Below in conjunction with accompanying drawing the utility model preferred embodiment is elaborated:
The linear velocity testing agency of dye jigger as shown in Figure 2, comprise first rotary encoder 5, second rotary encoder 6, first photoelectrical coupler 8 that is electrically connected with the output terminal of first rotary encoder 5, second photoelectrical coupler 9 that is electrically connected with the output terminal of second rotary encoder 6, the microprocessor 7 that is electrically connected with the output terminal of the output terminal of described first photoelectrical coupler 8 and second photoelectrical coupler 9, the display 10 that is electrically connected with the output terminal of microprocessor 7, wherein, described first rotary encoder 5 is installed on the output shaft of first motor 3 of dye jigger, referring to Fig. 1, described second rotary encoder 6 is installed on the output shaft of second motor 4 of dye jigger, microprocessor 7 adopts digital signal processor DSP, it has two data input ports, the data input port is corresponding is connected on the output terminal of the output terminal of first photoelectrical coupler 8 and second photoelectrical coupler 9 and the DSP two, display 10 is used for the object information that microprocessor 7 is handled is shown, so that test is more simple and clear.
Simultaneously, microprocessor 7 also has two output ports, this two output port respectively with the input end of first motor and driver element 3 and second motor corresponding connection of input end with driver element 4, microprocessor 7 is used for respectively to first motor and driver element 3 and second motor and corresponding voltage or the frequency signal source of the driver element 4 needed linear velocities of output.
The concrete course of work and control principle are as follows:
In dyeing process, first rotary encoder 5 and second rotary encoder 6 are gathered the rotational frequency f of first motor 3 and second motor 4 respectively in real time, microprocessor 7 receives by each photoelectrical coupler 8,9 image data that pass over, in conjunction with the linear velocity V1 of calculation of parameter first winding up roller 1 of its setting and the linear velocity V2 of second winding up roller 2, above-mentioned setup parameter comprises three, the optical path D0 of winding up roller, number of turns n1 on first winding up roller 1, number of turns n2 on second winding up roller 2, wherein optical path D0 is a constant, number of turns n1 and number of turns n2 can obtain automatically by dye jigger, and concrete computation process is as follows:
By kinematics as can be known,
V＝π＊f＊D＊J
Wherein: V is a travel line speed;
F is the motor gyro frequency;
D is the diameter of cloth on the cloth beam;
J is the reduction gear ratio of gear case;
By geometric knowledge as can be known,
D＝D0+2＊n＊δ
Wherein: D is the diameter for cloth on the cloth beam;
D0 is not for containing the cloth beam optical path of cloth;
N is the coiling number of turns of cloth;
δ is that cloth is thick;
The linear velocity V1 that sets first winding up roller equates with the linear velocity of the second winding up roller V2, i.e. V1=V2, and the above formula of substitution so,
π＊f1＊D1＊J＝π＊f2＊D2＊J，
Be f1* (D0+2*n1* δ)=f2* (D0+2*n2* δ).

V2＝J＊π＊f2＊D0＊(1+n2/(f2＊n2-f1＊n1))
Because dye jigger is when steady-state operation, be that tension force and linear velocity are when stablizing, driven roll linear velocity and the staining bath that cause heap cloth phenomenon faster than drive roll linear velocity can not occur, it is faster than driven roll linear velocity and tension bracket that cause shakes dancing back and forth the drive roll linear velocity also can not occur.At this moment, fabric guide roll and tension bracket keep constant angles, and the linear velocity of the linear velocity of debatching and last volume equates, this illustrates that first winding up roller, 2 linear velocity V1 equate at synchronization with second winding up roller, 2 linear velocity V2, but both equate synchronization, the not size of next both linear velocity constantly of meaning person and the linear velocity equal and opposite in direction of previous moment, because linear velocity constantly may be unequal in difference, then cause the different suffered tension imbalances of fabric constantly, thereby the homogeneity of influence dyeing, so need to guarantee that winding up roller also should be identical in different time line speed, thereby a linear velocity value of calculating constantly is different from one constantly instantly, need adjust the travelling speed of motor, therefore, microprocessor by the utility model testing agency is to the FEEDBACK CONTROL of first motor and driver element 3 and second motor and driver element 4, adjusts the input voltage of first motor and driver element 3 and second motor and driver element 4 or frequency to guarantee that dye jigger is in steady-state operation always.
