Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion coating spraying, and in particular to a magnesium alloy anti-corrosion coating spraying equipment. Background Technology

[0002] Spraying equipment is a product of the reform and opening up, and of the increasing automation in industrial technology. With the increasing level of automation, spraying production lines are being used more and more widely, penetrating into many sectors of the national economy. Anti-corrosion coatings are applied to metal surfaces to isolate the metal from the surrounding environment, possessing good electrical insulation and water resistance.

[0003] However, when using traditional anti-corrosion coating spraying equipment, sediment will form due to the prolonged static state of the anti-corrosion material. This sediment may make the material viscous or lumpy. Therefore, a stirring device is set up to stir the sedimented coating. However, the stirred coating will remain inside the equipment after use. If it is not cleaned in time, it may cause equipment blockage. In addition, when the construction personnel hold the spray nozzle, they may hold it too far or too close to the workpiece due to hand tremors, resulting in uneven material thickness distribution. This may lead to insufficient local anti-corrosion performance and failure to form a uniform and effective protective layer. Utility Model Content

An annular sleeve buckle is fixedly connected to the rear end of the nozzle, and a compression spring is fixedly connected to the bottom of the annular sleeve buckle, with the compression spring penetrating and fixedly connected to the inner core of the nozzle.

[0006] As a further description of the above technical solution: the rear end of the nozzle is rotatably connected to an annular sleeve, and L-shaped telescopic rods are fixedly connected to the left and right sides of the annular sleeve. One end of the L-shaped telescopic rod is rotatably connected to a rotating shaft, and rollers are fixedly connected between the rotating shafts.

[0010] As a further description of the above technical solution: a one-way valve is fixedly connected to the air outlet of the air compressor.

[0012] This utility model has the following beneficial effects:

[0013] 1. The present invention proposes a magnesium alloy anti-corrosion coating spraying equipment. First, a cleaning solution tank is installed next to the stirring device at the top of the base. The tank is connected to a water pump through a pipe. After the paint is sprayed, the valve at the stirring device is closed to prevent the paint from flowing out. The valve at the cleaning solution tank is opened so that the water pump can draw out the cleaning solution and discharge it to clean the paint residue inside the connecting hose and the nozzle. After cleaning, the valve at the cleaning solution tank is closed and the air compressor is turned on so that compressed gas enters the pipe to dry the remaining cleaning solution inside, preventing the remaining cleaning solution from affecting the spraying effect of the next time, thus saving cleaning time and effort.

[0014] 2. The magnesium alloy anti-corrosion coating spraying equipment proposed in this utility model is achieved by installing an annular sleeve at the rear end of the nozzle, and installing two L-shaped telescopic rods on both sides of the annular sleeve. The ends of the telescopic rods have rollers fixed on the rotating shaft. After adjusting the length of the telescopic rods, they are fixed by snap-fitting into the slots. When the rollers just contact the workpiece, the distance between the nozzle and the spraying head is exactly the optimal spraying position, so that the thickness of the sprayed material is evenly distributed, forming a continuous, dense and consistent protective layer. This avoids the weak anti-corrosion ability caused by uneven local composition and extends the service life of the protected object. Attached Figure Description

[0023] Reference Figure 1-4This utility model provides an embodiment of a magnesium alloy anti-corrosion coating spraying device, comprising a base 1, a paint tank 2 fixedly connected to the top left side of the base 1, a stirring device 25 and a cleaning solution tank 13 and an air compressor 27 fixedly connected to the top middle of the base 1, a water pump 11 fixedly connected to the top right side of the base 1, a paint pump 7 fixedly connected to the top of the paint tank 2 to provide suction for extracting the sediment at the bottom of the paint tank 2, a suction pipe 22 penetrating and fixedly connected to the bottom of the paint pump 7 to transport the sediment at the bottom, and a fixed connection to the outlet of the paint pump 7. A conveying pipe 8 is provided, with one end of the conveying pipe 8 fixedly connected to the top of the stirring device 25. A motor 9 is fixedly connected to the top of the stirring device 25, and a drive shaft 23 is fixedly connected to the output end of the motor 9. A stirring rod 24 is fixedly connected to the surface of the drive shaft 23. The sediment is conveyed into the stirring device 25, and the rotation of the drive shaft 23 drives the stirring rod 24 on the surface to stir the sediment evenly. A four-way pipe 10 is fixedly connected to the inlet of the water pump 11, and one end of the four-way pipe 10 is connected to the outlet of the stirring device 25 and the outlet of the air compressor 27, respectively. The cleaning solution tank 13 is fixedly connected to the outlet. Two valves 26 are rotatably connected to the top of the four-way pipe 10, and these valves 26 are rotatably connected to the outlet pipe of the stirring device 25 and the outlet pipe of the cleaning solution tank 13. The pipe connects to the water pump 11. After the paint spraying is completed, the valves 26 at the stirring device 25 are closed to prevent further paint flow. The valve at the cleaning solution tank 13 is opened, allowing the water pump 11 to draw out and discharge the cleaning solution to clean the paint residue inside the connecting hose 12 and the nozzle 15. After cleaning, close valve 26 at cleaning solution tank 13 and turn on air compressor 27 to allow compressed gas to enter the pipeline to dry the residual cleaning solution inside, preventing the residual cleaning solution from affecting the next spraying effect. A connecting hose 12 is fixedly connected to the outlet of water pump 11. A nozzle 15 is fixedly connected to one end of the connecting hose 12. A ring-shaped buckle 30 is fixedly connected to the rear end of the nozzle 15. Adjust the angle. A compression spring 31 is fixedly connected to the bottom of the ring-shaped buckle 30 and is fixedly connected to the inner core of the nozzle 15.

[0024] The nozzle 15 is rotatably connected to a ring sleeve 16 at its rear end. L-shaped telescopic rods 17 are fixedly connected to the left and right sides of the ring sleeve 16 to control the distance between the nozzle 15 and the object. A rotating shaft 18 is rotatably connected to one end of the L-shaped telescopic rod 17 to control the rotation of rollers 19. Rollers 19 are fixedly connected between the rotating shafts 18, allowing horizontal or vertical movement on large components. Fixing blocks 33 are fixedly connected to the left and right sides of the outer front end of the L-shaped telescopic rod 17, and rotating shafts 18 are rotatably connected between the fixing blocks 33. L-shaped telescopic rod clips 32 are fixedly connected between the rotating shafts 18, and a compression spring 31 is fixedly connected to the bottom rear end of the L-shaped telescopic rod clips 32. The spring pops out, causing the clips to engage in slots. To adjust the distance, the spring is pressed down, causing the clips to lift and be adjusted to other slots. Push rods 3 are fixedly connected to the front and rear sides of the paint tank 2 for easy pushing. Push wheels 4 are rotatably connected to the lower end of the push rods 3 for easy movement. A paint tank inlet is fixedly connected to the top of the paint tank 2. 6. A cleaning solution inlet 14 is fixedly connected to the top of the cleaning solution tank 13. An air filter 28 is fixedly connected to the air inlet of the air compressor 27 to prevent impurities from clogging the inside of the equipment. A filter 5 is fixedly connected to the outlet of the stirring device 25 to prevent unevenly stirred paint from being discharged and clogging the pipes. A one-way valve 29 is fixedly connected to the air outlet of the air compressor 27 to prevent backflow. A telescopic rod slot 20 is opened on the top of the inner rod of the L-shaped telescopic rod 17, and the telescopic rod slot 20 is engaged with the front end of the L-shaped telescopic rod buckle 32 to achieve a fixing effect. An annular sleeve 16 has an annular sleeve slot 21 at the up, down, left, and right rotation points, and the annular sleeve slot 21 is slidably connected with the annular sleeve buckle 30, so that the annular sleeve 16 can be fixed in four directions. This prevents the construction personnel from holding the spray nozzle too far or too close to the workpiece due to hand tremors, which may result in uneven material thickness distribution and insufficient local anti-corrosion performance, making it impossible to form a uniform and effective protective layer.

[0025] Working principle: When the equipment is not used for a long time, the paint in the paint tank 2 will settle at the bottom due to prolonged use. The paint pump 7 at the top of the paint tank 2 will suck out the paint through the suction pipe 22 and transport it to the mixing device 25 through the conveying pipe 8. The output end of the motor 9 at the top of the mixing device 25 will rotate, driving the internal drive shaft 23. The drive shaft 23 will rotate, driving the surface stirring rod 24 to stir the settled paint. The stirred paint will then be transported to the water pump 11 through the conveying pipe 8 connected to the four-way pipe 10. The water pump 11 will apply pressure and pass through the flexible... Pipe 12 delivers the material to nozzle 15. Adjusting the annular sleeve 16 at the rear end of nozzle 15 adjusts whether the L-shaped telescopic rods 17 on both sides are horizontal or vertical. Then, rotating the annular sleeve 16, the compression spring 31 inside the nozzle 15 pops out from under the annular sleeve buckle 30, locking the annular sleeve buckle 30 into the annular sleeve groove 21 for fixation. After adjusting the L-shaped telescopic rods 17 to a suitable distance, the L-shaped telescopic rod buckle 31 is popped out by the compression spring 31 at the rear end. The rotating shaft 18 then locks the L-shaped telescopic rod buckle 31 into the telescopic rod groove 20 to fix the distance. When it is necessary to extend the L-shaped telescopic rod 17... 7. When retracting, press the rear end of the L-shaped telescopic rod buckle 31 to retract the compression spring 31 at the bottom, lift the L-shaped telescopic rod buckle 31, and then retract it so that when the roller 19 just contacts the workpiece, the distance of the nozzle 15 is exactly the optimal spraying position, so that the thickness of the sprayed material is evenly distributed. Install a four-way pipe 10 between the feed pipe 8 before the water pump 11, which is connected to the stirring device 25, the cleaning solution tank 13, and the air compressor 27 respectively. Turn the valve 26 at the upper end of the feed pipe 8 at the stirring device 25 to control the discharge and closing of the paint. After using the equipment, turn the valve 26 at the stirring device 25. The valve 26 at the upper end of the feed pipe 8 is closed to supply the paint. The valve 26 at the upper end of the feed pipe 8 connected to the cleaning solution tank 13 is opened. The cleaning solution is drawn out by the water pump 11 and discharged into the nozzle 15 and the connecting hose 12 to clean the paint residue. This prevents the residual paint from drying and clogging the inside of the equipment. After cleaning, the valve 26 is closed and the air compressor 27 is turned on to deliver compressed gas to dry the residual cleaning solution inside the feed pipe 8, the nozzle 15 and the connecting hose 12. This prevents the residual solution from affecting the next spraying effect and achieves the cleaning effect without disassembling the parts.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
