Summarize
 
Corrugated cardboard production line is the key to the corrugated carton production enterprise production equipment.Corrugated cardboard enterprise faces the increasing fierce market competition because of the corrugated cardboard users paying more attention on order specifications, small quantity and fast delivery,that's why we must improve the automation of corrugated board production line, the same as the level of corrugated board production line of production management including improve quality and efficiency, save energy and manpower, reduce supplies and  waste, the purpose of equipment is key to achieve this goal, including cadres corrugated cardboard enterprise dealing with the cadres of the old production line equipment to conduct a comprehensive upgrade, The new production line shall be equipped with automatic cadre equipment with production management system.
 
Operating Principle
 
Corrugated board production line is pressed corrugated roller base paper,glue,paper separating, cutting into different size,the last working procedure of assembly line by code output, etc. Such as single-sided corrugated paper production line is usually composed of web support, single face corrugated board forming machine, rotary paper cutting machine, using roll paper materials and potato or corn starch adhesive, continuous production and cut into the required specifications of the single face corrugated board.Cardboard don't have to dry.It can produce more than three layers of corrugated cardboard.

Structure & Features
 
It is a kind of bridge type conveyor transport the single corrugated paper to tension brake or adsorption brake by tracker and conveyor for next process.
Adopt suction tension device, high pressure centrifugal converter adsorb the papers by vacuum, electric rectification, assured the paper flat.
Electric elements controlled the two sets operation board, it can be adjusted above and below the bridge separately.
The tracker use the chain drive to pull the single corrugated paper to the bridge together with the single facer. The conveying speed is slow to that can form the wave overlap for production line.
