Operational Manual

Drive Mechanism

The platen is driven from ball bearing mounted shaft through high speed
double helical gears running in oil bath and protected by guard.
Main gear shaft and connecting arm are mounted on bronze bushes.
The reduction gear shaft is made of hardened high quality steel .Lubricated counter
pressure elements prevent the gears from deviating under the work pressure.

Impression Adjustment

Quick and simple adjustment of impression is made through two eccentric bushes and
the amount of impression can be easily read off on a graduated scale.
A key for impression adjustment is also provided as a tool.
New Worm gear system for impression adjustment is available in all export model
Machines , This system is easy and much user friendly for quick impression
adjustment with a key provided with the machine as service tool. Please must
Loose the lock before moving the eccentric for impression adjustment.

Single/Dwell Timing Device

This timing device can be set to give a variable period from o to 30 seconds .During
this time the moving block i.e. platen remains stationery in the open position before
automatically resuming motion at the end of set dwell period.

Mode of Movement of Platen

The mode of movement of platen can be set in three position through a rotary
switch provided on operation panel:
a) Single impression: In this mode platen will stop after every impression and
will not start again until the operator pushes the clutch on.
b) Dwell timing device: As stated above

Continued Operation 

Platen will move continuously on this mode and stop only when the brake is applied.
A LIMIT SWITCH IS FITTED AT BOTTOM SIDE THE LEVER MUST TOUCH THE LIMIT SWITCH TO ENSURE WORKING OF TIMER

Automatic impression counter:

The impression counter allows an accurate check to be kept on the number of
impressions made by the machine.
A LIMIT SWITCH IS FITTED AT BOTTOM SIDE THE LEVER MUST
TOUCH THE LIMIT SWITCH TO ENSURE WORKING OF COUNTER.

Electro-Magnetic Clutch and brake

Electro- magnetic clutch & brake enables push button control of the machine for
easy and efficient operation. Complete safety is ensured by full electrical interlocking
Electrical synchronization of both clutch & the brake eliminates the possibility of time
lag or over-lag between driving and braking .

ADJUSTMENT OF AIR GAP BETWEEN CLUTCH/BRAKE COIL & CENTRE PLATE

DURING RUN OF MACHINE USER CAN FACE PROBLEM OF INCREASE/DECREASE GAP BETWEEN CLUTCH/ BRAKE COIL AND CENTRE PLATE. THIS GAP SHOULD BE 0.10 MM.THIS GAP CAN BE INCREASED /DECREASEDBY ADJUSTING SCREWS IT IS ADVISABLE TO USE GAUGE TO MEASURE THE GAP REQUIRED. WHEN THE SOUND IS INCREASED WHILE BRAKINGGAP SHOULD BE CHECKED AND ADJUSTED.

Safety :

All moving parts are protected by safety guards. A special feature is the patented
guards which protects operator from the moving block (platen) If any object
come between the moving block (platen) and this guard a slight backward movement
of the guard will occur stopping the moving block (platen) immediately and isolating
the starting mechanism . Until the guard is moved forward by hand the machine
remains dead and isolated from any attempt to actuate it through the starting
mechanism.
LIMIT SWITCH IS FITTED AT THE BOTTOM OF GUARD AND THIS
LIMIT SWITCH MUST TOUCH THE GUARD
Now Days the Hand Brake is Replaced By The Sensors fitted on the Platen ,these sensors
stops the Platen if any object comes in between the Receiver and The Transmitter .
THIS IS AN OPTIONAL ATTACHMENT AND AVAILABLE ONLY ON
REQUEST AT ADDITIONAL COST

Installation

Sujata die cutting creasing embossing press leaves the factory duly packed
in one wooden case. Unload the machine by Crain only therefore a hook is provided
at the top of the machine. Pallet Crain can also be used for un loading.
Machine must be installed on a levelled floor and level must be checked
with level checking instrument. Before giving the current to the main
rotate the main shaft with the help of handle provided with machine as
tool. The power /voltage and cycles must be checked before connecting
the machine to main.
Before giving impression must be sure that the gear key and other parts, bolts
are properly tighten . Don’t increase the impression more than one step once.

Operation of machine by power:

Before giving the main connection to the machine must check that all connection
is properly connected and voltage not less than 380 v Ac 3 phase .After connection
check the three indicator lamps on control panel for 3 phase line, then check the main
pulley is free and if so start the motor and wait for few second and let the motor
move in regular speed. Then keep the rotary switch on s.impression mode and after
that impression is all right, machine can be run on any desired mode as per requirement
of job.
Note ; We offer our all export model machines to be wired for 220 v 3 phase for
Certain countries if the buyer specify his requirement at the time of order ,other
Wise standard wiring of 440 –3 phase will be done
Don’t start the clutch button before starting the machine .Always first start the main motor and then clutch on to move the platen .Brake will be applied when the clutch off push button is pressed or the patent guard /front guard and trip bar is pressed.

DURING THE RUNNING OF MACHINE OWNER CAN FACE
SMALL PROBLEM WHICH CAN BE SOLVED EVEN BY THE
OPERATOR ,

Lubrication

A lubrication pump pump is provided for the centralization of lubrication to all
vital parts. Fill the tank with sufficient oil in tank of S cam situated in front of machine
this place is just below of moving block and s cam must be dipped in oil .
Lubrication pump (S Cam ,Oil Tank below this cam must
be full of oil while running of press)
Oil bath is also provided in double helical gears and always keep these gears
dipped in oil .

Speed:

Impression per hour can be increased to decreased by changing motor pulley
but it is advisable to run the machine note more than 1000to 1500 impression per
hour for small sizes and 600 to 1000 IPH for big sizes
in continued mode for easy handling of jobs and safety .

Sujata Platen die cutting machines are offered in various models and facilities to use it for multiple jobs we categorize the machines in following :

SDC- CUTTING AND CREASING PRESSES: USED FOR CUTTING ,CREASING ,HALF CUTTING, EMBOSSING WORK BY USING DIES ,EMBOSSING BLOCKS ETC.

SDC JUMBO- SERIES REPRESENT BIG SIZE MODELS OF DIE CUTTING FOR CORRUGATING INDUSTRY, DISPLAY INDUSTRY, FORM CUTTING AND OTHER LARGE FORMAT JOBS.

SHF-  SHF SERIES REPRESENTS  ALL DIE CUTTING FUNCITIONS AS WELL ADDITIONALLY HOT FOILING PRESS FOR PRINTING BY USING BLOCKS AND PRINTING FOILS TO MEET THE DEMAND OF FOIL PRINTING ON PAPER, BOARD AND VARIOUS SIMILIAR TO PAPER

SHF PLUS- IS AN TOP MODEL PRESS CAN BE USED FOR NORMAL DIE CUTTING, FOILING AS WELL AS HEATED DIE JOBS. 

HEATED PLATEN MACHINE MEANS THE PLATEN WHERE A HEATER IS PERMANENTY FITTED, IN NORMAL FOILING PRESS AND DIE CUTTING PROCESS HEATER IS CHASE AND ALTERNATELY REMOVABLE WHILE CHANGING JOBS TO DIE CUTTING BUT IN HEATED PLATEN SOLVE THIS ISSUE AND SAME PLATEN HEATING AND COLD PROCESS CAN CONTINUE WITHOUT INTERRUPTION .

WHILE MANUFACTURING THE HEATED PLATEN IT IS IMPORTANT FOR US TO COVER THE DISTANCE PLATEN MOVING WITH NORMAL RULE DIE AND LESS HEIGHT HEATED DIES AND BLOCK TO COVER THE OPTIONS MACHINE ECCENTRIC IS WIDELY OPENED AND MOVE PLUS TO MINUS FREQUENTLY BY OPERATOR TO ADJUST THE GAP BETWEEN RULES DIE AND BLOCKS , IT ACCOMODATE BOTH 23.799 MM RULES AS WELL AS 4 MM HEATED DIES , THIS FEATURES MAKE THIS MACHINE AN USER FREINDLY PRODUCT. THESE MACHINES ALSO SUPPLIED WITH OPEN AND CLOSE DWELL FUNCTION.
