Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag slitting, in particular to a slitting device for processing paper packaging bags. Background Art

[0002] Paper packaging bags are widely used in daily life and can be used in food, clothing and other industries. However, paper packaging needs to be cut during production to meet processing requirements. Therefore, specific cutting equipment is required to cut paper packaging bags in actual production.

[0003] Through searching, a slitting device for processing paper packaging bags with the publication number CN215943842U belongs to the field of slitting devices. A slitting device for processing paper packaging bags comprises a fixed seat, two groups of fixed plates are fixedly installed on the upper end of the fixed seat, rolling rollers are installed on the side walls of the two groups of fixed plates, and a ring is provided on the side wall of the rolling roller, and a partition plate is fixedly installed on the upper end of the ring, an arc block is fixedly installed on the upper end of one group of fixed plates, and a fixed rod is rotatably connected to the side wall of the arc block, and a plurality of cutting knives are fixedly installed on the side wall of the fixed rod, and a middle lifting plate is fixedly installed on the upper end of the fixed seat, and a plurality of limit rotating grooves are provided on the middle lifting plate, and the limit rotating grooves are rotatably connected to the limit roller, which facilitates the adjustment of the paper packaging bag passing through the rolling roller by raising the height of the limit roller, thereby avoiding the loosening of the paper packaging bag and resulting in inferior packaging bags during cutting, thereby improving the efficiency of the device.

[0004] Based on the above, the inventors have found that the existing slitting devices for processing paper packaging bags usually directly slit paper packaging bags, which makes the paper packaging bags very easy to deviate on the outer surface of the slitting machine, thereby causing the slitting machine to slit the outer surface of the paper packaging bags unevenly, thereby affecting the quality of the paper packaging bags, and requiring staff to manually roll up the slit paper packaging bags, which easily increases the workload of the staff. Therefore, in view of this, the existing structure is studied and improved, and a slitting device for processing paper packaging bags is provided, in order to achieve a more practical purpose.
