Problems solved by technology

However, the problem with this device is that the selected samples need to be dried, cooled, soaked, etc., which is an off-line detection method, and the detection time is as long as 2.5 hours, which cannot meet the production needs of rapid and on-line detection.
However, the problem with this device is that it is necessary to detect the solid content of the coating liquid after coa

Example Embodiment

[0056] The specific embodiments of the present invention are as follows:

[0057] Such as figure 1 As shown, an online detection device for the coating rate of reconstituted tobacco and its uniformity. This device includes a near-infrared moisture meter detection module 1, a mechanical motion scanning device 2, a reconstituted tobacco sheet conveying device 3, a main control center 4, and a signal transceiver Device 5;

[0058] The near-infrared moisture meter detection module 1 performs real-time detection on the tested reconstituted tobacco 6 entering the detection area, detects the moisture content and grammage information of the tested reconstituted tobacco 6, and outputs the corresponding information to the control center 4 The test data contains the moisture content and grammage data of the tested reconstituted tobacco 6;

[0059] The near-infrared moisture meter detection module 1 is installed on the mechanical movement scanning device 2 and controlled by the main control cen...

Example Embodiment

[0067] Example: In the field of quality control of the current paper-making process of reconstituted tobacco products, the coating uniformity and the stability control of the coating liquid play an important role in the quality of reconstituted tobacco products. The detection of coating rate and coating uniformity is proposed Very high requirements; therefore, the reconstituted tobacco sheet with a width of 0.8m is used as the object to be tested, and the reconstituted tobacco coating rate and its uniformity online detection device and method of the present invention are used for detection;

[0068] The near-infrared moisture meter detection module 1 includes two near-infrared moisture meters with exactly the same specifications; the measurement range of the near-infrared moisture meter detection module is 1-30%, and the measurement accuracy is controlled to 2σ≤±0.15 %, (where σ represents the standard deviation), the near-infrared moisture meter requires continuous operation for ...

Abstract

The invention discloses an on-line spreading rate and uniformity detecting device and an on-line spreading rate and uniformity detecting method for reconstituted tobacco. The detecting device comprises a near-infrared moister meter detecting module, a mechanical movement scanning and examining device, reconstituted tobacco flake conveying devices, a main control center and a signal receiving-transmitting receive. A near-infrared spectroscopic detection principle is adopted; a data processing and analysis algorithm is combined; the on-line quick detection of the spreading rate and the uniformity of the reconstituted tobacco is realized. By using the on-line spreading rate and uniformity detecting device and the on-line spreading rate and uniformity detecting method for the reconstituted tobacco, which are provided by the invention, the real-time on-line detection is carried out on the spreading rate and the uniformity of the reconstituted tobacco in a production process; information can be fed back when a detection result does not accord with a production requirement on the uniformity, so as to be convenient for timely adjustment and control; the detection speed is quick; the precision is high; the stability is good; the repeated calibration is not needed.

Description

technical field [0001] The invention relates to the technical field of detection of reconstituted tobacco leaves by a papermaking method, in particular to an on-line detection device and detection method for the coating rate and uniformity of reconstituted tobacco leaves using near-infrared spectral 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 quantification, coating...
