The powder spraying device of PZ4880-01B lithographic offset printing machine is JP-1 electrostatic powder sprayer, which is mainly composed of four parts: hopper, drive motor, high voltage generator and powder spraying control unit. Among them, the high voltage generator is used to produce For the high-voltage electric field that sprays the powder, the high-voltage lead wire is fixed on the outer surface of the bottom of the hopper by an adjustment screw made of nylon rod or ceramic material with better insulation performance. There is a section of the lead wire passing through the adjustment screw fixed at both ends of the hopper On the support frame.
During one use, the powder-spraying device of the machine malfunctioned. After inspection, it was found that there was a scorch mark on the high-voltage wire at a position in the adjusting screw core. So we borrowed the high-voltage wire of the same specification from another offset press and replaced the original adjustment screw. As a result, the high-voltage wire that was just replaced was broken down after the test machine. Later, we analyzed that the adjustment screw may be broken first. Only then, the high-voltage line was also broken, so we replaced the high-voltage line and the adjusting screw at the same time. As a result, we tried the machine again and returned to normal.
