Sharp-bottomed paper bag forming machine

Abstract

The invention relates to a sharp-bottomed paper bag forming machine which comprises a feeding mechanism, a puncturing mechanism, an edge glue coating mechanism, a forming mechanism, a snapping mechanism, a conveying mechanism, a bottom glue coating mechanism, a bottom folding mechanism and a collecting mechanism which are sequentially arranged, and is characterized in that a forming adjusting mechanism is arranged between the forming mechanism and the puncturing mechanism; the forming adjusting mechanism comprises a paper folding plate mounting base connected with the top of a paper folding plate of the forming mechanism, the paper folding plate mounting base is erected on the puncturing mechanism through oppositely-arranged fixing bases, and a left-right adjusting driving source is arranged on one side of each fixing base. A left-right adjusting mechanism capable of adjusting the relative position of the paper folding plate mounting seat between the two fixing seats through a left-right adjusting driving source is arranged between the fixing seats and the paper folding plate mounting seat, the conveying mechanism is an air suction type conveying mechanism, and the air suction type conveying mechanism comprises an air suction conveying belt and an air suction box, and air suction holes are evenly distributed in the surface of the air suction conveying belt.

Description

technical field [0001] The invention relates to the field of paper bag forming machines, in particular to a pointed bottom paper bag forming machine. Background technique [0002] The common oil-proof paper bags for food packaging on the market include square-bottom oil-proof paper bags and pointed-bottom grease-proof paper bags. The common oil-proof paper bags with bottom are roast duck oil-proof paper bags and oil-proof paper bags with fried chestnuts. First of all, in terms of material, the oil-proof paper bags with pointed bottom are made of coated paper. The manufacturers of oil-proof paper bags can get the raw materials directly. It is made into a bag and does not need to be coated again. This kind of oil-proof paper bag has a size limit when it is customized, and the side width cannot exceed 5 cm, while the square-bottom oil-proof paper bag is made of kraft paper or white paper by artificial lamination. The oil-proof paper bag made by this process has no size limit, ...

Problems solved by technology

[0004] However, there are many deficiencies in the equipment of this structure. For example, when the paper tube forming part forms the paper into a paper tube, if there is a deviation before the paper tube is formed, it is necessary to stop the machine, adjust the paper, and restart the test until the formed paper tube is free. As far as the deviation is concerned, the way of shutdown adjustment greatly affects the production efficiency;

[0005] In addition, the paper-feeding force of the paper-feeding part is fixed, no matter how big the paper is, it only provides a fixed paper-feeding force, and the paper is not fixed on the paper-feeding part, and it is not conducive to the bottom of the paper after the deviation occurs. Forming and collection, it is necessary to improve this
