Grinding unit for sharpening disc-shaped cutting blades
The granted patent US12011798B2 describes a grinding unit specifically designed for sharpening disc-shaped cutting blades. The unit features a slide that can be adjusted towards or away from the cutting blade, equipped with at least two grinding wheels positioned to engage the cutting edges' flanks. The design includes arms that support the grinding wheels, which can rotate under the influence of gravity when not locked in place, allowing for automatic contact with the blade's flanks. The grinding wheels can be adjusted in position and are driven into rotation by friction with the cutting blade, enhancing the efficiency of the grinding process.
Additionally, the patent outlines a cutting machine that incorporates this grinding unit, facilitating the sharpening of the cutting blade while it is in operation. The grinding unit can utilize multiple pairs of grinding wheels, each with distinct features such as size and hardness, to optimize the grinding sequence based on the specific characteristics of the product being cut. The system includes control mechanisms that can adjust the pressure applied by the grinding wheels, ensuring consistent performance. Furthermore, the integration of load cells allows for real-time monitoring of the pressure exerted during grinding, enabling precise adjustments to maintain optimal cutting conditions.
