The utility model can better overcome the defects of rough screen surface, poor integral structure and easy corrosion, etc. in existing round screen sheets. The utility model has the advantages of high uniformity on the screen surface, good dewatering effect, corrosion resistance, low cost, convenient maintenance, etc.
Description
The utility model relates to a kind of papermaking equipment, particularly relates to the plastic sheet type cylinder that a kind of paper machine is used, and is the improvement to existing paper machine cylinder.
Cylinder is the indispensable device of dewatering of pulp moulding in machine hand's preface, when copying paper, at first paper making raw material to be pulverized pulping, add water and deliver in the net groove, by the startup of paper machine, the drive cylinder rotates, paper pulp is suspended on the wire side that is covered with on the cylinder thereupon, by wet end dehydration be located at the roll extrusion of the rubber-surfaced roll of wet end, the moisture content drop is gone out, paper pulp is sent to drying cylinder and becomes paper, and this technical process requires tighter to the uniformity of wire side.At present, the paper machine cylinder that generally use in the paper mill is the Wound-rotor type iron structure cylinder of always using till today decades, promptly uses copper rod as support on wire side, carves indenture by the interval on the copper rod, red copper wire twines at each indenture place spiral, forms whole cylinder face.The weak point of this structure is that the copper cash degree of tightness is inconsistent, causes wire side uneven, and overall structure is poor, off-line and damage easily, and complex process, and corrosion-resistant degree is low, the cost height.
The purpose of this utility model provides a kind of wire side good evenness, the precision height, and dehydrating effect is good, and is corrosion-resistant, and cost is low, and technology is simple, plastic sheet type paper machine cylinder easy to maintenance.
The technical solution of the utility model is: by net axle 1, be installed in left outer spokes 8 on the net axle 1, right outer spokes 16 and a plurality of in spoke 6 and be installed in the spacer sleeve 2 between each spoke on the net axle 1 and the cylinder sheet 12 that is installed on the spoke outer surface constitutes, it is characterized in that cylinder sheet 12 is by the injection molded net sheet that is made of several support links 17 of erectting the radially thin slice 18 arranged and several axially-aligned of plastics one.
Advantage of the present utility model is: because the cylinder sheet changes Wound-rotor type copper and iron structure in the past, adopt the radially thin slice of setting arrangement and the support links of axially-aligned to be connected structure into the net, make that whole wire side is smooth, precision is high, dehydrating effect is good, and the paper moulding is equal; And the cylinder sheet has changed the mode that old-fashioned cylinder monolithic is installed, the structure that the bearing pin that employing element mesh sheet is mutual and the inserting mode of shrinkage pool link into an integrated entity, make technology simple, overall structure is good, the radially bearing capacity of wire side is apparently higher than existing cylinder, and mounting process is simple, is provided with seam simultaneously on the circumferential inner wall of spoke and cylinder sheet junction, can play better radial support effect.Of the present utility model being also advantageous in that: overcome original old-fashioned cylinder sheet and adopted the drawback that the copper-steel material material is perishable, cost is high, except that net axle and standard component, all the other all adopt plastics to make, reduce production costs 50%, and it is repeatedly reusable, easy to maintenance, corrosion-resistant degree height, technology is simple.
