Method for adjusting water squeezing or acid squeezing through water or acid squeezing roller device for raw foil machine

Abstract

The invention provides a method for adjusting water squeezing or acid squeezing through a water or acid squeezing roller device for a raw foil machine. According to the method, the position of a sliding block is controlled through the cooperation of an adjusting screw rod with a spring and a reverse adjusting screw, the speed and precision of compression roller adjusting are improved, the pressing roller adjusting time is shortened by 50 percent, the rate of defective products is reduced by 50 percent in the process, the production cost is reduced, crush injuries caused by rigid stress on copper foil are avoided, when the thickness of the copper foil is changed, a fixed screw does not need to be adjusted, a water or acid squeezing roller automatically elastically compensates for marching or receding, operation is reduced, and meanwhile abnormal appearance quality problems such as chromatic aberration, a water channel, an acid channel and enlarging of the roughness difference caused by incomplete acid squeezing on the hair surface of the copper coil are solved.

Description

technical field [0001] The present invention relates to a method for regulating water squeeze or acid squeeze using a water squeeze or acid roll device for a raw foil machine. Background technique [0002] After the copper foil is turned out of the electrolyte of the electrolytic tank with the cathode roller, the electrolyte spray will be installed near the liquid surface of the electrolytic tank to remove the surface attachments. Squeeze out the acidic electrolyte, and then set water spraying at a position adjacent to the top of the acid squeeze roller to wash the rough surface of the copper foil. Above the water spray is a water squeeze roller to squeeze out the water on the surface. [0003] Existing water squeezing (acid) rollers fix the bearing housings on both sides of the cathode roller directly on the support. When the pressure roller is adjusted, press the water squeezing (acid) roller to the surface of the cathode roller. After pre-fixing, observe the water squeezi...

AI Technical Summary

Problems solved by technology

[0005] 1. The press roller and the cathode roller are rigidly pressed together. When the product thickness specification is changed, the press will be too loose or too tight. Every time the product thickness specification is changed, the screw must be adjusted to re-press, which increases the number of adjustments and time , it takes about 30 minutes for each adjustment, and about 30 meters of bad copper foil is produced during the process;

[0006] 2. During operation, the degree of pressure on the pressure rollers at both ends is only observed by personnel, which is prone to inconsistencies, appearance defects and troublesome adjustments, which can easily cause color differences, water channels, acid channels and roughness differences on the rough surface of copper foil. Major exception;

[0007] 3. When the pressing roller is completed and the screws are fixed, the cathode roller and the pressing roller surface are under rigid force. If there are hard objects such as copper sulfate crystals attached to the surface of the cathode roller or copper foil, the surface of the cathode roller may be seriously damaged.
