Tape slitting machine technical parameters
One: Introduction to tape slitting machine
The slitting machine mainly divides the large-rolled master roll into products of different widths and can check the quality of the product. Its main features are as follows:
1. Unwinding photoelectric correction, high precision; divided into two files: manual and automatic
2, there can be two ways of winding: surface winding and center winding;
3. The unwinding tension adopts automatic tension;
4, round knife cutting, reliable quality, easy to adjust;
5, using the surface center winding, the winding quality is even and stable;
6, the fixed length automatically stops, the length automatically counts the meter;
7, has a trimming device, the edge material is discharged by the fan;
8. Particularly suitable for slitting of narrow strips (insulating materials, mica tapes, films, etc.)
Main way of tension control
The tension control method is generally divided into two types: open loop control mode and closed loop control mode. The open loop control is to directly drive the winding mechanism with an electric motor having a similar winding characteristic n = kD (n is the rotational speed, k is a constant, and D is the diameter of the winding roller) to obtain an approximate constant tension operation. The open loop control has poor randomness and low control precision. The closed loop tension control has two kinds of direct tension control and indirect tension control. In the actual production process, the volume is adjusted, that is, the tension is fed back, compared with the given tension, and then the difference is applied to the regulator to adjust the controlled object so that the output tension meets the actual demand. It is called direct tension closed-loop control. This method can eliminate the steady-state error without considering various compensations. The indirect tension control uses the motor speed-torque characteristic curve to control the torque to control the torque, so as to achieve the purpose of controlling the tension. This method requires dynamic and static compensation. Sometimes, in order to obtain more precise control performance, a composite tension control method is adopted, that is, the required control amount is first determined according to an indirect control algorithm, and various compensations are considered to make the indirect control as accurate as possible, and then the direct tension control is used for fine adjustment.
Slitting machine operating procedures -
Second, the volume of the replacement of the finished product (operating station)
8. Operate the button on the winding arm to wind up the paper core.
9. Manually cut the film to be cut onto the corresponding rewinding paper core. After tightening the film, it is firmly adhered to the paper core (note that the side 1 and side 2 films are differently worn).
10. After all the paper cores on both sides are glued, press “Crop 1 Clamp” and “Reel 2 Clamp” at the same time, and then press “Rewind side 1 open” and “winding side 2 open” at the same time. The position is automatically swung until the winding paper core is pressed against the upper roller, the winding main body is started, and the film is slowly wound until it is tight. (The two-button white indicator light turns from blinking to steady light)
11. Press the “MACHINE” button, the siren will sound and the signal light will flash yellow. Confirm that the personnel are in the safe area, press "machine on" again, the button light is always on, the machine starts and accelerates to the input set speed.
12. The main operator shall check the winding condition of each film and fine-tune the winding arm if necessary.
