Full-automatic adjustable paper box impressing devices

Abstract

The invention provides full-automatic adjustable paper box impressing devices. A conveying belt set comprises at least two parallelly arranged conveying belts with the same rotating direction and used for driving a paperboard of a paper box to move, and a gap is arranged between the conveying belts; a line pressing mechanism comprises an installation frame and at least two line pressing devices installed on the installation frame, the two ends of the installation frame are installed on a rack and capable of moving in the vertical direction of the rack, the line pressing devices are located in the gap between the conveying belts and penetrate through the gap, each line pressing device comprises a supporting rod, and a wedge-shaped line pressing cutter is arranged at the end, close to the conveying belts, of each supporting rod; a line pressing plate is located above the line pressing mechanism, the two ends of the line pressing plate are installed on the rack and capable of moving in the vertical direction of the rack, a plurality of grooves matched with the wedge-shaped line pressing cutter are formed in the line pressing plate, and the shortest distance between the wedge-shaped line pressing cutter and the line pressing plate is smaller than the thickness of the paperboard of the paper box. The full-automatic adjustable paper box impressing devices have the advantages that the structure is simple, the depth of the impressing can be controlled, the impressing quality is high, and the work efficiency is high.

Description

technical field [0001] The invention relates to the technical field of packaging equipment, in particular to a fully automatic adjustable carton creasing device. Background technique [0002] The indentation device is an important part of the printing slotting machine. The corrugated cardboard is pressed out by the indentation device, and the corrugated cardboard is folded and formed by the indentation line. Therefore, the indentation of the corrugated cardboard is the key process of corrugated box forming. At present, the indentation device of the corrugated box printing and slotting machine usually has the inner side of the corrugated paper facing the indentation rib, and the outer side of the corrugated paper is facing the indentation groove. This is the commonly used corrugated paper dark line concave design. The concave design needs to adjust the depth and width of the depression according to the thickness and strength of corrugated paper, and the indented cartons gener...

AI Technical Summary

Problems solved by technology

However, when the utility model is used to indent cartons, the depth of the indentation cannot be controlled, and multiple marks cannot be pressed at one time. The adjustment is poor and the work efficiency is low. Moreover, the device cannot adapt to the indentation of cartons of different sizes, and the application range is small.
