Rewinding Machine common fault - Longitudinal cutter swing
1. Round knife bearing wear - Replace the bearing.
2. Tool holder sliding bearing wear - Replace the bearing.
3. Lock the cylinder leak - replace or repair the cylinder.
Rewinding Machine operation safety regulations -
Second, the operation steps：
1. According to the production order of the day, the squad leader is responsible for arranging the material production (base paper, packaging materials, paper core);
2. Check whether the quality of the original paper texture, color, tension, elongation and other products meet the product requirements.
3. Put the original paper on the paper-removing shaft and the shaft plug must be locked. The 1575 rewinding machine is assisted by the handyman to push the original paper to the unloading frame and push it into the positioning slot. The 2900 rewinding machine uses the cylinder to lift the paper. Push the rear frame into the positioning groove of the rear frame (when the iron shaft is pushed into the positioning groove, pay attention to safety), and adjust the left and right position. When replacing the base paper, the shaft stalk and the plug must be removed with both hands and placed on the ground. It is strictly forbidden to throw or fall on the ground, and damage the floor or hurt the person;
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.
