Description
Technical Field
The utility model belongs to the technical field of nonferrous metal processing equipment, and particularly relates to an outlet purging device of an aluminum foil mill.
Background
With the vigorous development of the packaging industry, aluminum foils with the thickness of less than 0.2mm are widely applied to packaging composite base materials in the industries of medicine, food, beverage, tobacco and the like. The aluminum foil package has: the packaging material has the characteristics of good sealing property, moisture resistance, no odor, low air permeability, difficult aging and the like, and is increasingly applied to the field of packaging. According to incomplete statistics, the yield of packaging aluminum foil in China is close to 200 ten thousand tons in 2020. The total consumption of domestic packaging is nearly 100 ten thousand tons, and the market prospect is wide.
At present, the production of aluminum foils at home and abroad usually adopts a 4-roller mill production process, rolling oil is used for lubrication in the rolling process, a layer of extremely thin oil film is adsorbed on the surface of the rolled aluminum foil, the rolled aluminum foil cannot be directly used for packaging food, medicines, cigarettes and the like, and the quality requirements on sanitation, safety and packaging plasticity are not met.
Aluminum foils applied to packaging are usually cut and annealed at a certain temperature to remove oil, so that the aluminum foils with certain plasticity and clean surfaces can be used for packaging materials.
Modern rolling mills are usually 4-roll mills, and a 4-roll system is composed of an upper supporting roll, a lower supporting roll, an upper working roll and a lower working roll. The aluminum foil is fed into the roll gap of the working roll through the inlet, and the aluminum foil reaches the target thickness under the effect of large rolling force and speed. The aluminum foil rolling belongs to the rolling without a roll gap, the oil carried by the aluminum foil just after the roll gap is formed is almost negligible, the oil carried by the surface of the aluminum foil is mainly derived from the oil carried by the surface of a supporting roll when the supporting roll runs at a high speed, when the supporting roll rotates to the occlusion part of an outlet side and a working roll, the oil carried by the supporting roll can be extruded out at the roll gap part of the supporting roll and the working roll under the action of the large pressure without the roll gap, the thin flow of rolling oil is formed and thrown to the aluminum foil rolling direction, if an oil blocking purging measure is not adopted, a large amount of oil is carried on the surface of the aluminum foil, the surface quality of the aluminum foil is seriously influenced, even unqualified products such as oil spots, unclean annealing and the like are formed after the aluminum foil is annealed.
Therefore, the defects of the prior art are necessarily combined, and the outlet purging device of the aluminum foil rolling mill is designed to perform targeted purging on oil on the surface of the aluminum foil, so that the product quality is improved, and the production cost is saved.
Disclosure of Invention
In view of the above-mentioned deficiencies in the prior art, the present invention provides an outlet purging device for an aluminum foil rolling mill, which reduces the influence on the oil on the outlet surface by two aspects: 1. the oil quantity of the entrainment on the surface of the supporting roll is reduced, which is equivalent to the reduction of the oil extrusion quantity at the contact roll gap between the working roll and the supporting roll; 2. the surface of the supporting roller is enhanced to be blown, and oil carried on the supporting roller is blown and gasified through air, so that the extruded oil is prevented from falling on the charge level to form oil.
According to the principle, most of rolling oil on the supporting roller is scraped by a polyester scraper, and the rolling oil brought to the outlet side along with the roller clamp is gasified by two fan-shaped air nozzles and blown away to the two sides of the roller, so that the rolling oil is prevented from forming oil spots and falling onto the charge surface; meanwhile, the arc-shaped sliding rail baffle on the outlet side is equivalent to an oil groove, most of the blown rolling oil is thrown onto the baffle, and the grooves in the bottom of the baffle are converged and then flow out from two sides. Not only can improve the product quality, but also can save the production cost.
The utility model provides an outlet blowing device of an aluminum foil mill, which is formed by reforming the prior supporting roll and the prior working roll and comprises a roll cleaner and a blowing device,
the roller cleaner comprises: flexible scraping blades distributed in a splayed shape, a bracket for mounting the scraping blades, an air cylinder for driving the bracket to ascend and contract, and a pressure regulating valve,
the purging device includes: the outlet arc-shaped sliding plate, the supporting roller blowing air nozzle and the roller gap blowing air nozzle which are arranged on the outlet arc-shaped sliding plate and the adjusting screw rod for adjusting the directions of the two air nozzles are arranged.
In a better disclosed embodiment of the utility model, the flexible scraping blades distributed in a splayed manner in the roller cleaner are integrated polyurethane scraping blades with the hardness of 60-75 HS Shore hardness.
In the preferred embodiment of the utility model, the shapes of the supporting roll blowing air nozzles and the roll gap blowing air nozzles are fan-shaped air nozzles, and the widths of the supporting roll blowing air nozzles and the roll gap blowing air nozzles are matched with the width of the roll surface and are 5-15% of the width of the roll surface of the rolling mill, preferably 10%.
In the better disclosed embodiment of the utility model, the air nozzles of the supporting roll blowing air nozzle and the roll gap blowing air nozzle are arc flat nozzles, and the openings at two sides are larger than the opening in the middle, so that more air quantity is blown to two sides.
Most of oil on the lower roller is mainly scraped off by the roller cleaner, and the oil extruded from the roller gap falls under the dead weight, so that the oil on the lower surface of the aluminum foil is not polluted.
The shapes of the supporting roller blowing air nozzle and the roll gap blowing air nozzle adopt fan shapes, the opening of the fan-shaped air nozzle adopts a shape which is flat in the middle and gradually expands towards two outer sides, the wind power and the air quantity of two sides are enhanced, the diffusion of oil gas towards two sides is facilitated, and the chance of oil gas accumulation and material dropping surface is reduced.
The technical steps are simple and practical, and the oil on the material surface of the outlet side can be effectively blocked and blown.
Advantageous effects
The aluminum foil mill outlet purging device is simple and practical in structure, and the rolling oil is purged completely by the purging mode of the roller cleaner and the supporting roller purging tuyere, so that the oil on the surface of the material is prevented; the adopted air nozzle is designed in a fan shape, and the opening of the air nozzle is flat in the middle and gradually enlarged towards two sides, so that gasified oil gas is favorably diffused towards two outer sides, and the oil gas is prevented from being condensed again and dropping on a rolling material surface to form oil carrying; the double fan-shaped air nozzles are adopted, so that the problem that when the air nozzles are used independently, the air quantity is too large to form a cooling effect on the roll shape of the working roll, the upper working roll is interfered by air quantity regulation, and the adverse effect on the shape of an aluminum foil plate is caused is avoided, and when the air quantity is too small, the effect of preventing the surface of the aluminum foil from being oiled can not be achieved; the double air nozzles are adopted, so that the purging of the supporting roller can be enhanced by increasing the air quantity of the air nozzles, the influence of the large air quantity of the air nozzles 7 in a roller gap area on the roller shape of the working roller is reduced, and the stability of the shape of the aluminum foil is facilitated; the worm is independently adjusted in the direction of the double fan-shaped air nozzles, and is used for adjusting the air directions of respective blowing areas of the air nozzles, so that the blowing effect is exerted to the maximum extent.
