A first square neck sleeve is installed in one of the fixing sleeves through bearing cooperation, and a second square neck sleeve is slidably connected in the second square neck sleeve. A spring is also sleeved on the second square neck sleeve.

[0008] As a further technical solution of the present invention, a sprocket is fitted to the outer end of each second square neck sleeve, and multiple sprockets are connected by a toothed chain drive. Multiple tension sprockets are also provided on both sides of the toothed chain to ensure that the sprocket wrap angle between the toothed chain and each sprocket is not less than 120 degrees. Any one of the multiple sprockets is also coaxially equipped with a gear, which meshes with a toothed plate; the bottom of the toothed plate is fixed to the cylinder rod of the push cylinder, and the push cylinder is fixed on a bracket for mounting the tension sprocket.

[0009] As a further technical solution of the present invention, the tobacco leaf fixing frame includes a tobacco leaf frame, and square necks are integrally installed at both ends of the tobacco leaf frame; multiple metal wires are arranged in a crisscross pattern on the bottom side of the tobacco leaf frame.

[0010] As a further technical solution of the present invention, each material frame assembly is provided with two tobacco leaf fixing frames, and gaps are reserved between the two tobacco leaf fixing frames and between the tobacco leaf fixing frames and the material frame assembly, so that the tobacco leaf fixing frames can rotate 180 degrees in the material frame assembly.

[0011] As a further technical solution of the present invention, it also includes a flipping device disposed at one end of the first frame conveyor, and a laser cutting device disposed on the rear side of the flipping device; a second frame conveyor is disposed on the side of the flipping device away from the laser cutting device; and a controller is disposed on one side of the second frame conveyor.

[0012] As a further technical solution of the present invention, the tilting device includes a frame body, on which a transmission unit is fixedly installed. A tilting arm is mounted on the output shaft of the transmission unit via a coupling. The transmission shaft portion of the tilting arm is mounted on the frame body via a bearing seat. The tilting arm is U-shaped, and multiple pressing cylinders are fixed on both sides of the tilting arm.

Detailed Implementation

[0031] 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.

[0032] Please see Figure 1 In this embodiment of the invention, an intelligent cigar tobacco fermentation warehouse includes a tobacco processing room 100, which has a tobacco rehumidification room, a moisture balance room, a fermentation room, a sorting and grading room, a controlled temperature room, and a finished product warehouse. Cigar tobacco fermentation is a core step in enhancing the aroma, reducing irritation, and stabilizing the quality of cigar tobacco leaves. It involves three stages: primary fermentation (field fermentation), secondary fermentation (warehouse fermentation), and aging fermentation. The process, control parameters, and environmental requirements for each stage differ significantly.

[0033] Primary fermentation: basic alkali reduction and moisture balance.

[0034] Process objectives: To remove the green and unpleasant odors from freshly harvested tobacco leaves, reduce nicotine (alkali reduction rate of 15%-20%), balance leaf moisture, and lay the foundation for subsequent fermentation.

[0035] Secondary fermentation: aroma transformation and quality shaping.

[0036] Through the metabolism of microorganisms (mainly yeast and lactic acid bacteria), the proteins and pectins in tobacco leaves are broken down into aromatic substances (such as esters and aldehydes), reducing the irritation by 40%-50% and initially forming the aroma characteristics.

[0037] Aging and fermentation: aroma blending and stability enhancement.

[0038] Further degradation of residual organic acids and alkaloids results in a richer aroma and a stable tobacco leaf moisture content of 12%-14%, facilitating subsequent rolling.

[0039] The fermentation chamber in this invention is designed for the re-fermentation of tobacco leaves, and a set of tobacco leaf fermentation and cutting equipment is installed in the fermentation chamber; During the mid-stage (15-20 days) of tobacco re-fermentation, the tobacco leaves need to be cut; the leaves are separated into "tobacco veins" and "tobacco sheets" according to the direction of the leaf veins. The tobacco sheets continue to ferment separately (the tobacco veins need to be fermented separately, which takes longer); the cycle is 30-60 days, and some high-end cigar tobacco leaves can be extended to 90 days.

[0040] Please refer to the attached diagram. Figure 2-6 In this invention, the tobacco fermentation and cutting equipment includes multiple tobacco fermentation mechanisms 2 arranged in parallel, and a first frame conveyor 1 is provided in front of the multiple tobacco fermentation mechanisms 2; the first frame conveyor 1 is provided with a sliding track 4 on the side away from the tobacco fermentation mechanism 2, and a loading and unloading robot 3 is installed on the sliding track 4. The tobacco fermentation mechanism 2 includes a storage rack 21, on which multiple material frame assemblies 22 are arranged; a heat-concentrating cover 23 is installed on the top of the storage rack 21; a disc heat pipe 25 is provided inside the heat-concentrating cover 23; a fan 24 is fixedly installed on the top of the heat-concentrating cover 23; and an energy-saving lamp 26 is also installed on the outer side of the top of the storage rack 21.

[0041] More specifically, the tobacco leaf fixing frame 9 includes a tobacco leaf frame 91, which has square necks 93 integrally installed at both ends; the bottom side of the tobacco leaf frame 91 is provided with multiple metal wires 92 in a crisscross pattern. The inner side of the upper end of the tobacco frame 91 is fitted with a snap-fit ​​frame, and the snap-fit ​​frame is also provided with multiple metal wires 92 in a crisscross pattern.

[0042] By adopting the above technical solution, when re-fermenting tobacco leaves, the primary fermented tobacco leaves are first bundled into small bundles, each bundle containing 15-20 tobacco leaves with the leaf tips facing inward and the leaf stalks facing outward; at least five bundles of tobacco leaves are stacked together and placed in the tobacco leaf fixing frame 9, and then the tobacco leaves are pressed and fixed using the clamping frame.

[0043] The tobacco leaf fixing frame 9, which has been pressed with tobacco leaves, is transported to the front of the tobacco fermentation mechanism 2 by the first frame conveyor 1. The loading and unloading robot 3 slides along the sliding track 4 and places the tobacco leaf fixing frame 9 into the designated material frame assembly 22 for fermentation.

[0044] It should be noted that the disc heat pipe 25 is arranged in an S-shape in the heating cover 23, and the disc heat pipe 25 is also connected to the steam generator; after setting the steam temperature of the steam generator, the steam generator will transfer steam to the disc heat pipe 25, and the heat generated by the disc heat pipe 25 will be dissipated into the heating cover 23. The fan 24 blows the heating cover 23 downward, so that the hot air covers each layer of the material frame assembly 22, ensuring that the temperature of the tobacco leaves on each layer of the material frame assembly 22 is suitable.

[0045] Please see the appendix Figure 7-10In this embodiment, the feed frame assembly 22 is used to place the tobacco leaf fixing frame 9; the feed frame assembly 22 includes a rectangular feed frame 221, and the two ends of the feed frame 221 are integrally provided with fixing sleeves 224. A first square neck sleeve 222 is installed in one of the fixing sleeves 224 through bearing cooperation, and a second square neck sleeve 223 is slidably connected in the second square neck sleeve 223. A spring 225 is also sleeved on the second square neck sleeve 223.

[0046] By adopting the above technical solution, when the tobacco frame 91 is placed into the material frame assembly 22, the mechanical arm of the loading and unloading robot 3 is first used to clamp the tobacco fixing frame 9. Then, the square neck 93 at one end of the tobacco frame 91 is inserted into the second square neck sleeve 223, and the second square neck sleeve 223 is forced to compress the spring 225 and move outward. Subsequently, the square neck 93 at the other end of the tobacco frame 91 is inserted into the first square neck sleeve 222, thereby realizing the overall placement of the tobacco fixing frame 9. The structure is simple, the operation is convenient, and the loading and unloading efficiency during the tobacco fermentation process is improved.

[0047] Please see the appendix Figure 9 and Figure 13 In this embodiment, a sprocket 27 is fitted to the outer end of each second square neck sleeve 223. Multiple sprockets 27 are connected by a toothed chain 28. Multiple tension sprockets 29 are also provided on both sides of the toothed chain 28 to ensure that the sprocket wrap angle between the toothed chain 28 and each sprocket 27 is not less than 120 degrees. Any one of the multiple sprockets 27 is also coaxially provided with a gear 210, which meshes with a toothed plate 211; the bottom of the toothed plate 211 is fixed to the cylinder rod of the push cylinder 212, and the push cylinder 212 is fixed on a bracket for mounting the tension sprocket 29.

[0048] By adopting the above technical solution, during the tobacco fermentation process, the cylinder rod of the cylinder 212 is pushed to extend and retract at irregular intervals. Under the continuous movement of the toothed plate 211, the gear 210 and the material frame assembly 22 are driven to rotate. Therefore, the hot air blown out by the fan 24 will adhere to each tobacco leaf fixing frame 9, so that the tobacco leaves in each tobacco leaf fixing frame 9 can ferment at a suitable temperature.

[0049] Each feed frame assembly 22 is provided with two tobacco leaf fixing frames 9, and gaps are reserved between the two tobacco leaf fixing frames 9 and between the tobacco leaf fixing frames 9 and the feed frame assembly 22 so that the tobacco leaf fixing frames 9 can rotate 180 degrees in the feed frame assembly 22.

[0050] Please see the appendix Figure 2-4It should be noted that the present invention also includes a flipping device 5 disposed at one end of the first frame-type conveyor 1, and a laser cutting device 6 disposed on the rear side of the flipping device 5; a second frame-type conveyor 8 disposed on the side of the flipping device 5 away from the laser cutting device 6; and a controller 7 disposed on one side of the second frame-type conveyor 8.

[0051] More specifically, the tilting device 5 includes a frame body 51, on which a transmission unit 52 is fixedly mounted. A tilting arm 53 is mounted on the output shaft of the transmission unit 52 via a coupling. The transmission shaft portion of the tilting arm 53 is mounted on the frame body 51 via a bearing seat. The tilting arm 53 is U-shaped, and multiple pressing cylinders 54 are fixed on both sides of the tilting arm 53. The cylinder rod end of the pressing cylinder 54 is movably connected to a pressing arm 55 via a rotating shaft. A hinge piece 56 is movably connected to the bottom side of the pressing arm 55 via a rotating shaft, and the hinge piece 56 is movably connected to the mounting base on the bottom side via a rotating shaft.

[0052] By adopting the above technical solution, when the tobacco leaves in each tobacco leaf fixing frame 9 need to be turned over, the loading and unloading robot 3 takes the tobacco leaf fixing frame 9 out of the material frame assembly 22 and places it on the flipping arm 53. The cylinder rod of the pressing cylinder 54 extends, so that the pressing arm 55 presses the outer frame of the tobacco leaf fixing frame 9 tightly. Then the loading and unloading robot 3 removes the clamping frame, turns over the tobacco leaves inside, and re-clamps it, and then puts it into the material frame assembly 22 to continue fermentation.

[0053] Additionally, please see the appendix. Figure 2-3 and Figure 11-12 The flipping device 5 can also be used in conjunction with the laser cutting device 6; the laser cutting device 6 includes a longitudinal moving mechanism 61, on which a transverse driving module 62 is mounted; a vertical driving module 63 is mounted on one side of the transverse driving module 62; and a laser cutter 64 is mounted on the vertical driving module 63.

[0054] During the mid-stage (15-20 days) of tobacco re-fermentation, the tobacco leaves need to be cut; the leaves are separated into "tobacco veins" and "tobacco flakes" according to the direction of the leaf veins.

[0055] By adopting the above technical solution, the loading and unloading robot 3 takes the tobacco leaf fixing frame 9 out of the material frame assembly 22 and then places it on the flipping arm 53. The cylinder rod of the pressing cylinder 54 extends, so that the pressing arm 55 presses the outer frame of the tobacco leaf fixing frame 9. With the cooperation of the longitudinal moving mechanism 61, the transverse driving module 62, the vertical driving module 63 and the laser cutter 64, the tobacco leaf is cut, so that the "tobacco ribs" and "tobacco sheets" are separated.

[0056] It should be noted that during the mid-stage of tobacco re-fermentation, the ambient temperature should be stabilized at 20-25℃ and the relative humidity should be maintained at 50%-60%. If processing very thin or highly flammable tobacco leaves (such as flue-cured tobacco), a small amount of flame retardant (such as 0.5% ammonium dihydrogen phosphate solution) can be sprayed on the surface of the tobacco leaves before cutting.

[0057] CO2 laser (wavelength 10.6μm) is preferred because its energy is more easily absorbed by organic matter (tobacco fiber), and compared with fiber laser (wavelength 1.06μm), it causes less thermal damage to tobacco leaves (the width of the heat-affected zone can be controlled within 0.1mm).

[0058] Laser cutting can also reduce problems such as tobacco stem breakage and tobacco leaf damage, making it suitable for the precision requirements of tobacco processing.

[0059] After the tobacco leaves are cut and separated, the loading and unloading robot 3 places the tobacco leaf fixing frame 9 onto the second frame conveyor 8 and transports it to the grading and sorting room for sorting. The tobacco leaves continue to ferment, while the tobacco fibers need to be fermented separately.

[0060] The working principle of this invention is as follows: When re-fermenting tobacco leaves, the primary fermented tobacco leaves are first bundled into small bundles, each bundle containing 15-20 tobacco leaves with the leaf tips facing inward and the leaf stalks facing outward; at least five bundles of tobacco leaves are stacked together and placed in the tobacco leaf fixing frame 9, and then the tobacco leaves are pressed and fixed using the clamping frame.

[0061] The tobacco leaf fixing frame 9, with the pressed tobacco leaves, is transported to the front of the tobacco fermentation mechanism 2 via the first frame conveyor 1. The loading and unloading robot 3 slides along the sliding track 4 and places the tobacco leaf fixing frame 9 into the designated material frame assembly 22 for fermentation. The disc heat pipe 25 is arranged in an S-shape in the heating cover 23 and is also connected to the steam generator. The steam temperature of the steam generator is set, and the steam generator will transfer steam to the disc heat pipe 25. The heat generated by the disc heat pipe 25 will be dissipated into the heating cover 23. The fan 24 blows the heating cover 23 downward, so that the hot air covers each layer of the material frame assembly 22, ensuring that the temperature of the tobacco leaves on each layer of the material frame assembly 22 is suitable.

[0062] When placing the tobacco frame 91 into the material frame assembly 22, the mechanical arm of the loading and unloading robot 3 first clamps the tobacco fixing frame 9, then inserts the square neck 93 at one end of the tobacco frame 91 into the second square neck sleeve 223, and forces the second square neck sleeve 223 to compress the spring 225 and move it outward; then the square neck 93 at the other end of the tobacco frame 91 is inserted into the first square neck sleeve 222, thus realizing the overall placement of the tobacco fixing frame 9. The structure is simple, the operation is convenient, and the loading and unloading efficiency during the tobacco fermentation process is improved.

[0063] When the tobacco leaves in each tobacco leaf fixing frame 9 need to be turned over, the loading and unloading robot 3 removes the tobacco leaf fixing frame 9 from the material frame assembly 22 and places it on the flipping arm 53. The cylinder rod of the pressing cylinder 54 extends, so that the pressing arm 55 presses the outer frame of the tobacco leaf fixing frame 9 tightly. Then the loading and unloading robot 3 removes the clamping frame, turns over the tobacco leaves inside, and re-clamps it, and then puts it back into the material frame assembly 22 to continue fermentation. In the middle stage of tobacco leaf re-fermentation, 15-20 days, the tobacco leaves need to be cut. The leaves are separated into "tobacco veins" and "tobacco flakes" according to the direction of the leaf veins.

[0064] By adopting the above technical solution, the loading and unloading robot 3 removes the tobacco leaf fixing frame 9 from the material frame assembly 22 and places it on the tilting arm 53. The cylinder rod of the pressing cylinder 54 extends, causing the pressing arm 55 to press the outer frame of the tobacco leaf fixing frame 9. With the cooperation of the longitudinal moving mechanism 61, the transverse drive module 62, the vertical drive module 63, and the laser cutter 64, the tobacco leaves are cut, separating the "tobacco ribs" from the "tobacco sheets". After the tobacco leaves are cut and separated, the loading and unloading robot 3 places the tobacco leaf fixing frame 9 on the second frame conveyor 8 and transports it to the grading and sorting room for sorting. The tobacco sheets continue to ferment, while the tobacco ribs need to be fermented separately.
