Cardboard Making Line

1. product introduction

In the modern packaging industry, corrugated cardboard is highly valued for its unique physical properties and a wide range of applications. With the rapid development of e-commerce, food, home appliances and other industries, the demand for corrugated cardboard has increased year by year, which has promoted the technical progress of corrugated cardboard production line and the improvement of equipment automation level.

2. The definition and characteristics of corrugated cardboard

Corrugated board is a composite material formed by bonding corrugated paper and face paper. Its structure is generally composed of one or more layers of corrugated paper (that is, corrugated core paper) and two layers of paper. Corrugated cardboard mainly has the following characteristics:

1. Lightness: Compared with other materials, corrugated cardboard is light in weight and easy to handle and transport.

2. High strength: Corrugated cardboard has good compressive strength and seismic performance, which can effectively protect internal products.

3. Environmental protection: Corrugated cardboard is a renewable material, in line with the development trend of modern green packaging.

3. The working principle of corrugated cardboard production line

Corrugated cardboard production line is an automatic equipment, mainly through the following steps to complete the production process of cardboard:

1. Raw material preparation: The production line first places the paper roll (usually the paper web) on the paper roll rack, and transmits the paper to the next process through the automatic feeding device.

2. Corrugated forming: Through the corrugated forming machine, the paper is processed into corrugated shape after heating and pressure.

3. Gluing and bonding: Glue is applied on the surface of corrugated paper, and then the corrugated paper is combined with the face paper to form a strong corrugated board.

4. Drying and cooling: The bonded corrugated cardboard will be kept at a certain temperature in the dryer to ensure that the glue is fully cured.

5. Cutting and forming: Use the cutting machine to cut the large cardboard into the specifications required by customers to ensure the accurate size.

6. Stacking and packaging: Finally, the finished cardboard is automatically stacked by the stacker, and packaged for easy transportation and storage.

4. The main components of corrugated cardboard production line

Corrugated cardboard production line is generally composed of the following main parts:

1. Paper roll holder: used to support and fix the raw material roll to ensure the smooth supply of paper.

2. Corrugated forming machine: The paper is processed into a corrugated shape, which usually contains multiple forming rollers and heating devices.

3. Gluing machine: It is responsible for gluing between corrugated paper and face paper to ensure a good bond between the two.

4. Dryer: Through hot air or infrared, the glue is quickly dried to improve production efficiency.

5. Cutting machine: The use of laser or cutting tool to accurately cut the cardboard to ensure that the size of each finished product is consistent.

6. Stacker: automatically stack the cardboard after cutting, reducing the labor intensity of manual handling.

7. Control system: Modern production lines are usually equipped with PLC (Programmable logic controller) systems to achieve automatic control and data monitoring of equipment.

5. Technical features and advantages

Technical features of corrugated board production line include:

1. High degree of automation: The high degree of automation of the production line can realize the coordination between the equipment, reduce manual intervention, and improve production efficiency.

2. Flexibility: Modern production line design takes into account changes in market demand, and different specifications and types of cardboard can be customized according to customer orders.

3. Intelligent: equipped with advanced control system to achieve real-time monitoring, data acquisition and fault diagnosis, improve the intelligent level of production.

4. Energy saving and environmental protection: Many new production lines use energy-saving technology to reduce energy consumption, in line with the concept of green production.

6. FAQ

What is corrugated board production line?

Corrugated board production line is a special equipment for the production of corrugated board, including wet end equipment, cadre equipment and production management system. The production line processes web base paper into high-quality corrugated board through a series of processes, which is widely used in the packaging industry.

What are the main components of corrugated board production line?

Corrugated board production line mainly consists of the following equipment:

- Base paper holder

- Automatic paper feeder

- Preheat the preheater

- Single side corrugating machine

- Double-sided machine

- Slitting and indentation machine

- Crosscutting machine

- Stacker

What is the working principle of corrugated board production line?

The working principle of the corrugated board production line is to make the base paper into single-sided corrugated paper by heating and pressurizing, and then two layers of single-sided corrugated paper are bonded together to form double-sided corrugated paper. After the longitudinal indentation and cross cutting treatment, finally get the corrugated board that meets the requirements.

How efficient is the corrugated board production line?

Corrugated board production lines have efficient production capacity and can usually produce thousands of square meters of corrugated board per hour. The efficiency depends on the model and configuration of the device.

How automated is the corrugated board production line?

Modern corrugated cardboard production lines are usually equipped with advanced automated control systems to achieve the whole process of automatic control from raw material input to finished product output, reduce manual operation, and improve production efficiency and product quality.

What is the environmental performance of corrugated board production line?

The corrugated board production line uses environmentally friendly materials and low noise design to reduce the impact on the environment. At the same time, the waste generated in the production process can also be recycled to further reduce environmental pollution.
