From the quality of corrugated cardboard can be seen the production strength of an enterprise. Corrugated cardboard production line as the first production process of corrugated boxes, the cost and quality of products play a key effect, but also all production processes in the largest variables, the most difficult to control the link, only systematically solve the good, machine, material, method, the five elements of the ring, in order to reduce the occurrence of corrugated cardboard production line waste, make high-quality products.
People are the most crucial element, but also the most unstable element. Two aspects are emphasized here: the team spirit and personal operating skills of the corrugated board production line operators. Corrugated cardboard production line is a collection of steam, electricity, hydraulic, gas, machinery in one of the production line, involving single-sided machine, conveying over the bridge, glue compound, drying, pressing and crosscut and other key processes, any link cooperation is not in place, will affect the work of the entire production line. This requires corrugated board production line operators must have a fierce team understanding and the spirit of mutual cooperation.
At present, most of the enterprise’s corrugated cardboard production line operation and technical personnel are gradually groped and grown up in the production of the enterprise, and work with production experience, lack of professional operation skills training and learning, the driving ability of the equipment is not skilled enough, and lack of prediction and prevention of potential hidden problems. Therefore, enterprises should first pay attention to the skills training of corrugated cardboard production line personnel and the basic knowledge training of corrugated boxes, and pay attention to the cultivation of talents, establish a corporate culture with its own characteristics, and attract a high standard of corrugated cardboard production line technical personnel. So that the enterprise has a strong cohesion, employees have a high sense of identity.
The stable operation of the equipment is the foundation of the quality assurance of corrugated cardboard. In this regard, enterprises should carry out operations from the following perspectives:
1. Maintenance and protection of equipment is the primary task
A lot of waste occurs in the abnormal stop time of the corrugated cardboard production line, which constitutes a decline in production efficiency and an increase in production costs, and the maintenance and protection of equipment is the most useful way to reduce the shutdown rate.
2. Daily maintenance
Whether the equipment can work normally depends to a large extent on whether the daily maintenance operations can keep up, the general equipment maintenance principle is: smooth and abundant, clean and complete, careful and meticulous.
Corrugated board production line has hundreds of smooth parts, according to the use of different smoothing agents, can be divided into oil smooth parts and grease smooth parts, different smooth parts should be strictly used the corresponding smoothing agent, and to keep smooth parts get full smooth. If the corrugation roller, pressure roller temperature is high, it is necessary to strictly use high temperature smooth grease.
The cleaning operation of the equipment also plays an important role in the maintenance process, which is closely related to the smooth condition of the equipment, and the first thing should be no dust and no debris, to prevent the influence of dust and debris to accelerate the wear and even damage of the parts.
3. Repair operations
The equipment part should draw up specific repair plans and implement them according to the problems presented in the process of equipment operation to ensure the stable operation of the equipment.
4. Management of equipment wearing parts
Real-time monitoring is very necessary for the management of equipment wearing parts. Enterprises should set up equipment wearing parts using tracking accounts, real-time monitoring, analysis, find out the reasons for wearing parts faster, formulate countermeasures, can be prepared in advance, to prevent the damage of wearing parts caused by no plan shutdown.
Under normal circumstances, the management of wearing parts should take the following two approaches: one is to change the raw materials and production process of the wearing parts themselves, in order to reach the purpose of extending the service life; The second is to use it in a reasonable application environment to reduce unnecessary damage caused by human and environmental factors.
5. Pay attention to the renovation of key parts of equipment
In recent years, the technical innovation of the corrugated cardboard production line has emerged in an endless stream, and the new technical highlights have led enterprises to embark on the renewal and transformation of key components of the corrugated cardboard production line equipment.
6. Production management system
The use of corrugated board production line production management system to control the production cost, can more accurately calculate the production efficiency of corrugated board production line, complete the entire production line speed synchronization. Generally, the waste rate of corrugated cardboard can be reduced to more than 5%, and the amount of starch is also significantly reduced.
① Active paper feeder
Choose an active paper splicer for paper splicing to prevent unnecessary waste during paper splicing, reduce the shutdown of the corrugated board production line and the occurrence of quality problems, and ensure a stable and high production speed and high cardboard quality of the entire production line.
② Tungsten carbide corrugated roller
The corrugated roller, as the heart of the single-sided machine, plays a decisive effect on the quality of the corrugated board and has a direct impact on the economic efficiency and production of cattle. Tungsten carbide corrugated roller is a special process that uses thermal spraying technology to melt and spray tungsten carbide alloy powder to the corrugated roller tooth surface to form tungsten carbide coating, which is 3-6 times longer than the general corrugated roller life. In the whole working life of the roller, its corrugated height is almost unchanged, ensuring the stable quality of the corrugated board, reducing the amount of corrugated core paper and glue paste by 2% to 8%, and reducing the occurrence of waste products.
③ Paste machine contact rod
Paste machine contact bar is made of a lot of wear-resistant curved plate and spring connection, the spring elasticity always makes the curved plate evenly fit on the paste roller, even if the paste roller is worn and depressed, the spring plate will also be depressed, always let the corrugated core paper evenly fit on the paste roller. In addition, the spring with balanced elasticity will actively adjust the concave and convex according to the thickness of the base paper and the change of the corrugated shape, so that the corrugated height of the corrugated core paper when entering the pasting machine and the corrugated height of the pasting machine after the pasting machine are ensured to remain unchanged, which can control the amount of glue and greatly improve the quality of the cardboard.
④ Hot plate part contact plate
The hot plate contact plate is used to replace the traditional gravity roller contact heat transfer method. It is made of specially made wear-resistant material sheet board, each sheet board is equipped with a elastic balanced spring, so that each sheet board can fully touch the hot plate, increase the heating area of the cardboard, improve the heat transfer efficiency, and then improve the speed, ensure the missing corrugated shape, enhance the strength of the corrugated board and increase the thickness of the corrugated board, the cardboard does not deglue, does not bubble, excellent fit, Reduced scrap rate.
⑤ Active paste system
Paste making process is the most volatile process in the whole production process and has the most critical effect on the quality of paperboard. The traditional paste formula is single, and the filling is easy to be inaccurate due to human factors, which makes the adhesive quality unstable. The active paste making system is a typical synthesis integrating technology, machinery and active control. It can process the formula function, historical data, real-time data, dynamic monitoring function and man-machine dialogue in the paste making system. The paste making quality is stable and controlled, which can make the production line operation more stable, reduce human factors, and completely solve the quality problems such as cardboard foaming, transparent and soft. Reduce scrap rate.
