Daily maintenance and maintenance of the slitter:
First, the electrical parts should be cleaned and inspected regularly to remove hidden dangers in time.
Second, the use of slitting machines is done by slitting machines and cross-cutting machines. Therefore, high-quality slitting cutters and cross-cutting cutters are used.
Third, the daily maintenance of the slitting machine should be in place. The standard is that smooth, clean, clear (no dust, no debris) is in place to ensure that the sliding part of the equipment is in good condition.
Fourth, it is the maintenance work, and the regular and irregular inspections of the rotating parts should be stopped (especially the real-time monitoring of the wearing parts should be stopped). Regular adjustments are made, regular changes are made, commutators are carefully recorded, and the purpose of extending the service life of the equipment is achieved.
Fifth, improve the technical quality and degree of the personnel who operate the slitting machine. The control of the local operation must be done by a special person, and no one can operate it without any permission.
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 -
Third, through the film：
1. The cutter exits to the stop position. (The split knife switch is in the off position)
2. Press the “Pinch with chain” button and the hook and loop on the chain will run to the feeding position.
3. Press “Release Brake” until the indicator light is on, and the unwinder brake is released.
4. Pull one end of the film manually, pull the film along the running route to the film-piercing mechanism, and fix the film to the shackle of the chain.
