Rewinding Machine common fault - The platen roller does not move
1. Proportional valve is unstable. - Clean the proportional valve or replace the proportional valve to adjust the amplification signal.
2. Control failure - on-site debugging of the instrument.
Rewinding Machine operation safety regulations -
Fourth, other requirements in the production process
1. Rolling paper or paper jam of a certain part of the machine must be stopped. Use the jog function to remove the paper. The original paper should be carefully operated when it passes through the embossing device, the crimping device, the paper feed roller and the punching knife. It is strictly prohibited when the machine is running. Wipe and refuel the rotating parts in the state to avoid injury accidents;
2. During the production process, the gears, pulleys, chains and other components of the machine must not be allowed to entangle with paper scraps, ropes, etc., and the air pipe must not leak. The trachea, electric wires, etc. can not be fixed with rope or adhesive tape, which affects the appearance;
3. The waste paper can not be thrown anywhere in the production process, must be loaded into the designated waste paper bag to keep the production site clean.
4. The original paper core produced during the production process must be placed in the designated place;
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.
