An online detection system and detection method for coating uniformity of reconstituted tobacco leaves by papermaking method

Abstract

The invention discloses a coating uniformity online detection system for paper-making reconstituted tobacco. The detection system comprises a near-infrared spectrum detection device, a mechanical movement scanning device, a reconstituted tobacco transferring device, a coating uniformity intelligent control device and a computer. A detector moves in a staggered mode to acquire spectrum data of different positions of reconstituted tobacco, and online fast detection of coating uniformity is achieved by means of a data processing and analyzing algorithm. The coating uniformity online detection system for the paper-making reconstituted tobacco performs real-time online detection on coating uniformity of the reconstituted tobacco in the production process, detection speed is high, and detection precision is high. When a detection result does not accord with requirements of uniformity production, information is fed back, coating uniformity can be conveniently controlled, production quality of the paper-making reconstituted tobacco is guaranteed, and production efficiency is improved.

Description

technical field [0001] The invention relates to a system for detecting coating uniformity of reconstituted tobacco leaves by papermaking method, in particular to an online detection system and detection method for coating uniformity of reconstituted tobacco leaves by papermaking method using near-infrared spectrum analysis technology. Background technique [0002] Reconstituted tobacco leaves are sheet or silk regenerated tobacco products (also called tobacco flakes) made by technically processing and recombining tobacco residues such as tobacco powder, shredded stems, and chips during cigarette processing. For the process quality control of reconstituted tobacco leaf products, the current production line has online control equipment for moisture, temperature, slurry concentration and density indicators, and other quality control is blank. Most of them are offline detection, and the results are lagging behind. Strong, such as online detection and feedback of product quantifi...

Problems solved by technology

However, the problem of this device is: complex operation, offline operation, cannot meet the needs of online operation, and does not analyze the coating uniformity

However, the problem with this device is that it is necessary to detect the solid content of the coating liquid on the film base, the operation is complicated, the detection of the coating uniformity cannot be realized, and the real-time intelligent control of the coating uniformity cannot be realized.
