[0002] In the process of making cigarettes, the picked tobacco leaves are first aged for several years to form tobacco blocks. The qualified tobacco blocks are cut into 4-5 pieces by a slicer according to the process requirements. The cut tobacco blocks are sent to the next process: vacuum rehumidification. In this process, the vacuum rehumidification machine seals the tobacco blocks in a closed space, draws vacuum, and sprays steam and water to make the tobacco leaves loose and uniform, increase the moisture content and temperature of the tobacco leaves, and increase the toughness of the tobacco leaves, thereby reducing the breakage of the tobacco leaves during the processing and reducing the loss of tobacco leaves.

Even after the tobacco blocks are cut, they still remain in block shape and are still dense. As a result, after the tobacco blocks are moistened in vacuum, some of the tobacco leaves are still not completely loose and are still in a clumping state. This affects subsequent transportation, easily causes blockage, and makes the temperature and humidity of the tobacco leaves uneven, affecting the stability of subsequent process indicators.

[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] In the description of the present application: the terms "first" and "second" are intended to distinguish the objects referred to, and the terms "including", "having" and any variations of them are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that have been explicitly listed, but may also include other steps or units that are not explicitly listed but are inherent to these processes, methods, products or devices, or steps or units added based on further optimization schemes conceived in the present application.

[0028] refer to Figure 1-3 The present application discloses a tobacco block pre-loosening device, which is located at the next station of the slicer and the previous station of the vacuum rehumidification machine. The tobacco block pre-loosening device includes two frames 1 and two conveying components 2 connected to the frames 1. The two conveying components 2 correspond to the two frames 1 one by one. The conveying component 2 includes a conveyor belt 21 for transmitting the cut small tobacco blocks 6 and a driving component 22 for driving the conveyor belt 21 to rotate. The two conveyor belts 21 are clearance-matched. Any one of the two frames 1 is connected to a first adjusting component 4 for driving the two conveyor belts 21 to move away from or close to each other.

[0029] The tobacco block pre-loosening device is located between the slicer and the vacuum rehumidification machine. The tobacco block is cut into multiple small blocks in the slicer. Multiple small tobacco blocks 6 are transmitted to the tobacco block pre-loosening device, and multiple small tobacco blocks 6 are located between two conveyor belts 21. The driving component 22 drives the conveyor belt 21 to rotate, and the conveyor belt 21 transports multiple small tobacco blocks 6 to the vacuum rehumidification machine. Among them, the first adjustment component 4 can drive the two conveyor belts 21 to move away from or close to each other. In this way, the gap distance between the two conveyor belts 21 can be adjusted according to the thickness and other dimensions of the small tobacco blocks 6, so that the two conveyor belts 21 can squeeze the small tobacco blocks 6, so that the small tobacco blocks 6 are squeezed in advance before entering the vacuum rehumidification machine, so that the whole small tobacco block 6 is squeezed and loosened to form a thinner slice. In this way, the slices entering the vacuum rehumidification machine are more easily loosened, effectively reducing the clumping of tobacco leaves.

[0030] The slicer and vacuum moisturizing machine are both existing technologies, and their specific structures are not shown in the figure, and their working principles are not described in detail.

[0031] During the processing of the tobacco block, the size of the entire tobacco block (before cutting) is 120*60*60cm. The slicer generally cuts the entire tobacco block into 4 pieces, each of which is 60*30*60cm in size. The cut parts are facing upward and arranged neatly. After entering the tobacco block pre-loosening device, the two conveyor belts 21 rotate in the same direction.

[0032] refer to Figure 1-4 The first adjustment assembly 4 includes a connecting piece 41 connected to the frame 1 and a first motor 42 connected to a support piece 45. The support piece 45 is connected to the ground. The output shaft of the motor is rotatably connected to a screw rod 43. The screw rod 43 is inserted through the connecting piece 41 and is threadedly engaged with the connecting piece 41. The first motor 42 drives the screw rod 43 to rotate. The screw rod 43 is threadedly engaged with the connecting piece 41. The rotation of the screw rod 43 can drive the connecting piece 41 and the frame 1 to move along the length extension direction of the screw rod 43. In this way, the distance between the two conveyor belts 21 can be adjusted so that the two conveyor belts 21 are close to squeeze the small cigarette blocks 6.

[0033] One end of the screw rod 43 away from the first motor 42 is rotatably connected to the support block 44, and the support block 44 is connected to the ground through a fastener 441. The screw rod 43 mainly supports the frame 1, and the support block 44 can be fixed to the ground through expansion bolts or the like.

[0034] The frame 1 includes two first support plates 11, the conveying assembly 2 includes a plurality of conveying rollers 222 rotatably connected between the two first support plates 11 and a second motor 221 for driving any one of the plurality of conveying rollers 222 to rotate, the conveyor belt 21 is wound around the plurality of conveying rollers 222, and the connecting member 41 is connected to the outer wall of any one of the two first support plates 11.

[0035] The spacing between the multiple conveying rollers 222 is reasonably arranged so that the conveyor belt 21 can be tightened. In particular, when the small cigarette block 6 is squeezed, the small cigarette block 6 gives a reaction force to the conveyor belt 21, causing the conveyor belt 21 to deform, and the tightened conveyor belt 21 can resist the reaction force, so that the small cigarette block 6 can be squeezed into thin sheets.

[0036] The outer side wall of the first support plate 11 away from the connecting member 41 is slidably connected with a support rod 23, one end of which is connected to the ground, and the support rod 23 is parallel to the screw rod 43. The support rod 23 supports the frame 1 on the other side so that the frame 1 will not fall over, and the support rod 23 and the first support plate 11 are slidably matched, and the working match between the first motor 42 and the screw rod 43 is not affected.

[0037] There are two support rods 23, and the two support rods 23 are arranged at intervals along the length direction of the first support plate 11. Since the support plate and the conveyor belt 21 are both relatively long in the length direction (longer than the dimensions in other directions), the two support rods 23 can support the first support plate 11 relatively stably.

[0038] In some embodiments, the outer side wall of the first support plate 11 close to the connecting member 41 may also be slidably connected to two support rods 23 , and the two support rods 23 are also arranged along the length direction of the first support plate 11 .

[0039] There are two first adjustment components 4, and the two first adjustment components 4 correspond to the two racks 1 one by one. The two first adjustment components 4 provide design redundancy on the one hand, to avoid failure of one of the first adjustment components 4, which makes the entire tobacco block pre-loosening device unusable; on the other hand, the two first adjustment components 4 work at the same time, the extrusion force of the conveyor belt 21 is greater, and the tobacco block dispersion effect is better; it should be further explained that the two first adjustment components 4 can be respectively arranged on both sides of the rack 1 to avoid interference in spatial position.

[0040] The frame 1 is also connected to a second adjustment component 5 for driving the inclination of the conveyor belt 21. The second adjustment component 5 includes two second support plates 51 and an inclination roller 55. The two second support plates 51 are located on the inner side of the two first support plates 11, and the two second support plates 51 correspond to the two first support plates 11 one by one. The two ends of the inclination roller 55 are respectively fixedly connected to the second support plates 51. The two ends of the inclination roller 55 pass through the second support plates 51, and the passing end is rotatably connected to the first support plate 11, wherein one end of the inclination roller 55 is rotatably connected to the connecting member 41, and the connecting member 41 is connected to a third motor 53 for driving the inclination roller 55 to rotate, and a plurality of conveyor rollers 222 are rotatably connected to the second support plate 51. In order to further improve the extrusion effect, the third motor 53 drives the inclination roller 55 to rotate, and the inclination roller 55 is fixedly connected to the second support plate 51. In this way, the two second support plates 51 drive the plurality of conveyor rollers 222 and the conveyor belt 21 to rotate together, so that the angle between the two conveyor belts 21 can be changed; generally, during operation, refer to the attached Figure 5 , rotate the angle between the two conveyor belts 21 to make the gap near one end of the vacuum rehumidifier smaller, so that the tobacco blocks are gradually squeezed during the squeezing process, which is conducive to the dispersion of the tobacco blocks.

[0041] The connecting member 41 is located in the middle of the first support plate 11 along its length, and the length extension direction of the angle roller 55 is perpendicular to the length extension direction of the first support plate 11. In this way, the weight of both sides of the angle roller 55 is similar, which is convenient for the third electromechanical drive.

[0042] The output shaft of the third motor 53 is connected to the first gear 54, and the outer peripheral wall of one end of the tilt roller 55 is connected to the second gear 551 for meshing with the first gear 54. The transmission relationship between the meshing gears is relatively stable.

[0043] In some embodiments, the first motor 42, the second motor 221 and the third motor 53 can all be electrically connected to the central controller, and the central controller controls the opening and closing and the rotation speed of the first motor 42, the second motor 221 and the third motor 53. Among them, the second motors 221 of the two racks 1 can be set differentially, that is, the rotation speeds of the two second motors 221 can be different. In this way, the tobacco block can be subjected to a certain friction during the transmission process, thereby further improving the looseness of the tobacco block.

[0044] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0045] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
