1. 5-layer corrugated board production line product introduction
The 5-layer corrugated board production line is a commonly used and efficient production equipment in the packaging industry, which is mainly used for the production of high-strength and high-toughness corrugated board. This production line integrates two parts of wet end equipment and cadre equipment. Through a series of precision processes, the web base paper is processed into corrugated board with specific corrugated shapes and specifications. The 5-layer corrugated board production line is favored by many packaging companies because of its superior performance and wide application fields.
2. Product composition
The 5-layer corrugated board production line is mainly composed of wet end equipment and cadre equipment, including the following key components:
Wet end equipment:
Base paper holder: As the starting point of the production line, responsible for storing and conveying different specifications of web base paper.
Automatic paper feeder: to ensure that the base paper in the conveying process seamless connection, improve production efficiency.
Preheat preheater: preheat the base paper to improve the softness and processability of the paper.
Single-side corrugating machine: Press the base paper into corrugated core paper with a specific shape through the close cooperation of the upper and lower corrugating rollers, and apply glue.
Double-sided machine: Glue the corrugated core paper and the face paper to form double-sided corrugated board.
Cadre equipment:
Rotary cutting machine: according to the requirements of the order to precisely cut the corrugated board.
Longitudinal cutting and indentation machine: indentation of cardboard, convenient for subsequent folding and forming.
Horizontal cutting machine: transverse cutting to ensure that the cardboard specifications meet the standard.
Stacker: Stack the cut corrugated cardboard neatly for easy transportation and storage.
3. How it works
The working principle of the 5-layer corrugated board production line is based on the mechanical principles in physics and chemical adhesion. The specific process is as follows:
Base paper preheating: the base paper is preheated by preheating preheater to improve the softness and plasticity of the paper.
Corrugated forming: The preheated base paper enters the single-side corrugating machine, presses the corrugated core paper into a specific shape through the close cooperation of the upper and lower corrugating rollers, and is coated with glue.
Double-sided laminating: The coated corrugated core paper is pasted with the face paper through the double-sided machine to form double-sided corrugated board. At this time, the two sides of the cardboard are respectively composed of face paper and corrugated core paper, which enhances the strength and toughness of the cardboard.
Drying and curing: double-sided corrugated cardboard is heated by the hot plate, so that the glue can cure quickly and ensure the firmness of the cardboard structure.
Cutting and indentation: the dried cardboard goes into the equipment, and is precisely cut and indentation by rotary cutting machine, longitudinal cutting and indentation machine and horizontal cutting machine to form corrugated cardboard that meets the specifications.
Stacking output: the cut corrugated cardboard is stacked neatly by the stacking machine to complete the entire production process.
4. Product features
High production efficiency: 5-layer corrugated board production line adopts intelligent production management system to realize automatic production and control, which greatly improves production efficiency. For example, the single-side corrugator adopts two sets of corrugator roller design, which can realize the rapid replacement of the overall multi-corrugated type, and the roller change time is only 5 minutes, which significantly reduces the labor intensity of the operator.
Excellent quality: The wet end process can give full play to the potential of raw materials, strengthen the strength and stiffness of the cardboard, and improve water resistance and thermal stability. For example, the corrugated roller is made of special alloy steel, precision grinding through heat treatment process and hard chrome plating on the surface to ensure the wear resistance and service life of the corrugated roller.
Environmental protection and energy saving: The production line adopts energy-saving and environmental protection equipment, and the waste materials are recycled and utilized, which greatly reduces the energy consumption and waste discharge in the production process. For example, the production line is equipped with a perfect waste gas treatment system, which effectively reduces harmful gas emissions in the production process.
Affordable: Corrugated paper is a lightweight, high strength, low cost material, so compared with other packaging materials, corrugated paper is more favorable in cost. This helps enterprises to save packaging costs and improve market competitiveness.
5. Scope of application
The 5-layer corrugated board production line is widely used in many fields, mainly including:
Food packaging: used for making food packaging boxes, trays, etc., to ensure the safety and hygiene of food. The moisture and waterproof properties of corrugated cardboard can effectively protect food from the influence of the external environment.
Electronic product packaging: Provides protection for electronic products against damage during transportation and storage. The compression and shock resistance of corrugated cardboard make it an ideal choice for electronic packaging.
Logistics and transportation: used to make corrugated boxes, as the main packaging materials in logistics and transportation. Corrugated boxes are light, strong and easy to stack, which helps to reduce transportation costs and improve logistics efficiency.
Furniture manufacturing: as an auxiliary material in furniture manufacturing, such as partition board, backboard, etc. The strength and toughness of corrugated cardboard can meet the various needs of the furniture manufacturing process.
In addition, with the increasingly prominent advantages of corrugated cardboard in green environmental protection, its application has also begun to extend to other production and processing fields such as food and beverage, tea.
