Protective Film for Aluminium Profiles Surface Protection coating
We draw into foreign advanced coating machine technology and
together with our own many years of experience . The machine adopt
gravure roller coating method, it widely used in the production of
car explosion proof membrane, building explosion proof membrane,
solar film, coloring, release film, anti-static film etc
Main technical parameters:

|unwinding and dia.||electrical turn type,φ600mm|
|rewinding and dia.||back-depend type,φ500mm|
|coating speed||10-60m/min(depending to the material)|
|heating method||conduction oil cycle heating method|
|overall machine motor power||about25KW|
1 overall machine adopt 3 frequency motor control.
2 electrical rotation double station unwinding frame, adopt
magnetic powder auto control the tension
3 gravure coating method, coating doctor blade shaft adopt heavy
double shaft machine independent moving, blade adjust by manual
with pneumatic, angle adjust freely, coating quantity depend the
mesh of gravure roller, different coating quantity can change
different mesh gravure roller.
4 in order to get the uniformity effect,the machine adopt one set
uniformity roller,control by motor frequency.
5 oven is 16m control temperature independently, heating adopt
conduction oil exchanger air intake drying system, adjustable inner
cycle air intake and out device, air intake and out with strong air
, dry thoroughly.
6 oven inner guide wheel is active synchronous with the mainframe,
drive adopt synchronous belt drive guide wheel to assure
synchronous to reduce material stretch and deformation, cylinder
pneumatic open oven and film pass operation panel so that worker
can work very easily.
7 the tension between coaitng roller and traction steel roller
adopt float swing arm by PLC auto-control
8 auto-length and speed meter device
9 webguide adopt EPC air sensitive register to assure the trimness
10 rewinding and unwinding adopt key type airshaft for easily
operate when loading and unloading the material
11 high presicion up press traction device, steel roller cooling
adopt water cycle to make the film surface more smooth and neat. to
reach good cooling effect.
12 rewinding frame is back-depend type,the rewinding drive
synchronous with traction.
A According to the different requirements of the customers special
the customized machine (limited width of 300-2000mm)
B rewinding and unwinding frame : manual lift up type single
station, hydraulic lift type single station, electrical rotation
double station, electrical chain climbing type double station,
electrical rotation wheel pan type double station can be choosed by
C oven heating method: electric heating, conduction oil heating,
steam heating etc can be choosed by customer
D coating method: gravure roller coating, double rollers coating,
three rollers coating, five rollers coating, comma blade coating,
air knife coating etc can be choosed by customer
E work speed is proportion with coating material quality, coating
thickness, oven length, drying temperature
