company news about How to correctly understand the slitting machine?

The cutter shaft of slitting machine knife shaft, on its diameter φ 120mm (H7), the effective length of cutter shaft is 650mm, and the key width is 16mm; Material 40Cr forging, quenching and tempering HB240 ∽ 260, rough machining, medium frequency treatment, grinding, hard chromium plating, and then grinding; The tool shaft runout on the slitter equipment shall not be greater than 0.02mm, and the shaft shoulder runout shall be less than 0.01mm（The cutter shaft specification is matched according to the model).

The cutter shaft of slitting machine is driven by universal coupling (2 pcs), synchronous gearbox and power by AC15KW frequency conversion speed regulation (motor power is matched). The synchronous gearbox is welded with steel plate. After qualitative treatment, the bearing hole is precision machined by boring machine, and the gear will be forged with 40Cr, Quenched and tempered HB247∽278 and quenched HRC38∽45. When the cutter shaft is locked, the cutter will be locked with a nut, and there is one left and one right screw nut respectively; In terms of blade diameter, that is ф 240mm (matching the actual size of cutter shaft).

Constant tension control principle in slitting machine. For the essence of constant tension control in the process of winding and unwinding, it is necessary to know the change of winding diameter during the operation of load. Due to the change of winding diameter, in order to maintain the operation of load, the slitting machine also needs the output torque of motor, which should change with the change of winding diameter. For V-series frequency converter, the torque control can be done, so that the control of recoiling constant tension can be completed.

Constant tension control in slitting machine provides three analog input ports, AUI, AVI and ACI, for its V-series frequency converter. In this regard, the three analog inputs can be defined as multiple functions. In this way, one can be selected as the torque setting and the other as the speed limit.

For the constant tension control in the slitting machine, the 0 ~ 10V corresponding frequency converter outputs 0 ~ motor rated torque. At this time, the constant tension control will be completed by adjusting the voltage of 0 ~ 10V. However, for the slitting machine, the part of calculating the coil diameter must also be calculated through the tension controller, but there is no problem that it must be realized with PLC architecture.
