Description

Technical Field

[0001] This utility model belongs to the technical field of spray painting equipment, and specifically relates to a spray painting equipment that can spray paint evenly. Background Technology

[0002] Currently, most spray painting equipment on the market expands the spray coverage area by configuring multiple sets of nozzles and uses a workpiece conveying mechanism to automatically transfer the workpiece during the spraying process, thus achieving automated spray painting of the workpiece surface. However, in practical applications, the difficulty in precisely controlling the internal pressure of each nozzle can easily lead to differences in the amount of paint sprayed, resulting in uneven spraying. For example, in large-area spraying scenarios, some areas may experience excessive paint and drip defects due to excessive nozzle pressure, while other areas may suffer from insufficient paint coverage due to insufficient pressure, seriously affecting the product appearance quality and production efficiency.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 12 As shown, a uniform spraying device includes a base plate 1. A first U-shaped bracket 2 is fixedly connected to the upper surface of the base plate 1. An electric push rod 3 is fixedly connected to the inner wall of the first U-shaped bracket 2. A rectangular dispensing box 4 is fixedly connected to the bottom of the electric push rod 3. A first rectangular hole 5 is opened on the upper surface of the rectangular dispensing box 4. A rectangular cylinder 6 is fixedly connected to both the inner wall of the first rectangular hole 5 and the inner wall of the rectangular dispensing box 4. A first sealing plate 7 is fixedly connected to both the front and rear sides of the rectangular cylinder 6 and the inner wall of the rectangular dispensing box 4. A second sealing plate 8 is fitted against the inner wall of the rectangular cylinder 6. A connecting block 9 is fixedly connected to the upper surface of the second sealing plate 8. A spring 10 is fixedly connected to the upper surface of the connecting block 9. The upper surface of the spring 10 and the upper surface of the rectangular dispensing box 4 are connected to the connecting block 9. A second U-shaped bracket 11 is fixedly connected to each side. A second rectangular hole 12 is opened on the left side of the rectangular cylinder 6, and a first circular hole 13 is opened on the right side of the rectangular cylinder 6. A second circular hole 14 is opened at the bottom of the rectangular dispensing box 4. A bent pipe 15 is fixedly connected to the inner wall of the first circular hole 13 and the inner wall of the second circular hole 14. A solenoid valve 16 is fixedly connected to the bottom of the bent pipe 15. A vertical pipe 17 is fixedly connected to the bottom end of the solenoid valve 16. A nozzle 18 is fixedly connected to the bottom end of the vertical pipe 17. A conveyor 19 is fixedly connected to the upper surface of the base plate 1. A paint spray pump 20 is fixedly connected to the upper surface of the base plate 1. A connecting hose 21 is fixedly connected to the outlet end of the paint spray pump 20 and the back of the rectangular dispensing box 4. An inlet pipe 22 is fixedly connected to the inlet end of the paint spray pump 20.

[0032] The first U-shaped bracket 2 has a third circular hole 32 on its upper surface, and the second U-shaped bracket 11 has a guide post 33 fixedly connected to its upper surface. The guide post 33 has a guide sleeve 34 fitted on its surface, and the surface of the guide sleeve 34 is fixedly connected to the inner wall of the third circular hole 32.

[0033] It should be noted that the electric push rod 3 can control the distance between the nozzle 18 and the conveyor 19 according to the shape of the workpiece to be sprayed. Through the cooperation of the guide column 33 and the guide sleeve 34, the rectangular liquid distribution box 4 can only move up and down. The conveyor 19 can transport the workpiece to be sprayed from the left side of the nozzle 18 to the right side of the nozzle 18. When the workpiece to be sprayed passes under the nozzle 18, the paint sprayed by the nozzle 18 can be used to spray paint the surface of the workpiece.

[0034] The first sealing plate 7 ensures that the paint in the rectangular dispensing box 4 can only enter the rectangular cylinder 6 through the rectangular hole. The spring force of the spring 10 causes the second sealing plate 8 to be resisted when it moves upward. After the paint enters the rectangular cylinder 6, the pressure of the paint in the rectangular dispensing box 4 increases, which causes the paint to exert an upward thrust on the second sealing plate 8, causing the second sealing plate 8 to move upward. When the upward thrust of the paint in the rectangular cylinder 6 on the second sealing plate 8 reaches a specified magnitude, multiple bends 15 on the right side of the rectangular cylinder 6 will be opened simultaneously, allowing the paint in the rectangular cylinder 6 to enter each bend 15 evenly. At this time, the amount of paint sprayed by each nozzle 18 is the same, thus achieving uniform painting and improving the painting quality. At the same time, by controlling the opening and closing of the solenoid valve 16, the number of nozzles 18 opened on the painting device can be adjusted according to the shape of different workpieces, and the painting range of the painting device can be changed.

[0035] like Figures 1 to 13 As shown, a third rectangular hole 23 is provided on the left side of the rectangular separator 4. A U-shaped plate 24 is attached to the inner wall of the third rectangular hole 23 and the left side of the rectangular cylinder 6. A fourth rectangular hole 25 is provided on the right side of the U-shaped plate 24. A filter screen 26 is fixedly connected to the inner wall of the fourth rectangular hole 25. A third sealing plate 27 is fixedly connected to the left side of the U-shaped plate 24. An installation hole 28 is provided inside the third sealing plate 27. A threaded hole 29 is provided on the left side of the rectangular separator 4. A bolt 30 is attached to the inner wall of the installation hole 28 and the left side of the third sealing plate 27. The inner wall of the bolt 30 is threadedly connected to the surface of the threaded hole 29.

[0036] The fourth rectangular hole 25 is located to the left of the second rectangular hole 12, the first round hole 13 is located to the right of the second rectangular hole 12, the inner wall of the rectangular liquid separator 4 is fixedly connected to a sealing block 31, the sealing block 31 is located to the right of the threaded hole 29, the filter screen 26 is a stainless steel mesh, and the pore size of the filter screen 26 is 0.2mm.

[0037] It should be noted that the third sealing plate 27 can seal the third rectangular hole 23, and the sealing block 31 can prevent paint from entering the connection between the bolt 30 and the threaded hole 29. Through the cooperation of the third sealing plate 27, the mounting hole 28, the threaded hole 29 and the bolt 30, the filter screen 26 can be fixed on the left side of the rectangular tube 6. After the filter screen 26 is fixed on the left side of the rectangular tube 6, the filter screen 26 can effectively intercept the clumps of paint, avoiding the clogging of the nozzle 18 and uneven paint output.

[0038] The working principle of this utility model is as follows: First, connect the pipe on the paint storage tank to the inlet pipe 22. Then, place the workpiece to be sprayed on the conveyor 19, and the conveyor 19 transports the workpiece to be sprayed from the left side of the nozzle 18 to the right side of the nozzle 18. When the workpiece is about to pass under the nozzle 18, turn on the paint pump 20, so that the paint in the paint storage tank enters the rectangular dispensing box 4 through the inlet pipe 22, the paint pump 20, and the connecting hose 21 in sequence. Then, the filter screen 26 intercepts the clumps of paint, and the filtered paint enters the rectangular cylinder 6 through the rectangular holes. At this time, as the rectangular cylinder 6... The increased pressure of the paint in the rectangular tube 6 causes the paint to exert an upward thrust on the second sealing plate 8, causing the second sealing plate 8 to move upward. When the upward thrust of the paint in the rectangular tube 6 on the second sealing plate 8 reaches a specified value, multiple bends 15 on the right side of the rectangular tube 6 will be opened simultaneously, allowing the paint in the rectangular tube 6 to enter each bend 15 evenly. At this time, the amount of paint sprayed from each nozzle 18 will be the same. Then, when the workpiece to be painted passes under the nozzle 18, the paint sprayed from the nozzle 18 can be used to paint the surface of the workpiece.

[0039] When cleaning the filter screen 26, first drain the paint from the rectangular separator 4. Then, remove the filter screen 26 by unscrewing the bolt 30 from the threaded hole 29. When installing the filter screen 26, first insert the U-shaped plate 24 into the third rectangular hole 23 and make the third sealing plate 27 fit against the left side of the rectangular separator 4. Then, insert the bolt 30 into the mounting hole 28 and screw the bolt 30 into the threaded hole 29. At this time, the filter screen 26 can be fixed on the left side of the rectangular cylinder 6 by the cooperation of the bolt 30, the threaded hole 29, the mounting hole 28 and the third sealing plate 27, and the third rectangular hole 23 is sealed by the third sealing plate 27.
