[0002] In the cigarette production process, the testing of physical parameters is a crucial step in ensuring the stability and consistency of product quality. Common testing parameters include the weight, circumference, length, draw resistance, and hardness of the cigarette, which directly affect the combustion performance, taste, and consumer experience. Therefore, in the quality control process of cigarette manufacturers, it is usually necessary to sample and test finished cigarettes to ensure that their various physical parameters meet national or industry standards.

[0003] Currently, cigarette physical property testing typically employs automated or semi-automated testing equipment, such as integrated testing benches or stand-alone measuring devices. In practice, operators place a certain number of cigarettes (e.g., 30) into the testing equipment and measure various properties for each cigarette sequentially. However, during the automated feeding and dispensing process, problems such as uneven cigarette arrangement, cigarette jamming, and inaccurate dispensing often occur, affecting testing efficiency and accuracy. Especially before the cigarettes enter the weighing unit or other testing modules, if the feeding is not done sequentially, orderly, and stably, it can easily lead to deviations in test data, or even equipment shutdown for adjustments, reducing overall testing efficiency.

[0004] In existing technologies, some testing equipment uses vibratory feeders or rotary dispensing discs for automatic cigarette dispensing and conveying. However, these structures still suffer from problems such as complex structure, high maintenance costs, and poor adaptability in practical applications. Especially when there are many variations in cigarette specifications, existing dispensing devices often require frequent adjustments or replacements of parts to adapt to different specifications of cigarettes, which is inconvenient to operate and affects the continuous operation and production efficiency of the equipment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The following is combined Figures 1-3 This invention describes the specific implementation of the tobacco hopper and the tobacco distribution and weighing device of this utility model.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a cigarette hopper, comprising: a hopper disposed above a weighing unit, the hopper including a vertical plate 11 and an inclined plate 12, the inclined plate 12 being inclined relative to the horizontal plane to form an acute angle with the vertical plate 11, cigarettes placed in the hopper rolling along the inclined plate 12 and close to the vertical plate 11 under the action of gravity; a reciprocating plate 13, which can move up and down along the height direction of the vertical plate 11 on the inner side of the vertical plate 11 under the drive of a power source, the reciprocating plate 13 being provided with an inclined outlet 131, when the height of the inclined outlet 131 is lower than the top of the vertical plate 11, the inclined outlet 131 forms a lifting groove on the inner side of the vertical plate 11 that can accommodate a cigarette, when the height of the inclined outlet 131 is higher than the top of the vertical plate 11, the cigarette lifted by the lifting groove can be discharged through the inclined outlet 131; and a limiting plate 14 disposed on the outer side of the vertical plate 11, used to limit the falling trajectory of the cigarette discharged from the inclined outlet 131 and guide it to the weighing unit.

[0026] Specifically, the cigarette hopper uses an inclined plate 12 that works in conjunction with a vertical plate 11 to allow cigarettes to automatically gravitate towards the vertical plate 11 under gravity, achieving initial neat arrangement. A reciprocating plate 13, driven by a power source (such as a cylinder or motor), moves up and down along the inner side of the vertical plate 11. Its inclined outlet 131 engages with the vertical plate 11 at different positions, forming a lifting groove capable of accommodating individual cigarettes, thus achieving cigarette-by-cigarette lifting and distribution. When the reciprocating plate 13 rises until the inclined outlet 131 is higher than the top of the vertical plate 11, the cigarette is pushed out of the inclined outlet 131 and, guided by a limiting plate 14, accurately falls into the receiving basket of the weighing unit, completing the orderly conveying and weighing of the cigarettes.

[0027] In use, the aforementioned cigarette hopper is installed above the weighing unit. The operator places the cigarettes to be tested into the hopper in batches. Under the influence of gravity, the cigarettes slide down the inclined plate 12 and adhere to the vertical plate 11, forming a neat arrangement. Subsequently, driven by the power source, the reciprocating plate 13 begins to move up and down. When the reciprocating plate 13 moves downwards, the inclined outlet 131 is lower than the top of the vertical plate 11, and the cigarettes enter the lifting trough. When the reciprocating plate 13 moves upwards, the lifting trough carries a cigarette to above the inclined outlet 131, from which the cigarette is discharged. Under the limiting and guiding action of the limiting plate 14, it falls into the V-shaped receiving basket of the weighing unit, where the weighing host completes the weight detection. This process is repeated cyclically, achieving individual distribution and automatic weighing of cigarettes, suitable for scenarios such as continuous testing of 30 cigarettes.

[0028] Furthermore, the bottom of the hopper preferably adopts a concealed design, not protruding outwards, so that the weighing unit below is fully exposed, facilitating routine calibration, maintenance, or troubleshooting of the weighing host. Simultaneously, the limiting plate 14 or other mechanisms can support the cigarettes during discharge, reducing their falling height and thus minimizing tobacco and dust loss, improving the cleanliness of the testing environment. In addition, this cigarette hopper has a compact structure and high modularity, allowing for easy integration into cigarette testing benches or other physical property testing equipment. It possesses good versatility and portability, suitable for testing different cigarette sizes.

[0029] According to the present invention, a cigarette hopper includes a bottom gap between the inclined plate 12 and the vertical plate 11, allowing the bottom end of the reciprocating plate 13 to enter. This gap is designed so that when the reciprocating plate 13 is at its lowest position, the lifting groove formed by the inclined outlet 131 on the inner side of the vertical plate 11 is located at the lowest position of the hopper. The hopper also includes a roller 16 and a steel belt 15. One end of the steel belt 15 is connected to the roller 16, and the other end is connected to the bottom end of the reciprocating plate 13. The steel belt 15 moves with the up-and-down movement of the reciprocating plate 13. During the upward movement of the reciprocating plate 13, the steel belt 15 prevents other cigarettes from falling out through the bottom gap. The bottom gap between the inclined plate 12 and the vertical plate 11 is designed to allow the bottom end of the reciprocating plate 13 to pass through it during its up-and-down movement. When the reciprocating plate 13 is at its lowest position, the inclined outlet 131 is also at its lowest position. At this time, the lifting groove formed on the inner side of the vertical plate 11 is located precisely in the bottom area of ​​the hopper, facilitating the accurate retrieval of a cigarette from the cigarette pile and the start of upward lifting.

[0030] To prevent cigarettes from falling through the bottom gap during the material distribution process, which could cause smoke leakage, jamming, or affect the accuracy of subsequent testing, this invention further includes a drag wheel 16 and a steel belt 15. One end of the steel belt 15 is connected to the drag wheel 16, and the other end is fixed to the bottom end of the reciprocating plate 13. As the reciprocating plate 13 moves up and down inside the vertical plate 11, the steel belt 15 also moves accordingly. When the reciprocating plate 13 rises, the steel belt 15 is driven to move upward synchronously and covers the bottom gap, forming a temporary smoke barrier. This effectively prevents other unlifted cigarettes from falling through or getting stuck in the bottom gap, ensuring that only one cigarette is carried out by the lifting groove, thereby improving the accuracy and stability of the material distribution.

[0031] Furthermore, according to a tobacco hopper of this utility model, the steel belt 15 is provided with mesh holes for screening fallen tobacco shreds and dust outside the hopper. During the up-and-down movement of the steel belt 15 driven by the reciprocating plate 13, some tobacco shreds may fall off or tobacco dust may scatter due to stress or during rolling and lifting. The mesh structure on the steel belt 15 can filter these fine particles as the steel belt 15 moves, allowing tobacco shreds and dust to fall through the mesh holes to the collection area outside the hopper in a timely manner, keeping the inside of the hopper clean and reducing problems such as tobacco jamming and poor material distribution caused by the accumulation of foreign objects. At the same time, it also helps maintain the stable operation of the weighing unit, avoids impurities interfering with the weight detection results, and improves the overall accuracy of detection and the stability of equipment operation.

[0032] Furthermore, according to the present invention, a fume hopper also includes a hidden box 17 disposed below the inclined plate 12; the hidden box 17 has a hidden space for accommodating the towing wheel 16 and the steel belt 15; at least two limiting roller shafts 171 are also provided in the hidden space to restrict the movement of the towing wheel 16 and the steel belt 15 along a fixed trajectory within the hidden space. The function of the at least two limiting roller shafts 171 in the hidden space is to guide and restrict the movement trajectory of the towing wheel 16 and the steel belt 15 within the hidden box 17, ensuring that the steel belt 15 always runs smoothly along a set path during the up-and-down movement of the reciprocating plate 13, avoiding problems such as deviation, jamming, or abnormal friction, thereby improving the stability and service life of the transmission system. The limiting roller shafts 171 also support the steel belt 15 and reduce running resistance, making the steel belt 15 more flexible and smooth during lifting and lowering. In addition, the design of the hidden box 17 is also conducive to the daily cleaning and maintenance of the equipment. Operators can clean the hidden box 17 regularly to prevent the accumulation of tobacco shreds and dust from affecting the transmission performance, and further ensure the reliability and stability of the tobacco hopper during long-term continuous operation.

[0033] To further improve the stability and guiding accuracy of the reciprocating plate 13 during its up-and-down movement, the present invention provides a cigarette hopper that further includes a mounting plate 18 and a guide rail 181. The mounting plate 18 is provided with a track seat 182, and the guide rail 181 is mounted on the reciprocating plate 13 for sliding engagement with the track seat 182 to limit the movement trajectory of the reciprocating plate 13. This sliding engagement between the guide rail 181 and the track seat 182 provides stable guidance when the reciprocating plate 13 is driven up and down by a power source, ensuring that its movement trajectory remains in the set vertical direction and avoiding inaccurate cigarette dispensing or unstable equipment operation due to offset, shaking, or jamming. Simultaneously, this guiding structure effectively improves the repeatability and positioning accuracy of the reciprocating plate 13, thereby improving the reliability and efficiency of cigarette dispensing. Preferably, the track seat 182 may contain a ball bearing or roller structure to reduce the frictional resistance between the guide rail 181 and the track seat 182, making the movement of the reciprocating plate 13 smoother and extending the service life of the components. In addition, the guide structure is preferably designed as a detachable structure that is easy to disassemble and maintain, which is beneficial to the long-term stable operation of the equipment.

[0034] According to a cigarette hopper of this utility model, a limiting plate 14 is fixedly mounted on an mounting plate 18, and a structural gap 141 with a size at least larger than the diameter of the cigarette is provided between the limiting plate 14 and the vertical plate 11. The size of this structural gap 141 is at least larger than the diameter of the cigarette to ensure that the cigarette discharged from the inclined outlet 131 can fall smoothly in the gap between the limiting plate 14 and the vertical plate 11. Simultaneously, the limiting plate 14 effectively constrains and guides the falling path of the cigarette, preventing the cigarette from deviating, getting stuck, or tilting during discharge. Specifically, the design of the limiting plate 14 not only limits and guides the falling trajectory of the cigarette but also prevents the cigarette from flying off the predetermined path due to external force or inertia during transport, thereby improving the stability and reliability of cigarette transport.

[0035] Furthermore, according to the present invention, a tobacco hopper also includes a tobacco holder 132; the tobacco holder 132 is fixed to the reciprocating plate 13 and extends through the vertical plate 11 into the structural joint 141. The vertical plate 11 is provided with a vertical slot (not shown in the figure) to allow the tobacco holder 132 to move up and down with the reciprocating plate 13; when the height of the inclined outlet 131 is higher than the top of the vertical plate 11, the cigarettes lifted by the lifting groove can be discharged through the inclined outlet 131 to fall into the structural joint 141 and be supported by the tobacco holder 132; the tobacco holder 132 can support the cigarettes as they descend with the reciprocating plate 13 until the cigarettes fall towards the weighing unit. Specifically, the tobacco holder 132 is fixedly connected to the reciprocating plate 13 and extends through the vertical slot on the vertical plate 11 into the structural joint 141 between the limiting plate 14 and the vertical plate 11. When the reciprocating plate 13 moves up and down under the drive of the power source, the tobacco holder 132 moves synchronously. When the inclined outlet 131 rises above the top of the vertical plate 11, the cigarettes located in the lifting groove are pushed out of the inclined outlet 131 and fall into the structural joint 141, where they are supported by the cigarette holder 132. Driven by the reciprocating plate 13, the cigarette holder 132 begins to move downwards, and the cigarettes descend with it until they reach the set position, after which they fall smoothly from the cigarette holder 132 into the V-shaped receiving basket of the weighing unit, completing one cigarette distribution and weighing process. This design of the cigarette holder 132 effectively avoids the problem of tobacco falling off or cigarettes being damaged due to excessive height difference after exiting the inclined outlet 131.

[0036] Furthermore, according to a cigarette hopper of this utility model, the limiting plate 14 includes a deformable portion 142, which is located at the lower end of the limiting plate 14, and the width of the structural seam 141 at the deformable portion 142 is greater than the width of the structural seam 141 above it. Specifically, the width of the structural seam 141 at the upper part of the limiting plate 14 matches the load-bearing capacity of the cigarette holder 132, providing limiting guidance during the process of the cigarette being carried down by the cigarette holder 132, preventing the cigarette from accidentally falling before release; while the width of the structural seam 141 at the deformable portion 142 is larger, providing a suitable falling channel for the cigarette after it is released from the cigarette holder 132, allowing the cigarette to fall smoothly into the weighing unit, while the widened area does not cause the falling trajectory of the cigarette to deviate too much, thus playing a dual role of limiting and guiding.

[0037] Furthermore, according to a tobacco hopper of this utility model, when the reciprocating plate 13 is moved to its highest position, the inclined outlet 131, the top of the vertical plate 11, and the tobacco holder 132 are aligned to form an inclined surface. Specifically, this inclined surface structure provides a smooth transition path for the cigarette to slide smoothly out of the lifting groove and into the structural seam 141, avoiding obstruction or jamming of the cigarette during discharge, thereby ensuring that the cigarette can smoothly slide onto the tobacco holder 132.

[0038] This utility model also provides a cigarette distribution and weighing device. The cigarette distribution and weighing device provided by this utility model is described below. The cigarette distribution and weighing device described below can be referred to in correspondence with the cigarette hopper described above.

[0039] The cigarette distribution and weighing device includes a weighing unit and a cigarette hopper as described in the above embodiment. The weighing unit includes a weighing host and a V-shaped receiving basket. The V-shaped receiving basket is mounted on the weighing host and is used to receive the cigarettes distributed by the cigarette hopper. The weighing host detects weight changes. This cigarette distribution and weighing device separates and transports cigarettes one by one in an orderly manner through the cigarette hopper, and accurately places the cigarettes into the V-shaped receiving basket of the weighing unit in sequence, thereby achieving continuous and automatic detection of cigarette weight. After the weight of each cigarette is detected, the V-shaped receiving basket can perform a cigarette discharge action to ensure that the detected cigarettes can be smoothly discharged from the weighing unit, making room for the next cigarette or the next group of cigarettes to be detected. Specifically, once a testing cycle is completed, the weighing host can be set to drive the V-shaped receiving basket to exhaust smoke (for example, a mechanism to exhaust smoke can be used by changing the posture of the V-shaped receiving basket with a pneumatic push rod or a rotary drive), causing the cigarettes that have been measured to be removed from the V-shaped receiving basket and enter the subsequent processing stage (such as sorting, packaging, etc.).

[0040] In actual operation, the cigarette hopper is installed above the weighing unit. The operator puts a group of cigarettes (e.g., 30 cigarettes) into the hopper. Initially, the reciprocating plate 13 is at the bottom of the hopper. Driven by a power source (e.g., a motor or cylinder), the reciprocating plate 13 begins to rise slowly, moving the cigarettes upwards and distributing them one by one through the inclined outlet 131. When the inclined outlet 131 rises above the top of the vertical plate 11, only one cigarette enters the lifting groove and is pushed out of the inclined outlet 131, then slides down into the structural seam 141 between the cigarette holder 132 and the limiting plate 14, where it is supported by the cigarette holder 132.

[0041] As the reciprocating plate 13 continues to rise, the steel belt 15, driven by the towing roller 16, moves upward and to the right, filling the space below the reciprocating plate 13 and preventing the remaining cigarettes from falling through the bottom gap, ensuring the stability and accuracy of the material distribution process. Subsequently, the reciprocating plate 13 begins to descend under the power source, and the steel belt 15 drives the towing roller 16 to move to the left, while the cigarette holder 132 carries the cigarettes downward in sync. When the cigarette holder 132 descends to its lowest position, the cigarettes fall smoothly from the cigarette holder 132 into the V-shaped receiving basket below, where the weighing host completes a weight check.

[0042] The process is continuously repeated with the reciprocating motion of the reciprocating plate 13, realizing continuous dispensing and weighing of cigarettes one by one. The cooperative structure of the cigarette holder 132 and the limiting plate 14, the anti-drop design of the steel belt 15 and the towing wheel 16, and the protection of the transmission components by the hidden box 17, among other structural features, enable the entire cigarette dispensing and weighing device to have high stability, high precision, and good automation performance.

[0043] This device is compact in structure and easy to maintain. It is suitable for the testing needs of cigarettes of different specifications and has strong versatility and portability. It can be widely used in the physical index testing process of cigarette manufacturing enterprises, effectively improving testing efficiency and quality control level.
