High-speed gravure printing machine printing structure:
Unwinding section: shaftless loading, can adapt to different paper cores, fast replacement, high-speed non-stop material change, save time, improve efficiency, change rolls with zero speed difference, stable tension and low scrap rate.
Drying section: The secondary return air adopts energy-saving, single-group automatic constant temperature control, which is beneficial to printing of various colors. High wind speed and high flow can create a drying method with low temperature and high wind speed. The negative pressure design in the whole box prevents hot air from flowing out.
Cooling part: The cooling effect is obvious, the self-overflow type is used for backflow, no large water pressure, no rotary joint, large wrapping angle of the water-cooled roller, long contact material, obvious cooling effect, flexible operation of rolling bearing, and convenient maintenance.
Frame and feeding section: the secondary internal stress of the overall wall panel is eliminated, high stability, imported machining center processing, high precision, first processing of positioning holes, to ensure accurate positioning of each group, smooth layout of guide rollers, so that the coil runs smooth.
Printing Department: The shaftless plate can be quickly replaced, and the positioning is accurate. The initial plate registration system can quickly enter the register printing, and the three-directional squeegee adjustment can create the best squeegee position angle.
Rewinding section: shaftless coil loading, quick replacement, high-speed non-stop coil change, saving time, improving efficiency, zero-speed difference coil changing, stable tension, low scrap rate, consistent inner and outer winding tightness, no vegetable core phenomenon.
What is the method of dust removal in the production workshop of Rotogravure Printing Machine
1. Dust removal method for computer control high speed rotogravure printing machine tape feed roller: tape dust removal is to wrap double-sided tape or fiber tape around the paper feed roller, and remove dust through the stickiness of the tape. This method has the advantages of obvious dust removal effect in the early stage and convenient installation. The disadvantage is that after a period of use, more paper scraps will stick to the tape to form a hard block. In severe cases, the surface paper will be pressed out of the pit, and it will easily fall on the cardboard to cause printing paste or dewdrops. Therefore, after a period of use, the dust on the wheels must be cleaned.
2. Dust removal method of sticking tape on the cardboard: When the printing plate is stuck by dust and the printing blank is caused, at this time, stick the double-sided tape to the printing blank position, and then print. The dust on the printing plate can be removed with double-sided tape, which can avoid wiping the printing plate. The disadvantage is that it may stick to the printing plate or other places.
3. In-line brush dust removal method: general printing machines have a row of brushes. Due to long-term use, the hair on the brush will wear down and the brush will be covered with dust. This brush should be cleaned and maintained regularly. If the brush is worn out, it will not have the dust removal function. The installation height of the brush should also be checked regularly. If it is a row of brushes, it can be replaced with a double row of brushes, so that the dust removal effect is better.
4. Remove dust with water: install a whole printing plate of the first color, then add water, soak the printing plate with water to clean the cardboard dust. This effect is not bad, and it is suitable for winter, so the cardboard is not easy to burst. The disadvantage is that it is easy to deink after printing with water, and it takes a long time to clean the anilox roller.
5. Equipment cleaning and dust removal methods: Due to the large dust in carton and cardboard workshops, paper dust is easy to fall into the top of the printing machine and the machine baffle, which is a problem that many companies are prone to. If the equipment is not cleaned in time, a large amount of dust will accumulate on the top of the equipment for a long time. Because the equipment will vibrate when it is turned on, dust will fall on the cardboard or printing plate, resulting in poor printing. Clean equipment is very important.
6. Groundwater dust removal method: The dust on the ground mainly comes from the slotting unit, and the paper scraps generated during the slotting process are easy to fly into the interior of the equipment, so the ground of the equipment should be sprinkled with water. In this way, the confetti falls to the ground and will not fly again. It's easy to use.
7. Dust removal pipe dust removal method: Install a row of dust collection devices on the edge of the brush, similar to a vacuum cleaner, except that the dust collection port runs through the width of the printer. The suction pipe can be closed separately, and the dust removal can be carried out by adjusting the suction power.
8. Elimination and dust removal method: This method is very simple, not time-consuming, and the effect is better. That is to brush a piece of cardboard with a brush, arrange it and then print it. Small amounts of cardboard can be used, but large quantities are not terribly time-consuming.
Computer Control High Speed Rotogravure Printing Machine's Ink Must-Have Requirements
During gravure printing, the surface of the cylinder is coated with ink as it rotates. At the same time, the scraper scrapes off the ink in the non-graphic part of the layout, leaving only the ink in the graphic part, and then the ink in the graphic part is immediately transferred to the plastic film by pressing. Gravure inks must have special requirements to meet the needs of printing practice.
From the perspective of the whole printing process, the gravure printing ink of Computer Control High Speed Rotogravure Printing Machine must have the following characteristics:
① Good fluidity, easy to fill the mesh of the plate cylinder;
②It has good scraper adaptability, that is, the scraper is easy to scrape off the ink on the non-graphic part of the rolling surface of the printing plate;
③ There must be sufficient cohesion;
④ It should have good transferability, superimposition and viscoelasticity, that is, the ink in the mesh of the printing plate cylinder is easy to transfer to the film, and it is easy to superimpose on the ink of the previous color. Images, texts, lines, dots Not easy to disperse and become larger;
⑤Has good leveling property, ensuring smooth ink film can be formed after transferring to the film;
⑥ The drying performance is suitable, and the drying speed should be compatible with the printing speed;
⑦It has a certain resolvability to ensure that the untransferred ink in the mesh can be redissolved into the ink system.
In addition, according to different post-processing conditions and product use conditions, the ink performance of Computer Control High Speed Rotogravure Printing Machine must be able to meet and adapt to the corresponding requirements.
