DETAILED DESCRIPTION

[0030] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present disclosure, its application, or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of parts and steps, the composition of materials, numerical expressions, and numerical values ​​set forth in these embodiments should be interpreted as being merely exemplary and not as limiting.

[0031] The terms "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different parts. The terms "include" or "comprises" and similar terms mean that the elements before the term include the elements listed after the term, and do not exclude the possibility of also including other elements. The terms "upper", "lower", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] In the present disclosure, when a specific device is described as being located between a first device and a second device, an intervening device may or may not be present between the specific device and the first device or the second device. When a specific device is described as being connected to another device, the specific device may be directly connected to the other device without an intervening device, or may be not directly connected to the other device but with an intervening device.

[0033] All terms (including technical or scientific terms) used in this disclosure have the same meaning as understood by one of ordinary skill in the art to which this disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined as such herein.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0035] Based on the above-mentioned embodiments of the present disclosure, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

[0036] During the research, the inventors found that when the material flow is stable and uniform, the moisture meter can continuously and accurately detect the moisture content in the material, and the temperature meter can continuously and accurately detect the material temperature. In this case, the standard deviation of the measurement results is low, reflecting the consistency and accuracy of the measurement data. However, the material flow on the production line vibration trough fluctuates greatly, and the material distribution conditions often seen are as follows: Figure 1 shown.

[0037] When the material flow rate decreases, causing the material layer to become thinner or the material to break, the moisture meter and / or temperature meter may not be able to fully contact or evenly detect the material surface, resulting in a decrease in measurement accuracy. A material layer that is too thin or broken may also cause large fluctuations in the measurement data, increasing measurement errors and standard deviation.

[0038] When material flow is extremely low or even sees a bottom plate, moisture meters and / or temperature meters may fail to detect the material, resulting in missing data or distorted measurements. This not only affects the continuity and integrity of the measurement but can also mislead production personnel about the material's moisture and temperature. This bottom plate condition can also cause production personnel to misjudge the material's moisture and temperature status, affecting parameter adjustments in subsequent processing steps and product quality control.

[0039] To solve at least one of the above problems, firstly, the present disclosure proposes a material conveying system, such as Figures 2 to 4 As shown, including:

[0040] A conveying component 1 extends along a first direction x and conveys a material 100 along the first direction x;

[0041] A flow guide assembly 2 is provided on the conveying component 1, and includes a first flow guide section 21 and a second flow guide section 22, wherein the second flow guide section 22 is connected downstream of the first flow guide section 21, and along the first direction x, the conveying width of the first flow guide section 21 along the second direction y gradually decreases, and the conveying width of the second flow guide section 22 along the second direction y remains unchanged, and the second direction y is perpendicular to the first direction x; and

[0042] The detection component 3 is provided above the second guide section 22 , and is configured to detect the moisture content and / or temperature of the material 100 .

[0043] Specifically, the conveying channel of the first guide section 21 is a constriction, and the conveying speed of the conveying component 1 along the first direction x of the material 100 is constant. The conveying width of the first guide section 21 along the second direction y gradually decreases, so that the material height in the first guide section 21 along the third direction z gradually increases, prompting the material 100 to accumulate naturally during the conveying process, creating favorable conditions for subsequent detection. The third direction z is perpendicular to the first direction x and the second direction y.

[0044] Specifically, the conveying channel of the second guide section 22 has a constant width, which can stabilize the material flow and reduce the thickness fluctuation of the material 100 along the Z direction. The second guide section 22 is located after the first guide section 21 and is the area where the material height reaches the maximum. It can ensure that the material forms a stable and uniform material layer here, facilitating accurate measurement by a moisture meter and / or temperature meter. Specifically, the detection component 3 is mounted on the fixed bracket 31.

[0045] Specifically, the flow guide assembly 2 adjusts the height and distribution of the material 100 during transport. This ensures a stable and sufficient supply of material within the detection area of ​​the moisture meter and / or temperature meter, even when the material flow is uneven, thereby significantly improving measurement accuracy and stability. A moderate material thickness helps the moisture meter detect the moisture and / or temperature on the material surface stably and evenly, reducing measurement errors caused by excessive thickness fluctuations.

[0046] Specifically, assuming the instantaneous flow rate of material 100 is F, the thickness of its material layer is h0, and the flow rate fluctuation is ΔF, the relationship between the material layer thickness H at the second guide section 22 and the instantaneous flow rate F can be expressed as H = h0 + aΔF, where h0 is the base height and a is the growth coefficient related to material flow fluctuation. The above analysis shows that maintaining a stable material layer thickness of the tobacco material in the second guide section 22 facilitates stable and uniform detection of moisture and / or temperature on the material surface, reducing measurement errors caused by excessive fluctuations in the material layer thickness.

[0047] Alternatively, the material 100 can be any material, such as tobacco. Alternatively, the conveying component 1 can be a vibrating conveyor trough or conveyor belt, the flow guide assembly can include a flow guide plate or a flow guide wall, and the detection component 3 can include a moisture meter and / or a temperature meter. Optionally, by adjusting the length and shape of the first flow guide section 21 or the second flow guide section 22, the height and distribution of the material 100 can be further optimized to meet measurement requirements at different material flow rates.

[0048] The material conveying system of this embodiment has a simple and reliable structure and is convenient for modification on the basis of an existing production line. The first guide section 21 of the guide assembly 2 can effectively concentrate the material 100, and the second guide section 22 can stabilize the flow of the material and the thickness of the material in the Z direction, so that the thickness and continuity of the material 100 are guaranteed, and the accuracy of the moisture detection and / or temperature detection of the material can be improved; by improving the accuracy of the detection results, unnecessary equipment parameter adjustments and maintenance caused by detection errors by operators can be reduced, the quality of cigarette shreds can be effectively guaranteed, the cigarette production efficiency can be improved, and the comprehensive efficiency index of the equipment in the cigarette production workshop can be improved.

[0049] In some embodiments, the detection point 30 of the detection component 3 is located in the central area of ​​the second guide segment 22 along the second direction y.

[0050] The detection point 30 of this embodiment is located in the central area of ​​the second guide section 22 along the second direction y, or in other words, the detection point 30 is located at the midpoint or near the midpoint of the second guide section 22 along the second direction y. The highest part of the material 100 can be selected for detection, thereby reducing the impact of poor height stability in the edge area and improving the reliability and accuracy of the detection results.

[0051] In some embodiments, as Figure 2 As shown, the guide assembly 2 further includes a third guide segment 23 , which is connected downstream of the second guide segment 22 . Along the first direction x, the conveying width of the third guide segment 23 gradually increases along the second direction y.

[0052] Specifically, the third guide section 23 is connected to the detection position of the second guide section 22 , and its shape is a gradually outwardly expanding form.

[0053] After the detection component 3 completes the detection, the material 100 of this embodiment passes through the gradually expanding third guide section 23, which can ensure that the material continues to flow smoothly without accumulation or blockage, thereby improving the looseness of the material.

[0054] In some embodiments, as Figure 2 As shown, the conveying width at the inlet of the first guide section 21 is equal to the conveying width at the outlet of the third guide section 23 .

[0055] The material of this embodiment can be restored to the conveying width of the original conveying component after the detection is completed, which can ensure that the width of the inlet and outlet of the material 100 remains consistent during the entire conveying process, facilitating reliable connection with downstream equipment.

[0056] In some embodiments, the conveying speed of the conveying component 1 along the first direction x is the same at the first guiding section 21, the second guiding section 22, and the third guiding section 23. Optionally, the conveying speed of the conveying component 1 at each guiding section may also be different.

[0057] In some embodiments, the conveying width of each guide section of the guide assembly 2 is adjustable.

[0058] In some embodiments, the guide assembly 2 is detachable relative to the conveying component 1, and there are multiple guide assemblies 2. The conveying width of the second guide section 22 of each guide assembly 2 along the second direction y is different, and the material conveying system can selectively install a conveying component 1 that is adapted to the material flow rate.

[0059] This embodiment can precisely control materials with different flow rates by replacing different flow guide components 2, ensuring uniform distribution and stable flow of materials during transportation; the modular design can also simplify maintenance and replacement operations, reducing cigarette production costs.

[0060] In some embodiments, as Figure 3 and Figure 4 As shown, the conveying component 1 includes a first side plate 11, a second side plate 12, and a bottom plate 13. The first side plate 11 and the second side plate 12 are arranged relative to each other along the second direction y, and the bottom plate 13 is connected between the first side plate 11 and the second side plate 12. The guide assembly 2 includes a first guide plate 201 and a second guide plate 202. The first guide plate 201 is connected between the first side plate 11 and the bottom plate 13, and the second guide plate 202 is connected between the second side plate 12 and the bottom plate 13. Optionally, the first side plate 11 and the second side plate 12 can be straight plates or curved plates.

[0061] The first guide plate 201 and the second guide plate 202 of this embodiment guide the material 100 from both sides respectively, which can reduce the fluctuation amplitude of the conveying thickness of the material 100 and avoid material breakage; the guide plate structure is easy to disassemble and maintain, and can be flexibly adjusted according to different production needs, such as adjusting the angle between the guide plate and the bottom plate, the lowest point distance between the first guide plate 201 and the second guide plate 202, etc. according to the flow rate of the material.

[0062] In some embodiments, the first guide plate 201 and the second guide plate 202 are preferably arranged symmetrically.

[0063] In some embodiments, the bottom plate 13 is provided with a fixing groove, and the inner sides of the first and second side plates 11 and 12 are provided with quick connectors, and the first and second deflector plates 201 and 202 are installed between the fixing groove and the quick connector. Optionally, the quick connectors on the inner sides of the first and second side plates 11 and 12 can be quick-connect buckles, etc.

[0064] The fixing groove and quick interface of this embodiment can improve the efficiency of disassembly and assembly of the guide plate, facilitate the adjustment of the angle of the guide plate according to different material flows, and improve the adaptability and pertinence of the material conveying system.

[0065] In some embodiments, as Figure 3 As shown, the first guide plate 201 and the second guide plate 202 are both straight plates.

[0066] The acute angle between the first guide plate 201 and the bottom plate 13 is 10° to 90°; and / or

[0067] The acute angle between the second guide plate 202 and the bottom plate 13 is 10° to 90°.

[0068] The guide plate of this embodiment is a straight plate, which can reduce production costs; the angle range of 10° to 90° can not only ensure the smooth flow of materials, but also effectively concentrate the material flow, avoiding the formation of dead corners or accumulation of materials between the guide plate and the bottom plate; by adjusting the inclination angle of the guide plate, the width of the conveying channel of each guide section can also be adjusted, reducing the fluctuation amplitude of the conveying thickness of the material 100 and avoiding material breakage, thereby adapting to the flow and detection requirements of different materials on the production line.

[0069] In some embodiments, as Figure 4 As shown, in the second guide section 22,

[0070] The first guide plate 201 is an arc-shaped plate that protrudes away from the bottom plate 13; and / or

[0071] The second guide plate 202 is an arc-shaped plate that protrudes away from the bottom plate 13 .

[0072] The guide plate of this embodiment protrudes in the direction away from the bottom plate 13 in the second guide section 22. When the material flow rate decreases, it can improve the material concentration efficiency compared to the straight plate, quickly increase the thickness of the material layer, avoid the material layer from becoming thinner or breaking, and reduce the irregular distribution of the material; when the material flow rate increases, it can quickly disperse the material in the y direction compared to the straight plate, reduce the increase in the material layer thickness in the z direction, thereby reducing the fluctuation amplitude of the material layer thickness caused by material flow fluctuations, and improve the detection accuracy of the material moisture and / or temperature.

[0073] Secondly, the present disclosure also proposes a cigarette production device, including the material conveying system of the above embodiment.

[0074] The cigarette production equipment of this embodiment has high accuracy in material moisture or temperature detection, reduces unnecessary equipment parameter adjustments and maintenance by operators due to detection errors, improves cigarette tobacco quality and cigarette production efficiency, and can improve the overall equipment efficiency index of the cigarette production workshop.

[0075] The above provides a detailed introduction to the material conveying system and cigarette production equipment provided by the present disclosure. Specific examples are used herein to illustrate the principles and implementation methods of the present disclosure. The description of the above examples is intended only to facilitate understanding of the method and core concepts of the present disclosure. It should be noted that those skilled in the art may make various improvements and modifications to the present disclosure without departing from the principles of the present disclosure, and such improvements and modifications fall within the scope of protection of the claims of the present disclosure.
