Week 13 (Semester 2): Finishing

the final look of my project is shown below.




full body with mounting of induction motor and shredder blade


the pusher is made to push the bottle to the blade


shredder blade is made by metal


the function of the pusher to push the plastic bottle 


after finishing constructed the machine, the result have been taken.



Result
the result of the plastic bottle shredder machine is shown as above.the plastic bottle is shred into a small part compare to the normal size of the plastic bottle. as we can see, the bottle also be squashed to flat and some of the plastic bottle part is shred.

Week 12 (Semester 2): Final prototype

the final method is constructed and been adjust for the best result. this are some of the works or result of construction of this machine :



the heavy duty induction motor will drive the metal blade by using wheel and axle method and timing belt. 



this roller is used to rotate the blade inside the box to crush the plastic bottle.


bearing is used to give the smoothest rotation to the blade.

Week 11 (Semester 2) : New method

new method by using titanium rotation blade
the design of new blade


after the failure, i have to make a lot of changes to this machine to make it works. the  new method have been found to shred the plastic bottle. by using the rotation blade produces using titanium will make the plastic bottle can cut into small pieces. to make this blade function it will take a lot of time because too much procedure have to take in action to avoid another failure

Week 10 (Semester 2) : Failure

the final part is mount to the project and be tested.





this kind of method have bring failure to this machine. the plastic bottle cannot be shred by using this method due to the hardness of the plastic bottle itself. as we know, plastic bottle are organic polymeric materials consisting of giant organic molecules. so it hard to cut or shred the plastic bottle due to his physical condition. the task was failed because when the grass cutter blade hit the plastic bottle to cut it, the grass cutter blade cannot cut the plastic bottle and the force given by the induction motor make the grass cutter blade force itself to cut it and at last the grass cutter blade is crooked and hit the body of part A and everything is disintegrate. the result of this kind of method is a failure.




the blade hit the body of Part A and crooked.after the failure the blade cannot be used anymore

Week 8 (Semester 2) : Project drawing

Project Drawing (Side look)



i will explain the process of this machine. This plastic bottle shredder machine is used to shred the plastic bottle into tiny part. this is my idea how to build the project. the body with blade will force the plastic bottle to go down slowly and at the end of the part A the bottle will be cut with the grass cutter blade in part B with the speed of 1500rpm. but to make the position of part A and B in center is very difficult because it will take a lot of time and a good measurement without 0 error to make that thing precise.
