Embodiment 1

[0016] like figure 1 The online detection and control system for coating amount of reconstituted tobacco leaves as shown includes scanning frame 1 before coating, scanning frame 2 after coating and its control cabinet 3, vehicle speed signal sensor 6, paper breaker, etc. Signal sensor 7, QCS operation station 4 connected to the scanning frame before coating and scanning frame after coating, server 5 for information exchange with control cabinet 3, QCS operation station 4, vehicle speed signal sensor 6, and paper break signal sensor 7 ; By scanning frame 1 before coating and scanning frame 2 after coating, the absolute dry weight of the substrate before coating and the absolute dry weight of reconstituted tobacco leaves after coating are detected, the coating amount is calculated, and the coating amount of reconstituted tobacco leaves is carried out on-line Detection control. The information interaction between the QCS operation station 4 and the scanning frame 1 before coatin...

Embodiment 2

[0024] 1) Detect the absolute dry weight of the film base: the operator opens the pre-coating scanning frame through the QCS operation station and the control cabinet, and when the film base passes the pre-coating scanning frame, the pre-coating scanning frame can detect the absolute dry weight of the film base 59g / m 2 ;

[0025] 2) Detect the absolute dry quantity of reconstituted tobacco leaves 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 sends the scanning frame and the pre-coating frame according to the calculated synchronization time difference After coating, the scanning frame sends out a synchronization command, and the scanning frame after coating acts as a slave frame to follow the scanning frame before coating to scan according to the synchronization command. During operation, the server will use the reverse edge time of the opera...

Embodiment 3

[0029] 1) Detect the absolute dry quantity of the film substrate before coating: the operator opens the pre-coating scanning frame through the QCS operation station and the control cabinet, and when the film substrate passes the pre-coating scanning frame, the pre-coating scanning frame can detect the The absolute dry weight is 61g / m 2 ;

[0030] 2) Detect the absolute dry quantity of reconstituted tobacco leaves 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 sends the scanning frame and the pre-coating frame according to the calculated synchronization time difference After coating, the scanning frame sends out a synchronization command, and the scanning frame after coating acts as a slave frame to follow the scanning frame before coating to scan according to the synchronization command. During operation, the server will use the reverse edge ...

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...
