A kind of automatization silk-screen printing equipment
Technical field
The invention belongs to mechanical field, relate to a kind of silk-screen printing equipment.
Background technology
In the middle of silk screen printing, it is mainly by the screen printing forme saturating ink of areas mesh, non-graphic part mesh
The ultimate principle of strike through is not printed.On screen printing forme one end, ink is poured into, with scraping scraper plate at screen printing forme during printing
On ink position apply certain pressure, move towards the screen printing forme other end simultaneously.Ink in movement by scraper plate from picture and text portion
The mesh divided is expressed on stock.Whole silk-screen printing process mainly includes blowing, gold stamping, printing, cross cutting, rewinding, Mei Gegong
Sequence is separately positioned on different units, and each unit has and individually controls terminal.And during above, each operation
Between linking be necessary to ensure that accurately with coordinating, be just improved the quality of production.In the middle of existing equipment, burn and silk-screen it
Between, it is all directly to use discharging to be connected with the direct of pan feeding, if producing printing shift phenomenon between the two, it is possible to produce each
Air cylinder driven compensates displacement, thus produces the problem mutually pullled, causes processing inaccurate.Meanwhile, need during silk-screen to scrape back and forth
Plate, thus stock needs to pause and alternately transmits, other mechanisms need stop motion at this moment, for conventional screen
The batch (-type) blowing mode of printer, its inefficiency, and easily pullled at a moment started and have influence on running roller
Life-span.
