The production of cardboard boxes has evolved from a single machine, purely manual operation. Up to now, there are various production processes. The corrugated sheets are pressed by a single facer machine, then laminated with a manual laminating machine, and finally the corrugated cardboard is made into cardboard boxes using a single printing machine, a slotting and corner-cutting machine, and a box-nailing machine.
Combining multiple individual machines to form a line, which is now referred to as an automatic corrugated board production line, this line can be classified into A-type line (with smaller diameters for the corrugating rollers and preheating rollers), B-type line (with larger diameters for the corrugating rollers and preheating rollers), and Z-type line (where the corrugating rollers of different types can be quickly replaced). Additionally, there are low-speed lines, medium-speed lines, and high-speed lines.
Use a single facer machine to press the corrugated board, use a lithographic press to print the colored surface paper, combine the surface paper with the single-sided corrugated board using a laminating machine, then cut it into shape with a die-cutting machine, and use a gluing machine to bond the corrugated board to make a colored corrugated carton.
The corrugated cardboard production line mainly consists of the following individual machines and systems:
- Cordless roll paper holder
- Paper preheater
- Single facer machine
- Conveyor bridge
- Multiple preheaters
- Double facer machine
- Electric control system
- Steam system
- Thin blade slitter scorer machine
- NC cutter
- Stacker
- Air system
- Waste paper recycling system
