Description

Technical Field

[0001] The present invention relates to the technical field of tobacco leaf loading on a kang, and more particularly to a mechanically linked tobacco leaf loading tray on a kang. Background Art

[0002] A standard air-source heat pump intensive flue-curing barn (hereinafter referred to as the flue-curing barn) features a three-tiered structure, with the bottom flue-curing barn 1.8 meters above the ground, the middle flue 2.1 meters, and the top flue 2.9 meters. Fresh tobacco leaves must be quickly loaded onto the hot bed for curing after harvest. The traditional manual loading process is cumbersome: the leaves are first loaded into tobacco clips, which are then individually loaded onto the flue-curing barn flue-curing barns. Each clip holds approximately 20 kilograms of tobacco leaves, and a single flue-curing barn can accommodate approximately 380 clips. According to practical calculations, loading a flue-curing barn requires three strong workers working collaboratively for three hours. If 20 flue-curing barns were to be operated simultaneously, the labor requirements would increase significantly. Furthermore, during the flue-curing season from July to September, the flue-curing barns are subjected to unbearable temperatures. The high flue-curing barns on the middle and top flue tiers not only impose high labor intensity on workers but also pose safety risks. Furthermore, prolonged, high-intensity work can easily lead to fatigue, significantly reducing loading efficiency and severely impacting the flue-curing progress and quality.

[0003] Currently, most tobacco loading equipment on the market relies on a lifting mechanism. This traditional system has numerous drawbacks in practical application. First, during loading, tobacco clips must be placed individually into the flue-curing barn, a cumbersome process that severely restricts efficiency. Second, unloading tobacco is not mechanized, and is performed manually, requiring the clips to be removed one by one, a time-consuming and labor-intensive operation. Third, due to the extremely limited space within the flue-curing barn, the single-row structure is only 1.39 meters wide and 8 meters long, resulting in a long and narrow layout. In this environment, loading and unloading carts face strict size constraints and are also significantly restricted in their operation. During loading and unloading, the equipment must be repeatedly adjusted to avoid collisions with the flue-curing barn walls. This process is not only cumbersome but also poses a potential threat to the safety of on-site workers. While this type of equipment alleviates manual labor to a certain extent, actual operation has exposed problems such as low efficiency and limited operational flexibility. It also poses high safety risks, making it difficult to meet the requirements of efficient and safe production.

[0004] Therefore, how to achieve full automation of tobacco leaf loading and unloading and effectively ensure the continuity and efficiency of the entire process of tobacco leaf baking processing is an urgent problem that technical personnel in this field need to solve. Summary of the Invention

[0005] In view of this, the present invention provides a mechanically linked tobacco leaf loading tray, aiming to solve the above technical problems.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A mechanically linked tobacco leaf tray for loading tobacco leaves on a kang, comprising two parallel arranged "J"-shaped tobacco beams, a plurality of trays being slidably arranged between the two "J"-shaped tobacco beams, the trays being provided with a plurality of tobacco clips; a quick locking and unlocking structure being formed between the two corresponding trays;

[0008] The quick locking and unlocking structure includes an upper locking portion provided at the front end of the tray and a lower locking portion provided at the rear end of the tray; the upper locking portion includes an upper locking portion rotatably connected to the inner wall of the frame of the tray via a first axis, the lower portion of the first axis having an upper locking portion support block fixed to the inner wall of the frame and abutting against the upper locking portion; the lower locking portion includes a lower swing arm rotatably connected to the inner wall of the frame via a second axis, the lower swing arm being rotatably connected to a spoon-shaped lower locking portion via a third axis;

[0009] When the two trays need to be connected, the lower lock buckle of the front tray rotates and extends out of the frame and rests on the "J" cigarette beam. The rear tray approaches, so that its frame can push the lower lock buckle to rotate and lift it up and enter the interior of its frame, and push the upper lock buckle to rotate to achieve locking; when the two trays need to be separated, the rear tray is pulled out of the "J" cigarette beam and moves downward, so that the lower lock buckle rotates and disengages from the upper lock buckle.

[0010] Through the above technical solution, the present invention innovates the locking mechanism design and creates a linked tray push system. This automatically triggers the locking mechanism during loading and intelligently releases the mechanism during unloading. This eliminates the need for loading and unloading equipment in and out of the cramped flue-curing room, effectively avoiding safety risks such as collisions and falls, and providing reliable safety for workers. The locking mechanism is ingeniously designed, achieving automatic locking and release functions. When the two trays are tightly fitted, the cigarette holders can be cleverly stored inside the trays, fully freeing up the smoke beam space in the smoke room and effectively improving the load utilization rate of the smoke room.

[0011] Preferably, in the aforementioned mechanically linked tobacco leaf loading tray, the bottom edges of the tray frame are provided with needle bearings on both sides to achieve sliding fit between the frame and the "J"-shaped tobacco beam. By providing needle bearings on both sides of the bottom edges of the tray frame to achieve sliding fit between the frame and the "J"-shaped tobacco beam, the movement resistance during tobacco loading and unloading is significantly reduced, effectively improving the smoothness of the tray movement, reducing energy consumption, and extending the service life of the equipment.

[0012] Preferably, in the aforementioned mechanically linked tobacco leaf loading tray, the bottom edges of both sides of the tray frame are provided with automatic guide blocks. Equipped with a precise guide mechanism, it has automatic positioning and guiding functions, which can accurately limit the lateral displacement of the tray, and avoid obstacles such as bolts on the tobacco beam in real time, ensuring smooth operation of the tray during loading and unloading, reducing equipment wear and the risk of failure.

[0013] Preferably, in the aforementioned mechanically linked tobacco loading tray, a cigarette clip stopper is fixed at the front end of the tray to prevent the cigarette clip from falling out of the front end when loaded. A cigarette clip stopper is fixed at the rear end of the tray to prevent the cigarette clip from falling out of the rear end when loaded, thereby improving the stability and reliability of tobacco loading.

[0014] Preferably, in the above-mentioned mechanically linked tobacco leaf loading tray, when the lower swing arm rotates to abut against the rear end bottom edge of the frame of the tray, the lower lock buckle naturally hangs down outside the frame, and when the tray is pushed onto the "J"-shaped tobacco beam and the "J"-shaped tobacco beam contacts the lower lock buckle, the lower lock buckle is lifted up and placed on the "J"-shaped tobacco beam, further optimizing the automatic positioning and locking functions of the lock buckle.

[0015] Preferably, in the above-mentioned mechanically linked tobacco leaf loading tray, when the cigarette clip needs to be loaded into the frame of the tray, the lower lock buckle is pushed upward to rotate the lower swing arm forward until the end of the lower lock buckle abuts against the top edge of the rear end of the frame of the tray, completing the folding of the lower lock buckle and the lower swing arm, so that an escape space for the cigarette clip to enter is formed under the lower lock buckle and the lower swing arm, simplifying the cigarette clip loading operation process.

[0016] Preferably, in the above-mentioned mechanically linked tobacco leaf loading tray, when the two trays connected front and rear are both located on the "J"-shaped tobacco beam, the lower locking buckles and the upper locking buckles connected front and rear always remain in a locked state. When the rear end tray of the two trays connected front and rear is separated from the "J"-shaped tobacco beam and moves downward, the lower locking buckles and the upper locking buckles connected front and rear are disengaged and unlocked, realizing the automatic tripping function between the trays, which is convenient for unloading operations.

[0017] Preferably, in the above-mentioned mechanically linked tobacco leaf loading tray, the front bottom edge of the frame of the tray can lift the lower lock buckle to connect with the hook head on the upper lock buckle, ensuring the stable connection of the lock buckles between the trays and improving the stability of the pallet during the loading process.

[0018] Preferably, in the above-mentioned mechanically linked tobacco leaf loading tray, the number of the tobacco clips on each tray is 5. Compared with the traditional loading method, it can significantly improve the tobacco leaf loading density in the curing room and improve the space utilization rate of the curing room.

[0019] It can be seen from the above technical solution that, compared with the prior art, the present invention provides a mechanically linked tobacco leaf loading tray, which has the following beneficial effects:

[0020] 1. Innovation in efficient loading and unloading: Breaking through the bottleneck of traditional tobacco loading efficiency, a single pallet can load 5 tobacco clips at a time. Combined with professional loading and unloading equipment, it can achieve rapid and continuous loading and unloading of tobacco leaves in the entire tobacco room, significantly improving operating efficiency and greatly shortening the tobacco leaf loading cycle.

[0021] 2. Upgraded safety protection: The innovative locking structure design creates a tray linkage push system. The locking mechanism is automatically triggered when loading smoke, and the intelligent release is achieved when unloading smoke. There is no need to load and unload equipment in and out of the narrow space of the baking room, effectively avoiding safety risks such as collisions and falls, and providing reliable safety protection for operators.

[0022] 3. Optimized Space Utilization: The ingenious locking mechanism not only achieves automatic locking and releasing functions, but also allows the clamps to float in the air during the loading phase, ensuring smooth and interference-free loading. When the two trays are tightly fitted, the clamps can be cleverly stored inside the trays, fully freeing up the smoke beam space in the smoke room and effectively improving the loading efficiency of the smoke room.

[0023] 4. Precision guidance guarantee: Equipped with a precise guidance mechanism, it has automatic positioning and guidance functions, which can accurately limit the lateral displacement of the pallet, avoid obstacles such as bolts on the smoke beam in real time, ensure the smooth operation of the pallet during loading and unloading, and reduce equipment wear and failure risks.

[0024] 5. Significantly reduced resistance: The bottom of the tray is equipped with a high-precision needle bearing. By optimizing the rolling friction design, the movement resistance during the loading and unloading process is greatly reduced, effectively improving the smoothness of the tray movement, reducing energy consumption, and extending the service life of the equipment.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See attached Figure 1 To the attached Figure 2 The embodiment of the present invention discloses a mechanical linkage tobacco leaf loading tray for a kang, comprising two parallel arranged "J"-shaped tobacco beams 1, a plurality of trays 2 being slidably arranged between the two "J"-shaped tobacco beams 1, and a plurality of tobacco clips 3 being mounted on the trays 2; a quick locking and unlocking structure is formed between the two corresponding trays 2;

[0039] The quick locking and unlocking structure includes an upper locking portion provided at the front end of the tray and a lower locking portion provided at the rear end of the tray; the upper locking portion includes an upper locking portion 203 rotatably connected to the inner wall of the frame 201 of the tray 2 via a first axis 202, and the lower portion of the first axis 202 has an upper locking portion support block 204 fixed to the inner wall of the frame 201 and abutting against the upper locking portion 203; the lower locking portion includes a lower swing arm 206 rotatably connected to the inner wall of the frame 201 via a second axis 205, and the lower swing arm 206 is rotatably connected to a spoon-shaped lower locking portion 208 via a third axis 207;

[0040] When it is necessary to connect the two pallets 2, the lower lock buckle 208 of the front pallet 2 is rotated and extended out of the frame 201, and is placed on the "J"-shaped cigarette beam 1. The rear pallet 2 approaches, so that its frame 201 can push the lower lock buckle 208 to rotate and lift it up and enter the interior of its frame 201, and push the upper lock buckle 203 to rotate to achieve the snap connection; when it is necessary to separate the two pallets 2, the rear pallet 2 is pulled out of the "J"-shaped cigarette beam 1 and moves downward, so that the lower lock buckle 208 rotates and disengages from the upper lock buckle 203.

[0041] Through scientific layout and precise assembly, each component forms a stable and flexible mechanical system, ensuring precise guidance and reliable fixation during the loading, transportation and unloading of tobacco leaves, providing solid hardware support for tobacco baking operations.

[0042] See attached Figure 2 and attached Figure 3 The bottom edges of both sides of the frame 201 of the tray 2 are provided with needle bearings 209 to achieve sliding fit between the frame 201 and the "Ji" cigarette beam 1.

[0043] In order to further optimize the above technical solution, the bottom edges of both sides of the frame 201 of the tray 2 are provided with automatic guide blocks 210 .

[0044] In order to further optimize the above technical solution, a cigarette clip limiting block 211 is fixed at the front end of the tray 2 to prevent the cigarette clip 3 from falling out from the front end when it is installed.

[0045] In order to further optimize the above technical solution, when the lower swing arm 206 rotates to abut the rear end bottom edge of the frame 201 of the tray 2, the lower lock buckle 208 naturally hangs down outside the frame 201, and when the tray 2 is pushed onto the "J"-shaped cigarette beam 1, and the "J"-shaped cigarette beam 1 contacts the lower lock buckle 208, the lower lock buckle 208 is lifted up and placed on the "J"-shaped cigarette beam 1.

[0046] In order to further optimize the above technical solution, when it is necessary to load the cigarette clip 3 into the frame 201 of the tray 2, the lower lock buckle 208 is pushed upward, so that the lower swing arm 206 rotates forward until the end of the lower lock buckle 208 abuts against the top edge of the rear end of the frame 201 of the tray 2, completing the folding of the lower lock buckle 208 and the lower swing arm 206, so that an escape space for the cigarette clip 3 to enter is formed under the lower lock buckle 208 and the lower swing arm 206.

[0047] See attached Figure 4The loading direction of the cigarette clips 3 follows the operating specifications of from outside the tobacco room to inside the tobacco room (as shown in the figure, from right to left). During the preparation phase for loading cigarettes, the lower locking buckle 208 and the lower swing arm 206 need to be rotated to the specific angle shown in the figure. At this time, the two achieve mechanical balance under the coordinated action of gravity and the frame 201, and stably float in the air, reserving sufficient operating space for the rapid assembly of the cigarette clips 3. When a single tray 2 completes the loading of 5 cigarette clips, the cigarette clip limit block 211 immediately takes effect. Through the precise positioning design, it effectively prevents the cigarette clips 3 from accidentally falling off during the subsequent assembly and transportation process, comprehensively ensuring the safety and stability of tobacco loading and significantly improving operational reliability.

[0048] In order to further optimize the above technical solution, when the two trays 2 connected front and rear are both located on the "J"-shaped cigarette beam 1, the lower lock buckle 208 and the upper lock buckle 203 connected front and rear always remain in a locked state. When the rear end tray 2 of the two trays 2 connected front and rear is separated from the "J"-shaped cigarette beam 1 and moves downward, the lower lock buckle 208 and the upper lock buckle 203 connected front and rear are disengaged and unlocked.

[0049] In order to further optimize the above technical solution, the front bottom edge of the frame 201 of the tray 2 can lift the lower lock buckle 208 until it is connected to the hook head on the upper lock buckle 203.

[0050] In this embodiment, the number of cigarette clips 3 on each tray 2 is five.

[0051] See attached Figure 5 After the cigarette clip 3 is loaded, enter Figure 5 In the state shown in a, the operator manually adjusts the lower arm 206 and the lower lock 208. Under the action of gravity, the lower arm 206 is firmly placed on the surface of the cigarette holder 3, and the lower lock 206 naturally droops to form the initial locking preparation posture. When the lifting mechanism accurately raises the push plate to the corresponding height of the cigarette beam ( Figure 5 b) The kang-installing equipment applies a thrust toward the interior of the smoke room (to the left for short), and thanks to the built-in guide mechanism, the tray 2 can be smoothly inserted along the "J"-shaped smoke beam 1. The automatic guide block 210 at the bottom of the tray 2 can limit the lateral position of the tray 2, effectively avoiding the risk of interference with the smoke beam bolts; and the use of the needle bearing 209 greatly reduces the resistance to the movement of the tray 2. When the tray 2 is fully pushed into the "J"-shaped smoke beam 1, the lower lock buckle 208 is interfered with by the structure of the "J"-shaped smoke beam 1 and automatically falls to the plane of the "J"-shaped smoke beam 1, completing the initial positioning.

[0052] In the process of continuous advancement ( Figure 5 c) The subsequent tray 2 and the preceding tray 2 are mechanically linked. The subsequent cigarette holder 3 contacts the lower lock 208 of the preceding tray 2 to form interference. As the subsequent tray 2 continues to move left, the lower lock 208 rotates counterclockwise with the rotation axis as the fulcrum and rises. When the lower lock 208 is completely raised to the upper surface of the cigarette holder 3 ( Figure 5d), continue to push forward, the lower lock buckle 208 and the upper lock buckle 203 produce a second interference, causing the upper lock buckle 203 to rotate clockwise and lift up. Figure 5 e) The hooks are completely retracted into the tray 2, completing the mechanical locking process between the trays 2. Subsequently, the subsequent tray 2 pushes the previous tray 2 through a linkage transmission mechanism, enabling seamless installation of the entire row of trays 2 within the oven, efficiently completing the entire loading operation.

[0053] In the tobacco leaf unloading operation scenario, Figure 6 As shown in a, when the subsequent tray 2 moves to the right, its upper lock 203 precisely hooks the lower lock 208 of the previous tray 2. Affected by the height of the cigarette holder 3, the two hooks form a stable locked state, achieving reliable binding between the trays 2 and providing a solid connection foundation for overall unloading. As the subsequent tray 2 continues to move to the outside of the smoking room ( Figure 6 b) The lifting mechanism is activated, driving tray 2 downward. At this point, under the action of its own weight, the lower latch 208 of the preceding tray 2 rotates clockwise around the rotation axis until it naturally droops, freeing up sufficient space for the following tray 2 to move downward. Ultimately, the two trays 2 are completely separated, completing the critical decoupling operation in the tobacco unloading process.

[0054] This embodiment innovatively designs mechanically linked pallets. The tobacco bed loading equipment is placed outside the tobacco flue-curing room. During the tobacco bed loading process, the pushing mechanism loads the pallets onto the tobacco beams one by one. The later loaded pallets push the previous pallets deeper into the flue-curing room, realizing continuous loading of the entire row of tobacco leaves. At the same time, the pallet locks are locked to prepare for unloading the tobacco. During the tobacco unloading stage, the entire row of pallets can be driven to move outward synchronously by pulling out the pallet closest to the flue-curing room door on each layer of tobacco beam in reverse and onto the equipment lifting system. When the pallet descends with the lifting system, the linkage device will automatically disengage. This loading and unloading mode of the front and rear pallets linkage eliminates the need for supporting equipment to enter the flue-curing room, reduces the occurrence of production safety accidents, and greatly improves the efficiency of tobacco loading and unloading, reduces labor intensity, improves equipment utilization, and realizes the automation and intensive management of tobacco leaf baking operations.

[0055] This embodiment incorporates a guide mechanism that adaptively guides the pallet during docking with the tobacco beam, enabling automatic calibration and precise positioning of the pallet's lateral position, ensuring efficient and error-free loading. As the pallet moves along the tobacco beam, the guide mechanism avoids obstacles such as locking bolts on the beam and columns, ensuring smooth and stable operation, effectively preventing collisions and wear, and significantly improving the safety and reliability of tobacco loading and unloading.

[0056] This tray's structural design achieves a perfect balance between loading capacity and practical performance. By optimizing the load-bearing layout and tray structure, it ensures durability and ease of operation while enabling stable loading of multiple tobacco clips at once. This design significantly improves work efficiency, effectively shortens operation time, and provides strong support for the efficient operation of the tobacco leaf curing process.

[0057] This pallet is the core carrying tool used in the self-developed and published invention patent "CN119699623A A Tobacco Loading Equipment". It has a built-in mechanical linkage device, which can realize automatic locking and release functions during operation. When loading the tobacco leaf, the loading equipment is placed outside the flue-curing room and locked with the flue-curing room columns to prevent misalignment. The pallet is placed on the equipment's lifting device. One pallet can carry five tobacco clips. By cooperating with the loading equipment, five tobacco clips can be automatically loaded on the flue at one time. The adjacent pallets installed on the tobacco beam are locked by the action of the lock to complete the loading. After the tobacco leaves are cured, the propulsion system on the equipment pulls the pallet closest to the flue door out to the lifting system. Under the action of the lock, the internal pallet is pulled outward. When the pallet descends with the lifting system, it can be automatically released, and then the pallets are unloaded from the flue one by one. The design of the pallet can realize the full automation of tobacco leaf loading and unloading, effectively ensuring the continuity and efficiency of the entire process of tobacco leaf curing.
