[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] For examples, please refer to Figures 1-5 A spraying device for easy adjustment of the nozzle 12 includes a spraying box 1 and a storage tank 2. A pump body 3 is fixedly installed on the outer wall of the spraying box 1. A conveying pipe 4 connects the inlet end of the pump body 3 and the storage tank 2. Spraying equipment and support equipment are installed inside the spraying box 1. The support equipment includes a support plate 5, which is installed inside the spraying box 1 through a height adjustment device. The spraying equipment includes multiple mounting shells 6. A main spraying pipe 7 is fixedly connected to the bottom end of the mounting shell 6. A conveying pipe 8 connects the discharge end of the pump body 3 and the main spraying pipe 7. A sealing gasket 9 is slidably arranged inside the main spraying pipe 7. A secondary spraying pipe 10 is fixedly connected to the sealing gasket 9. A moving device is installed between the main spraying pipe 7 and the secondary spraying pipe 10. A connecting pipe 11 is fixedly connected to the bottom end of the main spraying pipe 7 and the secondary spraying pipe 10. A nozzle 12 is threadedly connected to the connecting pipe 11, and a sealing structure is provided inside the connecting pipe 11.
[0024] The support plate 5 supports the electronic components to be sprayed, and the height adjustment device allows for easy adjustment of the distance between the electronic components and the nozzle 12, which improves the spraying effect. The moving device allows for easy movement of the auxiliary spraying pipe 10, which in turn allows for easy adjustment of the position of the nozzle 12, thus better accommodating electronic components of different sizes. The sealing gasket 9 prevents paint leakage, and the sealing structure ensures that the connecting pipe 11 connected to the nozzle 12 that is not in use is sealed, further preventing paint waste. When the pump body 3 is working, the paint inside the storage tank 2 is transported through the first conveying pipe 4, the second conveying pipe 8, the main spraying pipe 7, and the auxiliary spraying pipe 10, and then sprayed through the nozzle 12 onto the surface of the electronic components on the support plate 5, thereby achieving the spraying effect.
[0025] Please see Figure 2 The height adjustment device includes a fixed block 13 and a movable block 14. The fixed block 13 is fixedly connected to the inner bottom wall of the spray box 1, and the movable block 14 is slidably installed on the outside of the fixed block 13. The support plate 5 is fixedly connected to the top of the movable block 14. The fixed block 13 has multiple limiting holes inside, and the movable block 14 is inserted into the limiting holes to form a limiting strip 15.
[0026] By moving the movable block 14, the height of the support plate 5 can be adjusted. Once the height of the support plate 5 is appropriate, the limiting strip 15 can be inserted into the movable block 14 and the fixing block 13 to fix the support plate 5. The height-adjustable support plate 5 can help improve the coating effect of electronic components.
[0027] Please see Figure 3 and Figure 4 The moving device includes a gear 16 and a rack 17. The rack 17 is slidably installed inside the mounting housing 6, and the gear 16 is rotatably installed inside the mounting housing 6. The gear 16 and the rack 17 mesh with each other. A rotating shaft 18 is fixedly connected to the top of the gear 16, and a handle 19 is fixedly connected to the top of the rotating shaft 18. A connecting block 20 is fixedly connected between the rack 17 and the auxiliary spray pipe 10.
[0028] Turning the handle 19 causes the shaft 18 to rotate the gear 16, which in turn moves the rack 17. With the connection of the connecting block 20, the auxiliary spray pipe 10 can be moved, thus facilitating the adjustment of the nozzle 12 position. This allows the device to better adapt to electronic components of different sizes, greatly improving its applicability.
[0029] Please see Figure 5The sealing structure includes a fixing frame 21 and a sealing ball 22. The fixing frame 21 is fixedly installed inside the connecting pipe 11, and the sealing ball 22 is rolled inside the connecting pipe 11. A spring 23 is installed between the fixing frame 21 and the sealing ball 22. Under the action of the spring 23, the sealing ball 22 will seal the connecting pipe 11.
[0030] When the corresponding nozzle 12 is needed, simply rotate the nozzle 12 so that it moves upward inside the connecting pipe 11, thereby opening the sealing ball 22. This allows the nozzle 12 and the auxiliary spray pipe 10 to communicate normally. When the specific nozzle 12 is not used, simply rotate the nozzle 12 so that it moves downward. Under the action of the spring 23, the sealing ball 22 can fit tightly against the inner wall of the connecting block 20, thereby achieving a sealing effect and preventing paint waste.
[0031] Please see Figure 4 A mounting block 24 is fixedly connected to the outer wall of the rack 17, and an elastic sealing tube 25 is installed between the mounting block 24 and the mounting shell 6.
[0032] The mounting block 24 and the elastic seal can provide a sealing and protection effect for the rack 17, thereby ensuring that the rack 17 can be used normally and will not be affected by the paint.
[0033] Please see Figure 3 and Figure 4 The top of the connecting block 20 is fixedly connected to a limiting rod 26, and the limiting rod 26 is slidably connected to the mounting shell 6.
[0034] The limiting rod 26 can limit the connecting block 20, making the movement of the secondary spray pipe 10 smoother.
[0035] In summary, the working principle and process of this spraying device with adjustable nozzle 12 are as follows: First, place the device at the desired location. Adjust the height of the support plate 5 according to the electronic components to be sprayed, ensuring a suitable distance between the electronic components and the nozzle 12. Then, insert the limiting strip 15 into the moving block 14 and the fixing block 13 to secure the support plate 5. Next, select the appropriate nozzle 12 based on the size of the electronic components and rotate the handle 19 to move the nozzle 12. Once the nozzle 12 is in the correct position, rotate it to push against the sealing ball 22 and move it upwards, ensuring normal operation of the nozzle 12. Finally, start the pump body 3 to spray the electronic components. This device is highly adaptable and prevents paint waste, making it highly practical.
[0036] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
