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...
