[0023] Please refer to Figures 1-4 , a coating machine for aluminum coils, including an elastic pressing device for elastically pressing and tensioning an aluminum strip, and further including a box device for pulling the aluminum strip to move vertically. A roll coating device for simultaneously roll-coating a coating liquid from both sides is arranged in the middle of the box device. There are two elastic pressing devices, which are evenly distributed up and down on one side of the box device.

[0024] In this embodiment: The box device includes a roll coating box 101. The roll coating box 101 is made of Q235 steel. A feed inlet 102 is arranged on one side of the roll coating box 101. A support roll 103 is arranged in the roll coating box 101. The support roll 103 is connected to the roll coating box 101 by bearings. A driving roll 104 is arranged above the support roll 103. A first motor 105 is arranged in front of the driving roll 104. The aluminum strip enters from the feed inlet 102 at the bottom of the roll coating box 101 and flows out from the top of the roll coating box 101. The first motor 105 drives the driving roll 104 to rotate to pull the aluminum strip vertically upward from the upper end, and the support roll 103 cooperates with the pressing roll 301 to pull and flatten the lower end of the aluminum strip;

[0025] In this embodiment: The roll coating device includes a roll coating pump 201. The roll coating pump 201 is bolted to the roll coating box 101. A filter head 202 is provided below the roll coating pump 201. The filter head 202 is connected to the roll coating pump 201 in a pluggable manner. A delivery pipe 203 is installed on the roll coating pump 201. Two equalizing pipes 204 are symmetrically arranged at the top of the delivery pipe 203. The delivery pipe 203 and the equalizing pipes 204 are welded together. Two coating rollers 205 are symmetrically installed inside the equalizing pipes 204. A second motor 206 is provided at the rear end of the coating roller 205. The second motor 206 is connected to the coating roller 205 by a flat key. The roll coating pump 201 extracts the coating liquid at the bottom of the roll coating box 101 through the filter head 202, delivers it to the equalizing pipes 204 through the delivery pipe 203 to apply the coating liquid on the surface of the coating rollers 205, and then drives the coating rollers 205 to rotate through the second motor 206 to perform coating simultaneously from both sides of the aluminum strip.

[0026] In this embodiment: The spring pressing device includes a pressing roller 301. Two limiting edges 302 are symmetrically arranged at both ends of the pressing roller 301. Two sliders 303 are symmetrically installed at both ends of the pressing roller 301. A sliding rod 304 is provided on one side of the slider 303.

The slider 303 and the sliding rod 304 are respectively slidably connected to the roll coating box 101. The roll coating box 101 supports the pressing spring 305 to push the slider 303 to drive the pressing roller 301 to move under the support of the sliding rod 304, and presses the aluminum strip against the driving roller 104 and the supporting roller 103 at the upper and lower ends respectively.

[0027] Working principle: The aluminum strip enters from the feed port 102 at the bottom of the roll coating box 101 and flows out from the top of the roll coating box 101. During this period, the roll coating box 101 supports the pressing spring 305 to push the slider 303 to drive the pressing roller 301 to move under the support of the sliding rod 304, and presses the aluminum strip against the driving roller 104 and the supporting roller 103 at the upper and lower ends respectively. The first motor 105 drives the driving roller 104 to rotate to pull the aluminum strip vertically upward from the upper end. The supporting roller 103 cooperates with the pressing roller 301 to pull and flatten the lower end of the aluminum strip. At the same time, the roll coating pump 201 extracts the coating liquid at the bottom of the roll coating box 101 through the filter head 202, delivers it to the equalizing pipes 204 through the delivery pipe 203 to apply the coating liquid on the surface of the coating rollers 205, and then drives the coating rollers 205 to rotate through the second motor 206 to perform coating simultaneously from both sides of the aluminum strip. Finally, the excess coating liquid flows downward back to the bottom of the roll coating box 101 for recycling.
