The invention relates to an automatic paint spraying device, and belongs to the technical field of automatic equipment. The automatic paint spraying device is characterized in that a spray gun is installed on a horizontal moving mechanism (3), the horizontal moving mechanism (3) is installed on a linear pushing mechanism (5), the linear pushing mechanism (5) pushes the horizontal moving mechanism (3) to ascend and descend or longitudinally move in the horizontal plane, and the horizontal moving mechanism (3) drives the spray gun to transversely move in the horizontal plane; and the linear pushing mechanism (5) comprises a first swing arm (7), a second swing arm (14), a horizontal moving mechanism installing arm (16) and a power mechanism, the power mechanism is connected with the first swing arm (7) and the second swing arm (14), and the horizontal moving mechanism installing arm (16) is connected with a swinging adjusting mechanism used for enabling the axis of the horizontal moving mechanism installing arm (16) to be kept parallel in the moving process. The automatic paint spraying device is compact in structure, the second swing arm can swing within the range of 360 degrees, the operation area is increased, the automatic paint spraying device can be folded during storing, the occupied space is small, and moving is convenient.

The invention provides a production method for treating weathering steel for containers without sand blasting or shot blasting. The production method adopts the following hot rolling process flow: heating with a heating furnace, rough rolling, finish rolling, laminar cooling, coiling, air blast cooling, insulating with an insulation cover and finishing. The production method is characterized in that the initial rolling temperature of a finishing mill is controlled between 950 DEG C and 1020 DEG C, the finishing rolling temperature is controlled between 850 DEC C and 900 DEC C, the rolling speed is more than 5.5m / s and each finish rolling stand adopts lubricating rolling; the surface roughness Ra of the roller of the stand at the tail of the finishing mill is controlled between 0.8mu m and 2.4mu m; front-section rapid cooling is adopted on the laminar cooling stage, the cooling water is controlled to be alkalescent and the PH value is 7.0-10; the coiling temperature is controlled between 550 DEG C and 620 DEG C; the steel coil after coiling is put in the ventilative and convective place or a fan is adopted to improve ventilation and convection to cool the steel coil to 460-500 DEG C at a speed of 2-5 DEG C / min; then the steel coil is put into the insulation cover to be insulated, is taken out after the temperature drops to 200+ / -20 DEG C and is naturally cooled to the room temperature; and the chemical component Si of the adopted slab is controlled between 0.20% and 0.25%.

A preparation process of a magnesium alloy chemical conversion coating, the process comprises the following steps: a, using a sodium hydroxide solution or a mixed solution of one or more of sodium phosphate, sodium carbonate and sodium silicate solution containing sodium hydroxide on the Magnesium or magnesium alloy is degreased; b. The degreased magnesium or magnesium alloy is pickled with a mixed solution of phosphoric acid and sodium phosphate; c. The pickled magnesium is treated with a mixed solution of hydrofluoric acid and sodium phosphate. or magnesium alloy for activation treatment; d, use a mixed solution of calcium nitrate hexahydrate, sodium nitrite, sodium iodide, hydrogen peroxide to carry out chemical conversion treatment on activated magnesium or magnesium alloy; e, use deionized water to chemical conversion treatment Magnesium or magnesium alloy for sealing. Because the present invention does not contain chromium compounds in the treatment liquid, it eliminates possible harm to the environment caused by toxic substances. The invention also has the characteristics of simple process and operation method, low cost, suitable for batch production and the like.

A paint spraying device comprises a paint spraying frame. A first slide and push groove with a through opening facing downwards is formed in the paint spraying frame. A first slide and push frame is installed in the first slide and push groove in the manner that the first slide and push frame can move up and down. Second slide and push grooves with through openings facing downwards are formed in the first slide and push frame in a left-right corresponding manner, wherein the second slide and push grooves extend in the front-back direction. Guiding and conveying grooves extending in the front-back direction are formed in the upper ends of the two side walls of each second slide and push groove. Second slide and push frames are installed in the second slide and push grooves in the manner that the second slide and push frames can move forwards and backwards. Atomization spray nozzles are fixedly installed at the lower ends of the second slide and push frames. Guiding and conveying blocks movably installed in the corresponding guiding and conveying grooves are correspondingly arranged on the left side and the right side of each second slide and push frame. Containing cavities extending in the front-back direction are formed in the second slide and push frames. Upper toothed chains are fixedly arranged in the upper end walls of the containing cavities. Lower toothed chains are fixedly arranged in the lower end walls of the containing cavities. An arrangement groove is further formed in the first slide and push frame. A second toothed chain wheel is movably installed in the arrangement groove through a second rotating rod. A first toothed chain wheel matched with the second toothed chain wheel is further movably installed in the arrangement groove through a first rotating rod.
