Rewinding Machine Structure - 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 is slippery because the paper roll is too light and the take-up is too tight because the pressure is too high until the rewinding to the late stage. In the modern rewinder system, the platen roller is automatically controlled so that additional weight can be applied to the paper web. 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 passed to the pressure program control unit,
To calculate the pressure, so that the oil pressure in the scale can be changed, thus achieving the pressure control of the platen roller.
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 safety operation guide -
Seventh, production operations and quality control during the rewinding process:
1. The speed must be slow when rewinding, and the inspector should check the appearance quality of the paper.
2, often check the quality of the paper, found that the paper disease stopped in time, to the inspector on duty
Report and contact the upper and lower processes to strip off paper with quality problems. The rewinding can be continued after the inspector confirms.
3. When rewinding, pay attention to the situation of broken ends, trimming, etc., and control the tension of the paper during rewinding.
The car is tight) to keep the inner and outer tension of the paper roll consistent.
