[0002] The slitting machine is a key equipment in metal plate processing, and is used for cutting wide metal coiled material into multiple narrow strips. With the increasing demand for high-speed cutting, the blade wear problem is increasingly prominent. At present, the industry generally uses hard alloy blades, and the service life of the blades directly affects the production efficiency and cost.

Therefore, the current blade lubrication is mainly achieved by manually applying lubricating grease at regular intervals. The operator manually brushes the blades every 2 hours. This method is simple but affects the continuity of production, and manual application of lubricating grease also has safety hazards. Therefore, the slitting machine capable of automatically lubricating blades is improved. CONTENT OF THE INVENTION
