Ear folding mechanism of pasting box machine

Abstract

The invention relates to a paper box forming machine, in particular to a mechanism for folding wide edges of a sample box board. The ear folding mechanism comprises a forming inner die and a lifting device of the forming inner die, and is characterized in that gear boards are respectviely arranged on two sides of the forming inner die; swing blocks are arranged at the outer sides of the gear boards, and the upper ends of the swing blocks are hinged onto the outer sides of the ger boards; infolding fixed blocks are arranged at the right sides of the gear boards, and 7-shaped infolding claws are hinged on the infolding fixed blocks; elastic parts are arranged between the infolding claws and the infolding fixed blocks or between the infolding claws and the gear boards; and support parts which can be acted on the lower ends of the swing blocks and can enable the swing blocks to cross the left sides of the gear boards are arranged at the tail ends of the infolding claws. The ear folding mechanism of a pasting box machine has the advantages of simple structure, flexible action and convenience in replacement.

Description

technical field [0001] The invention relates to a carton forming machine, in particular to a mechanism for folding ears on the wide side of a sample box board. Background technique [0002] Before the carton (especially the shoe box) is formed, it is a sample box board, which generally includes a long side part, a folded ear part, a wide side part, and some also include a wide side folded inward part. Generally, the folder-gluer can realize the folding of the above-mentioned parts, and finally form the finished carton.
