Automatic Can-Crusher

​After understanding all the faults in our design, the following changes were made to the final product:

• The car wiper motor was replaced by a truck wiper motor for gaining higher torque vaules without the use of gear system.

• The alignment of the flywheel was corrected to give it a perfect circular motion.

• The dimensions of the body were altered and made short according to the requirements.

• The piston was removed and replaced as it was heavy for the system. The new part was manufactured from a thick metal pipe by sealing off the head part of the pipe that would crush the can.

• The rod connecting the piston and flywheel was cut short in order to fit the new crusher.

• The distance of the bolt connecting the rod to the flywheel was reduced from the flywheel centre to reduce loss of torque.

• The previous passage of the piston was removed and a cylindrical passage was made using PVC pipe such that the new crusher fitted inside the passage. The cylinder was fastened to the body using tie clips.

• Part of the PVC pipe was cut out from the front so that the can could be placed for crushing.

• The body of the can-crusher was cut and a curved plate was placed in order to drop the cans for crushing.
