Beneficial effects of the present invention:
null1. the stepping indexing rotary table for numerical control curve printer and mould are mechanism，Connection handle of the prior art is all staight shank，It easily occurs loosening lower for rotation during work by the mould that is connected to of bolt with indexing rotary table，Thus cause twice printing to be housed in mould and upper stock position is difficult to precisely be stabilized in same position，The printing precision causing stock is poor、Printing figure message walks and other problems，The rotating disk connecting portion of the connection handle of the present invention is arranged to frustum，There is certain tapering，The installing hole of indexing rotary table matches also in frustum with the rotating disk connecting portion of connection handle，And use bolt by both fixing locking，During running，Mould is rotating around connection handle，Connection handle can slightly rotate bottom installing hole，Make between connection handle and installing hole more and more tighter along with the growth of working time owing to the rotating disk connecting portion of connection handle has certain tapering.Connection handle of the prior art is staight shank rather than has the connection handle of tapering, its along with the curved surface printing machine working time the longest and increasingly pine, but the connection handle of the present invention then ensure that the high accurancy and precision of printing contraposition along with the growth of curved surface printing machine working time the most increasingly fastens, and the present invention has outstanding feature and prominent progress.
The screw rod of the most existing feed arrangement is all same uniform pitch, but, cup be the most all stacked above with stocks such as bowls together with whole piece transmission, especially when overlap is the tightest, stock separation feeding is extremely difficult by the feed arrangement of prior art, the two or more stock of as easy as rolling off a log generation is sent together and is caused later process to be difficult to smoothly complete, defect rate is high and is easily out of order, the feed arrangement of the present invention arranges the variable-pitch propeller for sub-material feeding of Unequal distance, and its pitch is to being more suitable for greatly high speed sub-material feeding from little.
The most traditional flexography machine technology is all that a start air pressure is opened simultaneously for the high pressure air rifle of auxiliary feeding, power consumption height, not environmentally, and air pressure auxiliary feeding effect is the most bad, the auxiliary feeding air gun of the present invention synchronized to supply gas in the moment of discharging, not only environmental protection and energy saving, and feeding is better, more adapts to high speed transfer.
In the most traditional flexography machine technology, not assisting air gun during discharging, the discharging air gun mating die in unloading station both sides synchronizes air blowing bottom pore at unloading station and plays good assosting effect for balance unloading blanking.
5. the pore of the mould handle of conventional art is general all in centre, and the mould of the present invention offers multiple pore outer edge at the bottom of the mould of end, multiple pores are uniformly arranged the circumference outer of bottom and with mould, air chamber is communicated along moulds, steadily fly material-receiving device for stock and play the effect of key, especially for diameter more than cup highly, the stocks such as bowl, its counterbalance effect becomes apparent from.
6. the mould of conventional art printing is not rotating steel bushing, and the present invention is provided with rotation steel bushing, and has unified rotating diameter and precision makes mould more resistant to mill.
7. conventional art does not has mould synchronization rotating disk, and its station that need to rotate need to connect driving and rotate, it is difficult to synchronize；On the indexing rotary table of the present invention, all moulds are being all synchronous rotary, mould i.e. connects the miniature linear bearing synchronized under rotating disk and secures mould synchronization rotating disk is put spring and more ensure that its precision and ruggedness, and mould uses durable glue to prepare synchronization rotating disk, more durable.
8. the miniature linear bearing under mould tries to get to the heart of a matter synchronous rotary i.e. connects and secures mould synchronous rotary dish is put spring and more ensure that its precision and ruggedness.
