A stirring mechanism 8 is provided on the inner wall of the mixing cylinder 1. An arc-shaped groove 2 is penetrated through the outer wall of the mixing cylinder 1. A filter screen plate 4 is provided on the inner wall of the mixing cylinder 1. An arc-shaped support block 5 is fixedly installed on the outer wall of the filter screen plate 4. A handle 6 is fixedly installed on the outer wall of the arc-shaped support block 5. The arc-shaped support block 5 is matched with the arc-shaped groove 2. One end of the outer wall of the filter screen plate 4 is fixedly installed with a support plate 7. The support plate 7 movably penetrates through the inner wall of the mixing cylinder 1. Two vibration motors 3 are fixedly installed on the outer wall of the mixing cylinder 1.

[0023] The effect achieved by the entire Embodiment 1 is that the stirring mechanism 8 can stir and mix the powder coating. When the powder coating is stirred in the mixing cylinder 1, it will fall above the filter mesh plate 4. The filter mesh plate 4 will filter the powder coating, intercepting solid impurities in the powder coating, thereby improving the quality of the powder coating. At the same time, two vibration motors 3 can be turned on. The two vibration motors 3 generate vibrations at the filter mesh plate 4, causing the powder on the filter mesh plate 4 to vibrate, thereby increasing the filtering speed of the powder. When it is necessary to clean the impurities on the filter mesh plate 4, the grip 6 can be pulled to pull the filter mesh plate 4 out of the mixing cylinder 1, which facilitates the cleaning of the impurities on the filter mesh plate 4. At the same time, the support plate 7 and the arc-shaped support block 5 can support the filter mesh plate 4, enabling the filter mesh plate 4 to be stably placed on the inner wall of the mixing cylinder 1.

[0024] Embodiment 2 is as Figures 1-5 shown. The stirring mechanism 8 includes a top cover 801. A first motor 802 is fixedly installed at the top end of the top cover 801. The output end of the first motor 802 penetrates the top end of the top cover 801 and is fixedly installed with a rotating rod 803. A set of first stirring rods 804 is fixedly installed on the outer wall of the rotating rod 803. A rotating sleeve 805 is sleeved on the outer wall of the rotating rod 803. The rotating sleeve 805 is rotatably installed at the bottom end of the top cover 801. A first gear 806 is fixedly sleeved on the outer wall of the rotating sleeve 805. Two connecting rods 807 are fixedly installed on the outer wall of the rotating sleeve 805. A set of second stirring rods 809 is fixedly installed on the outer walls of the two connecting rods 807. The outer walls of the two scraping plates 808 are both fixedly installed with a set of second stirring rods 809. The two scraping plates 808 are both arranged in contact with the inner wall of the mixing cylinder 1. A second motor 810 is fixedly installed at the top end of the top cover 801. The output end of the second motor 810 penetrates the top end of the top cover 801 and is fixedly installed with a second gear 811. The second gear 811 is meshed with the first gear 806. The top end of the top cover 801 is fixedly communicated with a feed inlet 812. A sealing cover 813 is threadedly sleeved at the top end of the feed inlet 812. The bottom end of the mixing cylinder 1 is fixedly communicated with a discharge port 9. A discharge valve 10 is arranged at the output end of the discharge port 9. Three support columns 11 are fixedly installed at the bottom end of the mixing cylinder 1. The top cover 801 is fixedly connected to the mixing cylinder 1.

[0025] The effect achieved by the entire Embodiment 2 is that when it is necessary to mix powder coatings, different powder coatings are poured into the mixing cylinder 1 through the feed port 812, and the feed port 812 is sealed with the sealing cover 813 to prevent the dust generated during the mixing and stirring of the powder coatings from spreading out. Then, the first motor 802 is turned on, and the first motor 802 drives the rotating rod 803 to rotate. The rotating rod 803 then drives the first stirring rod 804 to rotate in the mixing cylinder 1, thereby stirring and mixing the powder coatings. At the same time, the second motor 810 can be turned on. The second motor 810 drives the second gear 811 to rotate. The second gear 811 then drives the first gear 806 to rotate. The first gear 806 can also drive the rotating sleeve 805 to rotate. The rotating sleeve 805 drives the scraper 808 to rotate in the mixing cylinder 1 through the connecting rod 807, thereby scraping off the powder adhering to the inner wall of the mixing cylinder 1. At the same time, the rotation direction of the second motor 810 is set so that the scraper 808 can drive the second stirring rod 809 to rotate in the opposite direction in the mixing cylinder 1 during the rotation process. Through the settings of the first stirring rod 804 and the second stirring rod 809, the mixing effect of the powder coatings is improved.

[0026] Working principle: When it is necessary to mix powder coatings, different powder coatings are poured into the mixing cylinder 1 through the feeding port 812. The feeding port 812 is sealed with a sealing cover 813 to prevent the dust generated during the mixing and stirring of the powder coatings from spreading out. Then, the first motor 802 is turned on. The first motor 802 drives the rotating rod 803 to rotate, and the rotating rod 803 further drives the first stirring rod 804 to rotate in the mixing cylinder 1, thereby stirring and mixing the powder coatings. At the same time, the second motor 810 can be turned on. The second motor 810 drives the second gear 811 to rotate, and the second gear 811 further drives the first gear 806 to rotate. The first gear 806 can also drive the rotating sleeve 805 to rotate. The rotating sleeve 805 drives the scraper 808 to rotate in the mixing cylinder 1 through the connecting rod 807, thereby scraping off the powder adhering to the inner wall of the mixing cylinder 1. At the same time, the rotation direction of the second motor 810 is set so that the scraper 808 can drive the second stirring rod 809 to rotate in the mixing cylinder 1 in the reverse direction during the rotation process. Through the settings of the first stirring rod 804 and the second stirring rod 809, the mixing effect of the powder coatings is improved. When the powder coatings are stirred in the mixing cylinder 1, they will fall above the filter mesh plate 4. The filter mesh plate 4 filters the powder coatings, intercepting solid impurities and the like in the powder coatings, thereby improving the quality of the powder coatings. At the same time, two vibration motors 3 can be turned on. The two vibration motors 3 generate vibrations at the filter mesh plate 4, causing the powder on the filter mesh plate 4 to vibrate, thereby improving the filtering speed of the powder. When it is necessary to clean the impurities on the filter mesh plate 4, the grip 6 can be pulled to pull the filter mesh plate 4 out of the mixing cylinder 1, thereby facilitating the cleaning of the impurities on the filter mesh plate 4. At the same time, the support plate 7 and the arc-shaped support block 5 can support the filter mesh plate 4, enabling the filter mesh plate 4 to be stably placed on the inner wall of the mixing cylinder 1. Then, the discharge valve 10 is opened to filter the mixed and filtered powder coatings.

[0027] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
