[0030] Please refer to Figures 1-4 , a mobile tobacco leaf baking rack, including a top plate 1, two clamping assemblies 2 for clamping tobacco leaves are symmetrically arranged below the top plate 1, a driving assembly 3 for driving the clamping assemblies 2 to reciprocate is arranged on the top of the top plate 1, and a lifting and moving device 4 for driving the top plate 1 to lift and move is arranged below the top plate 1;

[0031] The lifting and moving device 4 includes a moving assembly 41, a support column 42 is fixedly connected to the top of the moving assembly 41, an inner support rod 43 is slidably connected in the support column 42, and a lifting rack 44 is embedded on one outer side wall of the inner support rod 43 along its height direction. A housing 47 is arranged on the outer side wall of the support column 42. A worm 48 is rotatably arranged in the housing 47. One end of the worm 48 penetrates through the housing 47 and is fixedly connected to a turning handle 49. A worm gear 50 is also rotatably arranged in the housing 47, and the worm gear 50 is meshed with the worm 48. The worm gear 50 passes through the housing 47 and is meshed with the lifting rack 44.

[0032] With such a design, firstly, the two clamping assemblies 2 symmetrically arranged below the top plate 1 can stably clamp the tobacco leaves, ensuring that the tobacco leaves maintain a good shape during the baking process, which is beneficial to uniform heating and improves the baking quality.

[0033] Secondly, the driving assembly 3 drives the clamping assemblies 2 to reciprocate, which is convenient for adjusting the position of the tobacco leaves, enabling the tobacco leaves to fully contact the heat source, and further improving the uniformity and effect of baking.

[0034] Thirdly, the moving assembly 41 enables the entire baking rack to be conveniently moved to different positions, adapting to different working environments and requirements, and improving the flexibility and practicality of the equipment.

[0035] Fourthly, the combined design of the support column 42 and the inner support rod 43 drives the worm 48 by turning the handle 49, and the worm 48 drives the worm wheel 50 to rotate. The worm wheel 50 engages with the lifting rack 44 to realize the lifting and lowering of the inner support rod 43, thereby adjusting the height of the top plate 1 according to actual needs, so that the height of the clamping assembly 2 can adapt to workers of different heights for hanging materials.

[0036] The inner support rod 43 is symmetrically provided with limit blocks 45 on the outer side walls on both sides of the lifting rack 44. Limit grooves 46 are provided on the inner walls on both sides of the support column 42 along the height direction thereof, and the limit blocks 45 are slidably arranged in the limit grooves 46.

[0037] With this design, the setting of the limit block 45 and the limit slot 46 ensures the stability and linearity of the inner support rod 43 during the lifting process, prevents deviation or shaking, and ensures the safe operation of the equipment.

[0038] A rotating rod 51 is fixedly sleeved in the worm gear 50 , and both ends of the rotating rod 51 are rotatably connected to the housing 47 respectively.

[0039] The driving assembly 3 includes a bracket fixedly mounted on the top of the top plate 1 , a motor 31 is fixedly mounted on the top of the bracket, and a power output end of the motor 31 is transmission-connected to a rotating shaft 32 .

[0040] A gear 33 is fixedly sleeved on the rotating shaft 32, and two rack plates 34 are symmetrically meshed and connected on both sides of the gear 33. A connecting plate 35 is fixedly connected to the side of the two rack plates 34 facing away from each other, and the connecting plate 35 is transmission-connected to the clamping assembly 2.

[0041] A sliding groove 36 is provided at the top of the top plate 1 at a position corresponding to the rack plate 34 and symmetrically extending along the length thereof. A slider 37 is slidably connected in the sliding groove 36 , and the slider 37 is fixedly connected to the corresponding rack plate 34 .

[0042] When in use, first start the motor 31, and the power output end of the motor 31 drives the gear 33 to rotate through the rotating shaft 32. Since the gear 33 is engaged with the two rack plates 34, and under the guidance of the slider 37 and the slide groove 36, the rotation of the gear 33 drives the two rack plates 34 to make relative or opposite linear motions, and the movement of the rack plate 34 drives the clamping assembly 2 to move, thereby facilitating the adjustment of the position of the tobacco leaves, so that the tobacco leaves can fully contact the heat source, and further improve the uniformity and effect of baking.

[0043] Two movable grooves 6 are formed through the top of the top plate 1 , and the two movable grooves 6 are symmetrically arranged outside the two sliding grooves 36 . The movable grooves 6 have the same structure as the sliding grooves 36 and are distributed parallel to each other. The clamping assembly 2 is slidably arranged in the movable grooves 6 .

[0044] The clamping assembly 2 includes a mounting plate 21 slidably disposed in the movable groove 6 , the top of the mounting plate 21 is fixedly connected to the corresponding connecting plate 35 , and the bottom of the mounting plate 21 passes through the movable groove 6 and extends to below the top plate 1 .

[0045] Fixed blocks 22 are symmetrically provided on both sides of the mounting plate 21 near its bottom. Slide rods 23 are vertically slidably sleeved in the fixed blocks 22. One end of the slide rod 23 is fixedly connected to a limit plate 24, and the other end is fixedly connected to a pressure plate 25.

[0046] The slide bar 23 is sleeved with a spring 26 , and both ends of the spring 26 are fixedly connected to the pressing plate 25 and the fixing block 22 respectively.

[0047] When tobacco leaves need to be clamped, the limit plate 24 is first pushed toward the fixed block 22. The limit plate 24 drives the slide bar 23 to move. At this time, the slide bar 23 pushes the pressure plate 25 outward. At this time, the spring 26 is in a stretched state. Then the tobacco leaves are placed between the mounting plate 21 and the pressure plate 25. Then the slide bar 23 is released. The pressure plate 25 is pulled back under the rebound of the spring 26 and the tobacco leaves are clamped.

[0048] With this design, first, the clamping space is opened by pushing the slide rod 23, and the tobacco leaves are automatically clamped when released after being placed, making the tobacco leaf clamping operation convenient and efficient; secondly, the spring 26 is used to control the movement of the pressure plate 25 to adapt to tobacco leaves of different thicknesses; thirdly, the spring 26 rebounds to ensure sufficient clamping force, and it is not easy to loosen during processing and transportation; finally, it can also avoid damaging the tobacco leaves, and the spring 26 buffers to avoid excessive instantaneous pressure, thereby protecting the integrity and quality of the tobacco leaves.

[0049] The moving assembly 41 includes a moving frame 411 fixedly mounted on the bottom of a support column 42 , and universal wheels 412 with brake devices are provided at the four corners of the bottom of the moving frame 411 .

[0050] First of all, it allows the equipment to move freely in different directions, adapt to various work scenarios, improve maneuverability, make handling and multi-tasking operations more convenient, and save manpower and time.

[0051] Secondly, the operator can push it easily, and one person can move the equipment, which improves work efficiency. The brake device can be fixed after the equipment is in place to ensure safe and stable operation.

[0052] Furthermore, it is suitable for different ground conditions to ensure smooth movement of the equipment, and the brake device can effectively prevent sliding due to uneven or sloped ground.

[0053] Finally, it can improve work efficiency. The equipment can be quickly moved to another location, reducing idle time and improving utilization. It can also be moved directly to the workpiece for operation, saving time and labor costs.

[0054] For specific use, first move the tobacco leaf baking rack to the required position through the universal wheels 412. After moving to the appropriate position, lock the universal wheels 412.

[0055] Subsequently, according to the height of the staff, adjust the height of the clamping assembly 2 of the tobacco leaf baking rack. At this time, manually rotate the handle 49 outside the housing 47. The rotation of the handle 49 drives the worm 48 to rotate. Since the worm 48 is meshed with the worm gear 50, when the worm 48 rotates, it will drive the worm gear 50 to rotate. When the worm gear 50 rotates, it will drive the engaged lifting rack 44 to move up and down. Under the guiding action of the limit block 45 and the limit groove 46, when the lifting rack 44 moves up and down, it will drive the inner support rod 43 to move smoothly up and down in the support column 42, driving the up and down movement of the top plate 1. Thus, the top plate 1 drives the clamping assembly 2 to a suitable height for staff of different heights.

[0056] When the clamping assembly 2 is adjusted to a suitable height, then hang the tobacco leaves. At this time, first push the limit plate 24 in the direction of the fixed block 22. At this time, the slide rod 23 will push the pressure plate 25 outwards. At this time, the spring 26 is in a stretched state. Then place the tobacco leaves between the mounting plate 21 and the pressure plate 25. Subsequently, release the slide rod 23. Under the rebound of the spring 26, the pressure plate 25 will be pulled back and the tobacco leaves will be clamped and fixed on the mounting plate 21.

[0057] After the placement is completed, first start the motor 31. The power output end of the motor 31 drives the gear 33 to rotate through the rotating shaft 32. Since the gear 33 is meshed with the two rack plates 34, and under the guiding action of the slider 37 and the chute 36, the rotation of the gear 33 drives the two rack plates 34 to perform relative or opposite linear motions. The movement of the rack plates 34 drives the clamping assembly 2 to move, thus facilitating the adjustment of the position of the tobacco leaves, enabling the tobacco leaves to fully contact the heat source, and further improving the uniformity and effect of baking.

[0058] For those of ordinary skill in the art, according to the teachings of the present utility model, without departing from the principles and spirit of the present utility model, the changes, modifications, substitutions and variations made to the embodiments still fall within the protection scope of the present utility model.
