The main work of the printing factory is printing, which will produce a lot of dust in a large number of printing, which makes the printing factory have to remove dust regularly. In order to ensure the quality of printing, what is the method of dust removal in the printing factory?
Let's take a look at the dust removal method of the printing factory.
1. Dedusting method
This method is simple, time-consuming and effective. It is brushed on the board with a brush, and then used for printing after finishing. You can use less cardboard and spend more time.
2. Cardboard vacuum dedusting method
The cardboard is moved directly through the unit of the press, dust is removed during operation, and then printed. This method is time-consuming and easy to crush cardboard. Not recommended.
3. Dedusting pipeline dedusting
A row of vacuum cleaners is installed on the edge of the brush, similar to a vacuum cleaner, except that the vacuum port runs through the width of the press. The vacuum pipe can be closed separately, and the dust can be removed by adjusting the size of the suction air.
4. Spray water on the ground to remove dust:
The dust on the ground mainly comes from the slot. The paper ash produced in the process of slotting is easy to fly away in the equipment, so water should be sprinkled on the equipment ground. So the dust fell to the ground and couldn't fly again. This is easier to use.
5. Equipment cleaning and dedusting methods
Due to the large amount of dust in the paper box and paperboard workshop, the paper scraps are easy to fall into the top of the printing machine and the machine baffle, which is an easy problem for many enterprises. Do not clean the equipment in time.
A lot of dust accumulated on the top of the device for a long time. When the device is opened, it will vibrate and dust will fall on the cardboard or plate, resulting in poor printing. Cleaning the equipment is very important.
6. Water dedusting
After the installation of the monochromatic plate, add water again, and clean the cardboard by moistening the plate with water. This effect is also suitable for winter, so the cardboard is not easy to burst. The disadvantage is that after printing, the water is easy to deink and the anilox roll is cleaned for a long time.
7. Roller brush dedusting method
Generally, a printing unit is added, on which two brush rollers are installed. The rotating speed of the brush is lower than the rotating speed of the equipment, and the input is relatively large.
8. Direct brush dedusting method
A printing press usually has a row of brushes. These brushes have been used for too long. They are worn and covered with dust. Clean and maintain the brush regularly. If the brush is worn, it has no dust removal function. The installation height of brush should also be checked regularly. For example, one row of brush can be changed to two rows of brush, so that the dust removal effect is good.
Dust removal method of tape to paperboard
When the plate is stuck by dust, the print will be white. At this time, the double-sided adhesive tape will be on the missing part of the print, and then printing. You can use double-sided tape to remove the dust on the plate, so you don't have to wipe the plate. The disadvantage is that it may adhere to the plate or other positions.
10. Dedusting method of the winding belt of the paper feeding wheel
Tape dedusting is to wind double-sided tape or fiber tape on the paper feeding wheel, and dedust through the tape. The method has obvious dedusting effect, good dedusting effect in early stage and convenient installation.
The disadvantage is that after using for a period of time, the tape will stick to the paper to form a hard block, which will seriously dent the paper surface and easily fall on the cardboard to cause the printing paste or white. So after a period of use, dust off the wheels.
