Magnetic powder brake, magnetic powder brake generates brake force and is transferred to aluminium strip charging tray generation braking effect by chain, when aluminium strip pulls
When lift adjustment roller rises along linear axis, the brake force of magnetic powder brake reduces, conversely, when aluminium strip pulls lift adjustment roller edge
Linear axis decline when, the brake force of magnetic powder brake increases, reliable and stable, is not in that feedback leads to disconnected band situation not in time
There is a situation where long service life, failure rate is low, can satisfy the needs of stable material-supplying.In addition, can by moving bedplate handwheel
Adjustment drives moving bedplate to be moved forward and backward, the center so as to adjust aluminium strip charging tray with respect to lower steering roll, when without material sensor
When issuing without material signal, then system is automatically stopped operation.
(2) the utility model eliminates reset cylinder and is wherein playing the role of pneumatic spring, therefore structure is simpler, examination
It tests and shows after eliminating reset cylinder, when aluminium strip pulls lift adjustment roller to rise excessive along linear axis, rectilinear transducer
Generated excess in displacement variation can be by electric signal transmission to the tension controller of rolling band fin machine, to control lift adjustment
Roller relies on self-weight reset, guarantees that aluminium strip maintains smooth, tensioning appropriateness and the stable state of feeding.
