Pickling and phosphating automatic continuous production electrical control system

Abstract

The invention provides a pickling and phosphating automatic continuous production electrical control system which is composed of a master station and multiple slave stations. The master station is composed of a programmable controller PLC, a 5GHZ radio station I and a touch screen and arranged in a ground master control room. Each slave station is composed of a 5GHZ radio station II, a network adapter and an IO module and arranged on a line pickling trolley. The master station and the slave stations form a wireless ethernet of the star structure, wherein connection is realized through wireless signals and the programmable controller PLC acts as the core. When the line pickling trolley arrives at the working position, the sensor arranged on the line pickling trolley obtains the signals and wirelessly transmits the signals to the programmable controller PLC of the master station. The programmable controller PLC judges the working position of the line pickling trolley according to the received signals and transmits a corresponding instruction to the line pickling trolley to control operation of the line pickling trolley. The control system is simple in structure and accurate in control.

Description

technical field [0001] The invention relates to an electrical control system for automatic continuous production of pickling and phosphating, which belongs to the technical field of metal product production. Background technique [0002] The existing steel wire pickling and phosphating production line is backward in technology. Due to the small scale of production, the supporting workshop space is low and narrow. During the production, each steel wire is hung by the staff to wear the shaft bar type, and the operation is carried out by driving the hoisting type. The technical parameters of each station, the washing time and the frequency of changing the solution are judged by human experience. This kind of production method is relatively backward, and the indicators are not easy to control and solidify. It is not conducive to large-scale production and does not adapt to market development. need. [0003] Its disadvantages are as follows: 1. The long-term backward production...

AI Technical Summary

Problems solved by technology

The technical parameters of each station, the washing time and the frequency of changing the solution are judged by human experience. This kind of production method is relatively backward, and the indicators are not easy to control and solidify. It is not conducive to large-scale production and does not adapt to market development. need

[0003] Its disadvantages are: 1. Long-term in this backward production mode, resulting in high labor intensity and many occupational diseases; 2. The process time is relatively random, and the product quality is unstable due to the judgment of the operator's experience; 3. The production is not stable. Continuous, low efficiency; 4. Large number of employees, low production efficiency
