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 ...
