Description

Technical Field

[0001] This utility model relates to the field of rubber and magnetic cutting equipment technology, and in particular to a rubber and magnetic slitting rolling cutter. Background Technology

[0002] Rubber magnets possess excellent physical and stable chemical properties, making them widely used in daily production and life. During production, the rubber compounding ratio is adjusted according to application needs to first produce rubber magnet sheets of appropriate flexibility. These sheets are then cut into appropriately sized rubber magnet blocks using a cutting machine for use.

[0003] Currently, there are three main cutting processes for rubber magnetic sheets: water jet cutting, laser cutting, and metal blade cutting. Each has its advantages and disadvantages: water jet cutting can cut rubber magnetic sheets of varying flexibility and even those that are very thick, while ensuring high precision. However, the equipment has very high operating and maintenance costs. Laser cutting can cut rubber magnetic sheets of moderate thickness while maintaining high dimensional accuracy. However, the laser burns the rubber magnetic sheet, producing harmful gases. The cutting production also requires purification facilities, which limits its practical application. Metal blade cutting equipment has relatively low costs, but heat accumulates continuously during cutting, causing the rubber magnetic sheet to scorch and stick to the blade. This requires manual assistance in production, resulting in low production efficiency. Utility Model Content
