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.

Belt rewinding machine design and working principle ---

2 rear bottom roller
The roller is covered with a steel shell. It maintains a dynamic balance at a speed equivalent to the design speed. The roller has a coating and a spiral groove. Equipped with hydraulic brake system. The roll outer coating is used to attempt to increase the friction between the roll surface and the paper during rewinding. Air is discharged along the spiral groove between the roll surface and the paper roll.
Vacuum drum
The rear bottom roller has a hole. Vacuum suction is generated by a blower. This facilitates paper machine threading to ensure that the cut sheet fits snugly against the roll during roll change.
(traction) platen roller device:
1-cylinder safety valve
2- Pressing roller
3- Press roller safety lock
4- Photocell
5- Pressing roller beam
6- Paper roll
The platen roller is used to hold the paper roll during the roll paper process. The pressure between the roller and the drum is adjusted by adjusting the pressure of the platen roller. The rewinding pressure affects the roll density and sheet tightness and winding force. In addition, the platen roller ensures that the paper roll is in an adapted position.

9 small paper rolls launched
The small paper roll ejecting device is used for those paper rolls that are too small for the paper feed roller. The small paper roll ejecting device is mounted on the paper feed roller. It relies on hydraulic pressure to move. The minimum diameter that the small paper roll exit can be pushed out is 200 mm (7.9 in).


10 paper cutter construction
The paper cutter is a zigzag blade, which cuts the slit webs during roll ejection. The paper cutter rises from the paper roll to the paper cutting position. The movement of the paper cutter is done by a lever driven by a hydraulic cylinder.
working principle 
The paper roll is pressed against the raised paper cutting blade by the ejector pin and cut.


11 core positioning pin
The end of the core loader is a paper core locating pin attached to the rewinder frame. The paper core positioning pin includes a metal plate and a frame. The scale on the core locating pin shows the position of the locating pin. The paper core locating pin holds the paper core in the correct position on the core loader only by the edge of the slitter. The core positioning pin is placed in close proximity to the slit and is locked in that position by the locking arm.
