Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a corrugated paper box folding and pressing device. Background Art

[0002] Corrugated paper boxes are made of corrugated cardboard through die-cutting, creasing, nailing or gluing. When the corrugated paper is folded, a folding plate is generally used to press an indentation on the surface of the corrugated paper, so as to facilitate folding the corrugated paper into a box. In order to facilitate the extrusion, a corrugated box folding device is needed to press an indentation on the surface of the corrugated cardboard.

[0003] However, most of the existing corrugated cardboard folding and pressing devices can only indent the cardboard by setting a pressing plate inside the device, and the pressing plate is mostly a fixed single structure. When indenting the corrugated cardboard, it is necessary to manually adjust the paper sheet or the pressing plate repeatedly to complete the indentation process, and the work efficiency is low; at the same time, when performing the indentation process, the conventional corrugated cardboard folding and pressing device often sets pressing plates on both sides to facilitate the limit fixation of the corrugated cardboard. When encountering the cut corrugated cardboard with uneven two sides, it is easy to encounter the problem that the clamping position of the pressing plate blocks the indentation line of the indentation structure, and it is necessary to manually adjust it many times to complete the work. Therefore, we propose a corrugated cardboard folding and pressing device to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a corrugated cardboard box folding device to solve the problem raised by the above-mentioned background technology that the corrugated cardboard box folding device currently on the market needs to be manually adjusted repeatedly and multiple times between the position of the paper sheet or the pressing plate and the clamping position of the pressing plate, thereby blocking the indentation line of the indentation structure.
