Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to an adjustable electrophoretic spraying device. Background Art

[0002] Electrophoretic spraying is a special painting process, mainly applied to the surface treatment of metal materials. The basic principle of this process is to place the object to be painted into a tank filled with electrophoretic paint. By applying an electric current in the tank, the resin and pigment particles in the paint become charged and move towards the opposite electrodes under the action of the electric field, and finally deposit on the metal surface to form a uniform coating. In the existing electrophoretic spraying device, when the workpiece is extended into the electrophoretic tank for electrophoretic spraying, due to the tiny unevenness on the surface of the workpiece, when the workpiece is immersed in the solution, bubbles will be formed. These bubbles may adhere to the surface of the workpiece and are not easy to escape. The paint cannot completely cover these bubbles, resulting in holes or defects in the coating, affecting the overall quality and protective performance of the coating, and causing uneven spraying. Therefore, the utility model proposes an adjustable electrophoretic spraying device. Summary of the Invention

[0026] like Figure 3 and Figure 4 As shown, the transmission assembly 5 includes a first sprocket 51 and a second sprocket 52 rotatably arranged on the bottom surface of the fixed plate 4, a motor 53 is arranged above the first sprocket 51, the motor 53 is fixedly installed on the upper surface of the fixed plate 4, and the output end of the motor 53 passes through the fixed plate 4 and is fixedly connected to the first sprocket 51, so as to drive the first sprocket 51 to rotate, a chain 54 is arranged between the first sprocket 51 and the second sprocket 52, so as to facilitate the cyclic transmission of the workpiece and the simultaneous spraying of multiple workpieces to improve the efficiency of spraying, a plurality of gears 55 are rotatably arranged on the bottom surface of the chain 54, a guide groove 56 is provided on the outer wall of the gear 55, the guide groove 56 is slidably connected to the guide block 9, and can guide and limit the gear 55, so that the movement of the gear 55 is more stable, a hook 57 is fixedly arranged on the bottom surface of the gear 55, so as to facilitate the simultaneous suspension of multiple workpieces for transmission, and improve the efficiency of spraying.

[0027] like Figure 1 As shown, an air dryer 11 is fixedly installed on one side of the electrophoresis box 1, and the air dryer 11 is composed of a motor, a fan blade, and a shell. It can quickly dry the solution sprayed on the surface of the workpiece to improve the spraying efficiency.

[0028] Furthermore, a fixing plate 12 is provided on the hook 57, and the fixing plate 12 is installed by a torsion spring, which can limit the suspended workpiece to prevent it from falling during the transmission process.
