[0035] In order to facilitate the understanding of the present invention, the present application will be described more comprehensively with reference to the relevant drawings below; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0036] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are for illustrative purposes only and do not represent the only implementation method.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] like Figures 1 to 8 As shown, the present application provides a spray drying device for the production of electric vehicle parts, including a drying chamber 100, a conveying track 110 and a brake drum 120. The conveying track 110 passes through the drying chamber 100 and is fixed in the drying chamber 100. The conveying track 110 is used to convey the brake drum 120 and convey the brake drum 120 to the drying chamber 100. The device also includes a spraying assembly 200, which is used to spray the brake drum 120.

[0039] The spray assembly 200 includes a moving device 210, a spray station 1 220 and a spray station 230;

[0040] The moving device 210 moves in the conveying track 110 , and the brake drum 120 is a cylinder with a hollow interior, an open end, and a closed end, and is fixed to the bottom of the moving device 210 ;

[0041] The paint spraying seat 1 220 is a hollow cylinder located on one side of the opening of the brake drum 120. The paint spraying seat 1 220 is used to spray paint on the open end surface of the brake drum 120.

[0042] The second paint spraying seat 230 is a hollow cylinder with a hollow interior and an open end, and its open end is close to the closed end of the brake drum 120 . The second paint spraying seat 230 is used to spray paint on the closed end surface of the brake drum 120 .

[0043] Specifically, if Figures 3 to 8 As shown, the diameter of the first spray paint seat 220 is not greater than the diameter of the open end of the brake drum 120 , and the opening diameter of the second spray paint seat 230 is not less than the diameter of the closed end of the brake drum 120 .

[0044] It is easy to understand that the paint spraying range of the first paint spraying seat 220 can cover the concave surface of the brake drum 120, and the paint spraying range of the second paint spraying seat 230 can cover the concave surface of the brake drum 120, while not easily splashing too much.

[0045] Specifically, if Figures 3 to 6 As shown, the paint spraying seat 1 220 is filled with paint liquid, and a nozzle 1 221 is fixed at one end thereof close to the brake drum 120, and the nozzle 1 221 is communicated with the interior of the paint spraying seat 1 220;

[0046] The second paint spraying seat 230 is filled with paint liquid, and a spray head 231 is fixed on a side thereof close to the brake drum 120 , and the spray head 231 is communicated with the interior of the second paint spraying seat 230 .

[0047] It is easy to understand that the paint liquid in the paint spraying seat 1 220 is sprayed out from the nozzle 1 221 , and the paint liquid in the paint spraying seat 2 230 is sprayed out from the nozzle 231 .

[0048] Specifically, if Figures 5 to 7 As shown, the spray assembly 200 further includes an air supply pipe 240;

[0049] One end of the air supply pipe 240 is connected to the air pump, and the other end of the air supply pipe 240 is fixed with a branch pipe 241;

[0050] The branch pipe 241 has two air outlet ends. One air outlet end of the branch pipe 241 extends into the first paint spray seat 220 , and the other air outlet end of the branch pipe 241 extends into the second paint spray seat 230 .

[0051] This means that by increasing the pressure in the air supply pipe 240, the paint liquids in the paint spraying seat 1 220 and the paint spraying seat 2 230 are sprayed out simultaneously.

[0052] Specifically, if Figures 3 to 7 As shown, a ring plate 223 is fixed on the side of the paint spraying seat 1 220, and a plurality of nozzles 2 2231 are fixed evenly spaced on the inner ring surface of the ring plate 223;

[0053] The second nozzle 2231 is used for spraying the side of the brake drum 120 .

[0054] Specifically, if Figures 3 to 7 As shown, there is a gap between the annular plate 223 and the paint spraying seat 220 , and the brake drum 120 is located in the gap between the annular plate 223 and the paint spraying seat 220 .

[0055] It is worth noting that the brake drum 120 is located between the annular plate 223 and the paint spraying seat 220, which can better spray the outer side of the brake drum 120.

[0056] In the above embodiment, the moving device 210 drives the brake drum 120 to move on the conveying track 110. During the conveying process, the air supply pipe 240 is pressurized, so that the paint liquid in the paint spray seat 1 220 is sprayed from the nozzle 1 221 and the nozzle 2 2231 to spray the concave surface and the outer side of the brake drum 120 respectively. At the same time, the paint liquid in the paint spray seat 2 230 is sprayed to spray the convex surface of the brake drum 120. It is possible to spray the inside and outside of the brake drum 120 at the same time during the conveying process, and the time difference in transportation is used to complete the processing of the brake drum 120 in the next process, thereby improving the processing efficiency.

[0057] In some embodiments of the present application, Figures 3 to 8As shown, four positioning soft bags 222 are fixed to one end of the paint spraying seat 120 close to the brake drum 120, and an annular tube is fixed inside the paint spraying seat 120, and each positioning soft bag 222 is evenly connected to the inside of the annular tube;

[0058] An air guide tube 242 is fixed to the branch tube 241 near the paint spray seat 1 220. The free end of the air guide tube 242 extends into the annular tube. The air guide tube 242 is used to inflate the positioning soft bag 222.

[0059] The brake drum 120 is provided with four reserved holes 121 , which facilitate installation of the brake drum 120 and assembly of the brake drum 120 with other components. A positioning soft bag 222 is expanded and extends into a reserved hole 121 .

[0060] Specifically, if Figures 5 to 8 As shown, a valve is fixed on the air guide tube 242, and the valve is used to control the air intake into the positioning soft bag 222. There are valves on both air outlet ends of the branch tube 241. When the valve of the branch tube 241 is closed, it does not affect the air intake into the air guide tube 242.

[0061] In the above embodiment, the brake drum 120 is placed between the paint spray seat 1 220 and the paint spray seat 2 230. At this time, the valves on the branch pipe 241 are all in the closed state, the valve of the air duct 242 is opened, and the air is pumped into the air supply pipe 240 and the air is supplied to the air duct 242, so that the positioning soft bag 222 expands and extends into the reserved hole 121 of the brake drum 120, thereby clamping and fixing the brake drum 120. At the same time, the reserved hole 121 that does not need to be sprayed can be blocked, so that the brake drum 120 is located in the space between the paint spray seat 1 220 and the paint spray seat 2 230, reducing the flying paint mist and improving the environmental friendliness of use.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. A person skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
