3, unloader
Nowadays, with the increase of the speed of the winder, most of the winders are equipped with unloaders, which are used to push the rolled paper rolls from the support rolls and unload them on the ground. It has many forms, the most common ones are the unwinding station and the unwinding pendulum. Its control mainly depends on air pressure or hydraulic pressure. The thief of the unwinder can be selected according to the number of operators, the size and quality of the core. The advanced foreign rewinding machine can automatically control the positioning of the mandrel and mandrel and the cutting of the paper, which can save auxiliary operation time and improve production efficiency.
4, transmission mechanism
The speed of the paper-feeding machine of the winder is generally about 15 to 40 m/min. In the process of raising the speed of the paper from low, we require the speed of the vehicle to rise, so that the paper roll can be avoided due to the fluctuation of the tension. The tightness is inconsistent. Uniform acceleration is required for breakage or shutdown. During the acceleration process, the average acceleration is usually 0.23~0.37m/s, and the acceleration time is usually 50~60s. In the braking process, the deceleration is 0.42~0.75m/s and the braking time is 40s. In order to meet the shifting requirements of the winder, most of the rewinding opportunities are driven by DC motors. In the previous rewinding system, a DC motor generally controlled two supporting rollers, and in the current rewinding machine, Development and research have started with two separate motor control rolls, which can control the speed difference between the two rolls, which is beneficial for taking up the appropriate tightness of the paper roll.

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.

Measure the diameter of the exit roller.
The diameter measuring sensor or the super-sonic sensor is fixed on the floor in the middle of the paper exit. The sensor measures the diameter of the reel as the reel becomes smaller in the rack position.
