Description

Technical Field

[0001] The utility model relates to a spraying device, in particular to an insulating paint spraying device. Background Technique

[0002] Insulating paint is a paint with excellent electrical insulation. It has good electrical, thermal, mechanical and chemical properties. Most are varnishes, and there are also colored paints. Insulating paints are divided into solvent-based ones with a temperature resistance below 600 °C and water-based ones with a temperature resistance of 600 - 1700 °C, and are used for coating the surface of objects to be protected or decorated. This paint can form a ceramic coating with a relatively high volume resistivity on the surface of the object to be painted, which can withstand a strong electric field without being broken down. This coating has relatively high mechanical strength and good chemical stability, and is resistant to aging, water, and chemical corrosion. The insulating layer can be used to improve the insulation performance of electrical equipment, prevent current leakage and short circuits, and is mostly used for spraying on the surface of wires and cables.

[0003] The principle of insulating coating spraying is to use spraying equipment to spray insulating materials onto the surface to be treated to form an insulating layer. The existing spraying devices are inconvenient to adjust the position of the spray head during spraying, resulting in the inability to ensure the uniformity of insulating paint spraying when spraying workpieces of different sizes, and when spraying large-area workpieces, the insulating paint splashes everywhere, which is easy to cause waste.

[0004] Therefore, we need to design such an insulating paint spraying device. Content of the Utility Model

The left and right sides inside the housing are divided into a spraying chamber and a drying chamber. There is an inlet on the left side of the housing and an outlet on the right side of the housing. A circular hole is opened in the middle inside the housing. The spraying chamber and the drying chamber are connected. A wind guide plate is fixedly connected to the middle inside the drying chamber, and there are multiple ventilation circular holes on the wind guide plate. A support frame is fixedly connected to the top of the housing, and a liquid storage tank is fixedly connected to the top of the support frame. A controller is installed on the front side of the liquid storage tank. The bottom of the liquid outlet pipe at the lower part of the liquid storage tank is fixedly connected to a telescopic hose. A solenoid valve I is installed on the liquid outlet pipe at the lower part of the liquid storage tank. The bottom of the telescopic hose is fixedly connected to an annular spraying machine. The annular spraying machine is located in the spraying chamber. Both the solenoid valve I and the annular spraying machine are electrically connected to the controller. Transmission mechanisms are arranged on the outer sides of the left and right parts of the housing.

The wire feeding wheel is rotatably connected to the left side of the housing, the wire winding wheel is rotatably connected to the right side of the housing, and a servo motor is fixedly connected to the fixing plate on the front side of the wire winding wheel. The output shaft of the servo motor is connected to the wire winding wheel, and the servo motor is electrically connected to the controller.

[0008] Further, it further includes a blocking block. There is a liquid inlet on the liquid storage tank, and a blocking block is slidably connected at the liquid inlet.

[0009] Further, it further includes a connecting block and an electric push rod. A rounded rectangular opening is formed at the top of the housing. The upper part of the annular spraying machine passes through the housing, and the upper part of the annular spraying machine slides at the rounded rectangular opening. A connecting block is fixedly sleeved on the annular spraying machine, and the connecting block slides on the top of the housing. An electric push rod is fixedly connected to the top of the housing, and the telescopic rod of the electric push rod is fixedly connected to the connecting block. The electric push rod is electrically connected to the controller.

[0010] Further, it further includes a water pump, a connecting pipe and a solenoid valve II. The water pump is fixedly connected to the bottom of the air drying cavity. The water pump is connected and communicated with a connecting pipe, and the connecting pipe is communicated with the liquid outlet pipe at the lower part of the liquid storage tank and the telescopic hose. A solenoid valve II is installed on the connecting pipe, and both the water pump and the solenoid valve II are electrically connected to the controller.

[0011] Further, it further includes a breathable partition board, a double-shaft motor, bevel gear I, a connecting rod, bevel gear II and a fan blade. There is a rectangular opening at the upper part of the housing, and a breathable partition board is slidably connected at the rectangular opening. A double-shaft motor is fixedly connected to the breathable partition board. The output shafts of the double-shaft motor are fixedly connected with bevel gear I. Two connecting rods are rotatably connected to the breathable partition board. A bevel gear II is fixedly connected to the top of each connecting rod. Bevel gear I meshes with bevel gear II.

The left and right sides inside the housing 1 are divided into the spraying chamber 101 and the drying chamber 102. There is an inlet on the left side of the housing 1 and an outlet on the right side of the housing 1. A circular hole is opened in the middle of the inside of the housing 1. The spraying chamber 101 and the drying chamber 102 are communicated. A wind guiding plate 104 is fixedly connected in the middle of the drying chamber 102. There are a plurality of ventilation circular holes on the wind guiding plate 104. Two front and rear support frames 2 are symmetrically welded on the top of the left side of the housing 1. A liquid storage tank 3 is welded on the top of the four support frames 2. A controller 20 is installed by screwing at the middle position on the front side of the liquid storage tank 3. The bottom of the liquid outlet pipe at the lower part of the liquid storage tank 3 is threadedly connected with a telescopic hose 4. A solenoid valve I 5 is installed on the liquid outlet pipe at the lower part of the liquid storage tank 3. The bottom of the telescopic hose 4 is threadedly connected with an annular spraying machine 6. A plurality of high-speed nozzles are installed circumferentially on the annular spraying machine 6. The annular spraying machine 6 is located in the spraying chamber 101. Both the solenoid valve I 5 and the annular spraying machine 6 are electrically connected to the controller 20. A transmission mechanism is provided on the outer sides of the left and right parts of the housing 1.

[0025] As Figure 1 , Figure 2 and Figure 6 shown, it further includes a transmission mechanism. The transmission mechanism includes a wire feeding wheel 17, a wire winding wheel 18, and a servo motor 19. The wire feeding wheel 17 is rotatably connected to the left side of the housing 1. The wire winding wheel 18 is rotatably connected to the right side of the housing 1. A servo motor 19 is bolted on the fixing plate on the front side of the wire winding wheel 18. The output shaft of the servo motor 19 is connected to the wire winding wheel 18. The servo motor 19 is electrically connected to the controller 20.

[0026] As Figure 1 , Figure 2 and Figure 4 shown, it further includes a blocking block 301. There is a liquid inlet on the left front side of the liquid storage tank 3. The blocking block 301 is threadedly connected at the liquid inlet.

[0027] As Figure 3 and Figure 6 shown, it further includes a connecting block 7 and an electric push rod 8. A rounded rectangular opening is opened on the left side of the top of the housing 1. The upper part of the annular spraying machine 6 passes through the housing 1 from the rounded rectangular opening. The upper part of the annular spraying machine 6 slides at the rounded rectangular opening. The upper part of the annular spraying machine 6 is fixedly sleeved with a connecting block 7. The connecting block 7 slides on the left side of the top of the housing 1. An electric push rod 8 is bolted on the right side of the top of the housing 1. The telescopic rod of the electric push rod 8 is fixedly connected to the connecting block 7. The electric push rod 8 is electrically connected to the controller 20.

[0028] When it is necessary to spray insulating paint on wires or cables using this device, first, place the unsprayed wire reel or cable reel on the wire feeding wheel 17, pull out one end of the wire reel or cable reel and place it on the wire take-up wheel 18. Then, rotate and unscrew the plug block 301, fill the liquid storage tank 3 with insulating paint, rotate and close the plug block 301, start the servo motor 19 through the controller 20. The output shaft of the servo motor 19 drives the wire take-up wheel 18 to rotate, thereby pulling the wire feeding wheel 17 to automatically convey the unsprayed wire or cable into the housing 1 for spraying and air drying. Then, open the solenoid valve I 5, start the electric push rod 8 and the annular spraying machine 6 through the controller 20. The telescopic rod of the electric push rod 8 drives the connecting block 7 to move left and right, thereby driving the annular spraying machine 6 to spray left and right. Limited by the rounded rectangular opening on the left side of the top of the housing 1, the annular spraying machine 6 can only move within the range of the spraying chamber 101. The annular spraying machine 6 sprays the wire and cable in a surrounding manner with multiple high-speed nozzles distributed circumferentially. The combination of the two methods realizes the all-round spraying of the wire and cable, and spraying in the spraying chamber 101 can avoid waste caused by splashing everywhere.

[0029] As Figure 1 and Figures 4-7 shown, it also includes a breathable partition 103, a dual-axis motor 12, bevel gear I 13, a connecting rod 14, bevel gear II 15 and a fan blade 16. There is a rectangular opening on the upper right side of the housing 1, and a breathable partition 103 is bolted at the rectangular opening. The breathable partition 103 is located directly above the air drying chamber 102. A dual-axis motor 12 is bolted to the top of the breathable partition 103. The output shafts of the dual-axis motor 12 are fixedly connected with bevel gear I 13. The left and right sides of the breathable partition 103 are rotatably connected with connecting rods 14. The tops of the two connecting rods 14 are fixedly connected with bevel gear II 15. Bevel gear I 13 meshes with bevel gear II 15. The lower parts of the two connecting rods 14 penetrate into the air drying chamber 102, and the tops of the two connecting rods 14 are fixedly connected with fan blades 16. The fan blades 16 are located above the air guiding plate 104.

[0030] The sprayed wire and cable are pulled into the air drying chamber 102. Start the dual-axis motor 12 through the controller 20. The output shafts of the dual-axis motor 12 drive the two bevel gear I 13 to rotate. Bevel gear II 15 meshes with bevel gear I 13. Bevel gear II 15 drives the two connecting rods 14 to rotate, thereby driving the two fan blades 16 to rotate simultaneously to air dry the sprayed wire or cable. The wind fanned by the fan blades 16 is evenly blown out through the air guiding plate 104, avoiding unevenness on the surface of the insulating coating of the wire and cable due to air drying. The sprayed and air-dried wire and cable are pulled and collected by the wire take-up wheel 18.

[0031] After a roll of wire or cable is sprayed and air-dried, first, the solenoid valve I 5, the annular spraying machine 6, and the electric push rod 8 are closed through the controller 20. The annular spraying machine 6 no longer sprays the insulating paint, and the telescopic rod of the electric push rod 8 no longer drives the connecting block 7 and the annular spraying machine 6 to move. Subsequently, the servo motor 19 is closed through the controller 20, and the fan blade 16 stops rotating. After the wire and cable that has been sprayed and air-dried is wound up by the take-up reel 18, the servo motor 19 is closed through the controller 20, and the output shaft of the servo motor 19 no longer drives the take-up reel 18 to rotate.

[0032] As Figure 2 and Figure 4 shown, it further includes a water pump 9, a connecting pipe 10, and a solenoid valve II 11. The water pump 9 is bolted to the right side of the inner bottom of the air-drying chamber 102. The top of the water pump 9 is connected and communicated with the connecting pipe 10. The connecting pipe 10 communicates with the liquid outlet pipe at the lower part of the liquid storage tank 3 and the telescopic hose 4. The solenoid valve II 11 is installed on the upper part of the connecting pipe 10. Both the water pump 9 and the solenoid valve II 11 are electrically connected to the controller 20.

[0033] During and after spraying, the excess insulating paint falls along the inner wall of the spraying chamber 101 to the inner bottom of the air-drying chamber 102. The water pump 9 is started and the solenoid valve II 11 is opened through the controller 20. The water pump 9 pumps the excess insulating paint accumulated at the inner bottom of the air-drying chamber 102 into the liquid storage tank 3 for spraying again, recycling the excess insulating paint. When all the excess insulating paint accumulated at the inner bottom of the air-drying chamber 102 is pumped out, the water pump 9 and the solenoid valve II 11 are closed through the controller 20, and the pumping stops.
