Description

Technical Field

[0001] The utility model relates to the field of cleaning the spike teeth of a tobacco leaf redrying feeder, in particular to a device for cleaning the spike teeth of a tobacco leaf redrying feeder. Background Art

[0002] Currently, the cleaning device for feeder spikes uses a brush structure. The brush usually uses a four-twist double-column PE wire. After cleaning, large particles will stick to the PE wire, reducing the brush's cleaning effect. As a result, the brush cannot effectively remove the dirt remaining in the spikes and the gaps between the spikes. In addition, the brush has no fixed shape and cannot completely conform to the surface of the spikes, often resulting in incomplete cleaning of the spikes. Especially when the spike surface is complex or has a special shape, the brush may not effectively contact all areas that need to be cleaned. Long-term use will cause the brush to wear, reducing cleaning effectiveness. At the same time, brush replacement will increase maintenance costs.
