Rewinding Machine safety operation guide -
Fifth, the tool change operation:
1. The bottom knife replacement is handled by the mechanic.
2. The rewinding machine must be stopped when the upper round knife is replaced.
3. After removing the round blade, replace the new blade and fix it.
4. Install the round knife seat, adjust the angle, and lower the round knife to make it close to the bottom knife.
5, running, paper test knife, paper edge is not, smooth.
6. The tightness and depth of the blade and the bottom knife should be controlled properly, not too tight, otherwise the new knife
The film will roll the knife; it should not be too loose, otherwise it will jump the knife and the hair; not too deep, otherwise it will cause double trimming; too shallow will jump the knife.
Rewinding Machine operating procedures -
Two: shutdown process:
1. Click the “Stop Detection” button and use the ICW program “Shutdown”;
2. Turn off the detection system switch;
3. Turn off the total power switch of the winder;
4. Close the total air valve.
Rewinder mechanical structure and control process ---
Third, the rewinding machine control performance indicators
The rewinder is the last process in the papermaking process. The performance of the rewinder determines the quality of the finished paper roll. A complete rewinder must have the following properties:
3. Tension adjustment mechanism
It is generally believed that web tension control is one of the important factors affecting the tightness of the paper roll. The most important function of flattening the paper web during the rewinding process is the web tension, and the web tension must be kept stable before the paper can be avoided. The lateral movement of the web allows the rolled out finished paper roll to meet the requirements. However, the web tension is only affected when the finished paper roll is rolled up. Since we are using a double bottom roller lower paper rewinding machine, the paper web must pass through the back bottom roller to be wound on the paper roll. The roller will isolate most of the tension, and only a small amount of tension can be transferred to the finished paper roll, which means that if there is tension to control the hardness of the paper roll, if the hardness of the paper roll changes little, The tension will change a lot. The key factors affecting the hardness of the paper roll are the pressure of the platen roller and the torque difference between the front and rear bottom rollers. The effect of the web tension on the hardness of the paper roll is not great because it is not a critical factor. 4. Electric drive "flexible" start and proper speed program control The starting of the winder is of course smoother and better, so that the paper web can be prevented from being subjected to the impact of tension, and the breakage can be reduced and the paper roll can be improved. Rewind quality. In order to meet such requirements, we often add a given integrator to the speed and current of the speed regulation system. This is beneficial to the start of the winder. Through analysis, we can know that if the system is to start more smoothly, give The larger the time constant of the integrator, the better, so the integral time constant of a given integrator can be adjusted over a large range to suit the processing requirements.
From the above four points, we can see that the electronic control system must have adjustment skills to meet the rewinding process.
