The second conveying device is respectively connected with the weight detection device and the filter rod conveying belt of the filter rod forming equipment and is used for returning the sizing filter rods with qualified weight detection to the filter rod conveying belt of the filter rod forming equipment so as to avoid waste of the filter rods, and if the sizing filter rods with unqualified weight detection are conveyed to an unqualified filter rod collecting position through other conveying devices for corresponding treatment. And the third conveying device is respectively connected with the weight detection device and the blank filter stick storage device, and returns the detected blank filter sticks to the blank filter stick storage device to be supplied to the filter stick forming equipment.
The application also provides a filter stick glyceryl triacetate application amount calibration method, and the filter stick glyceryl triacetate application amount calibration system using any one of the above methods comprises the following steps:
s1, after the filter stick forming equipment enters a steady state production, the upper computer sends a sampling instruction to the filter stick forming equipment; the determination mode of the filter rod forming equipment entering the steady-state production is various, for example, the time is taken as a node, the equipment enters the steady-state production after being started and operated for a long time (for example, 5 minutes), or the filter rod forming equipment is considered to enter the steady-state production when the qualified rate of the sample reaches the set requirement through multiple times of active sampling.
According to corresponding program design, the upper computer sends sampling instructions to the filter rod forming equipment according to a set time interval, the time interval is usually fixed, such as 5 minutes, 10 minutes, 15 minutes and the like, in the technical scheme of the application, in order to improve the accuracy of the quality of the filter rod, the sampling interval can be correspondingly reduced, such as 3 minutes, 2 minutes or 1 minute and the like, but considering the production stability, the interval is optimally selected to be 5 minutes to 10 minutes.
And S2, controlling the automatic sampling device to extract the sizing filter rods according to the specified quantity by the filter rod forming equipment according to an instruction of an upper computer, and simultaneously, after the filter rod forming equipment closes a triacetyl glycerine application system according to the instruction of the upper computer, extracting the specified quantity of blank filter rods by the automatic sampling device. Specifically, after the filter rod forming equipment receives a sampling instruction of an upper computer, the automatic sampling device is controlled to start, the automatic sampling device extracts glue-applying filter rods (namely filter rods applying glyceryl triacetate) in a specified quantity from a filter rod conveying belt of the filter rod forming equipment according to a designed mode, 10 samples are taken as an example for explanation, in order to achieve accurate control, the quantity of samples sampled at a single time is not suggested to be too large, and the data after the quantity of the samples is too large can cause deviation reduction, so that the problems occurring in the actual production process are covered. Therefore, in this embodiment, 10 filter plugs are taken as an example for both the extracted size-applied filter plugs and the extracted blank filter plugs, and it should be noted that the number of size-applied filter plugs and the number of blank filter plugs sampled at a time are necessarily the same.

In a specific step S5, if the deviation is within the set range, the upper computer does not send a calibration instruction to the filter rod forming apparatus, and if the absolute value of the deviation exceeds the set range, the upper computer sends an instruction to the filter rod forming apparatus to calibrate the triacetin applying apparatus, and if the absolute value of the deviation is lower than the set range, the application amount of the triacetin applying apparatus is increased, and if the absolute value of the deviation is higher than the set range, the application amount of the triacetin applying apparatus is decreased. It should be noted that the calibration here is the calibration of the filter rod making apparatus to the triacetin application apparatus, and is used for adjusting the application amount of the triacetin to the triacetin application apparatus.

If the deviation is larger than the set value, the set value of the glyceryl triacetate applying equipment is high, and the set value of the glyceryl triacetate applying equipment is required to be reduced; if the deviation is smaller than the set value, it indicates that the set value of triacetin in the triacetin application equipment is low, and the set value of triacetin application in the triacetin application equipment should be increased.
