[0023] As Figure 1 shown, a spraying device for urban rail vehicles includes a support platform 1, a spraying box 2 is arranged above the support platform 1, a driving device 4 is arranged above the spraying box 2, an air inlet pipe 6 is arranged at one end above the spraying box 2, and a first filter screen 7 is arranged above the air inlet pipe 6. A spraying device 5 is arranged on one side of the spraying box 2, and a recycling device 8 is arranged below the support platform 1. The driving device 4 is used to drive the components to rotate;

[0024] Among them, the recycling device 8 includes a fan 806, a plastic powder micro-mesh 804 and a storage tank 801. The fan 806 filters the plastic powder through the plastic powder micro-mesh 804 and retains it in the storage tank 801.

[0025] In this embodiment, when preparing to spray plastic on the parts, first pour the plastic powder into the storage tank 801 through the plastic powder inlet 807, open the first movable door 3 and fix the parts through the sling 404, and close the first movable door 3. At this time, start the spraying device 5, the driving device 4, and the recycling device 8 simultaneously. When the spraying device 5 is started, the electrostatic powder feeding device 501 starts to work, so that the plastic powder enters the plastic inlet pipe 504 from the storage tank 801, and enters the electrostatic powder feeding device 501 through the plastic inlet pipe 504. Through the treatment of the electrostatic powder feeding device 501, the plastic powder enters the plastic outlet pipe 502 through the electrostatic powder feeding device 501, and the plastic powder is sprayed out through the plastic powder nozzle 503 on the plastic outlet pipe 502, so as to spray plastic on the parts. When the driving device 4 is started, the motor 401 starts to work. Since the motor 401 works, the output shaft 402 starts to rotate, and the fixed disk 403 below the output shaft 402 rotates together. Due to the rotation of the fixed disk 403, the sling 404 rotates, and the parts start to rotate, so as to spray plastic on the parts comprehensively. When the recycling device 8 is started, the fan 806 starts to work, so that the external air enters the spraying box 2 through the first filter screen 7. At this time, the excess plastic powder sprayed from the spraying device 5 will flow together with the entering air. At this time, the plastic powder enters the inside of the storage tank 801 through the second filter screen 803, so that the plastic powder is filtered by the plastic powder micro-mesh 804 at the upper end of the storage tank 801 and retained inside the storage tank 801, while the air enters the air outlet pipe 805 through the plastic powder micro-mesh 804 and enters the fan 806 through the air outlet pipe 805 and is discharged. Through the combination of the processes of the spraying device 5, the driving device 4, and the recycling device 8, the parts can be sprayed with plastic comprehensively, and the excess plastic powder can be recycled, thus completing a series of work.

[0026] As Figure 2 shown, the driving device 4 includes a motor 401, the motor 401 is fixedly connected to the spraying box 2, the motor 401 is fixedly connected with an output shaft 402, a fixed disk 403 is fixedly connected below the output shaft 402, and a sling 404 is fixedly connected below the fixed disk 403.

[0027] In the above method, when preparing to spray plastic on the parts, when the driving device 4 is started, the motor 401 starts to work. Since the motor 401 works, the output shaft 402 starts to rotate, and the fixed disk 403 below the output shaft 402 rotates together. Due to the rotation of the fixed disk 403, the sling 404 rotates, and the parts start to rotate, so as to spray plastic on the parts comprehensively.

[0028] As Figure 2 and Figure 3As shown, the powder spraying device 5 includes an electrostatic powder supply device 501. Above the electrostatic powder supply device 501, there is a fixed connection with a plastic powder outlet pipe 502. The upper end of the plastic powder outlet pipe 502 is fixedly connected to the powder spraying box 2. The other end of the plastic powder outlet pipe 502 is fixedly connected with multiple plastic powder nozzles 503. On one side of the electrostatic powder supply device 501, there is a fixed connection with a plastic powder inlet pipe 504. The other end of the plastic powder inlet pipe 504 is fixedly connected to a storage tank 801.

[0029] In the above manner, when preparing to spray a component, when the powder spraying device 5 is started, the electrostatic powder supply device 501 starts to work, causing the plastic powder to enter the plastic powder inlet pipe 504 from the storage tank 801, and then enter the electrostatic powder supply device 501 through the plastic powder inlet pipe 504. Through the treatment of the electrostatic powder supply device 501, the plastic powder enters the plastic powder outlet pipe 502 through the electrostatic powder supply device 501, and the plastic powder is ejected through the plastic powder nozzles 503 on the plastic powder outlet pipe 502, thereby spraying the component.

[0030] As Figure 3 shown, the recovery device 8 includes a storage tank 801 and a second filter screen 803. The second filter screen 803 is fixedly connected to the support platform 1, and the storage tank 801 is fixedly connected to the support platform 1. On one side of the storage tank 801, there is a fixed connection with an air outlet pipe 805.

The other end of the air outlet pipe 805 is fixedly connected to a blower 806. On the upper end of the other side of the storage tank 801, there is a fixed connection with a plastic powder inlet 807.

[0031] In the above manner, when preparing to spray a component, when the recovery device 8 is started, the blower 806 starts to work, causing the external air to enter the powder spraying box 2 through the first filter screen 7. At this time, the excess plastic powder ejected from the powder spraying device 5 will flow along with the incoming air. At this time, the plastic powder enters the interior of the storage tank 801 through the second filter screen 803, so that the plastic powder is retained inside the storage tank 801 after passing through the filtration of the plastic powder micro-mesh 804 at the upper end of the storage tank 801, while the air enters the air outlet pipe 805 through the plastic powder micro-mesh 804 and is discharged into the blower 806 through the air outlet pipe 805, thereby recycling and reusing the residual plastic powder.

[0032] As Figure 1 and Figure 2 shown, on one side of the powder spraying box 2, there is a through hole. Inside the through hole opened in the powder spraying box 2, there is a first movable door 3, and the first movable door 3 is rotatably connected to the powder spraying box 2 through a damping hinge 9. Above the powder spraying box 2, there is a through hole. The through hole opened in the powder spraying box 2 is matched with an air inlet pipe 6, and the lower end of the air inlet pipe 6 is fixedly connected to the through hole opened above the powder spraying box 2. The upper end of the air inlet pipe 6 is fixedly connected to the first filter screen 7.

[0033] In the above - mentioned method, the first movable door 3 installed is made of a transparent material, which can well observe the powder spraying condition in the powder spraying box 2. And the air inlet pipe 6 and the first filter screen 7 installed above the powder spraying box 2 are for generating air flow when the recycling device 8 is started, so as to better recycle and reuse the residual plastic powder. The installed first filter screen 7 can filter and remove dust and impurities in the air to prevent affecting the powder spraying effect.

[0034] As Figure 2 and Figure 3 shown, a through - hole is opened in the middle position of the support platform 1, and the second filter screen 803 is arranged in the through - hole opened in the middle of the support platform 1, and the second filter screen 803 is fixedly connected to the support platform 1 through a locking member.

[0035] In the above - mentioned method, the locking member can be components such as bolts and buckles, and any other structure that can achieve a detachable fixing structure is acceptable. The installed detachable locking member enables the second filter screen 803 to be quickly disassembled, so that the impurities on the second filter screen 803 can be cleaned.

[0036] As Figure 1 and Figure 2 shown, a through - hole is opened on one side of the storage bin 801, a second movable door 802 is arranged in the through - hole opened in the storage bin 801, and the second movable door 802 is rotatably connected to the storage bin 801 through a damping hinge 9. A through - hole is opened at the upper end of the other side of the storage bin 801, a plastic powder micro - screen 804 is arranged in the through - hole opened at the upper end of the storage bin 801, and the outside of the through - hole opened at the upper end of the storage bin 801 is fixedly connected to an air outlet pipe 805.

[0037] In the above - mentioned method, the second movable door 802 installed at the upper end of the storage bin 801 is also made of a transparent material, which can observe the recycled plastic powder and also observe the remaining amount of plastic powder in the storage bin 801, so as to add plastic powder to it. Installing the plastic powder micro - screen 804, the air outlet pipe 805 and the fan 806 at the upper end of the storage bin 801 is for making the plastic powder accumulate on the plastic powder micro - screen 804 during the process of recycling plastic powder. Due to the action of gravity, the plastic powder falls off the plastic powder micro - screen 804 to the lower end inside the storage bin 801 and is then reused.

[0038] The working principle of this utility model is as follows: When preparing to spray plastic on parts, first pour the plastic powder into the storage tank 801 through the plastic powder inlet 807. Open the first movable door 3 and fix the parts through the sling 404, then close the first movable door 3. At this time, start the spraying device 5, the driving device 4, and the recycling device 8 simultaneously. When the spraying device 5 is started, the electrostatic powder feeding device 501 starts to work, causing the plastic powder to enter the plastic inlet pipe 504 from the storage tank 801, and then enter the electrostatic powder feeding device 501 through the plastic inlet pipe 504. Through the treatment of the electrostatic powder feeding device 501, the plastic powder enters the plastic outlet pipe 502 through the electrostatic powder feeding device 501, and the plastic powder is sprayed out through the plastic powder nozzle 503 on the plastic outlet pipe 502, thereby spraying plastic on the parts. When the driving device 4 is started, the motor 401 starts to work. Due to the operation of the motor 401, the output shaft 402 starts to rotate, causing the fixed disk 403 below the output shaft 402 to rotate together. Due to the rotation of the fixed disk 403, the sling 404 rotates, causing the parts to start rotating, thereby spraying plastic on the parts comprehensively. When the recycling device 8 is started, the fan 806 starts to work, causing the external air to enter the spraying box 2 through the first filter screen 7. At this time, the excess plastic powder sprayed from the spraying device 5 will flow together with the incoming air. At this time, the plastic powder enters the interior of the storage tank 801 through the second filter screen 803, so that the plastic powder is retained inside the storage tank 801 after being filtered by the plastic powder micro-mesh 804 at the upper end of the storage tank 801, while the air enters the air outlet pipe 805 through the plastic powder micro-mesh 804 and is discharged into the fan 806 through the air outlet pipe 805. Through the combination of the processes of the spraying device 5, the driving device 4, and the recycling device 8, the parts can be sprayed with plastic comprehensively and the excess plastic powder can be recycled, thus completing a series of operations.

[0039] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model.
