Roll unwinding unit

1. Main unwinding shaft adopts pneumatic core shaft, making it easy for position alignment of material loading. Loadable film diameter≤φ**0mm, width≤***0mm, both sides of unwinding device are equipped with pneumatic locking device

2. Unwinding tension is equipped with magnetic powder brake（*5Nm）and roller type encoder for speed measurement together to carry out automatic control, unwinding tension infinitizes the size of roll diameter, meanwhile, unwinding device is equipped with pneumatic tension floating rollers.

3. Unwinding traction roll device keeps accordant with frequency conversion motor (3.7KW) for material output to ensure stable material feeding.  

4. Unwinding shaft of upper unwinding device adopts pneumatic core shaft, and meanwhile equipped with automatic deviation correction device. Tracking electric eye for deviation correction  can carry out  micro-adjustment.    

5. In the process of mono-unwinding, materials will enter in a horizontal way with automatically photoelectric control for film edge correction, making it effective tracking and micro-adjustment for printing materials or non-printing materials. Monolithic materials will enter the V-shaped metal sheet for segmentation. 

(1) Balance of tension

Equipped with regulating device for opposite sides combination between upper &lower layers. Floating tension roller as well as pneumatic tension adjustment will transform continuous feeding into stepping feeding, making material output more effective, equipped with film edge slitting device. They keep balance with traction tension, making material ametabolic and stable conveying.

(2) Vertical sealing unit

1. Three groups of corresponding heat sealing and cooling devices from top to bottom are available for independent adjustment by horizontal movement and linear adjustment by unidirectional cutter.

2. Contactless thermostatic control
