[0027] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0028] See also Figure 1 As shown, the device provided in the present application can flexibly take out representative samples according to actual production conditions, and can disperse the obtained samples to make them more conducive to the next step of tobacco morphology detection.

[0029] The present application provides an online sampling device for tobacco morphology measurement equipment, comprising a sampling mechanism, a gas-solid separation mechanism and a weighing and feeding mechanism, wherein the sampling mechanism is connected to a feed port of the gas-solid separation mechanism, and the weighing and feeding mechanism is arranged below the gas-solid separation mechanism.

[0030] The sampling mechanism of the present application includes a sampling tube 1 and a tobacco delivery tube 2 connected to the sampling tube, and the sampling tube is composed of an adjustable telescopic sleeve. Specifically, the sampling tube is a cylindrical sleeve with a small bottom and a large top, a small inside and a large outside, and a lower outer diameter of 3-8 cm, a lower inner diameter of 2-6 cm, an upper outer diameter of 5-14 cm, and an upper inner diameter of 6-10 cm. This design enables the sampling tube to achieve a certain degree of freedom to move up, down, left, and right.

[0031] The gas-solid separation mechanism of the present application includes a cyclone separator 3 and a butterfly-shaped air lock device 5 arranged below the cyclone separator. A negative pressure pipe 4 is arranged above the cyclone separator, and the butterfly-shaped air lock device is controlled by a first servo motor.

[0032] In the present application, a tobacco conveying belt 6 is arranged below the butterfly air lock device, and is located 20-50 cm below the butterfly air lock device, which can effectively prevent material blockage. The weighing and feeding mechanism includes an online weighing device 7 and a tobacco feeding device, wherein the online weighing device is arranged on one side of the tobacco conveying belt, and the tobacco feeding device is arranged at the end of the online weighing device.

[0033] The present application also includes a data processing module, which is electrically connected to the online weighing device.

[0034] The present application also provides an online sampling method for a tobacco morphology measuring device, using any of the above-mentioned online sampling devices for tobacco morphology measuring devices, comprising the following steps:

[0035] S1. According to the set sampling time, move the sampling tube to the set position above the tobacco production line; the specific sampling time can be set by those skilled in the art according to needs.

[0036] S2 opens the negative pressure tube and uses negative pressure to take samples on the tobacco production line, and during the sampling process, keeps the sampling tube swinging evenly up and down and left and right; in this application, the specific suction force of the negative pressure on the sample tobacco cannot cause the tobacco to break up, so as to avoid affecting the accuracy of the final data.

[0037] S3. The sample tobacco passes through the sampling tube and the tobacco conveying tube and enters the cyclone separator for gas-solid separation.

[0038] S4. The sample tobacco after gas-solid separation falls freely onto the tobacco conveyor belt after passing through the air lock device for secondary dispersion pretreatment; after the tobacco falls freely onto the tobacco conveyor belt, the sample tobacco is dispersed.

[0039] S5. After the sample tobacco has undergone secondary dispersion pretreatment, it is weighed by an online weighing device, and the online weighing device transmits the weight data to the data processing module.

[0040] S6. The weighed tobacco is transferred to a tobacco feeding device, and after a third dispersion treatment, the sample tobacco is fed into a tobacco morphology analyzer. In the present application, the tobacco feeding device feeds the sample tobacco into the tobacco morphology analyzer in a dialing manner.

[0041] According to the belt laying situation of the production line, move the telescopic sleeve of the online sampler forward, backward, left and right, move the sampling end of the sampler to the target sampling point, start the negative pressure device, absorb a certain amount of representative tobacco sample, and the tobacco passes through the sampler to the tobacco conveying pipe and enters the cyclone separator. The top of the cyclone separator is connected to the negative pressure pipe, and an air lock device is provided at the bottom. After passing through the air lock, the tobacco enters the sample delivery device. The end of the sample delivery conveyor belt is equipped with an online weighing device. The weighing device weighs an appropriate amount of tobacco and then performs tobacco morphology detection.

[0042] When in use, by placing the sampling tube at the required sampling position, free horizontal and vertical movement sampling can be achieved. The tobacco enters the cyclone separator through the tobacco conveying pipe. The air outlet on the top of the cyclone separator is connected to the negative pressure pipe. The negative pressure pipe provides power for the tobacco conveying. During the negative pressure conveying process, the tobacco is dispersed for the first time and gas-solid separation is achieved under the action of the cyclone separator. The lower part of the cyclone separator is a butterfly-shaped air lock device, which can effectively prevent the tobacco from agglomerating again. The cyclone separator is not connected to a belt-type electronic scale. The taken tobacco is weighed and the obtained data is fed back to the computer terminal for better analysis of the tobacco morphology data. A tobacco conveying device is connected to the back of the belt-type electronic scale. The device sends the tobacco into the tobacco morphology analyzer for analysis in a dialing manner.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
