Rewinding Machine structure - Ejection Department
In the rewinder system, we installed the paper roll on the paper exit frame. In order to ensure that the width of the sides of the paper web is the same, we should be moving the seasoning when
the paper roll is ejected. But the paper roll in the new structure can move with the paper exit frame,
This ensures a greater rigidity of the exit frame. In addition to manually moving the paper roll, we can also use the pneumatic, photoelectric device and electric method to adjust the axial movement
of the paper exit frame, so that the cutting edge of the winder can be narrowed, and the manual adjustment can not be achieved. Requirements.
Four release and one rewinding machine operation program ---
Fifth, sorting out
1. After the work is finished, turn off the power and put the main power switch down.
2. Clean up the work area.
1. It is necessary to add oil to the bearings.
2. Use a manual grease gun to add butter to the bearing of the belt shaft once every six months; when the gear is missing butter, pay attention to add butter.
1. The winder has certain dangers, so it is necessary to pay attention to safety during operation.
2. Never touch the ultrasonic probe on the pressure roller.

Second, the main structure of the winder
2.3 Rolling Department
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.
