Design and Fabrication of Pneumatic Can Crushing Machine

Abstract

This paper is based on the design and fabricate of a pneumatic can crusher that will reduce to the smallest possible amount of the volume of aluminum cans by 70%. The can crusher is made up of various parts containing parts such as a lever, base frame, can bin, piston cylinder arrangement, chain sprocket mechanism and bearing. The inspiration behind this design came from the wastages in eateries, canteens of big companies where people gather and consume a lot of canned beverages. Thus, it makes sense that there should be an easy way to dispose of used cans properly during large social gatherings. The Can Crushing machine works with the help of pneumatic single acting cylinder. The machine is portable in size, and as such is easily transportable. Most companies find it difficult to dispose of their used cans in hotels and canteens and to create enough storage space that is required. This paper deals with the operations, the design and structural analysis of can crusher. A Can crusher is a device to reduce large material object into a smaller volume. The crusher reduces the size or change the form of waste materials so that they can be disposed off or recycled easily. The Can crushing machine is designed to crush aluminum waste cans by 80%. reduction in volume. It is used primarily to ease transportation of aluminum waste for recycling purposes. The machine is designed to smash an empty can of diameter 65mm and height 120mm to height of between 25mm to 30mm. It uses compressed air for its operations with the following component parts: pneumatic cylinder, solenoid valve, control unit and hoses. The cans are fed into the hopper and the cans travel in an orderly manner through the chute into the crushing chamber. The air compressor through the pneumatic cylinder supplies the required crushing force. The crushed cans drop through the created space into the collection tray below the crushing chamber
