1. 供电与启动：当用户按下碎纸机的电源开关后，机器内部的电机开始工作。 2. 切削刀片：电机驱动一组锋利的刀片进行旋转。这些刀片通常设计成交错排列，以便于对纸张进行剪切。 3. 进纸口：当用户将纸质文件放入进纸口时，纸张被送入到刀片区域。 4. 切削过程：在刀片旋转的过程中，纸张被逐渐切割成细小的碎片。 5. 出口与收集：切碎后的纸屑从机器的出口处排出，并落入收集箱中。 二、碎纸机的日常维护 为了确保碎纸机的长期稳定运行和良好的工作效果，日常的维护和保养是必不可少的。以下是一些日常维护的注意事项： 1. 清洁：定期清理碎纸机内部和外部的灰尘和杂物，以防止机器内部的堵塞和外部的腐蚀。 2. 润滑：根据碎纸机的使用情况，定期对机器内部的运动部件进行润滑，以减少磨损和摩擦。 3. 检查刀片：定期检查刀片是否锋利，如有需要可进行更换或研磨。 4. 避免过载：不要一次性放入过多的纸张进行切削，以免造成机器过载或卡纸。 5. 定期停机休息：长时间连续工作会使机器过热，影响其使用寿命。因此，应定期停机休息，让机器冷却。 6. 存放环境：碎纸机应存放在干燥、通风的地方，避免潮湿和高温环境对机器造成损害。 7. 电源安全：使用碎纸机时，确保电源插座稳定且安全接地，以防止电击事故的发生。 **Shredder's Operating Principle and Daily Maintenance** **Operating Principle of Shredder**: Shredders, commonly seen in offices, are devices used to cut paper documents into pieces for confidentiality protection. Their operation is primarily based on the power of mechanical cutting, as follows: 1. Power Supply and Start-up: When the user presses the power switch of the shredder, the internal motor starts to work. 2. Cutting Blades: The motor drives a set of sharp blades to rotate. These blades are usually arranged in a staggered manner to facilitate the cutting of paper. 3. Paper Entry: When the user inserts paper documents into the entry slot, the paper is fed into the blade area. 4. Cutting Process: As the blades rotate, the paper is gradually cut into small pieces.

5. Exit and Collection: The shredded paper pieces exit from the machine and fall into a collection box.

To ensure the long-term stable operation and good performance of the shredder, daily maintenance and care are essential. Here are some things to consider for daily maintenance: 1. Cleaning: Regularly clean the dust and debris on the inside and outside of the shredder to prevent blockages inside and corrosion outside. 2. Lubrication: Based on the usage of the shredder, regularly lubricate the moving parts inside the machine to reduce wear and friction. 3. Checking Blades: Regularly check if the blades are sharp. Replace or grind them if necessary. 4. Avoid Overloading: Do not put too many papers at once to avoid machine overload or paper jamming. 5. Regular Shutdown for Rest: Continuous long-term operation can cause the machine to overheat and affect its service life. Therefore, it is essential to regularly shut down for rest and allow the machine to cool down. 6. Storage Environment: The shredder should be stored in a dry and ventilated place, avoiding damp and high-temperature environments that can damage the machine. 7. Power Safety: When using the shredder, ensure that the power socket is stable and safely earthed to prevent electric shock accidents.
