Description

Technical Field

[0001] This utility model belongs to the technical field of paint coating equipment, and relates to a continuous paint coating equipment for the ball head steel foot of a suspension insulator. Background Technology

[0002] In power systems, suspension insulators are key components, and the quality of the protective coating on their ball-head steel feet directly affects the insulator's insulation performance and service life.

[0003] Existing painting equipment is inefficient and cannot meet the needs of large-scale production. Furthermore, it lacks precise adjustment capabilities for paint height and thickness, making it unsuitable for painting ball-end steel feet of different specifications. In the drying stage, traditional methods often employ simple hot air drying, which is inefficient and has low heat utilization. Simultaneously, paint mist and harmful gases generated during the painting process, if not treated promptly, pose a threat to the health of operators and do not comply with environmental protection requirements.

[0004] Therefore, we propose a continuous coating equipment for the ball-head steel feet of suspension insulators, which can complete the continuous coating work for the ball-head steel feet of suspension insulators, and precisely adjust the coating height and thickness, while also having the functions of efficient drying and environmental protection. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a continuous coating device for the ball-head steel feet of suspension insulators. The technical problem to be solved by this utility model is: how to achieve continuous coating of the ball-head steel feet of suspension insulators, and precisely adjust the coating height and thickness, while also possessing efficient drying and environmental protection functions.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A continuous coating device for the ball-head steel foot of a suspension insulator includes a frame, a chain conveyor assembly, an adsorption assembly, a closing assembly, a flat air outlet pipe, two movable coating assemblies, and two hot air circulation assemblies. The chain conveyor assembly is located inside the frame, and the two movable coating assemblies are both located inside the frame and below the chain conveyor assembly. The two hot air circulation assemblies are located on the rear side of the frame, and the adsorption assembly is located behind the frame. The adsorption assembly and the two hot air circulation assemblies are all connected to the interior of the frame. The closing assembly and the flat air outlet pipe are both located on the left side of the frame, and the flat air outlet pipe is located above the closing assembly and is connected to the adsorption assembly.

[0008] The working principle of this utility model is as follows: The ball-head steel foot is placed on the chain conveyor assembly, which then transports the ball-head steel foot to the top of the moving paint-dipping assembly in an orderly manner. The moving paint-dipping assembly contains paint liquid. The ball-head steel foot descends under the drive of the chain conveyor assembly and is immersed in the paint liquid in the moving paint-dipping assembly, thereby achieving uniform paint coating and ensuring that the surface of the ball-head steel foot is fully covered with paint. After the paint coating is completed, the ball-head steel foot continues to move forward under the action of the chain conveyor assembly and enters the hot air circulation drying stage. Two hot air circulation assemblies start working. The hot air circulation assemblies generate hot air through internal heating devices. The hot air is transported to the inside of the frame through pipes. The hot air circulates inside the frame and returns to the inside of the hot air circulation assemblies. The adsorption assembly can adsorb paint mist and harmful gases generated during equipment operation in a timely manner, preventing these pollutants from spreading into the working environment. The closing assembly plays a protective role by sealing the opening on the left side of the frame to prevent hot air leakage and maintain the stability of temperature and airflow inside the frame. The flat air outlet pipe blows an air curtain downward when the closing assembly opens, preventing dust from entering the inside of the frame.

[0009] The frame is a rectangular box with two front doors at the front end. The positions of the two movable paint-applying components correspond to the two front doors respectively. An observation port is opened on the front door, and a transparent acrylic plate is fixed inside the observation port. The upper part of the left side of the frame has loading and unloading ports. A sealing beam is fixed in the middle of the loading and unloading ports. The position of the closing component corresponds to the loading and unloading ports. A U-shaped partition and a horizontal partition are fixed inside the upper part of the frame. The U-shaped opening of the U-shaped partition faces to the right. The horizontal partition is located between the two U-shaped side walls of the U-shaped partition. The U-shaped partition and the horizontal partition divide the space inside the upper part of the frame into a drying channel.

[0010] With the above structure, the front door can be opened, which is convenient for staff to carry out daily maintenance and repair. The observation port allows staff to observe the internal condition of the equipment. The loading and unloading ports are used for loading and unloading materials. The U-shaped partition and the horizontal partition divide the space at the upper part of the frame into a U-shaped space, which improves the space utilization rate and optimizes the flow path of hot air, so that the hot air can fully contact the ball head steel feet.

[0011] The chain conveyor assembly includes two chains symmetrically arranged front and rear. Two sprockets are rotatably mounted at each corner of the drying channel at the upper end of the frame and above the movable paint-applying assembly. The corresponding two sprockets are symmetrically arranged front and rear. One chain engages with several sprockets located in front, and the other chain engages with several sprockets located behind. Two worm gear reducers are fixed on the front and rear sides of the frame. The positions of the worm gear reducers correspond to the positions of two sprockets on the same side, and the output shafts of the worm gear reducers are respectively connected to the rotation shafts of the corresponding sprockets. Two helical gear reducers are fixed on the front and rear sides of the frame. The output shafts of the two helical gear reducers are respectively connected to the input shafts of the two worm gear reducers on the same side. Several crossbars are evenly distributed and fixed between the two chains. Each crossbar has an L-shaped steel foot support plate rotatably mounted on it. The upper end of the vertical part of the L-shape of the steel foot support plate is fitted onto the corresponding crossbar, and the horizontal part of the L-shape of the steel foot support plate faces to the left. Several openings of different sizes are opened at the left end of the horizontal part of the L-shape of the steel foot support plate.

[0012] Using the above structure, the chain is fitted onto the corresponding sprocket, and the ball-head steel foot is placed in the opening of the corresponding size. Due to gravity, the steel foot support plate always remains in a downward position. The helical gear reducer motor drives the sprocket to rotate through the worm gear reducer, thereby driving the chain and the ball-head steel foot to move. When the ball-head steel foot passes above the moving paint-coating component, it follows the chain down and, after completing the paint coating, rises again, passing through the hot air circulation component and the adsorption component in sequence to complete the drying and toxic gas adsorption. Finally, it reaches the loading and unloading port, the closing component opens, and the unloading is completed.

[0013] The mobile paint-applying assembly includes a paint tank base frame and a paint pump. The lower four corners of the paint tank base frame are fixed with casters, and the upper end of the paint tank base frame is provided with two symmetrically arranged screw jack housings. The upper end of each of the two screw jack housings is equipped with a vertical screw, and the upper end of the two screws is fixed with a paint tank. The paint pump is located at the upper end of the paint tank base frame, and the input end of the paint pump is connected to an external paint storage tank, while the output end of the paint pump is connected to the paint tank.

[0014] With the above structure, the casters allow the entire mobile paint-dipping assembly to move flexibly. During equipment installation, debugging, or when the working position needs to be changed, the staff can easily push the mobile paint-dipping assembly to a suitable position to prepare for subsequent work. The paint pump can extract the paint from the paint tank and deliver it to the paint tank, ensuring that there is enough paint in the paint tank for the paint-dipping operation. The screw jack housing drives the connected screw to move up and down linearly through the internal transmission structure, synchronously driving the paint tank to rise or fall. The height of the paint tank can be precisely adjusted according to the actual position of the ball joint steel foot and the paint-dipping process requirements, so that the ball joint steel foot can be accurately immersed in the paint, ensuring a uniform and good paint-dipping effect.

[0015] The hot air circulation assembly includes a heating box, an air outlet plate, an air collection pipe, and a fan. The heating box and the fan are both fixed on the rear side of the frame. The air inlet of the heating box is connected to the air outlet of the fan. The air outlet plate is hollow inside and has several evenly distributed air outlets at its upper end. The air outlet plate is located on the upper end of the U-shaped side wall below the U-shaped partition. The air outlet of the heating box is connected to the air inlet of the air outlet plate. One end of the air collection pipe is located above the horizontal partition and is connected to the inside of the frame. The other end of the air collection pipe is connected to the air inlet of the fan. The air outlet of the fan is connected to the air inlet of the flat air outlet pipe through a pipe and a multi-port connector.

[0016] With the above structure, when the fan starts, it draws air from inside the frame through the air collection pipe and into the heating box. The heating box heats the air, turning it into hot air. The heated hot air is then output from the heating box, enters the air outlet plate, and is evenly blown out through the air outlet to dry the ball joint steel foot. During the drying process, some of the hot air flows inside the frame and is drawn back into the heating box through the air collection pipe. This cycle continues, achieving efficient utilization of the hot air and ensuring the drying effect of the ball joint steel foot.

[0017] The adsorption assembly includes a second fan, an activated carbon environmentally friendly adsorption box, and two exhaust hoods. The activated carbon environmentally friendly adsorption box is located on one side of the frame. The second fan is fixed on the side of the activated carbon environmentally friendly adsorption box, and the air inlet of the second fan is connected to the air outlet of the activated carbon environmentally friendly adsorption box. The two exhaust hoods are fixed on the rear side of the frame and located above the U-shaped partition. The air inlet of both exhaust hoods is connected to the inside of the frame, and the air outlet of both exhaust hoods is connected to the air inlet of the activated carbon environmentally friendly adsorption box. The air outlet of the second fan is connected to the air inlet of the flat air outlet pipe through a pipe and a multi-port connector.

[0018] With the above structure, when the second fan is running, the air containing paint mist and harmful gases inside the frame is drawn into the exhaust hood under its suction. The collected air containing paint mist and harmful gases enters the activated carbon environmental adsorption box. The activated carbon inside the activated carbon environmental adsorption box can effectively adsorb the paint mist and harmful components in the gas, purifying the air. The air purified by the activated carbon environmental adsorption box is discharged from the second fan into the outside environment, completing the entire adsorption and purification process. Then, the purified air is delivered to the flat air outlet pipe through the outlet end of the second fan via pipes and multi-port connectors, forming an air curtain.

[0019] The closure assembly includes two symmetrical sliding doors, four pull ropes, and four protective covers. The two sliding doors are located on the upper and lower sides of the sealing beam, respectively. Vertical guide rods are fixed to the front and rear sides of the sliding doors near the sealing beam. Limit blocks are fixed on the frame at positions corresponding to the guide rods. The end of the guide rod away from the sealing beam passes through the corresponding limit block, and a spring is fitted on each guide rod. The two ends of the spring abut against the sliding door and the corresponding limit block, respectively. Two mounting holes are opened at the upper and lower ends of the left side of the frame. The two mounting holes are symmetrical front and back, and pulleys are rotatably installed inside each mounting hole. Four take-up and release rollers are rotatably installed on the right side of the sealing beam. The four take-up and release rollers are divided into two groups of two, front and back. The two take-up and release rollers in the same group are symmetrically arranged vertically and each is fitted with a gear. The corresponding two gears mesh with each other. The four pull ropes are divided into two groups of two, upper and lower. The two pull ropes at the top are connected by a spring. The two pull ropes are fixedly connected to the front and rear ends of the upper sliding door. The other ends of the two upper pull ropes are connected to the two upper take-up rollers on the same side after passing through the pulleys on the same side. The two lower pull ropes are fixedly connected to the front and rear ends of the lower sliding door. The other ends of the two lower pull ropes are connected to the two lower take-up rollers on the same side after passing through the pulleys on the same side. Universal motors are fixed at both ends of the right side of the sealing beam. The output shaft of the universal motor at the front end is connected to the rotating shaft of one of the take-up rollers in the set at the front end. The output shaft of the universal motor at the rear end is connected to the rotating shaft of one of the take-up rollers in the set at the rear end. The four protective covers are fixed to the four limit blocks. The guide rods and springs are located inside the corresponding protective covers.

[0020] With the above structure, when the general-purpose motor is started, its output shaft rotates, driving the take-up and release rollers connected to it to rotate. Since the gears on the two take-up and release rollers in the same group mesh with each other, the rotation of one take-up and release roller will drive the other to rotate in the opposite direction. When the take-up and release rollers rotate, they perform the take-up and release operation on the pull rope, thereby driving the sliding door to move. The spring sleeved on the guide rod plays a buffering role when the sliding door moves. When the general-purpose motor reverses, the take-up and release roller releases the pull rope, and the elastic force of the spring pushes the sliding door to reset. The protective cover is fixed on the limit block, protecting the guide rod and spring inside, preventing them from being affected by external factors, and ensuring the stable operation of the closing assembly.

[0021] Compared with existing technologies, the continuous coating equipment for the ball head steel feet of this suspension insulator has the following advantages:

[0022] 1. By cooperating with the chain conveyor assembly and the moving paint-dipping assembly, the ball-head steel foot is driven down and immersed in the paint liquid of the moving paint-dipping assembly, thereby achieving uniform paint dipping and ensuring that the surface of the ball-head steel foot can be fully covered with paint. At the same time, the height and thickness of paint dipping can be adjusted.

[0023] 2. By combining the frame and chain conveyor components with the hot air circulation components, hot air circulates inside the frame, improving drying efficiency and ensuring that all parts of the ball head steel foot are dried evenly, avoiding localized undried or insufficiently dried conditions.

[0024] 3. By combining the frame with the adsorption components, paint mist and harmful gases generated during equipment operation are adsorbed in a timely manner, preventing these pollutants from spreading into the working environment and ensuring the health of operators and the safety of the working environment.

[0025] 4. By combining the frame, closed components, and flat air outlet duct, hot air leakage can be prevented, the temperature and airflow inside the frame can be kept stable, the leakage of paint mist and harmful gases into the external environment can be reduced, and dust can be prevented from entering the equipment, thereby further improving the environmental performance and working efficiency of the equipment.

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0040] like Figures 1-12 As shown, the continuous coating equipment for the ball head steel foot of this suspension insulator includes a frame 1, a chain conveyor assembly 2, an adsorption assembly 5, a closing assembly 6, a flat air outlet pipe 30, two movable coating assemblies 3, and two hot air circulation assemblies 4. The chain conveyor assembly 2 is located inside the frame 1. Both movable coating assemblies 3 are located inside the frame 1 and below the chain conveyor assembly 2. Both hot air circulation assemblies 4 are located on the rear side of the frame 1. The adsorption assembly 5 is located behind the frame 1. The adsorption assembly 5 and the two hot air circulation assemblies 4 are all connected to the interior of the frame 1. The closing assembly 6 and the flat air outlet pipe 30 are both located on the left side of the frame 1. The flat air outlet pipe 30 is located above the closing assembly 6 and is connected to the adsorption assembly 5.

[0041] In this embodiment, the ball-head steel foot is placed on the chain conveyor assembly 2, which transports it orderly to the top of the moving paint-dipping assembly 3. The moving paint-dipping assembly 3 contains paint liquid. Driven by the chain conveyor assembly 2, the ball-head steel foot descends and is immersed in the paint liquid in the moving paint-dipping assembly 3, thus achieving uniform paint coating and ensuring that the surface of the ball-head steel foot is fully covered with paint. After coating, the ball-head steel foot continues to move forward under the action of the chain conveyor assembly 2, entering the hot air circulation drying stage. The two hot air circulation assemblies 4 then begin operation. Hot air is generated by an internal heating device and transported to the inside of frame 1 through a pipe. The hot air circulates inside frame 1 and returns to the hot air circulation component 4. The adsorption component 5 can adsorb paint mist and harmful gases generated during equipment operation in a timely manner, preventing these pollutants from spreading into the working environment. The closing component 6 plays a protective role by sealing the opening on the left side of frame 1 to prevent hot air leakage and maintain stable temperature and airflow inside frame 1. The flat air outlet duct 30 blows an air curtain downward when the closing component 6 is opened to prevent dust from entering the inside of frame 1.

[0042] The frame 1 is a rectangular box with two front doors 7 at the front end. The positions of the two movable paint-applying components 3 correspond to the two front doors 7 respectively. The front doors 7 have observation ports 8, and transparent acrylic plates are fixed inside the observation ports 8. The upper part of the left side of the frame 1 has loading and unloading ports 9. A sealing beam 33 is fixed in the middle of the loading and unloading ports 9. The position of the closing component 6 corresponds to the loading and unloading ports 9. A U-shaped partition 10 and a horizontal partition 11 are fixed inside the upper part of the frame 1. The U-shaped opening of the U-shaped partition 10 faces to the right. The horizontal partition 11 is located between the two U-shaped side walls of the U-shaped partition 10. The U-shaped partition 10 and the horizontal partition 11 divide the space inside the upper part of the frame 1 into a drying channel.

[0043] In this embodiment, the front door 7 can be opened to facilitate routine maintenance and repair by staff. The observation port 8 allows staff to observe the internal condition of the equipment. The loading and unloading ports 9 are used for loading and unloading materials. The U-shaped partition 10 and the horizontal partition 11 divide the upper internal space of the frame 1 into a U-shaped space, which improves the space utilization rate, optimizes the flow path of hot air, and ensures that the hot air is in full contact with the ball head steel feet.

[0044] The chain conveyor assembly 2 includes two chains 12 symmetrically arranged front and rear. Two sprockets 13 are rotatably installed at each corner of the drying channel at the upper end of the frame 1 and above the movable paint-applying assembly 3. The corresponding two sprockets 13 are symmetrically arranged front and rear. One chain 12 is engaged with several sprockets 13 located in front, and the other chain 12 is engaged with several sprockets 13 located behind. Two worm gear reducers 15 are fixed on the front and rear sides of the frame 1. The positions of the worm gear reducers 15 correspond to the positions of two sprockets 13 on the same side, and the output shafts of the worm gear reducers 15 are respectively connected to... The sprocket 13 at the corresponding position is connected to the rotating shaft of the frame 1. Two helical gear reducers 14 are fixed on the front and rear sides of the frame 1. The output shafts of the two helical gear reducers 14 are respectively connected to the input shafts of two worm gear reducers 15 on the same side. Several crossbars 16 are evenly distributed and fixed between the two chains 12. Each of the crossbars 16 is rotatably provided with an L-shaped steel foot support plate 17. The upper end of the vertical part of the L-shape of the steel foot support plate 17 is sleeved on the corresponding crossbar 16. The horizontal part of the L-shape of the steel foot support plate 17 faces to the left, and several openings of different sizes are opened at the left end of the horizontal part of the L-shape of the steel foot support plate 17.

[0045] In this embodiment, the chain 12 is fitted onto the corresponding sprocket 13, and the ball-head steel foot is placed in the opening of the corresponding size. Due to gravity, the steel foot support plate 17 always remains in a downward state. The helical gear reducer motor 14 drives the sprocket 13 to rotate through the worm gear reducer 15, thereby driving the chain 12 and the ball-head steel foot to move. When the ball-head steel foot passes above the moving paint-coating component 3, it follows the chain 12 down and, after completing the paint coating, rises again, passing through the hot air circulation component 4 and the adsorption component 5 in sequence to complete the drying and toxic gas adsorption. Finally, it reaches the loading and unloading port 9, and the closing component 6 opens to complete the unloading.

[0046] The mobile paint application assembly 3 includes a paint tank base frame 18 and a paint pump 20. The lower end of the paint tank base frame 18 is fixed with casters 19 at all four corners. The upper end of the paint tank base frame 18 is provided with two symmetrically arranged screw jack housings 21. The upper end of each screw jack housing 21 is provided with a vertical screw 22. The upper end of the two screw jack housings 22 is fixed with a paint tank 23. The paint pump 20 is located at the upper end of the paint tank base frame 18. The input end of the paint pump 20 is connected to an external paint storage tank, and the output end of the paint pump 20 is connected to the paint tank 23.

[0047] In this embodiment, the casters 19 enable the entire mobile paint-dipping assembly 3 to move flexibly. When the equipment is installed, debugged, or the working position needs to be changed, the staff can easily push the mobile paint-dipping assembly to a suitable position to prepare for subsequent work. The paint pump 20 can extract the paint liquid from the paint storage tank and deliver it to the paint tank 23 to ensure that there is enough paint liquid in the paint tank 23 for the paint-dipping operation. The screw jack housing 21 drives the connected screw 22 to move up and down linearly through the internal transmission structure, which synchronously drives the paint tank 23 to rise or fall. The height of the paint tank 23 can be precisely adjusted according to the actual position of the ball joint steel foot and the paint-dipping process requirements, so that the ball joint steel foot can be accurately immersed in the paint liquid, ensuring a uniform and good paint-dipping effect.

[0048] The hot air circulation assembly 4 includes a heating box 24, an air outlet plate 25, an air collection pipe 26, and a fan 27. The heating box 24 and the fan 27 are both fixed on the rear side of the frame 1. The air inlet of the heating box 24 is connected to the air outlet of the fan 27. The air outlet plate 25 is hollow inside and has several evenly distributed air outlets at the top. The air outlet plate 25 is located on the upper end of the U-shaped side wall below the U-shaped partition 10. The air outlet of the heating box 24 is connected to the air inlet of the air outlet plate 25. One end of the air collection pipe 26 is located above the horizontal partition 11 and is connected to the inside of the frame 1. The other end of the air collection pipe 26 is connected to the air inlet of the fan 27. The air outlet of the fan 27 is connected to the air inlet of the flat air outlet pipe 30 through a pipe and a multi-port connector.

[0049] In this embodiment, the fan 27 operates, drawing air from inside the frame 1 through the air collection pipe 26 and into the heating chamber 24. The heating chamber 24 heats the air, turning it into hot air. The heated hot air is then output from the heating chamber 24, enters the air outlet plate 25, and is evenly blown out through the air outlet to dry the ball joint steel foot. During the drying process, some of the hot air flows inside the frame 1, is drawn back into the fan 27 through the air collection pipe 26, and re-enters the heating chamber 24 for heating. This cycle repeats, achieving efficient utilization of the hot air and ensuring the drying effect of the ball joint steel foot.

[0050] The adsorption assembly 5 includes a second fan 29, an activated carbon environmental adsorption box 31, and two exhaust hoods 32. The activated carbon environmental adsorption box 31 is located on one side of the frame 1. The second fan 29 is fixed on the side of the activated carbon environmental adsorption box 31. The air inlet of the second fan 29 is connected to the air outlet of the activated carbon environmental adsorption box 31. The two exhaust hoods 32 are fixed on the rear side of the frame 1 and located above the U-shaped partition 10. The air inlet of both exhaust hoods 32 is connected to the inside of the frame 1, and the air outlet of both exhaust hoods 32 is connected to the air inlet of the activated carbon environmental adsorption box 31. The air outlet of the second fan 29 is connected to the air inlet of the flat air outlet pipe 30 through a pipe and a multi-port connector.

[0051] In this embodiment, when the second fan 29 is running, the air containing paint mist and harmful gases in the frame 1 is drawn into the exhaust hood 32 under its suction. The collected air containing paint mist and harmful gases enters the activated carbon environmental adsorption box 31. The activated carbon inside the activated carbon environmental adsorption box 31 can effectively adsorb the paint mist and harmful components in the gas and purify the air. The air purified by the activated carbon environmental adsorption box 31 is discharged from the second fan 29 into the external environment, completing the entire adsorption and purification process. Then, the purified air is transported to the flat air outlet pipe 30 through the outlet end of the second fan 29 via pipes and multi-port connectors to form an air curtain.

[0052] The closing assembly 6 includes two symmetrical sliding doors 34, four pull ropes 38, and four protective covers 28. The two sliding doors 34 are located on the upper and lower sides of the sealing beam 33, respectively. Vertical guide rods 35 are fixed to the front and rear sides of the sliding door 34 near the sealing beam 33. Limiting blocks 36 are fixed on the frame 1 at positions corresponding to the guide rods 35. The end of the guide rod 35 away from the sealing beam 33 passes through the corresponding limiting block 36, and a spring 37 is sleeved on each guide rod 35. The two ends of the spring 37 abut against each other. On the sliding door 34 and the corresponding limiting block 36, two mounting holes are provided at both the upper and lower ends of the left side of the frame 1. The two mounting holes are symmetrical front and back, and each mounting hole is equipped with a pulley 39. Four take-up and release rollers 40 are rotatably provided on the right side of the sealing beam 33. The four take-up and release rollers 40 are divided into two groups of two, front and back. The two take-up and release rollers 40 in the same group are symmetrically arranged vertically and each is fitted with a gear 41. The two corresponding gears 41 mesh with each other. The four pull ropes 38 are divided into two groups of two, upper and lower. The two pull ropes located at the top are... One end of each rope 38 is fixedly connected to the front and rear ends of the upper sliding door 34. The other ends of the two upper pull ropes 38 are connected to the two upper take-up rollers 40 on the same side after passing through the pulleys 39 on the same side. One end of each of the two lower pull ropes 38 is fixedly connected to the front and rear ends of the lower sliding door 34. The other ends of each of the two lower pull ropes 38 are connected to the two lower take-up rollers 40 on the same side after passing through the pulleys 39 on the same side. Both ends of the right side of the sealing beam 33 are fixed with a universal motor 42. The output shaft of the universal motor 42 at the front end is connected to the rotating shaft of one of the take-up rollers 40 in the set at the front end. The output shaft of the universal motor 42 at the rear end is connected to the rotating shaft of one of the take-up rollers 40 in the set at the rear end. The four protective covers 28 are fixed to the four limit blocks 36. The guide rod 35 and the spring 37 are located inside the corresponding protective cover 28.

[0053] In this embodiment, the general-purpose motor 42 is started, and its output shaft rotates, driving the take-up and release roller 40 connected to it to rotate. Since the gears 41 on the two take-up and release rollers 40 in the same group mesh with each other, the rotation of one take-up and release roller 40 will drive the other to rotate in the opposite direction. When the take-up and release roller 40 rotates, it performs the take-up and release operation on the pull rope 38, thereby driving the sliding door 34 to move. The spring 37 sleeved on the guide rod 35 plays a buffering role when the sliding door 34 moves. When the general-purpose motor 42 reverses, the take-up and release roller 40 releases the pull rope 38, and the elastic force of the spring 37 pushes the sliding door 34 to reset. The protective cover 28 is fixed on the limit block 36, protecting the guide rod 35 and the spring 37 inside, preventing them from being affected by external factors, and ensuring the stable operation of the closing assembly.

[0054] The working principle of this utility model is as follows: Before the equipment is started, the operator places the ball-head steel feet to be painted on the steel foot support plate 17 of the chain conveyor assembly 2. In the chain conveyor assembly 2, the helical gear reducer motor 14 outputs power, which is reduced and increased in torque by the worm gear reducer 15, driving the sprocket 13 to rotate, and then driving the chain 12 to rotate in a cycle. The crossbar 16 is connected to the chain 12, and the steel foot support plate 17 moves accordingly. The openings of different sizes on the left end of the steel foot support plate 17 can accommodate ball-head steel feet of various specifications. After the material is loaded, the closing assembly 6 is started, and the universal motor 42 drives the take-up and release roller 40 to rotate. Through the cooperation of the pull rope 38 and the pulley 39, the two sliding doors 34 overcome the elastic force of the spring 37 and move along the guide rod 35 to close the loading and unloading ports 9. The spring 37 plays a buffering and reset role, and the protective cover 28 protects the guide rod 35 and the spring 37 from external interference, ensuring that the inside of the frame 1 is sealed. At the same time as the closing assembly 6 is opened, the flat air outlet pipe 30 blows out an air curtain to prevent dust from entering.

[0055] The ball-head steel foot moves with the chain conveyor assembly 2 to the top of the mobile paint-dipping assembly 3, and descends with the chain 12. The paint pump 20 of the mobile paint-dipping assembly 3 draws paint liquid from the external paint storage tank and injects it into the paint tank 23. The casters 19 at the bottom of the paint tank base frame 18 facilitate the adjustment of the equipment position. The screw jack housing 21 drives the screw 22, which can precisely adjust the height of the paint tank 23 so that the ball-head steel foot can be smoothly immersed in the paint liquid to complete the paint dipping. The thickness of the paint dipping can be adjusted according to the number of dippings.

[0056] After being coated with paint, the ball-shaped steel foot continues to move forward into the drying stage. The hot air circulation component 4 starts to work, the fan 27 runs, and the air inside the frame 1 is drawn in through the air collection pipe 26 and heated into hot air in the heating box 24. The hot air dries the ball-shaped steel foot through the air outlet of the air outlet plate 25. The U-shaped baffle 10 and the horizontal baffle 11 optimize the hot air path, so that it circulates within the frame 1, improving the drying efficiency.

[0057] During equipment operation, the adsorption component 5 works synchronously, the second fan 29 operates, and the air containing paint mist and harmful gases in the frame 1 is collected by the exhaust hood 32 above the U-shaped partition 10 and enters the activated carbon environmental adsorption box 31 for purification. The purified air is blown out by the second fan 29 through the flat air outlet pipe 30 to ensure a safe working environment.

[0058] After the ball-head steel foot completes the painting and drying process, the operator starts the universal motor 42 of the closing component 6 to reverse, the take-up roller 40 releases the pull rope 38, the spring 37 pushes the sliding door 34 to reset, the loading and unloading port 9 is opened, the finished product is taken out, and the ball-head steel foot to be painted is placed on the previous steel foot support plate 17. Then the loading and unloading port 9 is closed again to start a new round of operation. At the same time as the closing component 6 opens, the flat air outlet 30 blows out an air curtain to prevent dust from entering. The observation port 8 on the front door 7 is equipped with a transparent acrylic plate, so the operator can observe the internal situation at any time to ensure the stable operation of the equipment. The entire equipment achieves efficient, continuous and environmentally friendly painting operation of the ball-head steel foot of the suspension insulator through the close cooperation of various components.

[0059] In summary, by cooperating with the chain conveyor assembly 2 and the moving paint-dipping assembly 3, the ball-head steel foot is driven to descend and immersed in the paint liquid of the moving paint-dipping assembly 3, thereby achieving uniform paint dipping and ensuring that the surface of the ball-head steel foot can be fully covered with the paint layer. At the same time, the height and thickness of the paint dipping can be adjusted.

[0060] By combining the frame 1, the chain conveyor assembly 2 and the hot air circulation assembly 4, hot air circulates inside the frame 1, improving drying efficiency and ensuring that all parts of the ball head steel foot are dried evenly, avoiding localized undried or insufficiently dried conditions.

[0061] By combining frame 1 with adsorption component 5, paint mist and harmful gases generated during equipment operation are adsorbed in a timely manner, preventing these pollutants from spreading into the working environment and ensuring the health of operators and the safety of the working environment.

[0062] By using the frame 1, the closed component 6, and the flat air outlet duct 30 together, hot air leakage can be prevented, the temperature and airflow inside the frame 1 can be kept stable, the leakage of paint mist and harmful gases to the external environment can be reduced, and dust can be prevented from entering the equipment, thereby further improving the environmental performance and working efficiency of the equipment.
