Double layer /2 ply corrugated cardboard production line

　　Technical Parameter

　　Electrical Mill Roll Stand

　　Features

　　1. Electrical shaftless mill roll stand, which is used in corrugated cardboard production line, its function is supporting the paper mill roll.

　　2. Symmetrical structure can install two rolls of paper at the same time and continually change paper.

　　3. Paper roll clamp-loosen, life-lower, movement, contraposition, translation operated by electric driven.

　　4. Max. diameter: Φ1600mm

　　5. Range of width: 1200mm-1800mm

　　6. Pneumatic or manual control web tension

　　Single Facer corrugated rewinding machine

　　Features

　　1. Design Speed: 100m/min.

　　2. Effective width: 1200mm-2500mm

　　3. The diameter of corrugated roller: 280mm.

　　4. Type of corrugated roller A/B/C/D/E/F/G

　　5. Cardboard transmit adopts vacuum suction method, with wind control system. Keep flute profiles stable of the lower-roller in the condition of running up.

　　6. The upper-lower corrugated roller are made of high quality 48CrMo alloy steel and heat-treatment. The rigidity is HRC58-60 degree, the surface are grinded.

　　7. Upper and lower corrugated roller are unit assemblage, the whole corrugated rollers group can be move and quick replacement, to change flute type quickly.

　　8. Drive decelerate box adopts oil immersed type lubricating to reduce noise. Keep running stable.

　　9. Single face lift-lower of upper corrugated roller, pressure roller and gluer roller are controlled by pneumatic control.

　　10. Glue parts adopt auto supply glue circularly.

　　11. The glue part surface are treated by special mesh snicked and chrome plated.

　　12. Glue part can be running independently or non-independently while stopped. Adopt main motor frequency conversion control.

　　13. Bearing of corrugated rollers, and pressure roller adopt high-temperature lubricate grease to keep running smoothly and durably.

　　Paper cutter

　　Single cutter can do single corrugated cardboard vertically and horizontally cutting. It has change order fast and high cutting precision, working speed fast etc. make litter waste, when changing the order. It suits for the top grade color printing machine. This machine adopts PLC touch screen to design. Through it operator can know all the production status. Adopt variable frequency motor to adjust the speed. Servo control make the cutting length more exactly, making the cutting precision perfectly. (error ±1.5mm).

　　Lifetime is 6-8 million meters

　　1. Computer aided design is adopted to set the product parameters scientifically, which ensures every piece of our design is economical, reliable and of high quality

　　2. CNC planer type corrugating roll high-precision grinding machine group and additional high-precision grinding machine group are available, which all work for corrugating rolls

　　3. Computerized control to grind the concave rolls

　　4. Selected high quality 48CrMo and 50CrMo alloy steel forged pieces (coating)

　　5. Advanced technology for multilayer processing on high-precision machines

　　6. Advanced heat treatment process is used for quenching and tempering to obtain uniform mechanical properties

　　7. German advanced aquatensid SZ polymer quenching with intermediate frequency, the resultant hardened layer> 7 mm, hardness> HRC58 (HS73-80), uniform hardness with no soft zone

　　8. We use the most advanced high-efficiency atotechheef-25 micro cracks functional chromium plating technology and equipment, to get more rigid, smoother, more wear-resistant hard chrome coating

　　Lifetime is 25% longer than those resulted from ordinary electroplating

　　9. Refurbishment for old corrugating rolls is available

　　Check before installation

　　Pre-installation check items:

　　(1) Cleaning Check the corrugated surface (including surface plating quality).

　　(2) Cleaning Check the fastening parts (including internal and external threads).

　　(3) Check the corners of the corrugated roll and the high (the entire roll from both ends to the middle are divided into five or more measurement points. High detection points must be odd, the high data should be symmetrical on both sides). With the corresponding specifications of the diameter micrometer (OD micrometer general mechanical and electrical companies can buy).

　　(4) check the corrugated roll high. Measured with a needle depth gauge (needle depth dial indicator is not currently available for domestic purchase, or imported from an ordinary depth dial indicator).

　　(5) Cleaning Check the outer diameter and appearance of the shafts of the corrugated roller, and the outer diameter is measured with the corresponding outer diameter micrometer.
