efficiently

Can Crusher • A can crusher is an instrument used for

crushing soda cans. • This is done to make storage easier.• This provides more space in the bin.• The very first can crusher was the

human foot.• These can crushers are used in the real

world when people or companies that have aluminum cans want to save space in the recycling bin.

Aim of Project

• Understand basic type of motion.• Demonstrate a slider – crank mechanism.• Use computer and software for modeling and

simulation by using solidworks.• Analyze functional relationships.

Kinematic Can Crusher The can crusher employs a slider-crank as it’s a sliding mechanism. This allows the crusher to exert a larger amount of mechanical leverage to the can. The motor drivers the crank-arm which then slides the piston forward via a connecting linkages. After the piston has crushed the can , the discharge door expel the crushed can into a receptacle below.

FORCE REQUIRED TO CRUSH THE CAN

• Procedure:Create an Explicit Dynamics (ANSYS) Analysis System Project Select the units system and define the material properties Import, modify, and mesh the soda can geometry Define analysis settings, boundary conditions, and external loads Initiate the solution (AUTODYN - STR) and review the results

From ANSYS will get information

Force Required = 812 N

Torque, T = F × rT=812 N * 0.130 m = 105.6 N.m

ω = 2*π*7rpm/60 =0.732 rad/swhere, N is speed of the crank.

Power is given by P =T ω

P=105.6 N.m *0.732 rad/s = 77.3 wattMinim of required power at AC Motor is 77.3 watt

It is need increased 15% for safety required power that’s occurs

friction between pipe and piston and loose power at weight of fly

wheel

The safety power 77.3 * 1.15 = 88.89 ≈ 89 watt

Automation Control ( by using Arduino)

•Control on – off by Mobile Bluetooth .•Automatic controls of store Cans. •Auto stopped When empty store•Number of cans crushed

CONCLUSION• The proposed design procedure was being adopted for the fabrication

of automatic can crusher machine which make the product durable for long time as well as make it efficient, also helps to understand the concept of design.

• Thus with the help of this design and electronic component we fabricate automatic can crusher machine to simply reduce the volume of cans as well as to reduce human fatigue.

• The can crusher is providing with photoelectrical sensor that has ability to stop the mechanism when there are no cans in the store.

• When automated the mechanism, it has ability for auto charging cans.

• This mechanism can be used in the future in a factory of can recycling.
