Applications:

Four Roll Calender is Mainly used in calender line for manufacturing soft PVC products such as banner,.

clothes packing bag,wrapping film,plastic floor,PVC leatheroid,etc.

Main character

SY610-4Γ1830 type four roller calender and auxiliary equipment

A.   Calender (host machine)

1.    Calender: feed material from top and make final production from bottom, roller diameter Ф610 mm, roller surface width 1830mm, the surrounding drilling and oil heating, line speed of the calender 5-50m/min. The piece coming out from the roller of the calender has display apparatus gap of rollers distance. Right driving.

Rollers

2.    1# and 2# rolls are cold-cast alloy roller and surrounding drilling, surface hardness HS68-74 ° C, the rollers’ surface hard chromium plating fine grinding, coating thickness 0.1mm, the rollers surface roughness Ra = 0.05μ, surface comprehensive precision 0.01mm;

Material of 3# and 4# rollers is alloy forging flaw detection processing, the rolls’ surface hard chrome plating, coating thickness 0.18mm, hardness> HRC60 ° roll, surface roughness Ra = 0.01μ, surface comprehensive precision 0.05mm, roll surface temperature no less than 230 ° C, the roll surface temperature error ± 1 ° C;

1-4# rollers surface had no middle height, 1-4 # rollers all surrounding drilling, roller surface chromium plating without pinhole, the roller polished and process degassing after fine grinding.

3# and 4# rollers hard chrome plating after hot mill processing.

Bearing

3.    Bearing use the Wafangdian production taper bearing, bearing pedestal use ductile iron.

Transmission and power

4.    Drive power of 1# roller and 4# roller of Calender: 55KW (in this calender main and auxiliary equipment use AC motor), and the remaining 2# and 3# roll: 75KW power. Main and auxiliary can tune speed by linkage and also division. (Calender is equipped with blackout emergency opening device, UPS devices purchased by buyer). The motor of calender adopts AC motor speed regulation, Siemens Beide motor, Japan Yaskawa governor, other electricals adopt Shanghai Schneider.

Controllable pitch

Controllable pitch device: setted at 1, 2, and 4# roller. The 3 # roller is fixed roller.

Axis crosses

5.    calender 3# roller mounted shaft cross-device, cross regulation 20mm, adjust the speed 3mm/min, driving drive: at each end with a three-phase brake motor of planetary reducer of, worm gear, use adjusting spindle to control crossover amount, universal ball joint head between the spindle and the bearing pedestal, on the other side use the universal ball joint head and hydraulic cylinder to connect, the hydraulic cylinder is used to locate and eliminate transmission parts clearance.

Pre-bending

6.    4# roller has pre-load device, installed in the outside of the main bearing of 4# roller, positive bending, embody bending by hydraulic cylinder, the bending amount is adjustable, embodied by adjusting a hydraulic pressure, the maximum bending amount is equivalent to the roll height 0.05mm.

Rack

7.    The calender rack uses 40mm steel plate welded after heat treatment and then finishing, the roller face and rack wall open file 15 cm according to bearing, stainless steel rack. Distance between the stripping roller and 4# rollers is 5mm.

Lubricating

8.    roller bearings lubricated with thin oil forced circulation lubrication device for roller bearings and bending bearing lubrication, automatic cycle, dual-pump system (one pump for work and one pump for spare), pressure-protecti
