Cylinder is the main part in cylinder paper machine on which the paper width is formed.It is required to filter water evenly and not produce too much stirring in the trough when rotating.The cage should have sufficient stiffness and accurate geometry and should be installed horizontally.
The rotary shaft is fitted with a brass support bar device called spokes, with spokes spaced 100-150mm apart.The spokes support the central rim of the wheel, which is surrounded by grooves with horizontal bars of the same length as the net cage.
The horizontal strip is about 1cm in diameter and 4cm from the center, parallel to the central axis.The bar is made of steel or brass and the section may be round or rectangular.There are protruding wheel rings on the outermost wheel rings, which are used to seal the corresponding parts of the net groove, so as to isolate the inside and outside of the cylinder.In the horizontal bar according to the spiral milling out of serrated groove, with a continuous diameter of about 3mm of metal wire spiral wound in the cylinder, then form a cage cylinder frame.The gap between adjacent wires is about 1cm.
Finally, the copper wire is first covered with a thick brass or stainless steel inner mesh, and then covered with a thin surface mesh for paper making.In the wire and face wire are terminal net, is a special tool to tighten in the cylinder frame, with silver welding or welding butt up.The final assembly must concentric with the central shaft, and its stiffness should be sufficient to withstand the pressure of the volute roll without deformation.
The cylinder bearing device is outside the net groove.The two ends of the cylinder are connected with the side box of the net slot.Slurry after the Internet, through the copper mesh filter into the cylinder of white water, from both ends of the cylinder into the side box, and then out of the white water pump circulation.
Advantage of Cylinder Mould
1. High speed: dynamic balance detection, 800 meters;
2. The weight is reduced by 30% compared with ordinary culinder mould,reducing
energy consumption;
3. Each spoke is accurately measured to avoid the heaviness of the net cage, reduce the friction of the net cage on the blanket and net, and reduce production costs;
4. All spokes are U-shaped design to reduce the water resistance, and the surface is very smooth; the vehicle speed can be increased by 15-30 meters than the ordinary iron cage without water throwing phenomenon;
5. The strength is several times higher than that of ordinary net cages, and it is resistant to punching and reduces the maintenance rate of net cages;
6. High mesh surface flatness, increase filter area, increase output, and improve paper quality;
7. Acid and alkali resistant, standard 304 stainless steel material;
8. Very strong integrity and durable.
Winding / String Chip Type
Winding type
Slice being weled on every rod and solice in fall |
String Chip type
Rod goes through the solice |
| Winding type cylinder mould is widely being used as its high stability and long service life compared to string chip type. |
