[0024] Embodiment 1

[0025] Please refer to the attached Figure 1 and the attached Figure 2, this application provides an embodiment of a liquid filling and capping machine, including a device main body 1, a conveying mechanism 5, and a filling mechanism 3. The conveying mechanism 5 is arranged on the device main body 1, and is characterized in that: the capping machine further includes a capping mechanism 6, a capping mechanism 4, and a limiting mechanism 7. The capping mechanism 4 and the limiting mechanism 7 are both arranged on the conveying mechanism 5. The capping mechanism 6 is used to place the bottle cap on the bottle body, and the limiting mechanism 7 is used to adapt to bottle bodies of different diameters. The capping mechanism 4 includes a lifting rod 401, a connecting rod 402, and a capper 403. The lower end of the lifting rod 401 is connected to the conveying mechanism 5 through a fixing block 404. One end of the connecting rod 402 is fixedly connected to the upper end of the lifting rod 401, and the other end is rotatably connected to the upper end of the capper 403.

[0026] In specific implementation, the bottle first reaches the filling area. After the filling mechanism 3 fills the liquid, it reaches the capping area through the conveying mechanism 5. After the capping mechanism 6 caps it, it reaches the capping area, and the capper 403 performs the capping operation on it.

[0027] As a further improvement to the above embodiment, a rotating motor 405 is arranged inside one end of the connecting rod 402 that is rotatably connected to the capper 403. The output end of the rotating motor 405 is connected to the capper 403. The capper 403 includes a capper housing 4037, a telescopic motor 4031, a cone 4032, a connecting rod 4035, capping grippers 4033, and a spring 4034. The capper housing 4037 is fixedly connected to the output end of the rotating motor 405. The output end of the telescopic motor 4031 is connected to the cone 4032. The cone 4032 is slidably connected to the capping grippers 4033. The capping grippers 4033 are connected to each other in pairs by a spring 4034, and there is a fixing piece 4036 above the capping grippers for limiting.

[0028] In specific implementation, when the bottle reaches the capping area, the lifting rod 401 descends to drive the capper 403 to approach the bottle cap. At the same time, the output end of the telescopic motor 405 in the capper 403 moves upward, driving the cone 4032 to move upward to expand the coverage area of the capping grippers 4033. After the capping grippers 4033 reach the position of the bottle cap, the lifting rod 401 stops descending. At the same time, the output end of the telescopic motor 405 moves downward, driving the cone 4032 to move downward, and the capping grippers 4033 grasp the bottle cap. The capping grippers 4033 are connected to each other in pairs by a spring 4034, ensuring that the capping grippers 4033 will not loosen during capping. The capper housing 4037 is fixedly connected to the output end of the rotating motor 405. When the rotating motor 405 is powered on and operates, it drives the entire capper 403 to rotate, thereby realizing the tightening of the bottle cap.

[0029] Furthermore, the conveying mechanism 5 includes a conveyor belt 501 and a conveying base 502. The conveying base 502 is located above the device main body 1, and the conveyor belt 501 is located above the conveying base 502.

[0030] Further, the upper cover mechanism 6 includes an upper cover support 601, a push-pull cylinder 602, a stacking bin 603, and a push block 604. The upper cover support 601 is fixed above the conveying base 502 by screws. The stacking bin 603 is arranged on one side of the surface of the upper cover support 601, and bottle caps are placed in the stacking bin 603. The push-pull cylinder 602 is arranged on the other side of the surface of the upper cover support 601. The push block 604 is connected to the tail of the push-pull cylinder 602. When the bottle reaches the upper cover area, the push-pull cylinder 602 is activated to drive the push block 604 to push out the bottle cap.

[0031] Further, the limiting mechanism 7 includes a first fixing frame 713, a second fixing frame 714, a limiting column 712, a hand crank 715, a fixing plate 710, a limiting plate 711, a capping inductor 707, a capping clamping plate 708, and a capping limiting bracket 709. The first fixing frame 713 is fixed on both sides of the conveying base 502, and the second fixing frame is fixed on one side of the conveying base. Limiting through holes are provided on both the first fixing frame and the second fixing frame. The limiting column sequentially passes through the limiting through holes on the first fixing frame and the limiting plate 711 and is slidably connected to the limiting through holes and the limiting plate 711. The hand crank 715 passes through the limiting through hole on the second fixing frame and is threadedly connected to the limiting plate 711. The limiting plate 711 is provided with a capping limiting bracket 709 in the capping area. The capping inductor 707 is fixed on one side of the upper end of the capping limiting bracket 709, and a capping clamping plate 708 is provided in the middle.

[0032] In specific implementation, according to the diameter of the bottle body, rotate the hand crank 715 so that the limiting plate 711 moves linearly towards or away from the fixing plate 710 to adapt to the diameter of the bottle body, preventing the bottle from shaking during transportation. After the bottle reaches the capping area, the capping inductor 707 senses the bottle body, and the capping clamping plate 708 pops out through the motor to clamp the bottle body, and the capping device 403 completes the capping operation.

[0033] Further, the four end feet at the bottom of the device main body 1 are all fixed by fixing legs 2, which can play a role in supporting the device main body and preventing the device main body from getting damp. The lower surface of the fixing legs 2 is provided with rubber anti-slip pads, which can prevent the fixing legs 2 from slipping after work and causing the device to be unstable.

[0034] It should be noted that the components such as the rotating motor 405, the telescopic motor 4035, the push-pull cylinder 602, and the capping inductor 707 used in this application are all existing electronic components in the art. Those skilled in the art can obtain and understand the circuit structures of the rotating motor 405, the telescopic motor 4035, the push-pull cylinder 602, the capping inductor 707 and other electronic components and the circuit connection structures between them according to the existing public technical knowledge and technical materials. The embodiments of this application will not elaborate on this specifically, and those skilled in the art can freely select the corresponding models according to needs. This embodiment does not make specific limitations here.

[0035] The working principle of the present utility model is as follows:

[0036] Before the device works, according to the different diameters of the bottle body, it is necessary to adjust the position of the limit plate 711 to prevent the bottle body from shaking during the transportation and conveying process. When adjustment is required, rotate the hand rocker 715 and the hand rocker 715, so that the limit plate 711 moves linearly towards or away from the fixed plate 710 to adapt to the diameter of the bottle body, thereby enabling the device to limit the diameter of the bottle body and avoiding the occurrence of the bottle body tipping over during the transmission due to too much space. The bottle caps are placed in the stacking bin 603; start the motor of the conveyor belt 501, and the conveyor belt 501 starts to convey the bottles. After the bottles reach the filling area for liquid filling and then reach the capping area, the push-pull cylinder 602 is started, and the push block 604 is driven to push the bottle cap onto the bottle to complete capping. Then the bottles reach the cap screwing area. The cap screwing inductor 707 senses the bottle body, and the cap screwing clamp 708 pops out through the motor and clamps the bottle body. The lifting rod 401 descends to drive the cap screwing device 403 to descend close to the bottle cap. At the same time, the output end of the telescopic motor 405 in the cap screwing device 403 moves upward, driving the cone 4032 to move upward to expand the covering area of the cap screwing gripper 4033. After the cap screwing gripper 4033 reaches the position of the bottle cap, the lifting rod 401 stops descending. At the same time, the output end of the telescopic motor 405 moves downward, driving the cone 4032 to move downward, and the cap screwing gripper 4033 grabs the bottle cap. The three cap screwing grippers 4033 are connected to each other by springs 4034, ensuring that the cap screwing grippers 4033 will not loosen during cap screwing.

[0037] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
