Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and mainly to an automatic sampling device for obtaining cigarette products from the drum of a cigarette machine. Background Technology

[0002] An automatic sampling device is a device that takes samples from the drum of a cigarette rolling machine and delivers them to the online testing instrument's measurement unit for measurement. Typically, the function of an automatic sampling device is to obtain sample cigarettes / filter rods from the cigarette rolling machine and deliver them to the measurement unit for measurement.

[0003] Manual sampling on-site can damage samples due to the experience of the sampling personnel, thus affecting the measurement results. Furthermore, for online equipment, the frequency of sample sampling and inspection is relatively high, and manual sampling would be costly in terms of manpower. Therefore, using an automatic sampling device to obtain samples is a better solution.

[0004] Existing technology CN206683872U discloses a cigarette sampling device and a cigarette conveying line using the same device. The device consists of an inner tube and an outer tube, forming a sampling tube for grabbing cigarettes from a cigarette conveyor belt. The outer tube is a fixed part with a cigarette inlet for the cigarette to enter, while the inner tube is a movable part forming a sealing structure for opening and closing the cigarette inlet. Sampling is performed on the cigarette conveyor belt, relying on the pushing action of the cigarettes from the conveyor belt and subsequent cigarettes to force them into the opening; however, the sampling accuracy is relatively poor.

[0005] The prior art CN216082084U discloses a laser drilling and sampling device for a ZJ17 cigarette machine, including a smoke-discharging wheel, a sampling wheel, and a cigarette. The smoke-discharging wheel is disposed on one side of the sampling wheel. The outer surface of the smoke-discharging wheel is equidistantly arranged with first smoke-receiving grooves along its axial direction. The first smoke-receiving grooves include first sampling grooves, and the number of first sampling grooves is six. One end of the smoke-discharging wheel is provided with a first end cap, and the other end of the smoke-discharging wheel is provided with a first flange. A first drive shaft is disposed at the center of the smoke-discharging wheel, and a first proximity switch is disposed above the first drive shaft. The outer surface of the sampling wheel is equidistantly arranged with second smoke-receiving grooves along its axial direction. The second smoke-receiving grooves include six second sampling grooves. One end of the sampling wheel is provided with a second end cap, and the other end of the sampling wheel is provided with a second flange. A second drive shaft is disposed at the center of the sampling wheel, and a second proximity switch is disposed above the second drive shaft. The cigarette is embedded inside the first smoke-receiving groove and the second smoke-receiving groove. The description only explains the process of the cigarette moving from the cigarette ejector wheel to the sampling wheel. However, it does not disclose the relevant structure for testing such as cigarette weighing, which requires removing the cigarette for subsequent sampling and measurement.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The purpose of this invention is to provide an automatic sampling device for obtaining cigarette products from the drum of a cigarette machine, thereby realizing the automatic acquisition of cigarette samples and improving sampling accuracy.

[0032] Combination Figure 1-2 This utility model provides an automatic sampling device for obtaining cigarette products from the drum of a cigarette machine, including a sampling mechanism, including a sampling wheel 1, which grabs a cigarette from the cigarette outlet wheel and then passes it to the cigarette collection and outlet wheel 3, and a cigarette fork 4 removes the cigarette from the cigarette collection and outlet wheel 3; one end of the cigarette fork is provided with a rotating shaft for adjusting the cutting position of the cigarette fork, and the other end cooperates with the cigarette collection and outlet wheel to fork out the cigarette;

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

[0034] The cigarette receiving mechanism has a sliding channel 8 at the end of the conveying channel, a handle 9 at the bottom of the sliding channel, and a conveyor belt in the middle of the handle. The conveyor belt transports the cigarette to the measuring unit.

[0035] Specifically, in combination Figure 1 Both the sampling wheel 1 and the cigarette extraction wheel 3 are equipped with sample slots 2. Each sample slot 2 has air vents connected to an air source. When grabbing a cigarette, ventilation is directed through the air vents on both sides, and negative pressure is applied to draw air out, thus grabbing the cigarette. In this embodiment, the sample slot 2 has two air vents, each controlled independently. When the two sample slots are connected, the air vents of the cigarette extraction wheel 3 apply negative pressure to draw in the cigarette, while the air vents of the sampling wheel 1 blow the cigarette out, thus grabbing the cigarette.

[0036] Furthermore, in this embodiment, the cigarette is removed from the cigarette dispenser wheel 3 using the cigarette fork 4. Combined with... Figure 3 It can be seen that the cigarette fork 4 has a U-shaped opening, and the cigarette wheel 3 is embedded in the U-shaped opening. When the cigarette wheel 3 rotates to the tangent position of the cigarette fork 4, the wheel continues to rotate counterclockwise. However, because the cigarette fork 4 blocks both ends of the cigarette, under the action of the original inertia and gravity, the cigarette can only roll down along the tangent into the cigarette distribution mechanism channel.

[0037] In the above embodiments, in order for the cigarette fork 4 to block both ends of the cigarette, the length of the cigarette should be greater than the thickness of the cigarette extraction wheel 3. Simultaneously, to prevent only one end of the cigarette from protruding from the cigarette extraction wheel, the cigarette gripping position should be adjusted during the installation of the sampling wheel and the cigarette extraction wheel. In other embodiments, a groove for the cigarette fork to embed can be provided on the cigarette extraction wheel; the groove is two annular grooves.

[0038] Furthermore, in order to ensure a smooth cigarette transport process after sampling, the cigarette conveyor belt 5 is set above the transport channel, and the cigarette conveyor belt 6 is equipped with a stop block 10. The cigarette is limited by the stop block 10 and moves along the transport channel with the stop block under its own weight, which can prevent the cigarette from falling and breaking or being damaged by its own weight.

[0039] Furthermore, in order to simultaneously achieve manual sampling, a flip plate 6 is provided on the conveying channel in this embodiment, combined with... Figure 4 The flip plate 6 has a flip shaft at one end, which is connected to a flip cylinder. The flip cylinder drives the flip shaft to rotate, thereby flipping the flip plate 6, opening the conveying channel, and allowing the cigarettes to fall into the hopper through the flipped notch, thus enabling manual sampling.

[0040] In the above embodiments, in order to prevent the cigarette from breaking during the falling process, an arc-shaped slide 11 is provided below the flip plate 6, and the two sides of the hopper are also arc-shaped, so that the cigarette slides along the arc-shaped side during the falling process.

[0041] Furthermore, the cigarette receiving mechanism is equipped with an inclined sliding channel located at the end of the conveying channel. A cover plate 12 is installed on the inclined sliding channel, and a push-button switch is located on one side of the cover plate to open and close it. After the cigarette slides down the inclined sliding channel, it falls into the handle 9, which is equipped with a conveyor belt. The cigarette is conveyed along the conveyor belt to the measuring unit for measurement. A cover plate is also located above the handle 9, and a push-button switch is located on one side of the cover plate. The measuring unit may be, for example, a weighing unit.

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

[0043] Specific examples of this utility model are provided to illustrate its principles and implementation methods, aiming to help understand the method and core ideas of this utility model. For those skilled in the art, the specific implementation methods and application scope may be adjusted according to the concept of this utility model. Therefore, the content of this specification should not be considered as a limitation of this utility model.
