**碎纸机的工作原理及使用注意事项** 一、碎纸机的工作原理 碎纸机是一种办公设备，主要用于将纸质文件切割成小片，以达到保密或空间节约的目的。其工作原理大致如下： 1. 供电与启动：碎纸机通过外部电源供电，当用户按下启动开关时，电机开始工作。 2. 纸张进入：待处理的纸张通过进纸口进入机器内部。 3. 切割过程：电机驱动切割刀片进行高速旋转，将进入机器的纸张切割成细小的碎片。 4. 碎片排出：切割后的纸屑通过机器内部的排纸口排出，部分高端碎纸机还具备碎纸收集箱以收集纸屑。 5. 安全保护：部分碎纸机具备过热保护和过载保护功能，当机器过热或过载时会自动停机，保护电机和刀片。

二、使用碎纸机的注意事项 1. 安全操作：在使用碎纸机时，应确保电源线不损坏、不乱拉乱扯，避免触电危险。同时，不要让儿童接近正在工作的碎纸机，以防意外伤害。 2. 纸张类型与数量：选择适合碎纸机处理的纸张类型和数量。避免放入金属、钉子等硬物，以免损坏刀片或电机。 3. 连续工作时间：避免让碎纸机长时间连续工作，以免机器过热导致损坏。如果需要处理大量纸张，可分批次进行。 4. 清洁与维护：定期清洁碎纸机内部和外部，保持其良好的工作状态。如发现刀片变钝或机器出现故障，应及时联系专业人员进行维修。 5. 存储与放置：将碎纸机存放在干燥、通风的地方，避免潮湿环境导致机器损坏。同时，确保碎纸机放置平稳，避免工作时产生噪音或振动。 **Translation**: **The Working Principle and Precautions for Using Shredder** I. The Working Principle of Shredder A shredder is an office equipment that is mainly used to cut paper into small pieces for confidentiality or space-saving purposes. Its working principle is roughly as follows: 1. Power Supply and Startup: The shredder is powered by external power and when the user presses the start switch, the motor starts to work. 2. Paper Entry: The paper to be processed enters the machine through the paper feed port. 3. Cutting Process: The motor drives the cutting blade to rotate at high speed, cutting the entered paper into small pieces. 4. Chip Discharge: The cut paper fragments are discharged through the paper discharge port inside the machine, and some high-end shredders also have paper collection boxes to collect the fragments.

5. Safety Protection: Some shredders have overheat and overload protection functions that will automatically shut down the machine when it overheats or is overloaded, protecting the motor and blade.

II. Precautions for Using Shredder 1. Safe Operation: When using the shredder, ensure that the power cord is not damaged or tangled, avoiding the risk of electric shock. At the same time, keep children away from the shredder while it is operating to prevent accidental injuries.

2. Paper Type and Quantity: Choose the appropriate paper type and quantity for the shredder. Avoid putting metal, nails, and other hard objects to prevent damage to the blade or motor.

3. Continuous Working Time: Avoid letting the shredder work continuously for a long time to prevent overheating and damage. If you need to process a large amount of paper, you can do it in batches. 4. Cleaning and Maintenance: Regularly clean the inside and outside of the shredder to maintain its good working condition. If the blade becomes dull or the machine malfunctions, contact a professional for repair in a timely manner. 5. Storage and Placement: Store the shredder in a dry and ventilated place to avoid damage caused by a humid environment. Ensure that the shredder is placed steadily to avoid noise or vibration during operation.
