Corrugated carton production process and automatic production line thereof

Abstract

The invention relates to the technical field of printing and packaging, in particular to a corrugated carton production process and an automatic production line thereof. The corrugated carton production process includes the steps of paper splitting and line pressing, picture and text printing, mold pressing, connecting, bundling and stacking. The automatic production line comprises a paper splitting and line pressing machine, a slotting printing machine, a molding press, a waste paper removing device, a carton bonding machine, a packaging machine and a stacking machine, wherein the paper splitting and line pressing machine, the slotting printing machine, the molding press, the waste paper removing device, the carton bonding machine, the packaging machine and the stacking machine are sequentially connected through a conveying mechanism. The slotting printing machine is provided with an ultraviolet drying device, and a controller of the automatic production line is used for controlling communication and speed synchronization among all the single devices. According to the corrugated carton production process and the automatic production line thereof, the structure is reasonable, automatic production is achieved, production efficiency for existing corrugated cartons is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of printing and packaging, in particular to a corrugated box production process and an automatic production line thereof. Background technique [0002] Corrugated cartons are the most widely used packaging products. Because of their good physical and mechanical properties, adaptability to decoration and printing, economical practicability and environmental protection, the amount of corrugated boxes has always been the first among all kinds of packaging products. At present, the main process steps of corrugated cartons have basically realized mechanized production. However, there is a lack of coordination between various processes and equipment, and some links require manual assistance. The obstacles to continuous production of corrugated cartons are mainly: In the production process A large amount of waste paper will be produced, especially the molding machine of the cardboard production line, the die-cuttin...

AI Technical Summary

Problems solved by technology

At present, the main process steps of corrugated cartons have basically realized mechanized production. However, there is a lack of coordination between various processes and equipment, and some links require manual assistance. The obstacles to continuous production of corrugated cartons are mainly: In the production process A large amount of waste paper will be produced, especially the molding machine of the cardboard production line, the die-cutting machine and slotting machine of the carton linkage production line, etc. The waste paper produced has various shapes and is in a state of fluffy and disorderly stacking, which must be cleaned continuously Otherwise, it will not only block the workshop, but also cause equipment damage and affect production in severe cases

The existing cardboard production line and carton linkage production line each have an independent waste paper cleaning system, which not only costs a lot but also occupies a large area

In addition, the way of conveying corrugated cardboard to equipment such as printing machines or molding machines is mainly manual, and one or two people need to transfer the stacks (that is, several cardboards stacked to a certain height) to the molding machine or printing machine in batches. On the paper feeding table, personnel are required to control the whole process of paper feeding, the degree of automation is low, and the labor intensity is high
