[0003] A patent with publication number CN115039902B discloses a tobacco multi-layer curing adjusting device, which belongs to the technical field of tobacco leaf curing. The device includes a lifting adjusting frame arranged in a tobacco curing chamber, multiple curing racks arranged on the lifting adjusting frame, and a lifting mechanism connecting adjacent two curing racks. A temperature and humidity sensor is arranged on the curing rack, and support rods for supporting tobacco leaves are arranged at intervals on the curing rack. The ends of the multiple support rods are connected to a distance adjusting mechanism. The temperature and humidity sensor is connected to the distance adjusting mechanism through a PLC to adjust the distance between adjacent support rods. The device has the advantages of automatically adjusting the distance between support rods according to the curing environment, placing the support rods evenly, and reducing the labor intensity, improving the labor environment, and enhancing the labor efficiency.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0022] As shown in Figures 1 to 4 and Figure 7 , a tobacco multi-layer baking adjusting device according to an embodiment of the present application comprises a support frame 11 and a multi-layer circulating drying box 12 fixedly installed on the inner side wall surface of the support frame 11, a tobacco storage box 13 movably sleeved on the inner side wall surface of the multi-layer circulating drying box 12, and a dehumidification box 14 fixedly installed on the back of the multi-layer circulating drying box 12. The bottom surface of the dehumidification box 14 is fixedly connected with an exhaust pipe 143, a plurality of air-permeable boxes 142 are fixedly installed on the inner side wall surface of the dehumidification box 14, a Y-shaped gas collection strip 141 extending to the inner side wall surface of the air-permeable box 142 is fixedly connected to the top inner side wall surface of the dehumidification box 14, and the air-permeable box 142 is filled with molecular sieve drying agent. The inner side wall surface of the tobacco storage box 13 is movably sleeved with a transmission rod 134, the outer side surface of the transmission rod 134 is staggeredly connected with stirring claws 135, the inner side wall surface of the tobacco storage box 13 is fixedly connected with arc-shaped overlapping plates 133 movably overlapped on the outer side surface of the stirring claws 135, transmission push discs 136 are movably sleeved on both side surfaces of the tobacco storage box 13 and located at both end edge positions of the transmission rod 134, transmission tracks 137 are movably sleeved on the outer side surfaces of the transmission rod 134 and the transmission push disc 136, and a gas collection cavity 126 is arranged on the bottom outer side surface of the multi-layer circulating drying box 12.

[0023] The transmission push plate 136 on the surface of the tobacco storage box 13 slides on the inner surface of the multi-layer circulating drying box 12. The transmission push plate 136 rotates to drive the transmission track 137 and the transmission rod 134 to rotate on the surface of the tobacco storage box 13. The transmission rod 134 rotates to drive the stirring claw 135 to slide on the inner wall surface of the arc-shaped lap plate 133. The staggered fixed stirring claw 135 can continuously divide, mix and stir the tobacco in the arc-shaped lap plate 133. The stirring of the tobacco can effectively reduce the accumulation of the tobacco and increase the water vapor emission effect of the tobacco. When the hot gas carrying water vapor enters the dehumidification box 14, the Y-shaped gas collecting strip 141 compresses the hot gas flow and injects it into the storage air box 142. The molecular sieve desiccant in the storage air box 142 mixes with the incoming hot gas flow and absorbs the water vapor in the hot gas flow, reducing the accumulation of water vapor in the hot gas flow. The multiple storage air boxes 142 perform multiple segmented drying on the hot gas flow, greatly maintaining the hygroscopicity of the molecular sieve desiccant. The exhaust pipe 143 injects the hot gas flow into the heater for secondary heating, so that the dried gas can be re-injected into the gas collecting cavity 126. The dried high-temperature gas quickly dries the tobacco in the tobacco storage box 13.

[0024] As shown in Figures 1 to 2 and Figure 4 The top surface of the tobacco storage box 13 is movably sleeved with a splash-proof air cover 131. The bottom surface of the tobacco storage box 13 is provided with an air-permeable layer 132. The top outer surface of the support frame 11 is provided with a lap guide strip 111 movably lapped on one side edge of the swing closing plate 121. The top surface of the support frame 11 is fixedly installed with a hydraulic rod one 112 at the side edge position. The output end of the hydraulic rod one 112 extends to the inner wall surface of the multi-layer circulating drying box 12. The output end of the hydraulic rod one 112 is fixedly connected with a push plate 113 movably lapped on the outer surface of the tobacco storage box 13. The bottom surface of the support frame 11 is provided with a circulating conveyor 114 on the top surface of the lap storage groove 124. The top surface of the dehumidification box 14 is fixedly installed with a gas guide pipe 144, and the other end of the gas guide pipe 144 extends to the top inner wall surface of the multi-layer circulating drying box 12.

[0025] With the tobacco storage box 13 in the multi-layer circulating drying box 12 inside the continuous pad lifting, the temperature of the tobacco in the top layer of the tobacco storage box 13 inside gradually decreases, and when the tobacco storage box 13 moves to the top of the multi-layer circulating drying box 12, the gas absorption pipe 144 on the top surface of the dehumidification box 14 is matched to the top layer of the tobacco storage box 13 inside the multi-layer circulating drying box 12 to absorb gas. The flow of gas can accelerate the rapid upward movement of the hot gas at the bottom of the multi-layer circulating drying box 12, and the rapid flow of dry hot gas can accelerate the drying speed of the tobacco. At the same time, the moisture in the tobacco storage box 13 is discharged into the dehumidification box 14, and the tobacco storage box 13 closest to the gas inlet of the gas absorption pipe 144 can quickly absorb the hot gas in the tobacco storage box 13 into the dehumidification box 14. The rapid flow of gas can effectively reduce the accumulation of hot gas flow in the tobacco storage box 13.

[0026] When the first tobacco storage box 13 enters the multi-layer circulating drying box 12, the hot gas in the dehumidification box 14 is injected into the gas collection cavity 126 through the exhaust pipe 143. With the continuous accumulation of hot gas in the gas collection cavity 126, the hot gas moves upward and passes through the tobacco in the first tobacco storage box 13 for high-temperature drying. After the tobacco is dried for a period of time, the second tobacco storage box 13 is moved into the multi-layer circulating drying box 12, and the previous tobacco storage box 13 is stacked and raised. The raised tobacco storage box 13 can effectively avoid high-temperature hot gas flow, and the surface temperature of the tobacco away from the high-temperature hot gas flow gradually decreases. When the tobacco storage box 13 is continuously stacked into the multi-layer circulating drying box 12, the previous tobacco storage box 13 is raised, so that each tobacco storage box 13 can be close to the outlet of the high-temperature gas flow, and the tobacco in the tobacco storage box 13 can be in contact with the high-temperature hot gas flow in the first time, thereby achieving the effect of drying the tobacco.

[0028] The tobacco leaf receiving box 13 is lifted by the circulating conveyor 114, and is moved to the inner side wall surface of the lap receiving groove 124, and at the same time the lap sliding strip 125 laps the tobacco leaf receiving box 13, at this time the tobacco leaf receiving box 13 is pushed into the inside of the multi-layer circulating drying box 12 by the hydraulic pusher, at this time the motor 127 rotates the push arm plate 128, one end of the push arm plate 128 is lapped on the bottom surface of the tobacco leaf receiving box 13, and under the transmission of the motor 127, the tobacco leaf receiving box 13 is lifted, and the tobacco leaf receiving box 13 is lapped on the top surface of the lap support plate 129 layer by layer, so that a plurality of tobacco leaf receiving boxes 13 can be lifted layer by layer, and the tobacco leaf receiving box 13 can be stacked in the multi-layer circulating drying box 12 by the transmission of the motor 127, without the need for employees to carry the tobacco leaf receiving box 13; When the tobacco storage box 13 is lifted by the push arm plate 128, the top surface of the tobacco storage box 13 will press the inclined groove surface a4 on the bottom surface of the lapping support plate 129, and the inclined groove surface a4 will move into the cavity a1. At this time, the top surface of the tobacco storage box 13 is not blocked by the lapping support plate 129, and the tobacco storage box 13 will move up to the top surface of the lapping support plate 129. The elastic push wire a2 pushes the lapping support plate 129 in the opposite direction, and the surface of the inclined groove a4 is lapped on the surface of the lapping inclined groove a3, and the position of the lapping support plate 129 is limited. At this time, the tobacco storage box 13 will be lapped on the top surface of the lapping support plate 129 under its own gravity, and the position of the tobacco storage box 13 will be limited. Multiple lapping support plates 129 can limit the position of multiple tobacco storage boxes 13, and multiple tobacco storage boxes 13 can be positioned by the bottom lapping support plate 129 after being stacked together. When the hot air moves up from the bottom layer, it can completely cover the tobacco inside the multiple tobacco storage boxes 13.

[0029] Working principle: cooperate with the circulating conveyor 114 to lift the tobacco storage box 13, and move the tobacco storage box 13 to the inner side wall surface of the lapping receiving groove 124, and at the same time, the lapping sliding bar 125 lapping the tobacco storage box 13. At this time, cooperate with the hydraulic pusher to push the tobacco storage box 13 into the inside of the multi-layer circulating drying box 12. At this time, cooperate with the motor 127 to rotate the push arm plate 128, and make one end of the push arm plate 128 lapped on the bottom surface of the tobacco storage box 13, and under the transmission of the motor 127, the tobacco storage box 13 is lifted, and the tobacco storage box 13 is lapped on the top surface of the lapping support plate 129 layer by layer, so that multiple tobacco storage boxes 13 can be lifted layer by layer. The effect of achieving the use of the transmission of the motor 127 to make the tobacco storage box 13 stacked in the multi-layer circulating drying box 12 without the need for employees to transport the tobacco storage box 13; When the tobacco storage box 13 is pushed up by the push arm plate 128, the top surface of the tobacco storage box 13 will press the inclined groove surface a4 on the bottom surface of the lapping support plate 129, and the inclined groove surface a4 will move into the cavity a1. At this time, the top surface of the tobacco storage box 13 is not blocked by the lapping support plate 129, and the tobacco storage box 13 will move up to the top surface of the lapping support plate 129. The elastic push wire a2 pushes the lapping support plate 129 in the opposite direction, and the surface of the inclined groove a4 is lapped on the surface of the lapping inclined groove a3, and the position of the lapping support plate 129 is limited. At this time, the tobacco storage box 13 will be lapped on the top surface of the lapping support plate 129 under its own gravity, and the position of the tobacco storage box 13 will be limited. Multiple lapping support plates 129 can limit the position of multiple tobacco storage boxes 13, and multiple tobacco storage boxes 13 can be stacked together. The bottommost lapping support plate 129 can limit the position of multiple tobacco storage boxes 13, so that hot air can completely cover the tobacco inside the multiple tobacco storage boxes 13 when it moves up from the bottom layer; When the first tobacco storage box 13 enters the multi-layer circulating drying box 12, the hot air in the dehumidification box 14 is injected into the gas collection cavity 126 through the exhaust pipe 143. With the continuous accumulation of hot air in the gas collection cavity 126, the hot air will move upwards and dry the tobacco inside the first tobacco storage box 13. After a period of time, the second tobacco storage box 13 is moved into the multi-layer circulating drying box 12, and the previous tobacco storage box 13 is stacked and raised. The raised tobacco storage box 13 can effectively avoid high-temperature hot air flow, and the surface temperature of the tobacco will gradually decrease. The previous tobacco storage box 13 is raised when the tobacco storage box 13 is continuously stacked in the multi-layer circulating drying box 12, so that each tobacco storage box 13 can be close to the outlet of the high-temperature air flow, so that the tobacco in the tobacco storage box 13 can be in contact with the high-temperature hot air flow in the first time, and the tobacco can be dried; With the tobacco storage box 13 continuously rising in the inside of the multi-layer circulating drying box 12, the temperature of the tobacco in the inside of the topmost tobacco storage box 13 gradually decreases. When the tobacco storage box 13 moves to the topmost position of the multi-layer circulating drying box 12, the gas in the inside of the topmost tobacco storage box 13 is absorbed by the gas guide pipe 144 on the top surface of the dehumidifying box 14. The flow of the gas can accelerate the rapid upward movement of the hot gas at the bottom of the multi-layer circulating drying box 12. The rapid flow of the dry hot gas stream can accelerate the drying speed of the tobacco. At the same time, the moisture in the inside of the tobacco storage box 13 is discharged into the inside of the dehumidifying box 14. The hot gas in the inside of the tobacco storage box 13 is quickly absorbed into the inside of the dehumidifying box 14 through the gas inlet of the gas guide pipe 144 closest to the topmost tobacco storage box 13. The rapid flow of the gas can effectively reduce the accumulation of the hot gas stream in the inside of the tobacco storage box 13. When the hot gas carrying water vapor enters the inside of the dehumidifying box 14, the Y-shaped gas collecting strip 141 compresses the hot gas stream and injects it into the inside of the storage gas-permeable box 142. The hot gas stream is mixed with the molecular sieve desiccant in the inside of the storage gas-permeable box 142 and the water vapor in the hot gas stream is dehumidified. The hot gas stream is subjected to multiple segmented drying treatment by the plurality of storage gas-permeable boxes 142 to greatly maintain the hygroscopicity of the molecular sieve desiccant. The hot gas stream is injected into the heater through the exhaust pipe 143 for secondary heating treatment. The dry gas can be re-injected into the gas collecting cavity 126. The dry high-temperature gas can quickly dry the tobacco in the inside of the tobacco storage box 13. When the plurality of tobacco storage boxes 13 are continuously stacked and lifted, the transmission driving disc 136 on the two side surfaces of the tobacco storage box 13 slides on the inside surface of the multi-layer circulating drying box 12. The transmission driving disc 136 rotates to drive the transmission track 137 and the transmission rod 134 to rotate on the surface of the tobacco storage box 13. The transmission rod 134 rotates to drive the stirring claws 135 to slide on the inside wall of the arc-shaped lap joint plate 133. The staggered fixed stirring claws 135 can continuously differentiate, stir and mix the tobacco in the inside of the arc-shaped lap joint plate 133. The stirring of the tobacco can effectively reduce the accumulation of the tobacco and increase the moisture evaporation effect of the tobacco.
