DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0024] Referring to Figures 1-5The application discloses a precise positioning sodium lactate filling device, which comprises a base 1, a rotating ring 3, a support frame 4, a gas cylinder 5 and a filling cylinder 6. The base 1 is provided with a rotating groove 2, and the rotating groove 2 is provided with a rotating motor 7. The rotating motor 7 is connected with the rotating ring 3 through a rotating mechanism. The rotating mechanism comprises a rotating gear 8 which is installed on the output shaft of the rotating motor 7. The rotating ring 3 is provided with a circular gear ring 10 which is engaged with the rotating gear 8. As shown in the drawings, the rotating ring 3 is further provided with an engagement groove 9. The engagement groove 9 is arranged to provide a place for the rotating motor 7. The circular gear ring 10 is arranged on the inner wall of the engagement groove 9.

[0025] As shown in the drawings, the vertical section view of the rotating groove 2 is in the shape of an inverted T, which can realize the vertical positioning of the rotating ring 3, so that the rotating ring 3 can only rotate in the rotating groove 2 and cannot be separated from the rotating groove 2.

[0026] The upper end surface of the rotating ring 3 is provided with a placing groove 11. The inner bottom wall of the placing groove 11 is provided with a rotating groove 13. The rotating ring 3 is internally provided with a transmission chamber 12. The rotating groove 13 is internally provided with a screw rod 17 which extends into the transmission chamber 12. The transmission chamber 12 is fixedly provided with a vertical rod 14. The vertical rod 14 is rotatably provided with a middle gear 16 through a reset mechanism. The reset mechanism comprises a torsion spring 15 which is sleeved on the outer portion of the vertical rod 14. The two ends of the torsion spring 15 are respectively connected with the inner wall of the transmission chamber 12 and the outer wall of the middle gear 16. The elastic potential energy provided by the above-mentioned torsion spring 15 can keep the screw rod 17 and other components in a stable state without external intervention, that is, the positions of the four positioning frames 19 in each placing groove 11 are stable and are in a separated and dispersed state.

[0027] As shown in the drawings, the positioning frame 19 is composed of a rectangular rod and a circular wheel. The circular wheel and the rectangular rod are rotatably connected. The outer wall of the circular wheel is further provided with a protective pad made of rubber.

[0028] The screw rod 17 is connected with the middle gear 16 through a rotating mechanism. The rotating mechanism comprises a side gear 18 which is installed on the screw rod 17. The side gear 18 is engaged with the middle gear 16. The screw rod 17 is threadedly sleeved with the positioning frame 19. The inner wall of the rotating groove 2 is provided with a transmission groove 21. The transmission groove 21 is internally provided with a conical rack 23. The screw rod 17 is connected with the conical rack 23 through a transmission mechanism. The transmission mechanism comprises a transmission gear 22 which is installed on the screw rod 17. The transmission gear 22 is correspondingly arranged with the conical rack 23. As shown in the drawings, each placing groove 11 corresponds to four screw rods 17. One of the four screw rods 17 extends into the transmission groove 21. After the transmission gear 22 on the screw rod 17 and the conical rack 23 are engaged with each other, the screw rod 17 can be rotated along with the rotating ring 3. The screw rod 17 is matched with the middle gear 16 and the side gear 18, so that the other three screw rods 17 can be rotated, thereby moving the four positioning frames 19 in the placing groove 11 close to each other, and realizing the clamping and fixing operation of the container for packaging sodium lactate in the placing groove 11.

[0029] As shown in the figure, the container is also cylindrical, and the four positioning racks 19 are distributed at equal intervals in the circumferential direction, and the container is placed in the placing groove 11 at will and is finally adjusted to the central position in the placing groove 11 by the four positioning racks 19.

[0030] A limiting rod 20 is arranged in the rotating groove 13 and slides through the positioning rack 19. The limiting rod 20 realizes the limiting of the positioning rack 19 and can avoid the rotation of the positioning rack 19 along with the screw rod 17.

[0031] It should be noted that the thread direction of the four screw rods 17 corresponding to each placing groove 11 is designed according to the rotating direction, and as long as the four positioning racks 19 in each placing groove 11 can move close to or away from each other synchronously.

[0032] The teeth of the above-mentioned gear 16, side gear 18, transmission gear 22 and the surface of the conical rack 23 are drawn, and the threads on the surface of the screw rod 17 are not drawn (to avoid unclear drawings), which is only a simple structure diagram.

[0033] The components not specifically described in the utility model are standard components and can be purchased from the market, and the specific connection mode of each component adopts a mature means in the prior art, which will not be described in detail here, and the contents not described in detail in the specification belong to the prior art known to those skilled in the art.

[0034] In use, the container is placed in the placing groove 11, the rotating motor 7 is started to rotate the rotating ring 3 by relying on the rotating gear 8 and the circular gear ring 10, one of the placing grooves 11 moves and gradually approaches the filling cylinder 6, then the transmission gear 22 is engaged with the conical rack 23, then the rotating ring 3 continues to rotate and drives the placing groove 11 to be directly below the filling cylinder 6, in the process, one of the screw rods 17 is driven to rotate the gear 16 by the side gear 18 under the action of the conical rack 23, the gear 16 is matched with the other three side gears 18 to realize the rotation of the other three screw rods 17, the four screw rods 17 drive the four positioning racks 19 to move close, and finally realize the clamping and positioning operation of the container in the placing groove 11, and the container is kept in the central position in the placing groove 11, and finally the cylinder 5 is started to drive the filling cylinder 6 to descend for sodium lactate filling operation.

[0035] After filling, the filling cylinder 6 rises to reset, and the rotating ring 3 continues to rotate, at this time, the transmission gear 22 is disengaged from the conical rack 23 (the conical rack 23 has only one section), at this time, the gear 16 is reset under the action of the torsion spring 15, and therefore the four positioning racks 19 are reset to release the clamping and positioning of the container, which is convenient for taking out.

[0036] The above merely is the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited to this, any skilled person in the technical field according to the technical scheme and the utility model concept of the present utility model is equivalent to replace or change within the technical range disclosed by the present utility model, and should be covered in the protection scope of the present utility model.
