Packaging paper box edge-folding device and machining method thereof

Abstract

The invention provides a packaging paper box edge-folding device and a machining method thereof. The packaging paper box edge-folding device comprises an air cylinder, a bracket and supporting frames.The bracket is fixedly connected to the air cylinder, U-shaped plates are symmetrically arranged at the tops of the two ends of the bracket, the supporting frames are symmetrically arranged on the outer side of the bracket, and hydraulic cylinders are arranged on the inner sides of the supporting frames; hydraulic stay bars are connected to the hydraulic cylinders, the hydraulic stay bars are connected with pressing plates, a baffle is arranged over the bracket, and a guide rail is arranged at the lower end of the baffle; and two push plates matched with the guide rail are arranged on the guide rail, pressure sensors are arranged at the bottoms of the push plates, the baffle is connected with a servo motor through a connecting rod, and an electronic control device is arranged on one sideof the servo motor. The packaging paper box edge-folding device and the machining method thereof have the beneficial effects that the two U-shaped plates can simultaneously conduct folding on the fourbottom edges of the paper box, a plurality of processes are omitted, meanwhile the push plates in the paper box can achieve the supporting and pushing effects, the packaging paper box where a productis placed and cannot be prepared due to an error is avoided, the packaging paper box edge-folding device can operate normally, and the production efficiency of paper box processing is improved.

Description

technical field [0001] The invention belongs to the technical field of packaging equipment, and in particular relates to a packaging carton folding device and a processing method thereof. Background technique [0002] Corrugated boxes are rigid paper containers made of corrugated cardboard. With its superior performance and good processing performance, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers and become the main force of transportation packaging. In addition to protecting the goods and facilitating storage and transportation, it also plays the role of beautifying and promoting the goods. Corrugated boxes are green and environmentally friendly products, which are conducive to environmental protection and are conducive to loading, unloading and transportation. [0003] The size design of the carton is a very important task in the structural design of the corrugated carton. A qualified carton product must have protec...

AI Technical Summary

Problems solved by technology

In carton packaging molding, the folding of cardboard requires multiple steps to be folded, and finally the top edge of the carton is sealed. This method of folding cardboard is cumbersome, and the folding device takes up a lot of space, and the cost of production and processing is also increased. ;When putting the product into the carton, due to the error between the size of the product and the inner size of the carton, the product cannot be smoothly placed in the carton or will fall outside the carton, resulting in the malfunction of the folding device and affecting the production efficiency
