**Working Principles of Paper Shredders** A paper shredder mainly consists of an input port, cutting blades, a motor, and a control system. When users put the paper to be destroyed into the input port, the motor drives the cutting blades to rotate at high speed, shredding the paper into small pieces. This process is controlled by the control system to ensure safe, efficient, and stable operation of the machine. The specific working steps are as follows: 1. Paper input: Users put the paper to be destroyed into the input port. 2. Cutting: The motor drives the cutting blades to rotate at high speed, shredding the paper into small pieces. 3. Paper discharge: The shredded paper is discharged through the discharge port. 4. Protection mechanism: Paper shredders usually have safety mechanisms such as overheat protection and overload protection to ensure that the machine can stop working in case of abnormalities and protect the safety of the machine and users. **Types of Paper Shredders** According to different working methods and cutting technologies, paper shredders are mainly divided into the following categories: 1. Manual paper shredders: These rely on manual operation and require users to rotate the cutting blades to cut paper. They are usually small in size, easy to carry, and suitable for use in homes or small offices. 2. Electric paper shredders: These are driven by a motor to cut paper, offering efficient and fast performance. Based on cutting technology, electric paper shredders can be further classified as follows: (1) Strip shredders: Cut paper into strips. (2) Granular shredders: Cut paper into granular form, suitable for situations with high confidentiality requirements. (3) Ultra-quiet shredders: Operate with minimal noise, suitable for situations where a quiet environment is required. (4) Large commercial shredders: Suitable for large companies and institutions, with features like high efficiency and large capacity.
