3. Central Bar:
Size =12mm
The Cotton Plug Machine consists of a central bar made of iron having 12 mm thickness which connects the two parallel gear wheels.
4. Front Gears:
Gear size =2.5cm in radius (diameter = 5cm)
A pair of gear wheels are situated at both the ends of the central bar parallel to each other. These gears are grooved and are attached to a pair of rear gears. The front gears and rear gears are attached to each other in such a way that the entire machine works on a single 9 V DC battery at a constant speed.

5. Adjacent Rear Gears:
Gear size = 2.5mm in radius (diameter = 5mm)
These are a pair of rear gears situated adjacent to the pair of front gears. The grooves of these rear gears are fitted into the groves of the front gears which are in turn connected to the central bar. These rear gears are connected to a 9 V DC battery. The rotation of the rear gears sets into motion the front gears and they in turn rotate the central bar.
6. Thread:
A thick cotton thread is attached to the front gears. With the rotation of the front gear, the thread rotates on its axis due to centrifugal force.
7. Cotton Plug:
Size = Cotton plug size as per the requirement. A layer of cotton sheet is placed on an iron sheet touching the tied thread between two wheels in such a way that when thread rotates, the fibers/threads of cotton get entangled by the tied thread. Due to this the cotton sheet gets wrapped around itself and a cotton plug is formed.
8. Height gauge:
Adjustable corks are placed just below the iron sheet for adjusting the distance between the iron sheet and the thread tied. So it is useful for making cotton plugs of different diameters used in different types of tubes and flasks of different diameters.
9. Lifting plate:
Lifting plate is placed there for lifting purpose. It is fitted through height gauge. Iron Sheets are fitted for keeping cotton sheet for wrapping as a base for it. It is fixed at one end and free from another end for adjusting it up and down. It is made

adjustable for making cotton plugs of different sizes for test tubes of different diameters.
10. Thread Locking Nuts:
Thread locking nuts are used for keeping the thread at a fixed place while the machine works. Two thread locking nuts are used in this machine. Each placed besides the gears."
11. Infra blue tube:
Infra blue light which gets emitted from this infra blue tube destroys the germs and kills bacteria which are present in cotton as well as in the moisture.
12. Industrial blanket:

18. Legs:
Legs are made to support the machine and to place it down. The machine is mounted on the legs. The whole weight of machine is centered upon them.
Back-Machine Setup
19. Pulleys:
One pulley is placed on central bar, on one side just beside adjacent grooved wheel and the other pulley is placed just parallel to the previous pulley in a distance close to that pulley.
20. V-belt:
V-belt is mounted on two pulleys. As pulley rotates V-belt rotates.
21. Gear-1:
The gear-1 attached to the pulley rotates. As pulley rotates, gear also rotates.
22. Gear-2:
As gear-1 rotates, the gear-2 attached to it in interlocked manner rotates because of it.
23. Roller-1:
A roller is placed attached to gear-2. As gear-2 rotates, the roller also rotates.
24. Roller-2:
Another roller is placed on the opposite side of roller,-1, maintaining a long distance.

25. Conveyer-Belt:
Between roller-1 and roller-2, a conveyer belt is placed which rotates between the two rollers. It carries the cotton from one end to the other and the process is carried out on it from bulk-cotton into cotton -sheet.
26. Cotton-Sheet:
After getting pressed with casting roller the cotton bulk gets pressed and cotton -sheet is formed.
27. Casting-Roller:
A Casting-roller is placed just above the conveyer belt to make the coming bulk-cotton coming from store-box of the machine into cotton-sheet.
28. Store-Box:
Store-box is made just on the conveyer belt before casting-roller. The coming cotton is stored in it and slowly gets pressed through it.
The top of the box is made of glass material to make it transparent to keep notice on the quantity of cotton stored. If the box gets full, the machine should be stopped for some time.
29. Cotton-bulk:
After plucked cotton from the plant getting processed in blade-shaft chamber, a cotton-bulk (without seeds) is formed which later on gets processed into cotton-sheet.
30. Blade-Shaft Chamber:
In this chamber, from the plant cotton is plucked. As it is directly plucked from the plants it has seeds in it. So, this plucked cotton is put into this chamber. In it the seeds gets removed and is separated out from the cotton and the purified cotton is passed to the conveyer belt.

31. Cultivation-blade shaft:
This cultivation blade shaft is a part of blade shaft chamber. It is fitted inside the chamber.
There are two cultivation-blade shafts which rotate continuously to separate out cotton seeds from cotton bulk. The two cultivation-blades rotate continuously.
32. Plucked cotton:
The cotton is plucked from the plant i.e. cotton with seeds are put in blade shaft chamber as a raw materials. This plucked cotton is processed and seeds are separated from the cotton. Then that processed cotton is pushed into conveyer-belt.
33. AC-Motor Unit:
AC-motor of 3/4 H.P. is fitted on one side of the blade-shaft chamber. It is fitted outside the chamber.
This motor is placed with both the sides pulleys attached to it and bearings are placed parallel to it on both the sides on which the two small belts rotates on both the sides. The two blade-shafts rotates because of this motor set-up.
34. Door of chamber:
A door is there in the blade-shaft chamber to put raw materials i.e. plucked cotton balls in it and cleaning of chamber is also done by opening the door.
(ii) Features of the cotton plug machine.
1. The total dimension of the is 12.5" x 13.5".
2. The machine uses 240 V AC supply for operating the infra blue light.

3. The capacity of the 9 V motor used in the machine is 380 R.P.M.
4. The size and dimensions mentioned above are in respect of machine having capacity for making one cotton plug. The size and dimensions will differ accordingly depending upon the capacity of the machine to produce cotton plugs.
iii) Detailed description of the working of the Cotton Plug Machine:
1. For operating the cotton plug machine raw plucked cotton is loaded into the cultivation blade shaft chamber for separating the cotton from its seeds.
2. The separated cotton then moves ahead on the conveyer belt from the opening of the blade shaft chamber.
3. The cotton thereafter passes through the store box where excess cotton is separated and only the required quantity of cotton gradually moves forward on the conveyor belt.
4. The cotton thereafter passes through the casting roller which presses the cotton into a uniform sheet.
5. The cotton sheet thereafter enters the front machine set up and touches the rotating thread from its base and due to the rotation of the thread due to centrifugal force the cotton sheet rotates around the thread and forms into a cotton plug. The entire machine works smoothly because of the unique interlocking assembly of the gears in the front and back machine setup. During the process, the infra blue light falls on the cotton plug and the cotton plug is medicated.

Thereafter, the cutters attached at both the ends of the cotton thread cut the cotton plug from the rotating thread and the plug so formed rests on the industrial blanket which is pasted upon the lifting plate. The medicated cotton plug so formed can thereafter be put to various uses in the field of life science research, laboratory and for various other research purposes.
