A paper company corrugated board production line transformation plan

First, the implementation of the transformation

The disassembly and assembly of the production line is carried out by a professional transformation company, and the specific project transformation of the production line is carried out by a professional product production company.

Second, the purpose of the transformation

Mining production line potential

Increase average speed

Improve production line efficiency and reduce production costs

Adapt to future market needs

Third, the transformation plan

Cadre transformation

Under the premise that the speed of the production line is constant, the efficiency of the cadre equipment affects the efficiency of the entire production line. According to the equipment configuration of the Pearl River Delta and the Yangtze River Delta, the use of two vertical slitting machines and one stacking machine is the future production line configuration trend. Of course, the slitting machine adopts the bhs or Magui and other single-speed cutting machines with an international speed of less than 1 second.

It is recommended that the production line cadre equipment be equipped with one rotary cutting machine, two longitudinal cutting machines, one horizontal cutting machine and one hanging basket stacking machine.

Automated transformation

Frequency conversion is adopted throughout the line. Including the existing single-sided machine, double-sided machine, and suction motor drive motor into frequency conversion motor, using inverter control. This renovation can recover the investment within 5-6 months. The investment in this transformation is not big. It can be implemented by a local automation company or by a professional automation company in the industry.

Adopt production line measurement and control management system. The information is attached.

The erp tube system is used. Various professional companies have made a lot of publicity, and their functions are not described here.

Steam system transformation

Production line hydrophobic system transformation

The existing steam traps are rarely designed according to the actual situation of the production line. The steam flow of the production line is not calculated, so that the steam trap does not play its due role. The water in the gas equipment is not removed or exhausted in time, causing the surface temperature of the equipment to always go up or cool down during work, thus affecting the speed of the production line. The trap has no detection device and it is not easy to troubleshoot. It is recommended to use a new energy-saving steam trap with a detection device with a leakage rate of less than 5 , and a national standard of 3%. This transformation can save 3-5% of coal. It also provides a guarantee for steam condensate recovery.

Production line condensate recovery

Every 7 degrees of water entering the boiler can save 1% of coal. The condensed water on the production line is closedly recovered, and the comprehensive energy saving is over 26%. Today, the price of energy such as coal is soaring, its practical significance is even greater.

The above transformations must be carried out at the same time to achieve the desired results. The recommended recycling system is described in separate sources.

Paper feeder

The carton industry has entered the era of small profits, and the proportion of raw paper materials in carton costs is the largest, so the savings in raw paper and carton manufacturing companies are closely related. It is increasingly accepted by carton manufacturers as a paper machine that can obviously bring about the effect of saving the original paper on the tile line.

At present, the average speed of domestically produced tile lines is 60-120 m/min, but the speed of paper pick-up machines sold in the market generally reaches 150-250 m/min, and the price is expensive. It is obviously not economical to install such a paper machine on the middle and low-end tile lines. The recommended automatic paper machine information is attached.

Glue system transformation

A small cycle of glue is recommended.

The domestic enterprises that make automatic glue machines have Chengdu innovation, Chengdu Ao Ruida, Guangdong Xiaohua Electromechanical, Taiwan Yuhua, etc., which can be purchased when the time is ripe. For information, please inform in advance.

Whole plant logistics system transformation

The logistics system is of great significance for improving the efficiency of the workshop. Qingdao is represented by Mingwei, Minghui and other enterprises, and has become the production base of the logistics system of corrugated board industry.

Other technical transformation

Pressure-sensitive touch bar / spring type pressure bar

Evenly paste, reduce the amount of paste, save 5-10% of paste content

Prevent the collapse or flattening of the tip, keep the corrugated shape, and ensure the thickness and strength of the board.

Freely pass various papers without adjusting the height

Hot plate

Keep the corrugated molding to maximize the strength of the cardboard

Increase thermal efficiency by 60%, increase initial adhesion of paperboard bonding, and increase vehicle speed by more than 30%

Use plc computer control system to control the lifting cylinder, adjust the heat exchange through the lifting and lowering of the number of platen sections, ensure the flatness of the cardboard, reduce the obvious surface of the cardboard and the defective products caused by the wear and tear of the baking sheet.

Improve employee operability

The domestic transformation enterprises include Xiaohua Electromechanical, Hangzhou Dahua and other companies.

Other maintenance modifications

It is recommended to find professional manufacturers such as Haili and Dasong for corrugated rolls and rubber rollers that need to be repaired.
