TECHNICAL FIELD
[0001] The present application relates to the technical field of cigarette production, and particularly relates to a cut tobacco drying device. BACKGROUND
[0002] In the tobacco cutting process, the drying process is one of the key processes affecting the quality of cut tobacco, and the drying drum as the core equipment of the process is directly related to the uniformity of the moisture content of cut tobacco, color, aroma and other important indicators. However, in the actual production process, the drying process generally has the problem of dry head and dry tail of cut tobacco, which brings many adverse effects on the quality and production efficiency of tobacco products.
[0003] Specifically, at the initial stage of the drying process, the initial cut tobacco sent into the drying drum has the problem of dry head due to the small amount and low flow rate of cut tobacco, which causes the moisture content of the cut tobacco to be too low and the texture to be dry and brittle. In the subsequent rolling process, not only the filling performance of the cigarette is affected, leading to inconsistent tightness of the cigarette, but also the cigarette is prone to produce a burnt taste during combustion, which seriously affects the taste and quality of the cigarette. In addition, at the end stage of the drying process, the amount of cut tobacco sent into the drying drum at the end is also reduced, so that the end part of the cut tobacco is greatly roasted and the humidity evaporation amount is larger, resulting in the dry tail phenomenon. The dry tail cut tobacco also has the problem of substandard moisture content, which causes waste of cut tobacco and increases production cost.
[0004] In view of the above problems, in order to ensure the overall quality of cut tobacco, the dry head and dry tail cut tobacco need to be handled separately in the production process, which not only increases the production process and labor cost, but also reduces the production efficiency. Moreover, due to the existence of dry head and dry tail cut tobacco, the quality of each batch of cut tobacco fluctuates, making it difficult to achieve stability and consistency of product quality. SUMMARY
[0005] Therefore, it is necessary to provide a cut tobacco drying device to solve the problems of poor drying quality of traditional technology, waste of cut tobacco, high production cost and low production efficiency.
[0006] The present application provides a cut tobacco drying device, which comprises:
[0007] A cut tobacco conveying mechanism, which has a cut tobacco inlet end, and is provided with a material dropping port arranged close to the cut tobacco inlet end and a material supplementing port arranged away from the cut tobacco inlet end;
[0008] An opening and closing mechanism, which is arranged on the cut tobacco conveying mechanism and can open or close the material dropping port; and
[0009] The tobacco replenishing mechanism is arranged on one side of the tobacco conveying mechanism, and opposite ends of the tobacco replenishing mechanism are respectively provided with a receiving port and a feeding port. The tobacco in the tobacco replenishing mechanism moves from the receiving port to the feeding port. The receiving port is arranged below the discharging port in a position opposite to the discharging port. The feeding port is connected with the replenishing port.
[0010] The tobacco drying device of the scheme is applied to a processing scene of tobacco drying. During production, the tobacco is conveyed by the tobacco conveying mechanism to be conveyed to a drying station. Considering that the number of tobacco in the initial stage and the end stage is small, the tobacco in the two stages is easily subjected to excessive heating after entering the drying station, resulting in serious water loss and dry head and dry tail problems. Therefore, the scheme of arranging the tobacco replenishing mechanism on one side of the tobacco conveying mechanism is adopted. Specifically, when the tobacco in the initial stage moves along the tobacco conveying mechanism and passes through the discharging port, the opening and closing mechanism is started and the discharging port is opened, so that part of the tobacco in the middle part of the tobacco conveying mechanism falls into the tobacco replenishing mechanism through the abutting and communicating discharging port and receiving port, and the tobacco replenishing mechanism drives the received part of the tobacco to move to the feeding port. On this basis, when the two parts of tobacco with small quantity in the initial stage and the end stage reach the position of the replenishing port of the tobacco conveying mechanism, the part of the tobacco in the tobacco replenishing mechanism can be sent out from the feeding port under the driving of the tobacco replenishing mechanism, and then falls into the tobacco conveying mechanism through the replenishing port, so as to form mixing with the two parts of tobacco in the initial stage and the end stage in sequence, so as to form the effect of supplementing and increasing the quantity of the two parts of tobacco in the initial stage and the end stage. In this way, after the two parts of tobacco in the initial stage and the end stage with increased quantity enter the drying station for drying treatment, the problem of excessive drying and serious water loss can be well avoided, the dry head and dry tail problem can be prevented, the quality of the dried tobacco can be effectively improved, the increase of production cost caused by unqualified quality of the dried tobacco can be controlled, the manpower for separately processing the dry head and dry tail tobacco can be avoided, and the production efficiency is ensured.

When an element is referred to as being "connected" to another element, it can be directly connected to the other element or can exist with a mediating element in between. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar expressions used herein are used for illustrative purposes only and are not intended to be the only implementation.
[0036] Referring to Figure 1 An example of a tobacco drying device 100 for tobacco is shown in the present application, which can improve the moisture uniformity, color, aroma and other important indicators of tobacco by processing the tobacco through a drying process, thereby helping to obtain better cigarette quality.
[0037] Exemplarily, the tobacco drying device 100 includes a tobacco conveying mechanism 10, an opening and closing mechanism 20, and a tobacco replenishing mechanism 30.
[0038] The tobacco conveying mechanism 10 has a tobacco entry end 11. That is, the tobacco processed through the upstream process can enter the tobacco conveying mechanism 10 through the tobacco entry end 11.
[0039] The tobacco conveying mechanism 10 is also provided with a material dropping port 12 arranged close to the tobacco entry end 11, and a material replenishing port 13 arranged away from the tobacco entry end 11; the opening and closing mechanism 20 is arranged on the tobacco conveying mechanism 10, and the opening and closing mechanism 20 can open or close the material dropping port 12.
[0040] It is to be noted that when the opening and closing mechanism 20 closes the material dropping port 12, the tobacco can normally move through the material dropping port 12 under the driving action of the tobacco conveying mechanism 10. When the opening and closing mechanism 20 opens the material dropping port 12, the tobacco moves to the material dropping port 12 and then falls from the material dropping port 12 under the action of its own gravity.
[0041] The shape and size of the material dropping port 12 can be flexibly selected according to actual needs, as long as it can be closed by the opening and closing mechanism 20 and in the open state, allowing the tobacco to fall by itself.
[0042] Please continue to refer to Figure 1 The tobacco replenishing mechanism 30 is arranged on one side of the tobacco conveying mechanism 10, and the opposite ends of the tobacco replenishing mechanism 30 are respectively provided with a material receiving port 31 and a material feeding port 32. The tobacco in the tobacco replenishing mechanism 30 moves from the material receiving port 31 to the material feeding port 32. The material receiving port 31 is arranged below the material dropping port 12, and the material feeding port 32 is connected with the material replenishing port 13.
[0043] In summary, the implementation of the technical scheme of the embodiment will have the following beneficial effects: the cut tobacco drying device 100 of the scheme is applied to the processing scene of drying cut tobacco. During production, the cut tobacco is conveyed by the cut tobacco conveying mechanism 10 to be delivered to the drying station. Considering that the number of cut tobacco in the initial stage and the end stage is small, the cut tobacco in these two parts is prone to be over-heated after entering the drying station, resulting in serious water loss and dry head and dry tail problems. Therefore, the scheme of arranging the cut tobacco supplement mechanism 30 on one side of the cut tobacco conveying mechanism 10 is adopted. Specifically, when the cut tobacco in the initial stage moves along the cut tobacco conveying mechanism 10 and passes through the discharge port 12, the opening and closing mechanism 20 is started and the discharge port 12 is opened, so that part of the cut tobacco in the middle part of the cut tobacco conveying mechanism 10 falls into the cut tobacco supplement mechanism 30 through the butt joint of the discharge port 12 and the receiving port 31, and the cut tobacco supplement mechanism 30 drives the received cut tobacco to move to the feeding port 32.
[0044] On this basis, when the two parts of cut tobacco with small quantity in the initial stage and the end stage reach the position of the supplement port 13 of the cut tobacco conveying mechanism 10, the cut tobacco in the cut tobacco supplement mechanism 30 can be sent out from the feeding port 32 under the driving of the cut tobacco supplement mechanism 30, and then fall into the cut tobacco conveying mechanism 10 through the supplement port 13, so as to form mixing with the two parts of cut tobacco in the initial stage and the end stage in turn, so as to form the effect of supplementing and increasing the quantity of the two parts of cut tobacco in the initial stage and the end stage. In this way, after the two parts of cut tobacco in the initial stage and the end stage with increased quantity enter the drying station for drying treatment, the problem of over-drying and serious water loss can be well avoided, the dry head and dry tail problem can be prevented, the quality of cut tobacco drying can be effectively improved, the increase of production cost caused by unqualified cut tobacco after drying can be controlled, and the scheme can avoid the need to configure manpower to separately process the dry head and dry tail cut tobacco, thereby ensuring the production efficiency.
[0045] Please continue to refer to Figure 1 In addition, on the basis of the above-mentioned embodiment, the cut tobacco drying device 100 further comprises a controller and a first position sensor 40, the first position sensor 40 is arranged at the cut tobacco inlet end 11, and the first position sensor 40 and the opening and closing mechanism 20 are electrically connected with the controller.
[0046] The first position sensor 40 arranged at the first position of the tobacco entering end 11 can detect the tobacco conveyed from the upstream station to the tobacco entering end 11, and then can feed back a signal to the controller, so that the controller obtains the signal of the tobacco entering the tobacco conveying mechanism 10. According to the preset waiting time interval in the controller, a small amount of tobacco in the tobacco conveying mechanism 10 can be normally moved; when the waiting time interval is over, the controller can control the opening and closing mechanism 20 to open the tobacco dropping port 12, so that the middle tobacco can be dropped from the tobacco dropping port 12 to the tobacco supplementing mechanism 30 under the action of the self weight. The degree of automation is high, and the action of the opening and closing mechanism 20 can be accurately controlled by means of the signal detection of the first position sensor 40 and the logical setting of the controller.
[0047] For example, in an optional embodiment, the opening and closing mechanism 20 comprises a driver, a connecting rod 22 and an opening and closing baffle. The driver is arranged on the tobacco conveying mechanism 10, and the driver is rotationally connected with one end of the connecting rod 22. The opening and closing baffle is rotationally arranged on the tobacco conveying mechanism 10 through a rotating shaft, and the opening and closing baffle is rotationally connected with the other end of the connecting rod 22.
[0048] In operation, when the driver drives the connecting rod 22 to rotate in a first direction (for example, clockwise), the connecting rod 22 can drive the opening and closing baffle to rotate close to the tobacco dropping port 12, and finally to block and close the tobacco dropping port 12. When the driver drives the connecting rod 22 to rotate in a second direction (for example, counterclockwise), the connecting rod 22 can drive the opening and closing baffle to rotate away from the tobacco dropping port 12, so as to open the tobacco dropping port 12. The structure and working principle of the opening and closing mechanism 20 are simple, the response speed of the opening and closing baffle driven by the driver is fast, which is helpful to accurately block and open the tobacco dropping port 12, so as to control the amount of the tobacco dropped from the tobacco conveying mechanism 10 to the tobacco supplementing mechanism 30.
[0049] Please continue to refer to Figure 3 More specifically, in an embodiment, the driver is a pneumatic cylinder 21, and the opening and closing mechanism 20 further comprises an air compressor 23 and an electromagnetic valve 24. The air compressor 23 and the electromagnetic valve 24 are communicated through a pipeline, and the electromagnetic valve 24 and the pneumatic cylinder 21 are communicated through a pipeline. By arranging the air compressor 23 and the electromagnetic valve 24, the pneumatic cylinder 21 can be accurately supplied with compressed air flow, so as to ensure that the pneumatic cylinder 21 can accurately drive the piston rod to extend or retract, and then to accurately control the opening and closing of the tobacco dropping port 12.
[0050] For example, the tobacco replenishing mechanism 30 in the present application is arc-shaped, and the arc-shaped concave side of the tobacco replenishing mechanism 30 is arranged towards the tobacco conveying mechanism 10. Since the tobacco replenishing mechanism 30 is designed as an arc-shaped structure as a whole, the tobacco replenishing mechanism 30 can be arranged on one side of the tobacco conveying mechanism 10, and the receiving port 31 thereof can be bent to be directly below the dropping port 12 so as to receive the tobacco falling from the dropping port 12 when the dropping port 12 is opened. Meanwhile, since the arc-shaped concave side of the tobacco replenishing mechanism 30 is arranged towards the tobacco conveying mechanism 10, the feeding port 32 of the tobacco replenishing mechanism 30 can be easily bent to be above the replenishing port 13 so as to replenish the tobacco to the tobacco in the initial stage and the end stage.
[0051] Optionally, the tobacco conveying mechanism 10 and the tobacco replenishing mechanism 30 in the present application can adopt any mature type of product conveying device in the prior art, such as a conveying belt mechanism, a conveying chain plate mechanism, a conveying vehicle mechanism, etc., which can be flexibly selected according to actual needs, and is not specifically limited herein.
[0052] In addition, on the basis of any of the above embodiments, the tobacco drying device 100 further comprises a tobacco dryer 50, and the tobacco conveying mechanism further has a tobacco delivery end 14, which is located at the opposite end of the tobacco conveying mechanism from the tobacco entering end 11, and is in communication with the tobacco drying cavity of the tobacco dryer 50.
[0053] In actual processing, the initial stage tobacco and the end stage tobacco replenished in quantity, and the middle tobacco between the two parts of tobacco will be sequentially fed into the tobacco dryer 50 under the driving of the tobacco conveying mechanism 10, so as to receive the drying treatment of the tobacco dryer 50, so that the moisture content of the tobacco finally discharged from the tobacco dryer 50 is uniform, and the color and aroma quality are good.
[0054] Please continue to refer to Figure 1 Further, in still another embodiment, the tobacco drying device 100 further comprises a second position sensor 60, which is arranged at the tobacco delivery end 14, and the second position sensor 60 and the tobacco dryer 50 are both electrically connected with the controller. When the second position sensor 60 detects the tobacco, a feedback signal is immediately fed to the controller, so that the controller sends a working instruction to the tobacco dryer 50, so as to avoid the waste of energy caused by the fact that the tobacco dryer 50 has started to operate before the tobacco arrives, or the fact that the tobacco dryer 50 has not normally started to operate after the tobacco has been fed into the tobacco dryer 50, thereby affecting the processing efficiency of the tobacco drying.
[0055] Optionally, the first position sensor 40 and the second position sensor 60 can be, but are not limited to, any one of an infrared sensor, a proximity switch, a laser sensor, etc., which can be flexibly selected according to actual needs.
[0056] Please continue to refer toFigure 1 Further, the tobacco drying device 100 for the cut tobacco further comprises a humidifying mechanism 70, which is arranged on the tobacco drying machine 50 and located at the entrance of the drying chamber. When the cut tobacco reaches the entrance of the drying chamber, the humidifying mechanism 70 can spray water on the cut tobacco to increase the moisture and water content of the cut tobacco, so as to avoid the problem of dry head and dry tail caused by the excessive evaporation of water after the cut tobacco enters the tobacco drying machine 50 for drying.
[0057] For example, in an optional embodiment, the humidifying mechanism 70 comprises a water storage container, a water feeding pump, a water feeding pipeline and a spray nozzle, the water storage container is communicated with the spray nozzle through the water feeding pipeline, the water feeding pump is arranged in the water feeding pipeline, and the spray nozzle is arranged at the entrance of the drying chamber. In operation, the water feeding pump is started to generate a driving force to drive the water in the water storage container to flow along the water feeding pipeline to the spray nozzle and form a certain water pressure in the spray nozzle, so that the water can finally be sprayed in the form of mist from the spray nozzle to the cut tobacco, the spraying area is large and the water mist is uniformly distributed, which ensures that the water mist and the cut tobacco are more uniformly contacted and combined, thereby ensuring that the moisture and water content of each part of the cut tobacco are uniform and consistent, and ensuring the quality of the dried cut tobacco.
[0058] Please continue to refer to Figure 4 Further, the humidifying mechanism 70 further comprises a driving motor 71, a driving gear 72, an arc-shaped rack 73 and an arc-shaped guide rail 74, the motor shaft of the driving motor 71 is coaxially connected with the driving gear 72, the driving gear 72 is engaged with the arc-shaped rack 73, the arc-shaped rack 73 is slidably arranged on the arc-shaped guide rail 74, and the spray nozzle 75 is installed on the arc-shaped rack 73, so that the spray nozzle 75 can swing back and forth along the arc-shaped track around the entrance of the drying chamber.
[0059] In actual operation, the area of the cut tobacco spread on the cut tobacco conveying mechanism can be larger than the distribution area of the mist sprayed by the spray nozzle 75, or the cut tobacco covered by the lower layer of cut tobacco can be blocked by the upper layer of cut tobacco and cannot directly face the spray nozzle 75 due to the stacking of the cut tobacco, so that the mist sprayed by the spray nozzle 75 cannot uniformly moisten all the cut tobacco moving through the entrance of the drying chamber, thereby affecting the quality of the dried cut tobacco.
[0060] In view of the above problems, the driving motor 71 drives the driving gear 72 to rotate, the driving gear 72 can drive the arc-shaped rack 73 to move back and forth along the arc-shaped guide rail 74 through the engagement of the gear structure, so that the arc-shaped rack 73 can drive the spray nozzle 75 to swing back and forth along the arc-shaped track around the entrance of the drying chamber, ensuring that the mist sprayed by the spray nozzle 75 can completely contact the spread cut tobacco from all angles, expanding the spraying area and range of the spray nozzle 75, and at the same time, a part of the mist can directly contact the upper layer of cut tobacco, and another part of the mist can directly contact the lower layer of cut tobacco from the side of the stacked cut tobacco pile, ensuring that all the cut tobacco can be uniformly moistened.
[0061] Specifically, in one embodiment, the cut tobacco dryer 50 comprises a frame 51, a driving mechanism 52 and a drying drum 53, the drying drum 53 is rotatably arranged in the frame 51, the driving mechanism 52 is arranged on the frame 51 and connected with the drying drum 53, and is used to drive the drying drum 53 to rotate.
[0062] The frame 51 is in a U-shaped structure, and is used to load the integrated driving mechanism 52 and the drying drum 53. The drying drum 53 is installed into the U-shaped cavity of the frame 51, so that the opposite two ends of the drying drum 53 can be rotatably installed with the frame 51 at the same time, which helps to improve the firmness of the installation of the drying drum 53 and the stability of the rotation. On this basis, the driving mechanism 52 is used to drive the drying drum 53 to rotate, so that the cut tobacco in the drying cavity of the drying drum 53 can be driven to produce tumbling and shaking, thereby ensuring that all the cut tobacco can be uniformly baked and heated, and ensuring the quality of the cut tobacco.
[0063] Please continue to refer to Figure 2 In addition, the cut tobacco dryer 50 further comprises a protective cover 54, which is in a cuboid structure, and is arranged outside the frame 51, the driving mechanism 52 and the drying drum 53, and plays a protective role, avoiding that people or objects in the environment accidentally contact the rotating drying drum 53 and cause safety accidents, and improving the appearance and simplicity of the cut tobacco dryer 50.
[0064] The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
[0065] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
