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 ---

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.

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.
