End where 11 one end of section is set there are one pulley 30, and drawstring 40 bypasses pulley 30, to reduce the friction that drawstring 40 is subject to.
As shown in Figure 1, being in charge of for each oil suction unit is arranged side by side, and the wiper ring 50 of each oil suction unit is fixed on one
It rises, to when one of wiper ring 50 slides, all wiper rings 50 be driven to move together.As shown in Fig. 2, in air hose 10
Upside be equipped with reciprocator, reciprocator include motor, with 63 fixed crank 62 of motor output shaft and both ends respectively with
Crank 62 and the hinged connecting rod 61 of wiper ring 50, so that crank 62, connecting rod 61 and wiper ring 50 constitute 62 sliding block machine of crank
Structure；Therefore, when motor operation, crank 62 will drive wiper ring 50 to be moved back and forth on air hose 10；Meanwhile flabellum 20 will enter
It constantly rotates in mouth section 11, introduces the air-flow in milling train exit in air hose 10.
In addition, be also welded with wiping pipe 41 on 10 outer wall of air hose at pulley 30, the inner wall of wiping pipe 41 is equipped with the
Two spongy layers 42,40 son of drawstring pass through wiping pipe 41.The oiling oleophylic coating on the outer wall of air hose 10, the oleophylic in the present embodiment
Coating uses alkylbenzene coating.Oleophylic coating is conducive to adsorb mist of oil, and mist of oil condensed layer oil droplet is avoided to be dropped in aluminium
On foil, the quality of aluminium foil is impacted.The throat 12 of air hose 10 will be in wind when flabellum 20 rotates equipped with oil-sucking hole 14
Air-flow is formed in pipe 10, when air-flow enters throat 12 from entrance 11, due to the cross-sectional area smaller of throat 12, throat
12 pairs of air-flows have compression, so that flow velocity when air-flow passes through throat 12 is accelerated, then the pressure at throat 12 reduces,
So that air-flow by oil-sucking hole 14 into Gas inlet tube 10, with to not inhaled again by the mist of oil for the entrance 11 that flabellum 20 introduces
It receives.The diffuser 13 of air hose 10 is connected by hose in oil return box, is understood mist of oil in fuel tank, to be recycled to ROLLING OIL.
When being rolled to aluminium foil, start the motor operation of reciprocator, it is made to drive wiper ring 50 on air hose 10
It moves back and forth, then wiper ring 50 drives shaft 21 to rotate, so that flabellum 20 rotates forward.To which most of rolling oil mist will be by flabellum 20
It is sent into air hose 10；In addition, oil-sucking hole 14 will further absorb rolling oil mist, to increase the pumping to rolling oil mist
Energy-absorbing power；After rolling oil mist is inhaled into air hose 10, it will be discharged and be admitted in oil return box from the diffuser 13 of air hose 10, with right
ROLLING OIL is recycled.
During wiper ring 50 moves back and forth, the first spongy layer 52 will carry out the oil droplet being formed on 10 outer wall of air hose
Absorption；And when the first spongy layer 52 is by throat 12, oil-sucking hole 14 will generate adsorption capacity to the oil droplet being adsorbed in spongy layer,
It is dropped on aluminium foil to avoid rolling oil mist from forming oil droplet.When in order to avoid wiper ring 50 by oil-sucking hole 14, the first sponge
Negative pressure are formed in layer 52, lead to be unfavorable for the oil droplets being sucked out in spongy layer, set that there are six radial along wiper ring 50 on wiper ring 50
Through-hole 51, and through-hole 51 is uniformly distributed along the circumferential direction of wiper ring 50.As shown in figure 4, drawstring 40 will be relative to the second spongy layer
42 move back and forth, and to which the second spongy layer 42 will absorb the mist of oil being adsorbed on drawstring 40, avoid the shape on drawstring 40
It is dropped on aluminium foil at oil droplet.
ROLLING OIL oil droplet is dropped on aluminum foil plate surface, and the product surface produced will be caused to have the oily phenomenon of band, rolling
On the one hand the surface that oil is sticked to aluminium foil can cause the product user produced that can not use, reduce yield rate；And it is excessive
Band oil can also make that serious string layer phenomenon occurs batching the when of tightly wrapping, and cause to go here and there layer if it is in pony-roughing pass, can make finished product road
Not top is cut when secondary trimming, and causes aluminium foil broken belt.Therefore, dress is absorbed by adding mist of oil in the exit of aluminium foil hot-rolling mill
It sets, it is possible to reduce the band oil phenomenon of aluminium foil.
Above-described is only the embodiment of the present invention, and the common sense such as well known concrete structure and characteristic are not made herein in scheme
Excessive description.It, can be under the premise of not departing from present invention proportioning it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these should also be considered as protection scope of the present invention, these all do not interfere with what the present invention was implemented
Effect and patent practicability.The scope of protection required by this application should be based on the content of the claims, in specification
The records such as specific implementation mode can be used for explaining the content of claim.
