can be a cone-shaped structure, so that the tip can pierce the packaging film of the second can opening, thereby opening the second can opening.

[0203] In another implementation, when the second tank body 202 is equipped with a built-in valve for closing the second tank opening, the second opening member 23 may be a columnar structure. The portion of the second opening member 23 facing the valve of the second tank body 202 is flat, thereby increasing the contact area between the second opening member 23 and the valve of the second tank opening, thereby facilitating the opening of the second tank body 202 by pushing open the valve. It should be understood that the aforementioned structure of the first opening member 22 is merely illustrative and is not intended to be limiting in this embodiment.

[0204] See also Figure 11 Optionally, the second supporting module 2 further includes a reset member 24. The reset member 24 is sleeved on the second opening member 23. Thus, after the second opening member 23 moves toward the second tank body 202 under the support of the first supporting member 11, when the second supporting member 21 moves away from the first supporting member 11, the second opening member 23 can automatically reset itself away from the installation position of the second tank opening under the action of the reset member 24, facilitating the next filling operation.

[0205] like Figure 11As shown, in one implementation, the reset member 24 can be a compression spring. If the second opening member 23 is always located in the mounting hole 213, a spring ring groove 214 is further provided in the mounting hole 213, and the compression spring is engaged with and located in the spring ring groove 214. The second opening member 23 is passed through the compression spring, and the side of the compression spring away from the second can body 202 is connected to the second opening member 23. When the compression spring is in a natural state, the second opening member 23 has not reached the installation position of the second can mouth. When the second opening member 23 moves toward the second can mouth relative to the mounting hole 213, the compression spring will be compressed. When the second carrier 21 is away from the first carrier 11, the elastic force generated by the compression of the compression spring causes the second opening member 23 to move away from the second can mouth, thereby driving the second opening member 23 to reset until the compression spring returns to its natural state.

[0206] In another implementation, the reset member 24 may also be a torsion spring, a leaf spring or an elastic band structure, and its specific configuration may be adjusted according to actual conditions and is not limited in this embodiment.

[0207] Optionally, see Figure 10 In this embodiment, the second carrier module 2 may further include a sleeve 25. The sleeve 25 is connected to the second carrier 21. When the second tank 202 is placed on the second carrier 21, the second tank 202 is inverted in the sleeve 25. In this way, the sleeve 25 can be used to limit and protect the second tank 202, preventing it from tipping over, thereby improving the stability of the packaging operation.

[0208] like Figure 5 As shown, during subpackaging, liquid will flow along the top surface of the first carrier 11. When a gap exists between the sidewalls of the first carrier 11 and the sidewalls of the receiving groove 211, the liquid on the top surface of the first carrier 11 will flow out through the gap, causing leakage. This is particularly true when the liquid to be subpacked is easily vaporized, such as liquid Freon, liquid nitrogen, or liquid ammonia. These liquids easily vaporize during subpackaging and, in a vaporized state, are more likely to leak through the aforementioned gap. This not only results in waste but also has environmental impacts.

[0209] For these reasons, repackaging must be done in a sealed environment to prevent not only liquid leakage but also gas leakage from vaporized liquids. This is especially true for liquids that can pollute the environment. Providing a sealed environment during the repackaging process can also prevent contamination of the external environment.

[0210] See also Figure 9 and Figure 10In this embodiment, to improve sealing performance, the second carrier module 2 further includes a sealing structure 7. After the second opening member 23 opens the second tank opening, a sealed cavity is formed between the sealing structure 7 and the first carrier 11, thereby preventing a gap from forming between the sidewalls of the first carrier 11 and the sidewalls of the receiving groove 211. This prevents liquid on the top surface of the first carrier 11 from flowing out through the gap, or vaporized gas from flowing out of the gap, which could cause liquid leakage.

[0211] Optionally, the sealing structure 7 may be provided on the side wall of the receiving groove 211 of the second carrier 21 , thereby sealing the gap between the receiving groove 211 and the side wall of the first carrier 11 to form a sealed cavity.

[0212] like Figure 10 As shown, the sealing structure 7 may optionally include a first sealing member 71 and a second sealing member 72. The first sealing member 71 is used to form a sealed cavity when the first opening of the can is opened by the first opening member 22. The first sealing member 71 may be used to achieve sealing to prevent leakage during the subpackaging process.

[0213] like Figure 9 As shown, the second sealing member 72 is used to form a sealed cavity when the first opening member 22 leaves the first can opening. At this point, the subpackaging process is completed, but there is still residual liquid in the sealed cavity. To facilitate subsequent recycling, the second sealing member 72 can be used to achieve sealing. Optionally, the first sealing member 71 and the second sealing member 72 are arranged at intervals on the inner wall of the receiving groove 211. The first sealing member 71 is above the second sealing member 72, that is, the first sealing member 71 is closer to the bottom surface of the receiving groove 211. When the second carrier 21 approaches the first carrier 11 along the first direction, the first carrier 11 will first pass through the second sealing member 72. At this time, a first layer of sealing will be formed between the first carrier 11 and the receiving groove 211. When the second carrier 21 continues to approach the first carrier 11, the first carrier 11 will pass through the first sealing member 71. At this time, a second layer of sealing will be formed between the first carrier 11 and the receiving groove 211.

[0214] like Figure 5 As shown, when the first opening member 22 opens the first can opening, dispensing begins. At this point, the first sealing member 71 is located between the sidewall of the first carrier 11 and the sidewall of the receiving groove 211 to seal the gap between the sidewalls of the first carrier 11 and the sidewall of the receiving groove 211, thereby preventing liquid from leaking through the gap during dispensing.

[0215] like Figure 9As shown, after the subpackaging is complete, the second carrier 21 gradually moves away from the first carrier 11. To facilitate recycling, the second carrier 21 stops moving when the first end 2121 of the recycling channel 212 is connected to the sealed cavity. At this time, the second sealing member 72 is located between the sidewall of the first carrier 11 and the sidewall of the receiving groove 211, sealing the gap between the sidewalls of the first carrier 11 and the receiving groove 211, thereby preventing liquid leakage from this gap during recycling.

[0216] It is worth noting that by providing the first sealing member 71 and the second sealing member 72, the first carrier 11 can be sealed at different positions within the receiving groove 211. This allows for sealing in different packaging states to prevent liquid leakage, thereby reducing waste and avoiding environmental pollution. It is understood that the first sealing member 71 and the second sealing member 72 can be sealing rubber rings, sealing silicone rings, or sealing gaskets, and the selection can be based on actual conditions and is not limited in this embodiment.

[0217] Please combine Figure 2 and Figure 10 In some embodiments, since the second carrier module 2 needs to move along the first direction and the second direction relative to the first carrier module 1, in order to facilitate driving the second carrier module 2, the packaging device 100 can also include a first driving module 8. The first driving module 8 is introduced below.

[0218] The first driving module 8 is connected to the second carrier module 2. The first driving module 8 is used to drive the second carrier module 2 to move in a first direction close to the first carrier module 1, and to move in a second direction away from the first carrier module 1, thereby driving the second carrier module 2.

[0219] like Figure 2 As shown, optionally, the first driving module 8 may include a driving source 81. The driving source 81 is connected to the second supporting module 2, and the driving source 81 can move along the first direction and / or the second direction, thereby driving the second supporting module 2 to move.

[0220] In one implementation, the driving source 81 may be a structure such as an electric motor, a telescopic electric cylinder, a lead screw structure, etc. that can autonomously move in a certain direction to realize automatic driving of the second carrying module 2 .

[0221] In another implementation, the driving source 81 may be driven by an operator, that is, the second carrying module 2 is moved manually.

[0222] Optionally, when the second tank 202 is disposed on the second support 21, the driving source 81 may act directly on the second tank 202, so as to transmit power to the second support 21 through the second tank 202. Alternatively, the driving source 81 may act directly on the second support 21, thereby driving the second support 21 and the second tank 202 to move.

[0223] like Figure 10 As shown, optionally, the first driving module 8 may further include a reset component 82. The reset component 82 is connected to the second supporting module 2 and is adapted to reset the second supporting module 2 so that the second supporting module 2 moves away from the first supporting module 1 along the second direction when the driving force of the driving source 81 is lost.

[0224] like Figure 10 As shown, optionally, the reset assembly 82 may include a first plate 821 and an elastic member 822. The first plate 821 is connected to the second bearing member 21, one end of the elastic member 822 is connected to the first plate 821, and the other end 1 of the elastic member 822 is connected to a fixed structure, such as a fixed frame or the ground.

[0225] The direction of the fixing structure relative to the first plate 821 is the first direction, or in other words, the fixing structure is located below the first plate 821. When the first plate 821 moves in the first direction under the action of an external force, the elastic member 822 is compressed, generating an elastic force. If the first plate 821 loses external control, the first plate 821 moves in the second direction under the elastic force of the elastic member 822.

[0226] The reset process of the reset component 82 is described below:

[0227] When the driving source 81 drives the second carrier 21 to move in the first direction, the second carrier 21 will drive the first plate 821 to move together. At this time, the first plate 821 moves in the first direction, so that the elastic member 822 is compressed, thereby generating an elastic force to restore the deformation. When the driving source 81 moves away from the second carrier 21, under the action of the elastic force of the elastic member 822, the first plate 821 will be driven to move in the second direction, thereby driving the second carrier 21 to move in the second direction, realizing the automatic reset of the second carrier 21. It can be understood that the above-mentioned elastic member 822 can be a columnar spring, or a leaf spring. In this embodiment, the specific structure of the elastic member 822 is not limited.

[0228] It is worth noting that when the driving source 81 can realize the movement of the second bearing member 21 in the first direction and the second direction, the reset assembly 82 may not be provided. That is, the driving source 81 can be used to realize the reset without the need for additional structures.

[0229] Alternatively, as Figure 10 As shown, the first driving module 8 may further include a fixing assembly 83. The fixing assembly 83 is connected to a fixed structure, such as a fixed frame or the ground, so as to support the fixing assembly 83 using the fixed structure.

[0230] The fixing assembly 83 is further used to connect the elastic member 822 , that is, the elastic member 822 is located between the first plate 821 and the fixing assembly 83 , so that the fixing assembly 83 can support the elastic member 822 .

[0231] In one implementation, Figure 10 As shown, the fixing assembly 83 may include a first fixing plate 831 and a second fixing plate 832 that are spaced apart. The direction in which the first fixing plate 831 points to the second fixing plate 832 is the first direction. The second fixing plate 832 is arranged on the fixing structure, and the first fixing plate 831 is fixedly connected to the second fixing plate 832. The first plate body 821 and the elastic member 822 are located between the first fixing plate 831 and the second fixing plate 832, and the elastic member 822 is connected to the second fixing plate 832. The restriction of the first fixing plate 831 and the second fixing plate 832 can limit the range of motion of the first plate body 821 and the elastic member 822. In this way, it can be prevented that when the first plate body 821 moves in the second direction, the range of motion is too large, which affects the connection between the elastic member 822 and the second fixing plate 832.

[0232] In another implementation, the fixing assembly 83 may also have only one fixing plate, which is connected to a fixed structure, such as a fixed frame or the ground. The elastic member 822 is connected to the fixing plate to support the elastic member 822 using the fixing plate.

[0233] like Figure 10 As shown, optionally, the first driving module 8 may further include a guide assembly 84, which is connected to the first fixing plate 831, the second fixing plate 832 and the first plate body 821. The guide assembly 84 is used to guide the movement of the second bearing member 21.

[0234] Optionally, since the reset assembly 82 is connected to the guide assembly 84, the guide assembly 84 can be symmetrically arranged to facilitate force balance during the movement of the reset assembly 82. This can improve the smoothness of the movement of the reset assembly 82, thereby reducing damage to the fixing assembly 83, the guide assembly 84, and the second supporting member 21 due to force imbalance during movement, especially the guide assembly 84 itself, thereby improving the structural stability of the first driving module 8.

[0235] like Figure 10As shown, in one implementation, the guide assembly 84 may include a guide post 841 and a guide sleeve 842. The guide post 841 is fixedly connected between the first fixing plate 831 and the second fixing plate 832. The guide sleeve 842 is sleeved on the guide post 841 and connected to the second support member 21. In this way, the second support member 21 can move under the guidance of the guide post 841 via the guide sleeve 842.

[0236] Optionally, since the guide post 841 is fixed and the guide sleeve 842 and the guide post 841 can slide relative to each other, a bearing can be provided between the guide post 841 and the guide sleeve 842 to achieve lubrication.

[0237] In another embodiment, the guide assembly 84 may include a guide seat and a guide rail. The guide rail is fixedly connected between the first fixing plate 831 and the second fixing plate 832. The guide seat is disposed on the guide rail and connected to the second support member 21. In this way, the second support member 21 can move under the guidance of the guide rail via the guide seat.

[0238] See also Figure 11 In this embodiment, the packaging device 100 may further include a sealing assembly 9. The sealing assembly 9 is disposed at the contact position between the second tank opening and the second carrier 21 to achieve a sealed connection between the second tank body 202 and the second carrier 21. This prevents leakage of liquid in the second tank body 202 between the second tank body 202 and the second carrier 21.

[0239] like Figure 11 As shown, when the second tank body 202 is placed on the second carrier 21 , a gap may exist between the second tank opening and the second carrier 21 , causing the liquid in the second tank body 202 to flow out of the gap, thereby causing leakage.

[0240] like Figure 11 As shown, to address the aforementioned issues, the sealing assembly 9 may optionally include a first sealing ring 91. In this case, a first groove 215 is provided on the second carrier 21, and the first sealing ring 91 is disposed within the first groove 215. The first groove 215 is an annular groove and is positioned opposite the second tank opening. When the second tank body 202 is mounted on the second carrier 21, the second tank opening is connected to the first sealing ring 91, thereby sealing the gap between the second tank opening and the second carrier 21.

[0241] like Figure 11As shown, in one implementation, if a protective structure is provided around the outer edge of the second can body 202's opening, this protective structure may protrude beyond the edge of the opening. Therefore, to facilitate the proper fit between the second can opening and the first sealing ring 91, the sealing assembly 9 may further include a second sealing ring 92. The second carrier 21 also includes a second annular groove 216, corresponding to the protective structure of the second can body 202. This allows the second sealing ring 92 to fit snugly with the protective structure, ensuring a tight fit between the first sealing ring 91 and the second can opening.

[0242] Optionally, the depth of the second groove 216 is greater than the depth of the first groove 215. In this case, the thickness of the second sealing ring 92 is greater than the thickness of the first sealing ring 91. Since the protective structure is provided protruding from the second tank opening, the second sealing ring 92 needs to produce a larger deformation when achieving a tight fit between the second tank opening and the first sealing ring 91. Therefore, a thicker sealing ring can be selected to achieve sealing.

[0243] In another implementation, if the second tank body 202 does not have the aforementioned protective structure, only the aforementioned first sealing ring 91 may be provided to seal the tank opening. Alternatively, the sealing assembly 9 may be adaptively adjusted according to the shape of the tank opening of the second tank body 202, which is not limited in this embodiment.

[0244] like Figure 11 As shown, optionally, the sealing assembly 9 may further include a third sealing ring 93, which is fixedly connected to the second carrier 21. The third sealing ring 93 is pressed against the first sealing ring 91 and the second sealing ring 92, thereby preventing the first sealing ring 91 and the second sealing ring 92 from being separated from the first groove 215 and the second groove 216, thereby facilitating the installation and removal of the second tank body 202 and improving the packaging efficiency.

[0245] It is worth noting that the first sealing ring 91, the second sealing ring 92 and the third sealing ring 93 can be elastic gaskets such as silicone gaskets and rubber gaskets that can achieve liquid sealing, and are not limited in this embodiment. The following will introduce the packaging equipment 100 in conjunction with the specific packaging process:

[0246] Install the first tank body 201 and the second tank body 202 and realize alignment:

[0247] First, the first tank 201 and second tank 202 need to be installed in the first carrier module 1 and second carrier module 2, respectively. Specifically, multiple first tanks 201 are installed in the respective cavities 111 of the first carrier 11, and the second tank 202 is installed in the second carrier 21 via the sleeve 25. Once installation is complete, the second drive module 3 is used to move the first carrier module 1 and first tank 201 to the subassembly station and align them with the second carrier module 2 in preparation for subassembly.

[0248] Provide suitable temperature conditions:

[0249] The first driving module 8 is used to drive the second carrier 21 and the second tank body 202 to move closer to the first carrier 11. When the second opening member 23 contacts the first carrier 11, the temperature regulating module 4 is turned on to cool the first carrier 11 to provide a low-temperature environment for liquid packaging. When the temperature detection module 5 detects that the temperature of the first carrier 11 meets the requirements, the first driving module 8 can be further used to drive the second carrier 21 to continue to move closer to the first carrier 11. At this time, the second opening member 23 first contacts the first carrier 11. Supported by the first carrier 11, the second opening member 23 moves relative to the second carrier 21 until the second tank mouth is opened.

[0250] Start packaging:

[0251] The liquid in the second tank body 202 flows out through the through hole 231 of the second opening member 23 and flows to the converging portion 121. The diverter channel 122 diverts the liquid in the converging portion 121 so that the liquid flows to each first tank body 201 through each diverter channel 122. At this time, the first drive module 8 continues to drive the second carrier 21 toward the first carrier 11. The first opening member 22 gradually approaches and contacts the valve of the first tank body 201, and opens the first tank opening. In this way, the liquid in the diverter channel 122 can flow smoothly to the first tank opening directly or through the inter-tank channel 124 to achieve the filling of the first tank body 201.

[0252] Furthermore, the first drive module 8 needs to remain at the position where the first opening member 22 opens the first tank opening for a period of time to allow the first tank body 201 to be filled. When the first tank body 201 is full, the drive source 81 of the first drive module 8 moves away from the first carrier 11. The first carrier 11 is reset by the reset assembly 82, allowing the first opening member 22 to move away from the valve of the first tank opening, thereby automatically closing the valve and preventing liquid leakage from the first tank body 201.

[0253] Carry out recycling work:

[0254] In the process that the second carrier 21 gradually moves away from the first carrier 11, the second carrier 21 moves to a certain position, such as Figure 9 When the second support member 21 is in the position shown, the driving source 81 of the first driving module 8 controls the second support member 21 to stay at the position, so that the first end 2121 of the recovery channel 212 is connected to the sealed cavity.

[0255] At this time, the temperature regulating module 4 is controlled to heat so that the liquid remaining in the sealed cavity is vaporized and recovered to the recovery component through the recovery channel 212 to achieve recovery, thereby protecting the packaging environment.

[0256] After the recycling is complete, the second carrier 21 can continue to move away from the first carrier 11. When the first carrier 11 completely leaves the receiving groove 211 of the second carrier 21, the second driving module 3 can drive the first carrier 11 to move in a direction perpendicular to the first direction, thereby moving away from the subpackaging station to facilitate the removal of the first can 201. At this point, the subpackaging process is complete.

[0257] It is worth noting that when the liquid to be packaged does not require temperature restrictions, the above-mentioned temperature adjustment operation and related structures can be omitted.

[0258] The subpackaging device 100 provided in this embodiment can not only realize the subpackaging of the liquid in the large-capacity tank body into the small-capacity tank body, but also can realize the filling of multiple small tank bodies in one subpackaging process, which can effectively improve the subpackaging efficiency. At the same time, for liquids that are easy to vaporize, the gradual opening of the second tank body 202 and the first tank body 201, and the provision of a low-temperature environment can effectively avoid the gasification of the liquid and leakage. In a low-temperature environment, the subpackaging process is still the subpackaging of the liquid, compared to the subpackaging process of the gas. The subpackaging process of the liquid can flow under the action of the liquid's own gravity, and does not require a vacuum or negative pressure environment, thereby effectively simplifying the structure of the subpackaging device 100. In this way, the use of pneumatic equipment can also be avoided, effectively reducing working noise. At the same time, for liquids that are easy to vaporize, the temperature regulating module 4 can also be used to gasify and recover them, which can improve the recovery rate of the liquid, reduce the impact on the subpackaging environment, and save energy.

[0259] In addition, the above operations of the packaging device 100 provided in this embodiment can be completed by the main control system during the packaging process, which facilitates the realization of automated control, can effectively improve the packaging efficiency, and reduce the workload of the operator. At the same time, the use of the main control system for control can achieve higher packaging accuracy and more uniform packaging of each first tank 201.

[0260] Second embodiment

[0261] During the liquid packaging process, some liquids, such as Freon (liquid refrigerant), liquid ammonia, and liquid nitrogen, require certain conditions to remain in a liquid state. These liquids are often packaged under negative pressure or vacuum to avoid leakage due to vaporization and inability to complete packaging.

[0262] However, pneumatic equipment is noisy and requires maintaining a certain pressure during the packaging process, resulting in a dangerous packaging environment and high operational requirements for operators. Furthermore, pneumatic equipment often requires a large number of pipes to connect, and the more pipes there are, the greater the risk of leakage during the packaging process.

[0263] Figure 12 It is a schematic diagram of the three-dimensional structure of the packaging equipment 100 provided in the second embodiment.

[0264] Figure 13 It is a schematic cross-sectional structural diagram of the packaging device 100 provided in the second embodiment.

[0265] See also Figure 12 and Figure 13 In order to facilitate the subpackaging of liquids that are easily vaporized, this embodiment further provides a subpackaging device 100, which includes a first carrier module 1, a second carrier module 2, and a temperature adjustment module 4. The first carrier module 1 is used to carry the first tank body 201, and the second carrier module 2 is used to carry the second tank body 202. The capacity of the second tank body 202 is larger than that of the first tank body 201, and the second carrier module 2 can move relative to the first carrier module 1. The temperature adjustment module 4 is arranged on the periphery of the first carrier module 1 and / or the second carrier module 2. When the second carrier module 2 moves to the first position relative to the first carrier module 1, the first carrier module 1 and the second carrier module 2 are sealed. This embodiment adjusts the temperature of the first carrier module 1 or the second carrier module 2 by providing the temperature adjustment module 4, so that the temperature in the sealed cavity formed between the first carrier module 1 and the second carrier module 2 can meet the conditions for maintaining the liquid in a liquid state during subpackaging, thereby achieving subpackaging in a liquid state, avoiding leakage of the liquid after vaporization, and preventing the first tank body 201 from being filled.

[0266] It is understandable that the first position may be the position where the second tank opening is opened, or may be the position before the second tank opening is opened, thereby preventing leakage after the liquid flows out when the second tank opening is opened.

[0267] Optionally, the temperature regulating module 4 can be set on the periphery of the first carrier module 1, or on the periphery of the second carrier module 2, or can be set on the peripheries of the first carrier module 1 and the second carrier module 2 at the same time. It can be adjusted according to actual conditions and is not limited in this embodiment.

[0268] Optionally, when the first carrier module 1 is sealed to the second carrier module 2 , a sealed cavity is formed between the first carrier module 1 and the second carrier module 2 , and at least one of the first tank body 201 and the second tank body 202 is located in the sealed cavity.

[0269] In one implementation, the first tank body 201 is located in a sealed cavity, and the second tank body 202 is not in the sealed cavity. However, since the second tank mouth of the second tank body 202 is connected to the sealed cavity, when the liquid in the second tank body 202 flows into the sealed cavity, the temperature of the sealed cavity is relatively low and the liquid will not vaporize, thereby realizing liquid packaging.

[0270] In another implementation, second tank 202 is located within a sealed cavity. The first opening of first tank 201 is connected to the sealed cavity. However, due to the relatively low temperature within the sealed cavity, the liquid does not vaporize, allowing the low-temperature liquid to flow smoothly into the first opening, thereby enabling liquid dispensing. Furthermore, when the second opening of second tank 202 is opened, the liquid does not vaporize, and thus the air pressure does not significantly change. This minimizes the impact on the sealed cavity's sealing structure, facilitating sealing.

[0271] In another implementation, the first tank body 201 and the second tank body 202 are both in the sealed cavity. The effect of the arrangement can be referred to the above description and will not be repeated here.

[0272] In this embodiment, taking the example that the first tank body 201 is in the sealed cavity and the second tank body 202 is not in the sealed cavity, the relevant structural settings of the temperature adjustment module 4, the first supporting module 1 and the second supporting module 2 of the packaging equipment 100 can refer to the introduction of the first embodiment and will not be repeated here.
