[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will combine the drawings in the embodiments of the present utility model to clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3, is a schematic structural diagram of the automatic tobacco leaf conveying device provided by the present utility model. The automatic tobacco leaf conveying device includes at least one fixed feeding platform 11, at least one lifting feeding platform 13, a fixed platform driving component 15 and a lifting platform driving component 17. The fixed feeding platform 11 and the lifting feeding platform 13 are arranged at intervals up and down and are parallel to each other. The fixed platform driving component 15 drives the fixed feeding platform 11 to reciprocate along a predetermined track, and the lifting platform driving component 17 drives the lifting feeding platform 13 to reciprocate along a predetermined track. The lifting feeding platform 13 can move up and down in the vertical direction to be flush with the fixed feeding platform 11. Specifically, the fixed feeding platform 11 and the lifting feeding platform 13 are also used for laying the tobacco leaves flat. Workers neatly lay the tobacco leaves on them and then convey them to the tobacco leaf clamping station for clamping. After the fixed feeding platform 11 directly conveys the tobacco leaves to the clamping station for clamping and during the return journey, the lifting feeding platform 13 conveys the tobacco leaves to a position close to the clamping station and then rises to the clamping station. After clamping is completed, it descends and returns. Then the fixed feeding platform 11 continues to convey, thus forming a cycle.

[0020] Therefore, by providing at least one fixed feeding platform 11 and one lifting feeding platform 13 to alternately convey the tobacco leaves, multiple conveying platforms can alternately operate in a cycle, greatly improving the work efficiency. The lifting feeding platform 13 can move up and down in the vertical direction to change its height, so that it can meet the height requirement for entering the tobacco leaf clamping station just like the fixed feeding platform 11, thus meeting the processing conditions of the next process. Therefore, while improving the work efficiency, it meets the processing procedures, greatly improving the work efficiency. The fixed feeding platform 11 and the lifting feeding platform 13 are arranged at intervals up and down, saving space in terms of structure, reducing the volume of the equipment, and thus reducing the floor area occupied by the equipment.

[0021] Among them, the fixed platform driving component 15 and the lifting platform driving component 17 have the same structure. The fixed platform driving component 15 and the lifting platform driving component 17 are respectively installed on the frame at intervals up and down. The fixed platform driving component 15 drives the fixed feeding platform 11 to reciprocate horizontally, and the lifting platform driving component 17 drives the lifting feeding platform 13 to reciprocate horizontally.

[0022] Such as Figure 2As shown, specifically, in this embodiment, the fixed platform drive assembly 15 and the lifting platform drive assembly 17 both include a mounting beam 171, a positioning plate 172, a rack 173, a gear 174, a guide rail 175, a guide block 176, and a drive motor 177. The rack 173 and the guide rail 175 are mounted on the mounting beam 171. The guide block 176 is fixed on the positioning plate 172 and is fitted with the guide rail 175. The rack 173 meshes with the gear 174. The drive motor 177 is fixed on the positioning plate and is in transmission connection with the gear 174 for driving the gear 174 to rotate to reciprocate along the guide rail 175. The fixed loading platform 11 and the lifting loading platform 13 are both connected and fixed to the positioning plate 172. When the drive motor works, the gear 174 and the rack 173 achieve gear transmission. The gear 174 rolls on the rack 173, causing the positioning plate 172 to move along the guide rail 175, thereby driving the fixed loading platform 11 and the lifting loading platform 13 connected to the positioning plate 172 to reciprocate.

[0023] Specifically, the lifting loading platform 13 includes a tobacco leaf table 131, a bottom support 133, a guide rod 135, and a lifting driver 137. The bottom support 133 is fixedly connected to the drive assembly and is arranged parallel and spaced apart from the tobacco leaf table 131. The guide rod 135 passes through the bottom support 133 and supports the bottom of the tobacco leaf table 131. The lifting driver 137 is fixedly installed on the bottom support 133 and is connected to the bottom of the tobacco leaf table 131 for driving the tobacco leaf table 131 to move up and down. The positioning plate 172 of the lifting drive assembly is connected to the bottom support 133, thereby driving the bottom support 133 to move, and further driving the lifting loading platform 13 to reciprocate horizontally. And the positioning plate 172 of the fixed platform drive assembly is directly connected to the fixed loading platform 11.

[0024] The tobacco leaf table 131 includes a bottom plate 1311, side baffle plates 1313, and a front baffle plate 1315. The side baffle plates 1313 are installed and fixed on the left and right sides of the bottom plate 1311. The front baffle plate 1315 is installed and fixed on the front side of the bottom plate. The side baffle plates and the front baffle plate enclose a semi-enclosed structure, so that the tobacco leaves can be blocked within their placement range to ensure effective clamping of the tobacco leaves. A tobacco clamp groove 1310 is provided on the tobacco leaf table for clamping the tobacco leaves with a tobacco clamp.

[0025] Specifically, in this embodiment, the lifting driver 137 is a cylinder, an oil cylinder, or an electric push rod. Preferably, the lifting driver 137 is a cylinder.

[0026] The fixed loading platform 11 includes a bottom support 111, a flat plate 113, fixed side baffles 115, and a fixed front baffle 117. The tobacco leaves are placed on the flat plate 113. The bottom support 111 is installed on the fixed platform drive assembly. The fixed side baffles 115 are fixedly installed on the left and right sides of the flat plate 113, and the fixed front baffle 117 is fixedly installed on the front side of the flat plate 113. The fixed platform drive assembly is supported below the bottom support 111. The height of the fixed loading platform 11 is non-adjustable. The difference between it and the lifting loading platform 13 is that the fixed loading platform 11 does not have a bottom support, guide rods, and a lifting drive. Similarly, the flat plate 113 is also provided with a tobacco clip groove 1131 for clamping the tobacco leaves and the tobacco clip together.

[0027] Specifically, in this embodiment, there is one fixed loading platform 11 and one lifting loading platform 13. Of course, in other embodiments, there may be two or three fixed loading platforms 11 and lifting loading platforms 13, and the situation can be set according to specific working requirements and scenarios.

[0028] Furthermore, weighing sensors are also installed on the fixed loading platform 11 and the lifting loading platform 13. The weighing sensors are used to detect the weight of the tobacco leaves on the platform in real time. Different alarm sounds will be emitted for overweight or underweight to remind the operator to add or subtract materials.

[0029] The tobacco leaf automatic conveying device provided by the embodiment of the present invention uses at least one fixed loading platform 11 and a lifting loading platform 13 to alternately convey tobacco leaves, so that multiple conveying platforms can operate alternately in a cycle. The lifting loading platform 13 can move up and down in the vertical direction to change its height, so that it can meet the height for entering the tobacco leaf clamping station like the fixed loading platform 11 to meet the processing conditions of the next process. Therefore, while improving work efficiency, the processing process is satisfied, and the work efficiency is greatly improved. The fixed loading platform 11 and the lifting loading platform 13 are arranged at intervals up and down, saving space in terms of structure, reducing the volume of the equipment, and thus reducing the floor area of the equipment. The fixed loading platform 11 has a fixed height.
