Description
Technical field
The present invention relates to print field more particularly to a kind of automatic bat printing control methods.
Background technology
Bat printing belong to it is a kind of indirectly can recessed rubber head printing technology, have become various body surfaces printings and decoration at present
A kind of main method.Its technical process is very simple:First the pattern of design is etched in printing flat board, etched plate painting is oiled
Then most of ink therein is transferred on printed object (stock) by ink by silica gel head.
Bat printing has become a kind of main method of various body surface printings and decoration at present, such as when product space compares
Small or structure is more complex to be not easy using traditional printing mode in its surface printing, the use of pad printer is good selection.It moves
Print machine is a kind of printing equipment, and it is suitable in the fields such as plastic cement, toy, glass, metal, Tao Ci, electronics.Bat printing function is small
Area, male and fomale(M&F) product on printed.Therefore there is obviously advantage using pad printer printing.
Pad printer chief component is:Falsework, rubber head printing equipment, ink supply ink-scraping device and control system.It is moving
When print machine prints stock, ink is sprayed on etched plate first, then scalable scraper is scraped extra ink with one
Fall, stays in the solvent being eclipsed in the ink in region and volatilize and form gelatinous surface, then rubber head drops on etched plate, sucts
Ink, and on the substrate by ink printing.
This printing technology effect is exquisite, careful, and is extremely suitable for small area, male and fomale(M&F) etc. other printing processes are difficult to play
The place of effect, therefore pad printer is widely used in electric appliance, plastic cement, toy, Glass lamp industry.Traditional pad printer is driven by cylinder
Mimeograph in template is transferred on stock by single rubber head, in printing process, needs manually to position stock, to printing
Object and the position relationship of rubber head are calibrated, since artificial participation causes the degree of automation not high, and after stock printing
Unstable quality.Not only very time-consuming and laborious, working efficiency reduces, and is also easy to generate a large amount of defect ware, further result in
The wastes of manpower and materials.
