Featurers of Model CL-80/100/80H-1500mm
1.Strong Double Layer Vacuum Box Device
Strong Double Layer Vacuum Box Device helps absorb the hot air between film and cooling roller,which makes the film be more closed and tightly to the cooling roller thus enhance the cooling effect when the machine is running in high speed.
2. High Quality and Updated Advanced Cooling System
The cooling roller's diameter is 1000mm with bi-directional loop design and helix runner inside.The high-precision steel is adopted to ensure stable temperature on roller surface.
3.Melting Pump--Plastic melt metering pump is more and more important in extrusion process, especially in high-end products industries, such as high quality sheets, pipes, BOPP, optical cable.Installing the melt metering pump in the cast stretch film unit can make the machine produce constantly and efficiency. The pump can improve the product quality, stable the production process and decrease the energy consumption.
4.Four Air Shaft Roll Changers Device
One roll change takes only 30 seconds and this system can help produce small hand roll online when the machine is running in high speed.And so there is no need to install a rewinding machine to rewind,which helps save a lot of time, cost and labor.
Plastic melt metering pump is more and more important in extrusion process, especially in high-end products industries, such as high quality sheets, pipes, BOPP, optical cable.
Installing the melt metering pump in the cast stretch film unit, which can keep the production constantly and efficiency. The pump can improve the product quality, stable the production and decrease the energy consume.
The housing is made of chromium-nickel alloy or nickel-base alloy, titanium alloy. The gear is made of quenching chromium steel, other metal materials are also applicable. Bearing is made of graphite NIAG, zirconium oxide or quench tool steel.
FAST AND STABLE FLOW SUPPLY
Eliminated the extruder`s pulsation wave. Improve the product quality, decrease the defective rate, and decrease the waste, which can save 2% material and 25% of the unit power consumption.
STABLE AND EFFICIENCY PRESSURE CONTROL
The melt pump can provide a stable pressure, which short the discharge time obviously and make the production effectively.
INCREASE THE EXTRUDER OUTPUT AND THE MACHINE LIFE
It has been found that after install the melt pump, the max pressure wave value is the pressure after pump. Which can make the inner pressure of the extruder decrease, the melt shear strength decrease, the temperature curve gently, and restrain the temperature rising. Also the melt pump can avoid the damage to the extruder from the high pressure.
Main Technical Specification of CL-80/100/80H-1500mm
(Such as plastic film machinery.)
(1) Overall Dimensions(L*W*H): 14m*6.5*4.45
Max width of rewinding: 500mm*3
Max Rewind Diameter: ø400mm
Liner speed of machinery: 350m/min
(2)Rewind the film by combining it`s surface and core to make the film roller tightly closed and level and smooth.
(3)Remove the film roller and install the paper tube at the same time, which only takes about 25-30s and produce 2-3kg small film roller when the machine is running in high speed.
(4)Automatic edge material recycling system with on-line vacuum makes the process of rewinding more smooth, increases the fracture resistance, and decreases the limitation by liner speed.
(5)The recycling materials are extruded out from only and specific screw to stable the the extrusion system and to decrease the deviation about the weight of film.
(6) The extrusion machine is driven by coupling which stables the extrusion process and therefore stables the film output from die head.
(7)Prompt measurement to adjust the thickness and uniformity of the film easily.
