Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper product production equipment, in particular to a covering structure of a folder gluing machine. Background Art
[0002] As described in the published patent CN113715406B, with the improvement of people's quality of life, the packaging and transportation of various items are inseparable from cartons. The cartons are usually produced in a pressed and folded state for easy transportation, and are opened to form a box body when used. The cartons are folded by a folding machine to form a certain shape for packaging.
[0003] The cardboard folding process is achieved by twisting a nylon rod or a belt or a combination of the two, and the top wall of the belt is flipped 180 degrees so that when the cardboard passes through the folded belt, both sides of the cardboard are folded upward under the limiting action of the belt to fold the cardboard.
[0004] Regarding the above-mentioned related technologies, the inventors believe that: when folding the cardboard, the folding machine folds the two sides of the cardboard and reverses them 180 degrees. After folding, both sides of the cardboard are formed into a certain shape by the creases. Later, the two sides of the folded cardboard need to be manually glued together, which makes the folding and gluing efficiency of the cardboard low.
[0005] In summary, in the existing box gluing technology, the two sides of the folded cardboard will partially overlap at the junction, and then the overlapping parts of the two sides of the cardboard will be glued together to complete the box gluing operation. However, since the two sides of the cardboard will partially overlap, the synchronous folding of the two sides of the cardboard will cause mutual extrusion and collision to cause deformation, affecting the forming quality of the box body, so it is necessary to design the folding process of the two sides of the cardboard asynchronously to improve the production quality.
