Power-saving control system of double housing planer

Abstract

The invention discloses a power-saving control system of a double housing planer, which comprises a cabinet body, a main loop unit, a frequency converter VVVF control unit, a programmable controller (PLC) input and output unit, a cutter lifting and indicating lamp unit and a relay protection unit, wherein all the units are arranged in the cabinet body; a main circuit is connected with a lubricating motor RB, a vertical turret motor C, a right turret motor Y, a left turret motor Z, a cross beam lifting motor H and a cross beam clamping motor J through circuit breakers 1QF-7QF and contactors 1KM respectively; the frequency converter VVVF output is connected to a main motor M; and the PLC input and output unit consists of an input part and an output part. The power-saving control system of the double housing planer has the advantages of simple structure, strong reliability, convenient speed adjustment, energy conservation, running speed improvement and cutting efficiency improvement, and can be widely applied to cutting mechanical equipment.

Description

Technical field [0001] The invention relates to a control device, in particular to a new type of power saving control device for a planer. Background technique [0002] At present, the electrical control device of the planer is composed of a DC generator set. Most of them are driven by a DC generator set to rotate the DC motor, that is: (AGM) method. Its working feature is the high-speed round trip of the worktable, which is used to process various planes and end faces of large workpieces. , Inclined plane and trough. However, with the improvement of the technical level, these traditional control methods increasingly show their shortcomings and deficiencies, such as large equipment, high energy consumption, large maintenance volume, long maintenance cycle, and only simple and fixed machinery for speed regulation Moreover, the impact on the power grid and the machinery itself is severe, which seriously affects the service life and accuracy of the planer. In particular, it is very...

Problems solved by technology

However, with the improvement of the technical level, these traditional control methods are increasingly showing its shortcomings and deficiencies, such as huge equipment, high energy consumption, large maintenance volume, long maintenance cycle, and can only be adjusted by simple and fixed machinery. And it has a great impact on the power grid and the machine itself, which seriously affects the service life and accuracy of the planer. In particular, it is very easy for the workpiece to rush out of the machine bed, causing a series of problems such as personal and mechanical accidents, and it is increasingly unsuitable for modern times. Due to the requirements of processing technology, the original control device needs to be improved urgently
