Paper box or carton automatic opening and bottom folding method and facility

Abstract

The invention discloses a paper box or carton automatic opening and bottom folding method. The paper box or carton automatic opening and bottom folding method comprises the steps that a paper box or carton which is located in an original state is pushed into a station through a material push mechanism, a front tongue press mechanism tightly presses a front tongue of the paper box or carton, a sideplate folding mechanism pushes side plates of the paper box or carton so that the paper box or carton can be opened, a tensioning mechanism stretches into the paper box or carton so that the paper box or carton can be completely opened and located, a long tongue is folded by a bottom folding device, then a left tongue and a right tongue are folded, finally an upper tongue is folded, the tongue tip of the upper tongue can be inserted into the inner side of the lower tongue, and therefore the automatic bottom folding operation of the paper box or carton is accomplished. The invention further discloses a paper box or carton automatic opening and bottom folding facility. The paper box or carton automatic opening and bottom folding method and facility achieve the folding mechanization, the folding automation and the folding unattended operation of the paper box or carton, the production efficiency is greatly improved, and the manpower is saved. In addition, the bottom of the paper box or carton is buckled together through the upper tongue, the lower tongue, the left tongue and the right tongue of the paper box or carton, and does not need to be additionally pasted by glue.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a carton or carton automatic opening and bottom folding method, and also relates to carton or carton automatic opening and bottom folding equipment. Background technique [0002] Paper boxes and cartons are widely used in product packaging, such as the packaging of medicines, cosmetics, batteries and other items. For the convenience of transportation, common cartons and cartons are folded after being produced by packaging and printing factories, such as figure 1 As shown in the carton, the carton needs to be opened and sealed before the product is packed. The traditional way of folding the bottom of the carton / carton is to fold the left tongue of the carton / carton after the carton / carton is opened. 11 and the right tongue 14, then apply glue, then fold the upper tongue 12 and the lower tongue 13, paste the upper tongue 12 and the lower tongue 13 with the left tongue 11 and the...

AI Technical Summary

Problems solved by technology

Glue and adhesive tape are used in the packaging process at the bottom of the carton. It is necessary to integrate a glue-applying and glue-applying mechanism into the equipment. The structure of the equipment is relatively complicated, and it is not environmentally friendly.

[0003] In fact, the upper tongue 12, lower tongue 13, left tongue 11 and right tongue 14 of the carton itself have a certain strength, and the bottom cover can be completed by folding the bottom to make them intersect and buckle together, but at present, the bottom can only be folded manually. Low folding efficiency and high labor cost
