In the embodiment of the utility model, the pre-degreasing device 4 comprises two pre-degreasing tanks 4.1 and a pre-degreasing tank passing rubber roll 4.2, and the pre-degreasing tank passing rubber roll 4.2 is arranged between the two pre-degreasing tanks 4.1. The first degreasing device 6 comprises two first degreasing tanks 6.1 and a first degreasing tank-passing rubber roll 6.2, wherein the first degreasing tank-passing rubber roll 6.2 is arranged between the two first degreasing tanks 6.1. The second degreasing device 8 comprises two second degreasing tanks 8.1 and a second degreasing tank-passing rubber roll 8.2, wherein the second degreasing tank-passing rubber roll 8.2 is arranged between the two second degreasing tanks 8.1. The washing device 10 comprises two washing tanks 10.1 and a washing tank passing rubber roller 10.2, wherein the washing tank passing rubber roller 10.2 is arranged between the two washing tanks 10.1. Two water washing tanks 10.1 are provided, one for tap water and one for deionized water.

The thickness of the aluminum plate is 0.012-0.15 mm, and the width of the produced plate is 1250m. The original column speed is 40 m/min. The production speed was rated at 40 m/min at a thickness of 0.03 mm. The thinnest aluminum foil of 0.012mm can be cleaned normally, and the defects of discounting, surface scratch and the like are avoided. The unreeling machine can manually adjust the tension in a single action state and an automatic state. The winding machine can manually adjust the tension in a single action state and an automatic state. The original equipment can normally clean the aluminum foil with the thickness of more than 0.03mm, and the ultra-thin aluminum foil can be cleaned as much as possible after the transformation, and the aluminum foil with the thickness of 0.012mm can be optimally cleaned. The line speed of the machine is referred to the original line speed, and the line speed is increased to 100 m/min as much as possible under the condition of permission.

Because the thickness of the aluminum foil is only 0.012-0.15 mm, the original machine cleaning roller cannot rotate when the tension is tiny, and the surface of the aluminum foil is scratched and broken, so that a synchronous power motor is added. After the synchronous power motor is added, corresponding equipment is added: motor frame, transmission shaft, coupling flange, advanced application converter, cable wire etc.. The production state of the aluminum foil with the thickness of 0.012mm is not considered in the unreeling, the tension and the reeling of the original machine, the situation of discounting lacing wires occurs when the aluminum foil is thinner, the problem of speed increase after the filtering is examined again, the speed reduction motor of the original configuration cannot be used, the speed reduction servo motor needs to be replaced, and the servo driver is newly applied in a high-grade mode.

The winding and unwinding tension of the original machine cannot be independently adjusted, the use is inconvenient, the operation mode is required to be changed, and the master control PLC control module is added and changed, including the man-machine interaction system, to be reprocessed. Because of cleaning the 0.012mm ultrathin aluminum foil, the original equipment lacks a corresponding deviation correcting device and a corresponding stretching roller device, and corresponding equipment is added in the improvement. Because the original cleaning roller has no reserved roller head, the roller with the synchronous motor needs to be added and the roller head needs to be modified.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
