美工刀保养秘诀与故障排除 一、保养秘诀 1. 保持刀片清洁：经常清洁刀片上的污垢和杂质，以避免刀片生锈。使用后，应将刀片上的油墨、胶水等残留物清洗干净。 2. 定期磨刀：定期用磨刀器或砂纸轻轻打磨刀片，保持刀片锋利。这样不仅可以延长刀片的使用寿命，还能保证切割效果。 3. 正确存放：将美工刀存放在干燥、阴凉的地方，避免阳光直射和潮湿环境。同时，避免将美工刀与其他金属物品混放，以免发生碰撞导致刀片受损。 4. 定期更换刀片：当刀片变钝或损坏时，应及时更换新的刀片。不要试图用锤子或其他工具敲击刀片，以免造成刀片断裂或变形。

二、故障排除 1. 刀片卡住：如果刀片在切割过程中卡住，可能是由于刀片过钝或切割物过厚。此时，可以尝试更换新的刀片或调整切割物的厚度。 2. 刀片松动：如果发现刀片松动，可能是由于刀片固定螺丝松动或损坏。此时，应检查并拧紧螺丝，如螺丝损坏则需更换新的螺丝。 3. 刀身弯曲：如果发现刀身弯曲，可能是由于不当使用或碰撞导致。此时，可以尝试用热水浸泡刀身，然后轻轻调整至原状。注意，这个过程需要耐心和细心，避免用力过猛导致刀身断裂。 4. 不出纸屑：如果在使用过程中发现无法切割出纸屑，可能是刀片太钝或者不干净。此时需要清理和磨利刀片，如果仍无法解决问题，则需更换新的刀片。 英文翻译: Secrets of Maintenance and Troubleshooting for Utility Knife I. Secrets of Maintenance 1. Keep blade clean: Regularly clean the blade from dirt and impurities to prevent rusting. After use, clean the residual ink, glue, and other substances on the blade. 2.

This can not only extend the service life of the blade but also ensure cutting efficiency. 3. Proper storage: Store the utility knife in a dry and cool place, avoiding direct sunlight and damp environments. At the same time, avoid mixing the utility knife with other metal objects to prevent collisions that may damage the blade. 4. Regularly replace the blade: When the blade becomes dull or damaged, replace it with a new one in a timely manner. Do not try to hit the blade with a hammer or other tools to avoid blade fracture or deformation.

1. Blade stuck: If the blade gets stuck during cutting, it may be due to a dull or too thick cutting object. At this time, you can try replacing the blade or adjusting the thickness of the cutting object. 2. Blade loose: If the blade becomes loose, it may be due to a loose or damaged blade fixing screw. At this time, check and tighten the screw, and if the screw is damaged, replace it with a new one. 3. Curved blade: If the blade is found to be curved, it may be due to improper use or collision. At this time, you can try soaking the blade in hot water and gently adjust it back to its original shape. Note that this process requires patience and care to avoid excessive force that may cause the blade to break. 4. No paper shreds: If it is found that paper shreds cannot be cut during use, it may be due to a dull or unclean blade. At this time, you need to clean and sharpen the blade, and if the problem still persists, replace the blade with a new one.
