Designing a Plastic Shredder Machine (36 Blades) in SolidWorks

Updated: May 6

Plastic Shredder Machine

Plastic pollution is a growing concern worldwide, and recycling plastics is crucial to mitigating its environmental impact. One essential tool in plastic recycling is a shredder machine, which breaks down plastic waste into smaller pieces for easier processing. In this blog post, we'll walk through the process of designing a plastic shredder machine with 36 blades using SolidWorks.


Step 1: Research and Conceptualisation

Before diving into the design, it's essential to research existing shredder designs and understand their key components and functionalities. Additionally, identify the specific requirements for the shredder, such as the types of plastics it will process and its capacity.


Step 2: Initial Sketches and Design Specifications

Based on the research, create initial sketches outlining the basic structure and features of the shredder machine. Define design specifications, including the dimensions, materials, blade configuration, motor power, and safety features.


1. Creating the Base Structure: Start by modelling the base structure of the shredder machine, including the frame, hopper, and chute using SolidWorks' sketching and extrusion tools.

2. Blade Design: Design the shredder blades, considering factors such as blade shape, size, and arrangement. Utilize SolidWorks' features like Revolve and Extrude to create the blade geometry.

3. Assembly: Assemble the individual components, ensuring proper alignment and fit. SolidWorks' Assembly feature allows you to simulate the functionality of the shredder machine by testing the movement and interaction of parts.

4. Motor and Drive System: Integrate the motor and drive system into the design, ensuring compatibility and efficient power transmission to the shredder blades.



Step 4: Analysis and Simulation

Perform stress analysis and simulation studies using SolidWorks Simulation to evaluate the structural integrity and performance of the shredder machine under various loading conditions. Identify potential areas of weakness and make necessary design modifications.


Step 5: Detailing and Documentation

Add details such as fasteners, bearings, safety guards, and labels to the design. Create detailed drawings and documentation, including assembly drawings, part drawings, bill of materials (BOM), and manufacturing specifications.


Step 6: Prototyping and Testing

Once the design is finalized, proceed to prototype the shredder machine using 3D printing or traditional manufacturing methods. Conduct thorough testing to validate the performance, efficiency, and safety of the machine.


Conclusion:

Designing a plastic shredder machine with 36 blades in SolidWorks involves meticulous planning, modeling, analysis, and testing. By following the steps outlined in this blog post, you can create an effective and efficient shredder machine capable of processing plastic waste and contributing to environmental sustainability.
