Paper explosion-preventing softening device for line pressing and molding and softening method for pressed-line crease positions of paperboards

Abstract

The invention discloses a paper explosion-preventing softening device for line pressing and molding and a softening method for pressed-line crease positions of paperboards. The paper explosion-preventing softening device comprises at least one nozzle, at least one transverse guide rail, transverse moving seats as many as the nozzles and drivers as many as the nozzles; the transverse moving seats are arranged on the transverse guide rails in a sliding manner; each nozzle is fixed with one transverse moving seat; the drivers are used for driving the transverse moving seats to move on the transverse guide rails to working positions. The paper explosion-preventing softening device for line pressing and molding is capable of softening surface paper, core paper, lining paper and corrugated paper at the pressed-line crease positions of the paperboards by use of high-temperature steam; the method is capable of preventing paper breaking of the paperboards during line pressing or molding.

Description

technical field [0001] The invention relates to the technical field of carton creasing crease position softening, in particular to a crimping forming explosion-proof paper softening device and a method for softening the creasing crease position of a cardboard. Background technique [0002] The current corrugated cardboard or carton production enterprise cartons are prone to paper bursting during the crimping or forming process. The main reasons for the paper bursting phenomenon are: 1. The cardboard material is relatively poor (the fiber content of the base paper is low and the fiber is short), so that The bursting value of the cardboard itself is very low; 2. When the cardboard passes through the press line of the printing machine, because the moisture content of the cardboard itself is low and dry, the toughness of the cardboard is reduced, and the bursting resistance is reduced, which will cause the phenomenon of paper bursting in the press line forming of the cardboard ,...

[0002] The current corrugated cardboard or carton production enterprise cartons are prone to paper bursting during the crimping or forming process. The main reasons for the paper bursting phenomenon are: 1. The cardboard material is relatively poor (the fiber content of the base paper is low and the fiber is short), so that The bursting value of the cardboard itself is very low; 2. When the cardboard passes through the press line of the printing machine, because the moisture content of the cardboard itself is low and dry, the toughness of the cardboard is reduced, and the bursting resistance is reduced, which will cause the phenomenon of paper bursting in the press line forming of the cardboard , the situation is even more serious in the dry season

The quality and appearance of the product are seriously affected after the phenomenon of paper bursting. In order to meet the customer's product packaging requirements, the supplier can only use better material base paper, which increases the cost; in addition, when the strength of the cardboard line is high, Especially when the position of the creasing crease is just at the tip of the corrugated corrugation, the position of the creasing crease will deviate from the set position during the creasing process, which will cause errors in the carton forming size
