Rewinding Machine safety operation guide -
First, prepare for work after taking over:
1. It is necessary to arrive at the post, check, and original record 15 minutes earlier. Comprehensive understanding of the above
The operation of a class of equipment, the quality of rewinding and safety.
2. Understand whether the previous class of paper is good; whether the class changes specifications, the weight and change
time. Check if the shift is cleared in the previous shift.
3, the middle and night shift rewinders must check whether the rewinding paper core tube and packaging materials are adequate.
4,Report the handover to the squad leader
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:
1. Adjusting mechanism of pressure of the platen roller
As the rewinder continuously performs rewinding, the diameter of the finished paper roll is gradually increased, and the weight of the finished paper roll is also gradually increasing, so that the contact points of the finished paper roll with the front and rear bottom rolls are also changing. So you can come to a conclusion like this:
If the pressure of the platen roller is kept constant and does not change, the pressure between the contact points of the finished paper roll and the front and rear bottom rolls is not guaranteed to be constant, and the change in the contact point causes the pressure generated between them to change accordingly. Therefore, if we want the paper roll to reach the best form, we must adjust the pressure exerted by the platen roller to compensate for the influence of the above two factors. Only in this way can the pressure between the front and rear bottom rollers and the finished paper roll be guaranteed. Variety.
2, support roller torque program control In the rewinding process of the finished paper roll, in order to obtain high quality finished paper roll, the speed control or the support roller torque should meet certain conditions, if the speed control is used, the support roller The speed between the two should be less than 0.2%. As the diameter of the paper roll increases, the speed of the two supporting rollers must be close. Only in this way can the high quality finished paper roll be rewinded, but some quick checking systems cannot consider this design.
