A
coating equipment for corrugated
cardboard production includes an electrically driven guide roller, a glue supply mechanism, a
coating roller, an electric push rod, an
air compressor, and a
solenoid valve. It also includes a detection mechanism, a
control circuit, and a glue residue detection mechanism. The upper end of the electric push rod is mounted together with both sides of the
coating roller. The electric push rod is installed in front of the support frames on both sides of a set of electrically driven guide rollers at the rear end. The glue inlets of the two sets of coating rollers are connected to one end of a first
solenoid valve via a valve, a hose connected in series, and the glue supply mechanism includes a glue tank, a glue delivery
pipe, a
pressure switch, and a glue adding
pipe, all mounted together. Each detection mechanism includes a spring and a pressure
resistor, all mounted together. The glue residue detection mechanism includes a glue receiving plate, a linear bearing, a
pressure sensor, and an indicator circuit, all mounted together. The coating method of this corrugated
cardboard coating equipment includes three steps. This invention can simultaneously coat the upper and lower
layers of the core paper interlayer, improving work efficiency and coating quality, and alerting workers when excessive glue drips.
