Abstract
The utility model relates to a vacuum support roller with a novel structure. The vacuum support roller is made of a polyurethane material; through holes and groove patterns are formed in the vacuum support roller; the groove patterns form a spiral groove in the roller surface of the vacuum support roller. Compared with the prior art, the dryness of a page sheet press outlet area is improved, the steam consumption needed by subsequent drying is effectively reduced, the production cost is reduced, the water pressure in a press area is reduced, crushing or print dents of a paper sheet can be effectively prevented, the service life of coarse cotton cloth is prolonged, the aperture ratio is increased and the water content of the paper sheet scroll is more uniform.
Description
Technical field
The utility model relates to a kind of vacuum carrying roller, especially relates to a kind of vacuum carrying roller of new structure.
Background technology
Structure and the suction couch roll of suction press roll are similar, but have some different.It is narrower that the vacuum chamber width of suction press roll is wanted, and is generally 100～125mm; The diameter of suction press roll roll surface aperture is less, is 4.5mm left and right.Roll surface percent opening is lower, require high especially to the diameter of aperture simultaneously, when the diameter of aperture is larger, be positioned at the pressure that aperture place paper web is subject to less, web moisture is higher, easily on paper web, cause the distinctive hole of suction press trace (meet light while seeing, have the ` spot corresponding with aperture position in paper web).Suction press can be sloughed more water from l Water Paper, can improve paper delivery mass dryness fraction compared with plain press; Paper web is less conquassation also; More even along dehydration on banner width; Woollen blanket can keep stable kilter.But suction press also has its distinctive shortcoming, percent opening height after, can make roll body remitted its fury, it is complicated that structure becomes, and causes power consumption to strengthen because needs vacuumize, and produces noise pollution, to there is hole trace on some paper kind paper.For example, use the vacuum furnace of KAWONOE paper machine to adopt compound polyurethane material, use through hole dewatering type (percent opening approximately 30%), nip hydraulic pressure is higher, causes generation impression.Can reduce the service life of felt, and the mass dryness fraction of outgoing nip page is on the low side simultaneously, improves ton paper steam use amount, directly cause the increase of production cost, cannot realize energy consumption efficiency and maximize.
Utility model content
The purpose of this utility model be exactly provide a kind of in order to overcome the defect that above-mentioned prior art exists and can reduce costs, the page banner moisture vacuum carrying roller of new structure more uniformly.
The purpose of this utility model can be achieved through the following technical solutions:
A vacuum carrying roller for new structure, makes for polyurethane material the vacuum carrying roller obtaining, and on vacuum carrying roller, offers through hole, also offers rill on vacuum carrying roller, and described rill forms spiral groove on the roll surface of vacuum carrying roller.
Described spiral groove provides passing away for the moisture in nip.
Percent opening on described vacuum carrying roller is 45%.
Described through hole is that aperture is the through hole of 3-4mm, and as preferred embodiment, the aperture of through hole can be 3.5mm.
The width of described rill is 0.5-1.0mm, and the degree of depth is 2-3mm, and as preferred embodiment, the width of rill is 0.6mm, and the degree of depth is 2.5mm.
Compared with prior art, the utlity model has following advantage:
(1) improve the mass dryness fraction of page outgoing nip, can effectively reduce the steam consumption quantity of follow-up baking needed, production cost reduces, according to the energy consumption rule of paper machine, the every raising 1% of the mass dryness fraction of outgoing nip page, the consumption of steam can reduce 5-8%, as paper machine equipment conditions permit, can improve the speed of a motor vehicle.
(2) polyurethane wear resistant all will double above than best rubber, improves milling cycle more than a times.
(3) nip hydraulic pressure reduces, and can effectively prevent page conquassation or produce impression, extends the felt life-span simultaneously.
(4) percent opening strengthens, and page banner moisture is more even.
(5) improve paper machine operation performance, reduce disconnected paper.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing on this vacuum carrying roller surface.。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
A kind of vacuum carrying roller of new structure, its structure as shown in Figure 1, adopting polyurethane material to make obtains, on vacuum carrying roller, offer through hole 1, on vacuum carrying roller, also offer in addition rill 2, rill forms spiral groove on the roll surface of vacuum carrying roller, thereby can provide passing away for the moisture in nip.The aperture of through hole 1 can be 3-4mm, in the present embodiment, the aperture of through hole 1 is 3.5mm, the width of rill 2 is 0.5-1.0mm, the degree of depth is 2-3mm, and in the present embodiment, the width of rill 2 is 0.6mm, the degree of depth is 2.5mm, utilizes perforate and groove to make percent opening on vacuum carrying roller be increased to 45% by original 30%.
Increase percent opening and ensure that the dehydration of paper is even, operational excellence. and the moisture of paper is more even, and steam saving 4% left and right, because the roll surface of vacuum carrying roller has very fine and closely woven, spiral groove, these grooves provide the passage of discharging for the moisture in nip.Groove makes the below of nip communicate with atmosphere, and the moisture content in nip can be along vertical or enter groove close to vertical direction through woollen blanket.Moisture distance of required transverse shifting in woollen blanket is not more than the half of rill spacing, and flow resistance is less, makes the draining of nip have more satisfactory condition, and this is the main cause that increase rill final vacuum carrying roller has higher dehydrating function.
Claims (7)
