Technical Field
[0001] The invention relates to the field of insulator manufacturing, in particular to a spraying and drying device for glaze of a disc-shaped suspended porcelain insulator. Background Art
[0002] Insulators are devices installed between conductors of different potentials or between conductors and grounded components, and are able to withstand voltage and mechanical stress. Insulators come in many types and shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings. After the insulators are shaped by clay, insulating paint needs to be applied to the outside of the dried clay to increase insulation and structural strength.

After the spraying is completed, the uneven spraying of the glaze can be detected, and it is not easy to change. In addition, the insulator itself has an arc and a cone shape.

[0016] The present invention also discloses a spraying and drying process for a disc-shaped suspended porcelain insulator glaze, comprising the following steps:
[0017] The first step is to fix the insulator body in the placement slot, start the motor to rotate the insulator body, and judge whether the insulator body has defects by the amplitude of the vibration when the insulator body rotates;
[0018] Step 2: Push the spray box close to the insulator body through the first electric push rod, adjust the distance, and the pump body sucks the glaze, and sprays the glaze on the outside of the insulator body through the spray box;
[0019] Step 3: After spraying, use the camera to observe whether the glaze is sprayed evenly;
[0020] Step 4: After checking that the spraying is uniform, the glaze is preliminarily heated. After the preliminary heating is completed, the glaze is dried for a second time. If the spraying is detected to be uneven, the sprayed glaze is scraped off.
[0021] Technical effects and advantages of the present invention:
[0022] 1. In the present invention, while rotating and spraying glaze on the insulator body, it is possible to detect not only whether the glaze on the surface of the insulator body is uniform, but also whether the appearance of the insulator body is qualified, and whether the thickness of the glaze is uniform.
[0023] 2. In the actual operation of the present invention, in the initial state, the spray box is retracted inside the first embedded groove, so that the insulator body can be installed inside the placement groove without blocking the insulator body. When the insulator body is installed, the second electric push rod can be driven to drive the spray box to rotate and descend, and finally the inclination of the bottom end of the spray box and the outer side of the insulator body correspond, so that the spraying is more uniform and consistent.
[0024] 3. After the insulator body is installed, the two spraying slots can spray the outside and bottom of the insulator body at the same time. When the insulator body rotates one circle following the driving shaft of the motor, the task of spraying the entire insulator body can be completed, which saves time and effort. Compared with the spraying process of manual and robotic arm spray guns, the present invention sprays in accordance with the shape of the insulator body itself, and the spraying effect is more uniform.
[0025] 4. When the insulator body is rotating and spraying glaze, the vibration generated by the motor will be transmitted to the insulator body. The vibration amplitude is small, but the vibration process can help the glaze to be evenly distributed on the surface of the insulator, increase the uniformity of the glaze, and when the glaze is sprayed unevenly, the glaze will cause the center of gravity of the insulator body to shift and increase the vibration amplitude of the rotation. Since the glaze itself has fluidity, it can increase the motion state of the glaze molecules, improve the uniformity of the glaze, and make the center of gravity of the insulator body close to stability.
[0026] 5. In the actual operation of the present invention, after the glaze is sprayed, the second electric push rod can be retracted, so that the second electric push rod can pull the spray box back to the inside of the first embedded groove to complete the storage work, and at the same time it is convenient for personnel to take out the insulator body. Furthermore, when personnel observe through the camera that the glaze is sprayed unevenly, the first electric push rod can be controlled to extend, and the first electric push rod drives the scraper to extend, and the scraper is attached to the outside of the insulator body. When the insulator body is driven to rotate by the motor, the scraper can scrape off the glaze sprayed on the outside of the insulator body.
[0027] 6. Part of the scraped glaze will fall down, and the other part will stick to one side of the scraper. Therefore, when the scraper and the spray box retract into the first embedded groove, the side of the scraper that sticks to the glaze will contact the brush. The friction between them can remove the glaze from the scraper, making it easier to apply the next coat of paint.
[0028] 7. When the glaze is sprayed evenly, the hot air blower can be started after spraying. The hot air generated by the hot air blower can enter the inside of the placement slot through the nozzle and the hot air outlet to dry the glaze on the outside of the internal insulator body. At the same time, the hot air output from the discharge port on the triangular block can dry the bottom of the insulator body. At the same time, since the insulator body itself is in a rotating state, the drying speed can be accelerated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0036] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0037] The present invention provides Figure 1 - Figure 6 The spraying and drying device for the glaze of a disc-shaped suspended porcelain insulator shown in the figure comprises a base 1 and a spray box 2 arranged on the top of the base 1, a placement groove 3 is opened on the top of the spray box 2, a rotating disk 13 is rotatably connected to the bottom end of the placement groove 3, a fixing column 29 is fixed on the rotating disk 13, an insulator body 14 is placed on the rotating disk 13, the fixing column 29 is inserted into a through hole opened in the center of the insulator body 14, a temperature sensor is fixed on the inner wall of the spray box 2, and the temperature sensor can detect the temperature condition inside the spray box 2.
[0038] A vibration sensor 30 is embedded in the top of the rotating disk 13, a motor is fixed inside the base 1, the driving shaft of the motor is fixedly connected to the center of the bottom end of the rotating disk 13, a first embedded groove 5 is opened on one side of the placement groove 3, and a spraying mechanism 12 is arranged in the first embedded groove 5.
[0039] In the actual operation of the present invention, after the motor is started, it can drive the rotating disk 13 and the fixed insulator body 14 to rotate. The spraying mechanism 12 can face the insulator body 14 and perform spraying. The insulator body 14 rotates one circle through the rotating disk 13 to complete the task of spraying the outer side of the entire insulator body 14.
[0040] The insulator body 14 is similar to a cone, and the center of gravity is in the middle of the insulator body 14. If there are protrusions or depressions on the surface of the insulator body 14, resulting in an uneven center of gravity of the insulator body 14, a certain centrifugal effect will be generated when the insulator body 14 rotates, causing the insulator body 14 to shake. Whether the insulator body 14 is qualified can be judged by observing the shaking of the insulator body 14. Therefore, a vibration sensor 30 is provided. When the insulator body 14 shakes, the vibration signal will be transmitted to the vibration sensor 30. The vibration sensor 30 is used to detect whether the insulator body 14 has defects before spraying. At the same time, the vibration data detected by the vibration sensor 30 is more detailed and accurate than that detected by the human eye.
[0041] When the insulator body 14 rotates, it can be observed by naked eyes or by a camera 34 to see whether the glaze on the surface of the insulator body 14 is uniform. If it is not uniform and the color is inconsistent, it can be clearly observed whether the glaze is sprayed uniformly.
[0042] A camera 34 is embedded in the inner wall of the spray box 2. In the actual three-dimensional space, the movement of points, lines and surfaces eventually forms various three-dimensional shapes. Specifically, when an object rotates around its axis, every point on its surface is moving in a circle, and the movement trajectories of these points visually form a circular and uniform appearance.
[0043] Therefore, when the surface of the insulator body 14 is coated with glaze, the glaze points on its surface will form a ring pattern with uniform color when the insulator body 14 rotates. If the glaze is sprayed unevenly, different ring patterns will have different colors. Personnel can use the camera 34 to observe the color or shape of the glaze to determine whether the glaze on the surface of the insulator body 14 is uniform, and can also determine whether the glaze thickness is uniform.
[0044] Therefore, in the present invention, while rotating and spraying the glaze on the insulator body 14 , it is possible to detect not only whether the glaze on the surface of the insulator body 14 is uniform, but also whether the appearance and shape of the insulator body 14 is qualified.
[0045] In addition, the spraying mechanism 12 itself can adjust the angle to facilitate the spraying operation close to the insulator body 14.
[0046] Specifically, the spraying mechanism 12 includes a fixed plate 15, a spray box 17 and a bottom spray box 25. The fixed plate 15 is fixed to one side of the bottom end of the first embedded groove 5, one side of the spray box 17 is rotatably connected to the fixed plate 15, one end of the bottom spray box 25 is fixed to the inner wall of the placement groove 3, and one side of the fixed plate 15 close to the spray box 17 is rotatably connected to the rotating shaft 16. One side of the spray box 17 is fixed on the rotating shaft 16. The spray box 17 can be rotated by the rotating shaft 16 to adjust the tilt angle.
[0047] A spraying slot 26 is provided on the opposite side of the bottom spray box 25 and the spray box 17, a scraper 19 is telescopically provided on the opposite side of the spray box 17 and the bottom spray box 25, a hinge seat 24 is fixed on the inner wall of the first embedded groove 5 and the opposite side of the spray box 17, and a second electric push rod 21 is rotatably connected between the two hinge seats 24.
[0048] A first electric push rod 18 is embedded in the opposite side of the spray box 17 and the bottom spray box 25. One end of the two first electric push rods 18 extends out of the spray box 17 and the bottom spray box 25 respectively, and a scraper 19 is fixed to the two extended ends. An electric heating wire 20 is arranged inside the scraper 19. The length of the spray box 17 corresponds to the length of the hypotenuse of the insulator body 14. When the glaze is sprayed and the glaze is relatively uniform, the electric heating wire 20 can be started. Since the scraper 19 is close to the glaze at this time, the glaze can be preheated at a relatively close distance, which is convenient for increasing the speed of subsequent drying.
[0049] In the actual operation of the present invention, in the initial state, the spray box 17 is retracted inside the first embedded groove 5, so that the insulator body 14 can be installed inside the placement groove 3 without blocking the insulator body 14. When the insulator body 14 is installed, the second electric push rod 21 can be driven to drive the second electric push rod 21 to drive the spray box 17 to rotate and descend, and finally the inclination of the bottom end of the spray box 17 and the outer side of the insulator body 14 correspond, so that the spraying is more uniform and consistent.
[0050] A discharge port 10 is provided at the top of one side of the first embedded groove 5, and two pump bodies are arranged inside the spray box 2, one of which is connected to a hose 11, one end of the hose 11 extends out of the discharge port 10, and the extended end is communicated with the interior of the spray box 17, and the other pump body is connected to the interior of the bottom spray box 25 through a pipeline. Both pump bodies can be connected to the glaze through a suction pipe, and the pump body can pump the glaze to the corresponding spray box 17 and the bottom spray box 25, and spray it out from the spray slot 26 on the opposite side of the spray box 17 and the bottom spray box 25. When the insulator body 14 is installed, the two spray slots 26 can spray the outside and the bottom of the insulator body 14 at the same time. When the insulator body 14 rotates one circle following the driving shaft of the motor, the task of spraying the outside of the entire insulator body 14 can be completed, which saves time and effort. Compared with the spraying process of manual and mechanical arm spray guns, the present invention conforms to the shape of the insulator body 14 itself for spraying, and the spraying effect is more uniform.
[0051] When the insulator body 14 is rotating and spraying glaze, the vibration generated after the motor is started will be transmitted to the insulator body 14. The vibration amplitude is small, but the vibration process can help the glaze to be evenly distributed on the surface of the insulator, increase the uniformity of the glaze, and when the glaze is sprayed unevenly, the glaze will cause the center of gravity of the insulator body 14 to shift and increase the vibration amplitude of the rotation. Since the glaze itself has fluidity, it can increase the motion state of the glaze molecules, improve the uniformity of the glaze, and make the center of gravity of the insulator body 14 close to stability.
[0052] A silicone vertical plate 22 is provided on the side of the spray box 17 away from the fixed plate 15 , and the bottom end of the silicone vertical plate 22 is fixed to the bottom end of the first embedded groove 5 . A brush 23 is fixed on the side of the silicone vertical plate 22 close to the spray box 17 , and the brush 23 is attached to one side of the scraper 19 .
[0053] In the actual operation of the present invention, after the glaze is sprayed, the second electric push rod 21 can be retracted, so that the second electric push rod 21 pulls the spray box 17 back into the first embedded groove 5 to complete the storage work and facilitate personnel to take out the insulator body 14.
[0054] Furthermore, when personnel observe through the camera 34 that the glaze is unevenly sprayed, they can control the first electric push rod 18 to extend, and the first electric push rod 18 drives the scraper 19 to extend, and makes the scraper 19 fit the outside of the insulator body 14. When the insulator body 14 is driven by the motor to rotate, the scraper 19 can scrape off the glaze sprayed on the outside of the insulator body 14.
[0055] Part of the scraped glaze will fall down, and the other part of the glaze will adhere to one side of the scraper 19. Therefore, when the scraper 19 and the spray box 17 retract into the first embedded groove 5, the side of the scraper 19 that adheres to the glaze will contact the brush 23. The friction between them can remove the glaze from the scraper 19, which is convenient for the next coating. After the glaze is sprayed out through the spraying groove 26, it is blocked by the scraper 19, which can prevent the glaze from being scattered and sprayed to other places, so that the glaze can be accurately sprayed onto the insulator body 14. At the same time, scrapers 19 are provided on the upper and lower sides to spray the upper and lower surfaces of the insulator body 14 at the same time. At the same time, the spraying thickness can be adjusted by adjusting the distance between the scraper 19 and the surface of the insulator body 14.
[0056] A filter screen 9 is arranged on the outer side of the rotating disk 13, and the outer side of the filter screen 9 is fixed on the inner wall of the placement groove 3, and the filter screen 9 is arranged below the bottom spray box 25. A triangular block 27 is fixed on the filter screen 9, and a discharge port 28 is opened on the oblique side of the triangular block 27 near the bottom end of the insulator body 14, and a fence 8 is arranged on the outer side of the filter screen 9.
[0057] A second embedded groove 6 is opened on the other side of the placement groove 3, and a hot air outlet 7 is arranged in the second embedded groove 6. A hot air blower 31 is fixed to the outside of the spray box 2, and the air outlet of the hot air blower 31 is connected to the hot air outlet 7 and the exhaust port 28 respectively through a connecting pipe. A transparent cover plate 4 is hinged on one side of the top of the spray box 2, and a nozzle 33 is opened on the side of the transparent cover plate 4 close to the placement groove 3, and an air pipe 32 is connected between the hot air blower 31 and the nozzle 33.
[0058] In the actual operation of the present invention, during the spraying process, the transparent cover 4 is closed to shield the placement groove 3, so that the insulator body 14 is sprayed in a sealed environment, reducing the impact of dust and impurities in the air on the glaze, and the transparent cover 4 is made of transparent material, and personnel can also check the rotation and shaking of the internal insulator body 14 through the transparent cover 4 to detect whether the glaze is uniform; further, when the glaze is sprayed, and the uniformity is good, the hot air blower 31 can be started, and the hot air generated by the hot air blower 31 can enter the interior of the placement groove 3 through the nozzle 33 and the hot air outlet 7 to dry the glaze on the outside of the internal insulator body 14, and at the same time, the hot air output from the discharge port 28 on the triangular block 27 can dry the bottom end of the insulator body 14. At the same time, since the insulator body 14 itself is in a rotating state, the drying speed can be accelerated.
[0059] The present invention also discloses a spraying and drying process for a disc-shaped suspended porcelain insulator glaze, which is characterized by comprising the following steps:
[0060] S1. After fixing the insulator body 14 in the placement slot 3, the motor is started to rotate the insulator body 14. The amplitude of the shaking of the insulator body 14 during the rotation is used to determine whether the insulator body 14 has defects.
[0061] S2, push the spray box 17 close to the insulator body 14 through the first electric push rod 18, adjust the distance, the pump body sucks the glaze, and sprays the glaze on the outside of the insulator body 14 through the spray box 17;
[0062] S3, after spraying is completed, observe whether the glaze is sprayed evenly through the camera 34;
[0063] S4. After the spraying is detected to be uniform, the glaze is preliminarily heated. After the preliminarily heating is completed, the glaze is dried for a second time. If the spraying is detected to be uneven, the sprayed glaze is scraped off.
