By adopting the technical scheme, the rolling oil mechanism is arranged to reduce the rolling oil on the copper strip, so that the copper strip can be subjected to heat treatment subsequently.

Optionally, the rolling oil mechanism comprises an upper rolling oil component and a lower rolling oil component positioned below the upper rolling oil component;

the upper rolling oil assembly comprises an upper conveying belt, a plurality of upper sponges arranged on the upper conveying belt, an upper oil squeezing plate used for abutting against the upper sponges, and an upper oil groove arranged on the lower side of the upper oil squeezing plate, and the upper oil squeezing plate is positioned on one side, close to the rolling mechanism, of the upper conveying belt;

the lower rolling oil assembly comprises a lower conveying belt, a plurality of lower sponges arranged on the lower conveying belt and a lower oil squeezing plate which is used for being in conflict with the lower sponges, and the lower oil squeezing plate is arranged on one side, far away from the rolling mechanism, of the lower conveying belt.

By adopting the technical scheme, after the copper strip is rolled and moved out of the rolling mechanism, the copper strip passes through between the upper rolling oil component and the lower rolling oil component. The upper conveyor belt drives the upper sponge to move, and the lower conveyor belt drives the lower sponge to move, so that rolling oil on the copper belt is wiped. After the upper sponge absorbs rolling oil and moves to be pressed against the upper oil squeezing plate, the upper sponge is compressed, the rolling oil in the upper sponge seeps out and drops downwards, and the upper oil groove is used for receiving the upper oil squeezing plate and the rolling oil falling from the upper sponge. Similarly, the rolling oil in the lower sponge is discharged from the lower sponge after being extruded by the lower extrusion plate. So make go up sponge and lower sponge and can clean the deoiling to the copper strips continuously, and go up the oil groove and can retrieve rolling oil, effectively saved the consumption of rolling oil.

Optionally, the rolling oil mechanism and the transmission winding mechanism are both provided with two groups and are symmetrically arranged, the two transmission winding mechanisms are respectively arranged at two sides of the rolling mechanism, and the two rolling oil mechanisms are respectively arranged at two sides of the rolling mechanism.

By adopting the technical scheme, the rolling mill can perform forward rolling and reverse rolling by arranging the two groups of rolling oil mechanisms and the two groups of transmission rolling mechanisms, and simultaneously can perform forward oil removal and reverse oil removal, so that the rolling efficiency of the copper strip is effectively improved.

Optionally, go up rolling oil subassembly still includes the oiling roller, the oiling roller rotates to set up on last oil groove, just the tip of oiling roller stretches into in the supreme oil groove, the oiling roller is located the one side that the rolling mechanism was kept away from to the crowded oil board of going up, be provided with a plurality of blades that are used for going up the sponge conflict on the circumference lateral wall of oiling roller, be provided with the last communicating pipe of two last oil grooves of intercommunication on the last oil groove.

Through adopting above-mentioned technical scheme, go up when the sponge removes the blade conflict, drive the blade and rotate, drive the roller rotation of going up through the blade, the blade takes up the rolling oil in the oil groove and pours on the upper sponge. Meanwhile, when the upper sponge is in contact with the blades, rolling oil between the two blades can be sucked. The rolling oil can be supplemented to the upper sponge by the arrangement. Because the oiling roller is positioned on one side of the upper oil squeezing plate far away from the rolling mechanism, the upper sponge positioned on the copper strip side of the rolling mechanism is firstly abutted against the upper oil squeezing plate for compression and then is abutted against the blade, and finally is contacted with the copper strip, so that the rolling oil can be fully absorbed and then coated on the copper strip. The upper sponge positioned on the copper strip outlet side of the rolling mechanism is firstly abutted against the blades, then is contacted with the upper oil squeezing plate, and finally is contacted with the copper strip, and the upper sponge can fully discharge rolling oil and then absorb the rolling oil on the copper strip.

So set up, according to the difference of transmission direction, change the transmission direction of last conveyer belt in the last rolling oil subassembly, can realize the conversion of oiling, deoiling function, greatly improved the utilization ratio of going up the rolling oil subassembly for need not to additionally set up the oiling device that is located the top.

Optionally, the blade is the slope setting, when the roll that oils is located the copper strips side that advances of rolling mechanism, the one end that the blade is close to the roll that oils and the one end that the blade is kept away from the roll that oils are arranged along the direction of rotation of roll that oils.

Through adopting above-mentioned technical scheme, during the oiling, go up the sponge and remove along the direction of last crowded oiled board to the oiled board, go up the sponge and support and press on the blade in order to make the reverse rotation of oiling roller. Because the one end that the blade is close to the oiling roller and the one end that the blade is kept away from the oiling roller are arranged along the direction of rotation of oiling roller when the oiling roller is located the copper strips side of advancing of rolling mechanism, have restricted the rolling oil outflow that carries between two blades, improve the efficiency that the blade transmitted rolling oil to the quantity of absorbing rolling oil in the sponge has been improved when oiling, has improved the oiling effect.

Optionally, the lower rolling oil assembly includes a lower oil sump, which is located below the lower oil squeeze plate.

Through adopting above-mentioned technical scheme, through addding down the oil groove to accept the rolling oil of sponge extrusion down and the rolling oil on the lower crowded oily board down, thereby retrieve the rolling oil that is located the copper strips downside, further saved the consumption of rolling oil.

Optionally, the lower oil groove is located the below of conveyer belt down and is used for supplying down the sponge to stretch into, be provided with the communicating pipe down of two lower oil grooves of intercommunication on the lower oil groove.

Through adopting above-mentioned technical scheme, the in-process that the lower sponge removed moves into down the oil groove to absorb the rolling oil in the oil groove down. In order to make the lower sponge fully contact with the copper strips, the rotation directions of the lower conveying belts of the lower rolling oil assemblies positioned at the two sides of the rolling mechanism are opposite. After the lower sponge of the lower rolling oil component positioned on the copper strip outlet side of the rolling mechanism absorbs rolling oil, the lower sponge moves to the position where the lower sponge is propped against the lower oil extruding plate, and the rolling oil carried by the lower sponge is discharged. And a lower sponge of a lower rolling oil component positioned near the copper strip side of the rolling mechanism absorbs rolling oil, moves to be in direct contact with the copper strip, and oils the copper strip.
