[0037] like Figure 2 and Figure 3 As shown, combined with Figure 4 As shown, the high-speed agitator 9 contains a premixing tank for mixing materials. The agitator 9 is provided with multiple inlet pipes 11, into which connecting pipes 8 are inserted and connected.

The two ends of the first rotating rod 17 are respectively fixedly welded to two adjacent connecting blocks 18. A baffle 16 is provided with cavities at both ends. The baffle 16 is rotatably connected to the first rotating rod 17. The torsion spring 10 is disposed in the cavity at the end of the baffle 16 and is fixedly sleeved on the first rotating rod 17. Its two ends are respectively fixedly welded to the baffle 16 and the first rotating rod 17. The sidewalls of the directional portion of the baffle 16 abut against the sidewalls of the connecting blocks 18. The four baffles 16 abut against each other to form a square shape, thereby blocking and sealing the inlet of the input tube 11. The connecting tube 8 is provided with a fixing member fixedly connected to the input tube 11. The fixing member is a fixed cover 19. The diameter of the fixing cover 19 is larger than that of the input tube 11. The fixing cover 19 is fixedly welded to the outer wall of the connecting tube 8 and has an interference fit with the sidewall of the port of the input tube 11. After the connecting pipe 8 is inserted into the input pipe 11 , the worker makes the fixing cover 19 interference fit on the connecting pipe 8 , thereby lowering the connecting pipe 8 to separate from the input pipe 11 .

[0039] like Figure 4 As shown, the connecting tube 8 is provided with a second switch assembly 15 for opening the second sealing cover 13. The second switch assembly 15 includes a second rotating rod 20, a gear 21, and a rack 22. A rotating groove is defined on the inner wall of the connecting tube 8, and the second rotating rod 20 is rotatably connected to the inner wall of the rotating groove. The second sealing cover 13 is fixedly mounted on the second rotating rod 20 and abuts the inner wall of the rotating groove.

[0041] like Figure 3 and Figure 4As shown, when the formula needs to be adjusted, the staff can add, reduce, or replace the connecting tube 8 to adjust the type and ratio of the materials, thereby increasing the flexibility of the production line and enabling the same set of equipment to meet the processing and production requirements of various types of coating products. Adapting to market changes. When the connecting tube 8 is inserted into the input tube 11, the end of the connecting tube 8 will abut against the baffle 16, and push the baffle 16 to overcome the torsion spring 10 and rotate downward, thereby opening the first sealing cover 12 and allowing the connecting tube 8 to be inserted into the input tube 11. At the same time, when the connecting tube 8 is inserted into the input tube 11, the abutment block 26 will abut against the connecting rod 25. The connecting rod 25 moves relative to the connecting tube 8 under the restriction of the abutment block 26. The movement of the connecting rod 25 drives the rack 22 to pull the spring to move. The movement of the rack 22 drives the gear 21 to rotate. The rotation of the gear 21 drives the second rotating rod 20 to rotate. The rotation of the second rotating rod 20 drives the second sealing cover 13 to open and abut against the inner wall of the rotating groove, thereby facilitating the transportation of materials. When the fixing cover 19 abuts against the port of the input pipe 11, the staff rotates the fixing cover 19 to fix the fixing cover 19 to the input pipe 11, thereby fixing the connecting pipe 8 and the input pipe 11, reducing the possibility of the connecting pipe 8 falling off when inputting materials.

[0042] like Figure 3 and Figure 4 As shown, when the staff removes the connection between the connecting pipe 8 and the input pipe 11, the staff first pulls out the fixed cover 19 from the connecting pipe 8, and then drives the connecting pipe 8 to move. When the connecting pipe 8 moves, the connecting rod 25 moves away from the abutment block 26, and the rack 22 moves under the elastic force of the spring and drives the gear 21 to rotate, thereby closing the second sealing cover 13. When the connecting pipe 8 is away from the baffle 16, the baffle 16 rotates under the action of the torsion spring 10 to close the first sealing cover 12.

[0043] like Figure 7As shown, the mixing device includes a mixing tank 28, in which a stirring rod 29 is rotatably arranged, a support plate 30 is fixedly welded to the middle of the stirring rod 29, and scrapers 31 are fixedly welded at both ends of the support plate 30, and the scrapers 31 are slidably connected to the inner wall of the mixing tank 28. Two sets of cleaning components 32 for cleaning the scrapers 31 and the support plate 30 are arranged in the mixing tank 28. Two groups of cleaning components 32 are symmetrically arranged along the stirring rod 29. The cleaning component 32 includes two scrapers 33, a screw rod 34, a scraper ring 35, a first turbine 36 and a first vortex rod 37. The scraper block 33 is U-shaped. The two scrapers 33 are slidably connected to the scraper 31 on both sides of the support plate 30 in the vertical direction. The screw rod 34 is passed through and rotatably connected to the support plate 30. The scraper block 33 is threadedly connected to the screw rod 34. The scraper ring 35 is slidably connected to the support plate 30 on one side of the stirring rod 29, and the scraper ring 35 is magnetic. The scraper rings 35 on both sides of the stirring rod 29 on the support plate 30 attract each other under the action of magnetism. When the support plate 30 rotates at high speed, the scraper ring 35 moves toward the scraper 31 under the action of centrifugal force, thereby cleaning the residual paint on the support plate 30.

[0044] like Figure 8 As shown, a placement groove 38 is opened in the support plate 30 along the horizontal direction, the first turbine 36 rotates in the end of the placement groove 38 and is fixedly sleeved on the screw 34, the first worm 37 rotates in the placement groove 38 and meshes with the first turbine 36, a drive rod is rotatably arranged in the placement groove 38, both ends of the drive rod are fixedly welded to the first worm, and a second turbine 39 is fixedly sleeved on the drive rod, an extension groove 40 is opened in the stirring rod 29 along the vertical direction, the extension groove 40 is communicated with the placement groove 38, a second worm is rotatably arranged in the extension groove 40, the second worm is meshed with the second turbine 39, the end of the second worm away from the second turbine 39 is penetrated by the stirring rod 29 and is fixedly connected to a micro motor 42, a bracket 43 is fixedly installed on the mixing tank 28, the micro motor 42 is fixedly installed on the bracket 43, and the bracket 43 is also provided with a power part for driving the stirring rod 29 to rotate.

[0045] like Figure 7 and Figure 8As shown, when the staff needs to change the color of the product, they first need to clean the mixing tank 28 by supplying clean water. Then, they start the stirring rod 29 to rotate. The rotation of the stirring rod 29 drives the scraper 31 to rotate, thereby cleaning the residual paint on the inner wall of the mixing tank 28, thereby reducing color contamination. When the stirring rod 29 rotates, the support plate 30 rotates along with it, thereby using centrifugal force to drive the scraper ring 35 to scrape and clean the paint from the side surface of the support plate 30. Subsequently, the micro motor 42 starts to drive the second worm to rotate. The rotation of the second worm drives the drive rod to rotate. The rotation of the drive rod drives the first worm through the second turbine 39 to rotate. The rotation of the first worm drives the first turbine 36 to rotate, thereby driving the screw 34 to rotate. The rotation of the screw 34 drives the scraper 33 to move along the scraper 31, thereby cleaning the residual paint on the surface of the scraper 31, reducing the color contamination of the new paint by the residual paint.
