Tungsten carbide corrugated paper roll made of Meijia
Corrugated board production line
The complete corrugated board production line includes the following machines: rolling mill stand, preheater, splicer, single facer, viaduct, multi-purpose preheater and gluing machine, double bread dough machine, slitting machine, slitting and stacking Machine waiting.
The raw paper roll is fed into the roll stand. After being heated by the preheater and adjusting the moisture, the base paper will enter the single-sided corrugator, corrugate from this, and bond with another base paper to become a single-sided corrugated paper. Then it is conveyed through the roof bridge, reheated by the multi-layer preheater, glued by the gluing machine, and connected by the double bread machine cutting machine. Then, continuous corrugated cardboard comes out.
After cutting and scoring through the slitting machine, and cutting horizontally through the edge trimming machine, corrugated cardboards of different sizes are produced. Finally, these corrugated cardboards of different sizes will be stacked, calculated and sent out by the stacker.
Heating method: using steam heating.
Advantange corrugated roll:
1. The coating is firmly combined with the substrate to ensure long-term use of the coating without falling off;
2. The hardness of the coating is high, the wear resistance is doubled, and the life is linearly extended;
3. The coating thickness is uniform and controllable, which can ensure the accuracy of the corrugated wheel;
4. The surface roughness before coating can reach ra0.3-0.5um. After grinding with a special diamond grinding wheel cutter, the surface roughness reaches and is higher than that of the electroplated hard chrome roller.
5. With UV-type corrugated design, it can effectively improve the hardness of the cardboard and reduce the amount of paste and the waste of core paper;
6. When the corrugated type is used, there will be abrasion in theory, and the paper output rate will remain unchanged for a long time;
7. Since the corrugating roller used this machine, the thickness of the cardboard produced remains unchanged, the printing is always smooth, and the quality of the cardboard and cartons is stably controlled;
8. Using special methods to remove the coating, the wheel blank can be reused;
9. The extension of the service life reduces the frequency of replacement, and also saves labor and material costs;
