[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a powder spraying machine with a dustproof structure, including a base 1, a tank body 7 is fixedly connected to the top of the base 1, a fixing plate 8 is fixedly connected to the top of the tank body 7, a support column 11 is fixedly connected to the inside of the fixing plate 8, a driving gear 12 is fixedly connected to the outside of the support column 11, a motor 13 is arranged inside the fixing plate 8, a driven gear 14 is fixedly connected to the output end of the motor 13, a fixing column 15 is fixedly connected to the bottom of the driven gear 14, one end of the fixing column 15 is fixedly connected to a connecting column 26, one end of the connecting column 26 is fixedly connected to a rotating rod 28, a turntable 17 is fixedly connected to the bottom of the rotating rod 28, a stirring column 18 is fixedly connected to the bottom of the turntable 17, a plurality of stirring rods 19 are fixedly connected to the outside of the stirring column 18, an annular rack 10 is fixedly connected to the inner side of the fixing plate 8, a discharge plate 21 is arranged at the bottom of the tank body 7, a collecting box 9 is arranged at the bottom of the discharge plate 21, and a filter assembly is installed on the top of the base 1.

[0031] Specifically, the base 1 serves as the supporting foundation of the entire powder spraying machine, ensuring that the equipment is stably placed on the ground. Through the installation of the fixing plate 8, the motor 13, the driving gear 12 and other components can run stably on the top of the tank body 7. Through the connection of the support column 11, it is used to support the driving gear 12, thereby ensuring the stable rotation of the driven gear 14. The motor 13 provides rotational power, thereby driving the driven gear 14 to rotate, thereby transmitting the rotational power to the fixing column 15. At the same time, under the connection of the connecting column 26, the rotating rod 28 rotates, thereby transmitting the power to the turntable 17, and driving the rotating rod 28 to rotate, thereby driving the stirring rod 19 and the brush 20 to rotate, so that the brush 20 directly contacts the inner wall of the tank body 7, and removes the residual powder on the inner wall through the rotation action. Through the meshing connection of the annular rack 10, it provides additional control functions for the driven gear 14. Under the control of the controller 4, the baffle 22 is opened, so that the residue in the tank body 7 enters the collection box 9, thereby keeping the working environment clean.

[0032] Reference Figure 1 and Figure 3 The filtering component includes a negative pressure suction machine 3, the bottom of which is fixedly connected to the top of the base 1, the extraction end of the negative pressure suction machine 3 is connected to a delivery pipe 16, one end of the delivery pipe 16 is connected to a purification box 5, a cavity 25 is opened inside the purification box 5, an activated carbon filter 23 is fixedly connected inside the cavity 25, a filter element 24 is fixedly provided on the upper side of the activated carbon filter 23, and a connecting pipe 6 is fixedly connected to the top of the purification box 5.

[0033] Specifically, the start and stop of the negative pressure suction machine 3 are controlled. The extraction end of the negative pressure suction machine 3 is connected with a conveying pipe 16 for transmitting the generated negative pressure to the purification box 5. The conveying pipe 16 is connected to the tank body 7 through the connecting pipe 6, so that the dust inside the tank body 7 can be extracted into the purification box 5 under the action of negative pressure. After the dust enters the purification box 5, it is firstly filtered by the filter element 24. Large particles of dust are blocked here, and tiny dust is filtered. The adsorption characteristics of activated carbon are used to improve the filtering effect.

[0034] Reference Figure 2 The corresponding side of the outside of the driven gear 14 is meshed with the outside of the driving gear 12 and the annular rack 10, the outside of the fixed column 15 is rotatably connected to the top of the tank body 7, the top of the tank body 7 is fixedly connected with a rotating shaft 27, one end of the rotating rod 28 is rotatably connected to the bottom of the rotating shaft 27, a plurality of brushes 20 are arranged on the outside of the stirring rod 19, the outside of the brush 20 is in contact with the inside of the tank body 7, the bottom of the base 1 is fixedly connected with the annular rack 10, and a baffle 22 is arranged inside the discharge plate 21.

[0035] Specifically, through the design of the annular rack 10, the driven gear 14 rotates along the outside of the annular rack 10, so that the driven gear 14 moves horizontally on the top of the tank body 7, thereby enhancing the stirring and cleaning effects. When the driven gear 14 rotates and moves along the annular rack 10, the fixed column 15 will also rotate and move accordingly. When the fixed column 15 drives the rotating rod 28 to rotate through the connecting column 26, the rotating rod 28 can rotate around the rotating shaft 27, and then the brush 20 will rotate along the inner wall of the tank body 7, thereby cleaning the residue on the inner wall. When the tank body 7 needs to be cleaned, the baffle 22 is opened by starting the controller 4, so that the residue enters the collection box 9 through the discharge plate 21.

[0036] Reference Figure 3 A support plate 2 is fixedly connected to the top of the base 1, a controller 4 is fixedly connected to the top of the support plate 2, the controller 4 is electrically connected to the negative pressure suction machine 3 and the discharge plate 21 respectively, one end of the connecting pipe 6 is fixedly connected to one side of the tank body 7, and the outside of the filter element 24 is fixedly connected to the inside of the purification box 5.

[0037] Specifically, the controller 4 serves as the core of the entire system. It is responsible for controlling the operation of the negative pressure suction machine 3 and the discharge plate 21. When it is necessary to clean the dust in the tank body 7, the controller 4 will send a start signal to the negative pressure suction machine 3 to start working, thereby ensuring that the dust in the tank body 7 can smoothly pass through the connecting pipe 6 into the purification box 5 for filtration and purification under the action of negative pressure. It can ensure that during the negative pressure suction process, the dust is first intercepted and filtered by the filter element 24 after entering the purification box 5, and large particles of dust are blocked on the outside of the filter element 24, while tiny dust continues to enter the activated carbon filter 23 for further filtration and purification.

[0038] Working principle: by starting the motor 13, it drives the driven gear 14 to rotate along the outside of the meshing driving gear 12, and then driven by the driven gear 14, the fixed column 15 rotates on the top of the tank body 7, and then under the connection of the connecting column 26, one end of the fixed column 15 drives the rotating rod 28 to rotate, so that the rotating rod 28 drives the turntable 17 to rotate, and under the drive of the turntable 17, the stirring column 18 drives the stirring rod 19 to rotate along the inner wall of the tank body 7, so that the brush 20 outside the stirring rod 19 cleans the inner wall of the tank body 7. At the same time, under the control of the controller 4, the baffle 22 inside the discharge plate 21 is opened, so that the residue enters the inside of the collection box 9, and then effectively cleans and avoids the residue from overflowing;

[0039] Secondly, when the controller 4 is started, the negative pressure suction machine 3 generates suction inside the purification box 5 through the delivery pipe 16, so that the dust inside the tank body 7 enters the purification box 5 through the extraction of the connecting pipe 6, and then the large particles of dust are blocked under the preliminary filtration of the filter element 24, and then the tiny dust is filtered again under the filtration of the activated carbon filter 23, and then the purified airflow is discharged to the outside through the support column 11, so as not to pollute the environment.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
