Product Description

calender roll machine for thermal paper

1,Main data:

1.1 Trimed sheet width: max 6000mm

1.2 Operating speed: max 1500m/min

1.3 Paper threading speed:

1.3.1 off-line operating:5~15 m/min

1.3.2 online operating: the same as PM and coater.

1.4 Working liner pressure:max350N/mm

1.5 Thermal roll surface temp:180ºC

1.6 Number of calendering rolls:6~12

1.7 Top and bottom roll type: multi-zone controllable crown roll

1.8 Thermal roll: shell material: alloy chilled cast iron. Surface hardness:HSD72; surface temp variation±1ºC.

1.9 Soft roll: roll cover is imported, done by special manufacturers.

1.10 Calendering roll loading and releasing style: bottom tank loading,and releasing. The loading oil tank is controlled by PLC. Quick releasing and slow releasing. calendering roll quick releasing time ≤0.5s

1.11 Calendering roll weight hydraulic compensating system: hydraulic entire or sectional compensation.

1.12 Thermal roll heating system: Electrical heating, body temp linear control.

1.13 The heads of soft roll is cooled by blowing.

1.14 Paper release type( off-line): constant tension control motor brake to release paper. Under emergency stop, motors generate electricity to brake. Max unreel tension: 0.7~1.5N/mm.

Reel change flying connecting speed:20~30m/min

1.15 reel type: constant tension control, float loading shaft type( off-line). Max reel tension:0.7~1.5N/mm

1.16 Paper threading: separate threading.

1.17 Drive: AC frequency conversion sectional drive. Expect the main drive, the other calendering rolls and some leading rolls, spreader rolls are equipped with auxiliary deive.

1.18 Electrical and hydraulic control system:

1.18.1 Main drive, reeling and unreeling drive are AC frequency conversion variable-speed The reeling and unreeling drive are equipped with special operation card and tension detecting feedback system. Reel and unreel emergency braking tome: 5~10s.

1.18.2 Auxiliary drive s speed and load distribution control.

1.18.3 The oil pressure of bottom roll and controllable crown roll is controlled by PLC. The oil pressure can be tracked automatically according to the setting linear pressure.

1.18.4 The reel loading linear pressure can be adjusted separately.

1.18.5 Through PLC and field bus, control the machine operation and hydraulic system logic operation. All the operation can be done through the touching screen. The operation plant is equipped with buttons, knobs and indicator lights.

1.19 Inside and outside lifting table: hydraulic drive, machinery synchronization, equipped with electrical, hydraulic, machinery safety device.

1.20 Crane: used for roll changing and maintaining.

1.21 Others.

2,Main feature:

2.1 Large frame and base plate are high-quality steel plate welding, machining after annealing. The frame has high-strength, good rigidity and quality, good-looking appearance. The frame is installed with base plate, which can insure the installing accuracy and reduce installing period.

2.2 Paper releasing stand, upright, rail upright of the lifting table, auxiliary drive support and spare roll support are steel plate cold bend section bar welding, with good-looking appearance and symmetry structure.

2.3 Calendering roll quick and slow separating control technology, to insure the safety and reduce the shock.

2.4 The multi-zone controllable crown roll can control the sheet caliper smoothness variation, to enhance the product quality.

2.5 The calendering roll weight hydraulic compensation technique changes the drive arrangement form, control the two sides difference precisely, improve the calendering result greatly, enhance the production capacity and extend the service life.

2.6 Separate paper threading is the fundamental change for the super calender operation.

2.7 Thermal roll consists of chilled cast iron body and two flange shaft heads. The body is drilled surround to form the thermal oil channel. The special design can insure the uniform surface temp.

2.8 Soft roll consists of intermediate body and two flange shaft heads. The cover material is imported, done in domestic. The body is equipped with stainless steel liner interlayer, forming the fluid flow passage with flange shaft heads and double-pass rotary joint, keep the soft roll working.

2.9 The spreader roll use composite bidirection multipoint spiral groove structure. When sheet width is large, it is better to use three-section variable spreader roll.

2.10 Thermal roll oil heating use conduction oil electrical heating system. The roll body temp use linear control system. Main parts and electrical control elements are imported.

2.11 Electrical control system is word famous brand.

2.12 In order to keep advancement and reliability, the following parts are imported:

2.12.1 Soft roll cover.

2.12.2 High-pressure oil pump, proportional valve, sensor, pipe joint, hydraulic steel pipe, high-pressure tube in the hydraulic control system.

2.12.3 Controllable crown roll and hydraulic sealing elements.

2.12.4 Thermal oil rotary joint.

2.12.5 Antifriction bearing

2.12.6 Main parts in thermal oil system.

2.12.7 Main parts in electrical control system.
