Oil Heating Test Roll

Detail Information

Description :

MODEL : CW-206 , CW-208 Appliation Of Test Roll To Plastic Processing:
1.The Test Roll can be used to test the following plastic materials and their related agents:
-PVC(Polyvinyl Chloride): Rigid PVC, Non-Rigid PVC
-PP(Polypropylene)
-PS(Polystyrene)
-ABS(Aerylonitrile-Butadiene-Styrene Copolymer)
-EVA(Ethylene-Vinyl Acetate Copolymer)
2.The stabilizer can use the Test Roll to do Milling Test and also can be added with TiO2(Titanium Dioxide) to be mixed together and then works with the Aging Tester to do Static Stability Test.

Bearing lubrication:

Adopt high temperature-resistant grease lubrication. Easy
maintenance.

3. NIP ADJUSTMENT

The two sides of the front roll are each installed with one precise micro regulator with a graduated ring. The gap between rolls can be easily adjusted by the hand
wheel so that the precision and stability of testing plastic sheet¡¦s thickness can
be achieved.

4. DRIVING SYSTEM

The front/back rolls can be individually infinitely various speed. Range of various
speed: 8 r.p.m ~ 28 r.p.m. The driving system consists of two high torsion motors,
one high precision infinitely variable speed inverter and one high torsion precision gear box. The correct rotating speed ( r.p.m.) of rolls can clearly show on the two
tachometers.

5. OIL HEATING SYSTEM

The heating oil circulates in the drilled roll to make the roll’s surface temperature
accuracy reach +/- 1oC. The main functions and merits of the oil heating precision temperature control system as follows

»	Keep constant high temperature/high stability: Roll’s surface temperature accuracy keeps at +/- 1oC and can¡¦t be changed under long-term use. High hot efficiency.
»	High temperature/low pressure system: Temperature goes from 60oC to 250oC and can be freely set as per the used temperature. Hot oil delivering pressure in the pipe is only 0.5 - 4 kg/cm2. Closed system design, low pressure design, high safety.
»	Simple & safe operation: Fully automatic operation, multi-safety protection control system, high safety,high efficiency.
»	Save energy and cost: Closed system design, hot oil to be circulated in the closed system, energy & cost saving

6. SAFETY DEVICE

The front/back sides(red positions) of machine base under the rolls are equipped with knee-push safety brake system that is pushed by the knee.

7. CONTROL SYSTEM

Temperature control:
Use P.I.D. digital controller that features high precision and multi-function
and in 96mm x 96mm. Plus multi-protection system, temperature stability
and accuracy can be surely controlled.

8. OPERATING CONTROL

Temperature controller, tachometer, push-button, alarm lamp, volt meter, ampere
meter are all centralized on the control panel for easy operation and control.
