ABSTRACT:
A two-bar linkage fast elevating apparatus for screen printing machine includes a two-bar linkage system and an eccentric shaft driving system connected to a rear side of a transverse slide base of the screen printing machine. A reduction motor is connected to a lower end of the eccentric shaft driving system to cyclically lift and lower the eccentric shaft driving system. When the eccentric shaft driving system is lifted to elevate the transverse slide base, the two-bar linkage system synchronously moves the transverse slide base backward, so that a heightened and deepened space giving good vision is provided between a printing bed and a lifted screen of the screen printing machine for an operator to safely, conveniently, and accurately check the printing quality.
