Three Killers of Printing Safety Production!

1 potential safety hazard of bad operation habits

For all security killers, this killer is the most powerful, at the same time its concealment is the highest, and it is the most difficult to defeat the index.

It is reported that more than 90% of the operators did not operate according to the requirements during the operation, which led to the accident.

Plate mounting (rubber blanket mounting)

Habitual operation

Generally, there are many printing plates for rotary machines. Operators are used to hanging plates in two or more groups at the same time to save time and improve work efficiency. At the same time, sheet-fed offset presses also have this phenomenon. In order to speed up the progress, and after the temporary printing, the master also came to help, that is, one person presses the printing plate and one person jogs the switch.

Potential safety hazard

When loading plates (rubber blanket), if two or more people operate at the same time, their attention is slightly distracted, their hands slip or unexpected machine failure occurs, it is easy to involve fingers and cause personal injury.

Preventive measures

(1) The plate loading work can be operated by one person. Gently hold the plate trailing tip and pad with your hand to ensure that the plate is not scratched and the pad is flat.

(2) In case of mistakes or "power connection" during printing, release the hand immediately and do not hold the printing plate. Since it is a punctual car, it will not cause much loss. If it is not handled, it will cause other accidents.

(3) The situation of various models is different. If you really need to push the printing plate by hand, you can rub some talcum powder on the plate to prevent accidents.

Shovel ink

Habitual operation

Due to the need of ink homogenization, operators are used to holding the ink shovel to move back and forth on the ink roller to homogenize ink, add ink or shovel away excess ink on the ink roller.

Potential safety hazard

When the equipment is running at high speed, such operation is a dangerous operation with many accidents. Once the angle pin of the ink shovel is offset or the ink shovel meets the uneven surface of the ink string roller during operation, the ink shovel will be rolled between the main ink string roller and the rubber roller to cause accidents. In some cases, the printing plate or rubber roller will be scratched, in others, the rubber blanket or roller will be damaged, and even personal accidents will be caused due to the busy hands and feet of the ink shovel in an instant.

Preventive measures

(1) First of all, stand firm, concentrate, hold the ink shovel firmly, and avoid looking in all directions.

(2) When it is found that the local ink quantity of the printed matter is not enough and manual ink filling is necessary, the ink shovel in hand must be firmly grasped, and the small ink roller must be lifted, and then the operation can be carried out after the roller is stopped.

(3) When shoveling ink, the ink shovel should be supported by the main ink string roller and conveniently lean against the rubber roller. It should not be suspended. The contact angle between the ink shovel and the ink string roller should not be less than 45.
