Technical Field

[0001] The utility model relates to the technical field of tobacco manufacturing, in particular to a tobacco leaf dropping tube for a shredder. Background Art

[0002] In the tobacco processing industry, the shredder is an essential piece of equipment on the tobacco production line. Its primary function is to cut tobacco leaves into uniform strands for subsequent rolling and other processes. The smooth flow of the tobacco drop tube during operation directly impacts the shredding effect and the efficiency of the entire production line. However, due to the physical properties of tobacco leaves, such as moisture and fiber structure, as well as friction during transportation, the drop tube is prone to clogging.

[0003] Traditional unclogging methods rely primarily on manual labor, such as using wooden sticks or specialized tools to knock or vibrate the clogged tobacco leaves. This method is not only inefficient but also prone to damage to the drop tube and even poses safety concerns. Furthermore, since the shredder typically operates continuously, stopping the machine for unclogging can severely impact production schedules and efficiency.

[0004] In recent years, with the continuous development of automation technology, advanced unclogging devices have begun to be introduced into wire cutters. Most of these devices use pneumatic conveying or mechanical unclogging methods, capable of unclogging the blanking tube without stopping the machine. However, due to the complex and changing working environment of wire cutters, existing unclogging devices still have certain limitations in adaptability and effectiveness, and cannot fully meet production needs.

[0005] Therefore, it is necessary to develop a novel tobacco leaf drop pipe dredging device for a cutting machine to overcome the shortcomings of the prior art. Utility Model Content
