Problems solved by technology

Since the above processes are independent of each other and poorly correlated, a large amount of transfer time is brought in the process, resulting in a greatly extended coating treatment cycle.
[0005] In addition, before the coating, the staff is required to install the circuit, because the installation process will bring a certain amount of invalid time, which will further reduce the coating efficiency;
[0006] In addition, the electroplating solution needs to be cooled during the electroplating process to ensure the coating effect of the product. The traditional cooling method is to use an insulating sleeve to separate the electrolyte and the cooling liquid, and the heat transfer between the cooling liquid and the electrolyte is used to The electrolyte is cooled down, because the heat in the electrolyte cannot be recovered during the heat exchange process, so that the utilization rate of heat is low

Abstract

The invention discloses an aluminum profile surface coating device. An ultrasonic generator and a first heat exchange coil pipe are arranged in a left cleaning chamber. A water inlet and a water outlet of the first heat exchange coil pipe botch communicate with a circulating pump through a circulating pipeline. A lifting pump is arranged in a right cleaning chamber. The lifting pump communicates with a spray head through a pipeline. A drying box is arranged between a cleaning water tank and an oxidation tank. A heating pipe is arranged in the drying box. A drying mechanism is arranged on the drying box. The aluminum profile surface coating device further comprises an electric hoist. A wire rope of the electric hoist hoists an aluminum profile through a coating support. The electric hoist is driven by a drive mechanism to do a horizontal motion. The coating support is electrically connected with an electric control box through a clamp and an anode wire. The clamp can do a horizontal motion relative to an insulating sleeve. The aluminum profile surface coating device has the beneficial effects that the device is easy to operate, high in degree of automation and high in coating efficiency, and an oxidation film on the aluminum profile surface is resistant to wear and high in firmness.
