A kind of curved surface screen printer of high automation
Technical field
The present invention relates to screen printing device field, more particularly to a kind of curved surface screen printer of high automation.
Background technology
The full name of screen printer is " screen process press ", is the machine of printing word and image, its operation principle is:First will
Printing plate is made in the writings and image to be printed, then by artificial or machine ink or tin cream etc. coated on have on printing plate word and
The place of image, be directly or indirectly transferred to paper or it is other print hold on object, for example, textile panels, metallic plate, plastic cement, leather,
On plank, glass and ceramics, to print out printed matter identical with printing plate.
Existing screen printer can be divided into flat screen printer and curved surface screen printer.Existing curved surface screen printer needs work mostly
The manual workpiece loading and unloading of personnel, not only waste of manpower, and also working efficiency is very low.Thus some full automatic screen printers receive
The favor of more and more enterprises.However, though existing automatic screen-printing machine can realize full-automatic processing, because of the office of its structure
It is sex-limited to cause processing efficiency and precision barely satisfactory, and most of automatic screen-printing machine is processed just for specific workpiece, extension
Property is poor.
