Sterilized paper packaging bag punching processing production line

Abstract

The invention relates to the field of sterilized paper packaging bag production, in particular to a sterilized paper packaging bag punching processing production line. The sterilized paper packaging bag punching processing production line comprises a rack, and further comprises a paper pre-opening mechanism, a paper opening mechanism, a punching mechanism and a punching adjusting mechanism; and the punching adjusting mechanism comprises clamping strips located in the middle of the inner side of a punching groove, the portions, located in a punching base, of the lower ends of the clamping strips are connected with a connecting rod, the outer side faces of the clamping strips are sleeved with a driven gear ring, and the outer side of the driven gear ring meshes with a drive gear ring. According to the sterilized paper packaging bag punching processing production line, the paper pre-opening mechanism cooperates with the paper opening mechanism to open paper, the punching requirements of packaging paper with different size lengths can be conveniently met, and the problem that the paper is torn due to the fact that the size is too large, or the using effect is poor due to the fact thatthe size is too small is avoided; and in addition, the punching adjusting mechanism adjusts the punching inner diameter size and is used for adapting to punching treatment of different sizes, the punching effect of the packaging paper is improved, adjusting is convenient, and the punching processing efficiency of the packaging paper and the precision are high.

Description

technical field [0001] The invention relates to the production of sterilized paper packaging bags, in particular to a perforated production line for sterilized paper packaging bags. Background technique [0002] During the production process of the sterilization packaging bag, the paper needs to be spread out first, and after being flattened by the pressure roller, the two sides of the paper are folded by the folding equipment, so that the two sides of the paper are folded towards the middle respectively, forming two sides of the upper and lower sides. After the folding is completed, it is necessary to use the pressure roller and the guide roller to flatten and guide the folded edge to make the folded paper flat, and then to open the hole in the middle of the lower layer of the paper. After the hole is completed , and then apply glue to the folded and overlapping positions of the two sides, so that the folded edges are sealed and bonded, and then undergo heat sealing, edge s...

Problems solved by technology

[0003] However, in the production and processing process of the existing sterilized packaging bag, when the packaging bag paper is perforated, the equipment for opening the paper on the production line is not perfect enough. The location where the spreader is installed is far away from the hole-opening device, and when the hole is processed, if the paper is long, it is easy to tear the paper or affect the hole-opening effect; if the paper is short, the spreader will not work , and because the hole diameters are different for different sizes of paper, although the hole head has been replaced, the punching size of the corresponding hole head cannot be adjusted. Larger or smaller size will affect the opening quality
