2. Describes the main components

1) Base paper holder

The base paper holder is the starting part of the production line and is used to carry and transport various sizes of base paper. It usually has an automatic tension control function, which can ensure that the base paper maintains a stable tension during the transportation process to avoid relaxation or breakage. At the same time, the base paper holder can also quickly replace the base paper, improve production efficiency.

2) Single-sided machine

Single-sided machine is one of the core equipment for the production of corrugated cardboard. By heating and pressurizing, the corrugated core paper and the face paper are bonded together to form a single-sided corrugated board. The single-sided machine of the old 7-layer cardboard production line usually uses advanced technology to accurately control the temperature and pressure to ensure the stable quality of the corrugated board. In addition, the single-sided machine also has high-speed production capacity, which can meet the needs of large-scale production.

3) Double-sided machine

The double-sided machine is used to glue two layers of single-sided corrugated cardboard together with one layer of sandwich paper to form seven layers of corrugated cardboard. It also has precise temperature and pressure control to ensure the bonding strength of corrugated cardboard. The design of the double-sided machine is reasonable, the operation is convenient, and the production parameters can be adjusted quickly to adapt to the production of different specifications.

4) Dryer

The role of the dryer is to dry the corrugated cardboard just glued, so that the glue can cure quickly and improve the strength and stability of the cardboard. The dryer of the old 7-layer cardboard production line usually uses an efficient heating method, which can heat up quickly and shorten the drying time. At the same time, the dryer also has a good ventilation system to ensure that the cardboard is evenly heated during the drying process to avoid local overheating or insufficient drying.

5) Slitting machine and crosscutting machine

The slitting machine and the crosscutting machine are respectively used to cut the dried corrugated cardboard lengthwise and crosswise according to the predetermined size. These two devices have high precision and fast cutting speed, which can meet the production needs of different specifications. The operation of the slitting machine and the crosscutting machine is simple, easy to adjust, and the cutting size can be adjusted quickly according to the requirements of customers.

6) Stacker

The stacker is used to stack the cut corrugated cardboard neatly for easy storage and transportation. It has the advantages of high automation, fast stacking speed and neat stacking. The design of the stacker is reasonable and can adapt to the needs of different sizes and weights of corrugated cardboard stacker.

3. Product advantages

1) High cost performance

The old 7-layer cardboard production line is used as second-hand equipment, and the price is relatively low, which can save a lot of investment costs for enterprises. At the same time, after professional maintenance and optimization, its performance is still reliable and can meet the production needs of enterprises.

2) Stable performance

Although it is an old equipment, it has undergone strict testing and debugging before being put into use. The performance of each component is optimized and adjusted to ensure the stable operation of the production line. In the production process, it can stably output high-quality seven-layer corrugated cardboard, which provides a reliable guarantee for the product packaging of enterprises.

3) High production efficiency

The old 7-layer cardboard production line is usually equipped with an advanced automatic control system, which can realize the automatic operation of the production line. From the delivery of base paper, the production of corrugated cardboard, drying, cutting to stacking, the whole process can be automatically completed, greatly improving the production efficiency. At the same time, the various parts of the production line cooperate with each other, and can quickly adjust the production parameters to meet the production needs of different specifications of products.

4) Energy saving and environmental protection

In today's society, energy conservation and environmental protection have become an important direction of enterprise development. The old 7-layer cardboard production line has fully considered the requirements of energy conservation and environmental protection in the design and manufacturing process. For example, dryers use efficient heating methods to heat up quickly, shorten drying times, and reduce energy consumption. At the same time, the coordination between the various parts of the production line is also more reasonable, reducing the waste of energy.

5) Strong customization

According to the different needs of enterprises, the old 7-layer cardboard production line can be customized. For example, the parameters and configurations of the various components of the production line can be adjusted according to the production scale and product specifications of the enterprise. At the same time, it can also increase some special functional modules according to the special requirements of enterprises, such as automatic feeding system, automatic detection system.

4. Application field

The seven-layer corrugated board produced by the old seven-layer board production line has the characteristics of high strength, good stability, excellent moisture resistance, etc., and is widely used in various heavy duty packaging fields. For example, the packaging of household appliances, furniture, machinery, electronic products and other industries requires the use of seven layers of corrugated cardboard. In addition, seven-layer corrugated cardboard can also be used to make display shelves, pallets and other products to meet the needs of different industries.
