Screen printing machine with pneumatic pistons raising wiper - is for cleaning print and is controlled by solenoid valves in line from air compressor

摘要

The screen printing machine has a compressed-air piston to the right and to the left of the wiper's support. The pistons are connected to a compressor. The pistons lie along the same axes as the support columns that they carry. Solenoid valves set the required position and are located in the line from the compressor. A ring is located at the lower end of each column and is fixed by a screw that has a blind hole open at its bottom. The upper end of an extension to the piston passes into the blind hole and rests against the bottom of the hole.
