2. Quick Detail:
This Calendar line is able to produce a wide range of PVC film and sheet products for different applications. The line is composed of φ410×1200mm roller “Γ” type 5-roll Calendar, 150 planetary extruder, and together with up-stream and down-stream auxiliary equipment.
3. Description:
(1) The material of the cylinder 1#, 2#, 3# is Alloy Chilled Cast Iron,
its hardness is HS68-72,cylinder 4#, 5# is forging by extra fine steel, its hardness is HRC58, the
parameter of the roller is φ 410x1200,the pulsate of roller’s surface is less than 0.01mm(after finishing
the adjustment of calender)
(2) The cylinder 1#is canulate, 2# ,3# is used to drill round, chromium-plated on the surface of the roller, and surface roughness is above Ra0.20; cylinder 4#,5# is used to drill
round, and surface roughness is above Ra0.05( specular )
(3) Main drive is the high precision, small gap combinatorial gearbox.
This speed reducer is special use for plastic hard piece rolling. We manufacture them according to
ZBJ19004-88. The accuracy of gear grinding is number 6, superior alloy steel. Smoothly gearbox
transmit, low noisy(less than 80 db), high accuracy in stability. Drive by universal coupling, its maximum
linear velocity of cylinder is 30m/minute.
(4) The driving motor is variable-frequency motor.
(5) The bearing of the roller is with high temperature resistance, high
precision (class D).
(6) We have deal with the rack and base many times,make sure the accuracy requirement. We use the
stainless steel to wrap the rack and beam.
(7) Roller 1#, 2#, 3#, 4#, 5# is heated up by heat transfer oils. The gap between roller and roll surface
is tiny. The rollers are all with the Oil-filled swivel joint, metallic hose.
(8) Roller1#, 2#, 3#, 5# is the motor-driven clearance take-up mechanism.
4. Applications:
Fix(Six) Roll Calender is Applicated in producing high grade rigid transparent PVC sheet, colorful PVC
sheet, flexible PVC sheet,such as food package,medicine package and other uptake plastic container.

6. Competitive Advantage:
a. The rollers are drilled roll with hot-grinded, single motor single transmission with a stable and adjustment speed work. The machine use roller bearing which can bear high temperature. Sealing type is labyrinth.
b. The film can infinite extend, with a high work speed, high produce capacity, good quality and uniform thickness.
c. The main machine has roll crossing, preloading and anti-bending device, the nip adjustment speed can be adjusted, the electric parts has PLC control.
