[0027] Compact structure: The ingenious combination of control components, mixing components, quantitative components and other structures makes the entire equipment compact, easy to operate, and improves work efficiency.

[0028] In the present invention, a dust cover plate 8 is hinged at one end of the feeding tube 2, a first handle 10 is fixedly connected to one side of the dust cover plate 8, and legs 6 are fixedly connected on all sides of the mixing barrel 1. Dust-proof design: the dust cover plate 8 is hinged at one end of the feeding tube 2, which effectively prevents contamination of the material and the entry of dust during the storage process, thereby ensuring the quality of the material.

[0029] Stable support: The legs 6 fixedly connected around the mixing barrel 1 provide stable support for the entire device, ensuring the stability and safety of the device during the mixing process.

[0030] Working principle: When electrostatic coating processing is required, the main raw materials are fed into the mixing barrel 1 through the feeding pipe 2, and a variety of different auxiliary materials are stored in different auxiliary material barrels 3 for adding during the mixing process. The size of the annular inner plate 53 can be adjusted according to the different amounts of auxiliary materials added, and the size of the internal space of the fixed barrel 44 can be changed to adjust the amount of different auxiliary materials added, thereby greatly reducing the workload of workers; During the mixing process, the servo motor 28 is started, and the output shaft of the servo motor 28 drives the first gear 27 to rotate, the first gear 27 drives the second gear 31 to rotate, the second gear 31 drives the rotating outer cylinder 11 to rotate, and the rotating outer cylinder 11 drives the external multiple first stirring blades 16 and second stirring blades 19 to rotate, so as to fully mix the materials. The setting of the first scraper 15 can prevent the materials from remaining on the inner wall of the mixing cylinder 1, and at the same time, the side of the second push piece 17 is in contact with the inner wall of the second fixed conical plate 9, which further improves the stirring efficiency and reduces the residue. When the auxiliary materials are fed into the device through the multiple feeding holes 32, the various auxiliary materials will first fall into the third fixed conical plate 13 instead of directly entering the mixing barrel 1. When the rotating outer barrel 11 rotates, the third fixed conical plate 13 will be driven to rotate. The third fixed conical plate 13 will preliminarily mix the various auxiliary materials, thereby reducing the subsequent mixing time. At the same time, through the continuous rotation of the third stirring blade 20, the auxiliary materials can only be slowly fed into the mixing barrel 1, thereby ensuring that the auxiliary materials are evenly distributed, reducing the subsequent mixing time, and improving work efficiency. After the mixing is completed, the multi-stage electric telescopic rod 24 is started, and the piston rod of the multi-stage electric telescopic rod 24 drives the side support horizontal plate 25 to rise, and the side support horizontal plate 25 drives the sliding inner rod 12 to rise, and the sliding inner rod 12 drives the blocking block 58 to rise, and the blocking block 58 no longer blocks the discharge pipe 18. At this time, the mixed material is discharged through the discharge pipe 18, and the sliding inner rod 12 drives the connecting rod 23 to rise, and the connecting rod 23 drives the vertical rod 26 to rise, and the vertical rod 26 drives the internal sliding conical plate 43 to rise. At this time, the sliding conical plate 43 pushes the auxiliary material upward, and because the sliding conical plate 43 is slidably sleeved on the outer wall of the fixed barrel 44, the auxiliary material can be continuously at the top of the sliding conical plate 43, avoiding falling into the gap between the sliding conical plate 43 and the first fixed conical plate 7, reducing the difficulty of subsequent cleaning; When the sliding conical plate 43 is lifted, the sliding conical plate 43 no longer presses the sliding block 29, and the clamping plate 33 moves laterally under the elastic force of the second spring 38. At this time, one end of the clamping plate 33 is inserted into the inside of the clamping groove 41 to brake the block 30 to prevent the block 30 from sliding. At this time, the mixed material below is being discharged. As the sliding conical plate 43 continues to rise, the sliding conical plate 43 pushes the auxiliary material into the inside of the fixed barrel 44 until the sliding conical plate 43 moves to the highest point of the fixed barrel 44. At this time, the auxiliary material has filled the space inside the annular inner plate 53. At the same time, the sliding conical plate 43 continuously pushes the convex strip 54 to move horizontally when it rises. The convex strip 54 drives the two second scrapers 47 to approach each other until the two second scrapers 47 fit together. After the interior of the annular inner plate 53 is filled and the material below is discharged, the multi-stage electric telescopic rod 24 is started again, and the piston rod of the multi-stage electric telescopic rod 24 is retracted and restored to the initial state. The two second scrapers 47 move away from each other under the tension of the tension spring 55, and the bottom of the second scraper 47 scrapes off the excess auxiliary material remaining on the surface of the annular inner plate 53 to ensure quantitative accuracy. When the sliding conical plate 43 moves to the lowest point again, the sliding conical plate 43 squeezes the sliding block 29 again, and the sliding block 29 enters the interior of the trapezoidal groove 39. The clamping plate 33 is retracted into the interior of the transverse groove 34 and squeezes the second spring 38 to release the braking state of the stopper 30. At this time, the auxiliary material inside the annular inner plate 53 pushes the stopper 30, and the stopper 30 starts to move downward, and the auxiliary material enters the interior of the third fixed conical plate 13. At this time, the blocking block 58 enters the interior of the discharge pipe 18 again to ensure the sealing of the device. After the auxiliary material is added, the stopper 30 is reset under the elastic force of the first spring 37, which is convenient for the next use; When adjusting the size of the annular inner plate 53, the rotating block 21 can be rotated first, and the rotating block 21 drives the threaded rod 45 to rotate, and the threaded rod 45 drives the pressure plate 48 to rotate. At this time, the rotating block 21, the threaded rod 45 and the pressure plate 48 all rise and no longer press the arc plate 50. At this time, the two arc plates 50 can be pulled upward, and the positioning rod 51 and the positioning groove 52 are no longer engaged. After the annular inner plate 53 is removed from the inside of the fixed barrel 44, the annular inner plates 53 of different sizes can be replaced, which reduces the difficulty of operation and improves the scope of application of the device.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
