Technical Field

[0001] This utility model relates to an assembly device, specifically a quick assembly device for a slitting circular blade bearing and shaft core, belonging to the field of slitting machine technology. Background Technology

[0002] Slitting is usually done using a slitting machine. The shaft on the slitting machine, also called the cutter shaft, is the main rotating shaft on which the circular cutter is mounted. It passes through the center hole of the entire circular cutter and is linked with the drive system of the equipment to drive the cutter to rotate. The bearing is a support component installed in the frame or shaft seat to support the shaft and enable it to rotate stably. Slitting circular cutters are arranged at intervals on the cutter shaft, and the fabric is slitted by the rotation of the slitting circular cutters.

[0003] In practical applications, after long-term use, the cutting edge of the slitting circular blade will become dull, leading to a decline in slitting quality, such as burrs, fraying, and uneven cross-sections. It is necessary to replace it in time to ensure product quality. However, when replacing the slitting circular blade, the shaft needs to be removed from the bearing on the blade holder. The existing bearing and shaft core mating structure of the slitting equipment is complex, mainly relying on tight fit, snap ring, or screw fixing. Tools are required for disassembly and assembly when replacing the slitting circular blade, which makes the assembly cumbersome, time-consuming, and labor-intensive.

[0004] Therefore, a quick assembly device for slitting circular blade bearings and shaft cores is proposed here. Utility Model Content
