Plating tank closed cover switch mechanism

Abstract

The invention relates to a plating tank closed cover switch mechanism which comprises a tank body and a cover board, and is characterized in that the outer sides of two opposite tank walls of the tank body are respectively provided with a rotating shaft, a tank cover comprises two unit tank covers, two outer connecting rods and two inner connecting rods are arranged between the same ends of the two rotating shafts, one ends of the two outer connecting rods are respectively hinged between one ends of the two unit tank covers, the other ends of the two outer connecting rods are respectively hinged at the same ends of the two rotating shafts, one ends of the two inner connecting rods are respectively hinged at two ends of the inner edges of the two unit tank covers, the other ends of the two inner connecting rods are respectively hinged at the tank walls at the same ends of the two rotating shafts, the tank walls at two ends of the rotating shafts are respectively provided with an air cylinder, the piston rods of the air cylinders face upwards, lower connecting rods are respectively connected between the outer ends of the piston rods and the two inner connecting rods, the upper ends of the two lower connecting rods are respectively hinged between the two inner connecting rods, and the lower ends of the two lower connecting rods are hinged at the outer ends of the piston rods. By the plating tank closed cover switch mechanism disclosed by the invention, the tank opening and the tank cover are sealed, environmental pollution can be avoided, and the personnel healthy can be facilitated. The plating tank closed cover switch mechanism is suitable for plating tanks.

Description

[0001] The invention relates to a slot cover switch. Specifically, it is a tank cover opening and closing mechanism for electroplating the metal surface. Background technique [0002] It is known in the electroplating industry that for avoiding the distribution and overflow of harmful gas in the electroplating tank, the notch of the electroplating tank is equipped with a tank cover. The slot cover is an ordinary flat plate, which is realized by moving the slot cover horizontally when closing or opening. Owing to adopting the horizontal movement mode to realize the opening or closing of the slot cover, a sealing strip cannot be installed between the slot cover and the notch, which is difficult to seal, so that the gap between the slot cover and the notch is relatively large. In this way, during the electroplating process, the harmful gas in the tank will be emitted or overflow out of the tank, which not only pollutes the environment, but also endangers the health of operators....

AI Technical Summary

Problems solved by technology

Since the opening or closing of the slot cover is realized by horizontal movement, a sealing strip cannot be installed between the slot cover and the notch, and it is difficult to seal, resulting in a large gap between the slot cover and the slot

In this way, during the electroplating process, the harmful gas in the tank will be emitted or overflow out of the tank, which will not only pollute the environment, but also endanger the health of the operators.
