Satellite type Flexo Printing Machine's color separation drying and Bridge drying device. Interchromatic drying is mainly to pre-dry the surface layer of ink after each color printing, so as not to affect the next color printing. After all printing is finished, the final bridge drying device will be thoroughly dried.

In order to reduce the demand for fresh air and reduce the consumption of heating energy, double-loop air circulation is used in the inter-color drying device and bridge drying device. Usually the channel is equipped with a temperature detector rod, when the set temperature, it will be through a cylinder to control the air valve open and close to ensure that the drying channel temperature.

At present, there are many ways to provide thermal energy, such as electric heating, oil heating, steam heating and gas heating. According to different products, UV printing and drying can also be used in conjunction with printing parts.

The cooling of the satellite Flexo Printing Machine mainly refers to the cooling and winding cooling of the central printing roller. The cooling of the central printing roller is mainly to maintain a constant temperature, so as not to affect the printing accuracy and quality. The cooling effect of coiling traction is mainly to cool the finished product after drying and drying. With the natural cooling of the free coil, the next composite process will be affected.

There are mainly 3 forms of control and management system for satellite Flexo Printing Machine.
Quick control system based on manual regulation, electronic information system based on automatic regulation and digital control system based on automatic regulation. The digital control system is composed of seven stepping motors to drive the printing unit. The PC/PLC technology is used to manage and monitor the printing area. The automatic alignment of the axial and circumferential direction and the low speed rotation of the screen roller are realized when the machine stops. The modem provides fault diagnosis for the whole printing machine.
Quick control system based on manual regulation is easy to operate, easy to train and maintain operators, and low threshold for entry. The control system based on automatic regulation has powerful functions, complex structure, various functions, high degree of automation and humanization, and needs high-quality engineers and technicians to maintain and use.

According to statistics, the market share of flexible printing in the United States is 70% in the field of flexible packaging printing, 85% in the field of label printing, 98% in the field of corrugated carton printing and 25% in the field of carton printing. Flexographic printing also accounts for 60%, 35%, 85% and 3% of the market share in Europe. Even 20% of newspapers in the United States are flexographic. This is enough to prove the vitality of flexography, flexography has its own advantages - fast, green and environmental protection as well as the supporting process is relatively fast. In Europe and America, flexography has occupied most of the printing industry. It is understood that some customers in Europe, the United States, Japan require China to export products using a more environmentally friendly printing method. In the United States, flexographic printing has been widely used in various printing fields, especially in the field of packaging printing, flexographic printing occupies a very large proportion. Satellite flexography will be the mainstream of the printing industry in the future.
