|
| Bearing:
|
Tapered
roller bearing through precision calibration
with high precision and high rigidity. |
| Bearing's
bushing: |
Closed
type, made of high resilient material, through
precision processing. |
| 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. |
