The zinc-nickel alloy layer is electroplated on the surface of the metal, so that the metal has the effects of improving the wear resistance, the conductivity, the light reflection performance and the corrosion resistance of the metal, improving the appearance and the like. The plating solution closer to the surface of the object to be plated is now called a "cathode film" in which the concentration of metal ions is lower as the plating proceeds, and a layer of liquid film from the point where the concentration of metal ions is reduced by 1% to the surface of the object to be plated is called a "cathode film". Since the metal ions on the surface of the plated part are gradually reduced, hydrogen gas is gradually generated, and the generated hydrogen gas bubbles can block the electroplating, which affects the electroplating effect, and the thickness of the cathode film can be reduced by using methods such as stirring.

The prior art can add a rabbling mechanism at electroplating pool central authorities and improve electroplating effect generally, but the liquid of its stirring can present the vortex type flow direction, and the interior outer velocity of flow difference of electroplating bath central point puts promptly, and the vortex central velocity of flow is close and zero, and plated item just is in this position, is unfavorable for electroplating to this rabbling mechanism can only carry out the stirring of horizontal direction to the plating solution, and the exchange effect of upper and lower layer plating solution is relatively poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a zinc-nickel alloy plating solution agitating unit to it is relatively poor to solve among the prior art electroplating bath central position stirring effect, can not stir the plating solution of vertical direction and influence the problem of electroplating effect.

In order to achieve the above object, the utility model provides a following technical scheme: the electroplating bath device comprises an electroplating bath and a centrifugal chamber, wherein two sides of the bottom of the electroplating bath are respectively provided with a stirrer, the bottom of the electroplating bath is connected with the centrifugal chamber, a turbine blade is arranged in the centrifugal chamber, the water outlet end of the centrifugal chamber is connected with a circulating pipe, the circulating pipe is communicated with the upper part of the electroplating bath, the lower side of the electroplating bath is provided with a transmission box, a transmission mechanism is arranged in the transmission box, and the transmission mechanism is in transmission connection with the stirrer and the turbine blade.

Preferably, a filter box is connected in series on the circulating pipe.

Preferably, an ultrasonic generator is arranged in the electroplating tank.

Preferably, the stirrer comprises a stirring shaft and stirring blades, the transmission mechanism comprises a motor, and the motor is fixed with the transmission case.

Preferably, a first driving wheel is fixed on the stirring shaft in the transmission case, a pair of second driving wheels is fixed on the driving shaft of the motor, and the second driving wheels are in transmission connection with the first driving wheels through belts or chains.

Preferably, the end of the driving shaft of the motor is fixedly connected with the turbine blade.

The utility model has the advantages that:

the utility model discloses a setting of two agitators in both sides can make the liquid flow rate of plating solution central authorities comparatively even, and the plating solution of bottom can be inhaled by the centrifuge box to circulate to the plating solution upper strata, the effectual stirring of having carried out the vertical direction to the plating solution, thereby improved electroplating quality.
