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 9 (Semester 2) : continuous project

the body of part A is finish and fitted.

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.

Week 7 (Semester 2) : Project progress

the project is still under process and it may have take time up to 2 or 3 month to finish this project if there no failure during the construction.below are some of the parts and things that will be used in my fyp project

the body of Plastic bottle shredder machine

using power window motor (proton car) and have mounted the motorcycle timing chain sprocket  to the motor

Grass cutter blade is used to mount to the heavy duty single phase induction motor shaft.
the blade is added with strong metal to make the blade hard to bend

body for the mount of the blade

wood grinder blade is used to force the plastic bottle.the grinder blade is  weld to the  iron that will become shaft

Week 6 (Semester 2) : Project construction

after the final drawing have been analyze and agreed by my supervisor, the project is star to be constructed. the item that have been purchased will be fixed to the project. the item like grinder, drill, welding machine are be used to make this project happen

week 5 (semester 2) : Item Purchased

i have bought some item for my final year project. the item will be update soon.because i have to do a little experiment to the item before confirmation to used it
