Description

Technical Field

[0001] The invention relates to the technical field of tobacco shred separation, and in particular to a tobacco shred radial separation device. Background Art

[0002] Heat-not-burn cigarettes do not burn, but directly heat tobacco products through electric heating devices to bake out the aromatic substances in tobacco, avoiding the generation of harmful substances and sidestream smoke caused by high-temperature combustion of cigarettes. Heated cigarette products generally use a needle-type heating method. The temperature at different distances from the heating needle is different, and the content of substances baked out in the tobacco is also different. In order to study the distribution of the main components in the tobacco after heating, the tobacco needs to be layered and peeled off. By analyzing the components of each layer of tobacco, the radial distribution law of the main components in the tobacco can be mastered. However, in the existing technology, only tobacco and cigarette holder paper can be separated, and radial separation of tobacco cannot be performed, which cannot support this research.

At present, the recycling of defective cigarettes mostly relies on air blowing and manual cutting to separate cigarette holders, which is labor-intensive and extremely inefficient. Based on this situation, a waste cigarette separator is invented. The present invention is a system for automatically separating tobacco shreds from cigarette holders and cigarette papers. The feeder is generally used to automatically arrange the cigarettes into rows and output them, and the vibrating screen further separates the cigarettes cut by the camera automatic cutting system, and the separated tobacco shreds and cigarette holders and cigarette papers are automatically discharged. The present invention is simple to operate, and only needs to manually add waste cigarettes to the feeder, with a high degree of automation and reduced manual labor. The invention realizes the function of replacing manual labor with a machine, solves the uncontrollable factors such as work emotionality caused by excessive fatigue due to large workload when manually separating tobacco shreds, increases the quality control rate, and has the advantages of low cost and high efficiency. However, the waste cigarette processor can only separate tobacco shreds from cigarette holders and cigarette papers, and cannot achieve the separation of tobacco shreds at different radial positions.

[0014] The tobacco radial separation device of the present invention has the following gain effects:

[0015] (1) The separation device first places the cigarette holder from which tobacco shreds need to be separated into the first cavity through the opening at the bottom of the separation sleeve, and then screws the receiving tube to the bottom of the separation sleeve to close the opening of the separation sleeve. A first through hole is provided at the top of the separation sleeve, which is plugged into the first through hole through a push rod. When the push rod moves downward, it will abut against the tobacco shreds in the center of the cigarette holder. When it continues to move downward, it will drive part of the tobacco shreds in contact with the push rod to separate from the cigarette holder, and then pass through the second through hole of the receiving tube and enter the second cavity for collection. When it is necessary to peel off tobacco shreds at different radial positions of the cigarette holder, it is only necessary to replace push rods of different diameters, as well as the separation sleeve corresponding to the first through hole diameter and the receiving tube corresponding to the second through hole diameter. In this way, tobacco shreds at various radial positions of the cigarette holder can be separated, so as to study the distribution of the main components in the tobacco shreds after heating;

[0016] (2) The separation sleeve of the separation device is provided with a first separation part and a second separation part, a first through hole is provided on the first separation part, a third through hole is provided on the second separation part, the first separation part is plugged into the third through hole, a first cavity is provided at the bottom of the first separation part and the second separation part, the push rod includes a first push part plugged into the first through hole and a second push part connected to the first push part at one end and having a cross-sectional diameter greater than the cross-sectional diameter of the first push part, the cross-sectional diameter of the second push part is less than or equal to the cross-sectional diameter of the first separation part, and the receiving barrel includes a first barrel having a second through hole with the same diameter as the inner diameter of the first separation part and a second barrel having a second through hole with the same diameter as the outer diameter of the first separation part. The separation sleeve is arranged to be composed of two parts, the upper layer includes the first separation part and the second separation part, the lower layer is provided with a first cavity for accommodating the cigarette holder, the push rod is also composed of the first push part and the second push part, the first separation part is provided with a first through hole for plugging the first push part, and the second separation part is provided with a third through hole for plugging the first separation part. When separating tobacco shreds, first put the cigarette holder from which tobacco shreds need to be separated into the first cavity from the opening at the bottom of the separation sleeve, then screw the first barrel to the bottom of the separation sleeve to close the opening of the separation sleeve, the first separation portion is sleeved in the first separation portion through the third through hole, the first pushing portion is plugged into the first through hole, and penetrates through the first through hole to abut against the inner layer of tobacco shreds in the cigarette holder in the first cavity, when the push rod continues to move downward, the first pushing portion squeezes the inner layer of tobacco shreds, thereby driving the inner layer of tobacco shreds to separate from the cigarette holder, until the inner layer of tobacco shreds is pushed into the second cavity of the first barrel through the second through hole;

[0017] (3) The first through hole and the third through hole of the separation device are both threaded holes, the first separation portion is provided with an external thread that is threadedly connected to the third through hole, the first pushing portion is provided with an external thread that is threadedly connected to the first through hole, the second pushing portion is provided with an external thread that is threadedly connected to the third through hole, the first separation portion is provided with a limiting groove, the separation sleeve is provided with a limiting hole with the same shape as the limiting groove, and also includes a limiting block with one end passing through the limiting hole and plugged into the limiting groove. The first separation part and the second separation part are connected, and the first pushing part and the first separation part are connected in a screw-connected structure. At the same time, the cross-sectional diameter of the second pushing part is set to be equal to the cross-sectional diameter of the first separation part. When the second pushing part drives the first separation part to move downward, the second pushing part and the second separation part are connected in a screw-connected manner. The screw-connected manner is adopted, on the one hand, because the separation of tobacco shreds is achieved by pressing down the push rod. Since the bottom of the push rod is a plane, it is necessary to apply a large force on the push rod in order to separate the tobacco shreds by pressing down the push rod, thereby affecting the use effect of the device. The screw-connected manner is adopted, and the first pushing part cooperates with the first separation part, and the second pushing part and the When the second separation part cooperates, the first separation part and the second separation part will exert a force on the push rod, so that the downward movement of the push rod can be realized more easily, making the use of the device more labor-saving; on the other hand, the first cavity accommodates the cigarette holder, and when the first pushing part and the second pushing part respectively drive the inner layer of tobacco and the middle layer of tobacco to move downward into the first cavity, since there is no structure in the first cavity to guide the first pushing part and the second pushing part, this will result in the push rod being unable to ensure coaxial movement when moving downward, resulting in deviation in the position of the separated tobacco, and further causing inaccurate research results, while through the screw connection, the cooperation of the thread will limit the push rod, so that the downward movement of the push rod is more stable, and no axis deviation will occur;

[0018] (4) The material receiving barrel of the separation device includes an abutting portion screwed to the bottom of the separation sleeve, and a material receiving portion screwed to the bottom of the abutting portion, the second through hole is provided on the abutting portion, and the second cavity is provided in the material receiving portion. In the present application, the function of the material receiving barrel is, on the one hand, to collect the separated tobacco shreds, and on the other hand, to close the opening of the separation sleeve to prevent the entire cigarette holder from moving with the push rod when the push rod moves downward, thereby failing to achieve the purpose of separation. Therefore, the material receiving barrel is a closed structure except for the second through hole for receiving the material. This will lead to a problem, that is, after the tobacco shreds enter the second cavity of the material receiving barrel through the second through hole, it is inconvenient to take the tobacco in the second cavity. Therefore, in the present application, the material receiving barrel is configured to be composed of an abutting portion screwed to the bottom of the separation sleeve and a material receiving portion screwed to the bottom of the abutting portion, the second through hole is arranged on the abutting portion, and the second cavity is arranged in the material receiving portion. After the separated tobacco shreds enter the second cavity of the material receiving portion through the second through hole of the abutting portion, the material receiving portion is removed from the abutting portion, and the tobacco shreds can be directly taken, which is convenient and quick.

[0019] (5) The separation device also includes a handle connected to the other end of the second push part, and a friction part is provided on the handle to increase the friction force. In the present application, the separation of tobacco shreds is achieved by squeezing different positions of the cigarette holder by moving the push rod downward. Therefore, a handle is connected to the other end of the push rod to facilitate the operation of moving the push rod downward. At the same time, a friction part is provided on the handle to increase the friction force between the hand and the handle, so that the downward movement of the push rod is easier to operate;

[0020] (6) The first separation part of the separation device is provided with a first marking part, and the second separation part is provided with a corresponding second marking part. The first separation part is provided with a first marking part, and the second separation part is provided with a corresponding second marking part because when the first push part drives the first separation part to move upward and returns the first separation part to its original position before separation, it is difficult to make the first separation part coincide with its original position before separation without a reference mark. When the tobacco is separated and the first separation part is reset, the second separation part is fixed. Therefore, when the first separation part rises to the point where the first marking part is aligned with the second marking part, it can be known that the first separation part has returned to its original position.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] A tobacco radial separation device according to an embodiment of the present invention is used to strip tobacco from a cigarette holder 4 in layers, comprising a separation sleeve 1 for accommodating the cigarette holder 4, a push rod 2 plugged into the top of the separation sleeve 1 and used to squeeze the cigarette holder 4 to strip the tobacco in layers when the separation sleeve 1 moves downward, and a receiving barrel 3 screwed to the bottom of the separation sleeve 1 and used to receive the stripped tobacco; a first cavity 11 for accommodating the cigarette holder 4 is provided in the separation sleeve 1, the bottom of the separation sleeve 1 is open, and a first through hole 121 for inserting the push rod 2 is provided at the top, a second cavity 321 for accommodating the stripped tobacco is provided in the receiving barrel 3, and a second through hole 311 for tobacco to enter the second cavity 321 is provided at the top of the receiving barrel 3, and the specific effect is shown in FIG. Figure 1 .

[0034] The present application first places the cigarette holder 4 from which the tobacco shreds need to be separated into the first cavity 11 from the opening at the bottom of the separation sleeve 1, and then screws the material receiving tube 3 to the bottom of the separation sleeve 1 to close the opening of the separation sleeve 1. The top of the separation sleeve 1 is provided with a first through hole 121, which is plugged into the first through hole 121 through a push rod 2. When the push rod 2 moves downward, it will contact the tobacco shreds at the center of the cigarette holder 4. When it continues to move downward, it will drive the part of the tobacco shreds in contact with the push rod 2 to separate from the cigarette holder 4, and then pass through the second through hole 311 of the material receiving tube 3 to enter the second cavity 321 for collection. When it is necessary to strip the tobacco shreds at different radial positions of the cigarette holder 4, it is only necessary to replace the push rod 2 of different diameters, and replace the separation sleeve 1 corresponding to the diameter of the first through hole 121 and the material receiving tube 3 corresponding to the diameter of the second through hole 311, so that the tobacco shreds at various radial positions of the cigarette holder 4 can be separated, thereby studying the distribution of the main components in the tobacco shreds after heating.

[0035] In this embodiment, a first separation portion 12 and a second separation portion 13 are provided in the separation sleeve 1, a first through hole 121 is provided on the first separation portion 12, a third through hole 131 is provided on the second separation portion 13, the first separation portion 12 is plugged into the third through hole 131, the first cavity 11 is provided at the bottom of the first separation portion 12 and the second separation portion 13, the push rod 2 includes a first pushing portion 21 plugged into the first through hole 121 and a second pushing portion 22 connected to the first pushing portion 21 at one end and having a cross-sectional diameter greater than the cross-sectional diameter of the first pushing portion 21, the cross-sectional diameter of the second pushing portion 22 is less than or equal to the cross-sectional diameter of the first separation portion 12, the receiving barrel 3 includes a first barrel having a second through hole 311 with the same aperture as the inner diameter of the first separation portion 12 and a second barrel having a second through hole 311 with the same aperture as the outer diameter of the first separation portion 12, the specific effect is shown in FIG. Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The separation sleeve 1 is configured to consist of two parts, the upper layer includes a first separation part 12 and a second separation part 13, the lower layer is provided with a first cavity 11 for accommodating the cigarette holder 4, the push rod 2 is also composed of a first push part 21 and a second push part 22, the first separation part 12 is provided with a first through hole 121 for the first push part 21 to be inserted, the second separation part 13 is provided with a third through hole 131 for the first separation part 12 to be inserted, and the second separation part 13 and the main body of the separation sleeve 1 are an integrated structure. When separating tobacco shreds, first put the cigarette holder 4 from which tobacco shreds need to be separated into the first cavity 11 through the opening at the bottom of the separation sleeve 1, then screw the first barrel to the bottom of the separation sleeve 1, and close the opening of the separation sleeve 1. The first separation portion 12 is sleeved in the first separation portion 12 through the third through hole 131, and the first pushing portion 21 is plugged into the first through hole 121, and penetrates the first through hole 121 to abut against the inner layer of tobacco shreds in the cigarette holder 4 in the first cavity 11. When the push rod 2 continues to move downward, the first pushing portion 21 will squeeze the inner layer of tobacco shreds, thereby driving the inner layer of tobacco shreds to separate from the cigarette holder 4, until the inner layer of tobacco shreds are pushed into the second cavity 321 of the first barrel through the second through hole 311.

[0036] Since the cross-sectional diameter of the second pushing portion 22 is larger than the cross-sectional diameter of the first pushing portion 21 and smaller than or equal to the cross-sectional diameter of the first separating portion 12, when the first pushing portion 21 pushes the inner layer of tobacco into the second cavity 321 of the first barrel, the second pushing portion 22 abuts against the first separating portion 12. At this time, the first barrel that has collected the inner layer of tobacco is removed from the separating sleeve 1, and the second barrel is replaced. The push rod 2 is continuously pushed, so that the second pushing portion 22 drives the first separating portion 12 to move downward, so that the first separating portion 12 squeezes the middle layer of tobacco in the cigarette holder 4, thereby driving the middle layer of tobacco and the cigarette holder. 4 is separated until the middle layer of tobacco shreds is pushed into the second cavity 321 of the second barrel. Since the first pushing part 21 also continues to move downward when the second pushing part 22 drives the first separating part 12 to move downward, the length of the second cavity 321 in the second barrel should be set to be greater than the length of the second cavity 321 in the first barrel in order for the first separating part 12 to push the middle layer of tobacco shreds into the second barrel. Finally, the second barrel is removed from the separating sleeve 1, the cigarette holder 4 after the tobacco shreds in the first cavity 11 are taken out, and the cigarette paper of the cigarette holder 4 is torn open, so that tobacco shreds at three different radial positions of the cigarette holder 4 can be obtained respectively.

[0037] The present device is configured with such a structure because it is possible to separate multiple layers of tobacco from the cigarette holder 4 only by replacing the material receiving cylinder 3 without replacing the push rod 2 and the separation sleeve 1. If one wants to separate the tobacco from the cigarette holder 4 into four layers, five layers or more layers, it is only necessary to set a third separation portion, a fourth separation portion and more separation portions on the separation sleeve 1, and to set a third pushing portion, a fourth pushing portion and more pushing portions on the push rod 2. Compared with the previous need to replace the separation sleeve 1, the push rod 2 and the material receiving cylinder 3, this structure saves time and effort and can reduce the processing cost of the present device, thereby improving the practicality of the present application.

[0038] The first through hole 121 and the third through hole 131 are both threaded holes, the first separation portion 12 is provided with an external thread screwed to the third through hole 131, the first pushing portion 21 is provided with an external thread screwed to the first through hole 121, the second pushing portion 22 is provided with an external thread screwed to the third through hole 131, the first separation portion 12 is provided with a limiting groove 122, the separation sleeve 1 is provided with a limiting hole 14 with the same shape as the limiting groove 122, and also includes a limiting block 5 with one end passing through the limiting hole 14 and plugged into the limiting groove 122. For specific effects, see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The first separation part 12 and the second separation part 13 are connected, and the first pushing part 21 and the first separation part 12 are connected to each other in a screw connection structure. At the same time, the cross-sectional diameter of the second pushing part 22 is set to be equal to the cross-sectional diameter of the first separation part 12. When the second pushing part 22 drives the first separation part 12 to move downward, the second pushing part 22 and the second separation part 13 are connected in a screw connection. The screw connection is adopted because, on the one hand, the separation of tobacco shreds is achieved by pressing down the push rod 2. Since the bottom of the push rod 2 is a plane, it is necessary to apply a large force on the push rod 2 to separate tobacco shreds by pressing down the push rod 2, thereby affecting the use effect of the device. By adopting the screw connection method, the first pushing part 21 cooperates with the first separation part 12, and the second pushing part 2 2 cooperates with the second separation part 13, the first separation part 12 and the second separation part 13 will apply a force to the push rod 2, so that the downward movement of the push rod 2 is easier to achieve, making the use of the device more labor-saving; on the other hand, the first cavity 11 accommodates the cigarette holder 4. When the first pushing part 21 and the second pushing part 22 respectively drive the inner layer of tobacco and the middle layer of tobacco to move downward into the first cavity 11, since there is no structure in the first cavity 11 to guide the first pushing part 21 and the second pushing part 22, this will cause the push rod 2 to be unable to ensure coaxial movement when moving downward, thereby causing the position of the separated tobacco to deviate, and further causing inaccurate research results. By means of screw connection, the cooperation of the thread will limit the push rod 2, so that the downward movement of the push rod 2 is more stable and no axis deviation will occur.

[0039] In the screw connection mode, when the first pushing part 21 cooperates with the first separating part 12, and the second pushing part 22 cooperates with the second separating part 13, the first separating part 12 and the second separating part 13 will exert a force on the push rod 2, and at the same time, they will be subjected to a reaction force exerted by the push rod 2. Since the second separating part 13 and the main body of the separation sleeve 1 are integrated, there is no need to worry about the displacement of the second separating part 13. The first separating part 12 is screwed to the second separating part 13. When the first pushing part 21 is screwed to the first separating part 12 and moves downward, the first separating part 13 will be The separation portion 12 also moves downward, so that the bottom of the first pushing portion 21 cannot contact the inner layer of tobacco. At this time, the first separation portion 12 needs to be limited, so a limiting groove 122 is set on the first separation portion 12, and a limiting hole 14 is set on the main body of the separation sleeve 1. The limiting block 5 passes through the limiting hole 14 and is plugged into the limiting groove 122, so as to limit the first separation portion 12. When separating the middle layer of tobacco, the first separation portion 12 needs to be moved downward, and then the limiting block 5 and the limiting groove 122 are released so that they are no longer limited.

[0040] The material receiving barrel 3 includes an abutting portion 31 screwed to the bottom of the separation sleeve 1, and a material receiving portion 32 screwed to the bottom of the abutting portion 31, a second through hole 311 is provided on the abutting portion 31, and a second cavity 321 is provided in the material receiving portion 32. Figure 8 and Fig. 9 In the present application, the function of the receiving barrel 3 is to collect the separated tobacco shreds on the one hand, and to close the opening of the separation sleeve 1 on the other hand, to prevent the entire cigarette holder 4 from moving with the push rod 2 when the push rod 2 moves downward, thereby failing to achieve the purpose of separation. Therefore, except for the second through hole 311 for receiving the tobacco, the receiving barrel 3 is a closed structure, which will lead to a problem that after the tobacco shreds enter the second cavity 321 of the receiving barrel 3 through the second through hole 311, the tobacco shreds in the second cavity 321 It is inconvenient to take it, so in the present application, the material receiving cylinder 3 is configured to be composed of an abutment portion 31 screwed to the bottom of the separation sleeve 1 and a material receiving portion 32 screwed to the bottom of the abutment portion 31, the second through hole 311 is set on the abutment portion 31, and the second cavity 321 is set in the material receiving portion 32. After the separated tobacco shreds pass through the second through hole 311 of the abutment portion 31 and enter the second cavity 321 of the material receiving portion 32, the material receiving portion 32 is removed from the abutment portion 31, and the tobacco shreds can be directly taken, which is convenient and quick.

[0041] The rotation direction of the abutment portion 31 screwed to the bottom of the separation sleeve 1 is opposite to the rotation direction of the material receiving portion 32 screwed to the bottom of the abutment portion 31. In this device, the material receiving cylinder 3 is fixed to the separation sleeve 1 by screwing the abutment portion 31 to the bottom of the separation sleeve 1, and the material receiving portion 32 is screwed to the bottom of the abutment portion 31 to facilitate the removal of tobacco collected in the second cavity 321. If the rotation directions of the two when screwed are the same, when the material receiving cylinder 3 is fixed to the separation sleeve 1, if you want to take the tobacco in the second cavity 321, screw the material receiving portion 32 off the abutment portion 31, it is easy to make the abutment portion 31 also rotate with the material receiving portion 32, so that the abutment portion 31 is screwed off from the separation sleeve 1, which will make it difficult to take the tobacco. When the rotation directions of the two when screwed are opposite, screwing the material receiving portion 32 off the abutment portion 31 will not affect the screw connection between the abutment portion 31 and the separation sleeve 1.

[0042] The second through hole 311 of the first barrel is a threaded hole that can be screwed to the first push part 21, and the second through hole 311 of the second barrel is a threaded hole that can be screwed to the second push part 22. In order to enable the first push part 21 to better push the inner layer of tobacco into the second cavity 321 of the first barrel, and the second push part 22 to better push the middle layer of tobacco into the second cavity 321 of the second barrel, the first push part 21 and the second push part 22 must both extend part of the second cavity 321 through the second through hole 311 to ensure that the separated tobacco completely enters the second cavity 321. The second through hole 311 of the first barrel is set to be a threaded hole that can be screwed to the first push part 21, and the second through hole 311 of the second barrel is set to be screwed to the second push part 22. The threaded hole in which the moving part 22 is screwed, when the first pushing part 21 and the second pushing part 22 extend partly into the second cavity 321 through the second through hole 311, they will be screwed together with the second through hole 311. On the one hand, when screwed together, this arrangement will cause the material receiving barrel 3 to exert a force on the push rod 2, facilitating the downward movement of the push rod 2, thereby making the device more labor-saving. On the other hand, when the first pushing part 21 and the second pushing part 22 are screwed together with the second through hole 311, the second through hole 311 will limit them, thereby making the downward movement of the push rod 2 more stable and without causing the displacement of the axis.

[0043] The second pusher 22 further includes a handle 23 connected to the other end of the second pusher 22. The handle 23 is provided with a friction part for increasing the friction force. Figure 3 In the present application, the separation of tobacco shreds is achieved by squeezing different positions of the cigarette holder 4 by moving the push rod 2 downward, so a handle 23 is connected to the other end of the push rod 2 to facilitate the operation of moving the push rod 2 downward. At the same time, a friction part is provided on the handle 23 to increase the friction between the hand and the handle 23, so that the downward movement of the push rod 2 is easier to operate.

[0044] The first pushing part 21 is an expansion bolt, and the bottom of the first through hole 121 of the first separating part 12 is provided with a groove 124 which matches with the expansion bolt. Figure 6When the second pushing part 22 pushes the first separating part 12 to move downward, so that the middle layer of tobacco in the cigarette holder 4 is separated from the cigarette holder 4, until the middle layer of tobacco is pushed into the second cavity 321 of the receiving tube 3, the three layers of tobacco in the cigarette holder 4 can be separated. After the separation is completed, the first separating part 12 and the second separating part 13 are separated and enter the first cavity 11. If the device is to be used again, the push rod 2 needs to be removed from the separating sleeve 1, and then the first separating part 12 needs to be reconnected with the second separating part 13, which makes the repeated use of the device more troublesome. Therefore, the first pushing part 21 is configured as an expansion bolt, and a groove 124 cooperating with the expansion bolt is provided at the bottom of the first through hole 121 of the first separating part 12, because the inner layer of tobacco is separated. When the tobacco shreds are separated, the first pushing portion 21 has penetrated the first through hole 121. When the separation is completed, the push rod 2 can be moved upward. When the bottom of the first pushing portion 21 moves to the bottom of the first through hole 121, the expansion bolt cooperates with the groove 124, and the push rod 2 is moved upward again. The first pushing portion 21 will drive the first separation portion 12 to move upward together until the first separation portion 12 returns to its original position before separation. Since the separation of the inner layer of tobacco shreds starts from the first pushing portion 21 passing through the through hole, when the expansion bolt cooperates with the groove 124, the first pushing portion 21 always maintains a state of penetrating the first through hole 121, thereby saving the operation of pulling out the push rod 2 from the separation sleeve 1 and then plugging it in repeatedly, thereby saving time and energy for repeated use of the device.

[0045] The first separation portion 12 is provided with a first marking portion 123, and the second separation portion 13 is provided with a corresponding second marking portion 132. Figure 4 The first separation portion 12 is provided with a first marking portion 123, and the second separation portion 13 is provided with a corresponding second marking portion 132 because when the first pushing portion 21 drives the first separation portion 12 to move upward and returns the first separation portion 12 to its original position before separation, it is difficult to make the first separation portion 12 coincide with its original position before separation without a reference mark. When the tobacco is separated and the first separation portion 12 is reset, the second separation portion 13 is fixed. Therefore, when the first separation portion 12 rises to the point where the first marking portion 123 is aligned with the second marking portion 132, it can be known that the first separation portion 12 has returned to its original position.
