Dust removal is a matter that every printing factory attaches great importance to. If the dust removal effect is poor, the probability of rubbing the printing plate will be higher. Over the years, it will have a significant impact on the entire printing progress. Here are ten printing dust removal methods for your reference.
Dust removal method on tape winding paper feeding wheel
Tape dust removal is the process of wrapping double-sided tape or fiber tape around a paper feeding wheel and removing dust through the adhesive tape. This method has the advantages of obvious early dust removal effect and convenient installation. The disadvantage is that after using it for a period of time, more paper scraps will stick to the tape and form hard blocks, pressing the surface paper out of pits, which can easily fall on the cardboard, causing printing paste or white. Therefore, after a period of use, it is necessary to clean the dust on the wheels.
Dust removal method by applying adhesive tape to cardboard
When the #printing plate is stuck by dust, causing the printing to show white, stick the double-sided adhesive to the position where the printing leaks, and then proceed with printing. Dust on the printing plate can be removed with double-sided tape to avoid wiping the plate. The disadvantage is that it may stick to the printing plate or other places.
Direct brush dust removal method
A printing press usually has a row of brushes, but this brush needs to be cleaned and maintained regularly, otherwise it may wear out due to prolonged use, causing the brush to lose its dust removal function. It is recommended to change the row of brushes on the printing machine to double row brushes for better dust removal effect.
Roller brush dust removal method
Generally, it is to add a printing unit with 2 brush rollers installed on it. The speed of the brush is lower than the speed of the equipment, and dust removal is carried out through the speed difference of the brush rotation, but this investment is relatively large.
Water dust removal method
In winter, the first color can be installed as a whole printing plate, and then water can be added to clean the cardboard dust by dipping the printing plate with water, and the cardboard is not easy to burst. The disadvantage is that it is easy to deink after printing with water, and the cleaning time of the screen roller is relatively long.
Equipment cleaning and dust removal method
Many enterprises are very prone to such a problem, which is that the dust in the cardboard box and cardboard workshop is relatively large, and the paper dust can easily fall into the top of the printing machine and the machine baffle, accumulating a lot of dust on the top of the equipment for a long time. Due to the vibration generated when the equipment is turned on, the dust falls into the cardboard or printing plate, causing poor printing. Therefore, it is necessary to clean the equipment in a timely manner to ensure smooth printing.
Ground watering and dust removal method
This method is relatively simple and the easiest to use in daily life. The paper dust generated during the slotting process is easy to fly inside the equipment. If water is sprayed on the equipment ground, the paper dust will not fly again when it falls onto the ground.
Dust removal method using a washing tube
Install a row of vacuum devices on the edge of the brush, passing the vacuum opening through the width of the printing machine. Individual vacuum tubes can also be closed to remove dust by adjusting the suction force.
Paperboard empty running dust removal method
Run the cardboard directly through the printing machine unit while removing dust, and then proceed with printing. The disadvantage is that the cardboard is relatively time-consuming and prone to crushing. Please use it as appropriate.
Dust removal method
Clean the cardboard with a brush and organize it before printing. This method is relatively effective, but it is extremely time-consuming. It is recommended to use it when the quantity of cardboard is small.
