Corrugated paper machine with spiral oblique-tooth-shaped corrugated rollers

Abstract

The invention discloses a corrugated paper machine with spiral oblique-tooth-shaped corrugated rollers. The corrugated paper machine comprises a rack, wherein a corrugated roller set is arranged inside the rack, and adjusting grooves formed in pairs are formed in the upper side surface of the rack; hydraulic adjusting mechanisms are arranged in the adjusting grooves, and the hydraulic adjusting mechanisms are arranged on the two sides of the corrugated roller set; and the rack is provided with a gluing mechanism making contact with the corrugated roller set, a negative pressure mechanism is arranged on one side of the rack, and a preheating mechanism is arranged on one side of the negative pressure mechanism. The corrugated paper machine has the beneficial effects that conventional straight-tooth-shaped corrugated rollers are changed into spiral oblique-tooth-shaped corrugated rollers so that the spiral oblique-tooth-shaped corrugated rollers can be used for completing the manufacturing of obliquely-corrugated paper; a paper box made of obliquely-corrugated paper avoids the problems that due to straightly-corrugated paper, corrugation exposure and a paper box with a washboard shapetend to occur; and meanwhile, a triangular stress structure can be formed by the side corrugated edges of the obliquely-corrugated paper and the paper box, so that the bearing stability of the paperbox is increased, and the problem of groove folding does not tend to occur.

Description

technical field [0001] The invention relates to a corrugated paper machine, in particular to a corrugated paper machine with spiral helical corrugated rollers. Background technique [0002] At present, in the corrugating unit in the corrugated cardboard production line, the corrugating rollers are all straight-toothed. The corrugated cardboard and the side of the cardboard in the produced corrugated cardboard are parallel, and the direction of the corrugated cardboard is in the form of parallel lines. The corrugated cardboard or carton made It is easy to appear flute and washboard shape, especially when the sandwich paper is used in the five-layer cardboard to reduce the total weight, the thickness of the cardboard becomes smaller, and it is easy to fold grooves, which seriously affects the strength and flatness of the cardboard, and affects the subsequent adjustment and printing. . Contents of the invention [0003] The object of the present invention is to solve the abo...

Problems solved by technology

[0002] At present, in the corrugating unit in the corrugated cardboard production line, the corrugating rollers are all straight-toothed. The corrugated cardboard and the side of the cardboard in the produced corrugated cardboard are parallel, and the direction of the corrugated board is in the form of parallel lines. The corrugated cardboard or carton made It is easy to appear flute and washboard shape, especially when the sandwich paper is used to reduce the total weight of the five-layer cardboard, the thickness of the cardboard becomes smaller, and it is easy to fold grooves, which seriously affects the strength and flatness of the cardboard, and affects the subsequent adjustment and printing.
