Abstract
The utility model provides a frequency conversion energy-saving control device used for a winding machine negative pressure system which comprises a negative pressure box, a wind suction motor and a control system, and is characterized in that the control system comprises a frequency conversion speed governor and a pressure sensor, the load end of the frequency conversion speed governor is connected with the power input end of the wind suction motor, the pressure sensor is installed in an air duct of the negative pressure box, and the electric signal output end of the pressure sensor is connected with the frequency setting signal input end of the frequency conversion speed governor. The frequency conversion speed governor has the PID regulation function. When the winding machine carries out single spindle knitting circulation, the power of the wind suction motor is increased, the wind suction volume is increased, the suction head efficiency is enhanced, and the production efficiency is enhanced; when the winding machine has no single spindle knitting circulation or the knitting circulation is reduced, the power of the wind suction motor is reduced, the rotation speed is lowered, the abrasion to the motor is reduced, the vibration intensity of the motor is weakened, and the service life of the motor is relatively prolonged, thereby the purposes of energy conservation and consumption reduction are achieved.
Description
Technical field
The utility model relates to the improvement of the control setup of Weaving device bobbin-winding machine, belongs to Weaving device manufacturing technology field, is a kind of bobbin-winding machine negative pressure system energy-saving and frequency-variable control setup specifically.
Background technology
The purposes of spinning equipment bobbin-winding machine is except the tube yarn that incidental looping is become to have certain-length and require, another vital task is removed exactly to back operation and the influential all kinds of harmful yarn defects of final finished quality, lacks thigh, rattan sth. made by twisting etc. to improve yarn appearance quality as big cotton knot, slubbing, details, ring, two yarn, strand.
The negative pressure system of bobbin-winding machine (comprising negative pressure box and induced-draught electric motor) provides single ingot suction nozzle and the required vacuum of cop feed rake, be the indispensable parts of bobbin-winding machine, domestic and international existing novel bobbin winder is to control negative pressure by the program that microcomputer system is set, and the part bobbin-winding machine can't carry out programming Control owing to the restriction of former software system at present, thereby cause induced-draught electric motor under the fully loaded state, to turn round for a long time, the motor that weares and teares is on the one hand wasted electric energy on the other hand.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, a kind of bobbin-winding machine negative pressure system energy-saving and frequency-variable control setup is provided, can increase or reduce the rotating speed of induced-draught electric motor automatically, thereby reach energy saving purposes according to bobbin-winding machine list ingot knotting situation.
The purpose of this utility model is achieved by the following technical solution:
A kind of bobbin-winding machine negative pressure system energy-saving and frequency-variable control setup, comprise negative pressure box, induced-draught electric motor and control system, it is characterized in that: described control system is made up of variable-frequency governor, pressure sensor, the load end of variable-frequency governor is connected to the power input of induced-draught electric motor, pressure sensor is installed in the air channel of negative pressure box, and the electrical signal of pressure sensor is connected to the frequency setting signal input end of variable-frequency governor.
Described variable-frequency governor is the variable-frequency governor with PID regulatory function.
The on-off signal mouth of described variable-frequency governor is connected with a buzzer phone.
The utility model compared with prior art has the following advantages and good effect:
The utility model has been formed closed loop control system by variable-frequency governor, pressure sensor and induced-draught electric motor, and frequency converter automatically adjusts to the blower fan negative pressure according to the PID Principles of Regulation, makes the negative pressure expected value keep stable, and has stronger adaptivity.When bobbin-winding machine list ingot knotting circulation time, increase the power of induced-draught electric motor, suction air volume strengthens, and suction nozzle efficient improves, and the red light amount reduces, and production efficiency has also just improved thereupon; When bobbin-winding machine does not have single ingot knotting circulation or knotting circulation and reduces, reduce the power of induced-draught electric motor, rotating speed reduces, and the wearing and tearing of motor are reduced, and the motor oscillating strength reduction prolongs service life of motor relatively.Thereby reach energy saving purposes.
Description of drawings
Fig. 1 is the schematic diagram of the utility model bobbin-winding machine negative pressure system with the energy-saving and frequency-variable control setup;
Fig. 2 is the circuit diagram of the utility model bobbin-winding machine negative pressure system with the energy-saving and frequency-variable control setup.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of bobbin-winding machine negative pressure system comprises negative pressure box, induced-draught electric motor 3 and control system with the embodiment of energy-saving and frequency-variable control setup, and described control system is made up of variable-frequency governor 2, pressure sensor 1.The load end of variable-frequency governor 2 is connected to the power input of induced-draught electric motor 3, pressure sensor 1 is installed in the air channel of negative pressure box, the electrical signal of pressure sensor 1 is connected to the frequency setting signal input end of variable-frequency governor 2, the on-off signal mouth of variable-frequency governor 2 is connected with buzzer phone 4, and described variable-frequency governor 2 has the PID regulatory function.
When reality was used, the PID that at first sets variable-frequency governor 2 regulated target frequency and alert frequency, and the value of this target frequency should be guaranteed the wind speed of induced-draught electric motor 3, made negative pressure box produce enough negative pressure, guaranteed that bobbin-winding machine list ingot knotting circulation is normal.After bobbin-winding machine entered normal working, variable-frequency governor 2 was regulated the output frequency that changes variable-frequency governor 2 according to the detected value of pressure sensor 1 feedback by PID.If single ingot knotting number of times is few, variable-frequency governor 2 output frequencies reduce, and the speed of induced-draught electric motor 3 reduces; When single ingot knotting number of times increased, variable-frequency governor 2 output frequencies increased, and the speed of induced-draught electric motor 3 improves, and suction air volume increases, thereby satisfies the requirement of bobbin-winding machine normal operation.If variable-frequency governor 2 has reached delivery at full capacity, normally the waste wool case has foreign material to stop up, and annunciator 4 will be worked, and in time sends chimes of doom prompting operation person and clears up the waste wool case.
Avoid induced-draught electric motor 3 to flog a dead horse like this, prolonged the service life of induced-draught electric motor 3, reduced energy consumption.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
