Description
Technical field
The utility model relates to a kind of frequency-changing control system of spinning equipment, especially a kind of metering pump of spinning machine high-precision control system.
Background technology
It spinning-drawing machine is the major equipment of spinning industry, volume pump is the important metering outfit on spinning-drawing machine, current metering pump of spinning machine is gear-type pump, operationally, external power supply drives volume pump to rotate, and melt sucks between the tooth paddy of volume pump gear, and the inwall being close to horizontal 8 word grooves at the band ejector half of gear is discharged after returning and circling, discharge the amount of melt to change according to the rotating speed of volume pump, discharge melt amount number determine the thickness of monofilament.Current spinning-drawing machine generally there are several volume pumps; adopt same Induction Motor-Driven; when often there is work, because of frequency jitter, rotation speed change causes the wire diameter of monofilament to fluctuate; several volume pump rotating speeds simultaneously on same spinning-drawing machine are identical; the melt amount of ejection is also identical, and same spinning-drawing machine can only produce the product of same specification, affects manufacturing schedule adjustment; there is fault that maintenance occurs to need all to shut down, have impact on normally carrying out of production.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of metering pump of spinning machine high-precision control system is provided, the each volume pump on spinning-drawing machine is controlled by the control system that high precision frequency converter and permagnetic synchronous motor form, often overlapping control system can corresponding each volume pump, the amount of volume pump melt can be adjusted by the setting of operating frequency, can according to the POY monofilament of need of production production plurality of specifications on a spinning-drawing machine, there is fault that the normal operation of other spinning machine equipment occurs not affect when need overhaul, waste huge in producing can be avoided.
For achieving the above object, the technical solution of the utility model is: a kind of metering pump of spinning machine high-precision control system, comprise air switch, frequency converter, permagnetic synchronous motor, volume pump, shaft coupling, outside input power cord has P, S, T three-phase, by the input port of power lead access air switch, the output port of described air switch respectively connects power lead and connects with described inverter input mouth, described inverter output terminal mouth is connected with the input power port of described permagnetic synchronous motor, described permagnetic synchronous motor axle body end installs shaft coupling, described shaft coupling is connected with the axle head of volume pump.
Further setting, described shaft coupling is high precision elastic shaft coupling.
The beneficial effects of the utility model are: drive with frequency converter and permagnetic synchronous motor, the rotating speed of volume pump can be made to set as required very easily, and can ensure accuracy requirement and the invariablenes turning speed of volume pump; When certain volume pump or drive motor fault, only need corresponding frequency converter to quit work, the normal operation affecting whole spinning-drawing machine can be avoided, avoid the huge waste in producing; Single cover drive system controls single metering pump, greatly can reduce the capacity of drive system, reduce manufacturing cost and maintenance cost; Every suit drive system can set separately operating frequency to determine the melt flow of volume pump, is convenient to the POY monofilament of an anti-plurality of specifications of spinning function, greatly can reduces failure rate, is also convenient to the alternately normal and new product development produced.
Accompanying drawing explanation
Fig. 1 is mounting structure of the present utility model and use principle figure.
In figure: input power cord 1, air switch 2, frequency converter 3, permagnetic synchronous motor 4, volume pump 5, shaft coupling 6.
