[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0026] Please see Figure 1-4 In this utility model: a quick-detachable spraying device includes a housing 1, a conveyor belt 2 installed on the inner bottom wall of the housing 1, a material box 3 set on the top of the housing 1, a threaded hole 4 opened at the bottom of the material box 3, a through hole 5 opened on the inner top wall of the threaded hole 4, a mounting block 6 threadedly connected to the inner wall of the threaded hole 4, a discharge pipe 7 fixedly connected to the mounting block 6, a sealing ring 8 sleeved on the discharge pipe 7, a spray nozzle 9 installed at the bottom end of the discharge pipe 7, a round hole 101 opened on the top of the housing 1, and the back of the material box 3... A feeding pipe 10 is connected to the box 1, and a valve is installed on the feeding pipe 10. A fixing plate 11 is fixedly connected to the back of the box 1. A support column 12 is fixedly connected to the top of the fixing plate 11. A support plate 13 is rotatably connected to the top of the support column 12. An electric push rod 14 is inserted through the support plate 13 and fixedly connected to it. A lifting plate 15 is fixedly connected to the telescopic end of the electric push rod 14. A square rod 16 is fixedly connected to the bottom of the lifting plate 15. A square hole 17 is opened on the top of the material box 3. A piston plate 18 is slidably connected to the inner wall of the material box 3.

[0027] In this invention, the conveyor belt 2 can transport the workpiece to be sprayed to the area below the nozzle 9 for spraying. During spraying, the electric push rod 14 is turned on to drive the lifting plate 15 to descend. The lifting plate 15 will drive the square rod 16 through the square hole 17 to squeeze the piston plate 18. After being squeezed, the piston plate 18 will move downward along the inner wall of the material box 3. During the process, the piston plate 18 will squeeze the paint in the material box 3 into the discharge pipe 7. The discharge pipe 7 is fixed by the mounting block 6. The sealing ring 8 is used to seal between the mounting block 6 and the threaded hole 4. After the paint enters the discharge pipe 7, the paint will be atomized and sprayed out from the nozzle 9, thereby realizing the spraying of the workpiece.

[0028] Multiple mounting blocks 6 for the spraying device can be prepared. Different types of nozzles 9 are installed at the bottom of the discharge pipe 7 on each mounting block 6. The material box 3, the discharge pipe 7 at its bottom, and the nozzles 9 constitute a spraying unit. This spraying unit is not fixedly connected to the housing 1. Therefore, when the nozzle 9 needs to be replaced, the square rod 16 is raised, and the material box 3 can be directly removed from the housing 1. Then, the discharge pipe 7 can be removed by rotating the mounting block 6. Next, the mounting block 6 of the required type of nozzle 9 is located, and the mounting block 6 is rotated onto the threaded hole 4 to complete the replacement of the nozzle 9. The process is very convenient and quick.

[0029] When the paint needs to be replaced, the existing spraying device requires cleaning of the material tank 3, the discharge pipe 7, and the nozzle 9. Multiple material tanks 3 can be prepared in advance, and each material tank 3 can hold different paints. When the paint needs to be replaced, the original material tank 3 can be replaced with the material tank 3 containing the required paint, and the paint replacement can be completed without cleaning the nozzle 9, the discharge pipe 7, or the material tank 3, which effectively improves the efficiency of paint replacement.

[0030] Please see Figure 3 The top of the box 1 is fixedly connected to two positioning plates 19, and the left and right sides of the material box 3 are fixedly connected to positioning frames 20. The inner sides of the two positioning frames 20 are slidably connected to the two positioning plates 19 respectively.

[0031] In this invention, the positioning plate 19 and the positioning frame 20 can position the material box 3, thereby ensuring that the square rod 16 is accurately inserted into the square hole 17 to drive the piston plate 18, thus improving the practicality of the device.

[0032] Please see Figure 3 Among them, the top of the piston plate 18 is fixedly connected to a limiting rod 21, which is square in shape, and the bottom of the square rod 16 is provided with a limiting hole 22.

[0033] In this invention, the limiting rod 21 and the limiting hole 22 can limit the descent of the piston plate 18, allowing the piston plate 18 to descend horizontally, thereby improving the stability of the piston plate 18's descent and the stability of the paint delivery.

[0034] Please see Figure 3 Among them: the bottom of the lifting plate 15 is fixedly connected to two insert plates 23, and electromagnets 24 are fixedly connected to the opposite sides of the two insert plates 23. Both positioning frames 20 are metal layers.

[0035] In this invention, when replacing the nozzle 9, the user first controls the electric push rod 14 to lower the lifting plate 15, and the insert plate 23 will be inserted into the positioning frame 20. At this time, the electromagnet 24 is turned on, and the electromagnet 24 will magnetically attract the positioning frame 20. Then, the electric push rod 14 is turned on in the opposite direction, and the electric push rod 14 will raise the material box 3 through the lifting plate 15 and the insert plate 23. Then, the fixing plate 11 is rotated, and the fixing plate 11 will rotate on the support column 12. The material box 3 will move to one side of the box 1, which makes it convenient for the user to replace the nozzle 9. By turning off the electromagnet 24, the magnetic attraction to the positioning frame 20 can be lost, and the material box 3 can be released to help the worker replace the material box 3 and complete the replacement of the paint.

[0036] Please see Figure 3 The material bin 3 has a distance sensor 25 installed on its inner top wall, and a buzzer 26 is installed on the front of the box 1. The output of the distance sensor 25 is connected to the buzzer 26.

[0037] In this invention, the distance sensor 25 detects the distance between the top of the piston plate 18 and the distance sensor 25 in real time. When the piston plate 18 is about to move to the inner bottom wall of the material box 3, the paint is about to be consumed. At this time, the value detected by the distance sensor 25 will be greater than the preset threshold. The distance sensor 25 will send a signal to the buzzer 26, and the buzzer 26 will be activated to sound an alarm, thereby reminding the workers to add paint in time or replace the material box 3.

[0038] Please see Figure 4 The inner wall of the material box 3 is fixedly connected to the mounting plate 27, and the bottom of the mounting plate 27 is fixedly connected to the sealing gasket 28.

[0039] In this invention, when adding paint to the material box 3, the user continuously tightens the mounting block 6, which rises along the threaded hole 4. The mounting block 6 then moves the discharge pipe 7 upward, and the discharge pipe 7 moves upward and comes into close contact with the bottom of the sealing gasket 28, thereby achieving a sealing effect on the top of the discharge pipe 7. Then, the user opens the valve on the feeding pipe 10, and paint can be added to the material box 3 through the feeding pipe 10. There is no need to use a plug to seal the threaded hole 4 or the through hole 5, and paint can be added directly, effectively improving the efficiency of adding paint.

[0040] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
