Description

Technical Field

[0001] This utility model relates to the technical field of cigarette testing equipment, and in particular to an automatic separation device for tobacco and tobacco tubes. Background Technology

[0002] An empty cigarette tube is a tube containing only the filter rod, tipping paper, and rolling paper, resembling a cigarette after the tobacco has been removed. Empty cigarette tubes are essential experimental materials in cigarette research and development and process evaluation, and are frequently used in these processes. Their main purpose is to roll experimental tobacco into the empty tube using a hand-rolling machine to form sample cigarettes, facilitating sensory quality evaluation and chemical composition analysis. The production of empty cigarette tubes requires separating the tobacco from the tube while ensuring the integrity of the filter and the tube itself.

[0003] There are two conventional methods for making empty cigarette tubes. One is entirely manual, where cigarette paper, tipping paper, and filter rods are manually cut, shaped using a mold, and then glued together with adhesive tape and nozzle glue to form the empty cigarette tube. This method is inefficient, produces cigarette tubes with inconsistent quality, and is prone to contamination and damage. The other method involves removing the tobacco from existing cigarettes and filling them with experimental tobacco. The latter often uses an air gun connected to an air pump, with the air gun's outlet being tubular. The filter end of a cigarette with a filter is inserted into the air gun's outlet, and when the air gun is turned on, the compressed gas blows out the tobacco from the cigarette with the filter. This method is more time-saving and labor-saving than the first method, but it is still slower, has a low pass rate for empty cigarette tubes, and results in significant waste, failing to meet the requirements for rapid experiments. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in related technologies. To this end, this invention proposes an automatic tobacco-to-chimney separation device, designed to achieve automatic separation of tobacco from the chimney.

[0005] The automatic tobacco and tobacco pipe separation device according to an embodiment of the present utility model includes:

[0006] A frame, on which a smoke chamber and a placement plate are provided, wherein multiple cigarettes with filters are arranged in the smoke chamber, and the placement plate is located at the outlet of the smoke chamber and has an elongated hole.

[0007] A first conveying mechanism is adapted to clamp the filter cigarette located on the placement plate and drive the filter cigarette to move.

[0008] The blowing assembly includes a sleeve connected to the frame. The sleeve is located on one side of the placement plate and has an open end and a closed end. The closed end of the sleeve has a communication port for connecting to an external high-pressure air source. The filter end of the filter cigarette is adapted to be inserted into the sleeve under the drive of the conveying mechanism.

[0009] According to the embodiment of this utility model, the automatic tobacco-to-cigarette separation device, through the design of a tobacco chamber, a placement plate, and a conveying mechanism, allows the filter-bearing cigarettes in the tobacco chamber to fall smoothly onto the placement plate. The conveying mechanism then horizontally transports the filter-bearing cigarettes a certain distance, enabling the filter tip of the cigarette to be smoothly inserted into the sleeve. By designing a sleeve that can connect to an external high-pressure gas source, the filter-bearing cigarette can be inserted into the sleeve. The external high-pressure gas source fills the sleeve with high-pressure gas, which passes through the filter tip of the cigarette and blows the tobacco out of the cigarette, thus achieving the separation of the cigarette and tobacco in the filter-bearing cigarette. This separation device is simple and reliable; the tobacco in the filter-bearing cigarette can be completely blown out; and the sleeve fixes the cigarette with the filter, preventing deformation, resulting in a high yield of qualified empty cigarettes.

[0010] According to one embodiment of the present invention, the conveying mechanism includes a lower mounting frame, an upper mounting frame, abutting wheels, and a drive motor. The upper mounting frame is connected to the placement plate. Multiple abutting wheels are horizontally rotatably supported on both the lower and upper mounting frames. The multiple abutting wheels on the lower mounting frame and the multiple abutting wheels on the upper mounting frame are arranged sequentially along the length of the elongated hole. The abutting wheels are adapted to pass through the elongated hole. The multiple abutting wheels on the lower mounting frame and the multiple abutting wheels on the upper mounting frame together clamp a filter cigarette located on the placement plate. The drive motor is connected to the upper mounting frame and is drively connected to the abutting wheels on the upper mounting frame.

[0011] According to one embodiment of the present invention, each of the abutting wheels has an annular limiting groove coaxially provided on its outer side wall. The groove width of the annular limiting groove is smaller than the cross-sectional outer diameter of the cigarette with filter tip. The center line of a cigarette with filter tip on the placement plate is centrally arranged between the two side walls of the annular limiting groove.

[0012] According to one embodiment of the present invention, the conveying mechanism further includes a telescopic cylinder, which is connected to the frame, and the lower mounting frame is connected to the vertical telescopic end of the telescopic cylinder.

[0013] According to one embodiment of the present invention, the output shaft of the drive motor is coaxially fixed with one of the abutment wheels located on the upper mounting bracket.

[0014] According to one embodiment of the present invention, a baffle is further included. The baffle is arranged vertically, with its upper end connected to the upper mounting bracket and its lower end connected to the placement plate. The baffle is adapted to stop the filter cigarettes located on the placement plate.

[0015] According to one embodiment of the present invention, the blowing assembly further includes an elastic tube, a telescopic cylinder II, and a stop block. The elastic tube is coaxially arranged inside the sleeve, and both ends of the elastic tube are sealed and fixed to the inner sidewall of the sleeve. The filter end of the cigarette with filter tip located on the placement plate can be tightly inserted into the elastic tube. The sleeve is horizontally arranged, the telescopic cylinder II is fixed on the frame, and the stop block is fixed to the vertical telescopic end of the telescopic cylinder II. The stop block is adapted to press against the sidewall of the elastic tube.

[0016] According to one embodiment of the present invention, a clearance hole is provided on the outer wall of the sleeve, the clearance hole corresponds to the position of the elastic tube, and the abutment block is adapted to pass through the clearance hole and abut against the side wall of the elastic tube.

[0017] According to one embodiment of the present invention, the automatic tobacco and tobacco tube separation device further includes a second conveying mechanism, which includes guide rollers, a conveyor belt, and a second drive motor. Two guide rollers are horizontally rotatably supported on the frame. The axis of the two guide rollers is the same as the length direction of the elongated hole. The conveyor belt, which is closed at both ends, is fitted onto the two guide rollers. The conveyor belt is provided with a plurality of elongated through holes, which are arranged sequentially along the length direction of the conveyor belt. The lower mounting frame and the plurality of abutting wheels located on the lower mounting frame are adapted to pass through the through holes. The conveyor belt is adapted to receive the filter cigarettes. The second drive motor is fixed to the frame, and the output shaft of the second drive motor is coaxially fixed to one of the guide rollers.

[0018] According to one embodiment of the present invention, the conveyor belt is provided with a plurality of slots, the plurality of slots are arranged sequentially along the length direction of the conveyor belt, and each slot has a through hole arranged on the bottom wall of the slot. The length direction of the slot is the same as the length direction of the through hole, and each slot is suitable for placing a cigarette with a filter.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0033] This utility model discloses an automatic tobacco and cigarette holder separation device. The device comprises a tobacco chamber 2, a placement plate 3, and a conveying mechanism. The conveying mechanism smoothly transfers the filter cigarettes 21 from the tobacco chamber 2 to the placement plate 3. Alternatively, the conveying mechanism can be omitted, allowing the filter cigarettes 21 in the tobacco chamber 2 to roll onto the placement plate 3 under gravity. The filter cigarettes 21 can then be placed into the tobacco chamber 2 one by one manually or via a conveyor belt for sequential processing. The conveying mechanism effectively improves automation, reduces manual operation, and allows multiple filter cigarettes 21 to be placed into the tobacco chamber 2 at once, then sequentially conveyed via the conveying mechanism.

[0034] Multiple abutting wheels 12 located on the lower mounting frame 10 and multiple abutting wheels 12 located on the upper mounting frame 11 can jointly clamp a filter cigarette 21 located on the placement plate 3; while the filter cigarette 21 is being clamped, the drive motor 13 drives the abutting wheels 12 to rotate, thereby horizontally conveying the clamped filter cigarette 21 a certain distance, so that the filter end of the filter cigarette 21 can be smoothly inserted into the sleeve 14.

[0035] By designing a sleeve 14 that can be connected to an external high-pressure gas source, the aforementioned filter cigarette 21 can be inserted into the sleeve 14. The external high-pressure gas source fills the sleeve 14 with high-pressure gas, which can pass through the filter of the filter cigarette 21 and blow out the tobacco in the cigarette tube, thereby achieving the separation of the cigarette tube and the tobacco in the filter cigarette 21. The above separation device is simple and reliable, and the tobacco in the filter cigarette 21 can be completely blown out.

[0036] By relying on the rotation of the guide roller 5 and the fact that the material groove 50 on the guide roller 5 is aligned with the positions of the first strip hole 40 and the second strip hole 41 respectively, the filter cigarette 21 in the cigarette chamber 2 can be smoothly moved onto the placement plate 3.

[0037] The abutting wheel 12 is provided with an annular limiting groove 120. The abutting wheel 12 located on the lower mounting frame 10 and the abutting wheel 12 located on the upper mounting frame 11 can reliably clamp the filter cigarette 21.

[0038] By designing the elastic tube 15, the telescopic cylinder 16, and the abutting block 17, on the one hand, it is ensured that the filter end of the cigarette with filter tip 21 can be tightly inserted into the inner side of the elastic tube 15, and there will be no air leakage between the filter tip of the cigarette with filter tip 21 and the inner wall of the elastic tube 15; on the other hand, the telescopic cylinder 16 can drive the abutting block 17 to press against the cigarette with filter tip 21 inside the elastic tube 15, so that the cigarette with filter tip 21 will not fall out of the elastic tube 15 when air is filled into the sleeve 14.

[0039] By designing the second conveying mechanism, the filter cigarettes 21 that have completed the tobacco separation can be reliably transferred and stored.

[0040] The following are some examples of automatic tobacco-to-cigarette separation devices:

[0041] See appendix Figure 1-5 This is a schematic diagram of the overall and partial structure of one embodiment of the present utility model. The present utility model specifically discloses an automatic tobacco and tobacco tube separation device, which separates the tobacco in the filter cigarette 21 from the tobacco tube. The filter cigarette 21 includes a tobacco tube, a filter and tobacco. One end of the tobacco tube is connected to the filter and the tobacco tube is filled with tobacco.

[0042] The separation device includes a frame 1, a conveying mechanism, a conveying mechanism 1, and an air blowing assembly.

[0043] The frame 1 is equipped with a tobacco chamber 2 and a placement plate 3. The tobacco chamber 2 contains multiple filter cigarettes 21 with tobacco to be separated. The rectangular placement plate 3 is horizontally arranged and has elongated holes 30 on its surface.

[0044] The conveying mechanism is installed on the frame 1. The conveying mechanism sequentially conveys multiple filter cigarettes 21 in the cigarette chamber 2 to the placement plate 3. That is, the conveying mechanism can deliver one filter cigarette 21 in the cigarette chamber 2 to the upper surface of the placement plate 3 at a time. The length direction of the filter cigarette 21 on the placement plate 3 is the same as the length direction of the elongated hole 30, and the length of the elongated hole 30 is greater than the length of the filter cigarette 21.

[0045] The first conveying mechanism includes a telescopic cylinder 9, a lower mounting frame 10, an upper mounting frame 11, an abutment wheel 12, and a drive motor 13. Of course, in other embodiments, the first conveying mechanism can also be a horizontal conveyor belt mechanism or a mechanical gripper, as long as it can grab and drive the filter cigarette 21 to move horizontally and insert it into the sleeve 14, which is not limited here.

[0046] Telescopic cylinder 9 is vertically fixed to frame 1; lower mounting frame 10 is located above telescopic cylinder 9, and is fixed to the vertical telescopic end of telescopic cylinder 9, allowing telescopic cylinder 9 to drive lower mounting frame 10 to move up and down; upper mounting frame 11 is fixed to placement plate 3; multiple abutment wheels 12 are horizontally rotatably supported on both lower mounting frame 10 and upper mounting frame 11; the multiple abutment wheels 12 on lower mounting frame 10 and multiple abutment wheels 12 on upper mounting frame 11 are arranged sequentially along the length of the elongated hole 30. Multiple abutting wheels 12 located on the lower mounting frame 10 are vertically aligned with multiple abutting wheels 12 located on the upper mounting frame 11. The axis of the abutting wheel 12 is perpendicular to the length direction of the elongated hole 30. Each abutting wheel 12 has an annular limiting groove 120 coaxially on its outer side wall. The width of the annular limiting groove 120 is smaller than the outer diameter of the cross-section of the cigarette with filter tip 21. As the telescopic cylinder 9 drives the lower mounting frame 10 to move up and down, the abutting wheel 12 installed on the lower mounting frame 10 can be located in the elongated hole 30.

[0047] Multiple abutting wheels 12 on the lower mounting frame 10 and multiple abutting wheels 12 on the upper mounting frame 11 can jointly clamp a filter cigarette 21 on the placement plate 3. The center line of the filter cigarette 21 on the placement plate 3 is centrally located between the two side walls of the annular limiting groove 120. Due to the annular limiting groove 120, the abutting wheels 12 can reliably limit the filter cigarette 21. The drive motor 13 is fixed to the upper mounting frame 11 and is connected to the abutting wheels 12 on the upper mounting frame 11. The drive motor 13 drives the abutting wheels 12 on the upper mounting frame 11 to rotate, and the filter cigarette 21 clamped by the abutting wheels 12 on the lower mounting frame 10 and the abutting wheels 12 on the upper mounting frame 11 will move horizontally.

[0048] The blowing assembly includes a sleeve 14 with a circular inner profile. The sleeve 14 is horizontally fixed on the frame 1. The length direction of the sleeve 14 is the same as the length direction of the elongated hole 30. The sleeve 14 is located on one side of the placement plate 3 with one end open and the other end closed. The closed end of the sleeve 14 is open and connected to an external high-pressure air source. A valve body is connected in series between the two to control the opening and closing of the air passage. When the drive motor 13 is activated, the filter cigarette 21, which is clamped by the abutment wheel 12 on the lower mounting frame 10 and the abutment wheel 12 on the upper mounting frame 11, will move horizontally. The filter end of the filter cigarette 21 can be tightly inserted into the sleeve 14. After the filter tip of the cigarette with filter tip 21 is inserted into the sleeve 14, the valve body is opened, and the external high-pressure gas source quickly fills the sleeve 14 with gas. The high-pressure gas in the sleeve 14 will pass through the filter tip of the cigarette with filter tip 21 and blow the tobacco out of the cigarette, thereby achieving the separation of the tobacco from the cigarette.

[0049] According to the embodiment of this utility model, the automatic tobacco-to-cigarette separation device, through the design of a tobacco chamber 2, a placement plate 3, and a conveying mechanism, allows the conveying mechanism to smoothly transport the filter-tipped cigarettes 21 from the tobacco chamber 2 to the placement plate 3. The conveying mechanism also allows the filter-tipped cigarettes 21 to be horizontally transported a certain distance, ensuring that the filter tip of the cigarette 21 can be smoothly inserted into the sleeve 14. By designing the sleeve 14 to connect to an external high-pressure gas source, the filter-tipped cigarettes 21 can be inserted into the sleeve 14. The external high-pressure gas source fills the sleeve 14 with high-pressure gas, which passes through the filter tip of the cigarette 21 and blows out the tobacco from the cigarette, thus achieving the separation of the cigarette and tobacco from the filter. This separation device is simple and reliable; the tobacco in the filter-tipped cigarette 21 can be completely blown out; and the sleeve 14 fixes the cigarette with the filter, preventing deformation, resulting in a high yield of qualified empty cigarettes.

[0050] The conveying mechanism includes a cover 4, a guide roller 5, a reduction motor 6, and a discharge plate 7. The cover 4 is fixed to the frame 1. The cover 4 has a first strip hole 40 and a second strip hole 41. The length direction of the first strip hole 40 and the length direction of the second strip hole 41 are both parallel to the length direction of the long strip hole 30. The length of the first strip hole 40 is the same as the length of the second strip hole 41. The first strip hole 40 is located above the second strip hole 41.

[0051] The cigarette compartment 2 is funnel-shaped and its small diameter end is fixed to the cover body 4. The small diameter end of the cigarette compartment 2 is connected to the strip-shaped hole 40. The filter cigarette 21 in the cigarette compartment 2 can pass through the strip-shaped hole 40 by gravity.

[0052] A cylindrical guide roller 5 is horizontally rotatably supported inside the cover 4. The axis of the guide roller 5 is parallel to the length direction of the elongated hole 30. The guide roller 5 is located between the first elongated hole 40 and the second elongated hole 41. The placement plate 3 is located below the guide roller 5. The outer wall of the guide roller 5 is parallel to the inner wall of the cover 4 and has a gap. The gap is smaller than the outer diameter of the cross-section of the cigarette with filter tip 21. Multiple material grooves 50 are opened on the outer wall of the guide roller 5. The multiple material grooves 50 are circumferentially aligned with the guide roller 5. The material troughs are evenly arranged, with the length of the trough 50 parallel to the axis of the guide roller 5. The material trough 50 can be directly aligned with the position of the first strip hole 40 or the second strip hole 41. When the guide roller 5 rotates to the position where a material trough 50 is directly aligned with the first strip hole 40, a cigarette with a filter tip 21 in the cigarette chamber 2 can enter the material trough 50. During the process of the guide roller 5 driving the cigarette with a filter tip 21 in the material trough 50 to rotate, the cigarette with a filter tip 21 in the material trough 50 will not fall out due to the cover 4.

[0053] The geared motor 6 is fixed to the cover 4 and its output shaft is fixed coaxially with the guide roller 5. The geared motor 6 can reliably drive the guide roller 5 to rotate.

[0054] The discharge plate 7 is arranged at an angle relative to the horizontal plane. The upper end of the discharge plate 7 is fixed to the cover 4, and the lower end of the discharge plate 7 is connected to the placement plate 3. The second strip hole 41 is located above the discharge plate 7. As the guide roller 5 rotates, the material trough 50 containing the filter cigarette 21 will correspond to the position of the second strip hole 41. At this time, the filter cigarette 21 in the material trough 50 will pass through the second strip hole 41 due to gravity and fall onto the discharge plate 7. Since the discharge plate 7 is arranged at an angle relative to the horizontal plane and the lower end is connected to the placement plate 3, the filter cigarette 21 that falls out of the second strip hole 41 will roll diagonally downward onto the placement plate 3.

[0055] The length direction of the filter cigarettes 21 located in the cigarette chamber 2 is the same as that of the guide roller 5. The filter ends of the filter cigarettes 21 located in the cigarette chamber 2 are all arranged close to the sleeve 14. The filter cigarettes 21 in the cigarette chamber 2 can be reliably arranged to ensure that the filter ends of the subsequent filter cigarettes 21 can be smoothly inserted into the sleeve 14.

[0056] The conveying mechanism also includes a baffle 8, which is arranged vertically and its upper end is fixed to the upper mounting frame 11. The lower end of the baffle 8 is fixed to the placement plate 3. The elongated hole 30 is located between the baffle 8 and the discharge plate 7. The filter cigarette 21 located on the placement plate 3 can abut against the baffle 8. By designing the baffle 8, when the filter cigarette 21 falls out of the elongated hole 41 and rolls diagonally downward, the baffle 8 can limit it, ensuring that the filter cigarette 21 can roll to the position corresponding to the elongated hole 30.

[0057] More specifically, the blowing assembly also includes an elastic tube 15, a telescopic cylinder 16, and abutment block 17. The elastic tube 15 is coaxially arranged inside the sleeve 14, and both ends of the elastic tube 15 are sealed and fixed to the inner wall of the sleeve 14. That is, the high-pressure gas flowing into the sleeve 14 will not enter between the inner wall of the sleeve 14 and the outer wall of the elastic tube 15. The inner diameter of the elastic tube 15 is equal to the outer diameter of the cross-section of the filter cigarette 21. However, due to the elasticity of the elastic tube 15 itself, the filter end of the filter cigarette 21 located on the placement plate 3 can be tightly inserted into the elastic tube 15. The sleeve 14 is horizontally arranged and its outer wall is provided with a clearance hole 140. The hole 140 corresponds to the position of the elastic tube 15; the telescopic cylinder 16 is fixed on the frame 1, and the abutment block 17 is fixed to the vertical telescopic end of the telescopic cylinder 16. The abutment block 17 can be arranged in the clearance hole 140. When the filter end of the cigarette with filter tip 21 is inserted into the elastic tube 15, the telescopic cylinder 16 drives the abutment block 17 to rise. The upper end of the abutment block 17 can pass through the clearance hole 140 and press against the outer wall of the elastic tube 15. The elastic tube 15 deforms, and the filter section of the cigarette with filter tip 21 located inside the elastic tube 15 can be reliably squeezed to prevent the cigarette with filter tip 21 from coming out of the elastic tube 15 when the high-pressure gas is rapidly filled into the sleeve 14.

[0058] More specifically, the automatic tobacco and tobacco pipe separation device also includes a second conveying mechanism, which includes guide rollers 18, a conveyor belt 19, and a second drive motor 20. Two guide rollers 18 are horizontally rotatably supported on the frame 1, and the axis of the two guide rollers 18 is the same as the length direction of the elongated hole 30. The second drive motor 20 is fixed to the frame 1, and the output shaft of the second drive motor 20 is coaxially fixed with one of the guide rollers 18. The conveyor belt 19, which is closed at both ends, is simultaneously fitted onto the two guide rollers 18. The conveyor belt 19 is provided with multiple elongated through holes 190, which are arranged equidistantly along the length direction of the conveyor belt 19. The length direction of the through holes 190 is the same as the width direction of the conveyor belt 19, and the length of the through holes 190 is less than the length of the cigarette with filter tip 21. The telescopic cylinder 9 is located inside the conveyor belt 19, and the lower mounting frame 10 and multiple abutment wheels 12 located on the lower mounting frame 10 can pass through the through holes 190 and move to the inside of the conveyor belt 19.

[0059] A storage bin with an open top is placed on the frame 1. The storage bin is located below one end of the conveyor belt 19. Filtered cigarettes 21 with tobacco shreds separated on the conveyor belt 19 will fall into the storage bin for collection.

[0060] The filter tip of the cigarette with filter tip 21 is inserted into the elastic tube 15. After the sleeve 14 is filled with air, the tobacco in the cigarette with filter tip 21 is blown out.

[0061] After the tobacco is separated from the cigarette tube, the drive motor 13 rotates in the opposite direction. The cigarette with filter tip 21, which has completed the separation of tobacco, will move horizontally in the opposite direction and reset. That is, the cigarette with filter tip 21, which has completed the separation of tobacco, will be pulled out from the elastic tube 15 and moved to be directly opposite the position of the elongated hole 30.

[0062] After the filtered cigarette 21, which has completed tobacco separation, is reset, the telescopic cylinder 9 drives the lower mounting frame 10 to move down. Since the length of the through hole 190 is less than the length of the filtered cigarette 21, the filtered cigarette 21, which has completed tobacco separation, will be intercepted on the conveyor belt 19 as it moves down with the lower mounting frame 10.

[0063] After the lower mounting frame 10 and the multiple abutment wheels 12 located on the lower mounting frame 10 are moved to the inside of the conveyor belt 19, the movement of the conveyor belt 19 will drive the filter cigarettes 21 that have completed tobacco separation to move into the storage box.

[0064] The conveyor belt 19 is provided with multiple slots 191, which are arranged equidistantly along the length of the conveyor belt 19. Each slot 191 has a through hole 190 on its bottom wall. The length of the slot 191 is the same as the length of the through hole 190. Each slot 191 can hold a filter cigarette 21. The slots 191 can limit the movement of the filter cigarette 21 after the tobacco has been separated, preventing the filter cigarette 21 from moving randomly on the upper surface of the conveyor belt 19.

[0065] The output shaft of the drive motor 13 is coaxially fixed with an abutment wheel 12 located on the upper mounting bracket 11 and closest to the sleeve 14, that is, an abutment wheel 12 on the upper mounting bracket 11 is a drive wheel.

[0066] After the filtered cigarette 21 rolls onto the upper surface of the placement plate 3, due to the design of the elongated hole 30 and the lower mounting frame 10 with abutment wheels 12 located inside the elongated hole 30, the filtered cigarette 21 will be arranged in the elongated hole 30 and abut against the multiple abutment wheels 12 on the lower mounting frame 10. That is, the multiple abutment wheels 12 on the lower mounting frame 10 will support the filtered cigarette 21 and prevent the filtered cigarette 21 from falling out of the elongated hole 30.

[0067] The filter tip of the cigarette with filter tip 21 is arranged close to the sleeve 14. The filter tip of the cigarette with filter tip 21 has a certain length. When the cigarette with filter tip 21 moves horizontally forward or backward along the length direction of the sleeve 14, the abutting wheel 12 located on the upper mounting frame 11 and closest to the sleeve 14 and the abutting wheel 12 located on the lower mounting frame 10 and closest to the sleeve 14 will always clamp the filter tip of the cigarette with filter tip 21, ensuring that after the tobacco is separated, the cigarette with filter tip 21 can move smoothly in the reverse direction to be directly opposite the position of the elongated hole 30.

[0068] In this application, telescopic cylinder 9 and telescopic cylinder 16 are both electric cylinders. A controller is fixed on the frame 1. The valve body, telescopic cylinder 9, telescopic cylinder 16, geared motor 6, drive motor 13 and drive motor 20 are all electrically connected to the controller.

[0069] When the separation device is in operation:

[0070] In the initial state, the valve body is closed, the geared motor 6, drive motor 13 and drive motor 20 are all stopped, the telescopic cylinder 9 is extended, the highest point of the abutment wheel 12 on the lower mounting frame 10 is flush with the upper surface of the placement plate 3, the telescopic cylinder 2 16 is retracted, one material groove 50 on the guide roller 5 is aligned with the strip hole 40, and one material groove 50 on the guide roller 5 is aligned with the strip hole 41.

[0071] First, multiple cigarettes with filters 21 are placed into the cigarette chamber 2. One of the cigarettes with filters 21 in the cigarette chamber 2 will enter the material trough 50 corresponding to the first strip hole 40. Then, the reduction motor 6 is started. The reduction motor 6 drives the guide roller 5 to rotate intermittently. That is, the reduction motor 6 drives the guide roller 5 to rotate a certain angle and then stops for a period of time. Each time the guide roller 5 stops, there is always one material trough 50 that is directly opposite the first strip hole 40 and one material trough 50 that is directly opposite the second strip hole 41. When the material trough 50 containing the cigarette with filters 21 is directly opposite the second strip hole 41, the cigarette with filters 21 in the material trough 50 will roll onto the placement plate 3.

[0072] The second step is that after the guide roller 5 stops rotating, the telescopic cylinder 9 drives the lower mounting frame 10 to move up a certain height, so that the multiple abutting wheels 12 on the lower mounting frame 10 and the multiple abutting wheels 12 on the upper mounting frame 11 together clamp a filter cigarette 21 on the placement plate 3.

[0073] Third step, after the telescopic cylinder 9 completes the upward movement, the drive motor 13 starts and drives the abutment wheel 12 to rotate forward. The filter cigarette 21 clamped by the abutment wheel 12 will move horizontally a certain distance along the length of the sleeve 14, and the filter end of the filter cigarette 21 will be inserted into the elastic tube 15.

[0074] Fourth step: After the filter tip of the cigarette with filter tip 21 is inserted into the elastic tube 15, the telescopic cylinder 2 16 drives the abutment block 17 to move upward a certain distance, and the abutment block 17 presses the cigarette with filter tip 21 inserted into the inner side of the elastic tube 15.

[0075] Fifth step: the valve body is opened for a certain period of time, and the external high-pressure gas source fills the sleeve 14 with gas. The tobacco in the filter cigarette 21 is blown out by the high-pressure gas in the sleeve 14, thereby completing the separation of tobacco.

[0076] In the sixth step, the drive motor 13 starts again and drives the abutment wheel 12 to reverse. The filter cigarette 21 that has completed the tobacco separation will move horizontally in the opposite direction along the tube length of the sleeve 14 for a certain distance until the filter cigarette 21 that has completed the tobacco separation is directly opposite to the position of the long strip hole 30.

[0077] Step 7: Telescopic cylinder 19 drives the lower mounting frame 10 to move down a certain distance. The filter cigarettes 21 with tobacco shreds that have been separated will be intercepted on the conveyor belt 19 as the lower mounting frame 10 moves down. After the lower mounting frame 10 and the multiple abutting wheels 12 located on the lower mounting frame 10 have moved to the inside of the conveyor belt 19, the drive motor 20 drives the conveyor belt 19 to move a certain distance. The conveyor belt 19 will move the filter cigarettes 21 with tobacco shreds that have been separated into the storage box.

[0078] In the eighth step, after the conveyor belt 19 moves a certain distance, a through hole 190 on the conveyor belt 19 will be aligned with the position of the lower mounting frame 10. At this time, the telescopic cylinder 19 will drive the lower mounting frame 10 to move upward until the highest point of the abutment wheel 12 on the lower mounting frame 10 is flush with the upper surface of the placement plate 3. The second to eighth steps are completed within the time period when the guide roller 5 stops rotating in the first step.

[0079] The test showed that the separation device could separate 15 cigarettes with filters per minute, achieving a pass rate of 93%.
