Example Embodiment

[0015] Example 1

[0016] Such as figure 1 The shown on-line detection and control system for the coating amount of reconstituted tobacco leaves includes a pre-coating scan frame 1 and a post-coating scanning frame 2 and its control cabinet 3, a vehicle speed signal sensor 6, and a paper break that are arranged on the reconstituted tobacco leaf-based conveying paper machine Signal sensor 7, QCS operation station 4 connected to the scan frame before and after coating, and server 5 for information interaction with control cabinet 3, QCS operation station 4, vehicle speed signal sensor 6, and paper break signal sensor 7 ; Scanning frame 1 before coating and scanning frame 2 after coating are used to detect the absolute dry quantitative of the base before coating and the absolute dry quantitative of reconstituted tobacco after coating, calculate the coating amount, and perform on-line the coating amount of reconstituted tobacco Detection control. The information interaction between...

[0023] Example 2

[0024] 1) Detecting the absolute dry quantitative of the film base: the operator opens the scanning frame before coating through the QCS operating station and the control cabinet, and when the substrate passes through the scanning frame before coating, the scanning frame before coating can detect the absolute dry quantitative of the film base 59g / m 2 ;

[0025] 2) Detecting the absolute dry quantification of reconstituted tobacco after coating: start the scanning frame after coating, obtain the real-time speed of the paper machine through the speed signal sensor, and send the data to the server, and the server will scan the frame and the scanning frame before coating according to the calculated synchronization time difference. The scanning frame after coating sends out synchronization instructions, and the scanning frame after coating is used as the slave frame to follow the scanning frame before coating according to the synchronization instructions. During opera...

Abstract

The invention relates to a reconstituted tobacco coating quantity on-line detection control system and a control method of the system. The reconstituted tobacco coating quantity on-line detection control system comprises a before-coating scanning rack (1) and an after-coating scanning rack (2) as well as a control cabinet (3) thereof, a vehicle speed signal sensor (6), a paper breaking signal sensor (7), a QCS operating station (4) and a server (5), wherein the before-coating scanning rack (1) and the after-coating scanning rack (2) as well as the control cabinet (3) thereof are arranged on a reconstituted tobacco slice base conveying paper machine; the QCS operating station (4) is in information connection with the before-coating scanning rack and the after-coating scanning rack; the server (5) performs information interaction with the control cabinet, the QCS operating station, the vehicle signal sensor and the paper breaking signal sensor; the before-coating slice base absolute dry quantity and the after-coating reconstituted tobacco absolute dry quantity are detected by the before-coating scanning rack and the after-coating scanning rack, the coating quantity is calculated and the reconstituted tobacco coating quantity is subjected to on-line detection control. According to the reconstituted tobacco coating quantity on-line detection control system and the control method, the instant change condition of the coating quantity can be reflected in real time and is automatically adjusted and controlled timely, the manual sampling frequency can be greatly reduced, the operating stability of the coating system is improved, and the detection precision is improved, so that the quality stability of the reconstituted tobacco is improved.

Description

technical field [0001] The invention belongs to the technical field of production control of reconstituted tobacco leaves by papermaking method. Background technique [0002] The coating amount detection of the existing reconstituted tobacco leaf coating production line almost adopts the method of online random sampling and offline detection. The detection cycle is long, the detection workload is heavy, the sampling frequency is small, and the sampling amount is small, which cannot reflect the instantaneous change of the coating amount. , the guidance for production is not strong. With the continuous improvement of the production technology level and product quality requirements of the reconstituted tobacco industry, it is becoming more and more important to realize online detection and control of key indicators that affect product quality. Therefore, new technical means are needed to solve it. Contents of the invention [0003] The purpose of the present invention is to...
