The new 3-layer paperboard production line is a professional equipment integrating advanced technology and efficient production, designed to meet the needs of paper packaging products manufacturers such as cartons and cartons for high-quality 3-layer paperboards.
1. Overview of the production line
The new 3-layer paperboard production line is a professional equipment integrating advanced technology and efficient production, designed to meet the needs of paper packaging products manufacturers such as cartons and cartons for high-quality 3-layer paperboards. The production line from the base paper input to the final cardboard molding, after careful design and optimization, with a high degree of automation, high production efficiency, cardboard quality stability and many other advantages.
2. Core components and functions
(1) Base paper holder
The base paper holder is the starting part of the production line, which can stably carry and transport the base paper. Made of high-strength steel, it has good structural stability and can adapt to different width and weight of base paper rolls. At the same time, the base paper holder is equipped with an advanced braking device, which can accurately control the unwinding speed of the base paper, ensure that the tension of the paper is uniform during the entire production process, and avoid the folding or breaking of the paper due to tension problems.
(2) Preheater
The preheater plays a crucial role in the paperboard production process. By preheating the base paper, it adjusts the humidity and temperature of the paper to make it easier for subsequent processing. The preheater of the new 3-layer board production line uses an efficient heating method, which can heat the base paper to the right temperature in a short time, and the temperature control accuracy is high, which can be flexibly adjusted according to different paper types and production process requirements. This not only helps to improve the strength and stiffness of the cardboard, but also improves the flatness of the cardboard.
(3) Single-sided machine
Single-sided machine is the key equipment for forming single-sided corrugated cardboard. The single side machine of the production line adopts advanced corrugating roll technology. The material of corrugating roll is made of high quality alloy steel. After special heat treatment and surface treatment, it has high hardness, high wear resistance and good thermal conductivity. This allows the corrugated roller to maintain a stable corrugated shape under high-speed operation, and produces a corrugated height and uniform shape. At the same time, the single-sided machine is equipped with an automatic gluing system, and the amount of glue can be precisely controlled to ensure that the glue is evenly coated on the corrugated peak, so that the adhesion of the cardboard is firm, and the overall quality of the cardboard is improved.
(4) Transport over the bridge
The conveying bridge connects the single-sided machine and the double-sided machine, which is responsible for the smooth transportation of single-sided corrugated cardboard to the next process. Conveying over the bridge adopts a unique suspension design, which can effectively reduce the friction and vibration of the cardboard in the conveying process and avoid damage to the formed corrugated structure. In addition, the conveying bridge is also equipped with a tension control system to further ensure the tension stability of the cardboard during the conveying process.
(5) Double-sided machine
Double-sided machine is the core equipment that combines single-sided corrugated cardboard with another layer of paper into 3 layers of cardboard. The double-sided machine of the new production line adopts the method of hot plate heating and pressure roller pressure. The temperature distribution of the hot plate is uniform, and the pressure of the pressure roller can be accurately adjusted according to the thickness and material of the cardboard. This design can ensure the good adhesion between the face paper and the single-sided corrugated cardboard, so that the interlayer bonding force of the cardboard is strong, and it is not easy to stratification. At the same time, the double-sided machine also has an automatic correction function to ensure the accurate position of the cardboard in the composite process, improve production efficiency and cardboard quality.
(6) Crosscutting machine
The crosscutting machine is used to cut continuously produced cardboard to a set length. The cross-cutting machine adopts high-speed flying knife cutting technology, and the material and edge design of the flying knife are carefully optimized to achieve fast and accurate cutting at high speed. At the same time, the crosscutting machine is equipped with an advanced photoelectric tracking system, which can monitor the running speed and position of the cardboard in real time, and automatically adjust according to the set cutting length to ensure the accuracy of the cutting size, and the error can be controlled within a very small range.
(7) Stacker machine
Stacker is the last process of the production line, which neatly piles up the cut cardboard. The stacker of the new 3-layer paperboard production line adopts an intelligent control system, which can automatically adjust the stacker mode according to the size and weight of the paperboard to ensure the uniformity and stability of the stacker. The stacker also has a counting function, which can accurately count the number of cardboard produced and facilitate production management.
3. The advantages of production technology
(1) Automated production
The entire production line is highly automated, from base paper unwinding to cardboard stacking, all aspects are coordinated and monitored by advanced control systems. The operator only needs to set the production parameters in the central control room, and the production line can run automatically, which greatly reduces the workload and error rate of manual operation, and improves the stability of production efficiency and product quality.
(2) Quality control
The production line is equipped with high-precision detection and control equipment in each key link. For example, the amount of glue coating can be precisely controlled in the gluing link, the temperature, pressure and other parameters can be accurately controlled in the cardboard composite link, and the accuracy of the cutting size can be guaranteed in the cutting link. These quality control measures ensure that the produced 3-layer paperboard meets high quality requirements in terms of thickness, strength, flatness, etc.
(3) Flexibility and adaptability
The new 3-layer cardboard production line can adapt to A variety of different types and specifications of base paper, and can produce different types of corrugated (such as A corrugated, B corrugated, C corrugated, etc.), different thickness and different strength of 3-layer cardboard. At the same time, the production speed of the production line can be flexibly adjusted according to the needs of the order, which can meet the needs of large-scale production, but also adapt to the customized production requirements of small batches and multi-varieties.
4. Product quality and application areas
(1) Product quality characteristics
1. High strength: the interlayer combination of cardboard is firm, the corrugated structure is stable, can withstand greater pressure and impact force, and meet the protection requirements of packaged products during transportation and storage.
2. Good flatness: the surface of the cardboard is flat, without obvious wrinkles, bubbles and other defects, which is conducive to subsequent printing, grooving and other processing processes.
3. Stable dimensional accuracy: the size of the cardboard after cutting is accurate, and the deviation is small, which ensures the consistency of the specifications of the packaging products.
(2) Fields of application
1. Carton packaging: It is widely used in the outer packaging carton production of various commodities, such as electronic products, food, daily necessities and other industries. High quality 3-layer cardboard can provide reliable protection for goods, but also meet the requirements of the carton in terms of printing and aesthetics.
2. Carton packaging: For some carton products with relatively low packaging strength requirements, but high appearance and printing quality requirements, such as cosmetic boxes, gift boxes, etc., the cardboard produced by the production line can also meet its production needs.
