Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] Please see Figure 1-6 The present invention provides the following technical solution: an automatic cap screwing mechanism, comprising a column 1, a fixed base 2, a cylinder 3, a cap screwing assembly 4, and a control device 5. The fixed base 2 is provided on the column 1, and the cylinder 3 is fixedly installed on the fixed base 2. The top of the piston rod of the cylinder 3 is fixedly connected to a top plate 301, and the cap screwing assembly 4 is fixedly installed on the upper end of the top plate 301. The control device 5 is provided on one side of the column 1, and the control device 5 is connected to the cylinder 3 and the cap screwing assembly 4 for control.

[0025] Through the connection structure of the fixed base 2, cylinder 3 and capping assembly 4, the capping assembly 4 can be automatically raised and lowered under the action of cylinder 3. The capping assembly 4 can realize the automatic capping operation of the cryopreservation tube, providing a stable and clean production environment for the product, thereby improving production efficiency and yield.

[0026] The screw cap assembly 4 includes a mounting plate 401, a motor 402, a connecting rod 403, a connecting plate 404, a shaft seat 405, a rotating shaft 406, a coupling 407, a rotating cover 408, a spring 409, and a contoured silicone pad 4010. The motor 402 is fixedly mounted on the upper end of the mounting plate 401, and two connecting rods 403 are symmetrically fixedly connected to the lower end of the mounting plate 401. The lower ends of the two connecting rods 403 are fixedly connected to the connecting plate 404.

[0027] A bearing seat 405 is provided at the center of the connecting plate 404. A rotating shaft 406 is movably installed in the bearing seat 405. A coupling 407 is provided at the upper end of the rotating shaft 406. The upper end of the rotating shaft 406 is connected to the output shaft of the motor 402 through the coupling 407.

[0028] A fixing block is provided on the outer side of the rotating shaft 406 below the bearing seat 405, and a rectangular column 4061 is provided at the bottom of the rotating shaft 406.

[0029] A rotating cover 408 is movably provided at the lower end of the rotating shaft 406. A spring 409 is connected between the rotating cover 408 and the fixed block on the rotating shaft 406. A rectangular slot 4081 is provided inside the rotating cover 408.

[0030] The rectangular column 4061 at the bottom of the rotating shaft 406 is connected to the rectangular slot 4081 inside the rotating cover 408.

[0031] The bottom of the rotating cover 408 has a circular groove, and a contoured silicone pad 4010 is placed inside the circular groove.

[0033] The working principle and usage process of this utility model are as follows: In specific use, the cryopreservation tube is placed in the fixture, and the cap is placed on the bottle. The piston rod of the cylinder 3 drives the top plate 301 to descend into place, so that the conformal silicone pad 4010 presses the cap. As it moves down, the rotating cover 408 moves up along the rotating shaft 406, while the spring 409 is compressed, so that the conformal silicone pad 4010 keeps in contact with the cap. Then the motor 402 starts, and the output shaft rotates, driving the rotating shaft 406 to rotate. The rectangular column 4061 at the bottom of the rotating shaft 406 is connected to the rectangular slot 4081 opened inside the rotating cover 408, so that the rotating cover 408 rotates synchronously. The rotation of the rotating cover 408 drives the conformal silicone pad 4010 to rotate, thereby tightening the cap and achieving the purpose of automatic cap tightening, thus improving production efficiency.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
