Abstract

The invention discloses a bottom sealing strip edge-folding and punching device of a bag making machine. The device comprises a bottom strip edge folding assembly and a bottom strip punching assembly,wherein the bottom strip edge folding assembly comprises a door-shaped frame and a bottom plate, the door-shaped frame and the bottom plate are arranged on a bag making machine body, a cross beam ofthe door-shaped frame is provided with a connecting base, the connecting base is connected with an edge folding vertical plate through a connecting rod at the lower side, two bottom strip guide wheelsare arranged at the front end of the edge folding vertical plate, edge folding ejector rods are arranged on the two sides of the edge folding vertical plate, an edge folding pressing plate is connected to the bottom surface of the edge folding vertical plate, the edge folding pressing plate and the bottom plate form a bottom sealing strip guide space, the bottom strip punching assembly comprisesa sliding rod frame arranged on the bag making machine body, and a first punching assembly and a second punching assembly are arranged on the sliding rod frame in a staggered mode. The bottom sealingstrip edge-folding and punching device is simple in operation and ingenious in structure, a bottom sealing strip is effectively protected in the edge folding process, and the bottom sealing strip is prevented from being scratched in the edge folding process.

Description

technical field [0001] The invention relates to the technical field of bag-making machines, in particular to a bag-making machine bottom-sealing belt folding edge punching device. Background technique [0002] The bag making machine is a special equipment for making packaging bags. It is widely used in the production of packaging bags made of various plastics, paper and other materials. The process of making packaging bags by the bag making machine is: conveying the film, overlapping and folding the film, after overlapping The thin film is heated longitudinally and horizontally to form a structure connected by multiple small bags, and finally cut to form multiple independent small bags. [0003] The middle-sealed packaging bag needs to be folded before the middle-seal heat-sealing, that is, the two sides of the packaging film are closed in the middle at the same time. The closed packaging film passes through the middle sealing mechanism to heat seal the two sides to form a ...
