Description

Scraper device suitable for reconstituted tobacco guide roller surface dehydration

Technical Field

The utility model relates to the technical field of tobacco equipment, in particular to a scraper device suitable for dehydrating roller surfaces of reconstituted tobacco guide rollers.

Background

In the production process of the tobacco leaf papermaking slice, the slice is sequentially coated, dried, formed, pre-pressed, packaged, bundled and the like along with a mesh blanket, a guide belt, a conveyer belt and the like, and finally the finished slice product is transported into a finished product warehouse for storage and standby.

The coated substrate paper enters a drying process, coating liquid can be attached to a drying net, a guide belt and a conveying belt in the conveying process of the paper, the paper can enter a gap between a tensioning return roller and a mesh blanket along with the drying net, the guide belt and the conveying belt due to the self adsorption capacity of the mesh blanket and the adhesion of the coating liquid, and therefore the paper is wound on the tensioning return roller, the axial diameter of the tensioning return roller is increased, the mesh blanket is too tensioned, and the situations of deviation or mesh blanket tearing and the like easily occur. When the paper winding condition of the tensioning return roller is serious and the bearing is enlarged, the service lives of the net blanket, the guide belt, the conveying belt and the guide roller are greatly shortened; in the production process, because the tensioning return roller rotates ceaselessly, paper wound on the roller surface is not easy to clean, mechanical damage is easy to cause, and potential safety hazards exist; the tensioning return roller can be replaced only by stopping the paper machine, so that the production continuity and the production efficiency are influenced, and the waste of manpower, material resources and energy sources is caused.
