Novel integrated electric cabinet of coarse spinner

Abstract

The invention discloses a novel integrated electric cabinet of a coarse spinner, which is characterized in that: a 380V three-phase power line L1, a power line L2 and a power line L3 are connected with a frequency converter V through a breaker QF5, and the frequency converter V is connected with a motor M3 by a lead; the power line L1 is connected with one end of a primary coil of a transformer T through a breaker QF1 by a lead, the power line L2 is connected with a button SB4 and the other end of the primary coil of the transformer T through a breaker QF2 by a lead; and the 220V voltage of a secondary end of the transformer T is connected with a connection terminal L of a programmable logic controller (PLC) through a breaker QF3, the 12V voltage of the secondary end of the transformer T is connected with an indicating lamp HL1, an indicating lamp HL2, an indicating lamp HL3, an indicating lamp HL4 and an indicating lamp HL5 through a breaker QF4, and the grounded terminal of a secondary coil of the transformer T is connected with an earth wire N of the PLC and the connection terminals of the power line L2 and the power line L3.

Description

technical field [0001] The invention relates to A454 type roving mechanical and electrical control equipment, in particular to a novel integrated electric control cabinet for roving frames. Background technique [0002] In the electrical equipment of the existing A454 type roving frame, the electrical control is still a circuit board assembled with old-fashioned discrete components. For example, the type A454 type roving frame not only has many functional components connected to it, but also the system is complex, unreliable and inefficient. Affect product quality, its main structure is to use a reactor to reduce the voltage to prevent roving details in spinning, externally connect a separate infrared photoelectric controller and counter; after the equipment is started, the reactor connected in series in the main circuit of the motor plays the role of balancing the circuit current , the motor can only start slowly, and cannot run at high speed immediately, which will cause u...

Problems solved by technology

[0003] In order to solve the shortcomings of the existing A454 type roving frame technology, the present invention provides a new integrated electric control cabinet for the roving frame. Yarn prevention details, yarn escape, yarn metering, photoelectric self-stop in one

It overcomes the existing three-phase voltage and current imbalance that makes it difficult to start the equipment, the life of the motor is shortened, and the yarn details cannot be prevented when the machine is shut down. The electric control cabinet adopts PLC programmable controller as the control core, and the frequency converter controls the transmission motor. , displayed in Chinese, realizes real-time online monitoring and adjustment of electromechanical control integration
