Filling machine for beer packed by PET (polyethylene terephthalate) bottle

Abstract

The invention discloses a filling machine for beer packed by PET (polyethylene terephthalate) bottles, which is suitable for PET bottles. The filling machine comprises a stand, a bottle feeding air flue, a bottle rinsing device, a filling device, a cap screwing device, a bottle discharging delivering chain, a transition bottle delivering device and a bottle discharging star wheel, wherein the bottle feeding air flue, the bottle rinsing device, the filling device, the cap screwing device and the bottle discharging delivering chain are arranged on the stand, the transition bottle delivering device connects the bottle feeding air flue, the bottle rinsing device, the filling device and the cap screwing device in series, and the bottle discharging star wheel connects the cap screwing device and the bottle discharging delivering chain together in series. The bottle rinsing device, the filling device, the cap screwing device and a bottle clamp in the transition bottle delivering device are all bottle-neck pincers, and a filling valve in the filing device is a long-tube filling valve. The invention is mainly used for filling beer packed by the PET bottles.

Description

technical field [0001] The present invention relates to a filling machine, in particular to a filling machine for packaging beer with PET bottles. Background technique [0002] As we all know, bottled beer is fragile and explosive, and the cost is relatively high during transportation, and the energy consumption of recycling and washing bottles is high, and there are also potential safety hazards during use. Therefore, packaging beer with environmentally friendly and safe PET bottles will replace glass bottles and become the mainstream packaging method. However, the bottle lifting mechanism in the current glass bottle filling machine adopts a bottom-supporting structure. When filling, the glass bottle is first evacuated, and then it is filled with an ordinary equal pressure filling valve. As we all know, for PET bottles, only the bottleneck part can be clamped, and the other parts are soft, and they will collapse when pressed. Obviously, the above-mentioned lifting mechanis...

AI Technical Summary

Problems solved by technology

As we all know, for PET bottles, only the bottleneck part can be clamped, and the other parts are soft, and they will collapse when pressed. Obviously, the above-mentioned lifting mechanism of the bottom of the bottle cannot be used; moreover, PET bottles cannot be vacuumed. , deflated

Therefore, the current glass bottle filling machine cannot use PET bottles to fill beer, and it has become a top priority to develop a filling machine that uses PET bottles to package beer.
