Rewinder mechanical structure and control process ---

Fourth, summary
This chapter mainly introduces the mechanical structure of the double-backed roller rewinding machine, the working principle of the rewinding machine, the quality index and control performance index of the finished paper roll, and mainly analyzes the process of the rewinding machine from non-electrical convenience. Through the introduction of the quality index and control performance indicators of the finished paper roll, we can clearly understand that in order to optimize the quality of the paper roll, we understand the control system control objectives. Detailed analysis from the mechanism of operation: automatic program control of platen roller pressure; automatic program control of support roller torque; automatic tension control; electric drive "flexible" start and appropriate speed program control .

Belt rewinding machine design and working principle ---

3. Platen roller power:
A motor that drives the platen roller by a timing belt drive is mounted on the platen roller beam. The coupling between the individual bearings of the platen roller ensures that the speed of each combined reel is the same. The speed of each part of the platen roller is the same during operation.
Platen roller photocell:
There is a photocell at the end of the platen roller beam. If the paper or any other obstacle enters the photocell illumination area, the photocell signal will immediately stop the downward movement of the platen roller. During operation, the photocell's monitoring paper does not wrap around the platen roller. If something happens, the photoelectric signal activates the alarm to stop the rewind.
Core device:
1-trache
2- top core head
3- drive motor
4- positioning stop pin
5- Safety lock in the top core lock
The core between the drums is locked before the rewinding process begins. Keep the paper roll in place during the running of the paper core locking process.
Construction
The core lock device includes a paper core plug, a cone, and a sleeve. The core of the paper core is fixed in a core seat that can be vertically up and down and can reduce friction. The core of the paper core is supported by the upper bearing of the cone, so it rotates freely. The locking of the core and the upward movement of the core locking device are done hydraulically. The vertically moving hydraulic cylinder supports the weight of the core collet so that the home can rise as the diameter of the paper roll increases. The change in the slit width is adjusted with the help of the hydraulic transfer knob. The paper core collet has a relatively low position on the locating pin. As the paper core model changes, the latch and the paper roll chuck must change. The core collet structure has a shock absorber that is lowered onto the positioning stop pin at the core of the paper core. The safety lock has a compressed air cylinder open.
working principle 
Before the rewinding begins, the collet is knocked into the paper core. The locking cylinder of the operating side core collet has a locking pressure that is less than the drive side. If the core is too long, the operating side cylinder will retract. As the size of the paper roll continues to increase, the paper core collet moves with the paper roll, preventing the paper roll from moving laterally.
Before the paper roll is pushed away from the winder, the paper core chuck is unlocked and moved to the upper position. The appropriateness of the width of the paper core collet is related to the cutter positioning device. The sensor mounted in the paper core chuck records the pulse as the spool rotates. These pulse signals are not used to calculate the paper roll diameter. There is a sensor in each side of the cone. If one side of the sensor is damaged, the other side can be used immediately.

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.
