Description

Technical Field

[0002] In agricultural production, the stability and purity of crop leaves (tobacco leaves) have always been a difficult problem that has troubled all kinds of technicians. The leaves (tobacco leaves) required in the market require manual selection processes to improve purity and remove debris. However, in the manual leaf selection process, there are unfavorable factors such as the older age structure of leaf selectors, difficulty in achieving a balanced vision, fatigue caused by high-intensity work requirements, and dust flying in the working environment. It is difficult to stably select leaves with high grade compliance and good purity. Therefore, the use of artificial intelligence to improve the purity of leaves (tobacco leaves) will be a key link in the processing process in the future.

[0003] At present, the field of leaf (tobacco) selection adopts three modes: stall-style leaf selection, table-style leaf selection and human-machine combination leaf selection, and the main work is still done manually. With the continuous advancement of China's scientific and technological innovation, the research on modern leaf selection is constantly advancing, and the research and application of optical recognition systems are increasing. However, the stretching and placement of leaves (tobacco leaves) still requires manual arrangement of single layers on the leaf conveying platform, and then classification and screening through the optical recognition system. The key link of using machines to select leaves has not been broken through, which greatly hinders the application of artificial intelligence leaf selection. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] On the contrary, the present application covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present application as defined by the claims. Further, in order to make the public have a better understanding of the present application, some specific details are described in detail in the detailed description of the present application below. Those skilled in the art can fully understand the present application without the description of these details.

[0029] The following will be combined Figure 1-9A blade stretching arrangement device involved in the embodiment of the present application is described in detail. It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0030] In the embodiments of the present application, Figure 1 As shown, the blade stretching and arranging device may include: a floating stretching device for suspending the blades in the air and making the blades stretch out; and a wind suction conveying device for adsorbing and transporting the blades stretched in the air to a preset position.

[0031] In actual work, the whole bag of primary roasted leaves (tobacco leaves) are not stretched out one by one. The device of the present application is used to stretch out the whole bag of primary roasted leaves (tobacco leaves) one by one, so as to provide preliminary equipment technical support for the next step of artificial intelligence to accurately identify each tobacco leaf, automatically classify the tobacco leaves of corresponding grades, and remove debris and leaves that do not meet the requirements.

[0032] In some embodiments, Figure 2 and 4 As shown, the vortex floating stretching device includes: a vortex floating wind outlet cover, a blade rotation chamber 9 is provided inside the vortex floating wind outlet cover, and the side wall of the vortex floating wind outlet cover is used to generate a vertical oblique wind force relative to the inner periphery of the blade rotation chamber 9; an air regulating component 4, the air regulating component 4 is used to generate an oblique rising wind force relative to the bottom of the blade rotation chamber 9; and a suspended fan is used to provide the power required for the vertical oblique wind force inside the inner periphery of the blade rotation chamber 9 and the bottom oblique rising wind force.

[0033] After the blades are conveyed into the blade rotating chamber 9, the suspension fan starts working, and generates an upward wind force obliquely relative to the bottom of the blade rotating chamber 9 and a vertical wind force obliquely relative to the periphery of the blade rotating chamber 9 through the air regulating component 4 and the rotary floating wind cover arranged at the bottom. The combined force of the two can make the blades (tobacco leaves) rotate at high speed along the central axis of the blade rotating chamber 9, so that the blades are stretched out, and the stretched blades rotate and rise rapidly under the action of the bottom suspension force.

[0034] In some embodiments, the swirl-floating air hood comprises: an inner shell 11 and an outer shell 13 which penetrate in the axial direction. Figure 3 As shown, the side walls of the inner shell 11 and the outer shell 13 are provided with blade inlets 12 arranged opposite to each other. An air inlet interlayer 10 is provided between the inner shell 11 and the outer shell 13. The top of the air inlet interlayer 10 is sealed, and the bottom of the air inlet interlayer 10 is open. The side wall of the inner shell 11 is provided with a plurality of first inlet and outlet holes 8 which are sequentially penetrated and tangent to the inner wall of the inner shell 11, as shown in FIG. Fig. 9 shown.

[0035] By opening the blade inlet 12, continuous assembly line operation can be achieved. After the blade enters the blade rotation chamber 9 from the blade inlet 12, it is stretched and spirally ascended. Among them, the wind force obliquely cut in the vertical direction relative to the inner periphery of the blade rotation chamber 9 plays a very important role in the stretching of the blade. The wind force obliquely cut in the vertical direction relative to the inner periphery of the blade rotation chamber 9 is generated by a suspension fan. The wind force generated by the suspension fan is divided into two parts, one part of which generates an oblique ascending wind force relative to the bottom of the blade rotation chamber 9 through the air regulating component 4. The other part enters the air inlet interlayer 10, and then enters the blade rotation chamber 9 through the first cut-in and air outlet holes 8 in turn, forming a wind force obliquely cut in the vertical direction relative to the inner periphery of the blade rotation chamber 9. In this embodiment, six layers of first cut-in and air outlet holes 8 are provided on the side wall of the inner shell 11, which are arranged in sequence and tangent to the inner wall of the inner shell 11. Each layer has three first cut-in and air outlet holes 8, and the three first cut-in and air outlet holes 8 are arranged at equal intervals. The cutting angle between the first cut-in and air outlet holes 8 and the tangent of the inner shell 11 is 16°-18°. This angle can form a simulated hurricane with the central axis of the blade rotation chamber 9 as the center, so that the blades (tobacco leaves) entering the blade rotation chamber 9 can rotate centrifugally at high speed.

[0036] In some embodiments, Figure 5-8 As shown, the air regulating component 4 includes an air outlet plate 14 and an air regulating plate 15. The air outlet plate 14 is provided with at least one group of second cut-in air outlet holes 16 arranged in a circular pattern. The air regulating plate 15 is provided with an air inlet 17 for adjusting the air volume of the second cut-in air outlet holes 16. The air outlet plate 14 is sealed and connected to the inner wall of the blade rotating chamber 9. The air regulating plate 15 is rotatably arranged on the side of the air outlet plate 14 facing the suspension fan. Each group of second cut-in air outlet holes 16 arranged in a circular pattern is provided with 6, and similarly, there are 6 air inlets 17. The 6 second cut-in air outlet holes 16 are arranged at equal intervals.

[0037] The reason for setting the air regulating component 4 is to convert the wind force generated by the suspension fan into a spiral upward wind force, that is, an upward wind force obliquely cut relative to the bottom of the blade rotating chamber 9. Since the second cut-in and outlet holes 16 arranged in a circular shape in sequence on the air outlet plate 14 have a guiding function, and the cutting angle between the second cut-in and outlet holes 16 and the air outlet plate 14 is 16°-18°, at this angle, it is easier to form a high-speed centrifugal rotating wind along the central axis, and the blades (tobacco leaves) float above the blade rotating chamber 9 under the action of the lifting force.

[0038] The lifting force of the blade, i.e. the oblique rising wind force relative to the bottom of the blade rotating chamber 9, can be adjusted; specifically, it is achieved by adjusting the relative positions of the air outlet plate 14 and the air regulating plate 15. In this embodiment, the air outlet plate 14 is fixed on the inner wall of the inner shell 11 and is sealed, and the air regulating plate 15 is placed below the air outlet plate 14 and is coaxially arranged with the air outlet plate 14. When the air regulating plate 15 is rotated, the relative positions of the air inlet 17 on the air regulating plate 15 and the second cut-in air outlet hole 16 will change, and the hole size of the second cut-in air outlet hole 16 will change, so the air volume through the second cut-in air outlet hole 16 will change. It is convenient to adjust according to the batches, sizes, and humidity of the leaves (tobacco leaves).

[0039] In some embodiments, the second cut-in air outlet holes 16 arranged in a circular pattern are provided in two groups, and the two groups of the second cut-in air outlet holes 16 arranged in a circular pattern are concentrically arranged, including an inner circle of second cut-in air outlet holes 16 and an outer circle of second cut-in air outlet holes 16. The two groups of second cut-in air outlet holes 16, one large and one small, help to better provide an oblique rising wind force relative to the bottom of the inner part of the blade rotation cavity 9.

[0040] In some embodiments, the suspension fan includes a centrifugal fan 3 and a fan base 1, the fan base 1 is arranged through from top to bottom, the centrifugal fan 3 is arranged below the air regulating component 4, and the centrifugal fan 3 is arranged on a bracket of the fan base 1, and the fan base 1 is sealed and connected to the outer shell 13 through matching steps. The centrifugal fan 3 mainly provides wind power. There are matching steps between the fan base 1 and the outer shell 13 for easy assembly.

[0041] In some embodiments, the wind suction conveying device includes a wind suction device 7, a first conveyor belt 6 and a second conveyor belt 5, the first conveyor belt 6 is provided with a plurality of ventilation holes, and there is at least a height difference between the first conveyor belt 6 and the second conveyor belt 5 that can accommodate the passage of blades; the first conveyor belt 6 and the second conveyor belt 5 are arranged in parallel and overlap at least at one end, the end of the first conveyor belt 6 away from the second conveyor belt 5 is arranged above the blade rotation chamber 9, and the wind suction device 7 is arranged opposite to the blade rotation chamber 9, and is arranged above the first conveyor belt 6.

[0042] The main function of the wind suction conveying device is that when the leaves (tobacco leaves) are blown and stretched by the swirl and stretch device and swirl and float up, the wind suction device 7 generates negative pressure suction, which is transmitted to the lower end surface of the first conveyor belt 6 through the ventilation holes, and the stretched leaves are adsorbed and transmitted through the first conveyor belt 6. When the first conveyor belt 6 moves out of the negative pressure area, the negative pressure disappears, and the leaves automatically fall onto the second conveyor belt 5. Single leaves (tobacco leaves) are arranged in layers in sequence. The single-layer arranged tobacco leaves are transported to the tobacco leaf visual recognition system for tobacco leaf grading.

[0043] In some embodiments, the angle between the first conveyor belt 6 and the second conveyor belt 5 is between 0° and 180°. The first conveyor belt 6 and the second conveyor belt 5 only need to partially overlap, and both are running in the counterclockwise direction. Preferably, the first conveyor belt 6 and the second conveyor belt 5 are arranged in parallel. Of course, according to the layout conditions of the site, the first conveyor belt 6 and the second conveyor belt 5 can also be arranged vertically or at a certain angle.

[0044] In some embodiments, the width of the first conveyor belt 6 is smaller than the width of the second conveyor belt 5. For example, the width of the first conveyor belt 6 is 10 cm smaller than the width of the second conveyor belt 5.

[0045] In some embodiments, the width of the first conveyor belt 6 is greater than the width of the second conveyor belt 5. For example, the width of the first conveyor belt 6 is greater than the width of the second conveyor belt 5 by 10 cm.

[0046] In some embodiments, the width of the first conveyor belt 6 is equal to the width of the second conveyor belt 5 .

[0047] In some embodiments, the distance between the suction port of the air suction device 7 and the first conveyor belt 6 is 5-20 cm. Of course, this width can also be adjusted according to actual conditions, including the suction port of the air suction device 7 can also be adjusted according to the size of the leaf (tobacco leaf), for example, the mouth of the suction port can be shrunk or enlarged.

[0048] Of course, the first conveyor belt 6 can also be a conveyor belt with a screen, so that it is easier to generate negative pressure to adsorb the blades through the wind suction device 7. Since the screen part that has adsorbed the blades cannot adsorb the blades again, the device of the present application can achieve a stretched arrangement of a single layer of blades.

[0049] The beneficial effects that may be brought about by a leaf stretching and arranging device disclosed in the present application include but are not limited to: the purpose of the present invention is to stretch and arrange a whole bag of leaves (tobacco leaves) after initial baking one by one, so as to provide preliminary equipment technical support for the next step of artificial intelligence to accurately identify each tobacco leaf, automatically classify tobacco leaves of corresponding grades, and remove debris and leaves that do not meet the requirements. This device follows the hurricane principle in wind dynamics, uses rotating airflow to rotate and stretch the tobacco leaves along the central axis, and under the negative pressure of the rolling screen, the tobacco leaves are arranged in single pieces on the leaf conveying platform, so as to realize the stable control of the leaf posture by artificial intelligence to achieve the effect of accurate detection.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
