We are impregnation line manufacturer located in Nantong, focus on supply one step/two step impregnation line width 4ft-8ft. 

Melamine paper impregnation line

It is used for impregnating and drying surface paper, furniture décor paper, HPL surface etc.For our high end impregnation line, let me explain for you in a brief:

Unit 1, rotary shaft less ram radial un-winder with positive tension control, with auto slicer jointing; also, there is two roller of paper can be different pattern. The PLC can counter expected quantity of paper (order or production qty), stop one roller and automatically shift to another pattern roller.

 

Unit 2, High accuracy doctor roller in impregnation unit; gap between two doctors can be adjusted by synchronized electric-screw, step adjustment is 1/76mm, glue pickup accuracy is per micro-gsm;

In impregnation unit, there is also other features device adopted:

2.1 Electrical hoisting banner roller, can be upper and down leveling to matching the surrounding temperature to match glue permeability a2.nd operating speed, it acts as to give an extra impregnation distance in the sky;
2.2 Bath liquid level is auto filling, there is a close feedback in circulation of glue barrel and impregnation glue bath;

2.3 Company logo printer can be adopted to realize anti-forgery. 
 

Unit 3, Pneumatic vertical auto-door in drying chamber, easier for cleaning and maintenance; inner hot air distributing equally onto paper upper and down, not waving, and non-touching onto air-blow in a floating way;

3.1 In some case, if thermal oil boiler fuel is cost sensitive, we can adopt waste-gas -heating recycle system;

3.2 Update feature: we can also adopt separate CNG burner, hot air exchanging and storage on top of ovens, thus a general thermal boiler can be cancelled;

3.3 Option feature, chamber inner humidity inspection, help to act non-worker operating;Unit 4, Update mesh roller glue coating to be squeezing glue apply in 2nd coating unit; glue can be also upper MF, and down side paper UF coating.

4.1 Here, we also adopt web-aligner; to keep paper working in one line;

Unit 5, Update cooling chamber from air cooling to be cooling with humidity remover, enhance the cooling effective;

Unit 6, Web-aligner and tension control before paper tractor

Unit 7, Tension control before cutter

Unit 8, Rotary cutter, high accuracy with tolerance less than 1mm

8.1 Upper touching tension control roller, avoiding paper slide before cutting

8.2 In some case, synchronized paper process, an extra online Paper Mark inspection, the paper cutting length can be exactly in Paper Cross-mark;

Unit 9, Self-hoisting paper stacking unit;

9.1 Accessory paper packing device, easier for paper package in a certain piece and labeling when wrapping and packing.

The whole line control can be Mitsubishi, Siemens or Schneider, SEW motor with Taiwan original decelerator.
