Fig. 6 shows a kind of control circuit schematic diagram suitable for the embodiment of the present invention, and details are as follows:
In embodiments of the present invention, the cooperation between transmission device and yarn storage device is controlled by control circuit, the control circuit
Include:
Switch module 601, including the power switch S1 for controlling Thread-feeding device power supply, and the outside for switching output state
Control switch S2；
Power supply module 602, the power supply module are used to provide working power for the control circuit, be controlled by the power switch S1
System；
Signal pre-processing module 603, the signal pre-processing module can guarantee the non-polar access circuit of signal；
Output state control module 604, the output state control module receive the signal of the signal pre-processing module transmission,
And realize the switching of the control circuit output state；And
Two output circuits, described two output circuits are identical and form interlocking, control institute by the output state control module
State the output state of two output circuits.
As an embodiment of the present invention, control circuit mainly controls the interlocking action of two electromagnetic coils in Thread-feeding device,
I.e. when the electromagnetic disc in transmission device is powered on, the electromagnetic disc in yarn storage device will not be powered on, and the two only has at one
In operating mode, meanwhile, by the circuit control in the control circuit, realize that electromagnetic coil is being powered on state for a long time
Under, substantially athermic function.
As the present invention as shown in fig. 6, the power supply of Thread-feeding device control panel is entered by AC1, AC2, S1 in PCB circuit board,
Default is short circuit welding, therefore, when AC1, AC2 have power supply to enter, after D1 rectifier bridge carries out rectification C2 filtering, obtains direct current
Power supply+24v1 powers to entire circuit.At this point, the control switch of S2 is in an off state, D4 non-transformer passes through, therefore, U2, U4
It does not work.Because there is power supply to pass through, U3 starts to work to be connected U3, and Q2A obtains control signal, and Q2A conducting provides U1 and Q2B
Power supply, at this point, Q2B controls signal because control foot is influenced by C1, R1, R2, Q1 delay circuit formed, when Q2A is obtained,
Q2A conducting, when providing power supply to U1 and Q2B, Q2B is first connected (100ms time, determined by C1, R1, R2, Q1), directly that U1 is short
It connects, so that OU1 obtains the power supply energy output of total power, driving electromagnetic coil work.After 100ms, Q2B does not work, at this point, U1
It is not controlled in the short circuit by Q2B, the output of OUT1 is directly determined by U1, at this point, the driving power that OUT is obtained is full voltage constant current
The driving of 1/3 electric current, because constant electrical power is constant, current reduction 2/3, thus when realizing that electromagnetic coil is powered for a long time, substantially not
The design requirement of fever.Meanwhile because supply voltage is constant, so, the torque maintenance of electromagnetic coil remains unchanged.And it is powered
Moment is full voltage total current mode, so, electromagnetic coil can produce the magnetic field of sufficient intensity in the moment of starting, be attracted
Clutch-plate movement.When S2 is closed the switch, because D4 obtains electric, U2 and U4 conducting, at this point, the defeated of U3 is directly closed in the conducting of U2
Out, so that Q2A does not work, OU1 does not obtain working power.U4 conducting, then Q4A obtains control signal, and Q4A conducting, Q4B and U are obtained
Driving power is obtained, Q4B controls signal because control foot is influenced by C4, R9, R11, Q3 delay circuit formed, when Q4A is obtained,
Q4A conducting, when providing power supply to U5 and Q4B, (100ms time, determined by C4, R9, R11, Q3) is first connected in Q4B, directly by U5
It is shorted, so that OU2 obtains the power supply energy output of total power, driving electromagnetic coil work.After 100ms, Q4B does not work, at this point,
U5 is not controlled in the short circuit by Q4B, and the output of OUT2 is directly determined by U5, at this point, the driving power that OUT2 is obtained is full voltage
The driving of 1/3 electric current of constant current, because constant electrical power is constant, current reduction 2/3, thus when realizing that electromagnetic coil is powered for a long time, base
This athermic design requirement.The interlocking working condition of OUT1 and OUT2, is determined by the on-off of S1.The output of OUT1 and OUT2
State is total power output or the output of 1/3 electric current of full voltage constant current, and the switching of state is determined by respective rear class delay circuit
With conversion time.
The embodiment of the present invention realizes the interlocking action of electromagnetic disc by control of the control circuit to two electromagnetic discs, guarantees
Synchronism and yarn storage device between transmission device and yarn storage device are not in the shape that unintentional rotation leads to yarn breakage or release
Condition guarantees device steady production.
