To ensure the cutting quality of paper and printed materials, it is necessary to maintain the paper cutting machine in daily life. The key points for daily maintenance of the paper cutting machine are as follows:
1. Choose appropriate hydraulic oil according to different seasons. Use No. 20 engine oil in winter to maintain the fluidity of the paper cutter; Use No. 30 engine oil in summer to maintain the viscosity of the paper cutter.
2. Maintain appropriate hydraulic pressure. Excessive pressure can cause the sealing ring to burst; The pressure is too low, and the blade cutting appears sluggish and weak.
3. Coat the paper cutting platform and blade opening with talcum powder or paraffin. By doing so, one is to reduce the frictional resistance between the paper and the platform, which saves labor in operation; The second is to extend the cutting frequency of the blade, ensuring a smooth and neat cutting edge of the paper.
4. Add lubricating oil. Before work, lubricating oil should be added to the mechanical oil injection port to keep the machine lubricated, clean, and noise free, so that the paper cutting machine is often in good working condition.
