Rewinding Machine safety operation guide -
Second, the rewinding machine is opened and shut down:
1. Check the equipment thoroughly before starting the machine to check whether the round knife and the bottom knife are in good condition.
2. Whether the size of the round knife meets the requirements of finished products and cutting specifications
3. Hang the rewinding paper roller on the paper feeding frame, and make the brake and roller contact with each other.
Whether the fuse cover on both sides of the core and the barrel of the core is covered.
Rewinding Machine operating procedures -
First, the boot process:
1. Turn on the total power of the rewinder and the power of the detection system in turn; Note: (1) Before turning on the power, please make sure that the circuit is connected correctly and there is no short circuit;
(2) When the main power is turned on, an alarm will occur. After about 5 seconds, after resetting through the touch screen, turn on the detection power.
2. Turn on the air source switch, please ensure that the air pressure is around 6Mpa;
3. According to the paper-feeding direction in the machine state of the touch screen, the product is paper-punched; Note: (1) Please select the paper-feeding state before putting on paper;
(2) Ensure that the core is in the middle position of the inflation shaft, and the core is installed on the left and right gas rise shaft
The same location;
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.
