[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide an automatic sampling device for obtaining cigarette products from a cigarette making machine drum, so as to realize the automatic acquisition of cigarette sampling process and improve the sampling accuracy.

[0032] Combination Figure 1-2 The present invention provides an automatic sampling device for obtaining cigarette products from a cigarette making machine drum, comprising a sampling mechanism, including a sampling wheel 1, the sampling wheel 1 grabs a cigarette from a cigarette outlet wheel, and then passes it to a cigarette taking and outlet wheel 3, and a cigarette taking fork 4 takes the cigarette from the cigarette taking and outlet wheel 3;

[0033] The cigarette sorting mechanism includes a cigarette conveyor belt 5. After the cigarette fork 4 takes out the cigarette, the cigarette falls onto the online detection conveyor belt along the conveying channel under the action of the cigarette conveyor belt 5. A turning piece 6 is arranged on the conveying channel, and a hopper 7 is arranged below the turning piece 6.

[0034] The cigarette receiving mechanism has a sliding channel 8 at the end of the conveying channel, a support hand 9 is provided at the bottom of the sliding channel, and a conveyor belt is provided in the middle of the support hand, and the conveyor belt conveys the cigarettes to the measuring unit.

[0035] Specifically, combined Figure 1 The sampling wheel 1 and the smoke-taking and smoke-discharging wheel 3 are both provided with a sample slot 2, and the sample slot 2 is provided with air holes, which are connected to the air source. When grabbing a cigarette, ventilation and negative pressure suction are respectively directed to the air holes on both sides to achieve grabbing of the cigarette. In this embodiment, there are two air holes in the sample slot 2, and the air holes of each sample slot are controlled separately. When the two sample slots are connected, the air holes of the smoke-taking and smoke-discharging wheel 3 suck the cigarette with negative pressure, and the air holes of the sampling wheel 1 are ventilated to blow the cigarette out, thereby achieving the grabbing of the cigarette.

[0036] Furthermore, in this embodiment, the cigarette is taken out from the cigarette taking and discharging wheel 3 by the cigarette taking fork 4. Figure 3 It can be seen that the cigarette fork 4 has a U-shaped opening, and the cigarette sampling and smoke discharging wheel 3 is embedded in the U-shaped opening. When the sampling and smoke discharging wheel 3 rotates to the tangent position of the cigarette fork 4, the wheel continues to rotate counterclockwise, and the cigarette can only roll down into the smoke separation mechanism channel along the tangent due to the original inertia and gravity because the cigarette fork 4 blocks both ends of the cigarette.

[0037] In the above embodiment, in order to achieve that the cigarette fork 4 can block both ends of the cigarette, the length of the cigarette should be greater than the thickness of the cigarette extraction and smoke discharge wheel 3. At the same time, in order to ensure that only one end of the cigarette is prevented from extending out of the cigarette extraction and smoke discharge wheel, the cigarette grabbing position should be adjusted when installing the sampling wheel and the cigarette extraction and smoke discharge wheel. In other embodiments, a groove for the cigarette extraction fork to be embedded can be opened on the cigarette extraction and smoke discharge wheel, and the groove is two annular grooves.

[0038] Furthermore, in order to control the smooth conveying process of cigarettes after sampling, the cigarette conveyor belt 5 is arranged above the conveying channel, and the cigarette conveyor belt 6 is provided with a block 10 on it. The cigarettes are limited by the block 10 and move on the conveying channel with the block under the action of their own weight, which can prevent the cigarettes from falling, scattering or being damaged directly due to their own weight.

[0039] Furthermore, in order to realize manual sampling at the same time, a flip sheet 6 is provided on the conveying channel in this embodiment. Figure 4 A flip shaft is provided at one end of the flip sheet 6, and the flip shaft is connected to the flip cylinder. The flip cylinder drives the flip shaft to rotate, so that the flip sheet 6 is flipped, the conveying channel is opened, and the cigarette falls into the hopper along the notch after flipping, realizing manual sampling.

[0040] In the above embodiment, in order to ensure that the cigarettes will not be damaged during the falling process, an arc-shaped slide 11 is provided under the flip plate 6, and the two sides of the hopper are also arc-shaped, so that the cigarettes slide along the arc-shaped sides during the falling process.

[0041] Furthermore, the cigarette receiving mechanism is provided with an oblique sliding channel, which is arranged along the end of the conveying channel. A cover plate 12 is provided on the oblique sliding channel, and a push switch is provided on one side of the cover plate to realize the opening and closing of the cover plate. After the cigarette slides down through the oblique sliding channel, it falls into the support hand 9, and a conveyor belt is provided in the support hand. The cigarette is transported to the measuring unit along the conveyor belt for measurement. A cover plate is also provided above the support hand 9, and a push switch is provided on one side of the cover plate. The measuring unit is, for example, a weighing unit.

[0042] This specification describes various embodiments in a progressive manner, and emphasizes the differences between each embodiment and other embodiments. The same or similar parts in various embodiments are referenced to each other.

[0043] The specific examples of the present invention are used to illustrate its principles and implementation methods, and are intended to help understand the methods and core ideas of the present invention. For those skilled in the art, according to the concepts of the present invention, the specific implementation methods and application scopes may be adjusted. Therefore, the contents of this specification should not be regarded as limiting the present invention.
