2. Paper Entry: The paper to be processed enters the interior of the paper shredder through the paper entry port. 3. Cutting Blades: The paper shredder is equipped with multiple sets of high-speed rotating cutting blades inside. Driven by the motor, these blades rotate at high speed to cut the entered paper into small pieces. 4. Paper Shredding: As the paper passes through the cutting blades, it is quickly shredded into small pieces of paper. These pieces of paper are usually unable to be re-combined into the original document, achieving the purpose of protecting information. 5. Paper Ejection: The shredded paper is then ejected through the paper exit port of the paper shredder. 6. Safety Protection: Modern paper shredders also come with safety features such as overheat protection and overload protection to ensure stable machine operation and user safety. Conclusion: Through the above steps, we can see how the paper shredder safely destroys paper documents. Its core principle is to use high-speed rotating cutting blades to shred paper into small pieces that cannot be recovered, thus achieving the purpose of protecting information. At the same time, modern paper shredders also incorporate various safety protection functions to ensure stable machine operation and user safety.
