10. a kind of closed loop conduction band stepping control of conduction band type inkjet printing machine as described in claim 1-9 any claims
The conduction band stepper control method of system processed, it is characterised in that：The step of conduction band stepper control method, is as follows：
1）Driving motor starts, and driving roller device rotation is driven by driving motor, drives conduction band movement by driving roller device, leads
With the work before driving motor starts of the clamping device in shifting quantity detecting device, conduction band is clamped, with conduction band synchronizing moving, and
Directly measure the displacement of conduction band；
2）When the displacement that conduction band shifting quantity detecting device measures conduction band reaches scheduled conduction band stepping-in amount, conduction band amount of movement
Detection device generates a feedback signal and is transmitted to drive motor controller, after drive motor controller receives this feedback signal,
Drive motor controller sends out a signal to driving motor, driving motor operation suspension, conduction band pause movement；
3）When conduction band needs to move again, drive motor controller sends out another signal to driving motor；
4）Repeat step 1）To 3）.
11. the conduction band stepping of the closed loop conduction band step-by-step control system of conduction band type inkjet printing machine according to claim 10
Control method, it is characterised in that：When conduction band shifting quantity detecting device is completed to detect with conduction band synchronizing moving and controls a stepping
After amount, when conduction band remains static, clamping device in conduction band shifting quantity detecting device is temporarily detached from conduction band, conduction band shifting
Momentum detection device resets to initial position, and when conduction band needs mobile, conduction band shifting quantity detecting device again clamps conduction band, uses
In the stepping-in amount for directly measuring conduction band.
