Description

Technical Field

[0001] This utility model belongs to the field of tobacco drying technology, and in particular relates to a tobacco drying rack. Background Technology

[0002] Tobacco drying refers to the process of removing moisture from freshly picked tobacco leaves using certain methods to make them suitable for storage and processing. Tobacco leaves contain a high moisture content after picking and typically need to be dried to a certain moisture content to achieve the desired quality. In summary, the existing technology has the following problems: Tobacco drying racks are multi-layered tobacco drying equipment that dries tobacco leaves through natural ventilation or drying equipment. During use, the tobacco leaves are first hung on hanging rods, and then the hanging rods are arranged to suspend the leaves on the racks. Because the racks are square, after sequential arrangement, except for the leaves at both ends, the other tobacco leaves are in the middle and are obstructed, easily causing the leaves at both ends to dry before the middle leaves, resulting in uneven drying. However, existing tobacco drying racks lack components for more uniform drying of the tobacco leaves. Therefore, a new tobacco drying rack is proposed to solve the above problems. Utility Model Content

[0003] To address the problems of existing technologies, this utility model provides a tobacco leaf drying rack that enables more uniform drying of tobacco leaves. It solves the problem that existing tobacco leaf drying racks are multi-layered drying devices that dry tobacco leaves through natural ventilation or drying equipment. In use, tobacco leaves are first hung on hanging rods, and then the hanging rods are arranged to suspend the leaves on the rack. Because the rack is a square frame, after sequential arrangement, except for the leaves at both ends, the other tobacco leaves are in the middle and are obstructed, easily causing the leaves at both ends to dry before the middle leaves, resulting in uneven drying. However, existing tobacco leaf drying racks lack components for more uniform drying.

[0004] This utility model is implemented as follows: a tobacco leaf drying rack includes a column and a first rotating frame. The first rotating frame is movably connected to the surface of the column via a rotating shaft. A second rotating frame is movably connected to the surface of the column via a rotating shaft. Both the first and second rotating frames have several mounting slots at their tops. A suspension rod is movably connected to the inner cavity of each mounting slot. The top of the suspension rod passes through the mounting slot and extends to the outside of the inner cavity of the mounting slot. Several hanging rings are provided at the bottom of the suspension rod. A rotary motor is installed inside the inner cavity of the column. The output end of the rotary motor is fixedly connected to the top of the first rotating frame. A device slot is provided inside the suspension rod. A control frame is movably connected to the inner cavity of the device slot. The top of the control frame passes through the device slot and extends to the outside of the inner cavity of the device slot. A limit device is provided inside the device slot.

[0005] As a preferred embodiment of this utility model, the limiting device includes two limiting blocks. The opposite sides of the two limiting blocks both penetrate the device groove and extend to the outer side of the inner cavity of the device groove. A movable locking block is fixedly connected to the side of the limiting block near the column, and a spring is fixedly connected to the opposite side of the two limiting blocks. By setting the limiting device, when the suspension rod moves into the inner cavity of the mounting groove, the limiting device has a limiting effect on the position of the suspension rod.

[0006] As a preferred embodiment of this utility model, a pressing rod is fixedly connected to the bottom of the control frame, and a pressing hole for cooperating with the pressing rod is opened on the surface of the limiting block. The surface of the pressing rod is movably connected to the inner cavity of the pressing hole. By setting the pressing rod and the pressing hole, when the control frame moves, it will drive the pressing rod to move. When the pressing rod moves, it can generate a pressing force on the pressing hole. The pressing hole subjected to the pressing force can drive the two limiting blocks to move.

[0007] As a preferred embodiment of this utility model, the inner cavity of the device groove is fixedly connected to a movable frame that works in conjunction with the movable block. The surface of the movable block is movably connected to the inner cavity of the movable frame. By setting the movable block and the movable frame, when the limiting block moves, the movable block can be driven to move along the inner cavity of the movable frame. The cooperation between the movable block and the movable frame has a limiting effect on the movement position of the limiting block.

[0008] As a preferred embodiment of this utility model, a limiting hole is formed on the surface of the extrusion rod, and a limiting block that cooperates with the limiting hole is fixedly connected to the inner cavity of the device groove. The surface of the limiting block is movably connected to the inner cavity of the limiting hole. By setting the limiting hole and the limiting block, when the extrusion rod moves, it can drive the limiting hole to move along the surface of the limiting block. The cooperation of the limiting hole and the limiting block has a limiting effect on the movement position of the extrusion rod.

[0009] As a preferred embodiment of this utility model, the inner cavity of the mounting groove is provided with two limiting grooves that cooperate with the limiting block. The surface of the limiting block is in contact with the inner cavity of the limiting groove. By setting the limiting groove, when the suspension rod moves to the inner cavity of the mounting groove, the control block is released, and the restoring force generated by the spring returning to its shape will drive the limiting block to be locked into the inner cavity of the limiting groove. The cooperation between the limiting block and the limiting groove has a limiting effect on the position of the suspension rod.

[0010] As a preferred embodiment of this utility model, the bottom of the first rotating frame is fixedly connected to two plug rods, and the top of the second rotating frame is provided with two plug slots that cooperate with the plug rods. The surface of the plug rods contacts the inner cavity of the plug slots. By setting the plug rods and plug slots, when the first rotating frame rotates, it will drive the plug rods to rotate along the inner cavity of the plug slots. The cooperation of the plug rods and plug slots can drive the second rotating frame to rotate along the surface of the column via the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing tobacco drying racks, which are multi-layered tobacco drying equipment that dries tobacco leaves through natural ventilation or drying equipment, by setting up a limiting device, limiting block, moving block, spring and limiting groove in combination. In use, the tobacco leaves are first hung on the hanging rods, and then the hanging rods are arranged to hang on the rack. Because the overall shape of the rack is a square frame, after the tobacco leaves are arranged in sequence, except for the tobacco leaves at both ends, the other tobacco leaves are in the middle and are blocked. This makes it easy for the tobacco leaves at both ends to be dried before the tobacco leaves in the middle, resulting in uneven drying. However, existing tobacco drying racks do not have components that can make the tobacco leaves dry more evenly.

[0013] 2. This utility model, by setting a limiting device, will cause the moving block to move along the inner cavity of the moving frame when the limiting block moves. The force generated when the limiting block moves will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will cause the limiting block to be locked into the inner cavity of the limiting groove. The limiting device has a limiting effect on the position of the suspension rod. Attached Figure Description

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a tobacco leaf drying rack, including a column 1 and a first rotating frame 2. The first rotating frame 2 is movably connected to the surface of the column 1 via a rotating shaft. A second rotating frame 3 is movably connected to the surface of the column 1 via a rotating shaft. The top of both the first rotating frame 2 and the second rotating frame 3 are provided with a plurality of mounting slots 4. A suspension rod 5 is movably connected to the inner cavity of the mounting slot 4. The top of the suspension rod 5 passes through the mounting slot 4 and extends to the outside of the inner cavity of the mounting slot 4. A plurality of hanging rings 6 are provided at the bottom of the suspension rod 5. A rotary motor 7 is provided in the inner cavity of the column 1. The output end of the rotary motor 7 is fixedly connected to the top of the first rotating frame 2. A device slot 8 is provided inside the suspension rod 5. A control frame 9 is movably connected to the inner cavity of the device slot 8. The top of the control frame 9 passes through the device slot 8 and extends to the outside of the inner cavity of the device slot 8. A limit device 10 is provided inside the device slot 8.

[0022] refer to Figure 4 The limiting device 10 includes two limiting blocks 1001. The opposite sides of the two limiting blocks 1001 pass through the device groove 8 and extend to the outside of the inner cavity of the device groove 8. A movable locking block 1002 is fixedly connected to the side of the limiting block 1001 near the column 1, and a spring 1003 is fixedly connected to the opposite side of the two limiting blocks 1001.

[0023] The above solution is adopted: by setting a limiting device 10, when the suspension rod 5 moves into the inner cavity of the mounting groove 4, the limiting device 10 has a limiting effect on the position of the suspension rod 5.

[0024] refer to Figure 4 A pressing rod 11 is fixedly connected to the bottom of the control frame 9. A pressing hole 12 is opened on the surface of the limiting block 1001 to cooperate with the pressing rod 11. The surface of the pressing rod 11 is movably connected to the inner cavity of the pressing hole 12.

[0025] Using the above scheme: By setting the extrusion rod 11 and the extrusion hole 12, when the control frame 9 moves, it will drive the extrusion rod 11 to move. When the extrusion rod 11 moves, it can generate extrusion force on the extrusion hole 12. The extrusion hole 12 subjected to extrusion force can drive the two limit blocks 1001 to move.

[0026] refer to Figure 4 The inner cavity of the device slot 8 is fixedly connected to a movable frame 13 that works in conjunction with the movable block 1002, and the surface of the movable block 1002 is movably connected to the inner cavity of the movable frame 13.

[0027] The above scheme is adopted: by setting the movable block 1002 and the movable frame 13, when the limiting block 1001 moves, it can drive the movable block 1002 to move along the inner cavity of the movable frame 13. The cooperative use of the movable block 1002 and the movable frame 13 has a limiting effect on the movement position of the limiting block 1001.

[0028] refer to Figure 4 The surface of the extrusion rod 11 is provided with a limiting hole 14, and the inner cavity of the device groove 8 is fixedly connected with a limiting block 15 that cooperates with the limiting hole 14. The surface of the limiting block 15 is movably connected to the inner cavity of the limiting hole 14.

[0029] The above solution is adopted: by setting the limiting hole 14 and the limiting block 15, when the extrusion rod 11 moves, it can drive the limiting hole 14 to move along the surface of the limiting block 15. The cooperation of the limiting hole 14 and the limiting block 15 has a limiting effect on the movement position of the extrusion rod 11.

[0030] refer to Figure 2 The inner cavity of the mounting groove 4 has two limiting grooves 16 that cooperate with the limiting block 1001, and the surface of the limiting block 1001 contacts the inner cavity of the limiting groove 16.

[0031] The above solution is adopted: by setting the limiting groove 16, when the suspension rod 5 moves into the inner cavity of the mounting groove 4, the control block is released, and the restoring force generated by the spring 1003 returning to its shape will drive the limiting block 1001 to be inserted into the inner cavity of the limiting groove 16. The cooperation between the limiting block 1001 and the limiting groove 16 has a limiting effect on the position of the suspension rod 5.

[0032] refer to Figure 3 The bottom of the first rotating frame 2 is fixedly connected with two plug rods 17, and the top of the second rotating frame 3 has two plug slots 18 that cooperate with the plug rods 17. The surface of the plug rods 17 contacts the inner cavity of the plug slots 18.

[0033] The above solution is adopted: by setting the plug rod 17 and the plug slot 18, when the first rotating frame 2 rotates, it will drive the plug rod 17 to rotate along the inner cavity of the plug slot 18. The cooperation of the plug rod 17 and the plug slot 18 can drive the second rotating frame 3 to rotate along the surface of the column 1 through the rotating shaft.

[0034] The working principle of this utility model:

[0035] When using the tobacco drying rack, to ensure more even drying of the tobacco leaves, the user first presses the control frame 9 at the bottom. As the control frame 9 moves, it causes the pressing rod 11 to move downwards. This movement of the pressing rod 11 causes the limiting hole 14 to move along the surface of the limiting block 15. The pressing rod 11 exerts pressure on the pressing hole 12, causing the two limiting blocks 1001 to move closer together. This movement of the limiting blocks 1001 causes the moving block 1002 to move along the inner cavity of the moving frame 13. The force generated by the movement of the limiting blocks 1001 causes the spring 1003 to elastically deform. Once the limiting blocks 1001 have completely moved into the inner cavity of the device slot 8, the suspension rod 5 is moved into the inner cavity of the mounting slot 4. Then, the control frame 9 is released, and the spring 1003 returns to its original shape. The restoring force generated by the shape will cause the limiting block 1001 to be inserted into the inner cavity of the limiting groove 16. The cooperation between the limiting block 1001 and the limiting groove 16 has a limiting effect on the position of the suspension rod 5. After the required number of suspension rods 5 are installed, the tobacco leaves can be suspended on the hanging ring 6. Then, the rotary motor 7 is started. The rotary motor 7 will drive the first rotating frame 2 to rotate along the surface of the column 1 through the rotating shaft. When the first rotating frame 2 rotates, it will drive the insertion rod 17 to rotate. The insertion rod 17 will generate a rotational force on the insertion groove 18 and drive the second rotating frame 3 to rotate along the surface of the column 1 through the rotating shaft. The first rotating frame 2 and the second rotating frame 3 will drive the tobacco leaves to rotate, so that the tobacco leaves suspended in different positions can be dried by the drying equipment, avoiding the phenomenon that the tobacco leaves are piled together and cannot be dried. At this time, the placement rack used for tobacco drying will dry the tobacco leaves more evenly.

[0036] In summary, this tobacco drying rack, through the coordinated use of the limiting device 10, limiting block 1001, moving block 1002, spring 1003, and limiting groove 16, solves the problem of existing tobacco drying racks being multi-layered tobacco drying equipment that dries tobacco leaves through natural ventilation or drying equipment. In use, tobacco leaves are first hung on hanging rods, and then the hanging rods are arranged to suspend the tobacco leaves on the rack. Because the overall shape of the rack is a square frame, after sequential arrangement, except for the tobacco leaves at both ends, the other tobacco leaves are in the middle and are obstructed, easily causing the tobacco leaves at both ends to dry before the middle tobacco leaves, resulting in uneven drying. However, existing tobacco drying racks lack components for more uniform drying of tobacco leaves.
