Description

Technical Field

[0001] This utility model relates to the field of cigarette machinery and equipment technology, and more specifically, to a grinding wheel dressing device for the outer cylindrical grinding blade of a shredder in a cigarette making equipment. Background Technology

[0002] The diamond dressing mechanism of the surface grinder is a key component of the tobacco shredder. Tobacco leaves are cut into shreds of a certain width by a high-speed rotating shredder roller. The cutting edge and the gap between the blades affect the shredding quality. The cutting edge is sharpened by a grinding wheel, which is then dressed by a diamond. The gap between the blades is determined by the position of the diamond. The function of the external cylindrical grinder of the tobacco shredder is to adjust the shredder blades to the designed extension length. The grinding wheel is moved to contact the blades using a crank handle, and then the grinding wheel is moved to the diamond position using another crank handle, raising the diamond to contact the grinding wheel and then fixing it in place. The machine is then started to sharpen the blades. Once all blades are sharpened and the roller diameter is constant, the gaps of the lower blade, left and right side blades, and upper blade are adjusted to the standard range. At this point, the height of the diamond ensures the accuracy of the blade extension length and the gap between the blades.

[0003] However, existing grinding wheel dressers use traditional fixed bases, making maintenance and adjustment cumbersome and time-consuming, thus reducing work efficiency. Furthermore, continuous operation of the device often necessitates timely adjustments, leading to prolonged wear and tear, which reduces the efficiency and lifespan of diamond dressing.

[0004] Therefore, how to provide a grinding wheel dressing device for the outer cylindrical grinding blade of a filament cutting machine has become a technical problem that urgently needs to be solved in this field. Utility Model Content
