Embodiment 1
[0022] The gluing process optimization method based on filter ventilation rate control in this embodiment.
[0023] Step (1), take samples for each shift on different machines in continuous production
[0024] A. Sample specification: Take a certain domestic brand of cigarettes.
[0025] B. Sampling quantity and frequency: Samples are taken once per shift on the continuous production machine, one sample each time, and 5 consecutive days of sampling, that is: 1 sample / shift / machine×5 days.
[0026] C. Sampling machine: machines No. 1, 2, 3, 4, 5, 6, and 7 (M5 model) in Zone B of the packaging workshop.
[0027] Step (2), the filter tip ventilation rate of the sample of detection step (1);
[0028] A. Detection indicators
[0029] The physical indicators to be tested include: filter ventilation rate, total ventilation rate, weight, draw resistance (PD), and closed draw resistance (CPD), which are tested according to the requirements of the national cigarette standard. Table ...
Embodiment 2
[0105] The gluing process optimization method based on filter ventilation rate control in this embodiment.
[0106] In step (4), build model 2 (without intercept)
[0107]
[0108] Table 21 Test of Intersubject Effect of Interaction of Spray Glue and Glue
[0109]
[0110] From the analysis of the above model, it can be seen that:
[0111] The significance probability Sig. values of model 2 are all 0, far less than 0.05, indicating that the model is applicable, but from R2, no intercept model is preferred. The model passed the variance homogeneity test, and the factor (glue), factor (glue spraying method), and factor (glue*glue spraying method) all had a significant impact on the index (filter tip ventilation rate).
[0112] Table 22 Pairwise comparison of the interaction between spray glue and glue based on Model 2
[0113]
[0114] It can be seen from Table 22 that both levels of the factor (glue spraying method) have a significant impact on the index (filter t...

Abstract
The invention relates to a gluing process optimization method and a filter tip ventilation rate control method, the optimization method comprises the following steps: taking samples on each shift fromdifferent machine tables in continuous production, wherein e glue brands and glue spraying modes on at least two machine tables are different from glue brands and glue spraying modes of other machinetables; detecting one or more of the filter tip ventilation rate, the total ventilation rate, the weight, the suction resistance and the closed suction resistance of the samples; analyzing the significance of different glue brands and glue spraying modes to one or more of the filter tip ventilation rate, the total ventilation rate, the weight, the suction resistance and the closed suction resistance of the samples; performing validation on results, and selecting optimal combination of the glue brands and glue spraying modes. According to the method, the influence of the different glue brandsand different glue spraying modes and the interaction effect of the different glue brands and different glue spraying modes on the filter tip ventilation rate is analyzed, a model of the filter tip ventilation rate and the different glue brands and different glue spraying modes is established, and a foundation is laid for the research and development of tipping glue which is capable of reducing the filter tip ventilation rate under glue spraying mode, improving fluidity and adhesion property, and is suitable for the glue spraying mode.
Description
technical field [0001] The invention relates to a method for optimizing the gluing process, and also relates to a method for controlling the ventilation rate of the filter tip. Background technique [0002] The control of the filter ventilation rate is an important indicator affecting the quality of cigarettes. There are many indicators that affect the filter ventilation rate. The instability of indicators will lead to fluctuations in smoke, which will ultimately affect the stability of cigarette product quality. [0003] Our research found that the gluing method can affect the stability of the filter ventilation rate, and the differences between machines are more concentrated in the differences in the gluing method. Therefore, it is necessary to analyze the water-based glue and gluing method of different brands. The analysis of the impact of the spraying method will lay the foundation for the research and development of tipping glue suitable for the spraying method to redu...
