Embodiment 1

[0024] A method for manufacturing a corrugated box, comprising the following steps:

[0025] (1) Cardboard impregnation treatment

[0026] Use an automatic paper feeder to continuously feed the corrugated cardboard into the 90°C impregnation tank for 16 seconds, take it out, remove the excess impregnation solution, and then move slowly in the heating chamber to further make the impregnation solution penetrate into the inside of the cardboard and at the same time make the excess impregnation solution The liquid flows away, and then remove the cardboard from the hot air chamber at 120°C, and cool it at room temperature to solidify the impregnating liquid;

[0027] The impregnating solution is made of the following components: flax glue, liquid paraffin, flat plus O and acrylic acid ester. Among them, the weight ratio of flax gum to liquid paraffin is 1:3; the amount of acrylate is 0.2% of the total weight of the soaking liquid; the amount of Pingpinga O is 8% of the total weigh...

Embodiment 2

[0037] A method for manufacturing a corrugated box, comprising the following steps:

[0038] (1) Cardboard impregnation treatment

[0039] Use an automatic paper feeder to continuously feed corrugated cardboard into an 80°C impregnation tank for 20 seconds, take it out, remove excess impregnation liquid, and then move slowly in the heating chamber to further penetrate the impregnation liquid into the interior of the cardboard and at the same time make excess impregnation The liquid flows away, and then remove the cardboard from the hot air chamber at 110°C, and cool it at room temperature to solidify the impregnating liquid;

[0040] The impregnating solution is made of the following components: flax glue, liquid paraffin, flat plus O and acrylic acid ester. Among them, the weight ratio of flax gum to liquid paraffin is 1:4, the amount of acrylate is 0.3% of the total weight of the soaking solution; the amount of Pingpinga O is 7% of the total weight of the soaking liquid.

Embodiment 3

[0050] A method for manufacturing a corrugated box, comprising the following steps:

[0051] (1) Cardboard impregnation treatment

[0052] Use an automatic paper feeder to continuously feed corrugated cardboard into a 100°C impregnation tank for 15 seconds, take it out, remove the excess impregnation solution, and then move slowly in the heating chamber to further allow the impregnation solution to penetrate into the cardboard and at the same time make the excess impregnation solution The liquid flows away, and then remove the cardboard from the hot air chamber at 130°C, and cool it at room temperature to solidify the impregnating liquid;

[0053] The impregnating solution is made of the following components: flax glue, liquid paraffin, flat plus O and acrylic acid ester. Among them, the weight ratio of flax gum to liquid paraffin is 1:3, the amount of acrylate is 0.2% of the total weight of the soaking liquid; the amount of Pingpinga O is 10% of the total weight of the soaki...

Abstract

The invention belongs to the technical field of corrugated paper, and particularly relates to a manufacturing method of a corrugated carton; the method includes the following steps: (1) paperboard dipping treatment: continuously feeding corrugated paperboards into a dipping tank at the temperature of 80-100 DEG C by the aid of an automatic paper feeder, taking out the corrugated paperboards, removing excessive dipping liquid, slowly moving the corrugated paperboards in a hot drying chamber to further allow the dipping liquid to permeate into the paperboards; and meanwhile, enabling redundant impregnation liquid to flow away, then moving the paperboards out of a hot air chamber and cooling at the room temperature, and solidifying the dipping liquid; and (2) carton manufacturing: carrying out die cutting, indentation, slotting and angle opening processing on the paperboards in the step (1) to manufacture corrugated carton blanks, and forming the corrugated carton after the carton blanksare connected. The obtained corrugated carton has good water resistance and fresh-keeping performance and high compressive strength, and is suitable for storage and transportation of various commodities such as seafood and fruits.

Description

technical field [0001] The invention belongs to the technical field of corrugated paper, and in particular relates to a manufacturing method of a corrugated paper box. Background technique [0002] Corrugated cardboard is die-cut, creasing, nailed or glued to make corrugated boxes. Corrugated carton is the most widely used packaging product, and its consumption has always been the first among all kinds of packaging products. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers due to their superior performance and good processing performance, and have become the main force of transportation packaging. In addition to protecting the goods and facilitating storage and transportation, it also plays the role of beautifying and promoting the goods. Corrugated boxes are green and environmentally friendly products, which are conducive to environmental protection and are conducive to loading, unloading and...
