Description

Technical Field

[0001] This invention relates to the field of spray painting equipment, and in particular to a spray painting equipment for electrical porcelain appliances. Background Technology

[0002] Electrical porcelain and electrical appliances refer to all kinds of power equipment and devices manufactured with electrical ceramics (electrical porcelain) as the core insulation and structural components. They are key basic equipment in power systems to achieve insulation, support, protection and isolation. The painting equipment for electrical porcelain and electrical appliances is a special coating equipment for spraying insulating paint, anti-pollution flashover paint and weather-resistant paint on the surface of products such as electrical porcelain insulators, bushings and supports. The core is to form a uniform, dense and highly insulating protective coating on the surface of the porcelain parts, so as to improve the pollution resistance, weather resistance and insulation performance.

[0003] In existing technologies, most painting equipment for electrical porcelain appliances uses clamps to hold both ends or one end of the appliance and then rotates it to spray paint during rotation. In actual production, if the surface of the produced electrical porcelain appliance has minor scratches, local glaze loss, or small bumps, it is necessary to temporarily spray repair paint to repair the local area and avoid affecting the overall appearance. In this case, starting a large painting equipment alone requires starting the entire conveyor chain, fan, water curtain, paint supply system, and curing oven. Moreover, large equipment often sprays the entire electrical porcelain appliance, resulting in paint waste. If the painting is done while other electrical porcelain appliances are being painted, it will occupy the main production line capacity and affect the efficiency of normal mass production.

[0004] Therefore, it is necessary to propose a painting device for electrical porcelain appliances to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a spray painting device for electrical porcelain and electrical appliances, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A painting device for electrical porcelain includes a base plate and a movable block slidably connected to one side of the base plate. The surface of the movable block is provided with a painting mechanism for painting electrical porcelain. A rotating column is rotatably connected to the upper surface of the base plate near the edge. A rotating plate is fixedly connected to the surface of the rotating column. An installation groove is opened on the surface of the rotating plate near the rotating column. Slider blocks are symmetrically slidably connected to the groove wall. A first motor is fixedly connected to one side of the rotating plate. A bidirectional lead screw is fixedly connected to the output end of the first motor. Both sliders are threadedly connected to the bidirectional lead screw. An adjusting column is fixedly connected to the surface of the slider. Circular holes are equidistantly spaced on the surface of the adjusting column. A rotating block is rotatably connected to the wall of each circular hole. A conical groove is formed on the surface of the rotating block. A fixed sleeve is fixedly connected to the surface of the rotating block away from the conical groove. A T-shaped column is fitted onto the inner wall of the fixed sleeve. A first spring is fitted onto one end of the T-shaped column away from the rotating block. The other end of the first spring is fixedly connected to the fixed sleeve. The first spring is sleeved on the outside of the fixed sleeve. A spiral groove and a first strip groove are formed on the outside of the T-shaped column. The first strip groove communicates with the spiral groove. A protrusion is slidably connected to the wall of the first strip groove. The protrusion is fixedly connected to the inner wall of the fixed sleeve. The T-shaped column has a groove on its end face away from the rotating block. An adjusting block is installed on the groove wall by a torsion spring. A limit post is installed on the surface of the adjusting block. The ends of the multiple limit posts away from the adjusting block are fixedly connected to the rotating plate.

[0007] Preferably, rectangular blocks are symmetrically fixedly connected to the ends of the plurality of limiting posts away from the rotating plate, and two of the rectangular blocks are installed in conjunction with the adjusting block.

[0008] Preferably, both end faces of the rotating column are provided with circular grooves, and a connecting spring is fixedly connected to the wall of the circular groove. A connecting column is fixedly connected to the other end of the connecting spring. A disc is fixedly connected to the end of the connecting column away from the connecting spring. Multiple fixing rods are fixedly connected to the surface of the disc near the base plate. Limiting plates are installed at the ends of the multiple fixing rods away from the disc. Both limiting plates are fixedly connected to the base plate.

[0009] Preferably, the initial state of the connecting spring is a stretched state.

[0010] Preferably, the circular groove wall has a second strip groove that is evenly distributed in a ring shape, and multiple second strip grooves are slidably connected to the connecting column.

[0011] Preferably, the limiting plate has an arc-shaped groove evenly distributed in a ring on the surface near the disc, and an arc-shaped block is installed on the groove wall.

[0012] Preferably, the arc-shaped groove wall has a first inclined groove, and the arc-shaped block surface has a second inclined groove.

[0013] Preferably, an annular block is rotatably connected to the end of the T-shaped column away from the rotating block, and the annular block is fixedly connected to the first spring.

[0014] Compared with the prior art, the present invention provides a spray painting device for electrical porcelain appliances, which has the following beneficial effects: This electrical porcelain painting device, through a rotating block, adjusting column, slider, bidirectional lead screw, first motor, protrusion, spiral groove, T-shaped column, first spring, and fixed sleeve, is designed to allow the first motor to drive the bidirectional lead screw to rotate, thereby adjusting the two sliders to move closer together, which in turn allows the two adjusting columns to move closer together. The conical groove on the surface of the rotating block can make tight contact with both ends of the electrical appliance for clamping and positioning. Then, the painting mechanism sprays paint, which can adapt to the surface repair of electrical porcelain appliances of different specifications. It does not require the separate operation of large equipment and does not occupy the main production line capacity. The protrusion and spiral groove cooperate to automatically adjust the rotation of the fixed sleeve and rotating block after clamping and positioning the electrical porcelain appliance. In other words, the clamped electrical porcelain appliance can be adjusted and rotated. In conjunction with the painting mechanism, it can achieve the repair of electrical porcelain appliances of different specifications with minor scratches, local glaze loss, or small-area bumps.

[0015] This paint spraying device for electric porcelain appliances utilizes the cooperation between the arc-shaped block and the arc-shaped groove to stabilize and limit the rotating plate after it is rotated and adjusted. This allows for angle adjustment between the electric porcelain appliance and the paint spraying mechanism, enabling it to adapt to different parts of the electric porcelain appliance surface for touch-up painting and ensuring the touch-up effect.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1 to 8 A painting device for electrical porcelain includes a base plate 1 and a movable block 11 slidably connected to one side of the base plate 1. The surface of the movable block 11 is provided with a painting mechanism 12 for painting electrical porcelain. A rotating column 2 is rotatably connected to the upper surface of the base plate 1 near the edge. A rotating plate 3 is fixedly connected to the surface of the rotating column 2. An installation groove 4 is opened on the side of the rotating plate 3 near the rotating column 2. Slider 5 is symmetrically slidably connected to the groove wall of the installation groove 4. A first motor 6 is fixedly connected to one side of the rotating plate 3. A bidirectional lead screw 7 is fixedly connected to the output end of the first motor 6. Both sliders 5 are threadedly connected to the bidirectional lead screw 7. An adjusting column 8 is fixedly connected to the surface of the slider 5. Circular holes 9 are equidistantly opened on the surface of the adjusting column 8. A rotating block 10 is rotatably connected to the wall of the circular holes 9. A conical groove 101 is opened on the surface of the rotating block 10. A fixed sleeve 102 is fixedly connected to the surface of the rotating block 10 away from the conical groove 101. A T-shaped column 103 is fitted onto the inner wall of the fixed sleeve 102. A first spring is fitted onto one end of the T-shaped column 103 away from the rotating block 10. The other end of the first spring is fixedly connected to the fixed sleeve 102. The first spring is sleeved on the outside of the fixed sleeve 102. A spiral groove 104 and a first strip groove 105 are opened on the outside of the T-shaped column 103. The first strip groove 105 is connected to the spiral groove 104. A protrusion 106 is slidably connected to the wall of the first strip groove 105. The protrusion 106 is fixedly connected to the inner wall of the fixed sleeve 102. A groove 1031 is provided on the end face of the T-shaped column 103 away from the rotating block 10. An adjusting block 1032 is installed on the groove wall of the groove 1031 by a torsion spring. A limit post 1033 is installed on the surface of the adjusting block 1032. The ends of the multiple limit posts 1033 away from the adjusting block 1032 are all fixedly connected to the rotating plate 3.

[0020] Multiple limit posts 1033 are symmetrically fixedly connected to rectangular blocks 1034 at the ends away from the rotating plate 3, and both rectangular blocks 1034 are installed in conjunction with adjusting blocks 1032. It should be noted that an electric slide rail can be installed on the side of the base plate 1, and the movable block 11 is slidably connected to the electric slide rail. The painting mechanism 12 can adjust its position according to the condition of the clamped electric porcelain electrical appliance, and then perform touch-up painting. The painting mechanism 12 includes components such as connecting pipes, nozzles and delivery pumps, which are existing mature technologies and will not be described in detail here. A controller can be installed on the surface of the base plate 1 below the first motor 6. The electric slide rail, the first motor 6 and the painting mechanism 12 can all be electrically connected to the controller, which is controlled by a computer. It should be noted that during overall use, electric porcelain appliances with minor scratches, partial glaze loss, or small-area dents are placed between the two adjusting columns 8. Multiple appliances can be placed at once. The first motor 6 drives the bidirectional lead screw 7 to rotate, thereby adjusting the two sliders 5 to move closer to each other, that is, the two adjusting columns 8 to move closer to each other. The conical groove 101 on the surface of the rotating block 10 can make close contact with both ends of the electric porcelain appliance for clamping and positioning. Then, the painting mechanism 12 sprays paint, which can adapt to the surface repair of electric porcelain appliances of different specifications. Then, depending on the damaged parts of the actual electric porcelain appliance, the rotating plate 3 can be adjusted to rotate or not. If the rotating plate 3 is adjusted to rotate, the rotating column 2 rotates with the rotating plate 3. The arc block 262 cooperates with the arc groove 261 to limit the angle of the rotating plate 3. During the rotation of the first motor 6 driving the bidirectional lead screw 7, the two sliders 5 move towards each other, the adjusting column 8 moves with the sliders 5, and the rotating block 10 and the fixed sleeve 102 move with the adjusting column 8. Since the adjusting block 1032 is installed with the T-shaped rod through a torsion spring, initially, the T-shaped column 103 can move relative to the fixed sleeve 102, the protrusion 106 moves relative to the first slot 105, and then moves relative to the spiral slot 104. The fixed sleeve 102 and the rotating block 10 are adjusted and rotated. Due to the limiting effect of the rectangular block 1034 on the adjusting block 1032, the T-shaped column 103 will not rotate with the rotation of the fixed sleeve 102. The first spring is stretched, and the reaction force generated by the stretching of the first spring gradually increases. The adjusting block 1032 can gradually overcome the elastic force of the torsion spring as the first spring is stretched. The rectangular block 1034 and the adjusting block 1032 are adjusted and rotated. Separation, that is, after the electric porcelain appliance is clamped and positioned, the T-shaped column 103 can return to its initial state under the elastic force of the first spring. Since the adjusting block 1032 is restricted by the recess provided on the surface of the limiting column 1033, the T-shaped column 103 will not be adjusted and rotated. The fixed sleeve 102 and the rotating block 10 will also be adjusted and rotated due to the relative movement between the protrusion 106 and the spiral groove 104, thereby adjusting the rotation of the electric porcelain appliance. The painting mechanism 12 will then perform touch-up painting. There is no need to start large equipment separately, nor will it occupy the main production capacity. The protrusion 106 and the spiral groove 104 cooperate to automatically adjust the rotation of the fixed sleeve 102 and the rotating block 10 after the electric porcelain appliance is clamped and positioned. That is, the clamped electric porcelain appliance can be adjusted and rotated. With the help of the painting mechanism 12, it is possible to touch up the electric porcelain appliances of different specifications with slight scratches, local glaze loss, or small area bumps. It should be noted that casters can be symmetrically installed on the lower surface of the base plate 1, which enables the whole unit to move and is easy to use.

[0021] Both ends of the rotating column 2 are provided with circular grooves 21. A connecting spring 22 is fixedly connected to the groove wall of the circular groove 21. A connecting column 23 is fixedly connected to the other end of the connecting spring 22. A disc 24 is fixedly connected to the end of the connecting column 23 away from the connecting spring 22. Multiple fixing rods 25 are fixedly connected to the surface of the disc 24 near the base plate 1. Limiting discs 26 are installed at the ends of the multiple fixing rods 25 away from the disc 24. Both limiting discs 26 are fixedly connected to the base plate 1. The initial state of the connecting spring 22 is that it is stretched. It should be noted that the reaction force generated by the stretching of the connecting spring 22 acts on the surface of the connecting column 23, so that the arc block 262 and the arc groove 261 can be stably matched, thereby ensuring the stable state of the rotating plate 3 after angle adjustment.

[0022] The circular groove 21 has a second strip groove 211 evenly distributed in a ring on its groove wall, and multiple second strip grooves 211 are slidably connected to the connecting column 23; the limiting plate 26 has an arc groove 261 evenly distributed in a ring on its surface near the circular plate 24, and an arc block 262 is installed on the groove wall of the arc groove 261; the groove wall of the arc groove 261 has a first inclined groove, and the surface of the arc block 262 has a second inclined groove 263; It should be noted that during the process of adjusting the relative rotation between the rotating plate 3 and the base plate 1, the angle between the rotating plate 3 and the base plate 1 gradually increases. The rotating column 2 rotates together with the rotating plate 3. Since the connecting column 23 is slidably connected to the second strip groove 211, the rotation of the rotating column 2 can synchronously drive the connecting column 23 to rotate, which in turn can drive the disc 24 to rotate. The fixed rod 25 and the arc block 262 rotate with the disc 24. The arc block 262 and the arc groove 261 rotate relative to each other, and the first inclined groove and the second inclined groove 263 can rotate relative to each other. This does not restrict the rotation of the rotating plate 3. After the rotation adjustment is completed, under the action of the rotating plate 3's own gravity, the arc groove 261 and the arc block 262 are stably engaged, thereby restricting the rotation of the rotating plate 3 and preventing the rotating plate 3 from resetting, thus completing the angle adjustment of the electric porcelain appliance. It should be noted that, since the connecting column 23 is in contact with the wall of the circular groove 21, the friction between the two causes the arc block 262, the arc groove 261, and the limiting plate 26 to rotate relative to each other. During this process, the arc block 262, the fixing rod 25, and the circular plate 24 can be adjusted to move away from the limiting plate 26. Under the action of the connecting spring 22, they will not immediately return to their original positions. During the process of adjusting the rotating plate 3 to return to its original position, it is only necessary to adjust the angle between the rotating plate 3 and the base plate 1 to continue to increase, and then quickly adjust the rotating plate 3 to rotate in the opposite direction until it contacts the upper surface of the base plate 1. This facilitates the angle adjustment after clamping the electric porcelain electrical appliance.

[0023] A ring block 1035 is rotatably connected to the end of the T-shaped column 103 away from the rotating block 10, and the ring block 1035 is fixedly connected to the first spring. It should be noted that the setting of the annular block 1035 can ensure that during the adjustment and rotation of the fixed sleeve 102 and the rotating block 10, the annular block 1035 can rotate together with the fixed sleeve 102 without affecting the state of the first spring, thus ensuring the stable state of the first spring when it is adjusted and extended.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
