[0040] Drive assembly 20 can adopt any feasible drive structure in the art, for example, drive assembly 20 can be electric drive structure, can also be gas drive structure or hydraulic drive structure etc., and specific does not do limit.

[0041] Drive assembly 20 can drive heat exchange component 30 to move along the first direction Z. Drive assembly 20 and heat exchange component 30 can be directly connected, can also be indirectly connected, and specific does not do limit. Optionally, the first direction Z is the height direction of container sealing device 100, and the opening of container 300 is along the first direction Z and towards heat exchange component 30;Or, the first direction Z can also be the width direction or length direction of container sealing device 100, and the opening of container 300 is still along the first direction Z and towards heat exchange component 30, and specific does not do limit. The following is explained and described with the first direction Z as the height direction of container sealing device 100 as an example.

[0042] Sealing assembly 40 is connected with heat exchange component 30, and sealing assembly 40 is used to press and seal the opening of container 300 in the first direction Z, and heat exchange component 30 is used to heat exchange for sealing assembly 40.

[0043] Heat exchange component 30 and sealing assembly 40 can be directly connected, can also be indirectly connected, and specific does not do limit. Optionally, sealing assembly 40 can also move relative to heat exchange component 30 in the first direction Z;Or, sealing assembly 40 moves synchronously with heat exchange component 30 in the first direction Z.

In another example, when low-temperature stirring of the reactants in the containers 300 is required during the experiment, in order to avoid splashing of the reactants, the sealing assembly 40 and the heat exchange assembly 30 are driven by the driving assembly 20 to contact and press against the openings of the containers 300 to seal the containers 300. If part of the reactants splashes onto the sealing assembly 40 and condenses due to the low temperature, the heat exchange assembly 30 is used to heat the sealing assembly 40, so that the splashed reactants in the containers 300 flow back into the containers 300 after colliding with the sealing assembly 40 which has a higher temperature, thereby avoiding a decrease in the reactants in the containers 300.

[0046] The container sealing device 100 in the embodiment of the utility model, through setting heat exchange assembly 30 and sealing assembly 40, driving assembly 20 drives heat exchange assembly 30 to move in the first direction Z, and then drives sealing assembly 40 to move to seal the opening of container 300, and heat exchange assembly 30 can heat sealing assembly 40, avoid the reactant in container 300 to reduce due to temperature change, sealing effect is good, sealing efficiency is high, and need not manual operation, and the degree of automation is high.

[0047] In an example, please refer to Figures 1 to 3 The sealing assembly 40 includes a first surface 411 and a second surface 412 opposite to each other, and a side surface 413 connecting the first surface 411 and the second surface 412, the first surface 411 is used to contact the opening of the container 300, and the heat exchange assembly 30 is arranged on the second surface 412 and / or the side surface 413.

[0048] Optionally, the first surface 411 and the second surface 412 are oppositely arranged in the first direction Z. The shapes and sizes of the first surface 411 and the second surface 412 are not limited, and the shapes and sizes of the first surface 411 and the second surface 412 can be the same or different. For example, the shapes of the first surface 411 and the second surface 412 can be rectangular, circular, trapezoidal, regular polygon, irregular figure, etc., or the shapes of the first surface 411 and the second surface 412 are different; the sizes of the first surface 411 and the second surface 412 are the same, or the area of the first surface 411 is smaller than the area of the second surface 412, which is not limited.

[0049] Optionally, the sealing assembly 40 is substantially a cuboid, the first surface 411 and the second surface 412 are substantially rectangular, and the side surface 413 can be a single side surface 413 connecting the first surface 411 and the second surface 412, or four side surfaces 413 connecting the first surface 411 and the second surface 412 and substantially in the shape of a "mouth"; or the sealing assembly 40 is substantially a cylinder, the first surface 411 and the second surface 412 are circular, and the side surface 413 is the side surface of the cylinder. Any of the above manners can be used, and the specific manner is not limited.

[0050] The connection manner between the heat exchange assembly 30 and the sealing assembly 40 can be bonding, clamping, screwing, riveting, magnetic attraction, etc., which is not limited. Optionally, the heat exchange assembly 30 is arranged on the second surface 412 or the side surface 413, or the second surface 412 and the side surface 413 are both provided with the heat exchange assembly 30 to sufficiently heat exchange the sealing assembly 40.

[0051] By arranging the first surface 411 of the sealing assembly 40 to abut against the opening of the container 300 and arranging the heat exchange assembly 30 on the second surface 412 and / or the side surface 413, the heat exchange assembly 30 can heat exchange the sealing assembly 40 while sealing the container 300, and the sealing manner is simple and efficient, and the arrangement position of the heat exchange assembly 30 can be selected according to actual product needs.

[0052] In one embodiment, please refer to Figure 3 The sealing assembly 40 includes an elastic member 42 and a sealing member 43, the sealing member 43 is connected with the elastic member 42 in the first direction Z, and the surface of the sealing member 43 facing away from the elastic member 42 is used to abut against and seal the container 300. At this time, the heat exchange assembly 30 can be arranged on the surface of the elastic member 42 facing away from the sealing member 43.

[0053] Optionally, the sealing member 43 and the elastic member 42 can be connected by bonding, clamping, screwing, etc., or the surface of the elastic member 42 facing the sealed container 300 is sprayed or coated with a material to form the sealing member 43, which is not limited.

[0054] The elastic member 42 is elastic and can be elastically deformed at least in the first direction Z. Optionally, the elastic member 42 can be made of silicone, rubber, sponge, polyurethane or other elastic plastic materials commonly used in the art. Optionally, the Shore hardness of the elastic member 42 is 20°-30°. In one specific embodiment, the elastic member 42 is a silicone plate with a Shore hardness of 20°-30°. Optionally, the thickness of the elastic member 42 can be 3mm-8mm, and can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc. without limitation. The sealing assembly 40 can simultaneously seal the openings of multiple containers 300, and at this time, the elastic deformation of the elastic member 42 can eliminate the influence of the height difference of the multiple containers 300 on the sealing consistency, thereby improving the sealing effect of the sealing assembly 40.

[0055] The sealing member 43 can be in the form of a film and is attached to the surface of the elastic member 42 in the first direction Z. Since the sealing member 43 can directly contact the splashed reactants or the rising gas flow in the container 300, the material of the sealing member 43 should have corrosion resistance, not react with the reactants in the container 300, avoid contaminating the reactants, and also prevent the reactants in the container 300 from contacting the elastic member 42 and causing corrosion to the elastic member 42. In addition, the sealing member 43 can also have the characteristics of high temperature resistance and low adhesion, and can be used in a high temperature environment without deformation due to high temperature, and will not lift the container 300 when the sealing member 43 is separated from the opening of the container 300, thereby improving the safety of the experiment. Optionally, the material of the sealing member 43 can be PFA (perfluoroalkoxy copolymer), PTFE film (polytetrafluoroethylene), etc. without limitation.

[0056] By providing the elastic member 42 and the sealing member 43, the elastic member 42 can be elastically deformed to eliminate the influence of the height difference between the containers 300, ensure the sealing consistency of different containers 300, and improve the sealing effect of the sealing assembly 40. The sealing member 43 abuts against the opening of the container 300 and does not react with the reactants in the container 300, thereby preventing the reactants in the container 300 from contacting the elastic member 42 and reacting, and ensuring the experimental effect.

[0057] In one embodiment, please refer to 1 to Figure 3 The sealing assembly 40 further comprises a support member 44 connected to the surface of the elastic member 42 away from the sealing member 43, and the heat exchange assembly 30 is arranged on the surface of the support member 44 away from the elastic member 42.

[0058] The support 44 is used to mount the elastic member 42 and the sealing member 43. The support 44 can be substantially plate-shaped, and the support 44 and the elastic member 42 can be connected by bonding, clamping, screwing, etc., without limitation. The support 44 can be made of a material with relatively large rigidity to support the elastic member 42 and the sealing member 43. The material of the support 44 can be aluminum, iron, alloys thereof, etc., without limitation. Alternatively, since the surface of the support 44 away from the elastic member 42 is connected with the heat exchange assembly 30, when the rigidity of the heat exchange assembly 30 is relatively large, the material of the support 44 can not be required, and the heat exchange assembly 30 can provide support for the sealing assembly 40, without limitation.

[0059] Optionally, the first surface 411 is a surface of the sealing member 43 away from the elastic member 42, and the second surface 412 is a surface of the support 44 away from the elastic member 42.

[0060] Optionally, the heat exchange assembly 30 and the support 44 can be connected by welding, bonding, clamping, screwing, riveting, etc. The heat exchange assembly 30 can be arranged on the surface of the support 44 away from the elastic member 42, or on the side surface of the support 44, without limitation.

[0061] By arranging the support 44, the support 44 can provide support for the elastic member 42 and the sealing member 43. During the process that the sealing member 43 contacts and is pressed by the opening of the container 300, the support 44 can reduce the deformation degree of the side of the elastic member 42 away from the sealing member 43, avoid excessive deformation of the elastic member 42, and ensure the sealing effect of the sealing assembly 40.

[0062] In an embodiment, as shown in Figure 3 In the orthographic projection along the first direction Z, the elastic member 42 is located in the support 44, and the sealing member 43 is located in the elastic member 42.

[0065] By limiting the size relationship of the supporting member 44, the elastic member 42 and the sealing member 43, the connection stability of the sealing assembly 40 is ensured, and the sealing effect is reliable.

[0066] In an embodiment, the sealing assembly 40 is detachably connected with the heat exchange assembly 30. Optionally, after the experimental operation of a group of containers 300 is completed, the surface of the sealing assembly 40 used for sealing the opening of the container 300 can be attached with the reactants in the container 300, at this time, the sealing assembly 40 and the heat exchange assembly 30 can be separated to replace or clean the sealing assembly 40, so as to avoid the pollution of the sealing assembly 40 to the reactants in the next group of containers 300.

[0070] By setting the detachable sealing assembly 40 and the heat exchange assembly 30, the sealing assembly 40 can be replaced simply and efficiently, and the pollution to the reactants in the container 300 is avoided.

[0071] In an embodiment, please refer to Figure 1 The sealing assembly 40 is further provided with an operating member 45, the operating member 45 is used to connect or separate the sealing assembly 40 and the heat exchange assembly 30, and the operating member 45 is located on one side of the sealing assembly 40 and has a spacing with the heat exchange assembly 30.

The operation member 45 can also be arranged on the side surface 413 of the sealing assembly 40, or the operation member 45 can be arranged at an angle with respect to the side surface 413 or the first surface 411 of the sealing assembly 40, and the specific angle is not limited. Optionally, the operation member 45 can be arranged on one side edge of the sealing assembly 40 and extend outward along the first direction Z and / or the second direction X to be as far away from the heat exchange assembly 30 as possible.

[0074] By arranging the operation member 45, when the sealing assembly 40 needs to be transported and disassembled, the operation member 45 can be grabbed by hand or a machine to operate the sealing assembly 40, which is convenient, and can also avoid pollution caused by direct contact between the first surface 411 and the hand or the machine.
