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

[0019] Example 1

[0020] See also Figures 1-2In an embodiment of the present invention, a capping device for a reagent bottle includes a three-claw cylinder 1, a plurality of guide rails 3 are provided on the circumference of the upper end of the three-claw cylinder 1, a plurality of first L-shaped connecting plates 2 sliding along the guide rails 3 are installed on the guide rails 3, a second L-shaped connecting plate 4 is installed on the first L-shaped connecting plate 2, the first L-shaped connecting plate 2 and the second L-shaped connecting plate 4 are enclosed to form an installation cavity 5, the first L-shaped connecting plate 2 and the second L-shaped connecting plate 4 are symmetrically arranged, a motor 8 is installed at the lower end of the second L-shaped connecting plate 4, a rotating shaft 6 is installed at the upper end of the motor 8, a reducer 9 is installed at the lower end of the motor 8, a rubber block 7 is installed on the rotating shaft 6, the guide rail 3 is arranged parallel to the three-claw cylinder 1, and the rubber block 7 is arranged parallel to the guide rail 3. The three-claw cylinder 1 drives the first L-shaped connecting plate 2 to slide along the guide rail 3. Three guide rails 3 are arranged radially along the upper center of the three-claw cylinder 1. The first L-shaped connecting plate 2 moves toward the upper center of the three-claw cylinder 1 to realize the rubber block 7 to lock the bottle cap. The motor drives the rotating shaft 6 to rotate, driving the rubber block 7 to screw the bottle cap off.

[0021] In this embodiment, the rubber block 7 is a truncated cone structure, which is more conducive to the screwing operation of the bottle cap, thereby improving the efficiency of screwing.

[0022] In this embodiment, the thickness of the rubber block 7 is m, 10 mm ≤ m ≤ 20 mm. Specifically in this embodiment, m is 15 mm.

[0023] In this embodiment, the diameter of the upper end surface of the rubber block 7 is d1, and the diameter of the lower end surface of the rubber block 7 is d2, 30mm≤d1<d2≤60mm. Specifically in this embodiment, d1 is 30mm, and d2 is 40mm.

[0024] Example 2

[0025] like Figure 3-4 As shown, the difference between this embodiment and embodiment 1 is that it also includes a lock core 10 installed on the rotating shaft 6, the inner wall of the lock core 10 is provided with a plurality of arc edges 12, and a plug hole 11 is provided in the lock core 10. It can be understood that after the lock core 10 is installed on the rotating shaft 6, when the three-claw cylinder 1 is not working, the motor 8 directly drives the rotating shaft 6 to drive the lock core 10 to rotate to realize the capping operation of the bottle cap, which effectively improves the efficiency of the capping.

[0026] Example 3

[0027] like Figure 5 As shown, the difference between this embodiment and embodiment 2 is that a spring 13 is arranged in the insertion hole 11. When the capping mechanism is lifted, the bottle cap is ejected by the spring 13, thereby solving the problem that the plastic cover of the bottle cap is stuck in the rubber lock core.

[0028] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
