[0023] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, the aluminum profile powder coating and recycling device of this utility model includes a powder coating chamber 1, in which a first return pipe 13 is provided; a feeding chamber 2, in which a first extraction device 23 and a powder feeding center 25 are provided. The first extraction device 23 is provided with an inlet 231 and a first outlet 232. The inlet 231 is connected to the outlet end of the first return pipe 13, and the first outlet 232 is connected to the inlet end of the powder feeding center 25. The powder feeding center 25 is provided with a first recycling port 251 and a second recycling port 252. The first recycling port 251 is connected to a first recycling pipe 26, and the second recycling port 252 is connected to a second recycling pipe 27; and a recycling chamber 3, in which a second extraction device 33 and a recycling center 34 are provided. The inlet end of the second extraction device 33 is connected to the outlet ends of the first recycling pipe 26 and the second recycling pipe 27, respectively, and the outlet end of the second extraction device 33 is connected to the recycling center 34. With this setup, when the residual material in the powder spraying chamber 1 needs to be recycled, the residual material enters the first extraction device 23 after passing through the first return pipe 13, then enters the powder supply center 25, and is then recycled to the recycling chamber 3 through the first recycling pipe 26 and the second recycling pipe 27. After passing through the second extraction device 33, it is collected uniformly in the recycling center 34, forming a powder recycling pipeline, which facilitates subsequent processing. Among them, the powder supply center 25 is equipped with dual recycling ports and dual recycling pipes, which makes the recycling effect better and the recycling efficiency higher.

[0025] In practical applications, when spraying the same powder, the powder that returns to the powder supply center 25 can be fed back into the spray gun in the powder spraying chamber 1 through the supply pipe to perform cyclic spraying on the aluminum profile workpiece. This is existing technology, so it will not be described in detail. When it is necessary to change to another powder, the previous coating needs to be recycled to avoid color mixing.

[0026] Furthermore, the first recovery port 251 is located at the lower part of the powder supply center 25, and the second recovery port 252 is located at the upper part of the powder supply center 25. This arrangement ensures that, due to the pressure exerted when the second extraction device 33 feeds the remaining material into the recovery center 34, the powder at the bottom of the powder supply center 25 will be blown up and rebound. Therefore, by placing the first recovery port 251 at the lower part and the second recovery port 252 at the upper part of the powder supply center 25, effective recovery can be achieved from both the upper and lower parts of the powder supply center 25, resulting in better recovery performance.

[0027] Furthermore, there are two second recovery ports 252; the second recovery pipe 27 includes a main pipe 271, a first auxiliary pipe 272, and a second auxiliary pipe 273. The inlet ends of the first auxiliary pipe 272 and the second auxiliary pipe 273 are respectively connected to the two second recovery ports 252, and the outlet ends of the first auxiliary pipe 272 and the second auxiliary pipe 273 are both connected to the inlet end of the main pipe 271. The outlet end of the main pipe 271 is connected to the second extraction device 33, and a butterfly valve 276 is provided between the inlet end and the outlet end of the main pipe 271. This arrangement, with two second recovery ports 252, can improve the recovery effect and prevent powder from being blown up, rebounding, and overflowing.

[0028] In practical applications, the two second recovery ports 252 are set in parallel and at intervals, which can synchronously suck up the powder on the same plane above the powder supply center 25, thereby blocking the powder from being blown up and rebounding.

[0029] Furthermore, the discharge end of the second auxiliary pipe 273 is connected to the inlet end of the main pipe 271 via a tee pipe 274, and the discharge end of the first auxiliary pipe 272 is connected to the inlet end of the main pipe 271 via an elbow 275 connected to the tee pipe 274. This arrangement facilitates assembly via the tee pipe 274 and the elbow 275, and allows the discharge ends of the second auxiliary pipe 273 and the first auxiliary pipe 272 to converge via the tee pipe 274 before entering the main pipe 271.

[0030] In practical applications, the diameter of the main pipe 271 is larger than the diameters of the second auxiliary pipe 273 and the first auxiliary pipe 272.

[0031] Furthermore, the first extraction device 23 is also equipped with a second discharge port 233, and the second extraction device 33 is equipped with a second return pipe 31. The inlet end of the second return pipe 31 is connected to the second discharge port 233 and the first recovery pipe 26, respectively. With this configuration, in special circumstances, such as when the supply room 2 needs maintenance and cleaning, or when the remaining material cannot be recycled again, in order to recover without stopping the machine, the second discharge port 233 can be opened and the first discharge port 232 closed. This allows the powder from the powder spraying chamber 1 to enter the first extraction device 23 through the first return pipe 13 and then enter the second return pipe 31 to be recovered and collected in the second extraction device 33 for processing. The powder does not need to return to the powder supply center 25. In this way, the powder from the powder supply center 25 can be recovered after the remaining material in the powder spraying chamber 1 has been processed, avoiding material mixing.

[0032] In practical applications, the first material extraction device 23 and the second material extraction device 33 are centrifugal fans.

[0033] Furthermore, the recycling chamber 3 is equipped with a filter device 32, which is located between the second material extraction device 33 and the recycling center 34. This arrangement allows the powder to be filtered by the filter device 32 before being collected in the recycling center 34.

[0034] Furthermore, the feeding chamber 2 is equipped with a conical recycling cylinder 21 and a fixing frame 22. The conical recycling cylinder 21 is fixed inside the feeding chamber 2 by the fixing frame 22. The inlet end of the conical recycling cylinder 21 is connected to the first outlet 232, and the outlet end of the conical recycling cylinder 21 is connected to the powder feeding center 25. This configuration improves the material guiding effect by guiding the powder through the conical recycling cylinder 21 to the powder feeding center 25.

[0035] Furthermore, a pedestrian ladder 24 is fixed to the side of the material supply room 2. This arrangement facilitates the maintenance and cleaning of the material supply room 2.

[0036] Furthermore, the powder coating booth 1 is equipped with a V-shaped curtain 11 and an exhaust box 12. The exhaust box 12 is located at the bottom of the V-shaped curtain 11 and is connected to the inlet end of the return pipe 13. With this configuration, when the aluminum profile workpiece is placed between the V-shaped curtains 11 during powder coating, the excess powder will be guided through the V-shaped curtains 11 to the exhaust box 12 for collection and recycling, resulting in better performance.

[0037] Furthermore, the powder spraying chamber 1, the material supply chamber 2, and the recycling chamber 3 are arranged side by side and spaced apart, with the material supply chamber 2 located between the powder spraying chamber 1 and the recycling chamber 3. This arrangement, with the powder spraying chamber 1, the material supply chamber 2, and the recycling chamber 3 arranged side by side and spaced apart, and the material supply chamber 2 located between the powder spraying chamber 1 and the recycling chamber 3, makes it more convenient to install pipelines and makes reasonable use of the space occupied by the whole machine.

However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present utility model.
