Problems solved by technology

At present, most tobacco factories in my country use random sampling static measurement methods to determine the structure of shredded tobacco (see industry standards: YC / T178-2003 Determination method of tobacco whole shred rate and shredded shred rate and YC / T278-2009 Determination of cigarette formula shredded tobacco structure), The instruments used can only rely on manual sampling, static detection, taking individual samples for each shift, static detection and analysis, and providing decision-making basis afterwards. Variations in the process, more difficult to control
At present, there is no equipment or method for directly measuring the structure of shredded tobacco online

Embodiment 1

[0036] Such as figure 1 As shown, a device for measuring the structure of shredded tobacco on-line mainly includes a vibrating screen 2, an air duct 6, a pneumatic flap 5, a tobacco end pipe 7, an end product box 8, an electronic scale 9, and a control processor 10. The sieve 2 includes a feed end and a discharge end. The air duct 6 is located below the discharge end of the vibrating screen. The air duct 6 is provided with a side hole, and the tobacco powder pipe 7 connects the air duct 6 with the product through the side hole. The end box 8 is connected, the electronic scale 9 is arranged under the end product box 8, and is connected with the control processor 10, one end of the pneumatic flap 5 is fixed on the side hole of the air duct, and the other end is a free end that can be turned over arbitrarily.

[0037] The powder accumulation funnel 4 placed under the vibrating sieve 2 is respectively connected to the negative pressure air pipe 6 and the smoke powder pipe 7 throug...

Embodiment 2

[0039] Such as figure 1 As shown, the shredded tobacco 1 to be tested is passed through the vibrating sieve 2, and samples are taken 3 times at the feed end and the discharge end of the vibrating sieve 2 respectively, and each sampling amount is 1 kg. a=1.76%, the average value of end content at the discharge end b=0.73%.

[0040] thereby according to The model calculation of the shredded tobacco vibration sieving rate η=58.5%.

[0041] Pass the shredded tobacco 1 to be tested through the vibrating sieve 2, open the pneumatic flap 5, and detect the weight m of the tobacco powder screened within 5 minutes, and at the same time take a sample at the feeding end and determine the structure of the shredded tobacco to be tested in the laboratory (whole shred rate W, broken Silk rate B).

[0042] Randomly detect 10 times, establish the relationship model between the structure of the shredded tobacco to be tested, the weight m of tobacco powder, and the screening rate η, and input...

Embodiment 3

[0054] Such as figure 1 As shown, the shredded tobacco 1 to be tested is passed through the vibrating sieve 2, and samples are taken 3 times at the feed end and the discharge end of the vibrating sieve 2 respectively, and each sampling amount is 1 kg. a=1.76%, the average value of end content at the discharge end b=0.73%.

[0055] thereby according to The model calculation of the shredded tobacco vibration sieving rate η=58.5%.

[0056] Pass the shredded tobacco 1 to be tested through the vibrating sieve 2, open the pneumatic flap 5, and detect the weight m of the tobacco dust screened within 3 minutes. Silk rate B).

[0057] Randomly detect 10 times, establish the relationship model between the structure of the shredded tobacco to be tested, the weight m of tobacco powder, and the screening rate η, and input the model parameters into the control processor.

Description

[0001] technical field [0002] The invention relates to a tobacco processing detection technology and equipment, in particular to a method and equipment for measuring the structure of shredded tobacco online by using a weighing method. [0003] Background technique [0004] In the cigarette production and processing process of the tobacco industry, as well as in the quality inspection of cigarette products, the cut tobacco size detection of shredded tobacco is an important link, which clearly reflects the various processes of cigarette shreds, shredded tobacco blending, and crimping. In terms of quality control, the cut tobacco structure of finished cigarettes also directly affects the physical and sensory qualities of cigarettes. At present, most tobacco factories in my country use random sampling static measurement methods to determine the structure of shredded tobacco (see industry standards: YC / T178-2003 Determination method of tobacco whole shred rate and shredded shr...
