Outer bag charging device used for full automatic packaging machine packing tea by inner and outer vacuum bags

Abstract

The invention discloses an outer bag charging device used for a full automatic packaging machine packing tea by inner and outer vacuum bags, comprising an outer bag conveying mechanism and an inner bag folding propelling mechanism which can close to each other by movement, wherein, an outer bag placing device and an outer bag opening mechanism are respectively arranged above the outer bag conveying mechanism; the outer bag conveying mechanism shifts between the outer bag placing device and the outer bag opening mechanism; the outer conveying mechanism and the outer bag opening mechanism are correspondingly provided with a bag taking sucker and a bag opening sucker by lifting; the inner bag folding propelling mechanism comprises an inner bag adaptor the front part and the rear part of which are correspondingly provided with an inner bag folding opening and an inner bag propelling mechanism; the front part of the inner bag folding opening is provided with an outer bag expanding mechanism which can be opened and closed; and the inner bag propelling mechanism comprises a propelling component which can pass through the adaptor inner chamber and the inner bag folding opening, and pass in and out of the inside of the expanded outer bag opening mechanism. The invention can automatically and continuously finish the operation process of inner bag folding and place the folded inner bag into the outer bag rapidly and stably, and greatly improves automation degree and production efficiency of the inner bag and outer bag vacuum packing operation.

Description

technical field [0001] The invention belongs to full-automatic tea packaging equipment, in particular to an outer bag charging device for a full-automatic tea packaging machine with inner and outer vacuum bags. Background technique [0002] In order to prolong the shelf life and freshness of tea, prevent moisture and odor volatilization, facilitate storage and better adapt to the needs and use of consumers at different levels, tea is usually vacuum-packed with inner and outer bags, and is marketed in small packages of 5-10 grams. At present, the vacuum packaging method of the inner and outer bags is: firstly put the manually or automatically measured tea into the three-side-sealed film inner bag, and then manually fold the mouth of the inner bag after filling and put it into the outer bag , and finally put the filled outer bag into the vacuum packaging machine for vacuum-sealed packaging to achieve vacuum packaging of the inner and outer bags. The existing packaging process...
