[0002] Glass bottles or plastic bottles for containing reagents can be classified in many ways according to color, shape and purpose. In the application process of reagent bottles, a sealing cap is needed to ensure the sealing inside the bottle. Among them, the "a kind of capping mechanism" disclosed by the application number "202222345105.3" is also an increasingly mature technology, including a rotating column, the outer periphery of which is connected to a pressing drive shell through a return member; a driving column is fixedly installed on the rotating column. The utility model proposes a capping mechanism, which presses the bottle cap by a rubber sleeve to drive the bottle cap to rotate, and cooperates with the bottle cap to move downward, so as to achieve the effect of rotating and moving the bottle cap downward, and reduce the phenomenon of damage to the bottle body. Although the patent reduces the phenomenon of damage to the bottle body, the size of the bottle mouth also changes due to the different sizes of the reagent bottles, and the size of the bottle cap connected to the bottle mouth also changes. When the bottle cap is too small, the pressing drive shell will not be able to press on the bottle cap, which will cause difficulty in use and reduce the applicability. In view of this, we provide a reagent bottle automatic capping mechanism to solve the above problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] See also Figure 1-4 The utility model provides the following technical solutions: an automatic screw capping mechanism for a reagent bottle, comprising a shell 1, a rotating shaft 2 is connected to the top of the shell 1, a mounting box 3 is arranged at the top of the shell 1, a motor 4 is installed inside the mounting box 3, a docking shaft 5 is installed at the top of the mounting box 3, a silicone pad 6 is installed on the inner wall of the cavity of the shell 1, a vacuum suction cup 7 is arranged in the cavity of the shell 1, a spring 8 is connected to the top of the vacuum suction cup 7, and a guide rod 11 is also installed at the top of the vacuum suction cup 7.

[0021] Preferably, the top end of the rotating shaft 2 is connected to the output shaft of the motor 4 through a coupling, and the housing 1 forms a rotating connection between the rotating shaft 2 and the motor 4 .

[0022] When in use, the working output shaft of the motor 4 drives the rotating shaft 2 and the housing 1 connected at the bottom end to rotate, thereby tightening the bottle cap and the reagent bottle for assembly.

[0023] Preferably, the guide rod 11 is installed at the central axis of the vacuum suction cup 7 , and five springs 8 are arranged in a circle, and the other end of the spring 8 is connected to the top of the cavity of the shell 1 .

[0024] During specific use, the vacuum suction cup 7 is allowed to move stably in the cavity of the housing 1 through the guide rod 11 to avoid the vacuum suction cup 7 moving up and down with uneven force and thus the spring 8 being bent.

[0025] Preferably, the silicone pad 6 is made of food-grade silicone material, and the vacuum suction cup 7 is elastically connected to the housing 1 through the spring 8.

[0026] During specific use, the vacuum suction cup 7 has a certain range of movement due to the elasticity of the spring 8, so as to avoid the shell 1 driving the bottle cap to be squeezed when assembling with the reagent bottle, thereby preventing the reagent bottle from being damaged.

[0027] Preferably, a mounting groove 12 is provided inside the housing 1 , an air pump 9 is installed inside the mounting groove 12 , and a vacuum tube 10 is connected to the output end of the air pump 9 .

[0028] When in use, the vacuum suction cup 7 generates suction by starting the air pump 9, thereby adsorbing the bottle cap and the reagent bottle for assembly.

[0029] Preferably, the other end of the vacuum tube 10 is connected to the vacuum suction cup 7, and the vacuum tube 10 is a bellows.

[0030] During specific use, when the vacuum suction cup 7 is moved by the spring 8 , the vacuum tube 10 contracts to avoid restricting the movement of the vacuum suction cup 7 .

[0031] In the embodiment, when assembling the reagent bottle and the bottle cap, first, take out the bottle cap and place it in the cavity of the shell 1, then the air pump 9 works to generate suction and transmit it to the vacuum suction cup 7, and then the vacuum suction cup 7 adsorbs the bottle cap, and then drives the bottle cap close to the bottle mouth of the reagent bottle, and then fixes the docking shaft 5 to start the motor 4, wherein the model of the motor 4 is ZWMD012012, and then the output shaft of the motor 4 drives the rotating shaft 2 to rotate, and at the same time the rotating shaft 2 will drive the shell 1 to rotate, and then the bottle cap descends along the bottle mouth thread of the reagent bottle, thereby completing the assembly of the bottle cap and the reagent bottle.

[0032] It should be noted that: when the bottle cap descends along the bottle mouth thread of the reagent bottle, the bottle cap will drive the vacuum suction cup 7 to descend, and the vacuum suction cup 7 will drive the spring 8 to extend, and the guide rod 11 will also descend. After the assembly of the bottle cap and the reagent bottle is completed, the air pump 9 stops working, allowing the vacuum suction cup 7 to rebound to its initial position in the cavity of the shell 1 through the elasticity of the spring 8.

[0033] In another embodiment, if the assembly of the bottle cap and the reagent bottle adopts a downward pressing method, the bottle cap is also taken out and placed in the cavity of the shell 1, and then the air pump 9 works to generate suction and transmit it to the vacuum suction cup 7, and then the vacuum suction cup 7 adsorbs the bottle cap, and then the docking shaft 5 is controlled to descend. At this time, the vacuum suction cup 7 is squeezed to drive the spring 8 to contract, and the guide rod 11 also rises until the downward squeezing force completes the assembly of the bottle cap and the reagent bottle, and the air pump 9 stops working, allowing the vacuum suction cup 7 to rebound to the initial position in the cavity of the shell 1 through the elasticity of the spring 8.

[0034] It should be supplemented that the size of the vacuum suction cup 7 is compatible with the size of the cavity of the shell 1, so that bottle caps of different sizes can be sucked by the vacuum suction cup 7 and then assembled with the reagent bottle, thereby improving applicability.

[0035] In summary, according to the description of the embodiment, the automatic capping mechanism for reagent bottles not only improves the convenience of use, but also improves the applicability. Subsequently, the assembly of two types of bottle caps with reagent bottles is also taken into account, thereby improving the practicality of the automatic capping mechanism for reagent bottles.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
