The development of water-based industrial coatings is currently a good development opportunity and a future development trend. The key technology that affects the development of water-based industrial coatings is the research and development of water-based resins and high-purity ultrafine solid additives. In recent years, the progress and development of water-based resin production technology has made it possible for water-based coatings to gradually replace solvent-based coatings. Water-based nano coatings refer to coatings that use water as a dispersion medium. They have less organic solvent volatility, are pollution-free, safe and non-toxic. They are the mainstream direction of modern coating development. Obtaining high-performance and stable water-based nano coatings has very important application value.

Clamping: First, push a set of mixing barrels 8 onto the bottom plate 1 along the positioning groove 7 and stop them above the lifting plate 13. The first oil cylinder 11 extends and retracts the shaft to drive the support seat 4, the first drive box 6 and the second rotating shaft 29 to descend until the end of the second rotating shaft 29 away from the first drive box 6 is inserted into the mixing barrel 8. Then, the second oil cylinder 12 extends and retracts the shaft to drive the lifting plate 13 to rise, and then drives the mixing barrel 8 to rise until the fixing flange 17 of the outer wall of the mixing barrel 8 abuts against the corresponding end plate 16. The end plate 16 is fixed to the fixing flange 17 by screws. The first oil cylinder 11 and the second oil cylinder 12 extend their shafts, driving the lifting plate 13 and the first drive box 6 to separate. After the lifting plate 13 enters the sink 19 and the second oil cylinder 12 extends its shaft completely, the first motor 23 is started, and after the speed reduction by the reducer 24, the first drive box 6 is driven to turn over 180 degrees through the first gear 25 and the second gear 26, and the fixed set of mixing barrels 8 is turned over to the top of the first drive box 6, and then the front clamping action is repeated to fix the other set of mixing barrels 8 in place. S3, start stirring. After the two groups of stirring barrels 8 are fixed, start the first motor 23 and the second motor 27 at the same time. The first motor 23 drives the first drive box 6 to rotate in a regular pattern of one circle forward and one circle backward. The second motor 27 drives the second rotating shaft 29 and the multiple groups of stirring rods 28 to rotate, so as to stir the raw materials in the stirring barrel 8.

After the stirring is completed, the two groups of stirring barrels 8 are removed in sequence in the reverse order of the front clamping action to discharge the material, thereby completing the preparation of the water-based nano-metal coating.

[0023] Working principle: in the initial state, the lifting plate 13 is located inside the sink 19 and the upper surface is flush with the upper wall of the bottom plate 1. At this time, the positioning groove 7 on the lifting plate 13 is at the same level as the positioning groove 7 on the bottom plate 1, which is convenient for pushing the mixing barrel 8. The mixing barrel 8 can be pushed more conveniently by setting four sets of rollers 9. The positioning groove 7 is set to facilitate the alignment of the axis line of the mixing barrel 8 with the axis line of the second rotating shaft 29 in the left and right directions, so that the mixing barrel 8 does not interfere with the second rotating shaft 29 when it moves from the bottom plate 1. When loading and discharging, the support seat 4 is driven up by the first oil cylinder 11, and then the first drive box 6 and the second rotating shaft 29 are driven up. After the first oil cylinder 11 extends the shaft and rises to the upper stroke, the horizontal height of the lower end of the second rotating shaft 29 is higher than the upper end of the mixing barrel 8 located on the upper wall of the bottom plate 1. After the raw materials are loaded into the mixing barrel 8, it is pushed to the bottom plate 1 by the rollers 9 and stops on the lifting plate. 13, the second oil cylinder 12 extends the shaft and retracts it, driving the lifting plate 13 to rise, thereby lifting the mixing barrel 8, and driving the mixing barrel 8 to move toward the first driving box 6. When discharging, the lifting plate 13 is also used to carry the mixing barrel 8, which can effectively reduce the intensity of manual labor. Two sets of relatively arranged mixing barrels 8 are set. When the second motor 27 rotates, it can drive the second rotating shaft 29 to rotate, driving the stirring rods 28 at both ends of the second rotating shaft 29 to stir in the two sets of mixing barrels 8 respectively, effectively improving the production efficiency. While the stirring rods 28 are rotating and stirring, the first motor 23 drives the two sets of mixing barrels 8 to rotate back and forth around the axis of the first rotating shaft 5, thereby causing the raw material liquid inside the mixing barrel 8 to be driven to flow, further improving the flow path of the raw materials, and cooperating with the stirring action of multiple sets of stirring rods 28 to achieve multi-dimensional stirring motion, greatly improving the stirring effect.
