Product Description

Product Description

3/5/7Ply corrugated cardboard production line

The corrugated cardboard production line is a set of core equipment that processes raw paper (surface paper, core paper, and backing paper) through a series of continuous processes, including corrugating, gluing, cutting, and drying, to ultimately produce corrugated cardboard. It is considered the "heart" of the packaging industry. The core components and processes of this production line can be divided into three parts:

1. Wet section: The core of this process is corrugation. Corrugating rollers are used to press the core paper into the desired corrugation pattern (such as A, B, C, or E corrugations). Then, a gluing machine applies adhesive to the top of the corrugations, and finally, the paper is bonded with the surface and backing papers on a heat press to form multi-layer corrugated cardboard.

2. Dry section: This section is responsible for drying and setting the shape of the cardboard. The wet cardboard is conveyed onto a drying channel, where high-temperature hot air is used to remove moisture and cure the adhesive, ensuring the cardboard's hardness and flatness. After that, the cardboard is cut longitudinally and transversely to achieve standard sizes.

3. Auxiliary systems: These include raw paper racks for storing and transporting the raw paper, a tension control system to ensure smooth and accurate transportation of the raw paper, a waste recycling system for collecting cut-off scraps, and an intelligent control system that monitors parameters such as production speed, temperature, and bonding accuracy in real time.

The differences between various production lines mainly lie in their production capacity (ranging from 100 to 400 meters per hour), the number of layers that can be produced (3 to 7 layers), and the degree of automation (manual, semi-automatic, or fully automatic). These systems can be flexibly selected based on the scale of the company's orders and the specific product requirements.
