company news about What is the corrugated cardboard box machine's operating principle?

In order to create corrugated cardboard boxes, raw materials (like kraft paper) must be processed, formed, and bonded in a series of steps according to the machine's operating principle. Its fundamental principles and workflow are as follows:

1. Corrugated cardboard production
The corrugated cardboard production line completes this initial phase in the creation of cardboard boxes:
Rewinding raw paper: The production line receives corrugated raw paper (core paper) and roll-shaped box board paper (facial paper/inner paper).
Preheating: To eliminate moisture and enhance plasticity, a preheating roller heats the base paper.

The process of corrugated forming involves using two corrugated metal rollers to press the corrugated paper into wavy corrugations, such as A, B, C, etc.
Adhesive coating and bonding: Cover the corrugated board with adhesive (like starch glue), adhere it to the surface paper, and create a single-sided corrugated cardboard (repeat this process if more than one layer is needed).

Drying and shaping: To create a strong corrugated cardboard, the glue is dried using a high-temperature dryer (such as a hot plate or drying channel).
2. Forming and processing cartons
The primary tools for processing the corrugated cardboard into cardboard boxes are die-cutting, printing, slotting, and box nailing/gluing machines:

(1) Slotting and printing
Printing: Patterns and text can be printed on cardboard using a flexographic printing machine and water-based ink.
Slotting: Rotate the blade to create creases (pressure lines) and slots (slotting) on the cardboard box's bottom and lid.
Die cutting (if a box with a specific shape is needed): Use a mold to cut a specific shape.
(2) Adhesive/nail box
Nail box machine: Attach the box body's seams together with metal nails.
The glue box machine, which is more eco-friendly and appropriate for upscale packaging, uses adhesive to join seams.
Important elements and ideas
Corrugated roller: a fundamental component that generates wavy patterns by gear meshing, affecting the strength of cardboard.
glue: typically a starch-based glue, which needs to be applied precisely to avoid delamination.
A drying temperature of 150–180 °C ensures that the adhesive cures quickly and that the cardboard does not deform.

Scenarios for applications
Production with a single machine: Small companies may employ a single machine in phases (e.g., nail box machines, crimping machines).
Linkage manufacturing line: To turn raw paper into boxes all at once, large manufacturers use automated assembly lines.
The corrugated cardboard box machine effectively completes the conversion from raw materials to final products through the aforementioned process, satisfying the requirements of many sectors for packaging shape, strength, and printing.
