What is a slitting machine? A slitting machine is a mechanical device that cuts wide paper, mica tape or film into multiple narrow materials. It is often used in papermaking machinery, wire and cable mica tape, and printing and packaging machinery. The slitting machine is mainly used for cutting non-woven fabrics; mica tapes, paper, insulating materials and various film materials, especially for cutting narrow tapes (non-woven fabrics, paper, isolation materials, mica tapes, films, etc.). Next, let the slitting machine manufacturer Tongli Precision introduce to you how we should check the quality of the slitting machine blade welding? We need to know that the quality of the slitting machine blade welding is more important to the use of the slitting machine.

How to check the quality of slitting machine blade welding?

1. Check the strength of the weld seam: Grind the back of the turning tool with a green silicon carbide grinding wheel, and check the thickness of the solder layer, which is required to be less than 0.15mm.

2. Check the position of the blade in the cutter slot: If the cutter feels the blade bed is aligned, re-solder.

3. Check the welding strength: moderately tap the blade with a wooden hammer or copper hammer, if the blade does not fall off from the groove, it is qualified.

4. Check the flatness of the blade: If there are pits on the blade of the slitter, it means that the blade is overheated and deformed, and the new blade should be burned and re-welded.

5. Check for cracks: After cleaning with kerosene, whether there are cracks in the blades. The kerosene seeps into the cracks and black lines appear, visible to the naked eye.
