pneumatic paper cup making machine pdf

Generally the cups and plate are made in plastics.The plastics are harmful and it has many disadvantages to us. By naturally we get leaves, Leafs by using this we can make cups. It is very cheap and it does not have any chemical effects. The Paper cup is made by a pneumatic machine. The machine is operated by the pneumatic system. By using this we can produce cup at high production rate. By using different shape die we can produce different shape and size cups. The machine size is comfortable to suit any where.The air enters to the flow control valve and gives pressure to the double acting cylinder. The direction is control by the direction 5/2 control valve. The movement of piston will be varied by adjusting the flow control valve. By adjusting the speed, the production rate will be varied.

“Pneumatic paper cup forming machine” is a wonderful project topic for mechanical engineering students.
In a pneumatic system, energy is stored in a potential state in the form of compressed air. Working energy is produced in a pneumatic system when the compressed air is allowed to expand. So, in order to do work, a device is required which is able to supply an air tank with sufficient amount of air at a desired pressure. This device usually happens to be a positive displacement compressor.
Advantages of using a pneumatic machine:
1) Lower cost than Hydraulic Machines
2) Works on air which is freely available.
3) Compact when compared with Hydraulic Machines
4) Energy can be controlled relatively easily using valves.
The procedure for the development of the paper cup has been broken down into 5 stages
Stages of development:
1) Body Sealing
A Cup fan wall shaped sheet of paper should be first sealed so as to obtain a cone shape.
2) Bottom inserting
Round pieces which serve as the bottom of the cup is inserted into the cone and sealed
3) Bottom knurling
Knurling of the excess portion of the cone is done
4) Rim Curling
Rim curling is done to make the cup end curled.
5) Dispensing
The finished cups are automatically discharged from machine.

Factors to be taken into account while designing the cup:
1) Bottom diameter
2) Top diameter
3) Height
4) Bottom knurling height
5) Side sealing width
Note:
For best results double PE coated paper is used in the development of cups. Since, in one side PU coated paper cups the paper becomes softened and the chances for the beverage to leak out are high.
