Description

Technical Field

[0001] This utility model relates to the field of powder coating, and in particular to an electrophoretic powder coating device. Background Technology

[0002] In modern industrial production, coating processes have been widely used to improve the corrosion resistance, wear resistance, and decorative properties of metal products. Traditional coating methods, such as spray painting, have some drawbacks, such as low paint mist utilization and difficulty in ensuring coating uniformity. Electrophoretic coating, as a new type of coating technology, has advantages such as uniform coating, strong adhesion, and good environmental protection. It uses an external electric field to cause pigments and resin particles suspended in the electrophoretic solution to migrate directionally and deposit on the surface of the workpiece to form a coating.

[0003] However, the current electrophoretic coating and powder coating methods are difficult to combine. It is not possible to flexibly select two different equipment for electrophoresis and powder coating according to the product, or to combine the two equipment. It is difficult to obtain better coating results, which reduces the quality and service life of the workpiece. Therefore, we propose an electrophoretic powder coating device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an electrophoretic powder coating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electrophoretic powder coating device includes a liquid storage tank, a support base connected to the upper surface of the liquid storage tank, a rotator mounted on the upper surface of the support base, a rotating disk at the top of the rotator, and a ring of hooks mounted on the bottom surface of the rotating disk. A support plate is connected to the outer surface of the support base, a support cover is embedded in the bottom surface of the support plate, an electric cylinder is mounted on the inner bottom wall of the support cover, an electrophoretic liquid frame is mounted on the telescopic end of the electric cylinder, a powder-coated part is mounted on the upper surface of the liquid storage tank, a heat insulation cover is mounted on the outer surface of the electrophoretic liquid frame, and an electric heating wire is mounted on the inner wall of the heat insulation cover.

[0007] In a further embodiment, the powder-coated part includes a spraying pump mounted on the upper surface of a liquid storage tank. The input end of the spraying pump is connected to a liquid extraction pipe, the bottom end of which penetrates the liquid storage tank and extends into the interior of the tank. An injection hole is provided on the upper surface of the liquid storage tank. The output end of the spraying pump is connected to a drain pipe. Two sets of powder coating nozzles are connected to the outer surface of the drain pipe. A support block is connected to the outer surface of the drain pipe, and the bottom surface of the support block is connected to the upper surface of the liquid storage tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention, through the rotation device mounted on the support base, and in cooperation with the rotating disk and hook, can stably suspend the workpiece to be coated and achieve 360-degree rotation. This allows all parts of the workpiece to be treated evenly during powder coating and electrophoretic coating.

[0020] Please see Figures 1-4In this utility model, an electrophoretic powder coating device includes a storage tank 1, a support base 3 connected to the upper surface of the storage tank 1, a rotator 2 installed on the upper surface of the support base 3, a rotating disk 5 set at the top of the rotator 2, and hooks 6 arranged in a ring on the bottom surface of the rotating disk 5. A support plate 7 is connected to the outer surface of the support base 3, a support cover 8 is inlaid on the bottom surface of the support plate 7, an electric cylinder 10 is installed on the inner bottom wall of the support cover 8, an electrophoretic liquid frame 11 is installed at the telescopic end of the electric cylinder 10, a powder coating part 9 is installed on the upper surface of the storage tank 1, a heat insulation cover 12 is installed on the outer surface of the electrophoretic liquid frame 11, and an electric heating wire 13 is installed on the inner wall of the heat insulation cover 12. Through the cooperation of the heat insulation cover 12 and the electric heating wire 13, the electrophoretic liquid frame 11 can be heated to ensure its stability during electrophoretic treatment.

[0021] In a further embodiment, the powder-coated part 9 includes a spray pump 901 mounted on the upper surface of the liquid storage tank 1. The input end of the spray pump 901 is connected to a suction pipe 904. The bottom end of the suction pipe 904 penetrates the liquid storage tank 1 and extends into the interior of the liquid storage tank 1. An injection hole 14 is provided on the upper surface of the liquid storage tank 1. The output end of the spray pump 901 is connected to a drain pipe 902. Two sets of powder coating nozzles 903 are connected to the outer surface of the drain pipe 902. A support block 905 is connected to the outer surface of the drain pipe 902. The bottom surface of 05 is connected to the upper surface of the liquid storage tank 1. By starting the spray pump 901, the plastic powder coating can be drawn from the inside of the liquid storage tank 1 through the liquid extraction pipe 904. The spray pump 901 can transport the extracted coating through the drain pipe 902 to the two sets of powder coating nozzles 903 connected to it. The powder coating nozzles 903 spray the coating evenly on the surface of the rotating workpiece, thereby realizing the powder coating work. The support block 905 is set to fix the drain pipe 902 and ensure the stability of the drain pipe 902 during the spraying process.

[0022] In a further embodiment, the rotator 2 includes a servo motor 201 mounted on the upper surface of the support base 3. A drive shaft 204 is mounted on the output end of the servo motor 201. The top end of the drive shaft 204 is connected to the bottom surface of the rotating disk 5. A circular cover 202 is connected to the upper surface of the support base 3. A bearing ring 203 is embedded in the upper surface of the circular cover 202. The inner ring of the bearing ring 203 is connected to the outer surface of the drive shaft 204. By operating the servo motor 201, the drive shaft 204 and the rotating disk 5 can be driven to rotate, which can provide power for the rotation of the rotating disk 5. At the same time, the bearing ring 203 embedded in the upper surface of the circular cover 202 can reduce the friction when the drive shaft 204 rotates, ensuring smooth rotation.

[0023] In a further embodiment, a detection plate 15 is connected to the outer surface of the drain pipe 902, a first sensor 16 is installed on the upper surface of the detection plate 15, a detection support plate 17 is connected to the outer surface of the rotator 2, and a second sensor 4 is installed on one side of the detection support plate 17. Through the setting of the detection plate 15 and the first sensor 16, and in cooperation with the detection support plate 17 and the second sensor 4, the rotating workpiece can be sensed, and the sensed electrical signal will be transmitted to the external controller for analysis and processing. The external controller can control the operation of the corresponding powder-coated part 9, the rotator 2 and the electric cylinder 10.

[0024] The working principle of this utility model is as follows: The operator hangs the workpiece to be coated on the hook 6, then starts the rotator 2, which drives the rotating disk 5 to rotate, causing the workpiece hanging on the hook 6 to move in a circular motion around the central axis of the rotator 2, ensuring the subsequent coating process of the workpiece. Then, plastic powder coating is injected into the liquid storage tank 1 through the injection hole 14, and the powder coating 9 is started, which can evenly spray the coating onto the surface of the rotating workpiece. After the workpiece is powder coated, it is rotated to the top of the electrophoresis liquid frame 11. The electric cylinder 10 is then started to push the electrophoresis liquid frame. The rising of the 11 allows the workpiece to be positioned inside the electrophoretic liquid frame 11, enabling the pigments and resin particles in the electrophoretic liquid inside the frame 11 to migrate directionally and deposit on the workpiece surface to form a coating, thereby completing the electrophoretic powder coating of the workpiece. The heat insulation cover 12 installed on the outer surface of the electrophoretic liquid frame 11 covers the workpiece, and then the electric heating wire 13 on the inner wall of the heat insulation cover 12 is energized to heat and cure the plastic powder on the surface of the workpiece, so that the plastic powder forms a firm coating. The heat insulation cover 12 can reduce heat loss, improve heating efficiency, and protect the surrounding environment and equipment from high temperature.
