Description

Technical Field

[0001] This utility model relates to the technical field of zongzi leaf drying machines, specifically a box-type zongzi leaf drying machine. Background Technology

[0002] Zongzi leaves have the effects of clearing heat and stopping bleeding, detoxifying and reducing swelling. They have a natural aroma and strong antioxidant, antibacterial and bacteriostatic effects. They are a natural functional food additive and health product raw material. After harvesting, zongzi leaves are generally dried and refrigerated. Dried leaves are easy to preserve for a long time. After processing, they are generally sorted by size and packaged. Refrigerated leaves are generally used as a buffer. Fresh leaves that cannot be dried in time can be temporarily placed in a cold storage. They can also be directly made into fresh zongzi leaves. Zongzi leaf drying machines have an important application in the zongzi leaf processing technology.

[0003] Workers using box-type bamboo leaf dryers must manually lift the frames containing fresh bamboo leaves, bend over, and reach into the drying chamber to place them layer by layer onto the support structure inside. Due to the high moisture content of fresh bamboo leaves, combined with the weight of the frames themselves, a single frame often weighs over ten kilograms. Manual handling is not only extremely labor-intensive, but continuous operation can also lead to operator fatigue and significantly reduce feeding efficiency, making it difficult to meet the production needs of continuous drying of large quantities of bamboo leaves. Therefore, it is necessary to provide a box-type bamboo leaf dryer structure that can achieve automated feeding, reducing labor intensity while meeting the high-efficiency production needs of modern bamboo leaf processing. Utility Model Content

[0004] To address the problem of operator fatigue and significantly reduced feeding efficiency caused by manually handling and placing bamboo leaves in the drying box, this utility model aims to provide a box-type bamboo leaf dryer, thereby achieving the technical effect of reducing labor intensity while meeting the high-efficiency production needs of modern bamboo leaf processing.

[0005] This utility model is a box-type zongzi leaf dryer, including a drying box and a stacking assembly; The stacking assembly includes a fixed shaft, a movable plate, and a stop bar; The fixed shafts are arranged in groups of two, for a total of five groups, and are fixed at equal intervals inside the drying oven. The movable plate is triangular and rotatably sleeved on the outer surface of the corresponding fixed shaft. There are five sets of two stop bars, which are fixed inside the drying oven. The stop bars are located on the outer side above the fixed shaft, and the upper surface of the movable plate is in contact with the outer surface of the stop bars.

[0006] Preferably, the outer surface of the drying oven is hinged with a sealing door, and a fan is fixed to one side of the drying oven.

[0007] Preferably, a fixing plate is fixed to the lower interior of the drying oven, and a placement plate is provided on the upper surface of the fixing plate.

[0008] Preferably, a placement frame is placed on the upper surface of the placement plate, and the placement frame is in contact with the upper surface of the movable plate.

[0009] Preferably, it further includes a drive assembly, which includes a movable hole, a connecting post, and a mounting frame; There are three movable holes, each opened on the surface of the fixed plate and completely penetrating the fixed plate; There are two connecting columns, which are fixed to the lower surface of the placement plate; The connecting column is slidably fitted into two movable holes, and there are two mounting frames, which are respectively fixed to the lower surface of the two connecting columns.

[0010] Preferably, a spring is installed on the upper surface of the mounting frame, and the spring is sleeved on the lower surface of the connecting column, with the upper end of the spring contacting the lower surface of the fixing plate.

[0011] Preferably, a fixing frame is fixed to the rear side of the drying box, an electric push rod is fixed to the upper surface of the fixing frame, and the output end of the electric push rod extends into the interior of the drying box.

[0012] Preferably, the output end of the electric push rod is fixed with a movable block, the movable block is triangular, a rotating wheel is rotatably installed inside the mounting frame, the outer surface of the rotating wheel contacts the upper surface of the movable block, a limit post is fixed on the front side of the placement plate, and the limit post passes through the third movable hole.

[0013] This utility model has the following beneficial effects: This invention utilizes a drying chamber, a sealed door, a fan, and a stacking assembly. A placement frame containing zongzi leaves is placed on a placement plate. Then, an electric push rod is activated, extending and moving a movable block within the drying chamber. The triangular shape of the movable block drives a rotating wheel, which in turn moves a connecting column upwards. This upward movement of the connecting column, in turn, moves the placement plate upwards, causing the placement frame to move upwards. As the placement frame moves upwards, it contacts the lower surface of a movable plate. With the connection of a fixed shaft and the pushing action of the placement frame, the movable plate opens upwards from the inside, allowing the placement frame to pass through. The electric push rod... The push rod shortens further, causing the moving block to move, which in turn moves the connecting column downwards. The connecting column then moves the placement plate downwards simultaneously. Under the influence of gravity, the placement frame moves downwards and is stopped by the stop bar, which locks the movable plate, securing the placement frame in place. The placement plate then moves upwards again, causing the placement frame to automatically and gradually move upwards. This eliminates the need for workers to manually carry the heavy placement frame, bend over, and reach into the drying chamber to place it. The placement frame can be placed on the placement plate, and the mechanical structure driven by the electric push rod can automatically complete the feeding process, effectively reducing manual labor. This is especially suitable for continuous drying of large quantities of zongzi leaves, improving overall operational efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-4 As shown, this utility model is a box-type zongzi leaf dryer, including a drying box 11 and a stacking assembly.

[0020] The stacking assembly includes a fixed shaft 24, a movable plate 25, and a stop bar 26. The fixed shafts 24 are arranged in groups of two, for a total of five groups, and are fixed at equal intervals inside the drying oven 11. The movable plate 25 is triangular and is rotatably fitted onto the outer surface of the corresponding fixed shaft 24; The baffles 26 are arranged in pairs, with a total of five sets, which are fixed inside the drying oven 11. The baffles 26 are located on the outside of the fixed shaft 24, and the upper surface of the movable plate 25 is in contact with the outer surface of the baffles 26. The drying chamber 11 serves as the core space for drying zongzi leaves, providing a stable environment for the drying process. An independent heat circulation zone can be formed inside, which, in conjunction with the hot air delivered by the fan 13, maintains uniform temperature and humidity conditions, ensuring the quality of the dried zongzi leaves. The fixed shaft 24 provides a precise fulcrum for the movable plate 25, allowing it to rotate flexibly around the fixed shaft 24. This satisfies the opening and closing requirements when the placement frame 23 passes upwards, and also allows it to return to its supporting position after placement. When the placement frame 23 moves upwards, its lower surface pushes the movable plate 25 to rotate upwards around the fixed shaft 24, providing a passageway for the placement frame 23. When the placement frame 23 falls onto the upper surface of the movable plate 25, the movable plate 25 remains horizontal under the limit of the stop bar 26, forming a stable support surface, enabling the layered stacking of the placement frames 23. The stop bar 26 serves both limiting and load-bearing functions.

[0021] A sealing door 12 is hinged to the outer surface of the drying oven 11, and a fan 13 is fixed to one side of the drying oven 11; a fixing plate 21 is fixed to the lower end of the interior of the drying oven 11, a placement plate 22 is on the upper surface of the fixing plate 21, a placement frame 23 is placed on the upper surface of the placement plate 22, and the placement frame 23 is in contact with the upper surface of the movable plate 25. The fixed plate 21 provides a stable installation and moving platform for the placement plate 22, ensuring that the placement plate 22 remains horizontal during up and down movement, and preventing the placement frame 23 from shifting or tipping over due to bottom shaking. The placement plate 22 can move up and down in the vertical direction, gradually pushing the placement frame 23 placed on it to the movable plate 25 at different heights, realizing the automated layer-by-layer stacking of the placement frame 23. The bamboo leaves to be dried can be neatly placed inside the placement frame 23, and the hollow design facilitates the penetration of hot air, ensuring that the bamboo leaves are heated evenly.

[0022] Working principle: Place the frame 23 containing the bamboo leaves onto the placement plate 22. Then, activate the electric push rod 32. The electric push rod 32 extends, causing the moving block 33 to move within the drying chamber 11. The triangular shape of the moving block 33 drives the rotating wheel 38 to rotate. The rotating wheel 38 then pushes the connecting column 35 upward. The upward movement of the connecting column 35 causes the placement plate 22 to move upward, which in turn causes the placement frame 23 to move upward. The upward movement of the placement frame 23 brings it into contact with the lower surface of the movable plate 25, where it is fixed. Under the connection of shaft 24 and the push of placement frame 23, movable plate 25 will open from the inside upward, allowing placement frame 23 to pass through movable plate 25. Electric push rod 32 will then shorten, driving moving block 33 to move, causing connecting column 35 to move downward. Connecting column 35 will simultaneously drive placement plate 22 to move downward. Under the action of gravity, placement frame 23 moves downward. Under the obstruction of stop bar 26, movable plate 25 will be stuck, placing placement frame 23 firmly. Placement plate 22 will move upward again, causing placement frame 23 to move upward automatically and gradually. This step eliminates the need for staff to manually carry the heavy placement frame 23, bend over, and reach into the drying chamber 11. Instead, the placement frame 23 is placed on the placement plate 22, and the feeding is automatically completed by the mechanical structure driven by the electric push rod 32. This effectively reduces manual labor and is especially suitable for continuous drying of large quantities of zongzi leaves, improving overall operational efficiency.

[0023] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The drive assembly includes a movable hole 34, a connecting post 35, and a mounting frame 37. There are three movable holes 34, which are respectively opened on the surface of the fixed plate 21 and completely penetrate the fixed plate 21; There are two connecting posts 35, which are fixed to the lower surface of the placement plate 22; The connecting post 35 is slidably sleeved in the two movable holes 34. There are two mounting frames 37, which are fixed on the lower surface of the two connecting posts 35 respectively. A spring 36 is installed on the upper surface of the mounting frame 37, and the spring 36 is sleeved on the lower surface of the connecting post 35. The upper end of the spring 36 is in contact with the lower surface of the fixing plate 21. Three movable holes 34 are formed on the surface of the fixed plate 21 and completely penetrate it, serving as precise guide channels for component movement. Two of the movable holes 34 allow the connecting post 35 to slide and engage, while the third allows the limiting post 39 to pass through. Through the cooperation between the hole wall and the post body, the movement trajectory of the connecting post 35 and the limiting post 39 is strictly limited, ensuring that the placement plate 22 can only rise and fall smoothly in the vertical direction, avoiding tilting of the placement frame 23 or misalignment of the feeding due to deviation. The connecting post 35 can directly convert the upward force transmitted by the mounting frame 37 into the lifting force of the placement plate 22. At the same time, the stability of the lifting process is ensured by the constraint of the movable holes 34. The mounting frame 37 provides rotational installation space for the rotating wheel 38, ensuring that the rotating wheel 38 can flexibly roll against the surface of the moving block 33. When the placement plate 22 rises, the spring 36 is compressed and stores elastic potential energy. When the electric push rod 32 retracts, the spring 36 recovers its deformation and generates a downward thrust, driving the mounting frame 37, the connecting post 35, and the placement plate 22 to quickly return to their original positions.

[0024] A fixed frame 31 is fixed to the rear side of the drying oven 11. An electric push rod 32 is fixed to the upper surface of the fixed frame 31. The output end of the electric push rod 32 extends into the interior of the drying oven 11. A moving block 33 is fixed to the output end of the electric push rod 32. The moving block 33 is triangular. A rotating wheel 38 is rotatably installed inside the mounting frame 37. The outer surface of the rotating wheel 38 contacts the upper surface of the moving block 33. A limit post 39 is fixed to the front side of the placement plate 22. The limit post 39 passes through the third movable hole 34. The fixed frame 31 provides support for the electric push rod 32 through its rigid connection with the drying box 11. The electric push rod 32 performs linear telescopic motion through the output end of the electric drive, which drives the moving block 33 to move horizontally, converting electrical energy into mechanical power, and providing a continuous and controllable driving force for the lifting and lowering of the placement plate 22. The inclined upper surface of the moving block 33 contacts the rotating wheel 38, which can convert the horizontal thrust of the electric push rod 32 into the upward thrust of the rotating wheel 38. The rotating wheel 38 converts the sliding friction between the moving block 33 and the mounting frame 37 into rolling friction, which greatly reduces component wear and extends service life.

[0025] Working principle: Three movable holes 34 are formed on the surface of the fixed plate 21 and completely penetrate it. Two of them are for sliding connection of the connecting post 35, and the third is for the limiting post 39 to pass through, providing precise guidance for the up and down movement of the placement plate 22 and preventing deviation or tilting during movement. The fixed frame 31 is fixed to the rear side of the drying chamber 11, providing a stable installation support for the electric push rod 32 and ensuring stable power output. When the electric push rod 32 is started, its output end drives the triangular moving block 33 to move horizontally within the drying chamber 11. The inclined surface of the moving block 33 contacts the rotating wheel 38 in the mounting frame 37. As the moving block 33 moves horizontally, the triangular moving block 33 moves horizontally within the drying chamber 11. 3. Propulsion: The rotating wheel 38 rolls along the inclined surface and is pushed upward, thereby pushing the mounting frame 37 and the connecting column 35 to move upward synchronously. When the connecting column 35 moves upward, it drives the placement plate 22 and the placement frame 23 above it to rise together, realizing the feeding action. During this process, the spring 36 on the outer surface of the connecting column 35 is squeezed and contracted by the fixing plate 21 and the mounting frame 37. When the electric push rod 32 retracts and drives the moving block 33 to retract, the spring 36 restores its deformation and generates elastic force, pushing the mounting frame 37 and the connecting column 35 to reset downward. The placement plate 22 then falls back to the initial position, waiting for the next feeding. This step eliminates the need for manual lifting of the heavy placement frame 23 and inserting it into the box, completely solving the problem of physical exertion associated with traditional manual feeding and adapting to the needs of large-scale continuous production.
