During this process, it is easy for the cap to be placed unevenly on the bottle or barrel. At this time, if the pressurization operation is continued, it is easy to cause damage to the bottle mouth and the cap, so how to solve this problem needs to be considered. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figures 1-4A capping structure of a pneumatic capping machine includes a movable plate 1, the upper end of the movable plate 1 is fixedly connected to a piston cylinder 4, the upper end of the movable plate 1 is fixedly connected to a pneumatic telescopic rod 2, and the telescopic end of the pneumatic telescopic rod 2 is fixedly connected to the lower end of the upper fixed part of the capping machine frame. Figure 4 As shown, at this time, as the pneumatic telescopic rod 2 is started to extend, the entire movable plate 1 can be moved downward by the reaction force. Two guide holes 3 are symmetrically opened on the movable plate 1, and the guide holes 3 cooperate with the existing guide rod part on the frame;

[0021] Among them, it also includes an adjustable pressing mechanism, which includes a slide groove 7 opened at the lower end of the movable plate 1, a movable bar 8 that can slide left and right is set in the slide groove 7, an L-shaped plate 5 is fixedly connected to the left side of the movable plate 1, and an electric telescopic rod 6 is fixedly connected to the right side of the vertical part of the L-shaped plate 5. The telescopic end of the electric telescopic rod 6 is fixedly connected to the left side of the movable bar 8, and the lower end of the movable bar 8 is fixedly connected to a plurality of guide rings 9. The sizes of the plurality of guide rings 9 are different to adapt to different cover bodies;

[0022] Among them, it also includes a negative pressure adsorption mechanism, which cooperates with an adjustable pressure cover mechanism. The negative pressure adsorption mechanism includes a piston cylinder 4 fixedly connected to the upper end of the movable plate 1, and a piston plate 12 that can slide up and down is arranged in the piston cylinder 4. The piston plate 12 is an iron piston. The upper end of the piston plate 12 is elastically connected to the inner top of the piston cylinder 4 through a spring 13. The inner top of the piston cylinder 4 is fixedly connected to an annular electromagnet 15. A plurality of negative pressure holes 10 are vertically opened on the upper part of the movable bar 8, and a through port 14 is opened on the inner bottom of the piston cylinder 4. The through port 14 cooperates with the plurality of negative pressure holes 10. A rubber ring 11 is fixedly connected to the lower end opening of the through port 14. The lower end face of the rubber ring 11 contacts the upper end face of the movable bar 8, and a ventilation hole is provided on the inner top of the piston cylinder 4.

[0023] It should be noted that the capping structure needs to be used in conjunction with a capping machine that can position different bottles in the middle of the placement part (such as a three-jaw chuck installed in the middle of the placement part), and the bottle caps it is designed for are horizontal and smooth at the top.

[0024] In the utility model, when in use, the bottle body is placed on the placement part of the frame so that the bottle body is located in the middle of the placement part. At this time, the worker puts the upper end surface of the bottle cap into the inner side of the guide ring 9 in the middle and starts the annular electromagnet 15. Since the bottle cap is placed, it is guided and is now located in the middle position, corresponding to the bottle mouth of the bottle body, and is in a horizontal state. After the annular electromagnet 15 is started, the piston plate 12 is moved up and the spring 13 is compressed, so that the space at the bottom of the piston cylinder 4 is in a negative pressure state, which adsorbs the bottle cap. At this time, the pneumatic telescopic rod 2 is started to move the bottle cap down for capping. In this way, the bottle cap can be in a horizontal state and pressed down against the bottle mouth. Compared with the prior art, the situation of pressurization damaging the cap and the bottle mouth due to not placing the bottle in a horizontal state is avoided.

[0025] If different bottle caps are used, the electric telescopic rod 6 can be started to move the movable bar 8 and the corresponding guide ring 9 can be moved to just below the through opening 14. It can be used for different bottle caps and has strong overall adaptability.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
