Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figures 1-4 This utility model provides a technical solution:

[0026] like Figures 1-4 As shown, a pneumatic conveying system for tobacco leaf sampling and testing in the tobacco industry is located on one side of a baler 1. The baler 1 is equipped with a sampling component 11, including a sampling bottle 5, a ring conveyor frame 2, and a pneumatic conveying component 3. The baler 1 and the pneumatic conveying component 3 are located at opposite ends of the ring conveyor frame 2.

[0027] The annular conveyor frame 2 includes a support frame 23, a conveyor chain 21 and a drive motor 22. The conveyor chain 21 is located on the support frame 23. The drive motor 22 is fixed on the support frame 23 and is connected to the conveyor chain 21 for transmission. The conveyor chain 21 is provided with a plurality of limiting cylinders 25, and the limiting cylinders 25 are open at both the upper and lower ends.

[0028] The pneumatic conveying assembly 3 includes a feeding box 31 and an outlet box 33. The feeding box 31 is provided with a feeding port 32, which is located below the opening 26. The outlet box 33 is provided with a discharge port 34, which is located above the limiting cylinder 25.

[0029] Through the above technical solution, a tobacco sample is obtained by the sampling component 11 of the packaging machine 1, and then an empty sampling bottle 5 is taken out from the limiting cylinder 25. The tobacco sample is put into the sampling bottle 5 and the cap is tightened. Then the sampling bottle 5 is placed into the empty limiting cylinder 25. Since the limiting cylinder 25 is open at both ends and a bottom plate 24 is provided below the limiting cylinder 25, the bottom of the sampling bottle 5 will fall on the bottom plate 24 below and be supported by the bottom plate 24.

[0030] Furthermore, the inner diameter of the limiting cylinder 25 is larger than that of the sampling bottle 5, so that the sampling bottle 5 after sampling can be easily inserted into the limiting cylinder 25; and the distance between the limiting cylinder 25 and the bottom plate 24 is less than the height of the sampling bottle 5, so that after the sampling bottle 5 falls on the bottom plate 24, a part of the sampling bottle 5 will still be limited by the limiting cylinder 25, and the sampling bottle 5 will not completely detach from the limiting cylinder 25.

[0031] Furthermore, the distance between the highest point of the limiting cylinder 25 and the bottom plate 24 is less than the height of the sampling bottle 5, which ensures that after the sampling bottle 5 is inserted into the limiting cylinder 25, the upper end of the sampling bottle 5 will protrude from the limiting cylinder 25, making it convenient for staff to take out the empty sampling bottle 5 from the limiting cylinder 25.

[0032] As the drive motor 22 drives the conveyor chain 21 to make a circular motion, the limiting cylinder 25 is connected to the conveyor chain 21 through the connecting rod. The limiting cylinder 25 is fixed on the outside of the conveyor chain 21, which makes it convenient for the staff to take out or put in the sampling bottle 5 on one side of the conveyor chain 21.

[0033] The circular rotation of the limiting cylinder 25 will cause the sampling bottle 5 inside to move in a circular motion, and the bottom of the sampling bottle 5 will be held in place by the bottom so that it will not fall.

[0034] Since the bottom plate 24 has an opening 26 at one end near the annular conveyor 2, and the opening 26 is located on the moving path of the limiting cylinder 25, when the limiting cylinder 25 moves the sampling bottle 5 above the opening 26, the sampling bottle 5 inside the limiting cylinder 25 will fall from the opening 26 of the bottom plate 24 into the lower delivery port 32. At this time, the sampling bottle 5 will enter the delivery box 31 and be sent by the air conveying component 3 to the remote laboratory for testing.

[0035] The feeding box 31 and the outlet box 33 are each equipped with two sets of air duct channels. The sampling bottle 5 containing tobacco samples that enters the feeding box 31 will enter the laboratory through one set of air ducts, while the empty sampling bottle 5 that has been tested in the laboratory will be connected to the outlet box 33 through the other set of air ducts. The empty sampling bottle 5 will fall from the discharge port 34 of the outlet box 33.

[0036] Since the discharge port 34 is located above the limiting cylinder 25, and the center of the discharge port 34 is on the circular movement path of the limiting cylinder 25, the sampling bottle 5 coming out of the discharge port 34 will enter the limiting cylinder 25, and then move with the conveyor chain 21 to the side near the packing machine 1 for sample collection.

[0037] Furthermore, a position sensor 35 is provided on one side of the discharge port 34, and an electromagnetic switch is provided at the outlet of the discharge port 34. When the position sensor 35 detects that the limiting cylinder 25 is close, the electromagnetic switch opens the discharge port 34 to allow the sampling bottle 5 to quickly fall from the discharge port 34 into the limiting cylinder 25.

[0038] The ring conveyor 2 connects the pneumatic conveyor assembly 3 and the packaging machine 1. The staff only needs to load the sample into the packaging machine 1, and the sampling bottle 5 can be sent to the pneumatic conveyor assembly 3 via the ring conveyor 2 and then transferred to the laboratory at the back end for testing. At the same time, the empty sampling bottle 5 is also moved to the vicinity of the staff via the pneumatic conveyor assembly 3 and the ring conveyor 2, which reduces the intensity of personnel work and improves efficiency.

[0039] Furthermore, a reverse fan is provided at the outlet 34. The reverse fan blows air onto the sampling bottle 5 falling from the outlet 34 to reduce the falling speed of the sampling bottle 5 and prevent the sampling bottle 5 from colliding violently with the limiting cylinder 25.

[0040] Furthermore, the base plate 24 is provided with an electric push plate 4 below the opening 26. The opening 26 can be controlled by the electric push plate 4. When it is not necessary to insert the sampling bottle 5, the opening 26 can be blocked by the electric push plate 4.

[0041] Furthermore, the electric push plate 4 is equipped with a pressure sensor. When there is a sample in the sampling bottle 5, the weight of the sampling bottle 5 will push the electric push plate 4, and the electric push plate 4 will open to allow the sampling bottle 5 to enter the delivery port 32. When the sampling bottle 5 is empty, the weight of the sampling bottle 5 cannot push the pressure sensor of the electric push plate 4, and the sampling bottle 5 will be carried by the limiting cylinder 25 to continue to move in a circle, which can prevent the empty bottle from entering the delivery box 31.

[0042] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
