[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] In order to enable those in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] An embodiment of the present invention discloses a conveying device for reconstituted tobacco leaves. As shown in the attached Figure 1 figure, it includes a bracket 1, a conveyor belt 2, a tensioning wheel 3, and an adjusting assembly 4. At least one side of the bracket 1 is fixedly provided with a support plate 11, and the bracket 1 plays a supporting role. The bracket 1 is a frame structure. As a preferred embodiment, the bracket 1 includes an upper support frame 13, a lower support frame, support columns, and roller supports. The upper support frame 13 and the lower support frame are arranged up and down and are parallel to each other. Four support columns are integrally connected between the upper support frame 13 and the lower support frame. Each end of the upper support frame 13 is provided with a roller support, and each roller support is internally provided with a rotating roller. The conveyor belt 2 is wound between the two rotating rollers. Two opposite sides of the upper support frame 13 are each welded with a support plate 11, and the two support plates 11 are parallel to each other and are used to support the adjusting assembly 4.

[0048] As shown in the attached Figure 1 and 2As shown in the figure, the conveyor belt 2 is a steel belt. The conveyor belt 2 is wound around the bracket 1 and is used to convey reconstituted tobacco leaves. The conveyor belt 2 is perpendicular to the support plate 11, so that the moving direction of the adjusting assembly 4 is perpendicular to the conveyor belt 2. The tensioning wheel 3 is horizontally arranged across the conveyor belt 2. When tensioned, the tensioning wheel 3 abuts against the conveyor belt 2. As a preferred embodiment, the tensioning wheel 3 abuts against the lower belt 22 of the conveyor belt 2 to ensure that the tensioning wheel 3 does not affect the feeding of the upper belt 21 of the conveyor belt 2 during the tensioning process.

[0049] The adjusting assembly 4 is arranged on the support plate 11, and the support plate 11 provides support for the adjusting assembly 4. The adjusting assembly 4 is fixedly connected to the tensioning wheel 3, so that the adjusting assembly 4 drives the tensioning wheel 3 to move.

[0050] When the adjusting assembly 4 is started, the adjusting assembly 4 drives the tensioning wheel 3 to move along the support plate 11. Since the conveyor belt 2 is perpendicular to the support plate 11, the tensioning wheel 3 moves relative to the conveyor belt 2 in a direction perpendicular to the conveyor belt 2, so that the tensioning wheel 3 presses against or lifts off the conveyor belt 2 to adjust the tension of the conveyor belt 2, ensuring that the conveyor belt 2 always remains in a tensioned state, avoiding the conveyor belt 2 from slipping due to slack, shortening the fault time, and improving the production efficiency.

[0051] The adjusting assembly 4 includes a sliding seat 41 and a tensioning driving member 42. A slide rail 12 is fixedly arranged on the side of the support plate 11 facing the conveyor belt 2. The sliding seat 41 is slidably matched with the slide rail 12, so that the slide rail 12 guides the sliding seat 41 to slide up and down. The wheel support of the tensioning wheel 3 is fixedly arranged at the bottom of the sliding seat 41, and the tensioning wheel 3 is rotatably installed on the wheel support, so that the sliding seat 41 drives the tensioning wheel 3 to move up and down synchronously. The tensioning driving member 42 is fixedly connected to the sliding seat 41 and is fixedly arranged on the support plate 11. The tensioning driving member 42 is used to drive the sliding seat 41 to slide along the slide rail 12. The tensioning driving member 42 can specifically be a tensioning cylinder or a linear motor, and no specific embodiment is given here.

[0052] As shown in the attached Figure 2 As shown in the figure, the sliding seat 41 is a U-shaped seat. The sliding seat 41 includes two sliders 411 and a moving plate 412. The two sliders 411 are arranged oppositely, and the two sliders 411 are respectively slidably matched with the slide rails 12 arranged on the two support plates 11 to ensure that both sides of the sliding seat 41 are evenly stressed and avoid jamming of the adjusting assembly 4 due to uneven stress. The moving plate 412 is integrally and vertically connected between the two sliders 411. The wheel support is fixedly arranged at the bottom of the moving plate 412, so that the moving plate 412 drives the tensioning wheel 3 to move up and down synchronously through the wheel support when the two sliders 411 slide. Of course, the structure of the sliding seat 41 is not limited to this.

[0053] The conveying device for reconstituted tobacco leaves further includes a distance detector 5 and a controller 6. The distance detector 5 is fixedly arranged on the sliding seat 41. The distance detector 5 is used to detect the actual distance between the sliding seat 41 and the conveyor belt 2. The distance detector 5 can specifically be a laser rangefinder, but is not limited thereto. The controller 6 is respectively connected to the distance detector 5 and the tensioning driving member 42. The controller 6 is specifically fixedly arranged on one side of the bracket 1.

[0054] When the actual distance detected by the distance detector 5 between the sliding seat 41 and the conveyor belt 2 is inconsistent with the set distance, the distance detector 5 feeds back a signal to the controller 6. After receiving the signal, the controller 6 makes a judgment and processing, and sends the generated signal to the tensioning driving member 42 to automatically start the tensioning driving member 42, so that the tensioning driving member 42 automatically adjusts the position of the tensioning wheel 3, thereby realizing the automatic adjustment of the tensioning force with a relatively high adjustment accuracy.

[0055] As a preferred embodiment, when the actual distance detected by the distance detector 5 between the sliding seat 41 and the conveyor belt 2 is greater than the set distance, the controller 6 controls the tensioning driving member 42 to drive the tensioning wheel 3 to move upward according to the signal fed back by the distance detector 5, automatically reducing the tensioning force to avoid the tensioning wheel 3 being too large; when the actual distance detected by the distance detector 5 between the sliding seat 41 and the conveyor belt 2 is less than the set distance, the controller 6 controls the tensioning driving member 42 to drive the tensioning wheel 3 to move downward according to the signal fed back by the distance detector 5, automatically increasing the tensioning force to avoid the tensioning wheel 3 being too small.

[0056] The conveying device for reconstituted tobacco leaves further includes a pressing wheel group 7 and a pressing driving member 8. The pressing wheel group 7 is opposite to the tensioning wheel 3 and is respectively arranged on the upper and lower sides of the lower belt 22; the pressing wheel group 7 abuts against the side of the conveyor belt 2 away from the tensioning wheel 3. The pressing wheel group 7 and the tensioning wheel 3 respectively extrude and shape the two opposite sides of the conveyor belt 2, so that the two side surfaces of the conveyor belt 2 are kept flat, solving the problems of curling of the conveyor belt 2 caused by high temperature or unevenness of its surface, ensuring uniform feeding of the conveyor belt 2, and improving the uniformity and efficiency of material conveying. The pressing driving member 8 is fixedly arranged on the bracket 1 and is connected to the pressing wheel group 7. The pressing driving member 8 is used to drive the pressing wheel group 7 to press against the conveyor belt 2.

[0057] The conveying device for reconstituted tobacco leaves further includes a tensioning detector and a pressing detector. The tensioning detector is used to detect the actual tensioning force applied by the tensioning wheel 3 to the conveyor belt 2, and the pressing detector is used to detect the actual pressing force applied by the pressing wheel group 7 to the conveyor belt 2. Both the tensioning detector and the pressing detector can specifically be pressure sensors, but are not limited thereto. The tensioning detector, the pressing detector, the tensioning driving member 42 and the pressing driving member 8 are all connected to the controller 6.

[0058] When the tension detection component detects that the actual tension applied by the tensioning wheel 3 to the conveyor belt 2 is inconsistent with the set tension, the tension detection component feeds back a signal to the controller 6. After receiving the signal, the controller 6 makes a judgment and processing, and sends the generated signal to the tension driving component 42. The tension driving component 42 automatically drives the tensioning wheel 3 to press against or lift off the conveyor belt 2 to achieve automatic tension adjustment.

[0059] When the pressing detection component detects that the actual pressing force applied by the pressing wheel set 7 to the conveyor belt 2 is inconsistent with the set pressing force, the pressing detection component feeds back a signal to the controller 6. After receiving the signal, the controller 6 makes a judgment and processing, and sends the generated signal to the pressing driving component 8. The pressing driving component 8 automatically drives the pressing wheel set 7 to press against or lift off the conveyor belt 2 to achieve automatic pressing force adjustment, ensuring that the tension and pressing force applied to the conveyor belt 2 are appropriate and can effectively perform automatic shaping on the conveyor belt 2.

[0060] As a preferred embodiment, when the tension detection component detects that the actual tension applied by the tensioning wheel 3 to the conveyor belt 2 is greater than the set tension, the controller 6 controls the tension driving component 42 to drive the tensioning wheel 3 to move upward according to the signal fed back by the tension detection component, automatically reducing the tension to avoid the tensioning wheel 3 being too large and the conveyor belt 2 being damaged due to excessive extrusion; when the tension detection component detects that the actual tension applied by the tensioning wheel 3 to the conveyor belt 2 is less than the set tension, the controller 6 controls the tension driving component 42 to drive the tensioning wheel 3 to move downward according to the signal fed back by the tension detection component, automatically increasing the tension to avoid the tensioning wheel 3 being too small and the conveyor belt 2 being slack due to insufficient tension.

[0061] When the pressing detection component detects that the actual pressing force applied by the pressing wheel set 7 to the conveyor belt 2 is greater than the set pressing force, the controller 6 controls the pressing wheel set 7 to move downward according to the signal fed back by the pressing detection component, automatically reducing the pressing force to avoid the pressing force being too large and the conveyor belt 2 being damaged due to excessive extrusion of the conveyor belt 2; when the pressing detection component detects that the actual pressing force applied by the pressing wheel set 7 to the conveyor belt 2 is less than the set pressing force, the controller 6 controls the pressing wheel set 7 to move upward according to the signal fed back by the pressing detection component, automatically increasing the pressing force to avoid the pressing force being too small and not achieving the ideal shaping effect.

[0062] Considering that the curling thickness and uneven concave and convex dimensions of the conveyor belt 2, the pressing wheel set 7 is of a segmented structure. The pressing wheel set 7 includes a plurality of pressing wheels 71 arranged side by side in sequence for performing segmented shaping on different segments of the conveyor belt 2 to ensure the surface of the conveyor belt 2 is neat. The pressing driving component 8 includes a plurality of pressing cylinders 81. All the pressing cylinders 81 are connected to all the pressing wheels 71 in one-to-one correspondence. Each pressing cylinder 81 is used to drive the connected pressing wheel 71 to move relative to the tensioning wheel 3 to press the conveyor belt 2 in segments by the pressing wheels 71. The pressing cylinder 81 can be a pneumatic cylinder for providing the pressing force for the pressing wheel 71.

[0063] The conveying device for reconstituted tobacco leaves further includes a pressure detection member 9, which is used to detect the actual extrusion pressure between each pressing wheel 71 and the tensioning wheel 3, specifically, it can be a pressure sensor. The pressure detection member 9 and all the pressing cylinders 81 are connected to the controller 6.

[0064] When the pressure detection member 9 detects that the actual extrusion pressure between each pressing wheel 71 and the tensioning wheel 3 is inconsistent with the set extrusion pressure, the pressure detection member 9 feeds back a signal to the controller 6. After receiving this signal, the controller 6 makes a judgment and processing, and sends the generated signal to the pressing cylinder 81, automatically starting the pressing cylinder 81 to drive the connected pressing wheel 71 to move, realizing automatic segmented extrusion and shaping of the conveyor belt 2, with a high degree of automation and relatively high production efficiency.

[0065] As a preferred embodiment, when the pressure detection member 9 detects that the actual extrusion pressure between each pressing wheel 71 and the tensioning wheel 3 is greater than the set extrusion pressure, the controller 6 controls the pressing cylinder 81 to contract according to the signal fed back by the pressure detection member 9, and the connected pressing wheel 71 automatically moves downward to reduce the pressing force; when the pressure detection member 9 detects that the actual extrusion pressure between each pressing wheel 71 and the tensioning wheel 3 is less than the set extrusion pressure, the controller 6 controls the pressing cylinder 81 to extend according to the signal fed back by the pressure detection member 9, and the connected pressing wheel 71 automatically moves upward to increase the pressing force.

[0066] The bracket 1 includes an upper support frame 13. The upper support frame 13 is fixedly provided with a fixing plate 14 across it. The cylinders of all the pressing cylinders 81 are fixedly arranged on the fixing plate 14, and the piston rods of all the pressing cylinders 81 pass through the fixing plate 14 and are fixedly connected to the pressing wheels 71, so that the piston rods of the pressing cylinders 81 can stretch relative to the fixing plate 14. The fixing plate 14 is correspondingly provided with through holes for the piston rods to pass through, to avoid interference between the fixing plate 14 and the piston rods of the pressing cylinders 81.

[0067] The conveyor belt 2 includes an upper belt 21 and a lower belt 22 which are distributed up and down. The pressing wheels 71 are in contact with the lower belt 22, and the upper belt 21 is used to convey reconstituted tobacco leaves. The conveying device for reconstituted tobacco leaves further includes a spacing detection member connected to the controller 6. The spacing detection member detects the actual spacing between the adjusting assembly 4 and the upper belt 21, specifically, it can be a distance sensor.

[0068] When the spacing detection member detects that the actual spacing between the adjusting assembly 4 and the upper belt 21 is equal to the set spacing, the spacing detection member feeds back a signal to the controller 6. After receiving this signal, the controller 6 makes a judgment and processing, and sends the generated signal to the tensioning driving member 42 to control the tensioning driving member 42 to automatically stop operating, avoiding the adjusting assembly 4 moving upward excessively and toppling the reconstituted tobacco leaves transported by the upper belt 21, reducing the failure rate and having relatively high reliability.

[0069] It should be noted here that the controller 6 should include a signal receiving unit, a signal judging unit, and a signal sending unit. The signal receiving unit is used to receive the electrical signals sent by detection components such as the distance detection component 5, the tension detection component, the pressing detection component, the pressure detection component 9, or the spacing detection component. The signal judging unit is electrically connected to the signal receiving unit so that the signal judging unit is used to judge whether the signal received by the signal receiving unit is a trigger signal. The signal sending unit is electrically connected to the signal judging unit so that the signal sending unit sends the judgment signal generated by the signal judging unit to an execution component such as the tension driving component 42 or the pressing driving component 8. The specific setting manners of the signal receiving unit, the signal judging unit, and the signal sending unit can refer to the prior art; in the present utility model, only the application scenarios of the above three are changed, rather than a substantial improvement is made to them. Obviously, the controller 6 with this structure is widely applied to existing automatic control devices, such as an MCU, a DSP, or a single-chip microcomputer, etc. The key point of the present utility model is that the controller 6 combines each detection component and each execution component in a one-to-one correspondence.

[0070] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0071] Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
