Basic knowledge of rewinder
Rewinding machine is one of the most common adhesive tape equipment, mainly used for complex rolled up material roll materials, the most basic requirement is after rewinding can maintain the characteristics of the original material, but not the appearance of wrinkles and bubbles.
The rewinder can be divided into single spindle rewinder, double axle rewinder and shaftless rewinder;
It can also be divided into sticky material rewinder, non sticky material rewinder and so on.
1., two paragraph control rewinding length; automatic brake stop;
2. unwinding tension automatic control, winding tension control;
3. arched roller expansion material, limited to remove wrinkles;
4. embossing shaft transfer material, Teflon for anti sticking treatment;
5. use silica gel roller to remove bubbles, the pressure can be adjusted, so that rewinding material is suitable for tightness;
Introduction of shaftless rewinder:
Shaftless winder using surface rewinding way, can be used in a variety of different diameter of the inner hole of the tube core complex volume of material, so the use of a relatively wide range; can also be used for rewinding of transparent material, especially suitable for rewinding OPP ultra transparent tape, PET protective film etc..
Introduction of biaxial rewinder:
The rewinder adopts two winding switching type rewinder, when one winding when rewinding operation, another for tubing or unloading operations, and therefore such rewinding machine is the most efficient, is the theory of single shaft winder two times.
The difference between a viscous material rewinder and a cohesionless material rewinder:
The working principle of the two types of rewinder is basically the same, but there are many differences as follows:
1. viscous material rewinder adopts Teflon pressure rachides transfer material, without viscous material rewinder is not can use these rollers;
2. the non cohesive material rewinder needs to be assembled with EPC to correct the offset of the material, and the viscous material rewinder can not use the device, otherwise the material will be entangled together due to the viscous action;
3., the sticky material rewinder is usually an integral structure, and the non cohesive material rewinder is an independent structure, which is divided into two parts, the material deviation rectifying table and the rewinding host
