Description

Dividing and conveying device for sheet materials

Technical field

The invention relates to the technical field of production of sheet-like materials such as flat printed matter, packaging bags, paper, etc., and in particular to a shunting and transmission device for sheet-like materials.

If automatic, mechanized stacking and packing of sheet materials are used, the conveying of sheet materials needs to be involved. When conveying sheet materials, shunt baffles on both sides are usually set to guide and limit the sheet materials to ensure that the sheet materials are neat and standardized during the conveying process and maintain straight transmission. However, due to the thin thickness, soft texture and light weight of the single sheet material, it is easy to produce wrinkles during the conveying process, and it is also easy to slip and accumulate due to the low friction with the conveying surface.
