The screen printing process of glass is based on the principle of screen printing, printing ink onto the surface of the glass, and then using the curing measures of the ink, the printed pattern is firm and durable. The process is as follows: stretching net → sizing → drying → printing → development → drying ↓ flat glass → cutting → edging → cleaning and drying → printing ↓ sintering 1. suitable for printing glass according to user requirements, cutting glass, can be the rule The shape can also be an irregular shape, then it is edge-grinded, then washed, and dried for use. Special care should be taken here that there should be no water marks on the glass surface. 2. Screen selection The screen printing plate for glass printing is the same as the general screen printing plate. The glass screen printing plate is made of synthetic fiber mesh, stainless steel wire mesh and natural fiber mesh. When printing general color materials, the above-mentioned screens can be used, generally using inexpensive synthetic fiber mesh; when used as gold and silver decoration, stainless steel wire mesh cannot be selected. The specifications of the wire mesh are generally 270 to 300 mesh. 3. The selection of the frame is relatively regular, the deformation of the frame is aluminum alloy frame, its size should be larger than the pattern, the specific size should be the outer edge of the pattern should be between 70 ~ 100mm frame, this article will Introduce Shanghai second-hand pneumatic stretching machine.
Pneumatic stretcher: the chuck clamp does not tighten the mesh cloth - adjust the screw above the chuck; replace the rubber pressure strip; the collet expansion and contraction is inconsistent - adjust the flow valve to make the intake air amount consistent; the piston rod is too dusty to clean and lubricate; The oil mister has no oil or dripping oil. Mechanical stretcher: The chuck clamp does not tighten the mesh - adjust the screw above the chuck; replace the rubber pressure strip; the mechanical part is not flexible - you need to clean the gears, racks and guides of the equipment regularly, and add it inside Lubricating oil; whether the pneumatic top net device has oil. The fixed height and volume of the cylinder should be properly adjusted to avoid breaking the mesh with a certain tension.
Daily maintenance method of the stretcher: ensure that the drain filter of each shift must be drained, check the lubrication of the slide rail, check whether there is any foreign matter jam in the machine running range, and clean the surface of the machine.
Qianneng Precision Hydraulic Stretching Machine can make polyester, nylon, stainless steel and other types of screen into high-precision, high-tension screen, especially suitable for solar panels, microelectronics, fine circuit boards, large billboards, glass deep processing and The high-end screen version of the medical equipment and other industries is stretched. The screen version is widely used in the printing of fine wires of PCBs, fine graphics in LCDs, and edge-sealing printing of liquid crystal displays, as well as high-grade nameplates and panels (such as instruments and meters for automobiles and airplanes, dials, panels).
