Abstract
Disclosed is an arc roller belonging to paper-making machine components. The arc roller comprises arc shafts and rubber sleeves. Multi-cylinders are continuously sheathed on the arc shafts and fixed by roller bearings. Both ends of the arc shaft are provided with splicing sleeves. The splicing sleeves are provided with roller casings and connect with rubber sleeves. Block rings for hole, plugs and oil seal covers are arranged on the shaft sleeves. The arc roller adapts to both the broadloom paper machine with high speed and the old style and obsolete paper machine with low speed. The arc roller equally distributes the paper pulp on the net spreading part, felt, dry net and paper to keep the surface of the paper straight and smooth, so that the quality of the paper is obviously improved.
Description
The utility model is a kind of bowed roller, belongs to the parts of papermaking equipment.
At present, employed bowed roller in the papermaking equipment puts a gum cover by arc shaft (polished rod or screw rod are arranged) and is formed.Its shape has D shape roller, adjustable bow curved roll or olive roller etc.This roller is used to unfold the paper pulp on wet end, woollen blanket, dried net, the page etc., it is rotated by gum cover direct friction on arc shaft and finishes, the structure of this bowed roller, only be suitable for the low speed of a motor vehicle and use on the paper machine of face in a narrow margin, and the paper machine that is unsuitable for the high speed of a motor vehicle and wide format uses, because, fabric width is relevant with the length of bowed roller, fabric width then bowed roller is just long, therefore, just produces following problem: behind (1) bowed roller lengthening, increase by paper pulp amount on the bowed roller accordingly, be that weight increases, impel the bowed roller distortion, then bowed roller just can not keep the line style of original arc; (2) web part of paper machine, woollen blanket, dried net, page etc. are to drag the carrying row on bowed roller, and gum cover is by ballast such as paper pulp and the passive paper pulp of unfolding on wet end, woollen blanket, dried net, the page that rotates overcoming friction on the arc shaft; Because paper pulp weight increases, the coefficient of friction of gum cover and arc shaft increases, and then resistance increases, and is in fact must resistance bigger as improving the speed of a motor vehicle, forces bowed roller to add large deformation, and the line style of its former arc is out of shape also bigger; Consequently destroy the line style of the original arc of bowed roller, just can not reach the paper pulp effect of effectively unfolding uniformly on wet end, woollen blanket, dried net and the page; Because arc is that bowed roller reaches even distribution to unfolding paper pulp, guarantee that the paper of page is straight and upright, smooth, improve the basic assurance of the papery of page.In addition, because this bowed roller is that gum cover is nested with on arc shaft, both are non-sealing states; During work, pulp liquor can be penetrated on the arc shaft, it is got rusty and corrodes, so need often to change bowed roller, influence is produced, and cost improves.
In order to overcome the problem of above-mentioned existence, the purpose of this utility model is the structure of existing bowed roller is improved, and makes it keep good arc line style of bowed roller and gum cover and arc shaft to be in bowed roller among the sealing state when work.
The purpose of this utility model is achieved in that it is a kind of bowed roller, is placed on the arc shaft by gum cover and forms.On arc shaft, be nested with the more piece roller continuously, roller is connected on the arc shaft by rolling bearing; Also be equipped with on the arc shaft two ends and connect cover, connect cover and join with ring washer with roller, hole respectively; Two connect and put and be equipped with respectively the roller shell, and roller shell one end links to each other with gum cover; Hole ring washer, plug screw and water proof ring, oil seal cover are housed respectively on axle sleeve.The roller shell equates that with the external diameter of gum cover is concentric its outer peripheral face at grade.
The utility model leaves certain clearance owing on arc shaft, be nested with the more piece roller continuously between each roller, this version can reach the required any arc line style of bowed roller, and the bowed roller good rigidly, when work, not yielding, can keep the arc of pre-designed bowed roller; The fabric width of paper machine can be brought up to more than 3150 millimeters by original 787-1092 millimeter.Roller is connected by rolling bearing with arc shaft, when web part of paper machine, woollen blanket, dried net, page etc., when on bowed roller, dragging the carrying row, gum cover and arc shaft are rolling friction, then resistance greatly reduces, so the speed of a motor vehicle can improve greatly, its speed of a motor vehicle by original 40-60 rice/minute, bring up to more than 1500 meters/minute.Roller shell and gum cover are equipped with the hole again with seals such as ring washer, plug screw, water proof ring and oil seal covers for closely to be connected on axle sleeve, make bowed roller exempt from the corrosion of pulp liquor.
The utility model compared with the prior art, its advantage: bowed roller is used for the paper machine of the high speed of a motor vehicle and wide format, bowed roller is indeformable, keep good arc, make it unfold polyester net, woollen blanket, dried net and page reliable assurance has been arranged, the papery of page is significantly improved, and has avoided " wrinkling ", " discounting " such as polyester net, woollen blanket, dried net, page; Reduce the loss, improved effectively economic benefit.Again not because of pulp liquor to the arc shaft corrosion, and need not often to change bowed roller, then increased the service life of bowed roller greatly.
The utility model can also be further specified from the following drawings and embodiment:
Fig. 1 the utility model front elevational schematic.
Fig. 2 is vertical cross-sectional schematic of Fig. 1.
Fig. 3 is Fig. 2 A place enlarged diagram.
Fig. 4 is Fig. 2 B place enlarged diagram.
Drawing numbering: the 1-arc shaft, 2-roller shell, the 3-gum cover, 4-axle ring washer, the 5-bearing, 6-connects cover, 7-O type circle, 8-hole ring washer, 9, the 14-axle sleeve, 10-plug screw, 11-oil seal cover, 12-screw, 13-roller.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
The utility model is a kind of bowed roller.On arc shaft 1, in the middle of this, first O type circle 7 is packed in the axle sleeve, again short sleeve 14 connecting shafts are held 5, join by the fixed position and drilled through screw 12, it is packed on the arc shaft 1; Fill the pad special greases in the bearing 5, the trade mark: 7014 lubricating grease, secondly, on the both sides of bearing 5, each suit one roller 13, then, equidistant one saves bearing 5 and roller 13 is installed along arc shaft 1 both sides, after installing to the edge, two ends, on more piece roller 13 peripheries, overlap a gum cover 3 again; On arc shaft 1 two ends, respectively put a major axis cover 9 and bearing 5 again; Install one additional in its outside and connect cover 6.Connect cover 6 one end end faces and roller 13 and join, cover spiral shell one roller shell 2 on the periphery of its other end, and the interior inclined-plane of roller shell 2 one end endoporus is pressed on the outer inclined-plane of gum cover 3 one end cylindricals; On major axis cover 9, be set with hole ring washer 8 and plug screw 10; The hole with ring washer 8 with connect cover 6 other end end faces and be abutted against, on major axis cover 9 and plug screw 10 the same side end faces, water proof ring and oil seal cover 11 are housed.
The utility model is contained in papermaking equipment wet end, press section, oven dry portion by two supporting bases supports and finishes on finishing device, coating apparatus and the sheet cut machine.Outside the spherical bearing shell in a supporting base, worm gear, the worm screw of one group of engagement arranged, worm gear links to each other with bowed roller one end, rotates when rotary worm can drive the bowed roller that worm gear is housed, and regulates this roller radian arbitrarily to reach from the 0-180 degree.As using this roller at wet ends such as polyester net, woollen blankets, be furnished with thickness on this roller shell is 10 millimeters folder cloth oil resistant gum cover, is sealed, and just guarantees that this roller normally uses in each procedure.
