Paperboard folding device

Abstract

The invention relates to a paperboard folding device. The paperboard folding device comprises folding wheel cutters, wherein the folding wheel cutters comprise multiple groups of upper wheel cutters and lower wheel cutters, the upper wheel cutters and the lower wheel cutters are separately arranged at the upper and lower positions of outlets of paperboard cutting devices, and the upper wheel cutters and the lower wheel cutters are arranged on respective lifting racks in a rotating manner; lifting mechanisms drive the upper wheel cutters and the lower wheel cutters to move towards each other or far from each other; and dragging mechanisms are arranged at the feeding opening and discharging opening positions of the upper wheel cutters and the lower wheel cutters, and the dragging mechanisms are used for dragging support plates to move along folding openings formed between the upper wheel cutters and the lower wheel cutters. When paperboards cut by the paperboard cutting devices are guided into the folding device, the lifting mechanisms are started, and the upper wheel cutters and the lower wheel cutters are driven to move towards each other; and the dragging mechanisms are started, the paperboards are pulled or pushed to pass the folding openings formed between the upper wheel cutters and the lower wheel cutters, and the surface folding operation of the paperboards can be realized. The folding reliability of the paperboards is ensured.

Description

technical field [0001] The invention relates to the technical field of packaging boxes, in particular to a cardboard crease device. Background technique [0002] In the actual processing of packaging boxes, corrugated paper or coated paper is generally used as raw materials for production. In the production process, it is generally exported individually, and a single cardboard is guided from the guide belt, and passes through the film covering device, the opening device, and the crease device, and finally forms the blank of the packaging box, which can then be processed manually or mechanically. The packaging box is subjected to the back cover operation in a unique way, and finally a complete packaging box that can accommodate items is formed. [0003] There are many crease machines for cardboard on the market. When the crease machine performs the crease operation on the cardboard, it is required that the crease machine can quickly and effectively perform the crease operati...

Problems solved by technology

[0003] There are many crease machines for cardboard on the market. When the crease machine performs the crease operation on the cardboard, it is required that the crease machine can quickly and effectively perform the crease operation on the cardboard, so as to avoid the reset of the cardboard after crease, so that The problem of poor crease effect is that the cardboard crease equipment in the prior art has low crease efficiency when performing the crease operation on the cardboard. When the number of creases on the cardboard is large, the crease cannot be straight degree, which leads to poor crease effect of cardboard
