The potassium chloride supplied into the opening and closing tube 84 is weighed in the load cell 83, and when the measured value of potassium chloride reaches the set weight, the polarity of the electromagnet 71 is formed opposite to the permanent magnet 55, and the shaft 52 ), The connecting gear 51 is stopped from the connecting clutch 46 to stop the rotation and the supply is also stopped.

On the other hand, the process in which the potassium chloride supplied in the appropriate amount into the opening and closing tube 84 is introduced into the solution production tank 4, when the two motors 86 rotate in opposite directions with respect to each other, both of the shafts 78 The gear 77 installed in engagement with the semi-circular rack gear 85 inside the opening and closing tube 84 is rotated to advance the semi-circular rack gear 85.

When the semi-circular rack gear 85 proceeds, the opening and closing pipes 84 on both sides of the shaft 75 move in opposite directions with respect to each other to open potassium chloride into the solution production tank 4.

At the same time, as the brush 76 inserted into the shaft 78 is rotated, the potassium chloride remaining on the inner surface of the opening and closing tube 84 is neatly introduced into the solution production tank 4.

This operation is repeated when the supply of potassium chloride in the solution preparation tank is required, so that an appropriate amount of potassium chloride can be added.

According to the potassium chloride input device of the electroplating process according to the present invention as described above, by preparing a solution of the appropriate amount of potassium chloride by grinding and powdering the solidified potassium agglomerated potassium chloride in the hopper and the solidified potassium chloride adhered to the bottom of the hopper It can be put into the tank.

Accordingly, it is possible to produce the best solution by optimizing the solution composition, and by performing the plating operation with such a solution, it is possible to produce an electroplating product having a beautiful surface and excellent plating quality.
