Sticker Paper Slitting Machine

Sticker Paper Slitting Machine

The rewinder is a special equipment for mica tape and film. The rewinding process mainly accomplishes three tasks: first, cutting off the raw paper burrs; second, cutting the whole original paper into 
a plurality of widths in accordance with user specifications; Third, control the winding diameter of the finished paper roll to meet the factory specifications.

 

Advantages of the winder
1, equipped with processing unintentional, solid, paper tube toilet paper, can instantly switch between products. 2, automatic trimming, glue spraying, sealing, and the shaft is instantaneously synchronized, so that the paper is transferred into the band saw and the paper is not damaged when it is cut.
3. Pneumatic belt feeding, double reel and each axis of the original paper have independent tension adjustment mechanism.

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.

2.4 Pressure mechanism
1, the platen roller
First, in the rewinder system, the platen roller has a significant impact on the tightness control of the paper roll. Among them, the pressure adjusting mechanism plays a role of keeping the pressure of the paper roll and the supporting roll nip constant, and the main purpose is to prevent the paper roll from slipping or being wound too tight at the beginning of the work. The paper roll slips because the paper roll is too light, and the winding is too tight because the pressure is too high until the rewinding to the later stage. In the modern rewinder system, the platen roller is automatically controlled, so that the paper can be additionally applied. The force.
2. Hydraulic (air pressure) suspension mechanism
Under normal circumstances, the adjustable pressure actuators use hydraulic suspension scale mechanism. We install a potentiometer attached to the platen roller to display the diameter of the finished paper roll, which is sent through the potentiometer. The signal is transmitted to the pressure program control unit to calculate the pressure, so that the oil pressure in the suspension scale can be changed, thereby achieving pressure control of the platen roller.
