[0038] Referring to Figure 1 and Figure 2 The embodiment provides a tobacco roasting device, which comprises:

[0039] The roasting box 100 is internally provided with a containing cavity, the containing cavity is fixedly connected with a waste liquid tank 400 at the bottom, and the waste liquid tank 400 is detachably connected with a sealing plug 401 at the bottom;

[0040] The clamping mechanism 200 is arranged in the containing cavity, and the clamping mechanism 200 comprises a transmission assembly and a clamping assembly;

[0041] The spraying mechanism is arranged between the clamping device and the waste liquid tank 400;

[0042] The roasting mechanism is arranged on the outer side of the roasting box 100 and is used for heating air entering the roasting box 100.

[0043] Specifically, the roasting process comprises:

[0044] Firstly, the transmission assembly of the clamping mechanism 200 is operated to drive the clamping assembly to act, so as to stably clamp the article to be roasted and place the article in a suitable position, so that the article is located within the action range of the spraying mechanism and the roasting mechanism in the containing cavity;

[0045] The roasting mechanism is started, and the roasting mechanism starts to heat the air entering the roasting box 100, so that the hot air flows in the containing cavity and gradually increases the temperature in the containing cavity, thereby creating a suitable high-temperature environment for roasting the article to be roasted;

[0046] If spraying or humidifying is required during the roasting process, for example, related liquid needs to be sprayed during the roasting of a specific article, the spraying mechanism can be started to spray the corresponding liquid to the article to be roasted, and the sprayed liquid will finally fall into the waste liquid tank 400 below and be collected;

[0047] When a certain amount of waste liquid is collected in the waste liquid tank 400, the sealing plug 401 detachably connected at the bottom of the waste liquid tank 400 can be removed, so that the waste liquid is discharged for subsequent proper waste liquid treatment, and then the sealing plug 401 is installed again to continue collecting waste liquid next time;

[0048] After the set baking time, the to-be-baked object reaches the expected baking effect, and then the clamping assembly is driven by the transmission assembly of the clamping mechanism 200 to loosen the clamping of the to-be-baked object, and then the baked object is taken out from the containing cavity of the baking oven 100, completing the entire working process of the baking oven 100.

[0049] Specifically, the baking oven 100 is symmetrically connected with two support plates 103 on the lower side, and a group of support columns 102 are fixedly connected to the lower surfaces of the two support plates 103. Box doors 104 are correspondingly provided on the two side surfaces of the baking oven 100, and the box doors 104 are rotatably connected with the baking oven 100.

[0050] It can be understood that the baking oven 100 is symmetrically connected with two support plates 103 on the lower side, and a group of support columns 102 are fixedly connected to the lower surfaces of the two support plates 103. Such a structure can provide stable support for the baking oven 100. By reasonably distributing the support columns 102, the contact area between the baking oven 100 and the placement plane is increased, so that it is placed more stably. During the operation of the baking oven 100, especially when there are objects inside for baking, there may be some vibration and other conditions, which can effectively prevent the baking oven 100 from shaking, falling and other problems, and ensure the safety of the baking oven 100 and the normal operation of the baking operation;

[0051] And the baking oven 100 is correspondingly provided with box doors 104 on the two side surfaces, and the box doors 104 are rotatably connected with the baking oven 100. This double-side opening design greatly facilitates the operation of the baking oven 100 by the user. For example, when placing objects to be baked in the baking oven 100 or taking out baked objects, the box door 104 can be opened from either side according to the actual situation, avoiding the inconvenience caused by space limitations and other factors, improving the operation efficiency, especially suitable for some large or long objects entering and leaving the baking oven 100, which can more flexibly complete the loading and unloading operation. Moreover, the rotary connection makes the opening and closing of the box door 104 more smooth and labor-saving, further improving the convenience of use.

[0052] Specifically, the first drive motor 201 is bolted and connected to the upper surface of the baking oven 100, the rotating shaft of the first drive motor 201 penetrates into the containing cavity, the bottom end of the rotating shaft of the first drive motor 201 is provided with a turntable 206, a plurality of smoke lifting rods 205 are vertically fixedly connected to the lower surface of the turntable 206, and the bottom of each smoke lifting rod 205 is provided with a limiting block.

[0053] From the above, when the first driving motor 201 centrally fastened on the upper surface of the baking oven 100 is started, the rotating shaft of the first driving motor 201 starts to rotate, and since the rotating shaft penetrates into the accommodating cavity, the rotating disc 206 connected to the bottom end of the rotating shaft will rotate with the rotating shaft. The plurality of smoke lifting rods 205 vertically fixed on the lower surface of the rotating disc 206 also make a circular motion, and the limiting blocks arranged at the bottom of the smoke lifting rods 205 limit the movement of the lower clamping plate 240 of the clamping assembly, so that the movement process can be stable and orderly, and the clamping assembly connected to the smoke lifting rods 205 can be driven to realize corresponding position conversion and other operations, thereby preparing for subsequent clamping and baking of the articles.

[0054] Specifically, the clamping assembly is in the shape of a disc, and a connecting piece 260 is arranged centrally on the clamping assembly. A first gear 270 is arranged on the upper side of the connecting piece 260, and the connecting piece 260 is rotationally connected to the lower side of the smoke lifting rod 205.

[0055] Referring to Figure 3 As shown in the drawings, the clamping assembly further comprises:

[0056] An upper clamping plate 250, the surface of which is in a hollow shape, is fixedly connected to the connecting piece 260, and four through holes are evenly arranged at the edges of the upper clamping plate 250.

[0057] A lower clamping plate 240 is arranged below the upper clamping plate 250, and a connecting rod 210 is arranged on the upper surface of the lower clamping plate 240 at a position corresponding to each through hole. The connecting rod 210 penetrates through the through hole, a limiting plate 280 is arranged at the top of the connecting rod 210, and a hand pulling portion 230 is fixedly connected to the lower surface of the lower clamping plate 240.

[0058] A reset spring 220 is fixedly connected between the upper clamping plate 250 and the lower clamping plate 240, and the reset spring 220 is sleeved on the outer side of the connecting rod 210.

[0059] As known from the above, in the initial state, the upper clamping plate 250 and the lower clamping plate 240 are connected by the reset spring 220, the reset spring 220 is sleeved on the outer side of the connecting rod 210, and the reset spring 220 is in a natural or certain initial extension state, so that the upper clamping plate 250 and the lower clamping plate 240 maintain a certain distance. When it is necessary to clamp the articles, the operator can pull down the lower clamping plate 240 through the hand pulling portion 230 fixedly connected to the lower surface of the lower clamping plate 240, at this time, the connecting rod 210 will move downward along the through hole arranged at the edge of the upper clamping plate 250, and the reset spring 220 is stretched, thereby increasing the distance between the upper clamping plate 250 and the lower clamping plate 240, so as to place the articles to be baked at a suitable position between the upper clamping plate 250 and the lower clamping plate 240.

[0060] After the article is placed, the hand-pulling part 230 is loosened, and under the action of the self-elastic force of the reset spring 220, the lower clamping plate 240 moves upward, and the upper clamping plate 250 and the lower clamping plate 240 gradually approach each other until the article is clamped and fixed between them. At the same time, the first gear 270 is arranged on the upper side of the connecting piece 260 of the clamping assembly, and the connecting piece 260 is rotationally connected with the lower side of the tobacco hanging rod 205, which makes the clamping assembly not only move in position with the tobacco hanging rod 205 when the tobacco hanging rod 205 is driven to move in a circle by the rotating disc 206, but also realize relative rotation and other actions through the first gear 270 and other structures, so as to ensure that the clamped article can be adjusted at multiple angles as needed during the roasting process, and the uniformity and comprehensiveness of roasting are ensured.

[0061] Specifically, the transmission assembly includes a second driving motor 202, which is arranged on the upper surface of the roasting oven 100 and is bolted and fixedly connected with the roasting oven 100. The rotating shaft of the second driving motor 202 penetrates into the accommodating cavity, and the bottom of the rotating shaft is provided with a transmission block 207. The outer surface of the transmission block 207 is provided with a second gear 203, and the outer surface of the transmission block 207 is provided with a transmission chain 204. The second gear 203 is engaged with the outer surface of the transmission chain 204, and the inner surface of the transmission chain 204 is respectively engaged with the first gear 270.

[0062] It can be understood that the motor rotating shaft penetrates into the accommodating cavity, and with the rotation of the rotating shaft, the transmission block 207 arranged at the bottom thereof rotates synchronously. The transmission block 207 serves as an intermediate connection with the transmission component, and when it rotates, the second gear 203 arranged on the outer surface thereof also rotates in a circle.

[0063] Because the second gear 203 is engaged with the outer surface of the transmission chain 204, when the second gear 203 rotates, it drives the transmission chain 204 to rotate. The transmission chain 204 is like a link, which starts to move in a circle along the predetermined route under the driving of the second gear 203, and because the inner surface of the transmission chain 204 is respectively engaged with the first gear 270, in the process of movement of the transmission chain 204, the first gear 270 engaged therewith is also driven to rotate, so as to realize the transmission of the power generated by the second driving motor 202 to the first gear 270 through the transmission block 207, the second gear 203 and the transmission chain 204, and then utilize the rotation of the first gear 270 to drive the clamping assembly to complete the corresponding work task, so as to achieve the purpose that the whole transmission system plays a role in the roasting oven 100.

[0064] Specifically, the inner wall of the accommodating cavity is provided with a slide 105.

[0065] Specifically, the spraying mechanism comprises a water supply pipeline 300, which is annular and provided with a sliding block 304 on the outer side, the sliding block 304 being connected with the sliding groove 105, and a plurality of spray heads 305 being arranged on the inner surface of the water supply pipeline 300, and the water supply pipeline 300 is connected with a high-pressure water pipe 303 at the lower surface, the high-pressure water pipe 303 penetrating through the inner wall of the baking oven 100, and the high-pressure water pipe 303 is connected with a water pump 302 at the end, and the water pump 302 is bolted with a water supply tank 301 at the bottom.

[0066] Specifically, the spray head 305 is arranged at an angle of 45° with the direction of the water supply pipeline 300.

[0067] It can be understood that the sliding groove 105 opened in the inner wall of the accommodating cavity is connected with the sliding block 304 arranged on the outer side of the water supply pipeline 300, and such a structure enables the water supply pipeline 300 to slide along the sliding groove 105, so as to conveniently adjust the position of the water supply pipeline 300 according to different working requirements and different area conditions in the baking oven 100, to ensure that the spraying coverage can be changed as required, and to better adapt to the space layout inside the baking oven 100 and the specific position of the object to be sprayed, thereby improving the pertinence and effectiveness of spraying.

[0068] The spray head 305 is arranged at an angle of 45° with the direction of the water supply pipeline 300, compared with being arranged vertically or at other angles, such an angle enables the sprayed water to be sprayed in a diagonal manner, increases the spraying coverage area of a single spray head 305, and reduces the dead angle of spraying. A plurality of spray heads 305 are distributed on the inner surface of the annular water supply pipeline 300 at such a specific angle, which can form a relatively uniform and extensive spraying area in the baking oven 100 as a whole, to ensure that the surface of the object to be processed and each corner inside the baking oven 100 can be fully sprayed.

[0069] Specifically, the baking mechanism comprises:

[0072] Specifically, the baking oven 100 is provided with an air outlet 505 at the other side surface corresponding to the baking mechanism, and the air outlet 505 is provided with an activated carbon filter screen 506 inside.

[0073] It can be understood that the compressor 503 is arranged above the evaporator 500, and this vertical arrangement is in line with the physical characteristics of hot air rising, facilitating efficient connection between the two through the air inlet pipeline 502, so that the low-temperature and low-pressure gaseous refrigerant flowing out of the evaporator 500 can be smoothly sucked into the compressor 503. The compressor 503 compresses the refrigerant, increases the pressure and temperature of the refrigerant, and then sends the high-temperature and high-pressure refrigerant back to the evaporator 500, so as to form a stable and efficient heat cycle system, which not only makes full use of energy, but also ensures the continuous and stable heat supply required for baking.

[0074] The heater 504 arranged on the side of the compressor 503 further enhances the functional diversity of the baking mechanism. In some special baking process requirements, when the heat generated by the heat cycle is insufficient to meet the rapid heating or reach a specific high temperature requirement, the heater 504 can intervene in time to provide additional heat, accurately control the temperature in the baking oven 100, meet the diversified baking conditions of different food materials and materials, and improve the baking quality and efficiency.

[0075] The baking oven 100 is provided with an exhaust port 505 on the other side of the baking mechanism, which can timely discharge waste gas, moisture and the like generated during the baking process, maintain the air pressure balance in the baking oven 100, and ensure the continuous and stable operation of the baking process. The activated carbon filter screen 506 arranged in the exhaust port 505 plays a key purification role, which can effectively adsorb odor molecules and harmful impurities in the waste gas, avoid direct discharge of untreated dirty air to the surrounding environment, meet the environmental protection requirements, and prevent odor from spreading in the workplace, thereby creating a relatively clean working environment for the operator.

[0076] It can be understood by those skilled in the art that the above description is only a preferred embodiment of the present application and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, and those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement for some technical features.
