Description

TECHNICAL FIELD

[0001] The utility model relates to digital printing machinery technical field, concretely relates to a digital printing machinery multicolor ink box quick switching device. BACKGROUND

[0002] With the rapid development of digital printing technology, the demand of multicolor printing is increasing, and the printing machinery needs to frequently switch different color ink box to meet the high-precision and high-efficiency printing requirements. The traditional multicolor ink box switching device mostly adopts manual operation or mechanical fixed structure, and has the problems of low switching efficiency, insufficient positioning accuracy and complicated operation.

[0003] For example, the ink box switching in the prior art usually relies on manual adjustment or single linear driving structure, which causes the ink box carrier to be easily deviated during movement, affecting the printing positioning accuracy. At the same time, the traditional transmission mechanism has a complex structure, a large gear meshing gap, and is prone to transmission error due to vibration, which is difficult to meet the stability requirement of high-speed printing. In addition, the existing ink box mounting groove lacks quick opening and closing design, and the ink box needs to be repeatedly disassembled and fastened during replacement, which increases the downtime and operation complexity.

[0004] Although some improved devices introduce sliding guide rail structure, they do not effectively solve the problems of multi-axis linkage accuracy and vibration suppression, resulting in insufficient stability of the ink box carrier during high-speed movement. For example, single gear drive is adopted for transmission, which is prone to jamming due to uneven load. The positioning mechanism mostly relies on mechanical limit block, which is difficult to achieve precise locking of multiple stations, and lacks deviation mechanism. In addition, the sealing of the ink box mounting groove is insufficient, which is prone to ink evaporation or pollution, and the traditional damping design mostly uses simple rubber pad, which cannot effectively absorb the influence of high-frequency vibration of the printing machine on the switching accuracy.

[0005] In view of the above problems, a multicolor ink box switching device with compact structure, accurate transmission, quick switching and high stability is designed to improve the automation level and production efficiency of digital printing machine, and reduce the maintenance cost and operation difficulty.
