DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0022] By the person skilled in the art, the parts in the case are sequentially connected, and the specific connection and operation sequence should be referred to the following working principle, and the detailed connection means is the commonly known technology in the art, and the following mainly introduces the working principle and process.

[0023] In the conventional technology, the tobacco cut tobacco collecting device with the weighing function needs to repeatedly stop the conveying belt during the weighing process, which is not efficient and affects the service life of the motor due to frequent opening and closing.

[0024] Therefore, the present application provides a tobacco cut tobacco collecting device with a weighing function, which realizes synchronous collecting and weighing through the cooperation between the supporting plate, the pressure sensor, the bottom plate, the material blocking plate, the rotating assembly and the connecting assembly. During the discharging process, the mesh conveying belt does not need to be stopped, and the tobacco leaves are temporarily blocked by the material blocking plate. When the supporting plate returns to the original position, the tobacco leaves fall again. During the whole process, the conveying of the tobacco leaves is not interrupted, the weighing and collecting efficiency is high, and the driving device of the mesh conveying belt does not need to be frequently opened and closed, which is beneficial to the improvement of the service life.

[0025] From Figure 1 , Figure 3 and Figure 4 , it can be known that the tobacco cut tobacco collecting device with a weighing function comprises a rack 1, the inside of the rack 1 is provided with a mesh conveying belt 2, the inner walls of the mesh conveying belt 2 are attached with supporting rollers 4 on both sides, the supporting rollers 4 are rotationally connected to the rack 1 through bearings, the one side of the mesh conveying belt 2 is provided with a supporting plate 5 below, the bottom of the supporting plate 5 is fixedly connected with a bottom plate 6 through a pressure sensor 7, the bottom of the bottom plate 6 is provided with a rotating assembly, the top of the bottom plate 6 is provided with a cross beam 14 fixedly connected to one end of the inner wall of the rack 1, the cross beam 14 is located above one end of the mesh conveying belt 2, the inner wall top of the cross beam 14 is rotationally connected with a material blocking plate 15 through a pin shaft, and the material blocking plate 15 is drivingly connected to the top of the supporting plate 5 through a connecting assembly.

[0026] In the implementation process, it is worth pointing out that the rack 1 is welded by metal material, which is used as the installation carrier of the tobacco receiving device structure with weighing function. The mesh conveyor belt 2 can be made of metal, plastic or rubber material, and the surface is covered with mesh. The purpose is to reduce the weight of the device. On the other hand, the dust and debris inside the tobacco can be filtered out, which is beneficial to the improvement of the quality of subsequent tobacco processing. The mesh conveyor belt 2 is driven by the mesh conveyor belt 2 between the carrier rollers 4, which realizes the conveying of tobacco. The carrier plate 5 is installed on the top of the bottom plate 6, and the two are fixed by the pressure sensor 7. In this way, the tobacco leaves conveyed by the mesh conveyor belt 2 above the carrier plate 5 can be weighed by the pressure sensor 7 after falling into the carrier plate 5. In order to facilitate recording and weighing, an external controller such as a PLC controller can be connected to the pressure sensor 7. In this way, the weight of the tobacco leaves falling on the top of the carrier plate 5 can be set. When the weight reaches the preset value, the rotation assembly drives the bottom plate 6 and the carrier plate 5 to rotate, which realizes the pouring of tobacco leaves. The workers can use containers to receive them, or additional conveying devices can be configured below the discharging position of the carrier plate 5, which is beneficial to the subsequent quantitative tobacco processing. The rotation assembly can be a hinge and a telescopic motor, or other arbitrary execution devices that can realize the rotation of the bottom plate 6. The rotation assembly needs to be connected to the controller connected to the pressure sensor 7. In this way, the pressure sensor 7 converts the pressure signal into an electrical signal and transmits it to the controller. The controller determines whether to drive the rotation assembly to work according to the preset value. The cross beam 14 is used to install the blocking plate 15. When the rotation assembly drives the bottom plate 6 to rotate, i.e. the carrier plate 5 discharges, the blocking plate 15 is driven to rotate by the connecting assembly, so that the bottom of the blocking plate 15 is attached to the surface of the mesh conveyor belt 2, avoiding the tobacco leaves from falling continuously during the rotation of the carrier plate 5. When the carrier plate 5 is turned back, the blocking plate 15 returns to the original position under the action of gravity, i.e. the vertical state, and is separated from the surface of the mesh conveyor belt 2. At this time, the tobacco leaves on the surface of the mesh conveyor belt 2 can continue to fall into the carrier plate 5. The specific model of the pressure sensor 7 is not limited, as long as it meets the technical solutions described in this embodiment.

[0027] It can be understood that the carrier plate 5 rotates and discharges, which takes a very short time. Through the setting of the rotation assembly, this action can be completed within 1-2 seconds. Therefore, under the interception of the blocking plate 15, a large amount of tobacco leaves on the surface of the mesh conveyor belt 2 will not fall from the side.

[0028] Of course, the blocking plate 15 can be made of hard rubber material, so that there will be no rigid collision between the blocking plate 15 and the mesh conveyor belt 2, which is beneficial to the service life of the two, and will not cause excessive damage to the tobacco leaves.

[0029] In one embodiment, please refer to Figure 1 and Figure 3The rotating assembly comprises the first support 8, the first rotating shaft 9, the second support 10, the second rotating shaft 11, the telescopic rod 12 and the third rotating shaft 13. The first support 8 is fixedly connected to the bottom of the bottom plate 6 near one side of the mesh conveyor belt 2. The inner wall of the first support 8 is fixedly connected with the first rotating shaft 9. The end of the first rotating shaft 9 is rotatably connected with the rack 1 through a bearing. The bottom of the bottom plate 6 is fixedly connected with the second support 10 away from the first support 8. The inner wall of the second support 10 is rotatably connected with the second rotating shaft 11 through a bearing. The outer wall of the second rotating shaft 11 is fixedly connected with the telescopic rod 12. The end of the telescopic rod 12 is fixedly connected with the third rotating shaft 13. The third rotating shaft 13 is rotatably connected with the rack 1 through a bearing.

[0030] In the specific implementation process, it is worth pointing out that the bottom plate 6 is hinged in the interior of the rack 1 through the first support 8 and the first rotating shaft 9. The bottom can be rotated through the installation of the telescopic rod 12, which is beneficial to the discharging of the supporting plate 5. The telescopic rod 12 can adopt a telescopic motor, and the specific model can be selected according to the actual situation.

[0031] In an implementable manner, please refer to Figure 1 、 Figure 2 and Figure 4 The connecting assembly comprises the connecting rod 16, the tension spring 17, the pull rope 18 and the hanging ring 19. The connecting rod 16 is fixedly connected to the side of the blocking plate 15 away from the mesh conveyor belt 2. The lower portion of the connecting rod 16 is provided with the pull rope 18. The connecting rod 16 and the pull rope 18 are provided with the tension spring 17. The bottom of the pull rope 18 is fixedly connected with the hanging ring 19. The bottom of the hanging ring 19 is fixedly connected to the top of the supporting plate 5.

[0032] In the specific implementation process, it is worth pointing out that the purpose of the connecting rod 16 is to change the action point of the tension spring 17. Through the connection of the pull rope 18, the hanging ring 19 and the tension spring 17, the blocking plate 15 can be driven to rotate when the supporting plate 5 is downwardly rotated for discharging, and the bottom thereof is attached to the outer wall of the mesh conveyor belt 2. The purpose of the tension spring 17 is to ensure that the supporting plate 5 starts to rotate, that is, the blocking plate 15 intercepts the materials on the surface of the mesh conveyor belt 2. Therefore, the pull rope 18 should be kept vertical without bending part. However, the hanging ring 19 does not have upward pulling force, so that the influence on the weighing accuracy of the pressure sensor 7 can be avoided. When the angle of the supporting plate 5 is large, the overall movement stroke of the pull rope 18 is large, and the movement stroke of the blocking plate 15 is small. When the blocking plate 15 is attached to the surface of the mesh conveyor belt 2, the difference between the strokes of the two can be compensated through the stretching of the tension spring 17 when the supporting plate 5 continues to rotate, so as to ensure the orderly cooperation of each part, realize the non-stop weighing and material collection of the mesh conveyor belt 2, and avoid the excessive resistance force between the blocking plate 15 and the mesh conveyor belt 2, thereby reducing the load of the driving part of the mesh conveyor belt 2.

[0033] In an implementable mode, referring to Figure 1 The end of one of the carrier rollers 4 is provided with a driving motor 41, which is fixed to the outer wall of the frame 1.

[0034] In the specific implementation process, it is worth pointing out that the specific model of the driving motor 41 is not limited, and it can meet the use requirements, and is used to provide power to the carrier roller 4 to realize the operation of the mesh conveyor belt 2.

[0035] In an implementable mode, referring to Figure 1 and Figure 5 The outer wall of the mesh conveyor belt 2 is fixedly connected with rubber belts 3 on both sides, the inner wall of the rubber belt 3 is attached with a plurality of supporting rollers 21, the outer wall of the supporting roller 21 is fixedly connected with a protrusion 22, the two ends of the supporting roller 21 are rotatably connected with a bracket 20 through a bearing, and the bracket 20 is fixed to the surface of the frame 1.

[0036] In the specific implementation process, it is worth pointing out that the setting of the rubber belt 3 can increase the friction between the mesh conveyor belt 2 and the carrier roller 4, and the purpose of the supporting roller 21 is to support the mesh conveyor belt 2 and the rubber belt 3, and to ensure the smooth conveying of the tobacco leaves, wherein the design of the protrusion 22 realizes that when the protrusion 22 is in contact with and separated from the rubber belt 3 and the mesh conveyor belt 2, the mesh conveyor belt 2 and the rubber belt 3 are synchronous and jolted when the protrusion 22 is driven to rotate by the friction between the rubber belt 3 and the mesh conveyor belt 2, which is beneficial to the tobacco leaves, dust and other substances passing through the mesh conveyor belt 2 and falling on the inner wall of the frame 1, wherein the bottom of the frame 1 is open, so that the substances will fall to the ground, and personnel can clean it regularly to improve the quality of tobacco silk, wherein the supporting roller 21 and the protrusion 22 are made of rubber material, which can rotate with the mesh conveyor belt 2 and the rubber belt 3 under the friction of the mesh conveyor belt 2 and the rubber belt 3, and avoid sliding friction between the supporting roller 21, the mesh conveyor belt 2 and the rubber belt 3 due to the setting of the protrusion 22. Of course, the height of the protrusion 22 can be designed to be smaller, for example, it is smoothly arranged on the outer wall of the supporting roller 21, and the height is between 0.4-1cm.

[0037] Further, the inner wall of the rubber belt 3 is provided with a grinding surface 23.

[0038] In the specific implementation process, it is worth pointing out that the grinding surface 23 is opened on the side of the rubber belt 3 abutting the supporting roller 21 and the carrier roller 4, which is to increase the friction and facilitate synchronous rotation.

[0039] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
