Description

[0002] In the packaging process of tobacco leaves, the tobacco leaves need to be loaded into a material box for storage and transportation. During the loading process, the stacking height of the tobacco leaves often slightly exceeds the volume height of the material box, so a pressing device needs to be used to press the tobacco leaves in the material box downward to increase the density of the tobacco leaves and make the tobacco leaves not exceed the volume height of the material box. After pressing, sealing and packaging are needed, and the tobacco leaves in the material box will rebound to a certain height. Due to the influence of gravity, the density of the lower part of the tobacco leaves in the material box is relatively large, and the density of the upper part of the tobacco leaves is relatively small, resulting in uneven distribution of the density of the tobacco leaves in the material box. This density imbalance may cause deviation of the moisture distribution of the tobacco leaves in the long-term storage process, thereby affecting the natural fermentation process of the tobacco leaves and increasing the risk of mold.

CONCRETE EMBODIMENT

[0024] In order to make the technical problems and beneficial effects of the technical solutions of the application more clear and clear, the application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application and not to limit the application.

[0025] Please refer to Figures 1 to 6The utility model provides a vertical turnover device for material caching, including turnover base 1, turnover drive assembly 2 set up on the turnover base 1 and the turnover frame 3 of the turnover base 1 through the turnover drive assembly 2 rotation connection, be equipped with the first transmission component 6 and the second transmission component 7 of opposite setting with the first transmission component 6 with each other cooperation to shift material box from the upper transmission belt 4 to the lower transmission belt 5 on the turnover frame 3, the turnover drive assembly 2 is used to drive the first transmission component 6 and the second transmission component 7 position exchange.

[0026] The vertical turnover device for material caching of the utility model shifts material box from the upper transmission belt to the turnover frame through the first transmission component, and then the turnover drive assembly drives the turnover frame to overturn relative to the turnover base, so that the material box is upside down, and then the second transmission component is used to shift the material box from the turnover frame to the lower transmission belt. The scheme makes the density of the tobacco leaves originally located at the lower part of the material box larger, and the density of the tobacco leaves at the upper part smaller, so that the tobacco leaves are overturned to the upper part and the lower part, and the density of the tobacco leaves in the material box is evenly distributed. The scheme can keep the consistency of the moisture of the tobacco leaves in the long-term storage process, reduce the problem of inconsistent natural fermentation caused by the moisture deviation, and further reduce the risk of tobacco mildew.

[0027] Further, as a preferred embodiment of the scheme, the first transmission component 6 is used to convey the material box from the upper transmission belt 4 to the turnover frame 3 and from the turnover frame 3 to the lower transmission belt 5, or the second transmission component 7 is used to convey the material box from the upper transmission belt 4 to the turnover frame 3 and from the turnover frame 3 to the lower transmission belt 5.

[0028] In the embodiment, the first transmission component and the second transmission component are alternately used to realize the efficient transfer and overturning operation of the material box, ensure that the material box can be smoothly transferred from the upper transmission belt to the lower transmission belt in the overturning process, and improve the efficiency and reliability of the whole material processing process. When the material box reaches the end of the upper transmission belt, the first transmission component 6 receives the material box and transfers it to the turnover frame 3, then the turnover drive assembly 2 drives the turnover frame 3 to overturn by 180°, so that the material box is upside down, and finally the second transmission component 7 transfers the overturned material box to the lower transmission belt 5. In the continuous working process, the second transmission component 7 can be used to transfer the material box to the turnover frame 3 first, and then the material box is overturned after other pretreatment operations, which increases the applicability and flexibility of the device.

[0029] Further, as a preferred embodiment of the present solution but not limited, the turnover driving assembly 2 comprises a plurality of rollers 21 for abutting against and supporting the turnover frame 3, a driving shaft 22 connecting two adjacent rollers 21, and a first driving motor 23 with an output end connected to the driving shaft 22.

[0030] In this embodiment, the abutment of the rollers 21 and the turnover frame 3 can smoothly support the turnover frame 3, ensuring the stability and reliability of the turnover process. The driving shaft 22 connects two adjacent rollers 21, allowing uniform power transmission and ensuring the synchronization of the turnover action. The output end of the first driving motor 23 is connected to the driving shaft 22, providing the driving force required for turnover, making the turnover action more precise and controllable. When the material box needs to be turned over, the first driving motor 23 is started, driving the rollers 21 to rotate through the driving shaft 22, thereby turning the turnover frame 3 along with the material box on it by 180°, achieving the upside-down of the material box. This design not only improves the turnover efficiency, but also reduces the risk of material damage caused by improper turnover. A hydraulic cylinder can also be used instead of the combination of the first driving motor 23 and the rollers 21, and the turnover of the turnover frame 3 can be achieved through the extension and retraction action of the hydraulic cylinder, which is suitable for occasions that require larger turnover force or have special requirements for turnover speed.

[0031] Further, as a preferred embodiment of the present solution but not limited, the turnover frame 3 comprises a circular frame 31 for the rollers 21 to abut against, and a rectangular frame 32 arranged inside the circular frame 31, and the first transmission assembly 6 and the second transmission assembly 7 are respectively arranged on two opposite faces of the rectangular frame 32.

[0032] In this embodiment, the abutment of the circular frame 31 and the rollers 21 ensures the stability and smoothness of the turnover frame 3 during rotation, and the circular design can uniformly disperse the pressure from the rollers 21, reducing structural stress concentration and thus improving the durability and safety of the overall structure. The rectangular frame 32 provides a stable mounting platform for the first transmission assembly 6 and the second transmission assembly 7, and the opposite arrangement allows the material box to be smoothly transferred from one transmission assembly to another before and after turnover without additional adjustment or intervention, greatly improving the transmission efficiency and automation level. It also optimizes the use of space, allowing the turnover frame 3 to accommodate transmission assemblies of sufficient length while maintaining a compact structure, meeting the transmission needs of material boxes of different sizes. The shape and structure of the turnover frame 3 can be adjusted, such as using other geometric frames or changing the layout of the transmission assemblies. However, the combination of the circular frame and the rectangular frame in the present application achieves a good balance in stability, efficiency and space utilization, making it more suitable for production environments that require frequent turnover and transmission operations.

[0033] Further, as a preferred embodiment of the present scheme but not limited, the circular frame 31 is provided with a limiting track 311 arranged along the outer contour thereof and embedded with the roller 21.

[0034] In the present embodiment, the limiting track 311 provides a clear movement path for the roller 21, ensuring that it always rolls along the predetermined track during the turnover process, thereby avoiding the shaking or deflection of the turnover rack 3 caused by the deviation or jumping of the roller 21. Such precise limiting not only improves the safety of the turnover operation, but also makes the control of the turnover angle more accurate, meets the production scenarios with high requirements for turnover precision, prolongs the service life of the equipment, and reduces the maintenance cost.

[0035] Further, as a preferred embodiment of the present scheme but not limited, the first transmission assembly 6 includes a second driving motor 61 arranged on the turnover rack 3, and a plurality of first conveying rods 62 arranged on the turnover rack 3 along the conveying direction, wherein one end of the first conveying rod 62 is provided with a first driven gear 63 close to the second driving motor 61, and the output end of the second driving motor 61 is provided with a first driving gear 64 linked with the first driven gear 63 through a chain.

[0036] In the present embodiment, the second driving motor 61 provides power to drive the first conveying rod 62 to rotate, thereby realizing the stable conveying of the material box. The first driven gear 63 and the first driving gear 64 are linked through a chain, ensuring the stability and synchronization of power transmission, improving the transmission efficiency and reliability. When the material box reaches the end of the upper transmission belt 4, the second driving motor 61 is started to drive the first driven gear 63 and the first conveying rod 62 to rotate through the chain, thereby transferring the material box from the upper transmission belt 4 to the turnover rack 3, or from the turnover rack 3 to the lower transmission belt 5. Alternatively, a synchronous belt can be used instead of a chain transmission to reduce transmission noise and improve transmission accuracy; or a sensor can be arranged on the first conveying rod 62 to monitor the position and state of the material box in real time, thereby realizing more accurate control.

[0037] Further, as a preferred embodiment of the present scheme but not limited, the second transmission assembly 7 includes a third driving motor 71 arranged on the turnover rack 3, and a plurality of second conveying rods 72 rotationally connected to the turnover rack 3 along the conveying direction, wherein one end of the second conveying rod 72 is provided with a second driven gear 73 close to the third driving motor 71, and the output end of the third driving motor 71 is provided with a second driving gear 74 linked with the second driven gear 73 through a chain.

[0038] In this embodiment, the third drive motor 71 provides power to drive the second conveying rod 72 to rotate, thereby achieving stable conveying of the material box. The second driven gear 73 and the second driving gear 74 are connected by a chain to ensure the stability and synchronization of power transmission, improving transmission efficiency and reliability. When the material box reaches the end of the upper transmission belt 4, the third drive motor 71 starts to drive the second driven gear 73 and the second conveying rod 72 to rotate through the chain, transferring the material box from the upper transmission belt 4 to the turnover frame 3, or from the turnover frame 3 to the lower transmission belt 5. Alternatively, a synchronous belt can be used instead of a chain drive to reduce transmission noise and improve transmission accuracy; or a sensor can be installed on the second conveying rod 72 to monitor the position and state of the material box in real time, achieving more accurate control.

[0039] Further, as a preferred embodiment of the present scheme but not limited, it further includes a first guide roller 81 and a second guide roller 82 rotatably connected to the turnover frame 3 between the first transmission assembly 6 and the second transmission assembly 7, and respectively arranged at both ends of the first transmission assembly 6.

[0040] In this embodiment, the first guide roller 81 and the second guide roller 82 can ensure the stability of the material box during transmission, preventing the material box from deviating or jamming during turnover or transmission, thereby improving the reliability and efficiency of the entire transmission system. When the material box is transferred from the upper transmission belt 4 to the turnover frame 3, the first guide roller 81 and the second guide roller 82 guide the two ends of the material box respectively, ensuring that the material box can smoothly enter the first transmission assembly 6 or the second transmission assembly 7. During the turnover process, the guide rollers continue to play a role, ensuring the accurate position of the material box on the turnover frame 3, avoiding turnover failure or material damage due to position deviation. Other possible embodiments include using multiple guide rollers to accommodate different sizes of material boxes, or installing sensors on the guide rollers to monitor the position and state of the material box in real time, achieving more accurate control.

[0041] Further, as a preferred embodiment of the present scheme but not limited, it includes two circular frames 31 and four rollers 21, and two adjacent rollers 21 on the same side of the circular frame 31 collectively support the corresponding circular frame 31.

[0042] In this embodiment, the configuration of two circular frames 31 and four rollers 21 can provide more stable and reliable support, ensuring the stability of the turnover frame 3 during the turnover process. Each circular frame 31 is supported by two adjacent rollers 21. This distribution can evenly distribute the weight of the turnover frame 3, reducing the instability caused by single-point support, thereby improving the reliability and durability of the entire device. When the turnover drive assembly 2 drives the turnover frame 3 to turn over, the rollers 21 roll along the outer contour of the circular frame 31, ensuring smooth turnover.

[0043] Further, as a preferred embodiment of the present scheme, the turnover drive assembly 2 drives the turnover frame 3 to rotate 180° relative to the turnover base 1 in the clockwise or counterclockwise direction.

[0044] In this embodiment, by precisely controlling the turnover angle of the turnover frame 3, it is ensured that the material box can be accurately turned upside down, thereby achieving balanced distribution of the tobacco density in the material box. The working principle is that the turnover drive assembly 2 drives the turnover frame 3 to smoothly rotate 180° in the clockwise or counterclockwise direction through the cooperation of the drive shaft 22 and the roller 21. This precise turnover action not only improves the turnover efficiency, but also reduces the risk of material damage caused by improper turnover.

[0045] The working principle of this embodiment is as follows:

[0046] A vertical turnover device for material storage according to the present application, after the material box that has been pressed and sealed is transferred from the upper transmission belt to the turnover frame by the first transmission assembly, the turnover drive assembly drives the turnover frame to turn over relative to the turnover base, so that the material box is turned upside down, and then the second transmission assembly transfers the material box from the turnover frame to the lower transmission belt. This scheme makes the tobacco with higher density originally located in the lower part of the material box after turnover be turned to the upper part, while the tobacco with lower density in the upper part be turned to the lower part by gravity, ensuring balanced distribution of the tobacco density in the material box. The uniformity of tobacco moisture is maintained during long-term storage, reducing the problem of inconsistent natural fermentation caused by moisture deviation, thereby reducing the risk of tobacco mildew.
