Rewinding Machine Structure - Longitudinal Section
In the mechanical system of the winder, the slitting mechanism is a very important part of the winder. In order to ensure a straight and smooth cutting edge, the quality control of the finished paper roll plays an important role in ensuring the volume. It is easy and can reduce the fluffing during printing.
The slitting mechanism should be installed as close as possible to the paper roll so that it can produce a lateral movement more than necessary during the process of cutting the web without curling.
Four release and one rewinding machine operation program ---
Fifth, sorting out
1. After the work is finished, turn off the power and put the main power switch down.
2. Clean up the work area.
1. It is necessary to add oil to the bearings.
2. Use a manual grease gun to add butter to the bearing of the belt shaft once every six months; when the gear is missing butter, pay attention to add butter.
1. The winder has certain dangers, so it is necessary to pay attention to safety during operation.
2. Never touch the ultrasonic probe on the pressure roller.

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.
