The production of an enterprise can be seen from the quality of corrugated cardboard. As the production process of corrugated boxes, the corrugated board production line plays a key role in the cost and quality of the product. It is also a link in all production processes that is variable and difficult to control. Only a systematic solution of people, machines, materials, methods, and environmental Only five factors can reduce the production of waste products on the corrugated board production line and produce high-quality products.

People are the key factor and also the unstable factor. Two aspects are mainly emphasized here: the team spirit and personal operating skills of the corrugated board production line operators.

The corrugated cardboard production line is a production line integrating steam, electricity, hydraulic pressure, gas and machinery. It involves multiple key processes such as single-sided machines, conveying bridges, gluing and compounding, drying, crimping, and vertical and horizontal cutting. Inadequate coordination will affect the operation of the entire production line, which requires the corrugated cardboard production line operators to have a strong sense of teamwork and mutual cooperation.

At present, most of the company’s corrugated board production line operation technicians have grown up slowly in the production of the company. They work with production experience, lack of training and learning of operating skills, and are not skilled enough in equipment control and lack of correctness. Prediction and prevention of potential problems. Therefore, companies should first focus on the skills training of corrugated cardboard production line personnel and the training of corrugated cardboard box-related basic knowledge. They should not hesitate to invite people to come or send out to learn, and they should focus on the cultivation of talents, establish a corporate culture with their own characteristics, and attract The high-level technical talents of the corrugated cardboard production line make the company have strong cohesion and employees have a high sense of identity.

The stable operation of equipment is the foundation of corrugated cardboard. In this regard, companies should proceed from the following perspectives:

1. The maintenance and maintenance of equipment is the primary task

The abnormal shutdown of the corrugated board production line will produce a lot of waste, resulting in a reduction in production efficiency and an increase in production costs. Equipment maintenance and maintenance are the methods to reduce the downtime rate.

2. Daily maintenance

Whether the equipment can operate normally depends largely on whether the daily maintenance work can keep up. The general equipment maintenance principle is: adequate lubrication, complete cleanliness, and carefulness.

corrugated board production line has hundreds of lubrication parts, which can be divided into oil lubrication parts and grease lubrication parts according to the different lubricants used. Different lubrication parts should be strictly used with corresponding lubricants and the lubrication parts should be fully lubricated. If the temperature of corrugating roller and pressure roller is high, high temperature grease must be used strictly.

The cleaning of equipment also plays an important role in the maintenance process. It is closely related to the lubrication status of the equipment. It should be dust-free and free of debris to avoid accelerating component wear and even damage due to the influence of dust and debris.

3. Maintenance work

The equipment department shall formulate and implement a detailed maintenance plan based on the problems that occur during the use of the equipment, and the equipment will operate stably.

4. Management of vulnerable parts of equipment

It is very important for the management of equipment wearing parts and real-time monitoring. Enterprises should establish a tracking account for the use of vulnerable parts of equipment, conduct real-time monitoring and analysis, find out the reasons for faster wear of vulnerable parts, formulate countermeasures, and be able to prevent unplanned downtime due to damage to vulnerable parts.

Under normal circumstances, the following two measures should be taken for the management of wearing parts: one is to change the material and manufacturing process of the wearing parts to achieve the purpose of prolonging the service life; the other is to use in a reasonable environment to reduce man-made , No damage caused by environmental factors. 5. Pay attention to the new transformation of key parts of equipment

In recent years, technological innovations in the corrugated board production line have emerged one after another. With new technological highlights, enterprises have embarked on the new transformation of key components of the corrugated board production line.

6. Production management system

Use the corrugated board production line production management system to control the production cost, can more accurately count the production efficiency of the corrugated board production line, and realize the speed synchronization of the entire production line. Generally, the waste rate of corrugated board can be reduced by more than 5%, and the amount of starch is also significantly reduced.

①Automatic paper splicing machine

The automatic paper splicing machine is used for splicing paper to avoid unnecessary waste during splicing, reduce the downtime of the corrugated cardboard production line and the occurrence of quality problems, stable high production speed and high cardboard quality of the entire production line.

②Tungsten carbide corrugated roller

As the heart of the single-sided machine, the corrugated roller plays a decisive role in the quality of corrugated board, and it also has a direct impact on the economic efficiency of cattle production. Tungsten carbide corrugated roller is a process that uses thermal spraying technology to melt and spray tungsten carbide alloy powder onto the tooth surface of the corrugated roller to form a tungsten carbide coating, which is 3 to 6 times longer than normal corrugated rollers. Throughout the life of the roller, its flute height is almost unchanged, the quality of corrugated board is stable, the consumption of corrugated core paper and glue is reduced by 2% to 8%, and the generation of waste products is reduced.

③ Pasting machine touch stick

The pasting machine contact pressure bar is made of many wear-resistant arc-shaped plates connected with springs. The elastic force of the spring always makes the arc-shaped plates fit evenly on the gluing roller, even if the gluing roller is worn out, the spring plate is With the depression, the corrugated core paper is always evenly attached to the glue roller. In addition, the spring with balanced elasticity will automatically adjust the height 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 is unchanged, and the glue is controlled. The quantity and the quality of cardboard are greatly.

④The hot plate part touch plate

The hot plate contact pressure plate is used to replace the traditional gravity roller contact pressure heat transfer method. It is made of special wear-resistant material sheets and plates. Each plate is equipped with a spring with balanced elasticity, so that each plate can touch the hot plate, which increases the heating area of ​​the cardboard and improves Heat transfer efficiency, which can increase the speed, improve the corrugated shape, enhance the strength of the corrugated cardboard and increase the thickness of the corrugated cardboard. The cardboard does not degummed, does not foam, and has good bonding, which reduces the waste rate.

⑤Automatic paste making system

Paste making process is a key process that has large fluctuations in the entire production process and has an impact on the quality of paperboard. The traditional paste-making formula is single, which is likely to cause inaccurate feeding due to human factors, which makes the quality of the adhesive unstable. The automatic paste making system is a typical complex integrating process, machinery and automatic control. It can process the recipe function, historical data, real-time data, dynamic monitoring function, man-machine dialogue, etc. in the paste making system, and the quality of paste making Stable control can make the operation of the production line more stable, reduce human factors, solve the quality problems of cardboard blistering, permeation, and softness, and reduce the waste rate.
