Description

Technical Field

[0001] This utility model belongs to the field of cigarette butt information collection technology, and in particular relates to a device for dispersing piled cigarette butts. Background Technology

[0002] To accurately obtain information about cigarette consumers' smoking habits and preferred product styles, existing technologies have developed methods for determining smoking behavior based on cigarette butt image information collection. For example, the Chinese invention patent application CN117496186A disclosed by this applicant discloses a method and apparatus for determining smoking behavior based on cigarette butt images. This method collects image information of cigarette butts after smoking and finished cigarettes, then compares the cigarette butt images with the finished cigarette images, and determines the remaining length of various types of cigarettes after smoking based on the image information comparison. It then calculates the proportion of the remaining length of the cigarette to the total length of the finished cigarette pack for that type. Based on this proportion, the smoking behavior of each brand and specification of cigarette can be determined, thus providing direction and ideas for subsequent product development and maintenance.

[0003] Another example is the method and apparatus for determining the puff capacity based on cigarette butt images disclosed in the applicant's Chinese invention patent application with publication number CN117496233A. This method is based on the discovery that there are differences in the color of cigarette butt filter cross-section images under different puff capacities. It constructs an image classification model, uses cigarette butt filter cross-section images under different puff capacities as training data to train the image classification model, and then inputs the collected cigarette butt filter cross-section image data after puffing into the trained classification model to obtain the puff capacity of the cigarette butt after puffing, providing direction and ideas for subsequent product development and maintenance.

[0004] Both methods for determining cigarette consumers' smoking behavior mentioned above require image collection of cigarette butts after smoking. This necessitates collecting cigarette butts from various public smoking areas and processing the collected batches of butts by removing impurities, dispersing, and orienting them. This process separates impurities, increases the distance between cigarette butts, and straightens their orientation to ensure they don't obstruct each other during image acquisition. This facilitates the acquisition of cross-sectional images of the cigarette butt filter rods, improving the quality of the acquired images and thus increasing the efficiency of comparing cigarette butt images with finished cigarette images. However, current technology lacks a dedicated device for dispersing cigarette butts. Manual methods are not only inefficient but may also cause deformation of the cigarette butts during dispersion due to human factors, leading to distorted images and hindering comparison with finished cigarette images. Utility Model Content

[0005] The purpose of this invention is to provide a device for dispersing piled cigarette butts, so as to solve the technical problems of low dispersing efficiency and easy deformation of cigarette butts in existing devices.

[0006] To achieve the above objectives, the technical solution of the pile cigarette butt dispersion device provided by this utility model is as follows:

[0007] A device for dispersing piled cigarette butts includes two horizontally spaced rollers. The radial distance between the two rollers in the horizontal direction forms a cigarette butt channel through which only a single cigarette butt can pass. A conveyor belt is provided below the rollers so that the piled cigarette butts are dispersed through the cigarette butt channel and fall onto the conveyor belt in a dispersed state for continued transport by the conveyor belt.

[0008] This invention is a pioneering creation, and its beneficial effects are as follows: By constructing a cigarette butt channel suitable for the passage of a single cigarette butt through two rollers, the cigarette butt channel is adapted to the diameter of the cigarette butt in the radial direction, avoiding deformation of the cigarette butt during dispersion; the constructed cigarette butt channel enables continuous dispersion of piled cigarette butts, and the dispersed cigarette butts are kept in a dispersed state by a conveyor belt and directly and continuously transported to the next process of cigarette butt image acquisition, which greatly improves the efficiency of cigarette butt dispersion and facilitates subsequent cigarette butt image acquisition.

[0009] As a further improvement, the cigarette butt dispersing device also includes a tangential baffle located above the two rollers, the distance from the tangential baffle to the roller surface being smaller than the diameter of the dispersed cigarette butts, to prevent the cigarette butts from escaping tangentially along the rollers.

[0010] As a further improvement, the intersection point of the bottom extension line of the tangential baffle and the corresponding roller is located at the highest point of the roller or inside the highest point of the roller.

[0011] As a further improvement, the two rollers rotate in opposite directions, with the side of the two rollers that are close to each other rotating upwards, so that the cigarette butt tends to move upwards.

[0012] As a further improvement, a ramp is installed below the two rollers and at the beginning of the conveyor belt to guide the cigarette butts onto the conveyor belt.

[0013] As a further improvement, the conveyor belt is connected to a vibration mechanism for driving the belt surface to vibrate, so that the cigarette butts bounce on the belt surface.

[0014] As a further improvement, axial guard plates are provided at both ends of the roller to prevent cigarette butts from escaping along the axial direction of the roller.

[0015] As a further improvement, the conveyor belt has multiple dispersion grooves arranged at intervals along the conveying direction of the conveyor belt for cigarette butts to enter, and the width direction of the dispersion grooves is parallel to the conveying direction of the conveyor belt, so as to regulate the orientation of the cigarette butts on the conveyor belt.

[0016] As a further improvement, a height limiter is installed on the conveyor belt, and the distance from the height limiter to the surface of the conveyor belt is such that only a single cigarette butt can pass through in the radial direction, so that the cigarette butt enters the dispersion trough.

[0017] As a further improvement, the width of the dispersion groove is such that only a single cigarette butt can enter in the radial direction, to prevent cigarette butts from stacking in the radial direction. Attached Figure Description

[0025] To address the technical problem of low dispersion efficiency of piled cigarette butts, the basic technical concept of this utility model is: by constructing a cigarette butt channel that allows only a single cigarette butt to pass through radially, the continuous dispersion of piled cigarette butts is achieved while preventing deformation of the cigarette butts, and the cigarette butts are continuously output while maintaining a dispersed state by a conveyor belt, thereby significantly improving the efficiency of cigarette butt dispersion.

[0026] The present invention will be further described in detail below with reference to the embodiments.

[0027] Specific embodiments of the cigarette butt dispersion device provided by this utility model:

[0028] like Figure 1 , Figure 2 and Figure 5As shown, the cigarette butt dispersing device includes a pair of rollers driven by a roller drive motor 5. These two rollers are horizontally spaced apart, and the radial distance between them forms a cigarette butt channel 6 through which only a single cigarette butt 1 can pass. Tangential baffles 2 are provided above the two rollers, and axial baffles 11 are provided at both ends of the rollers. Below the two rollers is a conveyor belt 8 driven by a drive motor 10. The basic structure of the conveyor belt 8 is consistent with existing technology, including an annular belt body, rollers supporting the belt body, and a transmission mechanism, etc., which will not be described in detail here. Below the two rollers and at the beginning of the conveyor belt 8, there is also a ramp 7. The ramp 7 is fixedly connected to the frame of the conveyor belt 8, and the distance from the bottom of the ramp 7 to the surface of the conveyor belt 8 is less than the diameter of a single cigarette butt 1. This prevents the cigarette butt 1 from falling onto the conveyor belt and popping out, and also prevents interference between the ramp 7 and the conveyor belt 8. In addition, a scraper 9 is connected to the conveyor belt 8 behind the ramp 7.

[0029] Before carrying out decentralized operations, cigarette butts 1 can be collected from public smoking areas such as airports and train stations, and after removing impurities from the cigarette butts 1, a batch of cigarette butts 1 can be obtained.

[0030] Specifically, such as Figure 1 As shown, the two rollers are set horizontally spaced apart with a distance of [missing information]. δ Considering that the butt diameter (i.e., the cigarette diameter) of medium-sized cigarettes, slim cigarettes, and regular cigarettes are not the same, and that twice the diameter of the thinnest cigarette is greater than the diameter of the thickest cigarette, the spacing between the two rollers... δ It is configured to be larger than the diameter of the thickest cigarette butt and less than twice the diameter of the thinnest cigarette butt. In other words, this interval applies to the butts of medium-sized cigarettes, slim cigarettes, and regular cigarettes. δ This ensures that only a single cigarette butt 1 can pass through in the horizontal direction and along the radial direction of the rollers, thus dispersing the cigarette butt 1 into individual units. The two rollers can be mounted on a support frame or fixed at a certain height using a hoisting method. Tangential baffles 2 are spaced apart above the two rollers, and the gap between the bottom of the tangential baffles 2 and the surface of the rollers is smaller than the diameter of the thinnest cigarette butt 1, to prevent the cigarette butt 1 from falling tangentially along the rollers. This gap constitutes an escape-proof gap to prevent the cigarette butt 1 from "escaping" tangentially along the rollers. Axial baffles 11 are located at both ends of the two rollers in the axial direction, and the outer edge of the axial baffles 11 protrudes from the outer circumference of the rollers to prevent the cigarette butt 1 from "escaping" axially along the rollers. After being dispersed by the cigarette butt channel 6, the cigarette butt 1 falls onto the ramp 7 below the two rollers and slides down the ramp 7 onto the conveyor belt 8. The distance between the scraper 9 and the surface of the conveyor belt 8 is greater than the diameter of the thickest cigarette butt but less than twice the diameter of the thinnest cigarette butt. During the process of the cigarette butt 1 being transported from the beginning to the end of the conveyor belt 8, the stacked cigarette butt 1 is further dispersed by the scraper 9, and finally the cigarette butt 1 is output as completely flattened cigarette butts.

[0031] Furthermore, regarding the rollers, the two rollers can be connected by a drive mechanism, for example, through a spur gear mechanism at the ends. In this case, only one roller drive motor 5 needs to be configured, which is connected to one of the rollers, forming the driving roller 3. The other roller can rotate with the driving roller 3, forming the driven roller 4. Alternatively, roller drive motors 5 can be configured for each of the two rollers separately. The input cigarette butt 1 can fall onto the two rollers and pass through the gap between the two rollers. The gap between the two rollers ensures that no more than two cigarette butts 1 will stack together and pass through simultaneously in the radial direction of the cigarette butts, thus dispersing the cigarette butts 1 into independent individuals.

[0032] like Figure 1 As shown, the two rollers rotate in opposite directions, and at the interval, both rollers rotate upwards. Alternatively, at the interval, the upward rotation of the two rollers causes the cigarette butt 1 located between the two rollers to tend to move upwards, thus having a kneading and separating effect on the cigarette butt 1, ensuring a dispersion effect.

[0033] Furthermore, regarding the length of the gap between the two rollers in the direction parallel to the roller axis, the axial length of the two rollers is preferably [value missing]. l , l The length of the cigarette butt channel 6 is approximately equal to that of a regular cigarette. Since the cigarette butt channel 6 is formed by two rollers spaced apart, the axial length of the two rollers should be equal to the length of the cigarette butt channel 6. Therefore, the length of the cigarette butt channel 6 should also be... l At this time, the cigarette butt channel 6 allows multiple cigarette butts 1 to pass through simultaneously in the axial direction of the roller, while only one cigarette butt 1 can pass through in the radial direction of the roller, so as to ensure the dispersion effect of the roller assembly on the cigarette butts 1.

[0034] The advantage of using two spaced rollers to construct the cigarette butt channel 6 is that the rotation of the rollers can agitate the cigarette butts 1 located above them, and the width of the cigarette butt channel 6 always matches the diameter of the cigarette butts 1. This achieves continuous separation of the batch input cigarette butts 1, improves the dispersion efficiency of the cigarette butts 1, and prevents the cigarette butts 1 from deforming when passing through the cigarette butt channel 6, which facilitates subsequent cigarette butt image acquisition.

[0035] Furthermore, regarding the tangential baffle 2, since the rotation of the two rollers has a kneading and separating effect on the cigarette butt 1, such as Figure 1As shown, two tangential baffles 2 are installed above the two rollers, and the distance from the bottom of the tangential baffles 2 to the surface of the two rollers is less than the diameter of the thinnest cigarette butt 1, to prevent the cigarette butt 1 from "escaping" tangentially along the surface of the two rollers. The side of the two rollers that is closer together radially is defined as the inner side, and the side that is farther apart is defined as the outer side. Preferably, the intersection point of the bottom extension lines of the two tangential baffles 2 with the two rollers is located at the highest point (arc apex) of the rollers or inside the highest point of the rollers, so that each cigarette butt 1 can smoothly enter the cigarette butt channel 6. This is because when the intersection point of the bottom extension lines of the two baffles 2 with the two rollers is located outside the rollers, that is, when the tangential baffles 2 are located outside the arc apex of the rollers, since the cigarette butt channel 6 between the two rollers is turned upwards, when a batch of cigarette butts 1 enters above the rollers, under the rotation of the roller assembly, the cigarette butts 1 easily accumulate between the arc apex of the two rollers and the two tangential baffles 2.

[0036] Furthermore, regarding the axial surrounding plate 11, when the input speed of the cigarette butt 1 is greater than the separation speed of the roller, the axial surrounding plate 11 should be arranged on both sides of each roller and should not rotate with the roller. The axial surrounding plate 11 on both sides of each roller and the outer peripheral surfaces of the two rollers together form a cigarette butt channel 6 with structures at both ends that prevent the cigarette butt from "escaping." Specifically, as shown... Figure 5 As shown, the two rollers are driven to rotate relative to each other by a rotating shaft. The axial surrounding plate 11 is connected to the rotating shaft of the rollers through a bearing. The axial surrounding plate 11 can be a rectangular plate connected to the end of the roller, and the rectangular plate does not rotate with the roller. The ends of the rectangular plates on the two rollers that are close to each other are attached together, or the rectangular plates on the two rollers are spaced apart, but the distance between them should be less than the diameter of the thinnest cigarette butt 1, so as to prevent the stacked cigarette butts 1 from "escaping" from the axial direction of the roller.

[0037] When the input speed of cigarette butt 1 is equal to the separation speed of the roller, or when the input speed of cigarette butt 1 is less than the separation speed of the roller, such as Figure 2 As shown, flanges are provided at both ends of the roller along its axial direction to serve as axial enclosures 11. These flanges prevent the cigarette butts 1 from "escaping" along the roller's axial direction, thus avoiding a cluster of cigarette butts 1 falling into the next stage of cigarette butt image acquisition and ensuring the dispersion of the cigarette butts 1. Specifically, the flanges and the outer circumferences of the two rollers together form a width of... δ , length is l The cigarette butt channel 6 has a baffle that prevents cigarette butts from escaping axially from the two rollers. The baffle is a circular plate installed at the end of the roller, or it can be a baffle edge integrally formed with the roller. In either case, the radius difference between the baffle and the roller should be greater than the radius of the thickest cigarette butt and less than the diameter of the thinnest cigarette butt, so that the cigarette butt channel 6 can only allow a single cigarette butt 1 to pass through radially.

[0038] The advantage of setting up the tangential baffle 2 and the axial baffle 11 is that when the dispersion speed of the cigarette butt channel 6 is less than the input speed of the cigarette butt 1, the cigarette butt 1 will accumulate above the roller. The tangential baffle 2 and the axial baffle 1 can prevent the batch of cigarette butts 1 from "escaping" along the tangential and axial directions of the two rollers.

[0039] Furthermore, regarding slope 7, as... Figure 1 As shown, after being dispersed by the cigarette butt channel 6, the cigarette butts 1 fall onto the ramp 7 below the two rollers and roll sequentially down the ramp 7 onto the conveyor belt 8. To prevent the cigarette butts 1 from rolling down too fast and accumulating at the beginning of the conveyor belt 8, and to prevent the cigarette butts 1 from rolling down too slowly and accumulating on the ramp 7, the force exerted on the cigarette butts 1 on the ramp 7 is calculated to determine the optimal slope of the ramp 7, thereby controlling the time it takes for the cigarette butts 1 to reach the beginning of the conveyor belt 8 from the cigarette butt channel 6.

[0040] Specifically, such as Figure 4 As shown, the mass of cigarette butt 1 is defined as... m The radius of cigarette butt 1 is defined as r The inclination angle of slope 7 is θ The coefficient of static friction between slope 7 and cigarette butt 1 is μ s According to Newton's second law and the law of rotation, the condition for cigarette butt 1 to roll down slope 7 can be expressed as:

[0041] tan θ ≤3 μ s

[0042] When the slope is too small, and the weight of cigarette butt 1 is insufficient to overcome static friction, cigarette butt 1 will remain on slope 7. At this time:

[0043] tan θ ≤ μ s

[0044] Therefore, the slope of ramp 7 should be set as follows:

[0045] arctan( μ s ) < θ ≤arctan(3) μ s )

[0046] Within the aforementioned slope range, by adjusting the slope of ramp 7, the time required for cigarette butt 1 to reach the beginning of conveyor belt 8 from cigarette butt channel 6 is adjusted, and the conveying speed of conveyor belt 8 is adjusted according to the required time, thereby preventing cigarette butt 1 from accumulating on conveyor belt 8.

[0047] The advantage of setting up ramp 7 is that it receives the cigarette butts 1 dispersed by the cigarette butt channel 6 and transports them to the conveyor belt 8. Compared to the method of letting the dispersed cigarette butts 1 fall directly onto the conveyor belt 8, ramp 7 increases the distance that the cigarette butts 1 are transported from the cigarette butt channel 6 to the conveyor belt 8. While the conveyor belt 8 maintains the same conveying speed, the distance between two cigarette butts 1 transported to the conveyor belt 8 is increased, reducing the risk of cigarette butts 1 piling up on the conveyor belt 8. Furthermore, after the cigarette butts dispersed by the cigarette butt channel 6 are received by ramp 7, the direction of transport changes from vertical downward to diagonally downward, avoiding the situation where the cigarette butts 1 fall directly onto the conveyor belt 8 and are bounced out.

[0048] Furthermore, regarding conveyor belt 8, such as Figure 1 and Figure 3 As shown, cigarette butts 1 dispersed through cigarette butt channel 6 flow onto conveyor belt 8 via ramp 7. Both sides of conveyor belt 8 are fixedly connected to baffles 8-2. Specifically, baffles 8-2 are mounted on the frame and are fitted with a clearance fit to both sides of conveyor belt 8 to prevent them from obstructing the normal rotation of conveyor belt 8 and to prevent cigarette butts 1 from falling off both sides of conveyor belt 8.

[0049] Furthermore, such as Figure 3 As shown, the conveyor belt 8 has multiple dispersing grooves 8-1 arranged at intervals along the conveying direction of the conveyor belt 8. For example, multiple protrusions arranged at intervals can be provided on the conveyor belt 8, and the space between two adjacent protrusions constitutes the dispersing groove 8-1. Specifically, the dispersing groove 8-1 is used to hold the conveyed cigarette butts 1, and the width direction of the dispersing groove 8-1 is parallel to the conveying direction of the conveyor belt 8, thereby regulating the orientation of the cigarette butts 1 on the conveyor belt 8, which facilitates subsequent photography of the cigarette butts 1. The advantage of setting the dispersing groove 8-1 is that the dispersing groove 8-1 not only keeps the cigarette butts 1 in a dispersed state, but the setting direction of the dispersing groove 8-1 also determines the placement angle of the cigarette butts 1 on the conveyor belt 8, so that the cigarette butts 1 can be distributed on the conveyor belt 8 at a specified position and angle, so that they flow into the next process of photographing the cigarette butts 1 in a specified orientation.

[0050] Furthermore, the width of the dispersion groove 8-1 is greater than the diameter of the thickest cigarette butt and less than twice the diameter of the thinnest cigarette butt. In other words, the width of the dispersion groove 8-1 in the radial direction of the cigarette butt 1 is such that only one cigarette butt is allowed to enter, so as to prevent the cigarette butts 1 from stacking in the radial direction and avoid too many cigarette butts 1 from entering the subsequent image acquisition area at the same time.

[0051] Furthermore, the length of the dispersion groove 8-1 is twice the length of a conventional cigarette, allowing multiple axially arranged cigarette butts 1 to enter. In this case, multiple axially arranged cigarette butts 1 can enter the same dispersion groove 8-1 along the length direction, thereby achieving synchronous dispersion of multiple cigarette butts 1 and improving dispersion efficiency.

[0052] Furthermore, a height-limiting component, namely a scraper 9, is installed on the conveyor belt 8. The distance between the scraper 9 and the surface of the conveyor belt 8 is larger than the diameter of the thickest cigarette butt but smaller than twice the diameter of the thinnest cigarette butt butt, ensuring that only a single cigarette butt 1 can pass through radially. Specifically, the scraper 9 is fixed to the frame of the conveyor belt 8 and is located near the tail end of the conveyor belt 8. Here, the distance between the scraper 9 and the conveyor belt 8 refers to the distance between the height-limiting component and the bottom of the dispersion trough 8-1. The advantage of this is that the scraper 9 is a rigid structure, acting as a "safety net." If there are still stacked cigarette butts 1 on the conveyor belt 8, the conveyor belt 8 moves the cigarette butts 1 to the right. When the cigarette butts 1 move to contact the scraper 9, the conveyor belt 8 continues to move the cigarette butts 1, and the stacked cigarette butts 1 are completely dispersed into the dispersion trough 8-1 by the scraper 9, thus ensuring that the cigarette butts 1 are completely flattened and there is no longer any stacking in the radial direction.

[0053] In addition, the conveyor belt 8 is connected to a vibration mechanism, which drives the belt surface of the conveyor belt 8 to vibrate, causing the cigarette butts 1 on the conveyor belt 8 to bounce and assist the cigarette butts 1 in entering the dispersion trough 8-1. Specifically, the vibration mechanism can adopt a vibrator with a reciprocating motion structure as used in existing technology, and the power source can be a motor, hydraulic cylinder, air cylinder, hydraulic motor, etc., making the conveyor belt 8 a vibrating conveyor. The benefit of increasing vibration is that the vibration transmission of the conveyor belt 8 can keep the cigarette butts 1 vibrating while being transmitted, thus making it easier for the cigarette butts 1 to automatically enter the dispersion trough 8-1 during the transmission process, which can improve the dispersion efficiency of the cigarette butts 1 and reduce the risk of the cigarette butts 1 accumulating in front of the height limiter.

[0054] In other embodiments, the conveyor belt 8 can also be inclined, with its tail end facing upwards. The ramp 7 at the head end of the conveyor belt 8 can act as a baffle to prevent cigarette butts 1 from falling. Specifically, the inclined conveyor belt 8 with its tail end facing upwards can utilize the weight of the cigarette butts 1 and the height limiting component to disperse the stacked cigarette butts 1. The baffle is used to stop the cigarette butts 1 being conveyed onto the conveyor belt 8, preventing them from falling from the head end of the conveyor belt 8.

[0055] In other embodiments, the height limiting component may also use a soft brush. The soft brush itself has flexible bristles that will not damage the structure of the cigarette butt 1 itself, for example, it will not cause the cigarette butt 1 to be flattened, and it can also be used for cigarette butts 1 of different diameters. Specifically, the distance between the soft brush and the conveyor belt 8 should be set to be larger than the diameter of the thickest cigarette butt and smaller than twice the diameter of the thinnest cigarette butt, so that the soft brush can separate two overlapping cigarette butts 1.

[0056] In other embodiments, it is possible that the height limiter is mounted on the frame of the conveyor belt to limit its movement. In this case, the height limiter can move up and down in a direction perpendicular to the surface of the conveyor belt 8 to adjust the distance from the surface of the conveyor belt 8, thereby dispersing cigarette butts 1 stacked to different degrees and preventing cigarette butts 1 from accumulating in front of the height limiter.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
