Rounded corner edge folding machine

Abstract

The invention discloses a rounded corner edge folding machine, and belongs to the technical field of rounded corner edge folding equipment. The rounded corner edge folding machine comprises an edge folding workbench, a cardboard feeding device, an edge folding bearing device, a down pressing edge folding device, a reciprocating sticking device and a finished product discharging device, the outputdirection of the down pressing edge folding device is vertically downward, the finished product discharging device is installed on the edge folding workbench and beside the edge folding bearing device, and the output direction of the finished product discharging device is perpendicular to the feeding direction of the cardboard feeding device. According to the rounded corner edge folding machine, When the edge folding of the cardboard is carried out, the folded edge with right angle edge can be transformed into a plurality of tooth-groove-shaped structures, so that the folding stress of the folded edge is reduced, the occurrence of folding phenomenon caused by the stack forming of the folding edge at a corner is further avoided, the damage of the paper at the corner is avoided, and the roundness degree of the folding paper at the corner of the hard board is improved.

Description

technical field [0001] The invention relates to the technical field of corner-folding equipment, in particular to a corner-folding machine. Background technique [0002] In many paper-packaged products, the cover of the product is mostly made of hard cardboard. During the production process, a layer of paper is wrapped outside the cover board to improve the service life of the cover, such as dictionaries and classical books. Yes, when the equipment in the prior art wraps the paper on the cover board, because the material of the cover board is relatively hard, when wrapping the corner of the cover board, the corners will not be round, easy to produce wrinkles, and pile up , backlogged together, in severe cases, it will also cause damage to the paper to be wrapped, so it is urgent to design a fillet folding machine to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a round corner folding machine to solve the te...
