Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing, in particular to a tobacco sheet loosening control system. Background Art

[0002] Currently, the tobacco industry generally pressurizes and packs tobacco flakes into rectangular blocks of about 150 kg when manufacturing them, and then packs them into boxes and transports them to the silk-making production line; the silk-making production line unpacks and loosens the tobacco flakes according to the batch formula requirements, and then mixes them into tobacco leaves for use in silk-making together with the tobacco leaves.

[0003] Currently, in the actual use of tobacco flake loosening machines, tobacco flake bales that need to be loosened often have compacted cores due to factors such as prolonged storage and improper control of the packing pressure during manufacturing. Commonly used loosening machines are ineffective at loosening these bales. The flake bales constantly tumble in the loosening units, gradually forming lumps and failing to be effectively loosened, ultimately requiring manual intervention. This manual intervention involves first shutting down the loosening equipment and then manually removing any flakes from the outside of the loosening machine's silo using tools such as iron rods. After manual tearing and disassembly, the bales are returned to the production line for continued use. This manual intervention not only affects production efficiency but also poses a quality risk of tobacco flakes not being blended in a timely manner. Furthermore, manual intervention operations also carry certain safety risks. Summary of the Invention

[0014] The fixing rod extends along the third direction, and the photoelectric detection switch is provided on the fixing rod; along the first direction, the fixing rod is located between two adjacent feeding rollers;

[0015] The control module is also electrically connected to the detection photoelectric switch and is used to control the working states of the first cylinder and the second cylinder according to the detection signal of the photoelectric detection switch.

[0016] Optionally, in the first loosening mode, an angle θ1 between a line connecting the first loosening roller and the second loosening roller and the first direction satisfies 50°<θ1<90°;

[0017] In the second loosening mode, an angle θ2 between a line connecting the first loosening roller and the second loosening roller and the first direction satisfies 20°<θ2<50°;

[0018] Wherein, the volume of the tobacco sheets in the first loose mode is greater than the volume of the tobacco sheets in the second loose mode.

[0019] Optionally, the tobacco sheet loosening control system further comprises a driving module; the control module is further electrically connected to the driving module;

[0020] In the first loosening mode, the control module controls the driving module to drive the loosening roller to rotate in the clockwise direction;

[0021] In the second loosening mode, the control module controls the driving module to drive the loosening roller to rotate in the counterclockwise direction for a preset time and then rotate in the clockwise direction.

[0042] Figure 1 This is a schematic diagram of the structure of a tobacco sheet loosening control system provided by an embodiment of the present invention. Figure 2 This is a schematic diagram of the electrical connection of a control module in a tobacco sheet loosening control system provided by an embodiment of the present invention, as shown in FIG. Figure 1 and Figure 2 As shown, the tobacco sheet loosening control system includes a plurality of feed rollers 10, at least two loosening rollers 20, at least two cylinders 30, a control module 40 and a detection module 50; the plurality of feed rollers 10 are arranged along a first direction (the X direction shown in the figure) and all extend along a second direction (the Y direction shown in the figure); the first direction X intersects with the second direction Y; the plurality of feed rollers 10 all rotate in a counterclockwise direction for conveying tobacco sheets 60; along a third direction (the Z direction shown in the figure), at least two loosening rollers 20 are located on the same side of the feed roller 10, and the at least two loosening rollers 20 include a first loosening roller 201 and a second loosening roller 202; the first loosening roller 201 and the second loosening roller 202 are arranged along the third direction Z, the first loosening roller 201 is located on the side of the second loosening roller 202 away from the feed roller, and both rotate along the second direction Y extends, and the third direction Z intersects with the first direction X and the second direction Y; the loosening roller 20 is used to loosen the tobacco sheet 60; the at least two cylinders 30 include a first cylinder 301 and a second cylinder 302; the first cylinder 301 is connected to the first loosening roller 201, and the second cylinder 302 is connected to the second loosening roller 202; the detection module 50 is electrically connected to the control module 40, and is used to detect volume information of the tobacco sheet 60 and send the volume information to the control module 40; the control module 40 is electrically connected to the first cylinder 301 and the second cylinder 302, respectively, and is used to control the first cylinder 301 to push the first loosening roller 201 to move a first preset distance along the first direction X and the second cylinder 302 to push the second loosening roller 202 to move a second preset distance along the first direction X according to the volume information; the first preset distance is greater than the second preset distance.

[0043] Specifically, tobacco flakes 60, also known as reconstituted tobacco leaves or homogenized tobacco leaves, are made from waste tobacco leaf fragments, tobacco dust, tobacco stems or low-grade tobacco leaves in the cigarette production process, which are processed, and adhesives and other additives are added. After drying and other process treatments, they are prepared into sheet products with properties close to or better than natural tobacco leaves. The production of tobacco flakes 60 can make full use of tobacco waste, effectively improve the utilization rate of tobacco materials, and thus reduce the production cost of cigarettes. In addition, tobacco flakes 60 can also effectively reduce the harmful components such as nicotine and tar brought by cigarettes, while retaining the original taste of cigarettes, and achieve effective tar reduction without affecting the quality of cigarettes, becoming a more useful way to reduce tar and reduce harm in current cigarettes. At present, in China, tobacco flakes 60 are cut into shreds and filled into shredded tobacco.

[0044] Specifically, multiple feed rollers 10 are arranged along a first direction X and extend along a second direction Y. Multiple feed rollers 10 rotate in a counterclockwise direction. In this way, the tobacco sheets 60 on the feed rollers 10 can be transferred to the loosening roller 20 to the left for loosening under the rotation of the multiple feed rollers 10. That is, the feed rollers 10 continuously bring the tobacco sheets 60 into contact with the loosening roller 20, and the rake nails on the loosening roller 20 rotate backward to break up the tobacco sheets 60 to form a small volume of tobacco sheets 60. Such a small volume of tobacco sheets 60 can fall from the gap between two adjacent feed rollers 10 into the feeder hopper below for subsequent blending and other operations.

[0045] Specifically, along the third direction Z, at least two loosening rollers 20 are located above the feed roller 10, and the at least two loosening rollers 20 include a first loosening roller 201 and a second loosening roller 202. The first loosening roller 201 and the second loosening roller 202 are arranged along the third direction Z, with the first loosening roller 201 located on the side of the second loosening roller 202 away from the feed roller, that is, the first loosening roller 201 is located above the second loosening roller. A first cylinder 301 is connected to the first loosening roller 201 so that the first cylinder 301 pushes the first loosening roller 201 to move along the first direction X. The second cylinder 302 is connected to the second loosening roller 202 so that the second cylinder 302 pushes the second loosening roller 202 to move along the first direction X. In other words, the first cylinder 301 can push the first loosening roller 201 to the right, and the second cylinder 302 can push the second loosening roller 202 to the right.

[0046] Specifically, the detection module 50 is configured to detect the volume of the tobacco sheet 60 and transmit the volume information to the control module 40. The control module 40 then determines the volume of the tobacco sheet based on the volume information and controls the movement distance of the loosening roller by the cylinder based on the volume information. For example, the detection module 50 may be an image detection module.

[0047] Furthermore, the control module 40 is electrically connected to the first cylinder 301 and the second cylinder 302 respectively, and is used to control the first cylinder 301 to push the first loosening roller 201 to move a first preset distance along the first direction X and the second cylinder 302 to push the second loosening roller 202 to move a second preset distance along the first direction X according to the volume information of the tobacco sheet 60. Specifically, when the tobacco sheets 60 are just placed in the tobacco sheet loosening control system, due to the large volume of the tobacco sheets 60, the control module 40 controls the first cylinder 301 to push the first loosening roller 201 to move a first preset distance along the first direction X and the second cylinder 302 to push the second loosening roller 202 to move a second preset distance along the first direction X, which can be relatively small, and the first preset distance is greater than the second preset distance. In this way, it can be ensured that the center of gravity of the first loosening roller 301 and the center of gravity of the second loosening roller 302 are staggered, and then the angle formed by the line between the first loosening roller 301 and the second loosening roller 302 and the first direction X is less than 90°. In this way, the clamping force and loosening torque of the loosening roller 20 on the agglomerated cigarette pack can be increased, and the loosening and stirring of the cigarette block by the loosening roller can be increased to loosen the large volume of tobacco sheets 60.

[0048] During the loosening process, the volume of the tobacco sheet 60 gradually decreases. When the volume of the tobacco sheet 60 is small, the control module 40 controls the first cylinder 301 to push the first loosening roller 201 to move a first distance along the first direction X and the second cylinder 302 to push the second loosening roller 202 to move a second preset distance along the first direction X, which can be relatively large, and the first preset distance is greater than the second preset distance. In this way, it can be ensured that the center of gravity of the first loosening roller 301 and the center of gravity of the second loosening roller 302 are staggered, and then the angle formed by the line between the first loosening roller 301 and the second loosening roller 302 and the first direction X is further reduced. The smaller the volume of the tobacco sheet 60, the smaller the angle. In this way, the clamping force and loosening torque of the loosening roller 20 on the small-volume agglomerated cigarette packs can be further increased, and the loosening and stirring of the cigarette blocks by the loosening roller are increased to loosen the small-volume tobacco sheet 60.

[0049] Optional, continue to refer to Figure 1 The tobacco sheet loosening control system further includes a feeding belt 70 ; along the first direction X, the feeding belt 70 is located on a side of the feeding roller 10 away from the loosening roller 20 .

[0050] Specifically, tobacco sheet cigarette packs can be transported into the tobacco sheet loosening control system through the feeding belt 70, and the feeding belt 70 is located at the rightmost end of the feeding roller 10, so that the tobacco sheets on the feeding belt 70 leak into the feeding roller 10 and are then transmitted to the loosening roller 20 by the feeding roller 10.

[0051] In an embodiment of the present invention, a tobacco sheet loosening control system is provided. A control module is electrically connected to a first cylinder and a second cylinder, respectively, and is configured to control the first cylinder to move a first loosening roller in a first direction a first preset distance, and the second cylinder to move a second loosening roller in the first direction a second preset distance, based on the volume of the tobacco sheet. The first preset distance is greater than the second preset distance. In other words, the control module can adjust the distance the cylinders move the loosening rollers in the first direction based on the volume of the tobacco sheet, thereby increasing the force exerted by the loosening rollers on the tobacco sheet, further loosening the tobacco sheet, improving the loosening efficiency of the tobacco sheet, ensuring product quality, and avoiding manual intervention, thereby reducing safety hazards.

[0052] Optional, continue to refer to Figure 1 The angle between the connecting line between the first loosening roller 201 and the second loosening roller 202 and the first direction X is positively correlated with the volume of the tobacco sheet 60 .

[0053] Specifically, the angle between the line connecting the first loosening roller 201 and the second loosening roller 202 and the first direction X is determined by a first preset distance that the first cylinder 301 pushes the first loosening roller 201 to move along the first direction X and a second preset distance that the second cylinder 302 pushes the second loosening roller 202 to move along the first direction X. The greater the difference between the first preset distance and the second preset distance, the smaller the angle.

[0054] Specifically, the clamping force and loosening torque of the loosening roller 20 on the agglomerated cigarette pack are related to the size of the angle, that is, the greater the clamping force and loosening torque of the loosening roller 20 on the agglomerated cigarette pack, the smaller the angle; the smaller the clamping force and loosening torque of the loosening roller 20 on the agglomerated cigarette pack, the larger the angle. It should be noted that during the process of loosening the tobacco sheets, the angle is always less than 90° to ensure the loosening effect on the tobacco sheets. When the volume of the tobacco sheets 60 is large, the larger the angle, the larger the volume of tobacco sheets can be loosened without the loosening roller 20 applying a large clamping force and loosening torque to the agglomerated cigarette pack; when the volume of the tobacco sheets 60 is small, the smaller the angle, the more necessary it is to increase the clamping force and loosening torque of the loosening roller 20 on the agglomerated cigarette pack, increase the loosening and stirring of the tobacco blocks by the loosening roller, and further loosen the small volume of tobacco sheets 60, thereby improving the loosening effect.

[0055] Optional, continue to refer to Figure 1 and Figure 2The tobacco sheet loosening control system also includes a photoelectric detection switch 80 and a fixed rod 90; the photoelectric detection switch 80 is used to detect the tobacco sheet 60; the fixed rod 90 extends along the third direction Z, and the photoelectric detection switch 80 is set on the fixed rod 90; along the first direction X, the fixed rod 90 is located between two adjacent feeding rollers 10; the control module 40 is also electrically connected to the detection photoelectric switch 80, and is used to control the working status of the first cylinder 301 and the second cylinder 302 according to the detection signal of the photoelectric detection switch 80.

[0056] Specifically, the photoelectric detection switch 80 is mounted on the fixing rod 90 for securing. The photoelectric detection switch 80 is used to detect the presence of tobacco sheets 60. Specifically, when the photoelectric detection switch 80 detects that the tobacco sheets 60 have not been completely loosened, the photoelectric detection switch 80 is not conducting, and the loosening roller 20 and the feed roller 10 continue to move. The control module 40 controls the first cylinder 301 to move the first loosening roller 201 a first preset distance in the first direction X, and controls the second cylinder 302 to move the second loosening roller 202 a second preset distance in the first direction X, thereby loosening the tobacco sheets 60. When the photoelectric detection switch 80 detects that the tobacco sheets 60 have been completely loosened, that is, when the photoelectric detection switch 80 detects that there are no tobacco sheets 60, the control module 40 controls the first and second cylinders to reset, eliminating the need to move the loosening roller 20. This enables automated control of the system.

[0057] Optional, continue to refer to Figure 1 In the first loose mode, the angle θ1 between the line connecting the first loose roller 201 and the second loose roller 202 and the first direction satisfies 50°<θ1<90°; in the second loose mode, the angle θ2 between the line connecting the first loose roller 201 and the second loose roller 202 and the first direction satisfies 20°<θ2<50°; wherein, the volume of the tobacco sheet 60 in the first loose mode is greater than the volume of the tobacco sheet 60 in the second loose mode.

[0058] Specifically, the control module 40 can determine a loosening mode based on the acquired volume information and perform corresponding loosening operations corresponding to the loosening mode. The first loosening mode can be understood as a mode in which the volume of the tobacco sheet 60 is relatively large, while the second loosening mode can be understood as a mode in which the volume of the tobacco sheet 60 is relatively small. Furthermore, when the volume information of the tobacco sheet 60 detected by the detection module 50 is transmitted to the control module 40, the control module 60 can compare the acquired current volume information with a preset volume. If the current volume information is greater than the preset volume, the control module 60 determines that the tobacco sheet is in the first loosening mode; if the current volume information is less than or equal to the preset volume, the control module 60 determines that the tobacco sheet is in the second loosening mode.

[0059] For example, the preset volume may be half, one-third, or one-quarter of the volume of the tobacco sheet before it is loosened. The embodiment of the present invention does not specifically limit the preset volume.

[0060] Specifically, in the first loosening mode, the angle θ1 satisfies 50°<θ1<90°. Due to the large volume of the tobacco sheets 60, the large-volume tobacco sheets can be loosened without the need for the loosening rollers to apply a large clamping force and loosening torque to the agglomerated cigarette packs. In the second loosening mode, the angle θ2 satisfies 20°<θ2<50°. Due to the small volume of the tobacco sheets 60, it is necessary to increase the clamping force and loosening torque of the loosening rollers on the agglomerated cigarette packs, thereby increasing the loosening and stirring of the tobacco sheets by the loosening rollers to further loosen the small-volume tobacco sheets 60, thereby improving the loosening effect. Exemplarily, θ1=80°. Exemplarily, θ2=40°.

[0061] Optional, continue to refer to Figure 1 and Figure 2 The tobacco sheet loosening control system also includes a driving module 100; the control module 40 is also electrically connected to the driving module 100; in the first loosening mode, the control module 40 controls the driving module 100 to drive the loosening roller 20 to rotate in a clockwise direction; in the second loosening mode, the control module 40 controls the driving module 100 to drive the loosening roller 20 to rotate in a counterclockwise direction for a preset time and then rotate in a clockwise direction.

[0062] Specifically, in the first loosening mode, the control module 40 controls the driving module 100 to drive the loosening roller 20 to rotate in a clockwise direction. Due to the action force between the feeding roller 10 and the loosening roller 20, a large volume of tobacco sheets can be loosened.

[0063] Specifically, in the second loosening mode, the control module 40 is further configured to control the drive module 100 to drive the loosening roller 20 to rotate counterclockwise for a preset time, and then to rotate clockwise. In other words, in the second loosening mode, the loosening roller 20 can be controlled to reverse, that is, the loosening roller 20 first rotates counterclockwise. In this way, the agglomerated cigarette packs can be turned over by the loosening roller 20 and the feed roller 10. After changing the contact point with the loosening roller 20, the loosening roller 20 is reversed, that is, rotated clockwise again, to continue loosening the agglomerated cigarette packs. This can prevent agglomerated cigarette packs from getting stuck, making them easier to decompose.

[0064] It should be noted that the preset time can be understood as the time for the loose roller to rotate in the counterclockwise direction. For example, the preset time can be 1 second, etc. The embodiment of the present invention does not specifically limit the preset time.

[0065] Optional, continue to refer to Figure 1 and Figure 2The tobacco sheet loosening control system also includes a driving module 100; the driving module 100 includes a first driving module 101 and a second driving module 102; the first driving module 101 is electrically connected to the first loosening roller 201, and is used to drive the first loosening roller 201 to rotate; the second driving module 102 is electrically connected to the second loosening roller 202, and is used to drive the second loosening roller 202 to rotate; the control module 40 is also electrically connected to the first driving module 101 and the second driving module 102 respectively, and is used to control the first driving module 101 to output a first preset speed to the first loosening roller 201, and is also used to control the second driving module 102 to output a second preset speed to the second loosening roller 202; the first preset speed is different from the second preset speed.

[0066] Specifically, the control module 40 controls the first drive module 80 and the second drive module 102 to output different rotational speeds, so that the first loosening roller 201 and the second loosening roller 202 can rotate at different rotational speeds, and then the cigarette pack sheet 60 can withstand different forces at the same time to ensure the rapid decomposition and loosening of the agglomerated cigarette packs, which can further improve the loosening efficiency.

[0067] For further reference, Figure 1 and Figure 2 The first preset speed is greater than the second preset speed, that is, the control module 40 controls the first driving module 80 to output a speed greater than the speed of the second driving module 102 to output to the second loosening roller 202, that is, the rotation speed of the first loosening roller 201 is greater than the rotation speed of the second loosening roller 202, which is beneficial to ensure that the first loosening roller 201 exerts a greater force on the tobacco sheet 60, which can further improve the loosening efficiency.

[0068] Optional, continue to refer to Figure 1 The tobacco sheet loosening control system further includes an observation window 160 ; the feeding roller 10 , the loosening roller 20 , the cylinder 30 , the control module and the detection module are all located in the observation window 160 .

[0069] Specifically, by locating the feed roller 10, the loosening roller 20, the cylinder 30, the control module and the like in the observation window 160, the operator can timely understand the looseness of the tobacco sheets 60 through the observation window, and then control the amount of tobacco sheets 60 on the feed belt 70 according to the amount of remaining material in the observation window, thereby preventing problems such as material jamming.

[0070] Optional, continue to refer to Figure 1The tobacco sheet loosening control system also includes a feeder bottom belt 110, a feeder lifting belt 120 and a feeder hopper 130; the feeder bottom belt 110, the feeder lifting belt 120 and the observation window 160 are all located in the feeder hopper 130; along the third direction Z, the feeder bottom belt 110 is located on the side of the feed roller 10 away from the loosening roller 20; along the first direction X, the feeder lifting belt 120 is located on one side of the feed roller 10; the feeder bottom belt 110 is connected to the feeder lifting belt 120.

[0071] Specifically, the loosened small-volume tobacco sheets fall into the feeder bottom belt 110 through the gap between two adjacent feeding rollers 10. The feeder bottom belt 110 can transfer the material to the feeder lifting belt 120, and the feeder lifting belt 120 then transports the thin material to the next level equipment for blending.

[0072] Specifically, the feeder bottom belt 110, the feeder lifting belt 120 and the observation window 100 are all located in the feeder silo 130. This can prevent the tobacco sheets in the feeder silo 130 from being contaminated by the external environment on the one hand, and on the other hand, it can realize the integrated setting of the tobacco sheet loose control system.

[0073] Optional, continue to refer to Figure 1 The tobacco sheet loosening control system also includes a screed roller 140. When the tobacco sheets loosened by the screed roller are transported from bottom to top through the feeder lifting belt 120, the screed roller 140 can further loosen the tobacco sheets to ensure the uniformity of the material.

[0074] Optional, continue to refer to Figure 1 The tobacco sheet loosening control system also includes a material level photoelectric switch 150, which is located under the feeder bottom belt 110. If the material level photoelectric switch 150 installed under the feeder bottom belt is blocked by the material and triggered, it means that the sheet material layer on the bottom belt is too high. The control module controls the feed roller 10 to stop feeding, while the loosening roller 20 continues to rotate to loosen the thin sheet cigarette packs; at the same time, after the photoelectric switch for detecting the material level is triggered, the feeder bottom belt 110 conveys the loosened tobacco sheets forward until the material level photoelectric switch 150 is de-triggered. The tobacco sheet loosening control system completes the loosening action of a cigarette pack, and the upstream equipment can convey the next thin sheet cigarette pack to the loosening machine.

[0075] Optional, continue to refer to Figure 1 The tobacco sheet loosening control system further includes a bracket 160 for supporting the feeder silo 130 .

[0076] In summary, the tobacco sheet loosening control system provided by the embodiments of the present invention can improve the loosening effect of tobacco sheet cigarette packs, increase production efficiency, reduce the quality risk of sheet blending, and ensure product quality. Furthermore, the system is highly integrated and can achieve automatic control, reducing manual intervention, alleviating labor intensity, and mitigating safety hazards.
