Rewinding Machine safety operation guide -
Fifth, the tool change operation:
1. The bottom knife replacement is handled by the mechanic.
2. The rewinding machine must be stopped when the upper round knife is replaced.
3. After removing the round blade, replace the new blade and fix it.
4. Install the round knife seat, adjust the angle, and lower the round knife to make it close to the bottom knife.
5, running, paper test knife, paper edge is not, smooth.
6. The tightness and depth of the blade and the bottom knife should be controlled properly, not too tight, otherwise the new knife
The film will roll the knife; it should not be too loose, otherwise it will jump the knife and the hair; not too deep, otherwise it will cause double trimming; too shallow will jump the knife.
Rewinding Machine operating procedures -
First, the boot process:
4. Press the gas up axis button to inflate the gas riser shaft;
5, adjust the position of the left and right correction sensor, so that the correction position is 50%, cancel the paper-like
6. Open the stop tension maintaining function;
Note: Before opening the tension, ensure that the product has no obvious relaxation;
7. Set the running tension and automatic running speed separately;
(1) The tension is set according to the characteristics of the product. The cigarette pack is generally about 45N, the most
Do not exceed 60N;
(2) The maximum running speed should not exceed 200m/min;
Rewinder mechanical structure and control process ---
Second, the main structure of the winder
2.4 Pressure mechanism
1, the platen roller
First, in the rewinder system, the platen roller has a significant impact on the tightness control of the paper roll. Among them, the pressure adjusting mechanism plays a role of keeping the pressure of the paper roll and the supporting roll nip constant, and the main purpose is to prevent the paper roll from slipping or being wound too tight at the beginning of the work. The paper roll slips because the paper roll is too light, and the winding is too tight because the pressure is too high until the rewinding to the later stage. In the modern rewinder system, the platen roller is automatically controlled, so that the paper can be additionally applied. The force.
2. Hydraulic (air pressure) suspension mechanism
Under normal circumstances, the adjustable pressure actuators use hydraulic suspension scale mechanism. We install a potentiometer attached to the platen roller to display the diameter of the finished paper roll, which is sent through the potentiometer. The signal is transmitted to the pressure program control unit to calculate the pressure, so that the oil pressure in the suspension scale can be changed, thereby achieving pressure control of the platen roller.
