[0007] The spray device comprises a hot water spray device and a cold water spray device.

[0008] The paint inlet of the double-sided coating machine is connected to the color coating feeding device, which includes a paint hose. The paint hose is connected to a suction straight pipe inserted into a paint bucket. A sensor is arranged on one side of the suction straight pipe. The sensor is arranged at the bottom of the suction straight pipe and is flush with the inlet of the suction straight pipe. The output end of the sensor is connected to a controller, and the output end of the controller is connected to an alarm.

[0009] A U-shaped pressure gauge is arranged on the curing oven shell.

[0010] Compared with the prior art, the high-strength antistatic thermal insulation color-coated plate processing equipment has the following beneficial effects: high-cleanliness degreasing is achieved by controlling the alkali point during pre-treatment, thus avoiding the quality defects of color bands on the plate surface during production; by setting the paint formula and controlling the use of stirring, the color steel plates produced are of better quality; at the same time, by closely observing and timely adjusting the drying oven pressure, the paint surface is stabilized and the quality of the color-coated plate is improved.
