Abstract

The utility model relates to a roller cleaning machine component used in metal sheet mill equipment and particularly provides an oil squeezing roller type roller cleaning machine for an aluminium foil mill. The utility model is characterized in that the oil squeezing roller type roller cleaning machine for the aluminium foil mill comprises an oil squeezing roller and a bearing plate; the oil squeezing roller is fixedly connected with the bearing plate; the bearing plate is connected with an air cylinder; the air cylinder pushes the bearing plate to work; the oil squeezing roller comprises a roller sleeve, roller shaft heads and bearings; the outside of the roller sleeve is provided with a polyurethane mold casting layer; steps are turned on both sides of the roller sleeve; the roller shaft heads are welded on the steps; vent holes are drilled on the roller shaft heads; the bearings are arranged on the roller shaft heads; and the positions of inner rings of the bearings are provided with retaining rings for shafts. By replacing a scraper with the oil squeezing roller, the oil squeezing roller type roller cleaning machine improves the surface quality of an aluminium foil, reduces friction on the roller surface of a bearing roller so as to correspondingly weaken the wear condition of a working roll, reduces times of frequently replacing the working roll and the bearing roller and reduces the production cost. The oil squeezing roller type roller cleaning machine is also suitable for a cold-rolling mill in the aluminium rolling industry.

Description

Aluminium foil mill squeezes oiling roller formula roller-cleaning device

Technical field

The utility model relates to a kind of roller-cleaning device parts that are used for the sheet metal milling equipment, especially provides a kind of aluminium foil mill to squeeze oiling roller formula roller-cleaning device.

Background technology

Roller-cleaning device is the parts of high speed aluminium foil mill inside, and its effect is to remove attached to technical oil on two backing rolls and aluminium bits, prevents that technical oil is thrown on the aluminium foil surface of rolling outlet with roller, makes and is not with oil on the sheet material in the calendering.Current, aluminium sheet foil mill roller-cleaning device mainly is (as shown in Figure 4) of scraper-type, and single scraper plate is arranged, and (two scraper plates are splayed and install) of Double-scraper also arranged, and vane material generally is rubber or polyurethane.Scraper plate on the roller-cleaning device directly is pressed against on the surface of backing roll up and down under the effect of cylinder, when finishing the technical oil that stops splash, because its effect of friction relatively, the fineness on milling train surface has been caused destruction.And scraper plate is very big to the product surface quality influence to the pressure of roll surface: pressure is little, can cause the band oil of product surface; Pressure is big, and oil condition will appear not having in the backing roll surface, thereby black line occurs, is transferred on the working roll again, and the problem of the roller that occurs frequently changing jobs has increased production cost greatly.Just often, produce when the dust in the technical oil, grounds travel, broken belt field trashes such as aluminium bits be clipped between the scraper plate and backing roll of roller-cleaning device, gloss uneven and bright line problem can appear, influenced the quality of product surface.

Summary of the invention

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of aluminium foil mill to squeeze oiling roller formula roller-cleaning device, can improve the aluminium foil surface quality, reduce the friction to work backing roll roll surface, reduce production costs.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of aluminium foil mill squeezes oiling roller formula roller-cleaning device, it is characterized in that: comprise and squeeze oiling roller and support plate, squeeze oiling roller and be connected with support plate, connect a cylinder on the support plate.

Described crowded oiling roller comprises roller shell, roll shaft head and bearing, and the roller shell outside has the polyurethane mould to annotate layer, and the equal car in roller shell both sides has step, be welded with the roll shaft head on the step, be drilled with steam vent on the roll shaft head, bearing is installed on the roll shaft head, and the bearing inner race place is equipped with shaft block ring.Wherein, squeeze the oiling roller diameter more than 150mm, the polyurethane mould is annotated more than the monolateral thick 12mm of layer, more than shore hardness 70 degree, squeezes the length that oiling roller roll surface length is greater than backing roll straight line roll surface, and bearings mounted limit speed is greater than 12000/rmin on the roll shaft head ^-1, for the heat of crowded oiling roller bearing inside is in time distributed, the two ends of bearing do not add dust cap, only need at two bearings inner ring place axle to be installed and get final product with ring washer.

Operation principle:

Rely on the crowded oiling roller passive rotation of backing roll, contact with the supporting roll surface though squeeze oiling roller, in rotation in opposite directions, both sides do not produce friction mutually; Common bearing against in the process, the technical oil of institute's splash also can't be crossed compressive plane between them on the roll surface separately, can finish the work of squeezing the clear roller of oil like this.

The beneficial effect that the utility model had is: provide a kind of aluminium foil mill to squeeze oiling roller formula roller-cleaning device, by scraper plate being replaced with crowded oiling roller, improved the surface quality of aluminium foil, reduced friction to the backing roll roll surface, the abrasion condition of working roll also can correspondingly weaken, reduce the number of times of grinding replacing working roll and backing roll, reduced production cost.

Among the figure: 1, squeeze oiling roller; 2, support plate; 3, cylinder; 4, roller shell; 5, roll shaft head; 6, bearing; 7, the polyurethane mould is annotated layer; 8, steam vent; 9, shaft block ring; 10, backing roll; 11, working roll.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

As shown in Figure 1, a kind of aluminium foil mill squeezes oiling roller formula roller-cleaning device, comprises squeezing oiling roller 1 and support plate 2, squeezes oiling roller 1 and fixedlys connected with support plate 2, connects a cylinder 3 on the support plate 2, promotes support plate 2 work by cylinder 3.As shown in Figure 2, squeeze oiling roller 1 and comprise roller shell 4, roll shaft head 5 and bearing 6, roller shell 4 outsides have the polyurethane mould to annotate layer 7, the equal car in roller shell 4 both sides has step, is welded with roll shaft head 5 on the step, is drilled with steam vent 8 on the roll shaft head 5, bearing 6 is installed on the roll shaft head 5, and the bearing inner race place is equipped with shaft block ring 9.Wherein, squeeze the oiling roller diameter more than 150mm, the polyurethane mould is annotated more than the layer 7 monolateral thick 12mm, more than shore hardness 70 degree, crowded oiling roller 1 roll surface length is greater than the length of backing roll 10 straight line roll surfaces, and the limit speed of institute's installation bearing 6 is greater than 12000/rmin on the roll shaft head 5 ^-1, for the heat of crowded oiling roller 1 bearing 6 inside is in time distributed, the two ends of bearing 6 do not add dust cap, only need at two bearings inner ring place axle to be installed and get final product with ring washer 9.

Operation principle:

As shown in Figure 3, under backing roll 10 drives on one's own initiative, rely on crowded oiling roller 1 passive rotation of backing roll 10, contact with 10 of backing rolls though squeeze oiling roller 1, in rotation in opposite directions, both sides do not produce friction mutually; Common bearing against in the process, the technical oil of institute's splash also can't be crossed compressive plane between them on the roll surface separately, can finish the work of squeezing the clear roller of oil like this.
