Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 8 The present invention provides a technical solution: an intelligent feeding device for flue-cured tobacco raw materials, comprising: a moving mechanism, the moving mechanism comprising a moving slide 3 and a servo motor 4 for driving the moving slide 3 to slide; a linear module 8 is rotatably placed above a support seat 1, a support plate 11 is rotatably arranged on the moving slide of the linear module 8, a moving rod 12 and a driving part for driving the moving rod 12 to move are slidably arranged in the middle of the support plate 11, and a telescopic rod 15 is telescopically arranged on one side of the moving rod 12; a clamping assembly is placed at the ends of the telescopic rod 15 and the moving rod 12, the clamping assembly comprises a connecting plate 19 and an industrial camera 32 for monitoring the quality of leaves, a sliding plate 23 is slidably arranged in the middle of the connecting plate 19, a shaking part is arranged at the bottom of the sliding plate 23 for preventing the flue-cured tobacco raw materials from sticking, and a clamping part is arranged on one side of the sliding plate 23 for clamping the flue-cured tobacco raw materials and placing the rod, and tobacco leaves are symmetrically bundled on both sides of the placing rod.

[0019] It should be noted that the present invention is provided with a PLC controller and a corresponding operation panel. The moving mechanism drives the moving rod 12 to move horizontally and rotate along the Z axis through the linear module 8. The driving part drives the clamping jaw 27 to move through the moving rod 12, and cooperates with the servo motor 3 10 to adjust the elevation angle of the moving rod 12, so that the clamping jaw 27 can load materials at different positions and heights. When the clamping jaw 27 fixes the material, the pressure sensor 24 can detect the weight of the material, and the shaking part makes the material vibrate up and down to prevent the material from sticking together and scattering during transportation. The industrial camera 32 takes pictures of the transported tobacco leaves for comparison, performs a preliminary analysis on them during transportation, and places unqualified tobacco leaves in the unqualified area.

[0020] like Figure 1 , 3 As shown, the moving mechanism also includes a support base 1, a moving slide 3 is slidably installed on the top of the support base 1, one side of the support base 1 is fixedly connected to the fixed rack 2, the outer side of the fixed rack 2 is meshed with a gear 5, a servo motor 4 is fixedly connected to the moving slide 3, and the output end of the servo motor 4 is fixedly connected to the gear 5.

[0021] It should be noted that when the present invention drives the movable slide 3 to move along the length direction of the support base 1, the servo motor 4 drives the gear 5 to rotate, and the gear 5 is meshed and connected with the fixed rack 2. Under the reaction of the force, the movable slide 3 moves on the top of the support base 1, thereby driving the movable slide 3 to move on the support base 1 through the servo motor 4, so that the movable slide 3 can drive the clamp 27 to load materials corresponding to different ovens.

[0022] like Figure 2 , 4 As shown in , 6, the top of the movable slide 3 is fixedly connected to a support plate 6, the interior of the support plate 6 is fixedly connected to a servo motor 2 7, the output end of the servo motor 2 7 is fixedly connected to a linear module 8, the movable slide of the linear module 8 is fixedly connected to a reducer 9, the reducer 9 is a worm gear reducer, the input end of the reducer 9 is fixedly connected to a servo motor 3 10, and the output end of the reducer 9 is fixedly connected to a support plate 11.

[0023] It should be noted that, in the present invention, when the movable slide 3 moves, the servo motor 2 7 can drive the linear module 8 to rotate, and the linear module 8 drives the moving rod 12 to rotate along the z-axis, so as to adjust the orientation of the clamp 27, so that the clamp 27 can be switched between the material picking and material discharging positions, and the servo motor 3 10 drives the support plate 11 to rotate through the reducer 9, and the support plate 11 drives the moving rod 12 to rotate, so as to adjust the elevation angle of the moving rod 12, so that the linear module 8 can adjust the height of the moving rod 12, and the servo motor 3 10 can adjust the elevation angle of the moving rod 12 at the same time, so that different elevation angles can be adjusted at different heights.

[0024] like Figure 2 , 4 As shown in , 6, the driving part includes a driving wheel 13 rotatably mounted on one side of the support plate 11, the driving wheel 13 is placed on the upper and lower sides of the moving rod 12 and is frictionally connected to the moving rod 12, a servo motor 14 for driving the driving wheel 13 is fixedly connected to one side of the support plate 11, a limiting sleeve 18 is fixedly connected to one side of the support plate 11, and the limiting sleeve 18 is slidably connected to the moving rod 12.

[0025] It should be noted that, when the present invention adjusts the relative position of the moving rod 12 and the linear module 8, the servo motor 14 drives the driving wheel 13 to rotate, and the driving wheel 13 drives the moving rod 1 to move along the axial direction of the limiting sleeve 18 under the action of friction, so that the moving rod 12 can follow the support plate 11 to adjust the angle and can be telescopically adjusted at the same time, which is convenient for taking and placing materials at different positions.

[0026] like Figure 3 , 4 As shown in Figure 6, the movable rod 12 is internally slidably connected with a piston, the piston is fixedly connected to one end of the telescopic rod 15, the end of the piston away from the telescopic rod 15 is fixedly connected to a spring 16, the other end of the spring 16 is fixedly connected to the end of the movable rod 12, and the end of the movable rod 12 is fixedly connected to an intake valve 17 connected to the movable rod 12.

[0027] It should be noted that the air intake valve 17 of the present invention is connected to the air source through the electromagnetic reversing valve and the air duct, and the natural state of the spring 16 is a compressed state. When the telescopic rod 15 needs to be extended from the moving rod 12 to delay the length of the moving rod 12, the high-pressure gas is controlled to enter the moving rod 12 through the air intake valve 17. Under the action of the air pressure, the piston moves toward one end of the moving rod 12 and stretches the spring 16 to adjust the extension of the telescopic rod 15. When the telescopic rod 15 needs to be retracted, the air pressure inside the moving rod 12 is reduced, so that the spring 16 pulls the telescopic rod 15 toward the inside of the moving rod 12, thereby controlling the telescopic adjustment of the telescopic rod 15 at one end of the moving rod 12.

[0028] like Figure 4 , 6 As shown in , 7 and 8, two connecting plates 19 are provided and are respectively fixed on the ends of the telescopic rod 15 and the movable rod 12, a limiting rod 21 is fixed on the middle part of the connecting plate 19, a sliding plate 23 is slidably connected to the limiting rod 21, a spring 22 is sleeved on the outer side of the limiting rod 21 and located below the sliding plate 23, an infrared rangefinder 20 is fixed on the top of the connecting plate 19, a shaking part includes an electromagnet 25, an electromagnet 25 is provided at the corresponding position of the top of the sliding plate 23 and the top of the inner wall of the spring 3 29, the two electromagnets 25 have the same magnetic poles when energized, a pressure sensor 24 is fixed on the bottom of the sliding plate 23, and an industrial camera 32 is symmetrically fixed on both sides of the sliding plate 23.

[0029] It should be noted that, in the process of clamping or discharging materials, the infrared rangefinder 20 of the present invention can detect the position of the obstacle in front, so that the clamping part can avoid and adjust. After clamping is completed, under the action of the controller and the timer, the electromagnet 25 is controlled to be intermittently energized. When energized, the magnetic poles of the two electromagnets 25 are the same. Under the action of repulsive force, the sliding plate 23 moves downward along the limit rod 21 and compresses the spring 22. When the electromagnet 25 is de-energized, the spring 22 drives the sliding plate 23 to reset, and the cycle is repeated to realize the reciprocating shaking of the clamping jaws 27 up and down. While preventing the material from sticking together, it can reduce the overlap and accumulation of tobacco leaves, make the tobacco leaves more dispersed, and have a certain gap, which is convenient for heat to bake the tobacco leaves.

[0030] like Figure 4 , 6 As shown in Figures 7 and 8, the clamping portion includes two limit rods 28 fixedly connected to one side of the sliding plate 23, the middle part of the limit rods 28 is symmetrically slidably connected with two clamping claws 27, a spring 29 is sleeved between the end of the limit rods 28 and the clamping claws 27, the middle part of the sliding plate 23 is fixedly connected with two electromagnets 26, the clamping claw 27 is fixedly connected with a permanent magnet 30 on one side of the electromagnet 26, and the electromagnet 26 has the same magnetic pole as the permanent magnet 30 when energized.

[0031] It should be noted that, in the natural state of the present invention, the connecting plate 19 drives the clamping jaws 27 to move toward the middle of the sliding plate 23, so that the two clamping jaws 27 are in a closed state. When the electromagnet 26 is energized, under the action of the repulsive force, the permanent magnet 30 drives the clamping jaws 27 to move toward both ends along the limit rod 28 and compresses the spring 3 29. At this time, the two clamping jaws 27 are in an open state. When the clamping jaws 27 are moved to the outside of the placement rod, the electromagnet 26 is de-energized, and under the action of the elastic force of the spring 3 29, the clamping jaws 27 clamp the placement rod.

[0032] The feeding method for the intelligent feeding device of flue-cured tobacco raw materials comprises the following steps: Servo motor 1 4 drives the mobile slide 3 to put the linear module 8 in the material picking position. The linear module 8 adjusts the height position of the clamp 27, and the servo motor 3 10 adjusts the orientation position of the clamp 27. The height and orientation of the clamp 27 need to be adjusted according to the specific position of the material. This operation is completed by servo motor 3 10. The height adjustment of the clamp can ensure that it docks with the material; once the clamp 27 docks with the material, the system will perform a clamping operation to ensure that the material is firmly fixed in the clamp. In order to prevent material adhesion or blockage caused by contact, the shaking unit will shake the clamped material up and down to prevent material adhesion. By driving the rotation of the linear module 8 to adjust the orientation of the telescopic rod 15, the orientation of the telescopic rod 15 will be adjusted to ensure that the position of the material in the clamp is more accurate. By driving the rotation of the linear module 8, the direction and length of the telescopic rod can be accurately adjusted, so that the material can be prevented from tilting or dislocating during the clamping process, ensuring that the material can enter the next working link in the predetermined direction. During this period, the industrial camera 32 collects images and weighs the material to determine its appearance quality. When the material is clamped and in a suitable position, the industrial camera 32 starts to collect real-time images of the material. After the camera captures the appearance of the material, it analyzes it through the image processing system to determine the appearance quality of the material. In addition, the system will also perform weighing measurement to ensure that the quality of each material meets the production standards by whether the weight is within the specified range. Through image processing and weighing technology, the system can determine whether the material is qualified. If it is unqualified, it will be placed in the storage area by controlling the rotation displacement of the clamp 27; for qualified materials that pass the appearance quality and weighing test, the system continues to process the material. At this time, the clamp 27 will perform lifting and lowering operations according to the position and state of the material, place the material with the help of the telescopic rod 15, and send it layer by layer into the oven for subsequent processing. The telescopic action of the telescopic rod helps to deliver the material precisely to the designated position of the oven, while ensuring that the material is stacked neatly without tilting or obstruction.
