Abstract
The utility model discloses a frequency automatic setting system of a delinter seed feeding mechanism. The frequency automatic setting system comprises a frequency converter driving a seed feeding motor. The current main speed instruction end of the frequency converter is connected with an external current input circuit. The external current input circuit is connected with a current detecting device for detecting currents of a seed poking motor so as to input current signals for controlling the speed of the frequency converter. According to the frequency automatic setting system of the delinter seed feeding system, reliable seed feeding can be achieved.
Description
Technical field
The utility model relates to a kind of delinter hello seed mechanism frequency and sets up system automatically.
Background technology
In existing domestic cotton processing technique field, delinter is the parts that mainly short flannel on the hair seed stripped down, and generally its motor of feeding seed mechanism is all manually set up frequency converter and fed the seed frequency and realize.Known, because therefore the viscosity of hair seed after manually setting up hello a seed frequency, following problem may occur.: at first be to feed the idle running of seed motor, but do not have mao seed to be fed to the situation of stripping seed roller; Another problem is if hello seed frequency is too big, the electric current of stripping seed motor or mandrel motor is risen until the gambling commentaries on classics, even burn out motor.
From foregoing description as can be known, under existing configuration, allow hello seed be in suitable amount and give full play to the best condition of shelling seed motor and mandrel motor is the comparison difficulty.
Summary of the invention
In view of this, a kind of delinter of proposal of the present utility model is fed the system that seed mechanism can automatic frequency adjustment, thereby realizes feeding reliably seed.
The technical solution adopted in the utility model is:
A kind of delinter is fed seed mechanism frequency and is set up system automatically, comprise and drive the frequency converter of feeding the seed motor, the electric current master speed command end of described frequency converter is connected with the foreign current input circuit, this foreign current input circuit connects for detection of the current detecting equipment of dialling the seed current of electric, with the current signal of input control frequency converter speed.
From said structure as can be seen, according to the utility model, the electric current of dialling the seed motor is sampled, control the output of frequency converter with the electric current of dialling the seed motor, owing to dial the front side that the seed motor is positioned at the delinter structure, both direct correlation, therefore, the reliability of this control mode is very good.
Comparatively speaking, group seed two is directly reflected into to dial and is positive correlation on the seed motor, thereby can satisfy the basic demand of control automatically effectively, than the mode of manual setting frequency converter frequency, operate simplyr, it is also more reliable to work, and can therefore not produce and block up, safeguard more convenient.
Above-mentioned delinter is fed seed mechanism frequency and is set up system automatically, and described current detecting equipment is to be installed at the current transformer of dialling on the seed motor main circuit.
Above-mentioned delinter is fed seed mechanism frequency and is set up system automatically, also is provided with the electric current digital display meter on the described external circuit input circuit.
Above-mentioned delinter is fed seed mechanism frequency and is set up system automatically, and described foreign current input circuit inserts described electric current master speed command end by on-off circuit, with the break-make by on-off circuit, described frequency converter is changed under open loop and closed loop two states.
Description of drawings
Fig. 1 is the wiring diagram of frequency converter.
Fig. 2 arranges electrical schematic diagram for current transformer in dialling the seed motor circuit.
Among the figure: 1, electric current digital display meter, 2, frequency converter, 3, feed the seed motor, 4, current transformer, 5, dial the seed motor.
Embodiment
Feed seed mechanism frequency with reference to a kind of delinter shown in the attached Fig. 1 and 2 of explanation and set up system automatically, its conventional configuration section is to feed the seed motor 3 configuration frequency converters 2, Fig. 1 medium power line U3, V3, W3 output connect feeds seed motor 3, just the motor M among the figure 3 obviously also can be passed through the manually frequency of adjustment frequency converter according to said structure.
During frequency converter is controlled automatically, can adopt electric current master order, also can adopt voltage master order, adopt electric current master order herein, the electric current master speed command end of arranging at the control terminal of frequency converter 2 is connected with the foreign current input circuit, by the frequency conversion of foreign current control frequency converter, and then this foreign current input circuit connection is for detection of the current detecting equipment of dialling seed motor 5 electric currents, with the current signal of input control frequency converter speed.
In content as previously shown, provide group seed motor 5 and have certain relevance with hello seed motor 3, can control effectively according to this relevance and feed seed motor 3, avoid hello seed motor 3 to occur blocking up or other problems.In some applications, rise when dialling seed motor 5 electric currents, feed the seed frequency and descend automatically, when electric current drops to a certain degree, feed the seed frequency and rise automatically, reach the automatic adjusting that delinter is fed the seed frequency.
Current acquisition is relatively common in electricity, and contact collection and contactless collection are arranged, the collection that for example utilizes near the magnetic field of circuit to carry out, and obviously this dual mode can be applied in this programme.
Preferably, described current detecting equipment is to be installed at the current transformer of dialling on seed motor 5 main circuits 4, utilizes contactless collection also easily existing equipment to be transformed, and adjusts, overhauls all very convenient.
Further, as shown in Figure 1, also be provided with electric current digital display meter 1 on the described external circuit input circuit, it is used for current transformation on the one hand, can provide operation information intuitively for the operator on the other hand.
In order more effectively to debug, described foreign current input circuit inserts described electric current master speed command end by on-off circuit, with the break-make by on-off circuit, described frequency converter 2 is changed under open loop and closed loop two states.
As Fig. 1 and Fig. 2, manual knob SZ is chosen manual, set the suitable seed frequency of feeding, this frequency shows at the frequency converter panel; After finishing previous step, manual knob SZ is chosen automatic transmission, delinter is benchmark with this frequency of manually setting, adjusts automatically.
After selecting hello seed motor to feed the seed shelves automatically, dial seed motor 5 electric currents among Fig. 2 and change; Dial the variation of seed motor 5 electric currents and pass through 0 ~ 5A electric current of mutual inductor 4 among Fig. 2 as the input signal of electric current digital display meter 1 among Fig. 1, electric current digital display meter output current is 4 ~ 20mA.
4 ~ 20mA electric current of electric current digital display meter 1 output is as the input signal of frequency converter 2 then, and frequency converter 2 is calculated the corresponding output frequency of input signal values by calculating, drives and feeds seed motor 3, finishes the purpose that the seed frequency is fed in automatic adjusting.
