Directional automatic folding device for corrugated carton gluing machines

Abstract

The invention discloses a directional automatic folding device for corrugated carton gluing machines. The device comprises a paper pressing assembly and a moving connection assembly, wherein the paper pressing assembly comprises a folding substrate, a folding support arm, a sliding shaft and a paper pressing plate which are sequentially connected; the moving connection assembly comprises a connecting bar, a slide block and an eccentric cam which are sequentially connected; and the folding substrate is arranged at the upper end of an external side guide seat of a corrugated carton gluing machine, and the eccentric cam is arranged on the outside of the external side guide seat of the corrugated carton gluing machine. The directional automatic folding device disclosed by the invention replaces the traditional belt continuous rolling and folding, the stressed area of a folded carton is large and equalized in exerted force; the folded carton moves along a preset direction, thus being precisely positioned, and no scissors gap and 'fishtail' phenomenon is generated; and a corrugated carton can have a precise geometric size, thereby meeting the need for large-scale and automatic production of the packaging industry.

Description

technical field [0001] The invention relates to the technical field of corrugated carton bonding machines, in particular to a control device during the folding process of corrugated cartons. Background technique [0002] Folder gluer is a kind of equipment used in carton manufacturing. With the continuous development of the economy, all walks of life in the society need to use carton packaging, especially the increasing demand for corrugated cartons. Many companies have used assembly line operations, so the geometric dimension accuracy requirements of carton bonding It is also getting higher and higher. In some industries, such as tobacco and pharmaceutical industries, due to their high degree of mechanization, there must be almost no difference in the size of cartons, otherwise it will affect the assembly line operation and greatly reduce efficiency. The folding and gluing of corrugated boxes requires the cardboard in a state of 180 degrees to be folded to 90 degrees, and ...

AI Technical Summary

Problems solved by technology

As long as the cartons are folded by belt continuous rolling and pinching, the difference in expansion and scissors of the bonding seam cannot be effectively controlled. For the production of small error and high-precision cartons, it can only be completed by manual gluing, which is labor-intensive. , the staff is very hard, and the cost is high, the production efficiency is low, and it cannot meet the large-scale and automated production needs of the packaging industry
