Xiaobian for us to introduce the slitting machine is a kind of wide roll data longitudinal slitting equipment. So every profession has this word in use, we can understand from the scope of application.

for stripe paper category: this is now the mainstream product of packaging equipment, packaging shopping malls are often seen.

used for strip metal coil: such as strip steel, stainless steel, copper...... It is mainly used for steel processing manufacturers (steel market operators, steel rolling manufacturers, electrical appliances, cars, stamping parts, etc.)

It is used to strip leather, cloth, plastic, film and so on.

Xiaobian for us to introduce the structure of the slitting machine: by unwinding (unwinding), lead material positioning, slitting longitudinal shear, winding (winding) and other equipment. Its main function is to cut the wide roll data into narrow coils of certain size in the direction of length, so as to prepare for other processing processes in the future.

Division: reasonable layout, convenient operation, high degree of automation, high production efficiency, high precision, can process all kinds of cold rolled, hot rolled coil, silicon steel plate, stainless steel plate, color plate, aluminum plate and all kinds of metal plate after electroplating or coating.

Slitting machine application: widely used in cars, agricultural vehicles, containers, home appliances, packaging, building materials and other metal plate processing occupation.

Small make up for us to introduce the working principle of the splitter

Constant tension control principle

The essence of constant tension control in the process of winding and unwinding is to know the change of winding diameter at the side of the load in operation. Because of the change of winding diameter, in order to keep the load running, the output torque of the motor required by the split machine should change with the change of winding diameter. As for V series frequency converter, because it can do torque control, it can finish the control of winding constant tension. V series inverter provides three analog input ports, AUI, AVI, ACI. These three analog inputs can be defined as a variety of functions, so one of them can be selected as a given torque and the other one as a speed constraint. 0~ 10V corresponds to 0~ motor extra torque output by the frequency converter, so that the control of constant tension can be completed after adjusting the voltage of 0~ 10V. And Du Yu stripe machine, the part of the accounting roll diameter is calculated through the tension controller, of course, with PLC architecture to complete is no title. That is to say, after the tension can be set in man-machine or text, after THE PLC accounting coil diameter, T=F*D/2, so can calculate the torque of the motor output demand, after the analog output is connected to the torque of the given end of the V series converter can be.

Synchronous speed calculation

Because we know that when the frequency converter works at low frequency, the characteristics of the slitting machine to communicate with the asynchronous motor are not good, the activation torque is low and the division is linear, so in the whole process of winding, we should try to avoid the winding motor operation under 2HZ. Thus the rewinding motor has a minimum speed constraint. The synchronous speed of the four-stage motor is calculated as follows

Is the additional frequency,p is the polar logarithm,n1 is the synchronization speed

The speed limit is running

When the maximum winding diameter is reached, the lowest running speed in the whole winding process can be calculated:

PI.

Tension control, the slitting machine to speed constraints, otherwise there will be a flying car, so the speed limit operation.

Calculation of tension and torque

Assuming F*D/2=T/ I (F-- tension, D-- winding diameter, T-- torque, I -- reduction ratio), =F=2*T* I /D For a 3.7kW communication motor, the additional torque can be calculated as follows: T=9550*P/n=T= 24.88n.m So Fmax=2*24.88*9/0.6= 74.64n (T-- extra torque of the motor, P-- extra power of the motor, n== extra speed of the motor

The production line of the slitting machine is mainly composed of: feeding trolley, uncoiling machine, leveling machine, slitting machine, waste edge winding machine, tensioning machine, winding machine, unloading equipment, etc.
