Abstract
The utility model discloses a dandy roll for a cylinder machine. The dandy roll comprises annular spokes at two ends of the dandy roll, a plurality of axially-arranged inner ring-shaped racks and outer ring-shaped racks, wherein all outer ring-shaped racks are connected by a plurality of axial bars; the two annular spokes are connected with adjacent outer ring-shaped racks by a plurality of axial bars; the outer ring-shaped racks are connected with the adjacent inner ring-shaped frames by a plurality of spacing bars. The dandy roll is characterized in that the two adjacent outer ring-shaped racks are connected by a plurality of cross spiral inclined ribs; stainless steel surface wires are sequentially wound outside all bars and spiral inclined ribs along the axial direction. The dandy roll disclosed by the utility model has the advantages of light weight and excellent rigidity; the quality of paper making is improved.
Description
Technical field
The utility model relates to a kind of dandyprat for cylinder mould machine.
Background technology
Paper-making industry be one with national economy and the closely bound up industry of Social Culture industry, one of national economy ten large mainstay industries in developed country, and at present China's paper industry is being faced with culture, information, industry develop rapidly and the consumption structure great demand bringing of upgrading, industry development steps into the rapid growth phase, and paper industry has also become a popular industry of China's economic development.
Dandyprat is the critical component of paper machine, and is widely used at present fourdrinier machine.Existing dandyprat, no matter be chip dandyprat or spirally-wound type dandyprat, the shortcoming that ubiquity weight lays particular stress on, rigidity is poor, when work, amount of deflection changes greatly, affects papermaking quality.
Utility model content
The purpose of this utility model is for prior art above shortcomings, and a kind of cylinder mould machine dandyprat is provided, and it has advantages of lightweight, good rigidity, has improved papermaking quality.
For achieving the above object, cylinder mould machine dandyprat of the present utility model, comprise the ring type spoke at two ends, the interior cast frame of several axially-aligned and outer cast frame, all outer cast framves are all connected by axial several rods, two ring type spokes and adjacent outer cast frame are also connected by axial several rods, outer cast frame and adjacent interior cast frame are connected by several spacing bars, it is characterized in that two adjacent outer cast framves are connected by the spirality diagonal bar bar welding of several intersections, be arranged with successively vertically surface stainless steel silk outward at all rods and spirality diagonal bar bar.
The utility model is because two adjacent outer cast framves are connected by the spirality diagonal bar bar welding of several intersections, improve rigidity, with vertically successively the surface stainless steel silk of winding replace original grid sheet, not only weight is lighter, and the uniformity of rigidity and the uniformity of drainage are better, when work amount of deflection change little, improved papermaking quality;
As further improvement of the utility model, the Inner edge of all interior cast framves is connected by several axial strengthening rib strip welding; Further improve rigidity;
In sum, the utlity model has advantage lightweight, good rigidity, improved papermaking quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the partial enlarged drawing at C place in Fig. 1.
Fig. 4 is the partial enlarged drawing at D place in Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 to 4, this cylinder mould machine dandyprat, comprise the ring type spoke 1 at two ends, the interior cast frame 2 of several axially-aligned and outer cast frame 3, interior cast frame 2 is stainless steel concentric setting with outer cast frame 3, all outer cast framves 3 are all connected by axial several rods 4, two ring type spokes 1 are also connected by axial several rods 4 with adjacent outer cast frame 3, outer cast frame 3 is connected by several spacing bar 5 welding with adjacent interior cast frame 2, two adjacent outer cast framves 3 are connected by spirality diagonal bar bar 6 welding of several intersections, the Inner edge of all interior cast framves 2 is connected by several axial strengthening rib strip 8 welding, outside all rods 4 and spirality diagonal bar bar 6, be arranged with successively vertically surface stainless steel silk 7.
The utility model is because two adjacent outer cast framves 3 are connected by spirality diagonal bar bar 6 welding of several intersections, the Inner edge of all interior cast framves 2 is connected by several axial strengthening rib strip 8 welding, improve rigidity, with vertically successively the surface stainless steel silk 7 of winding replace original grid sheet, not only weight is lighter, and the uniformity of rigidity and the uniformity of drainage are better, when work amount of deflection change little, improved papermaking quality.
