Abstract

The application discloses an industrial printing nozzle diaphragm replacing and cleaning integrated process, adopts a glue thickness control module to control the glue layer thickness to be 0.03-0.1mm; two modes of glue layer transfer printing or glue roller surface tension roll coating can be selected to complete diaphragm gluing; firstly, initial positioning is carried out by using a single glue roller, and then after the single glue roller is removed, secondary accurate positioning is realized by reinstallation; then, special clamps are used to control the pressing pressure, and nozzle diaphragm pressing, curing and solidifying are completed, and the process can be simultaneously applied to diaphragm replacing and nozzle cleaning operations. The application considers two gluing modes, has high positioning precision, uniform and controllable pressing, process standardization, and effectively improves the nozzle maintenance quality and service life.
