Fig. 5 Glue mechanism
tank the brass nozzle is attached from where the liquid glue exits the glue mechanism
and gets attached to the bundle of the wooden ice cream spoons [6]. Image of glue
mechanism is shown in Fig. 5.
The glue tank consists of a heater which will melt the solid glue and copper pipe
will conduct the heat throughout the tank at the same temperature. The outer body of
the glue tank is made up of stainless steel [6]. An offset of 5 mm is kept between the
nozzle and the heater because if the hot melt glue comes in contact with the heater
then it may damage the heater. The nozzle is made up of brass due to the good heat
conductance property of the brass. The total height of the glue tank is 250 mm and
100 mm internal diameter in which the hot melt glue will be stored. This Heater
which is inside the copper pipe is directly connected with the PLC setup through
which the temperature of the heater is controlled. Holes of 1 mm are generated on
the nozzle through which the glue will exit the tank. The nozzle pipe diameter is of
8 mm. Glue tank has the capacity to store 3 kg of the hot melt glue in it.
