A kind of corrugated corrugated base paper mechanical rolling method

Abstract

The invention discloses a corrugated base paper mechanical rolling method. The upper layer of corrugated base paper and the middle layer of corrugated base paper are rolled into a corrugated shape by a rolling device and then glued, and the upper layer of corrugated base paper, the middle layer of corrugated base paper The base paper and the bottom corrugated base paper transported by the transmission roller are dried and shaped. The rolling device includes two sets of corrugated rolls. The teeth of the lower corrugated roll are provided with grooves. It is pressed into a corrugated shape; a gluing device is arranged on one side of the rolling device; the gluing device applies glue to the groove. The method of the present invention sets grooves on the teeth of the corrugating roller, which is different from the existing method of directly extruding the base paper through the teeth of the corrugating rollers; it is formed by reverse extrusion through the grooves, and the glue is directly applied to the grooves by the gluing device. It makes the valleys and peaks of the formed corrugated base paper stick with glue, and it can be formed at one time, without the need for a clearer to clean the corrugated rollers, reducing mechanical loss and improving production efficiency.

Description

technical field [0001] The invention particularly relates to a method for mechanical rolling of corrugated base paper. Background technique [0002] At present, the production of corrugated cardboard is to preheat and glue each base paper, then dry and cut it, and stack it after cutting. The heating and bonding effect of the base paper directly affects the quality of the cardboard. The roller is heated, so that the temperature of the roller surface cannot be accurately controlled, and it is easy to cause the loss of heat energy. When processing single-sided corrugated paper and double-sided corrugated paper. [0003] The existing mechanical rolling of corrugated base paper utilizes the direct gap between the teeth of the rolls to extrude the base paper and apply glue to the valleys and peaks of the corrugated paper through the glue roller, and then rotate the corrugated roll after clearing the paste through the paste cleaner. It is easy to apply offset power to the directio...

[0002] At present, the production of corrugated cardboard is to preheat and glue each base paper, then dry and cut it, and stack it after cutting.

The roller is heated, so that the temperature of the roller surface cannot be accurately controlled, and it is easy to cause the loss of heat energy.

[0003] The existing mechanical rolling of corrugated base paper utilizes the direct gap between the teeth of the rolls to extrude the base paper and apply glue to the valleys and peaks of the corrugated paper through the glue roller, and then rotate the corrugated roll after clearing the paste through the paste cleaner. It is easy to apply offset power to the rotation direction of the corrugating roller after clearing each time, which increases the loss of gluing and increases the steps of gluing
