The negative pressure control device for an induced draft motor of a bobbin winder controls negative pressure valve of the air duct of the machine to a constant target value, reduces wastes of electric energy, prolongs equipment service life and reduces failure rate and equipment maintenance cost for enterprises.
Description
Technical field
The utility model is a kind of negative pressure control apparatus, particularly a kind of bobbin-winding machine induced-draught electric motor negative pressure control apparatus that is used in.
Background technology
In the prior art, the automatic winder device for dischanging air provides negative pressure of vacuum for single ingot suction nozzle and cop storehouse, this device drives a centrifugal compressor by a two-pole machine by the V-type transmission and produces, negative pressure near 6500pa, in actual production process because the mass discrepancy of different yarn variety, make the operation of suction nozzle that different requirements be arranged, when the joint number of elements reduces, under the situation that motor is operated at full capacity, cause waste of electric energy, many times because misoperation makes the air channel poor sealing, cause the long-term overload running of motor, make easily that the motor feels hot, destruction of insulation has increased maintenance cost.
Chinese patent CN200946058 discloses a kind of transmission control device of bobbin-winding machine, by the servo-driver of high speed processing chip, contains CN1, CN2, CN3 three sockets, L1, L2, U, V, W, R, S, T terminals; The servomotor that has coder is connected with CN2 and U, V, W end; By frequency converter, AC induction motor and coder connect and compose the coiling motor, are connected with CN1; By frequency converter, AC induction motor connects and composes the overfeeding motor, is connected with CN1; Also have an alignment sensor and a thickness transducer, constitute a transmission control device.The utility model is by the cross motion of servomotor formation with by the coiling motion that frequency converter connects and composes, and promotes the bobbin-winding machine motion, makes coiling and cross motion meet the technological requirement of permanent tension force perseverance linear speed.The negative pressure of machine is controlled on the constant aim parameter, when joint reduces, causes waste of electric energy easily, increase the error rate of equipment, increase the maintenance cost of enterprise.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provide a kind of negative pressure value in machine air channel that makes to be controlled on the constant aim parameter, reduce waste of electric energy, the service life of minimizing equipment and error rate reduce the bobbin-winding machine induced-draught electric motor negative pressure control apparatus of enterprise to the maintenance cost of equipment.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of bobbin-winding machine induced-draught electric motor negative pressure control apparatus, comprise control desk, be provided with blower fan and motor in the described control desk, a side and blower fan corresponding section at control desk are provided with airduct, blower fan connects motor by lead, and described control desk is provided with frequency converter, and frequency converter is connected by lead with motor, described airduct is provided with pressure transformer, and pressure transformer is connected by lead with frequency converter.When the force value in the airduct changes, pressure transformer is delivered to frequency converter to signal by signal wire (SW), frequency converter is delivered to the signal of negative pressure in the motor by power lead, motor impels the rotation of blower fan, by the residual quantity of airduct negative pressure feedback quantity signal and aim parameter signal is carried out ratio, integration, is differentiated, adjust the frequency converter output frequency, constitute feedback system, constant when keeping the negative pressure in the airduct.
As preferably, described frequency converter is arranged on a side of control desk, and described frequency converter is connected with motor by power lead; Described pressure transformer is plugged on the airduct, and pressure transformer is connected with frequency converter by signal wire (SW).Signal wire (SW) is used to transmit the negative pressure signal of pressure transformer, and power lead is used for controlling the rotation of motor.
As preferably, the upper end of described blower fan is provided with evacuation port, and described evacuation port is connected with blower fan; Described blower fan, motor, pressure transformer and frequency converter form closed loop control by lead.Evacuation port is used for airduct is vacuumized, and makes airduct keep the state of negative pressure.
