Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, specifically a metal valve spray painting equipment. Background Technology

[0002] Valves are used to control the flow of various types of fluids, including air, water, steam, corrosive media, slurry, oil, liquid metals, and radioactive media. Valves are control components in pipeline fluid transport systems, used to change the cross-sectional area of ​​the passage and the direction of media flow, and have functions such as guiding, stopping, throttling, checking for backflow, diverting flow, or overflowing and relieving pressure. For valves made of metal, rust-preventive paint must be applied to the valve surface to prevent rusting.

[0003] The painting equipment includes a workbench, a fixing device, a painting device, and a rotating device. The metal valve is placed on the workbench and fixed by the fixing device. At the same time, the rotating device and the painting device are turned on. The painting device sprays paint on the surface of the metal valve, and the rotating device drives the metal valve to rotate at a constant speed. While the metal valve is rotating, the painting device completes the painting on the circumference of the metal valve.

[0004] Existing painting equipment requires complex mechanical structures and multiple painting processes to achieve a uniform paint finish. This results in long processing times, poor mobile painting performance, and damage to the paint surface during loading and unloading, affecting the painting quality of metal valves. Therefore, a metal valve painting device is proposed to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, existing painting equipment requires complex mechanical structures and multiple painting processes to achieve a uniform paint surface, resulting in long processing times, complex equipment, and high costs. This utility model proposes a metal valve painting equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The metal valve spraying equipment of this utility model includes a box body, a fixed seat is fixedly installed on the top of the box body, and a through hole is opened on the top of the fixed seat. A hydraulic cylinder is fixedly installed on the top of the fixed seat, and the piston rod of the hydraulic cylinder passes through the through hole. Five sliding holes are opened on the top of the box body. An installation plate is provided inside the box body. Sliding rods are fixedly installed at the four corners of the upper part of the installation plate. The sliding rods are slidably installed on the top of the box body through the sliding holes. The installation plate is fixedly installed on the top of the piston rod of the hydraulic cylinder. The piston rod slides in the sliding hole. A rotating shaft is rotatably installed on the installation plate through a bearing. A rotating wheel is fixedly installed on the upper end of the rotating shaft. A first fixed plate is fixedly installed on the lower end of the rotating shaft. A motor box is fixedly installed on the lower part of the installation plate. A rotating motor is fixedly installed in the motor box. The rotating shaft of the rotating motor passes through the installation plate, and a transmission wheel is fixedly installed at the front end. The transmission wheel and the rotating wheel rotate through a belt.

[0007] A roller frame is provided below the first fixed plate. Rotating rollers are rotatably mounted on both ends of the roller frame via bearings. The two rotating rollers rotate in conjunction with a conveyor belt. A motor bracket is fixedly mounted on one side of the roller frame, and a conveyor motor is fixedly mounted on the motor bracket. One end of the front roller of the rotating roller is fixedly connected to the rotating shaft of the conveyor motor via a coupling. Multiple fixed shafts are sequentially fixedly mounted on the upper part of the conveyor belt, and a second fixed plate is rotatably mounted on each fixed shaft. A fixed plate is fixedly mounted on one side of the roller frame, and a cylinder is fixedly mounted on the lower part of the fixed plate. The piston rod of the cylinder passes through the fixed plate, and a paint gun is fixedly mounted at its front end. When painting the metal valve, the metal valve is placed on the second fixed plate of the conveyor belt. As the conveyor belt moves to directly below the first fixed plate and stops, the first fixed plate descends to clamp the metal valve with the second fixed plate. The paint gun is then activated to paint the metal valve, and simultaneously, the rotating motor is activated, causing the rotating shaft to drive the metal valve to rotate at a uniform speed, painting its circumference and ensuring even painting of the metal valve surface.

[0008] Preferably, the housing is divided into two parts: the front part is a spray painting chamber and the rear part is a baking chamber. Heating wires are fixedly installed on both sides of the inner wall of the baking chamber. After the metal valve is sprayed, it enters the baking chamber under the drive of the conveyor belt and is baked by the heating wires, so that the paint on the surface of the metal valve dries quickly.

[0009] Preferably, the spray booth of the housing has an installation hole on one side, and a duct is fixedly installed in the installation hole. An exhaust fan is fixedly installed at the opening of the duct. When the metal valve is spraying paint in the spray booth, the paint sprayed by the paint gun will spill into the spray booth. The exhaust fan collects the spilled paint in the spray booth into the duct.

[0010] Preferably, the bottom of the air duct has an air hole, and an air pipe is fixedly installed on the outside of the air hole. An air compressor is connected to the lower end of the air pipe, and the air outlet of the air compressor is connected to an air outlet pipe. The outlet of the air outlet pipe is placed at the bottom of a water tank filled with water. The air compressor compresses the paint exhaust gas in the air duct and injects it into the water in the water tank through the pipe for exhaust gas treatment.

[0011] Preferably, a support plate is fixedly installed in the center of the roller frame. The support plate is located directly below the first fixed plate. When the first fixed plate and the second fixed plate fix the metal valve, the support plate supports the conveyor belt and prevents the conveyor belt from deforming.

[0012] Preferably, the slide bar is convex, with a boss at the bottom. The height of the boss is greater than the height of the rotating wheel above the mounting plate. When the hydraulic cylinder lifts the mounting plate upward, the installation stops when the slide bar boss contacts the inner wall of the top of the box, preventing the rotating wheel from colliding with the inner wall of the top of the box.

[0013] The advantages of this utility model are:

[0014] 1. This utility model involves placing a metal valve on a second fixed plate, starting a conveyor motor, and rotating rollers driving a conveyor belt under the action of a coupling. When the metal valve moves directly below the first fixed plate, the conveyor motor stops, the hydraulic cylinder is activated, and the mounting plate is pushed to lower the first fixed plate at the lower end of the rotating shaft until it is fixed to the second fixed plate under the action of a receiving plate. Simultaneously, the paint gun and rotating motor are turned on, and while the paint gun sprays paint on the surface of the metal valve, the rotating shaft rotates under the cooperation of the transmission wheel and the rotating wheel on the belt. At the same time, the first fixed plate drives the metal valve to rotate, completing the structural design of painting the surface of the metal valve. This design achieves the function of uniformly spraying paint on the surface of the metal valve, solving the problems of existing painting devices that require complex mechanical structures and multiple painting processes to achieve a uniform paint surface, resulting in long processing time, complex equipment, and high costs. This design improves the painting efficiency of metal valves. Attached Figure Description

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 scope of protection of the present utility model.

[0023] Please see Figure 1-5 As shown, a metal valve painting device includes a housing 1. A fixing seat 4 is fixedly installed on the top of the housing 1, and the fixing seat 4 has a through hole on its top. A hydraulic cylinder 2 is fixedly installed on the top of the fixing seat 4, and the piston rod of the hydraulic cylinder 2 passes through the through hole. Five sliding holes are opened on the top of the housing 1. An installation plate 15 is provided inside the housing 1. Sliding rods 3 are fixedly installed at the four corners of the upper part of the installation plate 15. The sliding rods 3 are slidably installed on the top of the housing 1 through the sliding holes. The installation plate 15 is fixedly installed on the hydraulic cylinder 2. The piston rod slides within a sliding hole at its top. A rotating shaft 18 is rotatably mounted on the mounting plate 15 via bearings. A rotating wheel 16 is fixedly mounted on the upper end of the rotating shaft 18, and a first fixed plate 19 is fixedly mounted on the lower end of the rotating shaft 18. A motor housing is fixedly mounted on the lower part of the mounting plate 15, and a rotating motor 21 is fixedly mounted inside the motor housing. The rotating shaft of the rotating motor 21 passes through the mounting plate 15, and a transmission wheel 17 is fixedly mounted on its front end. The transmission wheel 17 and the rotating wheel 16 rotate in cooperation with each other via a belt 20.

[0024] A roller frame 5 is provided below the first fixed plate 19. Rotary rollers 26 are rotatably mounted on both ends of the roller frame 5 via bearings. The two rotating rollers 26 rotate in coordination with each other via a conveyor belt 6. A motor bracket is fixedly mounted on one side of the roller frame 5, and a conveyor motor 7 is fixedly mounted on the motor bracket. One end of the front roller of each rotating roller 26 is fixedly connected to the rotating shaft of the conveyor motor 7 via a coupling 8. Multiple fixed shafts 22 are sequentially fixedly mounted on the upper part of the conveyor belt 6, and a second fixed plate 9 is rotatably mounted on each fixed shaft 22. A fixed plate is fixedly mounted on one side of the roller frame 5, and a cylinder 14 is fixedly mounted on the lower part of the fixed plate. The piston rod of the cylinder 14 passes through the fixed plate, and a paint spray gun 13 is fixedly mounted at its front end. During operation, the metal valve painting process requires multiple steps. When changing the working position of the metal valve, paint damage can easily occur. To ensure the painting effect, the metal valve is placed on the second fixed plate 9, and the conveyor motor 7 is started, driving the rotating rollers 26 to rotate via the coupling 8. Simultaneously, the conveyor belt 6 starts running, and under the action of the conveyor belt 6, the metal valve is transported to directly below the first fixed plate 19. The conveyor motor 7 stops, the hydraulic cylinder 2 is started, and the mounting plate 15 is pushed downward until the first fixed plate 19 and the second fixed plate 9 at the lower end of the rotating shaft 18 clamp the metal valve under the action of the receiving plate 25 and the fixed shaft 22. At the same time, the paint gun 13 and the rotating motor 21 are started. The paint gun 13 sprays paint on the surface of the metal valve. At the same time, under the action of the rotating motor 21, the transmission wheel 17 drives the rotating wheel 16 to rotate through the belt 20. At the same time, the rotating shaft 18 drives the first fixed plate 19 to rotate at a constant speed. The first fixed plate 19 and the second fixed plate 9 drive the metal valve to rotate at a constant speed, completing the painting of one circle of the metal valve surface. The height of the nozzle of the paint gun 13 is adjusted by the cylinder 14 to complete the overall painting operation of the metal valve surface, making the paint surface of the metal valve surface uniform. Then, the piston rod of the hydraulic cylinder 2 retracts, pulling the mounting plate 15 upward to release the fixing of the metal valve. The conveyor motor 7 is started to carry out painting.

[0025] The housing 1 is divided into two parts: the front part is the spray painting chamber and the rear part is the baking chamber. Heating wires 23 are fixedly installed on both sides of the inner wall of the baking chamber. During operation, after the metal valve is sprayed, it enters the baking chamber under the drive of the conveyor belt 6 and is baked by the heating wires 23, so that the paint on the surface of the metal valve dries quickly.

[0026] The spray booth of the housing 1 has an installation hole on one side, and a duct 10 is fixedly installed in the installation hole. An exhaust fan 24 is fixedly installed at the opening of the duct 10. When the metal valve is spraying paint in the spray booth, the paint sprayed by the paint gun 13 will spill into the spray booth. The exhaust fan 24 collects the spilled paint in the spray booth into the duct 10.

[0027] The bottom of the air duct 10 has an air hole, and an air pipe is fixedly installed on the outside of the air hole. An air compressor 11 is connected to the lower end of the air pipe, and an air outlet pipe is connected to the air outlet of the air compressor 11. The outlet of the air outlet pipe is placed at the bottom of a water tank 12 filled with water. During operation, the air compressor 11 compresses the paint exhaust gas in the air duct 10 and injects it into the water in the water tank 12 through the pipe for exhaust gas treatment, so as to avoid the exhaust gas from polluting the environment.

[0028] A support plate 25 is fixedly installed in the center of the roller frame 5, and the support plate 25 is located directly below the first fixed plate 19. During operation, when the first fixed plate 19 and the second fixed plate 9 fix the metal valve, the support plate 25 supports the conveyor belt 6 to prevent the conveyor belt 6 from deforming.

[0029] The slide bar 3 is convex, with a boss at the bottom. The height of the boss is greater than the height of the rotating wheel 16 above the mounting plate 15. During operation, when the hydraulic cylinder 2 lifts the mounting plate 15 upward, the mounting plate 15 is lifted until the boss of the slide bar 3 contacts the inner wall of the top of the box 1 and stops, preventing the rotating wheel 16 from colliding with the inner wall of the top of the box 1.

[0030] Working principle: The metal valve is placed on the second fixed plate 9. The conveyor motor 7 is started, driving the rotating roller 26 to rotate via the coupling 8. Simultaneously, the conveyor belt 6 starts running, transporting the metal valve to directly below the first fixed plate 19. The conveyor motor 7 stops, and the hydraulic cylinder 2 is activated, pushing the mounting plate 15 downwards until the first and second fixed plates 9 at the lower end of the rotating shaft 18 clamp the metal valve under the action of the receiving plate 25 and the fixed shaft 22. At the same time, the paint gun 13 and the rotating motor 21 are started. The paint gun 13 sprays paint on the surface of the metal valve. Simultaneously, under the action of the rotating motor 21, the transmission wheel 17 drives the rotating wheel 16 to rotate via the belt 20. At the same time, the rotating shaft 18 drives the first fixed plate 19 to rotate at a constant speed. The first and second fixed plates 19 drive the metal valve to rotate at a constant speed, completing the painting of one circumference of the metal valve surface. The height of the nozzle of the paint gun 13 is adjusted by the cylinder 14 to complete the overall painting operation of the metal valve surface, making the paint surface of the metal valve uniform. When the metal valve is being painted in the spray booth, the paint sprayed by the paint gun 13 will spill into the spray booth. The exhaust fan 24 collects the spilled paint in the air duct 10. The air compressor 11 compresses the paint exhaust gas in the air duct 10 and injects it into the water in the water tank 12 through the pipeline for exhaust gas treatment to avoid pollution of the environment. Then, the piston rod of the hydraulic cylinder 2 retracts, pulling the mounting plate 15 upward to release the metal valve. When the hydraulic cylinder 2 lifts the mounting plate 15 upward, the mounting plate 15 is raised to... When the boss of slide rod 3 contacts the inner wall of the top of box 1, it stops to prevent the rotating wheel 16 from colliding with the inner wall of the top of box 1. The conveyor motor 7 is started, and the painted metal valves move forward. The metal valves behind move downwards to the first fixed plate 19 for painting. After the metal valves are painted, they enter the baking chamber under the drive of the conveyor belt 6 and are baked by the electric heating wire 23 to make the paint on the surface of the metal valves dry quickly. When all the paint on the metal valves of the same batch has passed through the baking chamber, the power of the painting equipment is turned off, and the painting work is completed.
