Belt rewinding machine design and working principle ---

1 belt roller device
Structure
The belt and stick set consists of two belt rollers with intermediate and end supports! A rubber support belt surrounds the belt roller. The inner surface of the support belt has a guiding profile that controls the operation of the belt. There is also a correspondingly concave surface on the belt roller. The belt roller has been joined together by a rocker and a hydraulic cylinder from below. The belt tension can be adjusted with a hydraulic cylinder during the winding process.
The motor drives the rear belt roller to run, and the other roller is carried by the belt. The belt roller is equipped with a hydraulic brake system. The belt roller bearing housing is lubricated with lubricating oil. The oil flow and temperature of the lubricating oil system are detected by the sensor. There is a directional blow tube between the two rolls to ensure that no space remains in the space between the two rolls. The lifting device has been installed under the belt. The lifting device is used for changing rolls. The lifting device comprises a hydraulic cylinder and a lifting plate interlocked with the rear bottom roller during the lifting process.
Belt roller unit:
1- bottom roller
2- rear belt roller
3- front belt roller
4- belt
5-belt telescopic hydraulic cylinder

Principle of operation
The core is placed between the back bottom roll and the back belt roll. The paper core is supported at that position throughout the initial crimping process up to a diameter of approximately 500 mm (17.9 in). The over 500 mm (17.9 in) belt begins to support the increasing area of ??the paper roll, and the weight of the roll is reached when the paper roll is particularly large. Mainly supported by a belt.

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.
