2.2.1. Baseframe:
The base that supports the entire machine and where the manifold, the pump and
the motor are stored.
2.2.2. Tank:
This is where the hot-melt or other materials are melted; these materials may be in
bulk form or in chunks.
The tank is made of cast aluminium and is coated with Teflon to prevent soot and
crystallisations. It includes a resistance heating system with probe temperature control
(PT-100 or nickel, depending on the temperature control model) from the main control.
2.2.3. Outer Cover:
Prevents accidental access to the inside of the machine as well as possible
operational interferences.
2.2.4. Pumping and Distribution System:
It features the following components:
Manifold:
This manifold distributes the Hot Melt to the hoses and guns. Made of aluminium, it
is assembled inside the bench. It heats up through internal resistors. The manifold
features outlets to connect the hoses and a filter to remove impurities and a regulator.
The regulator controls the unit’s output pressure.
The manifold should not be dismantled; this operation should
only be done if there is an adhesive leak between the tank and
the manifold.
Pump:
The pump is what moves the Hot Melt or other thermal fusible product at a certain
pressure from the pump manifold through the manifold to the hoses and guns.
The pump is located inside the bench and is driven by an alternating current
gearbox. The pump speed is shown on the display located on the front of the control
panel.
Gearbox:
The purpose of the gearbox is to control the pump. It is an alternating current
motor that is controlled by a vector-controlled frequency variator which transmits the
power through a connection to the pump. The motor speed can be manually or
automatically adjusted depending on the ratio required in the main machine. It can not
exceed 100 rpm.
2.2.5. Electrical System:
It is in the electrical box with the exception of the heat resistors and the motors. All
of the control electronics and the power needed to operate the machine are located
here.
