AI Technical Summary
During the copper foil production process, crystals are easily dropped from the gaps in the cathode roller end plates, resulting in poor sealing of the O-ring, anomalies such as copper plating and edge tearing, and affecting production efficiency and quality.
A 6mm diameter O-type sealing ring is used to fit tightly against the bolts on the cathode roller end plate, and water is supplied to the sealing ring through a drip unit for water sealing, ensuring that the gap is full and preventing crystals from entering the gap. The water sealing technology is combined to improve the sealing effect.
It effectively prevents the formation of crystallization pits, ensures the efficiency and quality of copper foil production, avoids copper plating and edge tearing abnormalities, and improves the sealing effect of the sealing ring.

[0006] Furthermore, the O-shaped sealing ring is arranged close to the bolts on the cathode roller end plate.
[0007] Furthermore, the diameter of the O-ring is 6 mm.
[0008] Furthermore, the dripping unit includes a pipe rack, a water pipe and a dripper. The pipe rack is fixed on the top of the frame, the water pipe is fixed on the pipe rack, the dripper is connected and fixed on the water pipe, and the dripping port of the dripper is set towards the O-ring.
[0009] Furthermore, the water pipe includes a straight pipe and an arc-shaped pipe, which are connected to each other. The straight pipe is fixed on the pipe rack and connected to the external water supply system. There are several drippers, which are evenly distributed on the arc-shaped pipe.
[0010] Compared with the prior art, the beneficial effects of the present invention are: this stage-speed air jet column machine with good jet effect has the following advantages: a 6mm O-ring surrounds the end plate gap on the cathode roller and rests against the bolts on the end plate, filling the end gap. During the operation of the cathode roller, the residual crystals inside the side cavity will not enter the end plate gap and produce crystal pressure pits. At the same time, it prevents the normal O-ring from sealing loosely, causing abnormalities such as copper plating and edge tearing, thereby ensuring the efficiency and quality of copper foil production.
