Intelligent folding production line for lining box

Abstract

The invention discloses an intelligent folding production line for a lining box. A folding channel for folding a paperboard is arranged on a rack in a penetrating manner; a paper feeding device, a multi-channel folding forming machine, a barrel box folding mechanical arm, a three-face conveying device, an end edge inner folding device, a front end wall folding machine, a steering conveyor, an endedge inner folding device and a rear end wall folding machine are sequentially arranged along the folding channel from front to back; the multi-channel folding forming machine comprises a first folding guide rail, a second folding guide rail, a third folding guide rail and a fourth folding guide rail which are symmetrically arranged along the left side and the right side of the center line of thefolding channel; the barrel box folding mechanical arm comprises a holding supporting plate and a holding rotary disc which are hinged to the rack; the end edge inner folding device comprises an end edge inner folding claw; and the front end wall folding machine comprises an end folding lower conveying belt and an outer end lifting folding device. According to the intelligent folding production line for the lining box, folding forming of the lining box of a complex structure and a barrel pipe box wall can be conducted, the folding forming quality is good, and the production efficiency is high.

Description

technical field [0001] The invention relates to a carton box folding and forming equipment, in particular to a folding and forming machine for a paper inner liner box in a packing box (box). Background technique [0002] Packaging boxes (boxes) not only have the functions of containing, storing and protecting products, but also have the functions of environmental protection and beautification. They are widely used in the packaging of food, medicine, express delivery, wine and various light industrial products; The liner box has a good cushioning and shock resistance effect, can effectively limit the buffer, prevent bumps and sloshing, and play an excellent role in protecting the packaged products. [0003] The traditional packing box liner buffer structure mostly uses chemical materials such as EPE, EPP, EVA, PS, etc., which consumes more resources in the production process and is difficult to recycle, especially the discarded liner box is difficult to degrade, which is harm...

AI Technical Summary

Problems solved by technology

The production of paper-lined boxes with corresponding equipment such as box folding and gluing machines can effectively reduce labor costs, improve production efficiency and product authenticity rate, but the current box gluing equipment has a single function and insufficient process flexibility and scalability. It is often only possible to fold and form a single-layer box wall and a simple crease box body, but it is impossible to manufacture and process the inner box with a tubular box wall, and it is difficult to adapt to the increasingly complex and changeable box structure requirements; the traditional Folding box forming can only carry out plane folding and conveying of the paper substrate, neither the side wall folding operation of the barrel cavity structure nor the end wall folding operation of the barrel cavity structure; however, due to the inner The liner box can play a better role in buffering and protecting the product, making this new structure of paper liner box gradually replace the single-layer box wall liner box products

Therefore, the existing manufacturing process and production equipment of the inner box have become the restrictive factors for the development of the inner box to the direction of high cushioning performance and high protection.
