Problems solved by technology

[0004] Before the rehydrated tobacco stems are treated with a briquetting machine, it is often impossible to judge whether the briquetting precision of the briquette machine can meet the requirements of the process standard. This is a technical problem in the existing briquetting process. Some tests The method of pressing the thickness of the stem is to take the pressed stem at the outlet of the pressing machine as the detection object. Since the tobacco stem will rebound to a certain extent after being squeezed, the thickness of the tobacco stem tested at this time cannot really represent the actual pressed stem. thickness

Embodiment 1

[0024] In the case of setting the process standard for the thickness of the stem to be 1.2±0.2mm, select 9 fuses with a diameter of 2.40mm and a length of 15cm, and divide them into 3 groups with 3 fuses in each group. Center 1, Right 1; Left 2, Center 2, Right 2; Left 3, Center 3, Right 3. After the 3 fuses were processed by the stemming machine at the same time according to the group, the thickness of the fuses were detected with a vernier caliper, and the results are shown in Table 1 below:

[0025] Table 11.2mm pressure stem thickness

[0026]

[0027] Left average value = (left 1 + left 2 + left 3) ÷ 3 = 1.183

[0028] Average value = (medium 1 + medium 2 + medium 3) ÷ 3 = 1.210

[0029] Right average value = (right 1 + right 2 + right 3) ÷ 3 = 1.203

[0030] Overall average = (left average + middle average + right average) ÷ 3 = 1.199

[0031] From Example 1, the following conclusions can be drawn: the overall average value and the average values ​​of the left, mi...

Embodiment 2

[0033] In the case of setting the process standard for the thickness of the stem to be 1.6±0.2mm, select 9 fuses with a diameter of 2.78mm and a length of 20cm, and divide them into 3 groups with 3 fuses in each group. Center 1, Right 1; Left 2, Center 2, Right 2; Left 3, Center 3, Right 3. After the 3 fuses were processed by the stemming machine at the same time according to the group, the thickness of the fuses were respectively detected with a vernier caliper. The results are shown in Table 2:

[0034] Table 21.6mm stem thickness

[0035]

[0036] Left average value = (left 1 + left 2 + left 3) ÷ 3 = 1.493

[0037] Average value = (medium 1 + medium 2 + medium 3) ÷ 3 = 1.880

[0038] Right average value = (right 1 + right 2 + right 3) ÷ 3 = 1.563

[0039] Overall average = (left average + middle average + right average) ÷ 3 = 1.645

[0040] Can draw the following conclusions from embodiment 2: although the left average value, the right average value and the overall a...

Abstract

The invention provides a method for detecting the thickness of a flattened stem, belonging to a method for detecting the thickness of a stem flattened by a stem flattener by utilizing fuses. The method comprises the following steps: selecting 9-30 fuses in certain size and length, and making marks, wherein the diameter and length of each fuse respectively range from 1.00mm to 3.50mm and 10cm to 30cm; under normal production conditions, respectively putting 3-10 fuses at the left part, middle part and right part of a feeding hole of a stem flattener, and taking the fuses out of a discharge hole of the stem flattener after extrusion; using a vernier caliper to test the thickness of each fuse, and respectively calculating the average thickness of each of the left, middle and right groups of fuses; and repeating the above steps 3-5 times, then calculating the total average thickness according to the average thickness of the three groups of fuses during each testing, and polishing a rollerof the stem flattener if either the average thickness of each of the left, middle and right groups of fuses or the total average thickness exceeds the requirement of the process standard. The method has the advantages of rapid and accurate detection of thickness of the flattened stem and high detection efficiency.

Description

technical field [0001] The invention relates to a method for detecting the thickness of a stem in the cigarette industry, and is characterized in that a fuse is used to detect the thickness of a stem of a stem pressing machine. Background technique [0002] Tobacco stem is the main residue after the primary roasted tobacco leaves are separated from the leaves in the threshing and re-baking factory. The stem content refers to the mass fraction (%) of tobacco stems in the tobacco leaves. The stem content of tobacco leaves is affected by the type of tobacco leaves. Variety, the part where the tobacco leaf grows, the shape and thickness of the leaf, the thickness of the stem, etc. The relationship of stem content rate of different varieties of tobacco leaves was flue-cured tobacco>burley tobacco>oriental tobacco. Generally, the stem content rate of flue-cured tobacco is 24-30%, with an average of about 25%. Tobacco leaves have different planting positions, and the stalk...
