Abstract

The invention belongs to the technical field of packaging film cutting, and particularly relates to a continuous folding device for a film bag and continuous folding equipment for a film. The continuous folding device for the film bag comprises a mounting vertical plate, two groups of cutting-off and overlapping mechanisms oppositely arranged on the mounting vertical plate, and a driving mechanism, wherein each cutting-off and overlapping mechanism comprises a film guiding-in mechanism, a rotating roller shaft, a cutting-off supporting piece and cutting-off tools; the rotating roller shafts are connected with the driving mechanism; the at least two groups of cutting-off tools are oppositely arranged on each rotating roller shaft; the outer surface of each rotating roller shaft is axially provided with grooves corresponding to the cutting-off tools in the other set of cutting-off overlapping mechanism; a plurality of first air holes are formed in each groove; a plurality of second air holes are formed in the back face of each cutting-off tool or the back face, close to the cutting-off tools, of the corresponding rotating roller shaft; and the first air holes and the second air holes are connected with a pneumatic pump system pipeline. The continuous folding device for the film bag can be beneficial to improving the production efficiency, reducing the cost, and facilitating popularization and application of the paper extraction type plastic film bag in the market, and brings convenience to vast consumers.

Description

technical field [0001] The invention belongs to the technical field of packaging film cutting, in particular to a film bag continuous folding device and film continuous folding equipment. Background technique [0002] Film packaging bags are currently commonly used packaging materials; for example, they need to be used for shopping in shopping malls, which bring greater convenience to citizens' consumption and life. Existing film bag is mainly roll-shaped, and when in use, is torn from the seam (point broken line) that film bag is connected in the middle of film bag. At present, in order for consumers to pick up film bags more conveniently, some shopping malls will use removable film bags. [0003] For example, in the Chinese patent literature, the publication number is CN109677010A, which discloses a cross-retrieval plastic bag packaging structure. Sealing; the side edges of the same side of several overlapping plastic bags are in the same vertical plane. It also disclos...
