[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-4As shown, the utility model provides a technical solution: a liquid filling and capping machine, comprising a processing table 1, a notch 101 is provided at the top of the processing table 1, a conveyor 2 is installed inside the notch 101, a plurality of straight slots 102 are provided at the top of the processing table 1, and a clamping mechanism for clamping the filled bottle is provided inside each straight slot 102, the clamping mechanism comprising a cylinder 3, the cylinder 3 is fixedly installed at the inner side end of the straight slot 102, the side end of the cylinder 3 is fixedly connected to a connecting plate 301, the top side end of the connecting plate 301 is fixedly connected to a splint 302, the outer shape of the splint 302 is arranged in an arc shape, by placing the filled bottle on the conveyor 2 and transmitting it to the bottom end of the capping machine 7, through the setting of the clamping mechanism, after starting the two groups of cylinders 3, the two groups of cylinders 3 push the two groups of connecting plates 301 and the splint 302 to move, at this time the two groups The splint 302 can clamp and fix the side end of the filling bottle. Since the two groups of splints 302 are arc-shaped, they can be easily fitted on the side wall of the filling bottle, making the splint 302 clamped more firmly. The top of the processing table 1 is fixedly connected with two groups of fixing frames 4. The tops of the two groups of fixing frames 4 are provided with adjustment mechanisms. A mounting frame 6 is provided between the tops of the two groups of adjustment mechanisms. The adjustment mechanism can facilitate the adjustment of the height of the mounting frame 6, and can be used for screwing caps on liquid filling bottles of various heights. Several empty slots 601 are provided inside the mounting frame 6. A capping machine 7 is fixedly installed on the top of the mounting frame 6. The capping machine 7 can realize the screwing of caps on liquid filling bottles. The capping machine 7 is consistent with the capping in the application with application number CN202321384123.0, and belongs to the existing technical structure, so it will not be repeated here.

[0022] As an implementation method in this embodiment, Figure 2 、 Figure 3 and Figure 4As shown, the adjustment mechanism includes several round rods 401, each round rod 401 is fixedly connected to the top of the fixing frame 4, each round rod 401 is inserted into the empty slot 601, and the outer end of each round rod 401 is sleeved with a spring 1 403, and a fixing plate 402 is fixedly connected between the tops of each round rod 401, and a plurality of mounting slots 404 are provided inside the fixing plate 402, and a limiting component is provided inside each mounting slot 404, and the limiting component includes a spring 2 5, and the spring 2 5 is fixedly connected to the inner side end of the mounting slot 404, and the side end of the spring 2 5 is fixedly connected to the rectangular plate 501, and the side end of the rectangular plate 501 is fixedly connected to the limiting block 502, and the side end of the mounting frame 6 is provided with a plurality of limiting slots 602, and the limiting block 502 is adapted to the plurality of limiting slots 602, and the bottom end of the limiting block 502 is sloped. In implementation, when it is necessary to fill liquid bottles of different heights, When the cover is screwed, the mounting bracket 6 is pulled upward with force. At this time, the bottom of each mounting groove 404 and each fixing plate 402 cooperate to squeeze and contract each spring 1 403. At this time, after the mounting bracket 6 moves up, since the bottom end of each limit block 502 is sloped, it is convenient for the limit groove 602 to press the limit block 502 toward the mounting groove 404. At this time, the rectangular plate 501 presses the spring 2 5 to contract. When the mounting bracket 6 continues to be pulled upward, after the limit block 502 passes the next limit groove 602, the spring 2 5 can push the rectangular plate 501 to drive the limit block 502 to rebound. At this time, the limit block 502 can be inserted into the next limit groove 602. After the mounting bracket 6 is released at this time, the spring 1 403 pushes the bottom end of the empty groove 601 to apply a downward force to the mounting bracket 6, and the limit block 502 is limited in the limit groove 602, thereby realizing the adjustment and fixation of the position of the mounting bracket 6.

[0023] Working principle: By placing the filled bottles on the conveyor 2 and conveying them to the bottom end of the capping machine 7, through the setting of the clamping mechanism, after starting the two groups of cylinders 3, the two groups of cylinders 3 push the two groups of connecting plates 301 and the clamping plates 302 to move. At this time, the two groups of clamping plates 302 can clamp and fix the side ends of the filled bottles. Since the two groups of clamping plates 302 are arc-shaped, they can be easily fitted on the side walls of the filled bottles, making the clamping of the clamping plates 302 more secure. Then the liquid filling bottles can be capped by starting the capping machine 7.

[0024] When it is necessary to screw the caps on the liquid filling bottles at different heights, the mounting bracket 6 is pulled upward with force. At this time, the bottom of each mounting groove 404 and each fixing plate 402 cooperate to squeeze and shrink each spring 1 403. At this time, after the mounting bracket 6 moves up, since the bottom end of each limit block 502 is sloped, it is convenient for the limit groove 602 to press the limit block 502 to move toward the mounting groove 404. At this time, the rectangular plate 501 presses the spring 2 5 to shrink. When the mounting bracket 6 continues to be pulled upward, the limit block 502 passes the next limit groove 602, and the spring 2 is retracted. The second spring 5 can push against the rectangular plate 501 to drive the limit block 502 to rebound. At this time, the limit block 502 can be inserted into the next limit slot 602. At this time, after the mounting bracket 6 is released, the first spring 403 pushes against the bottom end of the empty slot 601 to apply a downward force to the mounting bracket 6, and the limit block 502 is limited in the limit slot 602, thereby realizing the adjustment and fixation of the position of the mounting bracket 6. Therefore, the present device can adjust the height of the mounting bracket 6 on which the capping machine 7 is installed, and can be used for capping liquid filling bottles of various heights, making the application range of the capping machine 7 more extensive.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
