Design and Fabrication of Plastic Bottle Crusher Machine

Abstract
In this project I am going to make this fully automatic by using electronics equipment like sensors, microcontroller, IC’s etc. along with mechanical components due to which crushed cans or bottles are need not to segregate from bin and also machine will not run idle. After all process has been done, this crusher may help us to understand the fabrication and designing process as well as electronics equipment that involved in this project. After the design has complete, it was transformed to its real product where the design is used for guideline.

Crushers are major size reduction equipment used in mechanical and allied industries which crushes different types of soft and hard materials. The can or bottle crusher machine is widely used in beverage industries or in scrap dealers shop to reduce the volume of the cans/bottles. Hence in this design and analysis of various parts are necessary. The Electric Motor and a microcontroller make up the backbone for this project. Overall, this project involves processes like design, fabrication and assembling procedures. This project is mainly about generating a new concept of can/bottle crusher that would make easier to bring anywhere and easier to crush the can or bottle.

Introduction
A can crusher can be defined as “A device used for crushing aluminum cans or plastic bottle for easier storage in recycling bins thereby giving you extra space by flattening of cans”. This project consists of designing and fabrication of an automatic can/bottle crusher machine. In order to reduce the waste, we planned to create a can/bottle crusher that will reduce the volume of aluminum cans/plastic bottles by approximately seventy percent by which transportation volume will increase and transportation cost will reduce. Can crushers are primarily used to save space and for recycling.

Also the purpose of this project is to understand the fundamental knowledge of design and mechanism by using fulcrum system and a simple mechanism property. A mechanical can/bottle crusher machine is basically one of the most aid able machines. It helps to reduce the pollution of the environment. Thus helps to create a better place to live in, apart from that, this can/bottle crusher can actually be the future mode of recycles apart from the recycle bins. It can be placed everywhere, in the park, houses, restaurants, malls, canteens even in cars. Using a similar type of a design from the diagram below, but with an added bin below the can crusher concept of recycling can be applied. In this project, development of a recycle bin can/bottle crusher so the cans might crush as flat and look as symmetrically as possible and inserted the bin. The designs are an environment friendly and use simple mechanism properties.

The design is so done that the knowledge of designing, mechanism and forces. The study of manufacturing was very important in order to carry out this project to ensure that what are needs to do. This project is about designing and fabricating the Recycle Bin Can/Bottle Crusher Machine to help people easy to crush the can as well as bottle and bring anywhere.

This project involves the process of designing the different parts of this crusher machine considering forces and ergonomic factor for people to use. After the design has completed, it was transformed to its real product where the design is used for guideline. This project is mainly about generating a new concept of can/bottle crusher that would make easier to bring anywhere and easier to crush the can or bottle. This machine is developed solely for the purpose of recycling as plastic bottles are harmful to environment and aluminum to plants growth.

Many people recycles items like paper, glass, and aluminum, While these efforts are a vital part of the process, the true recycling path continues long after recyclables are collected from household bins or community drop-off centers etc. Collecting, processing, manufacturing, and purchasing recycled products create a closed circle or loop that ensures the value of recycling. Recycling is a series of activities that includes the collection of used, reused, or unused items that would otherwise be considered waste, sorting and processing the recyclable products into raw materials, and remanufacturing the recycled raw materials into new products.

Concept
This machine is basically works on the principle of Single Slider Crank Mechanism which is the heart of this machine and it converts rotary motion into a reciprocating machine to crush the Cans/Plastic bottles. In this, link 1 is fixed and link 2 which is a crank is rotating about fixed link 1 and converts this rotary motion into the reciprocating motion of slider (corresponds to the link 4) by means of connecting rod which corresponds to the link 3. This is the inversion of single slider crank which is obtained by fixing link 1.

Working Principle

In this, as the motor rotates the motor is having a smaller pulley connected to its shaft, the smaller pulley through the v-belt is connected to secondary pulley (Larger pulley) on another shaft which rotates it. Another i.e. third pulley (Smaller pulley) is mounted on the same shaft next to the secondary pulley, and is connected to the fourth pulley (Larger pulley) which is on the main shaft by means of v-belt. This arrangement has been done solely for the purpose of reduction of speed. Except that there also automation has been done, such as there I have placed a sensor until and unless sensor senses the obstacle (i.e. a Can/ Plastic bottle) the machine will not start.

After machine gets started the power of electric motor is transmitted to the slider mechanism through belt and pulley arrangement and rotary motion of crank is converted into the reciprocating motion of slider thus Cans/Plastic bottles will get crushed. There is a separating bin which is placed beneath a crushing tray to collect the crushed cans/ Plastic bottles also there is a sensor of metal detector type to store the plastic bottles and cans separately.

CONCLUSION
From the above study, it is observed that by arranging different mechanical components along with electronic components machine can be made automatic one to crush the Cans as well as plastic bottles solely to reduce the volume. Thus human efforts can be reduced as well as time also, because sorting system is installed there to separate the bottles and cans to reduce the human fatigue. As above results shows that the volume can be reduced to a large extent i.e. near about seventy percent volume can easily be reduced, thus transportation volume can be increased and transportation cost can be reduced to a large extent and these can be reuse.
