The synchronization of the power of the flexo printing unit, the balance of the ink supply, and the balance of the printing roller have certain requirements in the printing process. Different flexo presses also have different maintenance and maintenance.
The power of the flexo printing machine is transmitted from the main motor to the reduction gear box of each unit, and the color groups are operated synchronously. To make the overprinting of the printed product stable, the gear box should be well maintained. The reducer is one of the key components of the entire printing press. Pay attention to the amount of oil and the temperature of the oil when it is turned on (the oil must be replaced when it is turbid). Do not start the machine at high speed without lubrication to avoid damage. When it is necessary to make a circle to the plate, the circumferential plate-version motor is started so that the planetary out-of-plane frame can produce forward and reverse revolutions, and the speed of the printing roller can be superimposed or overlapped at the synchronous speed, thereby completing the registration requirements in the circumferential direction.
The ink balance is achieved by an anilox roller and a doctor blade. Anilox roller supply is accurate and reliable. There is a ceramic network line roller, the base roller is coated with ceramic, laser engraving. Its precision, surface roughness, shape and position tolerance, hardness and corrosion resistance are all very demanding and expensive, and it is produced by a professional factory. When using this type of anilox roller, special care must be taken to prevent bumping, keep it clean and prevent ink clogging, and clean immediately after printing. The accuracy of the anilox roller is one of the important factors for ensuring the printing quality of the flexographic printing press.
Anilox rollers are precise transfer ink rollers. The amount of ink transferred is determined by the number of network cables per inch. The higher the number of lines, the more the number of network pits and the lower the amount of ink. The smaller the number of network lines, the smaller the number of network pits and the greater the amount of ink. The number of screen lines in the printing process of the anilox roller is reasonable, which is determined by the color requirements of the printing product. Screen screening, screen printing should be selected high number of lines, low ink volume; field printing should be selected low line, large amount of ink.
The squeegee is used to ensure uniform ink supply to the plate. If no scraper is used, the roller is used to transfer the ink, the anilox roller is pressed tightly, and the ink transfer is fast and the speed is slow. Anilox roller with a large difference in the amount of ink, rotating faster and more ink, slow rotation is less. For this purpose, a squeegee is provided on the flexo press. With the squeegee, the amount of ink transferred from the anilox roller to the printing plate is limited to the ink storage volume of the anilox roller. This ensures the balance of the printing plate ink regardless of the speed of the machine. Therefore, there are high requirements for installing scrapers. The scraper should also have a certain degree of elasticity, toughness and strength. The knife edge should be straight and free of burrs and wrinkles. The commonly used steel scraper is 0.15mm or 0.2mm.
Squeegee installation, there are positive and reverse mounting, and now more use of reverse squeegee, and combined into a scraping ink chamber.
The development of China's flexo edition is relatively late, its development speed is slow, and its application level is low. Compared with European and American countries, there is a big gap. However, in recent years, more and more applications have been made in the packaging of milk packages, adhesive labels, cigarette labels, wine labels, toothpaste tubes, and paper boxes. Due to the lack of understanding of flexographic technology and the limitations of objective conditions, people cannot print products that rival those of offset printing.

Tampon, also known as tampon, is a cotton cylinder, mainly by the cotton, man-made fibers or a mixture of these two materials, a diameter of 1 cm to 1.9 cm and other dimensions, with cotton thread at the end ( Pull rope).
The material of the tampon is mainly made of cotton, man-made fibers or both, when the female menstrual cramps can be placed into the vagina to absorb menstrual blood.
