Introduction to the main components of the liquid packaging machine
Currently, the liquid packaging machines usually called are all cavity structures, which consist of an upper vacuum chamber, a lower vacuum chamber and an upper vacuum chamber. , The sealing ring between the lower vacuum chamber is composed. The upper and lower vacuum chambers are generally made of aluminum alloy cast and then milled and processed or stainless steel sheets are folded or molded and then welded and flattened. There are also upper and lower vacuum chambers that use aluminum alloy and stainless steel respectively. Aluminum alloys include ordinary alloys and aluminum-magnesium alloys. The latter is acid and alkali resistant and corrosion resistant, but the cost is relatively high. The aluminum alloy vacuum chamber is milled and processed, and its sealing plane and sealing groove plane are very smooth, and the vacuum chamber has good sealing performance. The thickness of the stainless steel sheet is usually 2-4MM. The thin thickness is easy to deform after the vacuum is pressed, causing the weld to crack, and the vacuum chamber leaks. In addition, a sealing groove is generally set on the surface of the vacuum chamber on the stainless steel. The sealing groove is affected by the processing technology. The flatness is poor, and the sealing performance of the vacuum chamber is correspondingly reduced. Therefore, in some models, the upper vacuum chamber adopts aluminum alloy casting and milling to process the sealed groove, and the lower vacuum chamber adopts thick stainless steel plate to be processed into a flat plate, whichever is better than others. When purchasing, packaging solid, granular and other relatively dry and non-corrosive materials can be made of aluminum alloy, and the packaging contains soup, materials with high salt and acid content.
Use of liquid packaging machine
This package is suitable for soy sauce, vinegar, fruit juice, milk and other liquids. It adopts 0.08mm polyethylene film. Its forming, bag making, quantitative filling, ink printing, sealing and cutting are all automatically performed, and the film is UV sterilized before packaging. , Meet the requirements of food hygiene.
