Abstract

The invention relates to an automatic control system for the acid cleaning of a conductive roller of an aluminium foil production line, comprising a controller and an actuating mechanism, wherein the controller is a time schedule controller comprising a power source part, a timing part, a frequency demultiplication self-locking part and an output drive part, and the parts and components in the parts are respectively electrically connected with one another; and the actuating mechanism comprises an acid cleaning controller, a water discharge electrically operated valve, an acid discharge electrically operated valve, an acid cleaning electrically operated valve, a hand-operated acid cleaning control button and a magnetic pump which are electrically connected with one another. The system automatically controls the acid cleaning time, the acid cleaning period, the water discharge, the acid discharge and other programs, automatically and effectively cleans the conductive roller of the aluminium foil production line, leads the washing and the cleaning of the conductive roller to be simple and reliable, increases the supply current and the vehicle speed of the production line, improves the production efficiency and reduces the production cost. The system has the structure that an analog circuit is combined with a plurality of circuit chips, and the system has the characteristics of low cost, simple and reliable control, no need of software support, low cost of later maintenance, etc.

Description

technical field [0001] The invention relates to the production of aluminum foil, in particular to a control system for pickling conductive rollers on the aluminum foil production line. Background technique [0002] In the etching process of electronic aluminum foil, strong acid and low voltage and high current are generally used for etching. The connection medium between the power supply and the electronic aluminum foil is a copper roller or a silver roller (collectively referred to as a conductive roller), and its speed is proportional to the power supply current; to increase production capacity, the power supply current must be increased, and the increase in current is related to the cleanliness of the surface of the conductive roller ( Such as oxide film, aluminum powder, etc.) have a great relationship. There are two commonly used methods in the cleaning process of conductive rollers: one is to use abrasive materials to clean the conductive rollers based on the principl...

Problems solved by technology

There are two commonly used methods in the cleaning process of conductive rollers: one is to use abrasive materials to clean the conductive rollers based on the principle of contact relative motion. Long-term use of this method will cause serious damage to the conductive rollers and large fluctuations in the tension of the entire production line. and other defects; the other is to use the acid solution with hydrochloric acid in the production process for cleaning. This method will cause less damage to the conductive roller and will not cause large fluctuations in the tension of the entire production line, but it involves pickling time. , pickling cycle, drainage, acid discharge of various program control and conversion, the operation is complex and difficult
