Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing technology, specifically to a cigarette tube and tobacco separation device and method. Background Technology

[0002] In the process of developing new cigarette products, it is usually necessary to prepare parallel samples with multiple formulations for evaluation. When preparing small batches of samples, the following methods are mainly used: (1) Prepare the sample to be evaluated by the rolling equipment. However, since the sample produced by the rolling equipment in one run far exceeds the required sample quantity, a lot of waste is caused. This method is generally not recommended when preparing samples for evaluation. (2) Remove the tobacco from the cigarette by tweezers or air gun and then manually fill it with tobacco to obtain the evaluation sample. This method is cumbersome and inefficient. At the same time, it is easy to cause deformation and damage to the end of the empty cigarette tube, affecting the parameters such as the resistance of the sample for evaluation. This results in a large gap between the quality of the cigarette produced by the rolling equipment and the evaluation results.

[0003] Meanwhile, during the production of finished cigarettes, a large number of defective cigarettes are generated due to start-up and shutdown, errors, and malfunctions of the rolling and packaging equipment. To control costs, these cigarettes need to be recycled, and the tobacco and cigarette tubes need to be separated for recycling. Currently, the common separation method is to separate the tobacco and cigarette paper by cutting and crushing. However, this method results in a large amount of damage and fragmentation of the tobacco, and the empty cigarette tubes are damaged and cannot be recycled.

[0004] The prior art disclosed in patent publication number CN113974208B is a tobacco removal device and its control method. It proposes to remove tobacco from experimental cigarettes by using multiple sets of cigarette rollers and cigarette contouring clamps. This method can effectively avoid cigarette deformation. However, this method only considers the protection of empty cigarette tubes during the separation of cigarette tubes and tobacco, but does not address the protection of empty cigarette tubes when cigarette tubes are piled up during the collection process. It does not have the function of removing samples of tobacco that have not been successfully separated. At the same time, it does not consider that the end of the cigarette butt may deform under a large airflow.

[0005] The prior art disclosed in patent publication number CN116268549A is a fully automatic cigarette blower. It proposes to adapt to the separation of cigarette tubes and tobacco shreds of various diameters by setting a cigarette diameter detector below the hopper. However, this method also does not involve the protection of empty cigarette tubes when cigarette tubes are piled up during the collection process, does not have the function of rejecting samples of tobacco shreds that have not been successfully separated, and does not consider that the end of the cigarette butt may be deformed under a large airflow.

[0006] The prior art disclosed in patent publication number CN109000957 B is a tobacco removal device for finished cigarettes. It proposes to remove tobacco from the cigarette tube by using a tobacco removal needle, which can effectively avoid deformation of the cigarette butt end of the empty cigarette tube and minimize the impact on the evaluation results when preparing small batches of samples. However, this method does not address the protection of the empty cigarette tube when the cigarette tubes are piled up during the collection process, and it does not have the function of removing samples from which tobacco was not successfully separated.

[0007] Current inventions and devices all have the following problems: current technologies only consider the protection of empty tobacco tubes during the separation of tobacco tubes and tobacco, but do not address the protection of empty tobacco tubes when tobacco tubes are piled up during the collection process; they do not have the function of removing samples of tobacco that have not been successfully separated; and they do not consider the problem that the end of the cigarette butt may deform under strong airflow. Summary of the Invention

[0008] The technical problem to be solved by the present invention is: how to provide an integrated device for the automatic separation of cigarette tubes and tobacco, and the collection and protection of empty cigarette tubes after separation.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A cigarette tube and tobacco shred separation device includes a main structure, and also includes a tobacco shred collection mechanism, a sample separation judgment unit, a sample injection mechanism, an operation control mechanism, and an empty cigarette tube collection unit installed on the main structure. The control mechanism controls the sample to be injected into the sample injection mechanism. The sample falls from the sample injection mechanism into the sample separation judgment unit for tobacco separation. The weighing component in the sample separation judgment unit monitors the weight of the tobacco before and after separation. After separation, the tobacco in the sample is blown into the tobacco collection mechanism through the tobacco collection tube, and the remaining empty tobacco tube falls into the empty tobacco tube collection unit.

[0010] This application integrates a tobacco collection mechanism, a sample separation and judgment unit, a sample feeding mechanism, an operation control mechanism, and an empty tobacco tube collection unit into the main structure, enabling fully automatic sample feeding, unloading, tobacco separation, and tobacco tube collection. Furthermore, a weighing component is installed during the tobacco separation process to determine the mass change of the sample before and after tobacco separation, to determine whether the tobacco has been completely discharged, and to reject samples that have not successfully expelled tobacco, thereby improving the accuracy of tobacco tube sorting.

[0011] As a further aspect of the present invention: the sample separation and judgment unit includes a gripper cylinder and an upper guide block and a lower guide block located on its upper and lower sides. A tobacco blowing assembly is also provided on one side of the gripper cylinder. The sample from the sample feeding mechanism falls into the upper guide block, and then the sample is gripped by the gripper cylinder and rotated 90 degrees by the rotation drive component. Then, the tobacco is separated from the sample by the tobacco blowing assembly. After being gripped by the gripper cylinder, the empty tobacco tube rotates 90 degrees and enters the empty tobacco tube collection unit through the lower guide block.

[0012] As a further aspect of the present invention: the rotary drive component includes a displacement adapter plate connected to one side of the upper guide block and a displacement cylinder connected to one side of the displacement adapter plate. The side of the displacement cylinder away from the upper guide block is connected to a rotary cylinder through the rotary adapter plate. The gripper cylinder is installed below the displacement adapter plate. The displacement cylinder can drive the clamping structure at the front end of the gripper cylinder and the upper guide block to move simultaneously. The rotary cylinder can drive the clamping structure and the upper guide block to rotate simultaneously.

[0013] As a further aspect of the present invention: the weighing assembly includes a weighing unit rod disposed below the gripper cylinder and a weighing unit disposed at the end of the weighing unit rod and connected thereto. The weighing unit rod is located on the top side of the lower guide block, and the displacement cylinder can drive the clamping structure and the upper guide block to move directly above the weighing unit rod.

[0014] As a further aspect of the present invention: the two sides of the lower guide block are fixed to the main structure by positioning seats, and a photoelectric switch for determining the position of the sample is provided on the top of the two positioning seats.

[0015] As a further aspect of the present invention: the blowing assembly includes a sizing cover mounted on one side of the gripper cylinder, and an air blowing nozzle is provided on the side of the sizing cover near the gripper cylinder. The bottom of the air blowing nozzle is connected to an air blowing nozzle displacement cylinder located at the bottom of the inner side of the sizing cover via an air blowing nozzle mounting plate. An electromagnetic proportional valve for adjusting the blowing pressure of the air blowing nozzle is also provided on the sizing cover.

[0016] As a further aspect of the present invention: the upper guide block and the clamping structure at the front end of the gripper cylinder are always coaxial. After the sample tobacco is separated, the upper guide block, the gripper cylinder and the lower guide block are coaxial.

[0017] As a further aspect of the present invention: the empty smoke tube collection unit includes a moving base plate, wherein the bottom of the moving base plate is mounted to the main structure via a longitudinal guide rail, and the top of the moving base plate is provided with a collection box seat, wherein the bottom of the collection box seat is mounted to the moving base plate via a transverse guide rail, and the collection box seat includes a collection box A and a collection box B. A photoelectric switch and a proximity switch are installed on the moving base plate to monitor the position of collection box A and collection box B.

[0018] As a further aspect of the present invention: the collection box A is located on one side of the collection box B, and the two are at the same height. The interior of the collection box A is provided with several cylindrical deep holes for placing empty cigarette tubes with completely removed tobacco. The collection box B is an integral deep groove for placing cigarette tubes with incompletely removed tobacco.

[0019] The present invention also discloses a separation method for cigarette tubes and tobacco shreds separation device, comprising the following steps: S1. The injection mechanism starts to inject samples after being set and controlled by the operation control mechanism. S2. Then the sample falls from the injection mechanism into the sample separation judgment unit. First, the mass of the sample before separation is monitored by the weighing component. After weighing, the tobacco is separated. After separation, the mass of the sample is detected by the weighing component again. By judging the change in mass of the sample before and after separation, it is determined whether the tobacco is completely discharged. S3. The separated empty cigarette tube falls into the empty cigarette tube collection unit, while the tobacco produced during the separation process is blown into the tobacco collection mechanism through the tobacco collection tube.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. This application integrates the tobacco shred collection mechanism, sample separation and judgment unit, sample feeding mechanism, operation control mechanism and empty cigarette tube collection unit into the main structure, which can realize the fully automatic feeding, unloading, tobacco shred separation and cigarette tube collection of cigarette samples in one integrated manner. In addition, a weighing component is set up during the tobacco shred separation process to determine the mass change of the sample before and after tobacco shred separation, and to determine whether the tobacco shreds are completely discharged, thereby improving the accuracy of the next step of cigarette tube sorting. 2. This application, by setting up a weighing unit and a weighing unit rod, can measure the weight of the tobacco before and after separation of the tobacco from the pipe, thereby determining the degree of separation between the tobacco and the pipe. Then, in conjunction with the two collection boxes in the empty pipe collection unit at the bottom, the empty pipes that have been completely de-extracted from the tobacco and the pipes that have not been completely de-extracted from the tobacco are stored separately, thereby avoiding deformation caused by subsequent stacking of the pipes. The above weight sorting can accurately remove pipe samples that have not successfully expelled the tobacco. 3. By combining a gripper cylinder, a displacement cylinder, and a rotary cylinder, this application enables the separation and weighing of tobacco shreds in a single process, saving space while improving the efficiency of tobacco shred separation. Furthermore, the gripping structure at the front end of the gripper cylinder is easy to replace and can be adapted to different types of samples. 4. This application provides an air blowing nozzle on one side of the gripper cylinder. The height of the air blowing nozzle can be adjusted as needed. With the cooperation of the displacement cylinder, the rotation cylinder and the gripper cylinder, the cigarette sample can be adjusted to be on the same horizontal line as the air blowing nozzle by rotation and movement, in preparation for the separation of tobacco from the air blowing nozzle. The air blowing nozzle can also self-adjust the blowing pressure, the structure of the air blowing nozzle and the opening size to avoid deformation of the end face of the cigarette tube filter. 5. This application can realize the collection of tobacco shreds, the collection of tobacco tubes, and the calculation of the actual tobacco shred filling value in the tobacco tubes. The three functions are integrated into the main structure. The structure is interlocked, highly coordinated, and automatically controlled, bringing convenience to staff and the industry.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figure 1 and Figure 2 A cigarette tube and tobacco shred separation device includes a rectangular main structure 1, a sample feeding mechanism 6 installed above the main structure 1, a sample separation judgment unit 5 disposed on the main structure 1 and below the sample feeding mechanism 6, a tobacco shred collection tube 3 connected to a tobacco shred collection mechanism 2 located on one side of the main structure 1 via a tobacco shred collection tube 3, and the tobacco shred collection tube 3 is installed on the main structure 1 via a tobacco shred collection tube adjustment mechanism 4; an empty cigarette tube collection unit 8 disposed on the main structure 1 and below the sample separation judgment unit 5; and an operation control mechanism 7 disposed on one side of the main structure 1.

[0024] The specific route for cigarette tube feeding, tobacco separation, and cigarette tube collection is as follows: The sample (i.e., the cigarette) enters the sampling mechanism 6, and then falls from the sampling mechanism 6 into the sample separation and judgment unit 5 located directly below. Subsequently, the sample is weighed and the tobacco is separated through the sample separation and judgment unit 5. The tobacco generated during the separation process enters the tobacco collection mechanism 2 through the tobacco collection tube 3 for storage, while the remaining cigarette tube enters the empty cigarette tube collection unit 8 located directly below for storage. The entire operation is intelligently controlled by the operation control mechanism 7 to achieve automation without the need for manual assistance.

[0025] Reference Figure 1 and Figure 2 The main structure 1 is a three-dimensional frame structure with an upper top plate and a lower bottom plate. The upper top plate and the lower bottom plate are connected by columns at the four corners. A middle partition is also provided between the upper top plate and the lower bottom plate. The sample injection mechanism 6 of this application is installed on the upper top plate, while the sample separation and judgment unit 5 is installed on the middle partition, and the empty smoke tube collection unit 8 is installed on the lower bottom plate.

[0026] Reference Figure 1 and Figure 2 The tobacco collection mechanism 2 is installed on the outside of the main structure 1 and is connected to the outlet end of the tobacco collection pipe 3. The tobacco collection pipe 3 can discharge the collected tobacco into the tobacco collection mechanism 2 for storage. The tobacco collection mechanism 2 can be installed on the main structure 1 in a detachable manner, which can be easily disassembled at any time to remove the tobacco inside.

[0027] Reference Figure 1 and Figure 2 One end of the tobacco collection tube 3 is connected to the tobacco discharge position of the sample separation and judgment unit 5, and the other end is connected to the tobacco collection mechanism 2. The middle of the tobacco collection tube 3 is mounted on the main structure 1 through the tobacco collection tube adjustment mechanism 4. The tobacco collection tube adjustment mechanism 4 is an arc-shaped buckle and can be mounted on the main structure 1 by bolts, etc. The assembly state of the tobacco collection tube is as follows: Figure 2 As shown; during the blowing process, the gripper cylinder 53 holds the sample and rotates it 90 degrees by the rotary cylinder 55, and the blowing nozzle 59 is coaxial with the upper guide block 58, the sample 515 and the tobacco collection tube 3.

[0028] Reference Figure 3 and Figure 4 The sample separation and judgment unit 5 includes a gripper cylinder 53 and an upper guide block 58 and a lower guide block 516 located on its upper and lower sides. A displacement transition plate 57 is provided on one side of the upper guide block 58, and a displacement cylinder 54 is connected to the other side of the displacement transition plate 57. The displacement cylinder 54 is installed on the main structure 1. The side of the displacement cylinder 54 away from the upper guide block 58 is connected to a rotary cylinder 55 through a rotary transition plate 56. The gripper cylinder 53 is installed below the displacement transition plate 57. The displacement cylinder 54 can drive the clamping structure 518 and the upper guide block 58 at the front end of the gripper cylinder 53 to move simultaneously. The rotary cylinder 55 can drive the clamping structure 518 and the upper guide block 58 to rotate simultaneously.

[0029] Furthermore, a weighing unit rod 519 is provided below the gripper cylinder 53. The end of the weighing unit rod 519 is provided with a weighing unit 52 connected to it. The weighing unit rod 519 is located on the top side of the lower guide block 516. The displacement cylinder 54 can drive the clamping structure 518 and the upper guide block 58 to move directly above the weighing unit rod 519. The two sides of the lower guide block 516 are fixed to the main structure 1 by positioning seats 517. A photoelectric switch 513 for judging the sample position is also provided on the top of the two positioning seats 517.

[0030] Furthermore, a leveling cover 511 is provided on one side of the gripper cylinder 53. An air nozzle 59 is provided on the side of the leveling cover 511 near the gripper cylinder 53. The bottom of the air nozzle 59 is connected to the air nozzle displacement cylinder 514 located at the bottom of the inner side of the leveling cover 511 through the air nozzle mounting plate 510. An electromagnetic proportional valve 512 for adjusting the blowing pressure of the air nozzle 59 is also provided on the leveling cover 511. The upper guide block 58 and the clamping structure 518 at the front end of the gripper cylinder 53 are always coaxial. After the sample tobacco is separated, the upper guide block 58, the gripper cylinder 53 and the lower guide block 516 are coaxial.

[0031] When the sample from the injection mechanism 6 falls into the upper guide block 58, the sample falls onto the weighing unit rod 519 and is weighed before separation by the weighing unit rod 519. After weighing, the clamping structure 518 is clamped by the gripper cylinder 53 and rotated 90 degrees by the rotary drive. Then, the blowing pressure is adjusted by the electromagnetic proportional valve 12 and the blowing nozzle 9 blows air, thereby separating the tobacco and the tobacco tube. The rotary cylinder 55 clamps the separated empty tobacco tube and rotates 90 degrees before falling back onto the weighing unit rod 519 for re-weighing. Subsequently, when the displacement cylinder 54 moves forward and the gripper cylinder 53 opens, the upper guide block 58, the lower guide block 516 and the sample 515 are concentric. The sample 515 falls freely from the lower guide block 516 and is discharged into the empty tobacco tube collection unit 8.

[0032] It should be noted that the clamping structure 518 and the upper guide block 58 can be quickly plugged in and replaced; the electromagnetic proportional valve 512 can precisely control the air pressure, which can effectively prevent the sample cigarette butt end face from deforming due to excessive blowing pressure.

[0033] The specific workflow of sample separation and judgment unit 5: Sample 515 falls through the upper guide block 58. At this time, the rotary cylinder 55 and the displacement cylinder 54 return to their positions, and the gripper cylinder 53 controls the two clamping mechanisms 518 at the front end to be in the open state. At this time, sample 515 falls freely above the weighing unit rod 519 under gravity. The weighing unit 52 completes the mass recording. After the weighing is completed, the gripper cylinder 53 drives the clamping mechanism 518 to clamp sample 515. Then, the rotary cylinder 55 controls the gripper cylinder 53, the clamping mechanism 518, the sample 515 and the upper guide block 58 to rotate 90°, and the position is finely adjusted by the displacement cylinder 54. Then, the air nozzle displacement cylinder 514 moves forward with the air nozzle mounting plate 510 and the air nozzle 59, so that the air nozzle 59 contacts and seals with the clamping structure 518. Then, the electromagnetic proportional valve controls the gas pressure to separate the tobacco and the tobacco tube. Afterwards, the rotary cylinder 55 and the air nozzle displacement cylinder 514 return to their positions, and the gripper cylinder 53 controls the two clamping mechanisms 518 at the front end to open. The tobacco tube after tobacco separation falls back above the weighing unit rod 519, and the weighing unit 52 records the mass of the sample 515 again. Then, the displacement cylinder 54 moves forward, causing the sample 515 to slide from the weighing unit rod 519 into the lower guide block 516. At this time, the through-beam switch 513 judges the position of the sample 515, and then the sample 515 is discharged by the lower guide block 516. After completing the above actions, the displacement cylinder 54 resets and waits for the next group to proceed.

[0034] It should be noted that the mouthpiece 59 consists of two cavities, one large and one small, which are interconnected. The opening size of the small cavity needs to be greater than 4mm, and the opening size of the large cavity needs to be greater than the diameter of the thickest cigarette. The depth needs to ensure that the end of the cigarette butt cannot touch the mouthpiece 59 structure. A flexible clamping finger 5181 is provided on the side of the clamping structure 518 that contacts the cigarette tube. When the flexible clamping finger 5181 is closed, it forms an elliptical shape. To ensure a complete seal, the circumference of the ellipse is equal to the circumference of the cigarette. The length of the flexible clamping finger 5181 needs to be less than the length of the filter. A deep groove is carved on the side of the flexible clamping finger 5181 that contacts the mouthpiece 59. After contacting the mouthpiece 59, the protruding part of the mouthpiece 59 can penetrate into the flexible clamping finger 5181 to achieve a sealing effect.

[0035] Reference Figure 1 and Figure 2 The sample feeding mechanism 6 is used to store the sample to be blown and can make the sample fall vertically into the sample separation judgment unit 5 by gravity.

[0036] Reference Figure 1 and Figure 2 The operation control mechanism 7 controls the entire process of sample feeding, tobacco separation, feeding and empty pipe collection. The staff only needs to control the operation control mechanism 7.

[0037] Reference Figure 7 The air pipe collection unit 8 includes a moving base plate 813, wherein the bottom of the moving base plate 813 is mounted on a support block 812 via a longitudinal guide rail 811, and then mounted on the main structure 1 via the support block 812; a longitudinal screw 81 is also provided below the moving base plate 813, the output end of the longitudinal screw 81 is connected to the moving base plate 813, and the longitudinal screw 81 can drive the moving base plate 813 to move longitudinally along the longitudinal guide rail 811.

[0038] Reference Figure 7The top of the moving base plate 813 is provided with a collection box seat 86, the bottom of which is mounted on the moving base plate 813 via a transverse guide rail 89. One side of the collection box seat 86 is connected to a transverse lead screw 814 located above the moving base plate 813 via an adapter plate 85, because the transverse lead screw 814 can drive the collection box seat 86 to move laterally along the transverse guide rail 89. A baffle 84 is also installed on one side of the adapter plate 85, and a photoelectric switch 83 is provided on the moving base plate 813 on the transverse track corresponding to the baffle 84. The photoelectric switch 83 is located on the side of the transverse lead screw 814 and is mounted on the moving base plate 813. The baffle 84 is located between the photoelectric switches 83, so the position of the collection box can be determined by the cooperation of the photoelectric switch 83 and the baffle 84. A proximity switch 810 for monitoring the position of the collection box is also installed on the moving base plate 813.

[0039] Reference Figure 7 The collection box base 86 includes a collection box A87 and a collection box B88. The collection box A87 is located on one side of the collection box B88, and the two are at the same height. The interior of the collection box A87 has several cylindrical deep holes. The depth of the cylindrical holes is less than the length of the cigarette, and the diameter is greater than the diameter of the cigarette, which can ensure that the cigarette is perpendicular to the bottom inside. It is used to place empty cigarette tubes with completely removed tobacco. The collection box B88 is a whole deep groove, and cigarette tubes with incompletely removed tobacco can be placed freely inside.

[0040] The working principle of the empty smoke collection unit 8 is as follows: After the tobacco shreds are separated, the sample falls from the lower guide block 516 in the sample sorting unit 5. The operation control mechanism 7 compares the mass change of the sample before and after to determine whether the tobacco shreds have been completely discharged. If the two masses are different, the sample collection box A87 is aligned with the lower guide block 516 by the longitudinal screw 81 and the transverse screw 814, so that the sample can fall into the hole and avoid deformation caused by the stacking of empty tobacco tubes. If the two masses are the same, the sample collection box B88 is stopped below the lower guide block 516 by the longitudinal screw 81 and the transverse screw 814, and the sample falls into the collection box B88, thereby realizing sample judgment and separation.

[0041] This application enables the collection of tobacco shreds: The above function is achieved through the following operation: Selecting this function on the operation control mechanism 7 causes the empty cigarette tube collection unit 5 to move and align the collection box B88 with the lower guide block 516. Then, the sample injection mechanism 6 starts to inject the sample. The sample falls vertically above the weighing balance bar 519 under the action of gravity. At this time, the weighing balance 519 does not record the mass. The gripper cylinder 53 clamps the sample 515 and rotates it 90° by the rotary cylinder 55. At this time, the control air nozzle 59 is aligned with the clamping structure 518 and sealed. The electromagnetic proportional valve 512 automatically adjusts the blowing pressure to blow out the tobacco. The blown tobacco falls into the tobacco collection mechanism 2 through the tobacco collection tube 3. After completion, the rotary cylinder 55 resets, the gripper cylinder 53 opens, and the displacement cylinder 54 moves to push the sample into the lower guide block and fall into the collection box B88. This process is repeated until all samples are separated.

[0042] This application enables the collection of flue gas: The above function is achieved through the following operation: Selecting this function on the operation control mechanism causes the empty tobacco tube collection unit to move, aligning the hole in the collection box A87 with the lower guide block 516. Then, the sample injection mechanism 6 begins injection. The sample, under the influence of gravity, falls vertically above the weighing balance bar 519, at which point the weighing balance 519 records the mass. Next, the gripper cylinder 53 clamps the sample, which is then rotated 90° by the rotary cylinder 55. At this time, the blowing nozzle 59 is aligned with and sealed against the clamping structure 518. The electromagnetic proportional valve 512 automatically adjusts the blowing pressure to blow out the tobacco. The blown tobacco falls through the tobacco collection tube into the tobacco collection mechanism. After completion, the rotary cylinder 55 resets. The gripper cylinder 53 opens, and the sample falls again above the weighing balance bar 519. The weighing operation control mechanism of the weighing unit 52 compares the mass before and after the weighing. If the two masses are different, the sample collection box A87, driven by the longitudinal screw 81 and the transverse screw 814, aligns its empty position with the lower guide block 516, allowing the sample to fall into the hole and thus avoiding deformation caused by stacking empty pipes. If the two masses are the same, the sample collection box B88, driven by the longitudinal screw 81 and the transverse screw 814, stops below the lower guide block 516, and the sample falls into the collection box B88, thus achieving sample judgment and separation. Afterward, the empty pipe collection unit drives the next hole of the collection box A87 to align with the lower guide block 516, and the sample injection unit injects the sample. This process is repeated until all samples are collected.

[0043] This application enables the calculation of cigarette filling value: The above function is achieved through the following operation: Selecting this function on the operation control mechanism 7 causes the empty tobacco tube collection unit 5 to move, aligning the hole in the collection box A87 with the lower guide block 516. Then, the sample injection mechanism 6 begins injection. The sample falls vertically above the weighing balance bar 519 under gravity. At this time, the weighing balance 519 records the mass and uploads it to the operation control mechanism 7. Next, the gripper cylinder 53 clamps the sample, which is then rotated 90° by the rotary cylinder 55. At this time, the blowing nozzle 59 is aligned with and sealed against the clamping structure 518. The electromagnetic proportional valve 512 automatically adjusts the blowing pressure to blow out the tobacco. The blown tobacco falls through the tobacco collection tube 3 into the tobacco collection mechanism 2. After completion, the rotary cylinder 55 resets, the gripper cylinder 53 opens, and the sample falls again above the weighing balance bar 519. It is weighed by the weighing balance 52, and the operation control machine 7 saves the mass of the sample after blowing and calculates the required tobacco filling value. The displacement cylinder 4 pushes the sample through the lower guide block 516 and falls into the designated hole of the collection box A87. At the same time, the result recorded in the operation control mechanism is consistent with the hole where the sample is located. If the two masses are consistent, the sample collection box B88 is stopped below the lower guide block 516 by the longitudinal screw 81 and the transverse screw 814, and the sample falls into the collection box B88. This process is repeated until all samples are collected.
