Tobacco sheet coating device and method

Abstract

The invention discloses a tobacco sheet coating device. The tobacco sheet coating device comprises hot air drying equipment, net pressing equipment, a tension roller frame and a winding device which are arranged in sequence, the hot air drying equipment comprises a conveying unit and a drying unit, and the drying unit is arranged below the conveying unit and used for drying the tobacco sheets borne on the conveying unit; the net pressing equipment is connected with the conveying unit and used for pressing the dried tobacco sheets; the tension roller frame is connected with the net pressing equipment; and the winding device is connected with the tension roller frame and used for winding the tobacco sheets. According to the tobacco sheet coating device and method provided by the invention, the situation that the material is cracked or fractured due to tension during rolling can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of tobacco machinery, and more specifically, relates to a tobacco sheet coating device and method. Background technique [0002] Tobacco sheet is processed tobacco waste such as tobacco stems, tobacco powder and low-grade tobacco leaves in the process of cigarette production to produce sheet-shaped tobacco regenerated raw materials that meet the requirements of cigarette formula. Tobacco sheet is blended with natural tobacco leaves in a certain proportion Made into cigarettes. [0003] There are three main processes for manufacturing tobacco sheets, namely: radial pressure method, thick pulp method, and papermaking method. When the papermaking method is used to produce tobacco sheets, the coating of the sheets usually uses a dipping or roller coating device similar to paper surface sizing. . In order to tighten the material during winding, the material will inevitably produce a certain amount of tension, b...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a tobacco sheet coating device, which solves the problem that due to the low strength of the material, when the humidity of the material after coating is high, it cannot be subjected to tension, and its free state is basically free from tension, although the humidity of the dried material is reduced. , resulting in the ability to withstand a small amount of pulling force, but it is still unable to guarantee that it can withstand the pulling force that it needs to withstand during winding, which will cause cracks or even breakage of the material during winding, which seriously affects the quality of finished tobacco sheets and the production efficiency. It can effectively reduce the occurrence of cracks or breakage of materials under tension during winding
