Description

Biaxial ink jet printing equipment and control method Technical Field The invention belongs to the technical field of cylinder ink-jet printers, and particularly relates to a double-shaft ink-jet printing device and a control method. Background The cylinder ink jet printing technology is widely applied to surface pattern decoration of various cylindrical products, such as beverage cans, packaging bottles, tubular containers, industrial parts and the like. Existing cylindrical inkjet printers typically employ a single axis design with a printing mechanism that mates with a single rotating carrier shaft. When the printing operation is carried out, firstly, the clamping of the blank is required to be completed manually or automatically on the bearing shaft, then the equipment starts a printing program, and the inkjet printing mechanism is used for completing the inkjet printing of the surface pattern in the rotating process of the blank. After printing is completed, the apparatus must be shut down, and after waiting for the printed stock to be removed and replaced with a new stock, the next printing cycle can begin. This single axis mode of operation presents a significant efficiency bottleneck. Since the loading and unloading operation must be performed in a state where the equipment is completely stopped, the printing process and the loading and unloading process cannot overlap in time, and a discontinuous workflow which is alternately performed is formed. In the whole working period, the effective time occupied by the device for printing is relatively low, and a large amount of time is consumed in the non-productive loading and unloading links. Especially for mass production, the frequent start and stop not only reduces the utilization rate of equipment and the output in unit time, but also increases the labor intensity and the auxiliary time of operators. Therefore, the existing single-axis cylindrical inkjet printers have obvious defects in pursuing efficient and continuous automatic production.
