Description

Technical Field

[0001] This invention relates to the field of flue-cured tobacco raw material feeding technology, specifically to an intelligent feeding device and feeding method for flue-cured tobacco raw materials. Background Technology

[0002] Curing raw tobacco leaves is a core process in tobacco processing. Its purpose is to promote the transformation of chemical components and moisture evaporation within the tobacco leaves by precisely controlling parameters such as temperature, humidity, and ventilation, ultimately obtaining finished tobacco leaves with uniform color and excellent aroma.

[0003] Currently, in the process of curing raw tobacco leaves, the tobacco leaves need to be tied to the outside of the placement rods, and then the placement rods are placed layer by layer in the drying oven for curing. Currently, the loading and unloading of the drying oven is mostly done manually. The speed of manually placing tobacco leaves and placement rods is relatively slow, and it is not possible to quickly complete the loading of a large number of tobacco leaves. When manually unloading in the drying oven, there is a risk of contact with high-temperature equipment, which may result in burns and other safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent feeding device and method for flue-cured tobacco raw materials to solve the problems mentioned in the background art.

[0006] The moving mechanism includes a moving slide and a servo motor that drives the moving slide to slide.

[0007] A linear module is rotatably positioned above the support base. A support plate is rotatably mounted on the movable slide of the linear module. A movable rod and a drive unit for driving the movable rod are slidably mounted in the middle of the support plate. A telescopic rod is retractably mounted on one side of the movable rod.

[0008] A clamping assembly is placed at the ends of the telescopic rod and the movable rod. The clamping assembly includes a connecting plate and an industrial camera for monitoring the quality of the blades. A sliding plate is slidably disposed in the middle of the connecting plate. A shaking part is provided at the bottom of the sliding plate to prevent the flue-cured tobacco raw materials from sticking together. A clamping part is provided on one side of the sliding plate to clamp the flue-cured tobacco raw material placement rod.

[0009] Preferably, the moving mechanism further includes a support base, the moving slide is slidably mounted on the top of the support base, one side of the support base is fixedly connected to a fixed rack, a gear is meshed with the outer side of the fixed rack, a servo motor is fixedly connected to the moving slide, and the output end of the servo motor is fixedly connected to the gear.

[0010] Preferably, a support plate is fixedly connected to the top of the movable slide, and a second servo motor is fixedly connected inside the support plate. The output end of the second servo motor is fixedly connected to the linear module. A reducer is fixedly connected to the movable slide of the linear module. The reducer is a worm gear reducer. A third servo motor is fixedly connected to the input end of the reducer, and the output end of the reducer is fixedly connected to the support plate.

[0011] Preferably, the driving unit includes a drive wheel rotatably mounted on one side of the support plate. The drive wheel is located on the upper and lower sides of the moving rod and is in frictional connection with the moving rod. A servo motor for driving the drive wheel is fixedly connected to one side of the support plate. A limiting sleeve is fixedly connected to one side of the support plate and is slidably connected to the moving rod.

[0012] Preferably, a piston is slidably connected inside the movable rod, the piston is fixedly connected to one end of the telescopic rod, a spring is fixedly connected to the end of the piston away from the telescopic rod, and an air intake valve communicating with the movable rod is fixedly connected to the end of the movable rod.

[0013] Preferably, there are two connecting plates, which are respectively fixed to the ends of the telescopic rod and the moving rod. A limiting rod is fixed to the middle of the connecting plate. The sliding plate is slidably connected to the limiting rod. A spring is sleeved on the outside of the limiting rod and below the sliding plate. An infrared rangefinder is fixed to the top of the connecting plate.

[0014] Preferably, the shaking part includes an electromagnet, and an electromagnet is provided at the top of the sliding plate and at the top of the inner wall of the spring three. The two electromagnets have the same magnetic poles when energized. A pressure sensor is fixedly connected to the bottom of the sliding plate, and the industrial camera is symmetrically fixed to both sides of the sliding plate.

[0015] Preferably, the clamping part includes two limiting rods two fixed to one side of the sliding plate, two grippers symmetrically slidably connected in the middle of the limiting rods two, a spring three sleeved between the end of the limiting rods two and the grippers, two electromagnets two fixed to the middle of the sliding plate, and a permanent magnet fixed to the side of the grippers facing the electromagnets two, and the electromagnets two having the same magnetic poles as the permanent magnets when energized.

[0016] The feeding method for the intelligent feeding device for flue-cured tobacco raw materials includes the following steps:

[0017] Servo motor 1 drives the moving slide to position the linear module in the material picking position. The linear module adjusts the height of the gripper, and servo motor 3 adjusts the orientation of the gripper so that the gripper corresponds to the material.

[0018] The grippers work together to hold the material. The shaking unit shakes the gripped material up and down to prevent it from sticking together. The orientation of the telescopic rod is adjusted by rotating the linear module. During this process, the industrial camera captures images of the material and measures its weight to determine its appearance quality. If the material is not up to standard, it is placed in the storage area by controlling the rotation and displacement of the grippers.

[0019] For materials that have passed the inspection, the lifting and lowering of the grippers, in conjunction with the extension and retraction of the telescopic rod, are used to place the materials layer by layer into the drying oven.

[0020] Compared with the prior art, the beneficial effects of this invention are as follows: The movable slide table achieves high-precision, long-stroke linear movement by driving a gear and a fixed rack through a servo motor, with small positioning error and the ability to cover multiple oven stations; the servo motor drives a linear module to rotate around the Z-axis, and combined with a worm gear reducer (self-locking anti-reverse) and a servo motor adjusting the elevation angle of the support plate, it achieves multi-angle (lateral, rotational, and pitch) coordinated movement of the gripper, flexibly adapting to material handling requirements at different heights and orientations; the drive wheel drives the moving rod to extend and retract through friction, simplifying the mechanical structure; the pneumatic piston and spring are combined... The integrated telescopic rod design offers fast response and high thrust, with dynamically adjustable clamping range to accommodate materials of different sizes. A limiting sleeve and spring ensure stable movement of the moving rod, preventing deviation or overload and enhancing system reliability. Electromagnetic repulsion drives high-frequency vibration of the sliding plate, combined with spring reset, causing continuous micro-vibration of the tobacco leaves during transport, effectively reducing adhesion and accumulation and improving roasting uniformity. An industrial camera captures real-time images of the tobacco leaves, enabling image comparison and quality analysis, and automatic sorting of defective products. A pressure sensor monitors clamping force to prevent overload damage to the tobacco leaves, providing double protection for raw material quality. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 This invention provides a technical solution: an intelligent feeding device for flue-cured tobacco raw materials, comprising: a moving mechanism, the moving mechanism including a moving slide 3 and a servo motor 4 for driving the moving slide 3 to slide; a linear module 8 rotatably positioned above a support base 1, a support plate 11 rotatably mounted on the moving slide of the linear module 8, a moving rod 12 slidably mounted in the middle of the support plate 11 and a driving part for driving the moving rod 12 to move, and a telescopic rod 15 retractably mounted on one side of the moving rod 12; a clamping assembly positioned at the ends of the telescopic rod 15 and the moving rod 12, the clamping assembly including a connecting plate 19 and an industrial camera 32 for monitoring leaf quality, a sliding plate 23 slidably mounted in the middle of the connecting plate 19, a shaking part at the bottom of the sliding plate 23 for preventing flue-cured tobacco raw materials from sticking together, and a clamping part on one side of the sliding plate 23 for clamping the flue-cured tobacco raw material placement rod, with tobacco leaves symmetrically bound to both sides of the placement rod.

[0032] It should be noted that the present invention is equipped with a PLC controller and a corresponding operation panel. The moving mechanism drives the moving rod 12 to move laterally and rotate along the Z-axis through the linear module 8. The drive unit drives the gripper 27 to move through the moving rod 12, and the servo motor 310 can adjust the elevation angle of the moving rod 12 so that the gripper 27 can perform material loading at different positions and heights. When the gripper 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 and performs preliminary analysis during transportation, placing unqualified tobacco leaves in the unqualified area.

[0033] like Figure 1 , 3 As shown, the moving mechanism also includes a support base 1, a moving slide 3 is slidably mounted on the top of the support base 1, one side of the support base 1 is fixedly connected to a fixed rack 2, a gear 5 is meshed with the outer side of the fixed rack 2, 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.

[0034] It should be noted that when the movable slide 3 moves along the length of the support base 1, the servo motor 4 drives the gear 5 to rotate. The gear 5 meshes with the fixed rack 2. Under the reaction of the force, the movable slide 3 moves on the top of the support base 1. Thus, the servo motor 4 drives the movable slide 3 to move on the support base 1, so that the movable slide 3 can drive the gripper 27 to feed materials to different ovens.

[0035] like Figure 2 , 4 As shown in Figure 6, a support plate 6 is fixedly connected to the top of the movable slide 3. A servo motor 7 is fixedly connected inside the support plate 6. The output end of the servo motor 7 is fixedly connected to the linear module 8. A reducer 9 is fixedly connected to the movable slide of the linear module 8. The reducer 9 is a worm gear reducer. A servo motor 10 is fixedly connected to the input end of the reducer 9. The output end of the reducer 9 is fixedly connected to the support plate 11.

[0036] It should be noted that when the movable slide 3 moves, the linear module 8 can be rotated by the servo motor 2 7, and the linear module 8 drives the moving rod 12 to rotate along the z-axis, thereby adjusting the orientation of the gripper 27. This allows the gripper 27 to switch between the material picking and unloading positions. Furthermore, 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, thereby adjusting the elevation angle of the moving rod 12. This allows the linear module 8 to adjust the height of the moving rod 12 while the servo motor 3 10 can adjust the elevation angle of the moving rod 12, enabling different elevation angles to be adjusted at different heights.

[0037] like Figure 2 , 4 As shown in Figure 6, the drive unit includes a drive wheel 13 rotatably mounted on one side of the support plate 11. The drive wheel 13 is placed on the upper and lower sides of the moving rod 12 and is in frictional connection with the moving rod 12. A servo motor 14 for driving the drive 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. The limiting sleeve 18 is slidably connected to the moving rod 12.

[0038] It should be noted that when the relative position of the moving rod 12 and the linear module 8 is adjusted, the servo motor 14 drives the drive wheel 13 to rotate. Under the action of friction, the drive wheel 13 drives the moving rod 1 to move along the axis of the limiting sleeve 18, so that the moving rod 12 can be adjusted in angle with the support plate 11 and can also be extended and retracted, which facilitates the picking and placing of materials in different positions.

[0039] like Figure 3 , 4 As shown in Figure 6, a piston is slidably connected inside the moving rod 12. The piston is fixedly connected to one end of the telescopic rod 15. A spring 16 is fixedly connected to the end of the piston away from the telescopic rod 15. The other end of the spring 16 is fixedly connected to the end of the moving rod 12. An air intake valve 17 communicating with the moving rod 12 is fixedly connected to the end of the moving rod 12.

[0040] It should be noted that the intake valve 17 of this invention is connected to the air source through an electromagnetic reversing valve and an air duct. The spring 16 is in a compressed state in its natural state. When the telescopic rod 15 needs to extend from the moving rod 12 to delay the length of the moving rod 12, high-pressure air is controlled to enter the moving rod 12 through the intake valve 17. Under the action of air pressure, the piston moves towards 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 retract, the air pressure inside the moving rod 12 is reduced, causing the spring 16 to pull the telescopic rod 15 into the moving rod 12, thereby controlling the telescopic rod 15 to extend and retract at one end of the moving rod 12.

[0041] like Figure 4 , 6 As shown in Figures 7 and 8, there are two connecting plates 19, which are respectively fixed to the ends of the telescopic rod 15 and the moving rod 12. A limiting rod 21 is fixed to the middle of the connecting plate 19. The sliding plate 23 is slidably connected to the limiting rod 21. A spring 22 is sleeved on the outside of the limiting rod 21 and below the sliding plate 23. An infrared rangefinder 20 is fixed to the top of the connecting plate 19. The shaking part includes an electromagnet 25. Electromagnets 25 are provided at corresponding positions on the top of the sliding plate 23 and the top of the inner wall of the spring 29. The magnetic poles of the two electromagnets 25 are the same when energized. A pressure sensor 24 is fixed to the bottom of the sliding plate 23. An industrial camera 32 is symmetrically fixed to both sides of the sliding plate 23.

[0042] It should be noted that during the clamping or unloading process, the infrared rangefinder 20 can detect the position of obstacles in front, which facilitates the clamping part to avoid and adjust. After clamping, under the action of the controller and timer, the electromagnet 25 is intermittently energized. When energized, the magnetic poles of the two electromagnets 25 are the same. Under the action of repulsion, 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. This cycle is repeated to make the gripper 27 shake up and down. While preventing the material from sticking together, it can also reduce the overlap and accumulation between tobacco leaves, making the tobacco leaves more dispersed and with a certain gap, which facilitates the heat to bake the tobacco leaves.

[0043] like Figure 4 , 6 As shown in Figures 7 and 8, the clamping part includes two limiting rods 28 fixedly connected to one side of the sliding plate 23. Two grippers 27 are symmetrically slidably connected to the middle of the limiting rods 28. A spring 29 is sleeved between the end of the limiting rods 28 and the grippers 27. Two electromagnets 26 are fixedly connected to the middle of the sliding plate 23. A permanent magnet 30 is fixedly connected to the side of the grippers 27 facing the electromagnets 26. When the electromagnets 26 are energized, they have the same magnetic poles as the permanent magnet 30.

[0044] It should be noted that, in its natural state, the connecting plate 19 drives the gripper 27 to move toward the middle of the sliding plate 23, so that the two grippers 27 are in a closed state. When the electromagnet 26 is energized, under the action of repulsive force, the permanent magnet 30 drives the gripper 27 to move along the limiting rod 28 to both ends and compress the spring 3 29. At this time, the two grippers 27 are in an open state. When the gripper 27 is moved to the outside of the placement rod, the electromagnet 26 is de-energized, and under the action of the spring 3 29, the gripper 27 clamps the placement rod.

[0045] The feeding method for the intelligent feeding device for flue-cured tobacco raw materials includes the following steps:

[0046] Servo motor 4 drives the moving slide 3 to position the linear module 8 in the material-picking position. The linear module 8 adjusts the height of the gripper 27, and servo motor 3 adjusts the orientation of the gripper 27. The height and orientation of the gripper 27 need to be adjusted according to the specific position of the material. This operation is completed by servo motor 3. The height adjustment of the gripper ensures that it docks with the material. Once the gripper 27 docks with the material, the system will perform a clamping operation to ensure that the material is firmly fixed in the gripper. 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, the orientation of the telescopic rod 15 is adjusted, ensuring that the position of the material in the gripper is more accurate. By rotating the linear module 8, the direction and length of the telescopic rod can be precisely adjusted, preventing tilting or misalignment of the material during clamping and ensuring it enters the next working stage in the predetermined direction. During this process, the industrial camera 32 acquires images and measures the weight of the material to determine its appearance quality. Once the material is clamped and in the appropriate position, the industrial camera 32 begins real-time image acquisition. After capturing the material's appearance, the image processing system analyzes the data to determine its quality. Additionally, the system performs weight measurement to ensure each piece of material meets production standards by checking if the weight is within a specified range. Through image processing and weighing technology, the system determines whether the material is qualified. Unqualified materials are placed in the receiving area by controlling the rotation and displacement of the gripper 27. For qualified materials that pass the appearance and weight tests, the system continues processing. At this point, the gripper 27 operates by lifting and lowering the material according to its position and condition, placing it with the aid of the telescopic rod 15 and feeding it layer by layer into the drying oven for further processing. The telescopic rod's extension and retraction helps to precisely deliver materials into the designated location within the oven, while ensuring that the materials are stacked neatly and without tilting or obstruction.
