Fully edge turning method for tissues of blank boxes and fully edge turning mechanism adopting fully edge turning method

Abstract

A fully edge turning method for tissues of blank boxes is applied to a paper box forming machine and includes steps of conveying the tissues of a blank box from top to bottom after the tissues are positioned and adhered, realizing control by front edge turning tools and rear edge turning tools via expansion and contraction of front edge turning cylinders and rear edge turning cylinders, realizing first front box wide full edge turning and then second rear box wide full edge turning for edge turning portions of the tissues, completely overlaying and covering first fully turned edges by second fully turned edges, and realizing comprehensive edge turning of the blank box in the width direction. A fully edge turning mechanism adopting the fully edge turning method is characterized in that the front box wide edge turning cylinders (1) are mounted at two lateral edges of a front box wide working seat (18), the front box wide edge turning tools (3) are mounted at outer ends of piston rods of the front box wide edge turning cylinders, the rear box wide edge turning cylinders (5) are mounted at two lateral edges of a rear box wide working seat (19), and the rear box wide edge turning tools (4) are mounted at outer ends of piston rods of the rear box wide edge turning cylinders. By the aid of the fully edge turning method and the fully edge turning mechanism, lateral surfaces of the blank box in the width direction look flat and thick, and cannot be uneven, the integral attractiveness of a paper box is improved, and requirements of high-end customers are met completely.

Description

technical field [0001] The invention relates to a carton forming method and a forming machine thereof, in particular to a method for folding wide-side ears on the surface paper of a blank box and an ear-folding mechanism thereof. Background technique [0002] At present, blank boxes for cartons (such as shoe boxes, shirt boxes, gift boxes, mobile phone boxes, etc.) The box and the surface paper (the glued surface paper is under the blank box) are positioned and glued, and then transported to the pasting forming mechanism through the extraction mechanism and the feeding mechanism for pasting (including the action of folding the ears at the wide side) to form the finished carton. Among them, the ear folding method of the blank box face paper is through the linkage of the cam, connecting rod and sliding rod, and the face paper under the blank box is folded in the width direction of a small piece on the widthwise two sides of the blank box by two ear-folding knives. (to prevent...

Problems solved by technology

Among them, the ear folding method of the blank box face paper is through the linkage of the cam, connecting rod and sliding rod, and the face paper under the blank box is folded in the width direction of a small piece on the widthwise two sides of the blank box by two ear-folding knives. (to prevent the four corners of the blank box from leaking light), so that the width of the blank box is uneven, and it looks uneven, which affects the overall aesthetics of the carton and does not meet the requirements of high-end customers.
