Rewinding Machine common fault - Rolls are not collected
1. The original coil is not uniform - Finish the original coil to ensure that the original coil is neat
2, paper core size head - check the paper core
3, only start a short period of time - normal phenomenon,
4, bearing damage - bearing damage is often accompanied by abnormal noise, pay attention to check the bearing, found that the damage is replaced in time
5, shaft damage - contact the manufacturer
Rewinding Machine operation safety regulations -
Fifth, machine maintenance and hygiene
1. After the production is completed, first adjust the governor to zero, close the program switch, and finally turn off the power of the control box;
2. Use the air duct to blow the inside and outside of the machine and the electric box, and do not place any debris such as tools in the machine and the electric box.
3. Regularly repair and maintain the rotating parts of the machine (add some amount of oil or butter)
4. The hygiene of the machine area must be cleaned.
5. The waste paper is sent to the pulping station of the designated paper mill. The original paper core is neatly stacked in the specified paper barrel stacking area according to the specifications. The leather tape, waste paper and waste paper core are placed in the designated stacking area.
6, with the machine repair to do the regular maintenance of the machine main maintenance work.
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.
