[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0029] Please see Figures 1-3 This is the first embodiment of the present invention.

[0030] This embodiment provides a filling head adjustment mechanism for a linear filling machine, including:

[0031] The frame 1 has an adjustment mechanism 101 on its inner side, a positioning mechanism 102 on the top of its inner side, a lifting mechanism 103 on its side, and a fixing mechanism 104 on the bottom of its lifting mechanism 103.

[0032] The adjustment mechanism 101 includes a control console 2 installed at one end of the inner side of the frame 1. A lead screw 3 is rotatably installed inside the control console 2. A threaded cylinder 4 is rotatably installed on the lead screw 3 through a threaded engagement. A moving platform 6 is installed at the other end of the inner side of the frame 1. A slide rod 7 is fixed inside the moving platform 6. A slide cylinder 8 is slidably installed on the slide rod 7. A telescopic frame 5 is fixed between the slide cylinder 8 and the threaded cylinder 4. A support platform 10 is rotatably installed on the bottom side of the telescopic frame 5. Cylinder bodies 11 are fixed at both ends of the support platform 10. A servo motor 9 is fixed on the side of the control console 2. The output end of the servo motor 9 passes through the control console 2 and is fixedly connected to the lead screw 3.

[0033] Specifically, the positioning mechanism 102 includes a limiting rod 12 symmetrically fixed to the top of the inner side of the frame 1, and sliding seats 13 symmetrically fixed to the top ends of the control console 2 and the moving platform 6. The sliding seats 13 are slidably connected to the limiting rod 12. A threaded rod 14 is rotatably installed at the center of the top of the inner side of the frame 1. A positioning seat 16 is fixed at the center of the top side of the moving platform 6. The positioning seat 16 is rotatably connected to the threaded rod 14 through a threaded engagement. A drive motor 15 is fixed to the top of the side of the frame 1. The output end of the drive motor 15 passes through the frame 1 and is fixedly connected to the threaded rod 14.

[0034] Furthermore, through the structure of the threaded rod 14, the filling head on the bottom side of the support platform 10 can be moved horizontally simultaneously before filling, accurately moving it to the top side of the bottle mouth for subsequent filling.

[0035] In use, the servo motor 9 is controlled to drive the output screw 3 to rotate. Since the threads at both ends of the screw 3 are in opposite directions, the threaded cylinder 4 moves along the screw 3 in the opposite direction, thereby lengthening or shortening the telescopic frame 5 and changing the distance between the support platforms 10 on the bottom side of the telescopic frame 5. According to the size of the bottle to be filled, the distance between the filling heads is quickly adjusted to a suitable distance. Then, the drive motor 15 is controlled to drive the output threaded rod 14 to rotate, thereby pushing the control console 2 and the moving platform 6 to move simultaneously along the limit rod 12 with the cooperation of the positioning seat 16, causing the filling head to move to the top side of the bottle mouth, thereby positioning the bottle to be filled and accurately performing the filling process.

[0036] In summary, by setting the adjustment mechanism 101, the servo motor 9 drives the lead screw 3 to rotate, which in turn drives the telescopic frame 5 to extend and retract to the required length. This adjusts the filling heads, which are evenly distributed on the bottom side of the telescopic frame 5, to a suitable spacing, so that the filling machine can quickly switch when changing filling bottles, ensuring that the filling efficiency of the filling machine does not decrease. Example

[0037] Please see Figures 4-5 This is the second embodiment of the present utility model.

[0038] Specifically, the lifting mechanism 103 includes a fixed plate 22 fixed to the top of the side of the control console 2 and the moving platform 6. An electric telescopic rod 23 is fixed to the bottom of the fixed plate 22. A telescopic cylinder 17 is slidably installed inside the cylinder 11. A controller 24 is fixed to one end of the top side of the frame 1. The controller 24 is connected to the electric telescopic rod 23. A filling head body 18 is fixed to the bottom of the telescopic cylinder 17. A telescopic connecting rod 19 is fixed between the filling head bodies 18. A bracket 20 is fixed to each of the two filling head bodies 18. A connecting plate 21 is fixed to the center of both ends of the bracket 20. The bottom end of the electric telescopic rod 23 is fixedly connected to the connecting plate 21. Hollow tubes 25 are symmetrically fixed to the top of the inner side of the frame 1. The hollow tubes 25 are connected to the filling head bodies 18 through a water supply pipe 26.

[0039] Furthermore, the electric telescopic rod 23 drives the support 20 to move up and down, thereby changing the height of each filling head body 18 at the same time. With the cooperation of the telescopic connecting rod 19, the distance between the filling head bodies 18 can be adjusted, thus facilitating the filling of bottles of different sizes.

[0040] Specifically, the fixing mechanism 104 includes mounting seats 28 symmetrically fixed on both sides of the telescopic connecting rod 19, a clamping plate 29 is rotatably mounted on the inner side of the mounting seat 28, an arc-shaped inclined plate 30 is fixed on the inner side of the clamping plate 29, and a torsion spring 31 is fixedly connected between the mounting seat 28 and the top side of the clamping plate 29.

[0041] Furthermore, by cooperating with the torsion spring 31 and the clamping plate 29, the arc-shaped inclined plate 30 on the inner side of the clamping plate 29 can be clamped at the bottle mouth during filling, preventing the bottle mouth from shifting position during the filling process.

[0042] In use, the controller 24 controls the simultaneous operation of the electric telescopic rods 23 on both sides, which, with the cooperation of the connecting plate 21, drive the filling head body 18 inside the bracket 20 to move up and down until the filling head body 18 contacts the bottle mouth and presses against the bottle mouth. At the same time, the bottle mouth pushes the arc-shaped inclined plate 30 to open the clamping plate 29. At this time, with the cooperation of the torsion spring 31, the arc-shaped inclined plate 30 is clamped at the bottle mouth. At this time, drinking water can be filled into the bottle, preventing the bottle mouth from shifting during the filling process and causing waste of drinking water.

[0043] In summary, the lifting mechanism 103 and the fixing mechanism 104 enable the filling machine to fill bottles of different sizes. During the filling process, the bottle mouth can be automatically clamped and fixed to prevent the bottle mouth from shifting, thereby improving the filling efficiency of the filling machine.
