[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Figures 1 to 5 An embodiment of a bottle plugging and aeration plate 1 of the present invention is shown. The bottle plugging and aeration plate 1 is used to fill inert gas into the bottle body 2 and the rubber plug 3 before plugging. The bottle plugging and aeration plate 1 comprises a front oxygen-discharging and aeration section 11 and a rear oxygen-isolating and aeration section 12. The front oxygen-discharging and aeration section 11 is provided with at least one oxygen-discharging and aeration hole 111 on the upper plate surface and the lower plate surface, and the rear oxygen-isolating and aeration section 12 is provided with a plugging groove 121 which passes through from top to bottom, and a plurality of oxygen-isolating and aeration holes 122 are provided on two opposite inner sides of the plugging groove 121. The bottle plugging and aeration plate 1 has a rear oxygen-isolating plugging section 12. When the bottle mouth of the bottle body 2 is plugged in the plugging groove 121 of the rear oxygen-isolating plugging section 12, since a plurality of oxygen-isolating gas-filling holes 122 are provided on the two opposite inner sides of the plugging groove 121, the oxygen-isolating gas-filling holes 122 can fill the plugging groove 121 with inert gas. The gas filling through the oxygen-isolating gas-filling holes 122 is horizontal gas filling, so that the rubber plug 3 always maintains an inert gas environment between the rubber plug 3 and the bottle mouth during the process of inserting the rubber plug 3 into the bottle mouth, thereby preventing air from entering the bottle body 2 during the plugging process, and meeting the requirement of lower residual oxygen content. The bottle plugging and aeration plate 1 has a simple structure, is easy to operate, and can meet the requirement of lower residual oxygen content.

[0035] In this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the upper plate surface of the front zone oxygen exhaust and inflation section 11 is provided with a first arcuate groove 13 for the rubber plug 3 to pass through, and the lower plate surface of the front zone oxygen exhaust and inflation section 11 is provided with a second arcuate groove 14 for the bottle mouth to pass through, the first arcuate groove 13 and the second arcuate groove 14 are symmetrically arranged, and the oxygen exhaust and inflation hole 111 is arranged on the bottom surface of the first arcuate groove 13 or the second arcuate groove 14. Specifically, the bottom surface of the first arc groove 13 or the second arc groove 14 is provided with a plurality of oxygen exhaust and gas filling holes 111. During the oxygen exhaust and gas filling process, the rubber plug 3 moves along the first arc groove 13, and the bottle mouth moves along the second arc groove 14, and the rubber plug 3 and the bottle mouth move synchronously and are aligned up and down. When the rubber plug 3 moves along the first arc groove 13, the oxygen exhaust and gas filling holes 111 on the bottom surface of the first arc groove 13 are filled with inert gas, thereby discharging oxygen in the rubber plug 3. When the bottle mouth moves along the second arc groove 14, the oxygen exhaust and gas filling holes 111 on the bottom surface of the second arc groove 14 are filled with inert gas, thereby discharging oxygen in the bottle body 2.

The oxygen-isolating gas-filling holes 122 on each side are spaced apart along the extension direction of the plugging groove 121, so that a relatively high inert gas environment is maintained in the plugging groove 121. The curvature of the plugging groove 121 is consistent with the curvature of the plug suction plate 4, so that when the rubber plug 3 is inserted into the bottle mouth of the bottle body 2, the rubber plug 3 and the bottle mouth can also move along the plugging groove 121, so that the bottle body 2 is plugged during the transportation process, and the plugging is performed in the inert gas environment in the plugging groove 121.

[0037] In this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, a first air channel 15 and a second air channel 16 are provided in the bottle plugging and inflating plate 1, and a first inflating nozzle 17 and a second inflating nozzle 18 are provided on the bottle plugging and inflating plate 1. The oxygen-discharging and inflating hole 111 is communicated with the first inflating nozzle 17 through the first air channel 15, and the oxygen-isolating and inflating hole 122 is communicated with the second inflating nozzle 18 through the second air channel 16. Specifically, the second air channel 16 includes a first arc-shaped channel 161 and a second arc-shaped channel 162, and the first arc-shaped channel 161 and the second arc-shaped channel 162 are respectively located on both sides of the plugging groove 121, and the oxygen-isolating and inflating hole 122 on one side of the plugging groove 121 is communicated with the second inflating nozzle 18 through the first arc-shaped channel 161, and the oxygen-isolating and inflating hole 122 on the other side of the plugging groove 121 is communicated with the second inflating nozzle 18 through the second arc-shaped channel 162.

[0038] In this embodiment, Figure 1 and Figure 3 As shown, the bottle plugging and inflating plate 1 is provided with an adjustment hole 19 for adjusting the position of the bottle plugging and inflating plate 1, and the bottle plugging and inflating plate 1 can be fixed by passing a bolt through the adjustment hole 19, and the bottle plugging and inflating plate 1 can be rotated around the bolt to adjust the position, so that the bottle plugging and inflating plate 1 is easy to install and convenient to adjust the position.

[0039] Figures 5 to 10 An embodiment of the bottle stoppering mechanism of the present invention is shown, which includes a plug suction plate 4 for negative pressure adsorption and positioning of the rubber stopper 3, a lifting track 5 and a dial wheel 6 with a limiting groove 61, the lifting track 5 is arranged around the lower part of the dial wheel 6, the plug suction plate 4 and the dial wheel 6 are coaxially fixed up and down and rotate synchronously with the dial wheel 6, the bottle body 2 is limited in the limiting groove 61 and rotates synchronously with the plug suction plate 4, and rises along the lifting track 5 to combine with the rubber stopper 3 adsorbed and positioned on the plug suction plate 4, the bottle body stoppering mechanism also includes a bottle stoppering inflation plate 1, the bottle stoppering inflation plate 1 is located between the plug suction plate 4 and the dial wheel 6, and close to the junction of the bottle body 2 and the rubber stopper 3.

[0040] In this embodiment, the lifting track 5 is arranged around the lower part of the limiting groove 61 of the dial wheel 6. The lifting track 5 is provided with a circular track surface 51 with a slope, that is, the track surface 51 in contact with the bottom of the bottle body 2 has a height difference. The bottle body 2 is driven by the dial wheel 6 to slide along the lifting track 5 from the lower position of the track surface 51 to the higher position to form a lifting track, so as to realize the combination of the bottle body 2 and the rubber plug 3 (such as Fig.10 As shown in the figure, the track surface 51 is located below the plugging groove 121, so that the bottle body 2 is plugged in the plugging groove 121. When the bottle body 2 rises along the lifting track 5, the oxygen-isolating air hole 122 inflates the space between the bottle mouth and the plug 3 to prevent the plug 3 from being inserted into the bottle body 2. The oxygen is prevented from entering the plug 3 and the bottle body 2 during the process of inserting the plug 3 into the bottle body 2, thereby greatly reducing the residual oxygen content in the bottle body 2 after the plug is sealed.

[0041] In this embodiment, Figure 6 and Figure 7 As shown, a bottle guide fence 7 for guiding the bottle body 2 into the limiting groove 61 is provided on the outer side of the thumbwheel 6. At the same time, the bottle guide fence 7 can guide the rubber plug 3 into the first arc-shaped groove 13 and guide the bottle mouth into the second arc-shaped groove 14.

Specifically, the top end of the support rod 81 penetrates into the adjustment hole 19 of the bottle plugging and inflating plate 1, and the nut 9 is fixed on the top end of the support rod 81 and presses the bottle plugging and inflating plate 1 onto the support rod 81. The fixing method of the bottle plugging and inflating plate 1 facilitates the adjustment of the position of the bottle plugging and inflating plate 1, and ensures that each oxygen exhausting and inflating hole 111 and the oxygen isolating and inflating hole 122 correspond to the corresponding bottle body 2 or rubber plug 3.

[0043] The working principle of the bottle plugging mechanism of the present invention is:

[0044] When the bottle body 2 is transported from the bottle transport block to the limiting groove 61 corresponding to the thumbwheel 6 (such as Figure 1 As shown in the figure, when the bottle body 2 and the rubber plug 3 are in the front oxygen exhaust and gas filling section 11, the oxygen exhaust and gas filling holes 111 on the upper and lower surfaces of the front oxygen exhaust and gas filling section 11 vertically fill the bottle body 2 and the rubber plug 3 with inert gas; with the rotation of the dial wheel 6, the bottle body 2 and the rubber plug 3 are in the plugging groove 121 of the rear oxygen isolation plugging section 12, and the oxygen isolation gas filling holes 122 horizontally inflate the space between the bottle mouth and the rubber plug 3 to prevent the plug 3 and the bottle body 2 from being oxygenated during the insertion of the rubber plug 3 into the bottle body 2, thereby greatly reducing the residual oxygen content in the bottle body 2 after the plugging and sealing. When the bottle body 2 is plugged, it is moved out from the open end of the plugging groove 121 with the rotation of the dial wheel 6 (as shown in the figure). Fig.10 shown).
