Description

Technical Field

[0001] This utility model relates to the technical field of plastic powder processing equipment, specifically a self-cleaning plastic powder mixer. Background Technology

[0002] Powder coating is a material used in powder coating processes. Simply put, it is plastic powder that has been heated to a high temperature and then sprayed onto the surface of a material using compressed air. Unused material can be repeatedly recycled and reused, although the effect will be slightly less. Powder coating is a thermosetting powder coating used for electrostatic spraying, and a mixer is often used for stirring during its processing.

[0003] The authorized publication number "CN221869630U" describes "a self-cleaning plastic powder mixer, including a shell, a horizontal plate, a first motor, a top plate, and a support plate. The horizontal plate is fixedly connected between the lower inner walls of the shell. The first motor is fixedly connected to the middle of the bottom left side of the horizontal plate, and the output end of the first motor passes through the middle of the bottom left side of the horizontal plate and extends to the upper side of the horizontal plate. The top plate is fixedly connected to the top left side of the inner cavity of the shell. The support plate is fixedly connected to the lower right side of the inner cavity of the shell. A first through hole is opened on the top right side of the shell. A water tank is fixedly connected to the top left side of the shell. This self-cleaning plastic powder mixer facilitates automatic cleaning, eliminating the need for manual cleaning of the mixer's interior with tools. It saves time and effort, is easy to use, has high mixing efficiency, and improves the overall efficiency of the plastic powder mixer."

[0024] Please see Figure 1-4 This utility model provides a technical solution: a self-cleaning plastic powder mixer, comprising:

[0025] Mixing cylinder 1;

[0026] A wall-scraping mechanism, located inside the mixing drum 1, is used to scrape and clean the inner wall of the mixing drum 1. The wall-scraping mechanism includes multiple sets of lifting components and a cleaning ring 2. The cleaning ring 2 is slidably connected inside the mixing drum 1. The multiple sets of lifting components are equidistantly arranged on the mixing drum 1, and each set of lifting components is connected to the cleaning ring 2.

[0027] A rinsing mechanism is located inside the mixing cylinder 1 and is used to rinse the inner wall of the mixing cylinder 1. The rinsing mechanism includes an input component, an angle adjustment component, and multiple nozzles 7. The multiple nozzles 7 are rotatably connected to the top of the mixing cylinder 1. The input component is located at the top of the mixing cylinder 1 and is connected to the multiple nozzles 7. The angle adjustment component is located inside the mixing cylinder 1 and is connected to the nozzles 7.

[0028] In this implementation scheme: the cleaning ring 2 is triangular in shape, which facilitates scraping and cleaning of the inner wall of the mixing cylinder 1. Multiple nozzles 7 are evenly distributed to achieve a thorough rinsing of the inner wall of the mixing cylinder 1, ensuring the effectiveness of use. The mixing cylinder 1 has an inlet at the top and an outlet at the bottom, which is existing technology and will not be described in detail here.

[0029] Specifically, each lifting component includes a telescopic cylinder 6 and a connecting rod 3. The telescopic cylinder 6 is fixedly connected to one side of the outer surface of the mixing cylinder 1, and the connecting rod 3 is movably inserted into the mixing cylinder 1. The bottom of the connecting rod 3 is fixedly connected to the cleaning ring 2, and the top of the connecting rod 3 is fixedly connected to the output end of the telescopic cylinder 6.

[0030] In this embodiment, the model of the telescopic cylinder 6 can be selected from those available on the market as needed, which will not be elaborated here. The telescopic cylinder 6 controls the connecting rod 3 to rise and fall, thereby completing the cleaning of the inner wall of the cleaning ring 2.

[0031] Specifically, the input components include a water pump 12 and a connecting ring 9. The water pump 12 is fixedly connected to the top of the mixing cylinder 1, and the connecting ring 9 is fixedly connected to the top of the mixing cylinder 1. One end of the connecting ring 9 is connected to the output end of the water pump 12. Multiple telescopic tubes 13 are equidistantly connected to the bottom of the connecting ring 9, and one end of each telescopic tube 13 is connected to each nozzle 7.

[0032] In this embodiment, the model of the water pump 12 can be selected from those available on the market as needed, which will not be elaborated here. The cleaning fluid is poured into the connecting ring 9 by the water pump 12 and guided by the telescopic pipe 13. The telescopic pipe 13 does not affect the use of the nozzle 7 during rotation.

[0033] Specifically, the angle adjustment component consists of multiple angle adjustment telescopic rods 8, one end of each angle adjustment telescopic rod 8 is rotatably connected to the top of the mixing cylinder 1, and the other end of each angle adjustment telescopic rod 8 is rotatably connected to each nozzle 7.

[0034] In this embodiment: the models of the multiple angle-adjusting telescopic rods 8 can be selected from those already available on the market as needed, which will not be elaborated on here. By extending and retracting the multiple angle-adjusting telescopic rods 8, the angle of the corresponding nozzle 7 can be controlled to ensure the effect of use.

[0039] In use, the plastic powder is put into the mixing cylinder 1 through the inlet at the top of the mixing cylinder 1. The stirring motor 10 controls the rotating shaft 5 to drive the stirring blade 4 to rotate, thus completing the mixing. After mixing, the powder is discharged through the outlet at the bottom of the mixing cylinder 1. When cleaning the mixing cylinder 1, the water pump 12 pumps the cleaning liquid in the water tank 11 into the corresponding nozzle 7 through the connecting ring 9 and multiple telescopic pipes 13 for spraying and rinsing. At the same time, the angle-adjusting telescopic rod 8 extends and retracts to control the angle of the nozzle 7. During the rinsing process, the telescopic cylinder 6 controls the extension and retraction of the connecting rod 3 to realize the raising and lowering of the cleaning ring 2, thus completing the scraping and cleaning of the inner wall of the mixing cylinder 1 and ensuring the effect of use.
