Introduction
For newcomers to the industry, it is crucial to understand the role and working principle of the corrugator. A deep understanding of the working principle can help to make suggestions for improvement and promote technological innovation. Based on the working principle, new types of corrugated board can be developed to meet market demand.In this guide, we will explain what the corrugator machine is, how it works, and why it plays such an important role in the packaging industry.
What is a corrugator?
The corrugator machine is a large industrial machine used to produce corrugated board, mainly used to make packaging materials. The actual performance of a corrugated box depends on three factors: the properties of the core paper and paperboard and the structure of the box itself. The process involves combining three, five or seven sheets of paper together to form a single-layer, double-layer or triple-layer board. The corrugated board production line consists of two relatively independent process sections: wet-end equipment and dry-end equipment. The wet-end equipment mainly includes base paper support racks, automatic paper splicers, preheating machines, single-facer, paper feed bridges, glue coating machines, etc.
Types of Corrugator Machines
There are various types of corrugated machines, which can meet packaging production of different scales and needs according to different uses.
1.Single-sided corrugated machine: produces single-sided corrugated cardboard, suitable for simple packaging needs.
2.Double-sided corrugated machine: produces double-sided corrugated cardboard, suitable for complex packaging needs.
3.Multi-layer corrugated machine: produces multi-layer corrugated cardboard, suitable for high-strength packaging needs.
How Corrugator Machines Contribute to the Packaging Industry
Contribution of corrugated paperboard to the packaging industry
- Corrugated paperboard is made of renewable resources (wood), can be recycled and reused many times, reduces resource waste, and has significant environmental value.
- The corrugated paperboard industry has driven the development of many related industries such as papermaking, printing, packaging, and logistics.
- Corrugated paperboard has high compressive strength and good elasticity, which can meet the needs of contemporary e-commerce for efficient and low-cost packaging.
How does a corrugator work?
The working principle of the corrugator is to process the base paper into corrugated board through preheating, forming, gluing, drying, cooling, slitting and other processes.
- Pre-treatment of base paper
Base paper roll: Corrugated board is usually composed of face paper, core paper, and noodle paper. After these paper rolls are placed in the electric or hydraulic support of the corrugator production line, they are heated and softened by the preheater to form board, which is convenient for the next step.
- Corrugated forming
Corrugated roller: The base paper is bonded to the face paper by the single-sided machine to form a single-sided corrugated board
- Gluing
Gluing device: Through the gluing machine, glue is applied to the formed corrugated core paper and bonded to the face paper.
- Drying, cooling and shaping
Drying: The bonded board is dried by the double-sided machine to accelerate the drying of the glue and enhance the bonding strength. After the cooling function of the double-sided machine, the board is cooled by the cooling roller to stabilize the shape. Fix the shape for subsequent processing.
- Cutting
Vertical and horizontal cutting: The processed corrugated cardboard is cut vertically and horizontally on the cutting machine of the production line according to different needs, which further facilitates the smooth progress of the next process.
- Stacking
The stacking part of the corrugated cardboard production line helps to store the cut cardboard neatly, which is convenient for transportation or the next processing.
Summary
Corrugated paperboard is a commonly used packaging material that can be used to package various electronic products, food, clothing and other items. It can effectively protect items from damage and plays a vital role in the modern packaging industry. It not only meets the needs of product protection and transportation, but also receives more and more attention and support for its environmentally friendly characteristics.
