2.1 MECHANICAL CHARACTERISTICS
The HS2510-N Hot Melt Applicator is designed to apply to general types or
shape of hot melt adhesive with viscosities ranging from 1,000 to 100,000 cps,
suitable for manual, semi – auto, and automatic application.
The applicator includes two major parts, electrical control system and hydraulic
system.
The way to keep temperature is wrapping the bottom and ambiance of melting
tank with double isolation fiber, reducing heat been absorbed by surface of the
machine and avoid operator being burnt.
The solid adhesive is melted in the special-treated tank, flow to the bottom of the
tank, and gathering around the and gathering around the gears pump.
While the motor stars to drive the gears, the molten material will be absorbed
into the gear pump and in the mean while extruded via the heating plate to the
manifold, and the filter assembly, then guide through the hose to the dispensing
nozzle or gun unit, and deliver the ADHESIVE to the substrate.
The hot melt tank, heating hose and the dispensing nozzle for automatic
application are all controlled by individual temperature controller separately.
The hot melt tank is controlled by P.I.D. temperature controller, and the heating
device are controller by electrical temperature controller. The temperature sensor is
<(K) CA> type.
In this application, also install the mechanical temperature controller, the main
function of this controller is to shut-down the heating power when the heating
temperature is beyond the setting value, due to P.I.D. controller out of function, so to
stop heating and avoid the heating system of tank being burnt .
To prevent the damage of the gear pump or hydraulic system due to over
pressure inside the hydraulic system, the manifold has the pressure relief valve, to
adjust the hydraulic pressure which comes from the gear pump.
This device is also able to modify the quantity of the hot melt outlet.
