Problems solved by technology

[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

Embodiment 1

[0024] image 3 The solid arrows in the figure indicate the spraying direction of the nozzle 4, and the hollow arrows indicate the corrugated corrugated direction.

[0025] Such as figure 1 , figure 2 with Figure 5 As shown, the preferred embodiment of the pressure-line forming explosion-proof paper softening device of the present invention includes four nozzles 4, one transverse guide rail 1, four transverse moving seats 2, four drivers, and one longitudinal guide for adjusting the longitudinal position of the transverse guide rail 1. Mobile device, steam supply device 7 and control box 99. The driver is a motor 3, and the four laterally moving seats 2 are slidably arranged on the transverse guide rail 1, and each nozzle 4 is fixed to a transversely moving seat 2, and the motor 3 is used to drive the laterally moving seat 2 on the transverse guide rail 1. The upward movement makes the nozzle 4 move to the working position, the transverse guide rail 1 is fixed on the lon...

Embodiment 2

[0033] Such as Image 6 As shown, the difference between this embodiment and Embodiment 1 is that there are four horizontal guide rails and the horizontal guide rails are lead screws 81, and there are four longitudinal moving devices, and the lead screw 81, the motor 3, and the The seat 2 corresponds to the longitudinal moving device one by one, and the remaining parts are the same as in Embodiment 1.

[0034] The motor 3 is fixed on the transverse rail seat 13 , the output shaft of the motor 3 is connected to the lead screw 81 , and the transverse movement seat 2 is screwed on the lead screw 81 .

Embodiment 3

[0036] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 2 is that the driver is a cylinder 91, the transverse guide rail is a piston rod 92 of the cylinder 91, and the rest are the same as Embodiment 2. In other embodiments, the gas 91 is also replaced by a hydraulic cylinder.

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.
