Single-corrugated two-layer paperboard production equipment

Abstract

The invention relates to single-corrugated two-layer paperboard production equipment. The single-corrugated two-layer paperboard production equipment comprises a first paper holder, a second paper holder, a corrugating machine, a cutting device, a packing molding device, a conveying device, a first preheating roller, a second preheating roller, a heat supply unit and an atomizing and spraying unit, wherein the first paper holder and the second paper holder are used for carrying two kinds of paper; the corrugating machine is located between the first paper holder and the second paper holder; the conveying device connects an outlet of the corrugating machine with an inlet of the cutting device and facilitates conveying of paperboards; the first preheating roller is arranged between the first paper holder and the corrugating machine; the second preheating roller is arranged between the second paper holder and the corrugating machine; the heat supply unit is used for supplying heat to the first preheating roller and the second preheating roller; the atomizing and spraying unit gets close to an inlet of the cutting device; and the particle diameter of water spray particles produced by the atomizing and spraying unit and sprayed to the surfaces of paperboards is 15-25 microns. On one hand, the single-corrugated two-layer paperboard production equipment can effectively reduce wrinkles of molded paperboards and guarantee the flatness of the paperboards, and on the other hand, the single-corrugated two-layer paperboard production equipment can effectively enhance the automatic adhesive capacity of double-layer paperboards and improve the quality, and is simple in structure, convenient to implement and low in cost.

Description

technical field [0001] The invention relates to a production equipment of single-corrugated two-layer cardboard. Background technique [0002] The production equipment of single-corrugated two-layer cardboard mainly includes a paper frame for placing two kinds of paper rolls, a corrugating machine for gluing the two kinds of paper into shape, and a cutting machine connected with the discharge port of the corrugating machine through a transmission mechanism. device, wherein the cutting device cuts the formed cardboard into the required size. [0003] However, in actual operation, the above-mentioned production equipment has the following defects: [0004] 1. The formed cardboard is prone to wrinkle deformation (warping), which makes it difficult for the flatness of the cardboard to meet customer needs; [0005] 2. Since the paper rolls are exposed to the outside for a long time, it is easy to absorb moisture in the air. If the moisture is not removed, it will inevitably lea...

Problems solved by technology

[0004] 1. The formed cardboard is prone to wrinkle deformation (warping), which makes it difficult for the flatness of the cardboard to meet customer needs;

[0005] 2. Since the paper rolls are exposed to the outside for a long time, it is easy to absorb moisture in the air. If the moisture is not removed, it will inevitably lead to poor bonding stability and directly affect the quality of the formed cardboard
