Screen printing equipment

Technical field

According to the present invention, a screen printing and drying can be performed while a printing material having air permeability, such as a T-shirt, a cloth bag, a cloth piece, a Japanese paper, a float, etc., is attached while being attached. To a printing device.

Background art

Conventionally, the attachment used for the above-mentioned screen printing device is formed of a bay plate, an aluminum plate, and a stainless steel pan plate. However, such a mounting has the following disadvantages.

(1) Solvents or water contained in water-based ink, oil-based ink, etc., adhere to the mounting base when passing through the dryer (solvents that have become gaseous once condensed and adhered to the mounting mat and became liquid Solvents contaminated the printing material set on the mounting base. In addition, when the material to be printed was thin, the ink often passed through the material, adhered to the mounting table, and the ink was often dissolved by the solvent, thereby similarly contaminating the material. Also, since the mounting base is dirty, the printing base material was also contaminated when attaching or removing the printing base material to the mounting base. Furthermore, when the ratio of the ink surface to the printing surface was large and the material to be printed was thin, the failure rate reached 95%, making it impossible to implement.

(2) When printing on the screen, use a set of temporary adhesive to prevent the material to be printed from lifting up due to the adhesive force of the ink. ) Then, with the liquid The resulting solvents adhere to the adhesive and reduce the adhesive strength. In addition, the temporary adhesive was separated from the attachment, so it had to be applied many times.

(3) When performing screen printing, the retained heat of the attachment is transferred to the print plate or ink, so the printed rice is clogged and the print plate must be wiped frequently. . In addition, the ink gradually became harder due to the retained heat, and the color of the printed matter lacked stability due to the change in the port degree of the ink. Therefore, it was necessary to replace the ink many times during the stamping, which required a lot of labor and time. The present invention is intended to eliminate such disadvantages of the prior art, and can efficiently perform printing and drying operations, and can also make the size of the ink surface and the thickness of the printing material thicker. Regardless, an object of the present invention is to provide a screen printing apparatus capable of obtaining beautiful printed matter.
