Description

Technical Field

[0001] The utility model relates to the technical field of resistor processing equipment, in particular to a coating spraying device for resistor alloy plates. Background Technique

[0002] Alloy resistors are high-performance resistors. By changing their own materials and structural characteristics, they have more precise, more stable, and temperature-constant performance to achieve more stringent environments. The materials of these resistors are mostly nickel-chromium, manganese-copper, constantan alloy, etc. In order for alloy resistors to adapt to more environments, we need to spray insulating paint on the outer surface of alloy resistors to prevent alloy resistors from being corroded and avoid inter-turn short circuits in the circuit, so as to achieve the purpose of protecting the circuit.

[0003] In the existing spraying of insulating paint on alloy resistors, the situation of uneven spraying often occurs. At the same time, when spraying the surface of the resistor, due to the single-side spray gun, coating overlap will occur during spraying, resulting in uneven thickness of the coating. The thickness of the coating will also cause differences in the performance of the resistor. If the resistor performance is different, it will affect the safety of the circuit. In order to avoid inter-turn short circuits, we need to set up a targeted resistor painting device.

[0004] According to the above technical problems, we need to design a painting device for alloy resistors that can spray evenly. Content of the Utility Model

[0005] In order to overcome the disadvantage of uneven thickness of the insulating coating, the technical problem of the utility model is: to provide a coating spraying device for alloy resistors that can spray evenly.

[0006] The technical implementation plan of the utility model is: a coating spraying device for resistor alloy plates, including a chassis placed on the ground. A surrounding plate is fixedly connected to the chassis. A conveyor belt is installed on the chassis. Thirteen loading platforms are evenly fixedly connected to the conveyor belt. A resistor is slidably connected to the loading platform. Symmetrical long cylinders are fixedly connected to one side of the chassis close to the resistor. An angular cover is fixedly connected to the telescopic rod of the long cylinder. A loading box is fixedly connected to the middle of the chassis. One side of the loading box away from the resistor is fixedly connected to a telescopic round tube, and the telescopic round tube communicates with the loading box. The angular cover is fixedly connected to a telescopic round tube on the side away from the resistor. A right-angle tube is rotatably connected to one side of the telescopic round tube close to the resistor, and the right-angle tube communicates with the telescopic round tube. An extension round tube is fixedly connected to one side of the right-angle tube close to the resistor, and the right-angle tube and the extension round tube communicate with each other. A cover plate is slidably connected to the right-angle tube, and a large motor is fixedly connected to the upper end of the cover plate. The output shaft of the large motor is fixedly connected to the right-angle tube.

[0007] More preferably, it further includes a blower, which is fixedly connected to the chassis. On the side of the blower away from the resistor, two connecting thin tubes are fixedly connected. The blower and the connecting thin tubes communicate with each other. On the side of the angular cover away from the resistor, a connecting rod is fixedly connected. On the side of the connecting rod away from the angular cover, a hollow column is fixedly connected. On the side of the hollow column away from the resistor, two connecting thin tubes are fixedly connected. The hollow column and the connecting thin tubes communicate with each other. Also, because the blower and the connecting thin tubes communicate with each other, the hollow column and the blower communicate with each other.

[0008] More preferably, in order to better air-dry the paint, a plurality of thin and dense small holes are evenly opened on the inner wall of the hollow column, and the height of the hollow column is greater than that of the resistor, which can air-dry the insulating coating faster.

[0009] More preferably, it further includes an air suction machine, which is fixedly connected to the chassis. On the side of the air suction machine away from the resistor, a telescopic square tube is fixedly connected. The telescopic square tube and the air suction machine communicate with each other. On the side of the telescopic square tube close to the resistor, an auxiliary tube is fixedly connected. On the side of the angular cover away from the resistor, an auxiliary tube is fixedly connected. The auxiliary tube and the telescopic square tube communicate with each other. On the side of the angular cover away from the resistor, a hollow ring is fixedly connected. The hollow ring and the auxiliary tube communicate with each other.

[0010] More preferably, the telescopic square tube is made of soft material so that it can move up and down together with the angular cover.

[0011] More preferably, it further includes a rectangular rod, which is fixedly connected to the side of the angular cover away from the resistor. On the side of the rectangular rod away from the angular cover, a fixed frame is fixedly connected. On the side of the fixed frame away from the angular cover, a rotary brush is slidably connected. On the side of the fixed frame away from the angular cover, a small motor is fixedly connected. A small gear is fixedly connected to the output shaft of the small motor. The small gear and the rotary brush mesh with each other.

[0012] Compared with the prior art, the present utility model has the following advantages: In order to ensure that the device can spray paint evenly, first, the resistor is completely covered by the angular cover, so as to ensure that when spraying paint on the resistor, it will not be affected by the outside of the angular cover. And in order to ensure the spraying effect, the extension round tubes are arranged in a pair front and back, and at the same time, the spraying method of the extension round tubes is set to be rotary, so as to ensure the uniformity of the spraying thickness. The thickness of the paint layer can ensure the heat dissipation effect of the resistor. At the same time, in order to ensure the smooth operation of the entire spraying component, we will also set the long cylinder longer. If the effect is not good, the long cylinder can also be set to be multi-stage, so as to ensure that the angular cover will not affect the operation of the conveyor belt.

[0013] After the angular cover is lowered once, we achieve the air-drying effect through the hollow column connected to the outside of the angular cover. After completing a painting, in order to quickly dry the paint on the surface of the resistor and operate the device more quickly, and at the same time to ensure the effect of blowing, we first set up multiple connected thin tubes between the hollow column and the fan to achieve a larger ventilation volume. At the same time, we set the fan larger, so that multiple suction devices can be set in the fan, and the power of the fan is also set larger, so that the coating on the surface of the resistor can be quickly dried to avoid untimely drying, causing paint dripping, and affecting the working efficiency of the resistor.

[0014] When spraying paint on resistors, waste will occur. In order to operate the paint spraying device more continuously, we use a circular hollow ring set on the top of the angular cover to absorb the paint mist sprayed on the outside of the resistor into the telescopic square tube, and finally absorb the collected paint into the inside of the suction machine for storage. Finally, we can also reuse the collected materials.

[0015] In order to ensure the continuous operation of the suction function, we set the material of the telescopic square tube to rubber, so that the telescopic square tube can rise and fall together with the angular cover, thus ensuring the extension and shortening of the telescopic square tube. At the same time, in order to ensure the suction effect, we set the inner diameter of the telescopic square tube to a square, so that the vacuum machine can absorb more gas.

[0016] When spraying paint on the surface of the resistor, we need to create fine lines on the surface of the resistor to increase the adhesion of the paint. Therefore, we integrate the polishing mechanism into this device. First, we have a number of fine hard bristles on the inside of our rotating brush, so that we can ensure that the resistor is polished while avoiding damage to the resistor. At the same time, the outer side of the rotating brush is set in a gear shape, so that the resistor can be better polished through a small motor and a small gear. The resistor can also be better polished by controlling the speed of the rotating brush. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1: A coating spraying device for a resistor alloy plate, as Figures 1 - 4As shown in the figure, it includes a chassis 1. The chassis 1 is placed on the ground. A surrounding plate 2 is fixedly connected to the chassis 1. A conveyor belt 3 is installed on the chassis 1. Thirteen loading platforms 4 are evenly fixedly connected to the conveyor belt 3. A resistor 5 is slidably connected to the loading platform 4. Symmetrical long cylinders 7 are fixedly connected to the left and right sides in the middle of the chassis 1. An angular cover 6 is fixedly connected to the telescopic rod of the long cylinder 7. A loading box 8 is fixedly connected to the middle of the chassis 1. The right side of the loading box 8 is fixedly connected to the lower end of a telescopic round tube 9. The telescopic round tube 9 communicates with the loading box 8. The top end of the angular cover 6 is fixedly connected to the telescopic round tube 9. The upper end of the telescopic round tube 9 is rotatably connected to a right-angle tube 10. The right-angle tube 10 communicates with the telescopic round tube 9. Extension round tubes 1001 are fixedly connected to the left and right sides at the lower end of the right-angle tube 10. The right-angle tube 10 communicates with the extension round tubes 1001. A cover plate 11 is slidably connected to the right-angle tube 10. A large motor 12 is fixedly connected to the upper end of the cover plate 11. The output shaft of the large motor 12 is fixedly connected to the lower end of the right-angle tube 10.

[0030] When people need to spray an insulating coating on the surface of the resistor 5, first, place this device on the ground, then place the resistor 5 on the loading platform 4, then start the conveyor belt 3, and let the conveyor belt 3 run for a certain distance and then stop for a period of time, and move in this cyclic manner. When the conveyor belt 3 drives the resistor 5 to move to a position flush with the angular cover 6, the conveyor belt 3 stops rotating, and control the cylinder to descend so that the angular cover 6 covers the resistor 5. At this time, the connected telescopic round tube 9 will also contract accordingly. When the angular cover 6 descends until the cover plate 11 comes into contact with the resistor 5, the cover plate 11 remains stationary. First, start the large motor 12 on the cover plate 11, and let the large motor 12 drive the right-angle tube 10 and the extension round tubes 1001 to rotate clockwise. At this time, the water pump in the loading box 8 on the chassis 1 also starts to operate, and transfers the insulating paint inside to the extension round tubes 1001, and follows the rotation of the extension round tubes 1001 to spray onto the resistor 5 together. After the spraying is completed, first stop the water pump in the loading box 8, then stop the large motor 12 on the cover plate 11, then control the long cylinder 7 to extend, driving parts such as the angular cover 6, the telescopic round tube 9, and the right-angle tube 10 to rise together. Finally, start the conveyor belt 3 to drive the next resistor 5 close to the angular cover 6 to complete the next cycle.

[0031] Embodiment 2: On the basis of Embodiment 1, as Figure 5 and Figure 6 shown, it further includes a blower 13. The blower 13 is fixedly connected to the rear side of the chassis 1. Two connecting thin tubes 14 are fixedly connected to the left end of the blower 13. The blower 13 communicates with the connecting thin tubes 14. A connecting rod 16 is fixedly connected to the rear side of the angular cover 6. A hollow column 15 is fixedly connected to the rear end of the connecting rod 16. Two connecting thin tubes 14 are fixedly connected to the lower left side of the hollow column 15. The hollow column 15 communicates with the connecting thin tubes 14. Also, because the blower 13 communicates with the connecting thin tubes 14, the hollow column 15 communicates with the blower 13.

[0032] During the up-and-down movement of the corner cover 6, the hollow column 15 connected to the corner cover 6 will also move synchronously. When the corner cover 6 covers the resistor 5, the hollow column 15 will also enclose a resistor 5. At this time, the blower 13 connected to the chassis 1 will be started, and the blower 13 will push the air flow to reach the hollow column 15 through the connecting thin tube 14, and then blow from the hollow column 15 to the surface of the resistor 5. When the hollow column 15 moves up and down, the connecting thin tube 14 will also extend and contract accordingly to ensure the connection effect. When the corner cover 6 rises, the blower 13 will also stop running, and at the same time, the hollow column 15 will also rise together.

[0033] As Figure 6 shown, in order to better air-dry the paint, a plurality of thin and dense small holes are evenly opened on the inner wall of the hollow column 15, and the height of the hollow column 15 is greater than that of the resistor 5, which can air-dry the insulating coating faster.

[0034] When the hollow column 15 covers the resistor 5, in order to ensure more uniform air-drying of the resistor 5, a plurality of small holes are evenly opened on the inner side of the hollow column 15, and the hollow column 15 is also longer than the resistor 5, which is also to ensure the air-drying effect.

[0035] As Figure 7 and Figure 8 shown, it also includes an air suction machine 17. The air suction machine 17 is fixedly connected to the rear side of the chassis 1. A telescopic square tube 18 is fixedly connected to the right side of the air suction machine 17. The telescopic square tube 18 communicates with the air suction machine 17. An auxiliary tube 19 is fixedly connected to the left end of the telescopic square tube 18. The top end of the corner cover 6 is fixedly connected to the auxiliary tube 19. The auxiliary tube 19 communicates with the telescopic square tube 18. A hollow ring 20 is fixedly connected to the upper end of the corner cover 6. The upper end of the hollow ring 20 communicates with the auxiliary tube 19.

[0036] When the corner cover 6 descends and covers the resistor 5, the connected telescopic square tube 18 will also contract accordingly. When starting to spray paint, in order to ensure the spraying effect and avoid paint waste, the air suction machine 17 will be started first, and through the hollow ring 20 connected to the corner cover 6, the gas inside the cover will be sucked out. The sucked gas will first pass through the auxiliary tube 19, then the telescopic square tube 18, and then the air suction machine 17, and finally all be collected in the collection device inside the air suction machine 17. When the spraying stops, the air suction machine 17 also stops operating and extends along with the rising of the corner cover 6.

[0037] As Figure 7 and Figure 8 shown, the telescopic square tube 18 is made of soft material so that it can move up and down together with the corner cover 6.

[0038] In order to follow the lifting of the corner cover 6, we set the material of the telescopic square tube 18 to be a rubber soft material, so as to ensure that the telescopic square tube 18 can extend and contract along with the lifting of the corner cover 6.

[0039] As Figure 9 and Figure 10 shown, it further includes a rectangular rod 21, the rectangular rod 21 is fixedly connected to the front side of the corner cover 6, a fixed frame 22 is fixedly connected to the front end of the rectangular rod 21, a rotary brush 23 is slidably connected to the bottom end of the fixed frame 22, a small motor 24 is fixedly connected to the left part of the front side of the fixed frame 22, a small gear 25 is fixedly connected to the lower output shaft of the small motor 24, and the small gear 25 meshes with the rotary brush 23.

[0040] During each lifting of the corner cover 6, the fixed frame 22 connected together by the rectangular rod 21 also follows the lifting. When the corner cover 6 descends, the small motor 24 connected to the fixed frame 22 also starts at the same time. At this time, the small gear 25 connected above also rotates clockwise together. At this time, the rotary brush 23 fixed to the lower end of the fixed frame 22 and meshing with the small gear 25 also rotates counterclockwise. When the fixed frame 22 descends, the rotary brush 23 contacts and starts to rub against the resistor 5, and fine scratches will be rubbed on the surface of the resistor 5, and the small motor 24 will not stop rotating until the entire device stops operating, and then the small motor 24 will stop rotating.

[0041] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
