Description

Technical Field

[0001] This invention relates to a flexible conveying process device, specifically an improved flexible conveying process device for tobacco stems in the intelligent manufacturing of Yunyan Dazhongjiu cigarettes, belonging to the technical field of tobacco manufacturing equipment. Background Technology

[0002] Generally speaking, tobacco stems refer to the remaining stems and stalks during tobacco processing. In the tobacco manufacturing process, in order to facilitate the flexible transport of fragile tobacco stems between different processing stages and reduce breakage and damage during transport, pneumatic conveying is often used for flexible transport.

[0003] Currently, a search reveals that Chinese utility model patent CN208265331U discloses a negative pressure dilute phase pneumatic conveying system for reconstituted tobacco leaves. The system includes a feeding hopper, a vibrating conveyor, a duct inlet, a cyclone dust collector integrated with a silo, and a Roots blower. The feeding hopper is located at the front end of the vibrating conveyor, and the duct inlet is located at the rear end. The duct inlet is connected to the inlet of the cyclone dust collector integrated with the silo via an air inlet pipe. The outlet of the cyclone dust collector integrated with the silo is connected to the Roots blower via an exhaust pipe. The diameter of the air inlet pipe is less than [missing information]. Compared with existing technologies, this utility model achieves negative pressure dilute phase pneumatic conveying of raw materials such as reconstituted tobacco stems, tobacco leaves, and tobacco stalks, and also realizes loosening, impurity removal, flexible sorting, drying, cooling, and dust removal. At the same time, as a continuous material conveying equipment, it is conducive to realizing continuous and automated production. It is more flexible in layout and easier to maintain and manage than other conveying devices. However, during the use of this equipment, the tobacco stalks are directly conveyed by the vibrating conveying device, which may lead to uneven distribution and thickness of the tobacco stalks on the conveying device, thereby affecting the stability of the negative pressure gas conveying of the equipment.

[0004] Therefore, the key to solving the above-mentioned technical problems lies in developing a safe, reliable, and highly adaptable improved flexible equipment for the pneumatic conveying process of tobacco stems in the intelligent manufacturing of Yunyan Dazhongjiu cigarettes. Summary of the Invention

[0005] In view of the many defects and shortcomings of the above-mentioned background technology, the present invention has made improvements and innovations, aiming to provide a flexible, efficient, stable, reliable and automated improved Yunyan Dazhongjiu intelligent manufacturing tobacco stem pneumatic conveying flexible equipment, so as to realize the stability of the equipment in the conveying process and improve the conveying efficiency.

[0006] Another objective of this invention is to adjust the working height between the longitudinal and transverse feeding components and the conveying device through an adjustment mechanism, thereby adjusting the thickness of the tobacco stems on the surface of the conveying device to ensure the stability of the equipment during subsequent negative pressure conveying and to improve the applicability of the equipment.

[0007] Another objective of this invention is that the longitudinal feeding component can not only move and flatten the tobacco stems entering the surface of the conveying device, so that they move and are evenly distributed on the surface of the conveying device, preventing them from clumping and accumulating on the conveying device, thereby preventing the negative pressure conveying effect of the equipment from being affected, but also dry the tobacco stems while moving them, preventing them from clumping due to humidity, thereby reducing the clumping of tobacco stems during the conveying process and further improving the conveying effect of the equipment.

[0008] Another objective of this invention is to use a transverse feeding assembly to further move and flatten the tobacco stems, allowing them to move laterally within the conveying unit. This further ensures the uniformity of the tobacco stem distribution, thereby improving the conveying efficiency and stability of the equipment during use.

[0071] Among them, a spreading plate is also provided on the rectangular box (91) on the side away from the material spreading roller (812).

[0072] The working principle is as follows: Before using the above-mentioned improved Yunyan Dazhongjiu intelligent manufacturing tobacco stem pneumatic conveying flexible equipment, the completed equipment needs to be transported to the designated working position by the corresponding handling equipment.

[0073] When in use, the staff first place the equipment in a suitable place and connect the external negative pressure device to the negative pressure air duct (2). The tobacco stem box is moved to the vicinity of the equipment and opened by the external forklift equipment. Then, the tobacco stems are weighed and fed by the weighing and feeding device (1). The negative pressure dust removal device (5) will extract the dust generated during the weighing and feeding process. The weighed tobacco stems will be transported to the conveying device (3).

[0074] The staff starts the drive motor (823), which drives the connecting shaft (822), hollow shaft (811), material equalization roller (812) and first lever (815) to rotate. The first lever (815) moves and flattens the tobacco stems that have entered the surface of the conveying device (3), so that the tobacco stems move and are evenly distributed on the surface of the conveying device (3).

[0075] At the same time, the connecting shaft (822) will drive the cam (841) to rotate. During the rotation, the cam (841) will continuously squeeze the vertical plate (842), thereby driving the airbag (843) and the second spring (845) connected to the vertical plate (842) to squeeze. The gas inside the airbag (843) is transported to the rotating sleeve (846) through the air outlet pipe (844). Then, through the rotating sleeve (846), it passes through the connecting shaft through hole, connecting shaft (822), hollow shaft (811), first through hole (816), and equalizing roller cavity in sequence to the inner cavity of the sliding frame (814). It is then sprayed out from the air outlet (817) of the first lever (815) through the inner cavity of the first lever (815) and comes into contact with the tobacco stem, so that the first lever (815) dries the tobacco stem while it is being turned.

[0076] At the same time, during the rotation of the cam (841), it will squeeze the mounting plate (96), thereby driving the third spring (97) and the fixing block (95) connected to the mounting plate (96) to move. As a result, the fixing block (95) drives the second push block (94) connected to it to move. Then, the second push block (94) moves towards the first push block (93), and causes the first push block (93) to drive the sliding plate (92), the slider (99) and the second lever (910) to move laterally, so as to move and flatten the tobacco stem again, and complete the tobacco stem conveying work.

[0077] The beneficial effects of this invention compared to the prior art are:

[0078] 1. This invention is safe, reliable, adaptable, flexible, efficient, stable, reliable, and highly automated. It can greatly improve the automation level of the production line, reduce operating costs, improve production efficiency and product quality, and contribute to environmental protection and resource conservation. At the same time, by introducing the inflatable component (84), a more efficient and environmentally friendly production method is achieved, which also enhances the overall production competitiveness.

[0079] 2. The adjustment mechanism (7) provided in this invention can simultaneously adjust the height of the longitudinal feeding component (8) and the transverse feeding component (9) to adjust the height between the first lever (815) and the second lever (910) and the conveyor belt of the conveying device (3), thereby adjusting the thickness of the tobacco stems on the surface of the conveying device (3).

[0080] 3. The longitudinal feeding component (8) provided in this invention can drive the material distribution roller component (81) to rotate through the drive motor (823), thereby longitudinally feeding and flattening the tobacco stems on the conveying device (3), making the tobacco stems more evenly distributed and reducing the clumping phenomenon caused by some areas of the tobacco stems being too dense or piled up.

[0081] 4. The inflatable component (84) provided in this invention can spray gas from the air bag (843) through the air outlet (817) of the first lever (815) and contact the tobacco stem, so that the first lever (815) can dry the tobacco stem while moving it, preventing the tobacco stem from clumping due to humidity, thereby reducing the clumping of the tobacco stem during the transportation process and further improving the transportation effect of the equipment.

[0082] 5. The transverse feeding component (9) provided in this invention enables the tobacco stems to move in the transverse position of the conveying device (3), further ensuring the uniformity of tobacco stem distribution, thereby further improving the conveying efficiency and conveying stability of the equipment during use.

[0083] 6. The transverse feeding component (9) of the present invention is also provided with a spreading plate, which can control the overall thickness of the final tobacco stem to prevent it from being too thick and affecting the negative pressure conveying operation of the conveying device (3).

[0084] 7. The negative pressure dust removal device (5) provided in this invention can remove the dust and impurities generated during the transportation of tobacco stems in a timely manner through negative pressure suction, preventing them from being dispersed into the air during transportation. This not only keeps the production environment clean but also reduces the risk of equipment wear and blockage.

[0085] 8. The negative pressure duct (2) set in this invention can effectively control the tobacco stems from clumping due to moisture or other factors during the conveying process by maintaining a certain negative pressure environment. At the same time, negative pressure helps to maintain the fluidity of the material, avoid the accumulation or blockage of tobacco stems in the duct, and ensure the smooth operation of the equipment.

[0086] 9. The present invention is equipped with an adjustment component (83), which on the one hand can support and reinforce the material distribution roller assembly (81) and ensure the stability of the material distribution roller assembly (81) during rotation; on the other hand, it can also crush some debris or particles that enter the hollow shaft (811), effectively avoid accumulation problems, ensure the smooth flow of the hollow shaft, prevent material blockage or equipment damage, avoid production interruption and equipment failure that may be caused by material accumulation, and ensure long-term stable operation of the equipment.

[0116] To make the technical means, inventive features, objectives, and effects of this invention readily understandable, the technical solution of this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0117] Example 1

[0118] like Figures 1 to 19As shown, an improved flexible equipment for the pneumatic conveying process of tobacco stems in the intelligent manufacturing of Yunyan Dazhongjiu cigarettes includes a conveying device 3, a weighing and feeding device 1 installed at the inlet end of the conveying device 3, and a tobacco stem lifting device 4 installed at the outlet end of the conveying device 3. It also includes:

[0119] Mounting box 6 is positioned above the inlet end of conveying device 3;

[0120] Adjustment mechanism 7 is located in the upper part of the mounting box 6;

[0121] The longitudinal material feeding assembly 8 is slidably connected to the lower front side of the mounting box 6, and both ends of the longitudinal material feeding assembly 8 are connected to the adjustment mechanism 7.

[0122] The transverse feeding assembly 9 has one end connected to the longitudinal feeding assembly 8 via a transmission, and the other two ends of the transverse feeding assembly 9 are connected to the lower rear side of the adjustment mechanism 7.

[0123] The adjusting mechanism 7 is used to simultaneously adjust the working height between the longitudinal feeding assembly 8 and the transverse feeding assembly 9 and the conveying device 3; the longitudinal feeding assembly 8 is provided with an air-filling assembly 84, which is used to spray gas to contact the tobacco stems for flexible air drying.

[0124] When using the above embodiment 1, the staff first places the equipment in a suitable place and connects the external negative pressure device to the negative pressure air duct 2. The tobacco stem box is moved to the vicinity of the equipment and opened by the external forklift equipment. Then, the tobacco stems are weighed and fed by the weighing and feeding device 1. The negative pressure dust removal device 5 will extract the dust generated during the weighing and feeding process. The weighed tobacco stems will be transported to the conveying device 3.

[0125] The staff starts the drive motor 823, which drives the connecting shaft 822, hollow shaft 811, material equalization roller 812 and first lever 815 to rotate. The first lever 815 moves and flattens the tobacco stems that have entered the surface of the conveying device 3, so that the tobacco stems move and are evenly distributed on the surface of the conveying device 3.

[0126] Simultaneously, the connecting shaft 822 drives the cam 841 to rotate. During the rotation, the cam 841 continuously squeezes the vertical plate 842, which in turn squeezes the airbag 843 and the second spring 845 connected to the vertical plate 842. The gas inside the airbag 843 is transported to the rotating sleeve 846 through the air outlet pipe 844. Then, through the rotating sleeve 846, the gas passes through the connecting shaft through hole, the connecting shaft 822, the hollow shaft 811, the first through hole 816, and the material equalizing roller cavity before being transported to the inner cavity of the sliding frame 814. The gas is then sprayed out from the air outlet 817 of the first lever 815 through the inner cavity of the first lever 815 and comes into contact with the tobacco stem, so that the first lever 815 dries the tobacco stem while it is being turned.

[0127] At the same time, during the rotation of the cam 841, it will squeeze the mounting plate 96, thereby driving the third spring 97 and the fixing block 95 connected to the mounting plate 96 to move. As a result, the fixing block 95 drives the second push block 94 connected to it to move. Then, the second push block 94 moves towards the first push block 93, and the first push block 93 drives the sliding plate 92, the slider 99 and the second lever 910 to move laterally, thereby stirring and flattening the tobacco stem again.

[0128] In the above-described use, the operator can manually rotate the first hand crank 74 to drive the rotating shaft 71 and the first adjusting rod 72 to rotate. Utilizing the linkage effect between the first adjusting rod 72 and the first threaded sleeve 73, power is transmitted to the first threaded sleeve 73, causing the first threaded sleeve 73 to drive the sliding frame 75 and the connecting block 76 to move upward or downward. This, in turn, drives the longitudinal feeding assembly 8 and the transverse feeding assembly 9 connected to the connecting block 76 to move. Finally, the working height between the first lever 815 and the second lever 910 and the conveyor belt of the conveying device 3 is adjusted to adjust the thickness of the tobacco stems on the surface of the conveying device 3. It is convenient to use.

[0129] Example 2

[0132] The installation box 6 has a door-shaped structure, and the bottom two side plates of the installation box 6 have through-holes for connection.

[0133] In the above embodiment 2, due to the presence of the negative pressure dust removal device 5, the dust and impurities generated during the transportation of tobacco stems can be promptly removed by the negative pressure suction, preventing them from being dispersed into the air during transportation. This not only maintains the cleanliness of the production environment but also reduces the risk of equipment wear and blockage. Other uses are the same as in embodiment 1 and will not be repeated here.

[0134] Example 3

[0143] The working principle of the adjustment mechanism 7 in this embodiment 3 is as follows: the operator manually rotates the first hand crank 74, which in turn drives the rotating shaft 71 and the first adjusting rod 72 to rotate. As a result, the first adjusting rod 72 drives the first threaded sleeve 73 to move up or down. The first threaded sleeve 73 drives the sliding frame 75 to move. In turn, the sliding frame 75 drives the connecting block 76 connected to it to move up or down. This in turn drives the longitudinal feeding assembly 8 and the transverse feeding assembly 9 connected to the connecting block 76 to move. Finally, the height between the first lever 815 and the second lever 910 and the conveyor belt of the conveying device 3 is adjusted, thereby adjusting the thickness of the tobacco stems on the surface of the conveying device 3.

[0144] Example 4

[0145] This embodiment 4 is the same as the other embodiments, except that, as Figures 8 to 18 As shown, the longitudinal feeding assembly 8 includes: a material distribution roller assembly 81 and a drive connection assembly 82;

[0146] The material distribution roller assembly 81 includes: a hollow shaft 811, which is rotatably connected below between two connecting blocks 76;

[0147] The material leveling roller 812 is fixedly connected to the outer periphery of the hollow shaft 811, and the material leveling roller 812 has a material leveling roller cavity inside.

[0148] The first spring 813 is arranged in the cavity of the material equalizing roller, and one end of the first spring 813 is fixedly connected to the inner wall of the material equalizing roller 812.

[0149] Sliding frame 814 is fixedly connected to the other end of the first spring 813;

[0150] First lever 815, multiple first levers 815 are fixedly connected to the other side of sliding frame 814;

[0151] The sliding frame 814 and the first lever 815 are both slidably sealed within the material equalization roller 812.

[0153] The connecting box 821 is located in the connecting port on one side of the mounting box 6, and the connecting box 821 is fixedly connected to the outer wall of the connecting block 76 on that side.

[0154] The connecting shaft 822 is rotatably connected inside the connecting box 821, and one end of the connecting shaft 822 passes through the connecting box 821 and is fixedly connected to the outer wall of the hollow shaft 811;

[0155] The drive motor 823 is connected to the outer wall of the connecting box 821 via a support base, and the output shaft of the drive motor 823 is connected to the other end of the connecting shaft 822.

[0156] The fixing box 824 is located in the connection port on the other side of the mounting box 6, and the fixing box 824 is fixedly connected to the outer wall of the connecting block 76 on that side.

[0157] The working principle of the equalizing roller assembly 81 and the drive connection assembly 82 in the above embodiment 4 is as follows: The weighed tobacco stems are conveyed to the conveying device 3. At the same time, the drive motor 823 is started, and the output shaft of the drive motor 823 drives the connecting shaft 822 to rotate. In turn, the connecting shaft 822 drives the hollow shaft 811 connected to it to rotate. In turn, the hollow shaft 811 drives the equalizing roller 812 fixedly connected to it to rotate. Thus, the equalizing roller 812 drives the first lever 815 inside to rotate. Finally, the first lever 815 moves and flattens the tobacco stems that have entered the surface of the conveying device 3, so that the tobacco stems move and are evenly distributed on the surface of the conveying device 3, preventing them from clumping and accumulating on the conveying device 3, which would affect the negative pressure conveying effect of the equipment.

[0158] Example 5

[0159] Furthermore, such as Figure 11 and Figure 14 As shown, it also includes an adjustment assembly 83 disposed on the fixed housing 824.

[0160] Adjustment component 83 includes:

[0161] The second adjusting rod 831 is rotatably connected inside the fixed box 824, and one end of the second adjusting rod 831 extends to the outside of the fixed box 824.

[0162] The second hand crank 832 is fixedly connected to the second adjusting rod 831 on the outside.

[0163] The second threaded sleeve 833 is threadedly connected to the second adjusting rod 831;

[0164] A tapered cylinder 834 is fixedly connected to one side of the second threaded sleeve 837, and the tapered cylinder 834 is located on the side away from the second hand crank 832.

[0165] One end of the conical cylinder 834 passes through the end wall of the hollow shaft 811 and is located inside the hollow shaft 811. The end of the conical cylinder 834 away from the second threaded sleeve 833 is provided with four rollers 835 arranged in an equal-angle circular array. The other end of the rollers 835 is fixedly connected to a connecting rod 836. The other end of the connecting rod 836 passes through the inner wall of the hollow shaft 811 and the material equalizing roller 812 in sequence and is fixedly connected to the sliding frame 814.

[0166] In this invention, the second adjusting rod 831 is a lead screw or a threaded rod.

[0167] The working principle of the adjustment component 83 in the above embodiment 5 is as follows: When the debris or particles entering the hollow shaft 811 accumulate, the operator first stops the transport of tobacco stems on the conveying device 3. Then, the operator holds the second hand crank 832 and rotates the second hand crank 832 to drive the second adjustment rod 831 to rotate. Then, the second adjustment rod 831 gradually tightens against the second threaded sleeve 833. The second threaded sleeve 833 drives the conical cylinder 834 to rotate. With the continuous rotation of the second hand crank 832, the conical cylinder 834 continuously crushes and pulverizes the debris or particles. At the same time, the operator starts the drive motor 823. Driven by the drive motor 823, the gas in the air filling component 84 will spray the crushed debris or particles out from the air outlet 817 of the first lever 815, completing the removal of debris or particles from the hollow shaft 811. Meanwhile, during the operation of the material distribution roller assembly 81, the drive connection assembly 82, and the air filling assembly 84, they will also cooperate with the conical cylinder 834 to complete the crushing and removal of some of the debris or particles inside the hollow shaft 811, effectively preventing the accumulation of debris or particles inside the hollow shaft 811 and ensuring the stability of equipment operation.

[0168] Example 6

[0169] This embodiment 6 is as follows Figures 15 to 17 As shown, it also includes an inflation assembly 84 disposed on one side of the connecting shaft 822;

[0170] Inflatable assembly 84 includes:

[0171] Cam 841 is fixedly connected to connecting shaft 822;

[0172] Vertical plate 842 is slidably connected inside the connecting box 821, and vertical plate 842 is located on the outside side of cam 841;

[0173] Airbag 843, one end of airbag 843 is fixedly connected to vertical plate 842 on the side away from cam 841, and the other end of airbag 843 is fixedly connected to the inner wall of connecting box 821.

[0174] The air intake pipe is connected to one side of the airbag 843;

[0175] Air outlet pipe 844, one end of which is connected to the other side of airbag 843;

[0176] The second spring 845 is located at the four corners of the vertical plate 842, and the two ends of the second spring 845 are fixedly connected to the vertical plate 842 and the inner wall of the connecting box 821, respectively.

[0177] Rotary sleeve 846 is connected to the other end of air outlet pipe 844. One end of rotating sleeve 846 is fixedly connected to the inner wall of connecting box 821, and the other end of rotating sleeve 846 is rotatably sleeved on the outer periphery of connecting shaft 822.

[0178] One-way valves are installed on both the exhaust pipe 844 and the intake pipe.

[0179] Furthermore, such as Figures 13 to 17 The connecting shaft 822 is a cylindrical component with one open end and hollow inside. The connection end with the drive motor 823 is closed. Multiple connecting shaft through holes are also provided on the connecting shaft 822 which is sleeved in the rotating sleeve 846. The connecting shaft through holes are connected to the rotating sleeve and the air outlet pipe 814.

[0180] The open end of the connecting shaft 822 is connected to the hollow shaft 811. The hollow shaft 811 is connected to the material equalizing roller 812 and a first through hole 816 is also provided. The first through hole 816 is arranged in an equal angle circumferential array.

[0181] The sliding frame 814 has an inner cavity and an opening that communicates with the cavity of the equalizing roller. The first lever 815 is a tubular structure with one open end and a hollow interior. The non-connecting end of the first lever 815 has multiple air vents 817. The open end of the first lever 815 is connected to the sliding frame 814.

[0182] In this invention, the hollow shaft 811 and the material equalizing roller 812 are connected at an equal angle and have four first through holes 816 arranged in a circular array.

[0183] The working principle of the inflation component 84 in this embodiment 6 is as follows: During the rotation of the cam 841, it continuously compresses the vertical plate 842, thereby driving the airbag 843 and the second spring 845 connected to the vertical plate 842 to compress, so that the gas in the airbag 843 enters the rotating sleeve 846 through the air outlet pipe 844. Then, the gas enters the connecting shaft 822 from the rotating sleeve 846 through the connecting shaft through hole. Subsequently, the gas enters the hollow shaft 811 from the connecting shaft 822, and then the gas exits from the hollow shaft 811. 1. Gas enters the material distribution roller cavity of the material distribution roller 812 through the first through hole 816. Then, gas enters the inner cavity of the sliding frame 814 through the opening, and then enters the first lever 815. Finally, the gas is ejected from the air outlet 817 of the first lever 815 and comes into contact with the tobacco stem. This allows the first lever 815 to dry the tobacco stem while it is being moved, preventing the tobacco stem from clumping due to humidity. This reduces the clumping of the tobacco stem during the conveying process and further improves the conveying efficiency of the equipment.

[0184] In this invention, during the operation of the equalizing roller assembly 81, the drive connection assembly 82, and the air filling assembly 84, they also cooperate with the conical cylinder 834 to complete the crushing and removal of some of the debris or particles inside the hollow shaft 811, further extending the accumulation time of debris or particles inside the hollow shaft 811 and ensuring the stability of equipment operation.

[0185] When debris or particles accumulate inside the hollow shaft 811, the operator first stops the transport of tobacco stems on the conveying device 3. Then, the operator holds the second hand crank 832 and rotates it to drive the second adjusting rod 831 to rotate. As a result, the second adjusting rod 831 gradually tightens against the second threaded sleeve 833, which in turn drives the conical cylinder 834 to rotate. With the continuous rotation of the second hand crank 832, the conical cylinder 834 continuously crushes and pulverizes the debris or particles. At the same time, the operator starts the drive motor 823. Driven by the drive motor 823, the gas in the inflation component 84 will spray the crushed debris or particles out of the air outlet 817 of the first lever 815, thus completing the removal of debris or particles from the hollow shaft 811.

[0186] Example 7

[0187] Example 7 is as follows Figure 19 As shown, the transverse feeding assembly 9 includes:

[0188] Rectangular box 91, with its two sides connected to connecting block 76 respectively;

[0189] Slider 99 is slidably connected inside rectangular box 91;

[0190] Second lever 910, multiple second levers 910 pass through rectangular box 91 and are respectively connected to the bottom of slider 99;

[0191] The sliding plate 92 has one end passing through the rectangular box 91 and fixedly connected to the slider 99, and the sliding plate 92 is slidably connected inside the rectangular box 91.

[0192] The first push block 93 is fixedly connected to the other end of the sliding plate 92;

[0193] The fourth spring 98 is located on both sides of the first push block 93, and the two ends of the fourth spring 98 are fixedly connected to the first push block 93 and the inner wall of the connecting box 821, respectively.

[0194] The second push block 94 is located on one side of the first push block 93;

[0195] A fixing block 95, one end of which is connected to a second push block 94 on the side away from the first push block 93;

[0196] Mounting plate 96 is connected to the other end of fixing block 95. Mounting plate 96 is located on the other side of cam 841 and is in contact with cam 811.

[0197] The third spring 97 is respectively set on both sides of the fixing block 95, and the two ends of the third spring 97 are fixedly connected to the mounting plate 96 and the inner wall of the connecting box 821 respectively.

[0198] Specifically, such as Figure 4 and Figure 5 as well as Figure 19 As shown, the first push block 93 and the second push block 94 are generally in the shape of a cone or a triangular block. The inclined end face of the second push block 94 is in contact with the inclined end face of the first push block 93. The second push block 94 is larger than the first push block 93.

[0199] The mounting plate 96 is slidably connected inside the connecting box 821;

[0200] Among them, a spreading plate is also provided on the rectangular box 91 on the side away from the material distribution roller 812.

[0201] The working principle of the transverse feeding assembly 9 in this embodiment 9 is as follows: When the drive motor 823 starts, the output shaft of the drive motor 823 rotates, which in turn drives the cam 841 on the connecting shaft 822 to rotate. During the rotation, the cam 841 intermittently squeezes the mounting plate 96, which in turn drives the third spring 97 and the fixing block 95 connected to the mounting plate 96 to move. As a result, the fixing block 95 drives the second push block 94 connected to it to move, so that the second push block 94 moves towards the first push block 93, and the first push block 93 drives the sliding plate 92, the slider 99 and the second lever 910 to move laterally, which again moves and flattens the tobacco stems, so that the tobacco stems move in the transverse position of the conveying device 3, which further ensures the uniformity of the distribution of tobacco stems, thereby further improving the conveying efficiency and conveying stability of the equipment during use. The spreading plate will control the overall thickness of the final tobacco stems to prevent the thickness from being too thick, which would affect the negative pressure conveying operation of the device.

[0202] Furthermore, the transverse feeding component 9 ensures the uniform distribution of tobacco stems and improves the conveying efficiency and stability of the equipment during use. Since a spreading plate is also provided on the rectangular box 91, the spreading plate controls the overall thickness of the final tobacco stems to prevent them from being too thick and affecting the negative pressure conveying operation of the device.

[0203] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
