We summarized the common printing a safety hazard:
1, the safe hidden trouble
that bad operating habits
For all the security hidden danger, harm is the
most powerful, the concealment of the at the same time it also is the highest,
overcome index is the most difficult. More than 90% of the operator is due to
the operation is not carried out in accordance with the requirements in the
process of operation that caused the accident. Here we will list some common bad
habits, so that a wake-up call for everyone.
A. plate (rubber cloth) used to
operate: general rotary press plate is more, the operator is used to hang
version of two or more groups at the same time, in order to save time, improve
work efficiency. Sheet-fed offset press plate also have this kind of phenomenon.
Interim plate, in order to speed up the progress, and the teacher is to help,
that is one version, one point switch. Safe hidden trouble, plate (rubber
cloth), if two or more people operate at the same time, a bit not concentrating,
hand skid or unexpected machine problems, it is easy to finger involved, cause
personal injury.
Preventive measures:
(1) version of work by one operator,
with the hand gently knead plate towing pin and gasket, make sure that pages are
not scratch and liner level off, (2) the plate one thousand mistakes or meet
"electricity", hand to loosening, don't hold the plate, will not have much loss,
if hold, will cause other accidents.
(3) the situation is different for all
kinds of machines. If you really need to use hand push plate, can put some
talcum powder on the layout, the prevention of accidents.
2. Spade ink used
to operate, due to the need of distributing, the operator used with ink shovel
movement back and forth on the ink roller, distributing, add ink or shoveled
away excess ink ink roller. Safe hidden trouble, when in high speed operation,
this belongs to the frequent accidents of dangerous operation, once the ink
blade Angle pin offset or operation of the ink shovel met series of ink roller
surface uneven, ink shovel will be involved in the main series of ink roll and
rubber roll and accident, between light scratch plate or rubber roller, or
rolling bad blanket or drum, even in the drawing ink shovel the accidents caused
by the controls in a flash.
Preventive measures:
(1) the first thing to
heel, focused, hold the ink scraper, don't look in all directions.
(2) find
print ink quantity is not enough and must be manually add ink, ink scraper must
hold in the hand, and to raise the little ink roller, after waiting for the
roller stopped again.
(3) to shovel the ink, the ink shovel to, which is
based on the main series of ink roller, conveniently depend on the rubber
roller, an impending, ink scraper with bunch of ink roller contact Angle is not
less than 45 °.
3. In addition to the dirty habits operation: rotary press
and sheet-fed offset printing presses, often appear leather or rubber roller
ink, paper, cast in plate picture and text part of the phenomenon. Affect the
quality of the product. At this point, the operator is often used in the machine
is running to remove dirty fingers.
A safety hazard: this belongs to the
illegal operation of dangerous operations, resulting in the printing of the
accident. Under the condition of the high speed machine operators to get dirty
point location and erasure, available time is quite short, and the strength not
wipe off, only to start early, take strong to stick it on the plate dirty point
on the graphic (or ink roller) removed. A slight mistake, finger are likely to
enter the plate cylinder space. If it is hung up without relying on the
operation, is likely to be brought into the cylinder with one hand, the accident
caused by the rolling hand.
Preventive measures:
(1) a week regular
inspection of the machine all the safety insurance device and main motor brake
mechanism. Make sure the machine sensitive, reliable, and found that the problem
timely repair.
(2) the operation is to focus, not suspended operations, wipe
dirty, palms must rely on between the plate cylinder and rubber drum of the
shaft, or on the water roller protection safety hood, pay special attention to
the palm relying on the force should be greater than the force of finger wipe
dirty point.
(3) if the dirty point much effect on printing, should stop
check and timely replacement of rubber roller or paper, ink, fundamentally solve
the problem. In the daily production, must establish the idea of safety first,
cultivate good habits of operation, or in the event of accident, the product
quality and economic benefit etc. Everything will be impossible. So, bad
operation habits is the biggest killer of safe hidden trouble. (Gold Printing Group)
