[0037] A groove 29 is provided on the inner wall of the placement groove 6, and a clamping block 30 is slidably connected inside the groove 29. A threaded rod 31 is threadedly connected to the right side wall of the workbench 1. The end of the threaded rod 31 located inside the groove 29 is rotatably connected to the clamping block 30, and the end of the threaded rod 31 located outside the workbench 1 is fixedly connected to a screw block. The rotation of the threaded rod 31 is controlled by the screw block, and then the movement of the clamping block 30 is controlled. When the screw block rotates forward, the clamping block 30 clamps the mixing barrel 7, and conversely, the clamping block 30 loosens the mixing barrel 7. The side of the clamping block 30 close to the placement groove 6 is arc-shaped, and a rubber pad is provided on the arc-shaped surface of the clamping block 30. A control box 32 is provided on the top of the workbench 1, and the electric cylinder 2 and the stirring motor 4 are electrically connected to the control box 32.

[0038] There are two fixing rods 9, connecting plates 10, mounting grooves 12 and observation glasses 13, which are symmetrically arranged on the left and right sides of the cover plate 11. The bottom end of the observation glass 13 is flush with the bottom end of the cover plate 11. There are two mounting seats 15, slots 16 and cleaning blocks 17, which are symmetrically arranged on both sides of the rotating shaft 5.

Each receiving plate 22 is internally provided with two movable cavities 26, two limit blocks 27 and two limit rods 28.

[0039] Working principle: When in use, first put the mixing barrel 7 into the placement groove 6, then rotate the screw block forward to make the clamping block 30 clamp the mixing barrel 7, and then add some raw materials for making polyurethane polymer coating into the mixing barrel 7 first. After the addition is completed, the electric cylinder 2 is controlled by the control box 32 to work, and the electric cylinder 2 controls the horizontal plate 3 to move downward. At the same time, the material receiving plate 22 is pulled into the storage cavity 21 through the pulling block 24. When the stirring rod 8 enters the interior of the mixing barrel 7, the pulling block 24 is released. When the cover plate 11 covers the mixing barrel 7, the electric cylinder 2 stops working. At this time, the stirring motor 4 controls the rotating shaft 5 to drive the stirring rod 8 to rotate. At the same time, the cleaning block 17 rotates under the action of the rotating shaft 5 and cleans the observation glass 13. When different raw materials need to be added in the middle, the control box 32 controls the stirring motor 4 to stop working, and at the same time, the control box 32 controls the electric cylinder 2 to work, and the electric cylinder 2 controls the cover 11 to move up and open the stirring barrel 7. At this time, the stirring rod 8 is still inside the stirring barrel 7. After the raw materials are added, the electric cylinder 2 controls the cover 11 again to cover the stirring barrel 7, and then the stirring motor 4 controls the stirring rod 8 to continue stirring. When the paint is manufactured, the stirring motor 4 stops working, and the electric cylinder 2 controls the stirring rod 8 to move up. When the stirring rod 8 is removed from the inside of the stirring barrel 7, the receiving plate 22 automatically moves to the bottom of the stirring rod 8 under the action of the spring 25 to prevent the paint from dripping onto the workbench 1. Finally, the stirring barrel 7 can be taken out.
