Planetary printing machine

Abstract

The invention discloses a planetary printing machine. The planetary printing machine comprises a first printing roller, a main drive shaft and a second printing roller which are arranged on a machineframe. The main drive shaft is arranged between the first printing roller and the second printing roller. A main drive gear is installed at one end of the main drive shaft and is further engaged witha first gear on the first printing roller and a second gear on the second printing roller at the same time so as to drive the first printing roller and the second printing roller. The main drive shaftis driven by a servo motor. The first printing roller and the second printing roller are provided with two sets of printing color units in a matched mode correspondingly. A compression roller is further arranged at the feeding side above the second printing roller and can further adjust the pressure for pressing printed objects onto the second printing roller by the compression roller through anair cylinder installed on the machine frame. Drying devices are further arranged between the first printing roller and the second printing roller. The first gear and the second gear are engaged with anilox roller gears of the printing color units matched with the first gear and the second gear separately. The planetary printing machine has the advantages of being simple in transmission structure,low in manufacturing and productive maintenance difficulty, good in printed product quality, high in production efficiency and capable of achieving linkage easily.

Description

technical field [0001] The invention relates to the technical field of plastic woven cloth printing and processing equipment, in particular to a planetary printing machine. Background technique [0002] The flexographic printing machines of the existing technology are divided into stacked type, satellite type and unit type according to the structure. After years of development and use, these types have the following shortcomings. For the stacked type, the disadvantages are complex transmission, gear gap points There are many color groups, the combination of color groups is difficult, the overprinting accuracy is poor, and the connection is difficult, so it can only be used for general printed matter; the disadvantage of the satellite type is that the cost of the machine is high, the number of color groups is limited by the size of the central cylinder, and the arrangement of each color group Different angles make it difficult to add color groups; secondly, the post-press pro...

[0002] The flexographic printing machines of the existing technology are divided into stacked type, satellite type and unit type according to the structure. After years of development and use, these types have the following shortcomings. For the stacked type, the disadvantages are complex transmission, gear gap points There are many color groups, the combination of color groups is difficult, the overprinting accuracy is poor, and the connection is difficult, so it can only be used for general printed matter; the disadvantage of the satellite type is that the cost of the machine is high, the number of color groups is limited by the size of the central cylinder, and the arrangement of each color group Different angles make it difficult to add color groups; secondly, the post-press processing process is difficult to connect online, the distance between each printing unit is too short, the ink is not dry and easy to smear; the disadvantage of the unit type is that it occupies a large area and the paper feeding line is long.
