1. Product introduction
Our new 5-layer paperboard line is an efficient production facility that integrates advanced technology. It is mainly used for the production of high quality 5-layer paperboard, which has a wide range of applications in the packaging industry. The production line from raw material input to finished cardboard output, the entire process design is scientific and reasonable, with a high degree of automation and precise control characteristics, to ensure stable and high-quality production.
2. Production process and principle
Feeding system
The line is equipped with a precise feeding device that can handle many different types of base paper simultaneously. The base paper is transported to the next stage of production at a steady speed and tension through an automated conveying system. This link also plays an important role in the quality detection and pretreatment of the base paper, which can find the defects of the base paper in time and make corresponding adjustments to ensure the smooth progress of subsequent production.
Gluing system
Using advanced gluing technology, the glue can be evenly and accurately coated on the base paper. Our gluing system can precisely control the amount of glue and the coating position according to different board requirements. This not only ensures the bond strength of the cardboard, but also avoids the waste of glue and reduces the production cost. During the coating process, the viscosity and temperature of the glue are strictly monitored and regulated to ensure the best coating results.
Composite and forming
The coated base paper is precisely superimposed on top of each other in the composite area, and the layers of base paper are firmly bonded together through the synergistic effect of pressure and temperature. In this process, the pressure control system and temperature control system of the production line cooperate with each other to ensure the flatness and structural stability of the five layers of cardboard. The formed cardboard has good physical properties, such as strength and stiffness.
Drying system
Drying is the key link to ensure the quality of cardboard. Our drying systems are designed to be energy efficient and quickly remove moisture from the cardboard through hot air circulation and precise temperature control, so that the cardboard reaches the right moisture content. In the drying process, the matching of the running speed and drying temperature of the cardboard has been carefully adjusted to avoid the quality problems such as deformation and cracking caused by too fast or too slow drying of the cardboard.
Cutting and stacking
The continuous paperboard produced is cut according to the preset size requirements, and the cutting precision is high, which can meet the diversified needs of different customers for the size of the paperboard. The cut cardboard is neatly stacked to facilitate subsequent packaging and transportation. In the stacking process, there is a special counting and sorting device to ensure that the number of each pile of cardboard is accurate and orderly.
3. Product performance characteristics
High quality output
Thanks to the precise control in all aspects of the production line, the produced 5 layers of cardboard are of high quality. The interlayer bond of cardboard is tight, the strength is high, and it can withstand greater pressure and impact force. Both in terms of flatness and dimensional stability are excellent, providing high-quality basic materials for subsequent printing, slotting, die-cutting and other processing processes.
High production efficiency
The highly automated design enables continuous and stable operation of the production line, reducing downtime caused by manual intervention. The fast feeding, gluing, compounding, drying and cutting stacking process greatly improves the production efficiency. Compared with traditional paperboard production equipment, our new production line has a significant increase in output per unit time and can meet the needs of large-scale production.
Flexibility and adaptability
According to the requirements of different customers can produce a variety of specifications and types of 5-layer cardboard. Whether it is different base paper material, board thickness or size requirements, the production line can be achieved by simple parameter adjustment. This flexibility allows the production line to adapt to the changing needs of the packaging market, providing customers with customized solutions.
Energy saving and environmental protection
Energy saving and environmental protection factors are fully considered in the design process. The drying system uses efficient heat recovery technology to reduce energy waste. The motor and control system of the entire production line are energy-saving design, which reduces operating costs and meets environmental requirements.
4. FAQ
Q: What about the degumming phenomenon between the produced cardboard layers?
A: First check the gluing system to see whether the glue is evenly coated and whether the amount of glue meets the requirements. It may be that the rubber roller is worn or blocked, resulting in uneven coating, and the rubber roller needs to be cleaned or replaced in time. At the same time, it is also necessary to check the surface condition of the base paper, if the surface of the base paper has impurities such as oil or dust, it will also affect the bonding effect, and it is necessary to clean the base paper. In addition, whether the compound pressure and temperature are appropriate also needs to be checked, if the pressure is insufficient or the temperature is too low, it may also lead to degumming problems.
Q: What is the cause of bending deformation of cardboard?
Answer: The bending deformation of the cardboard may be caused by uneven drying. Check whether the hot air circulation of the drying system is normal and whether the temperature sensor is accurate. If the hot air distribution is not uniform, it will lead to different parts of the cardboard drying speed is inconsistent, resulting in bending deformation. In addition, the uneven moisture content of the base paper or the inconsistent tension of the various layers of the base paper during the composite process may also lead to this problem, and it is necessary to check and adjust the tension control system in the pretreatment of the base paper and the production process.
Q: The production line is often shut down, affecting the production efficiency, how to solve?
A: There can be a variety of reasons for downtime. First check whether the feeding system has paper jam or base paper supply is not timely to ensure smooth feeding. Secondly, check whether the sensors in each link work normally, and the fault of the sensors may lead to the automatic shutdown of the production line. Also check whether there is a fault in the electrical control system, such as poor line contact and other problems. Checking and fixing these possible causes can effectively reduce downtime and improve productivity.
Q: How to further improve the production speed of the production line?
A: When considering increasing the production speed, it is necessary to comprehensively evaluate the matching of various links. First of all, ensure that the quality of the base paper can meet the requirements of high-speed production, if the strength of the base paper is not enough, there may be problems such as fracture during high-speed operation. Then check the equipment parameters of gluing, compounding, drying and other links, and adjust the parameters appropriately under the premise of ensuring quality, such as increasing the gluing speed, increasing the composite pressure, optimizing the drying temperature curve, etc., but these adjustments need to be carefully carried out, and verify the effect through trial production to avoid quality problems caused by too fast speed.
