Top ten printing dust removal methods for printing plants
1. Dust removal method on the paper feeding roller wrapped around the tape
Tape dust removal is to wind double-sided tape or fiber tape on the paper feed roller, and remove dust through the adhesiveness of the tape. The advantages of this method are obvious in the early stage of dust removal, and the installation is also more convenient. The disadvantage is that after using it for a period of time, more paper scraps will be stuck on the tape to form a hard block. In severe cases, the facial paper will be pressed out of the pit, and it will easily fall on the cardboard to cause printing paste or whitening. Therefore, the dust on the wheels must be cleaned after a period of use.
2. Adhesive tape on cardboard to remove dust
When the printing plate is stuck by dust, causing the printing to be white, at this time, the double-sided tape is attached to the position of the printing and then the printing is performed. The dust on the printing plate can be removed by double-sided tape, so that it can avoid rubbing the printing plate. The disadvantage is that it may stick to the printing plate or other locations.
Three, straight row brush dust removal method
Printing machines generally have a row of brushes, and the brushes will wear out and the brushes will be crowded with dust due to the long use of time. This brush needs to be cleaned and maintained regularly. If the brush is worn out, the brush has no dust removal function. The height of the brush installation should also be checked regularly. If it is a row of brushes, it can be changed to a double row of brushes for the best dust removal effect.
Four, roller brush dust removal method
Generally, a printing unit is added, and two brush rollers are installed on it. The rotation speed of the brush is lower than the rotation speed of the equipment, and dust is removed through the rotation speed difference of the brush. This investment is relatively large.
Five, water dust removal method
The first color is installed on a whole printing plate, and then water is applied, and the paperboard dust is cleaned by dipping the printing plate with water. This effect is good, suitable for winter, so that the cardboard is not easy to burst, the disadvantage is that the printing is easy to deink after watering, and it takes a long time to clean the anilox roller.
Six, equipment cleaning and dust removal method
Because the dust in the carton and cardboard workshop is relatively large, the paper dust is easy to fall into the top of the printing press and the machine baffle. This is a problem that many companies are prone to. The equipment is not cleaned in time, and a lot of dust has accumulated on the top of the equipment for a long time. Due to vibration when the equipment is turned on, the dust falls on the cardboard or printing plate and causes poor printing. It is very important to clean the equipment.
Seven, ground sprinkling and dust removal method:
The main source of dust on the ground is the slotting unit. The paper dust generated during the slotting process is easy to fly inside the equipment, so water should be sprayed on the equipment floor. In this way, the paper dust will not fly again when it falls on the ground. This is relatively easy to use.
8. Dust-cleaning tube dust removal method
Install a row of vacuum cleaners on the side of the brush, which is similar to a vacuum cleaner, except that the suction port runs through the width of the printer. The dust suction pipe can be closed individually, and dust can be removed by adjusting the suction force.
Nine, cardboard empty running dust removal method
Put the cardboard directly through the printing machine unit while running dry while removing dust, and then print. This method is relatively time-consuming, and the cardboard is easily crushed. Not recommended for use.
10. Dust removal method
This method is the simplest and the most time-consuming, and the effect is relatively good. It is a piece of cardboard that is brushed with a brush, and then printed after finishing. A small amount of cardboard can be used, and a large amount is not extremely time-consuming.
