Description
Technical field
The present invention relates to silk-screen printing field, and in particular to a kind of screen printer of low-temperature setting.
Background technology
Screen printer, also known as screen process press, it is the machine that print is applied with screen printing forme, belongs to one kind of printing machine.Screen printing
Brush machine is the machine of printing word and image, is for producing the machine of printed matter or the general name of equipment.Screen process press belongs to
More representational printing equipment in porous printer, the material of silk screen is made in addition to silk, also can use nylon yarn, copper wire, steel
Silk or stainless steel wire etc..
Need to solidify ink after silk-screen, existing screen printer is not often equipped with integral solidification equipment, and workpiece leads to
It is typically often that after being unloaded from screen printer, the work that the external curing apparatus such as baking oven solidified is sent to by belt or carrying roller
Sequence, cause production efficiency not high.
Secondly, existing curing mode have dry, the mode such as far infrared electro-thermal tube hot-air seasoning, oven for drying.Naturally dry in the air
Longer during drying loss, infrared electric heating tube or oven for drying are because temperature is higher, high energy consumption and security is inadequate.
Again, for the printing of cylindrical parts workpiece side wall, automaticity is not high at present, toward contact by the way of artificial
Feeding is carried out, so needing the feed device specifically for such workpiece badly to improve the production efficiency of silk-screen.
The content of the invention
