Icing Dispenser

The dispenser runs in a simple mechanism.

We uses the coupling concept* in which the spiral metal rod is being spinned by the help of a motor. This spinning action allows the perspex plate to move down and press the syringe in order to make the icing move out . When the switch is changed, the spiral metal rod will be spinning the opposite way and the lowered perspex plate will be lifted up.

The icing dispenser is at all times clamped on top of the xy table and it does not move in any x and y direction.

* coupling is a system whereby two shafts are connected at their ends for the purpose of transmitting power. In this case, the rotating motor transmits power so that the spiral metal rod can spin.

At first, we encountered a problem as the water drips slowly when we did the testing. This problem has to be overcomed as later we are going to substitute cake icing which is much viscous. Consequently, the drawings on the cake will be defeated as the speed of the xy table and the dispenser does not coincide.

As a solution, we used two pieces of perspex to push down the syringe and finally we are successful. Previously, only a piece of perspex is very light and thus it is unable to push the syringe which the syringe stiffness has to be taken into consideration.
