Rewinding Machine safety operation guide - 

Third, the rewinding machine opening and closing operation sequence:
1. Start the rewinding machine and the paper edge blower motor to put the speed to the crawling speed. Tearing the web
Into one. The paper edge is wound into a roller according to the specified path, and the round paper web must be straightened. Loosen and tightly adjust, press the switch and the paper core tube to stick the tape. Stick the paper web to the paper core tube and start crawling. At the same time, the end of the paper roll is flat. The paper can not be wrinkled or discounted to ensure the quality of the rewinding. When the paper has broken ends, the joints are operated, the broken ends are connected and the joint quality is ensured.

Rewinding Machine safety operation guide - 

Eight, pay attention to safety matters:
1. When unloading the paper roll, pay attention to whether there is someone in front.
2. Pay special attention to safety when using the paper feed roller
3. It is strictly forbidden to pass over the top of the head when lifting the paper roll, and check the firmness.

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.
