[0002] Cold chain logistics generally refers to a systematic project that keeps refrigerated and frozen foods in a specified low-temperature environment throughout the production, storage, transportation, and sales process before consumption, in order to ensure food quality and reduce food loss. Currently, the cold chain warehousing of logistics generally has a large number of goods of complex types, which require shelves to be stacked for storage.

[0003] At present, a Chinese patent discloses a cargo stacking device for logistics cold chain warehousing, and its application number is 2023214103741. It is equipped with a motor, a rotating rod, a driving wheel, a driven wheel, a threaded column, a sliding sleeve and a lifting platform for coordinated use, which is convenient for workers to take and store goods on storage tables at different heights. There is no need for workers to borrow other lifting tools or ladders for auxiliary work. It is easy to operate and use, and can effectively improve the practicality and functionality of the overall device structure. By arranging an anti-slip pad on the lifting platform for coordinated use, it is convenient to improve the anti-slip performance and stability, which is convenient for better and safer work.

[0004] In combination with the above-mentioned disclosed technical solution, since manual labor is required to pick up the goods during unloading, and the existing storage cargo stacking devices are generally high, the risk of manual picking is relatively high, which may cause injuries to workers. In addition, the weight of the goods varies and it is difficult for manual labor to carry them, resulting in reduced work efficiency. Therefore, we propose a cargo stacking device for cold chain warehousing to solve this problem. Utility Model Content

[0028] A rotating rod 16 drives the first bevel gear set 11 to rotate, and one end of the rotating rod 16 is fixedly connected to the output end of the motor 17. Both sides of the surface of the rotating rod 16 are rotatably connected to the first screw rod 4 that drives the U-shaped placement plate 2 to move through the first bevel gear set 11. The first bevel gear set 11 includes two first bevel gears, one of which is fixedly connected to one end of the rotating rod 16, and the other is fixedly connected to the surface of the first screw rod 4. The two first bevel gears are meshed with each other, and the two ends of the first screw rod 4 are rotatably connected to the installation box 1 and the U-shaped frame 3 respectively.

[0029] A U-shaped placement plate 2 is used to place goods to be stored. The inner side of the U-shaped placement plate 2 is fixedly connected with a limit rod 13 for limiting the movement of the extrusion block 14. The limit rod 13 passes through the inner wall of the extrusion block 14. The U-shaped placement plate 2 is threadedly connected to the surface of the first screw rod 4. One side of the inner wall of the U-shaped placement plate 2 passes through a rotating column that drives the second bevel gear set 10 to rotate. A knob is installed at one end of the rotating column. One end of the rotating column is rotatably connected to the second screw rod 12 that drives the extrusion block 14 to move through the second bevel gear set 10. The second bevel gear set 10 includes two second bevel gears, one of which is fixedly connected to one end of the rotating column, and the other second bevel gear is fixedly connected to the surface of the second screw rod 12. The two second bevel gears are meshed and connected. The surface of the second screw rod 12 is threadedly connected with the extrusion block 14, and both ends of the second screw rod 12 are rotatably connected to the inner wall of the U-shaped placement plate 2.

[0030] A placing mechanism for placing goods, the placing mechanism includes a storage frame 5 for storing goods which is rotatably connected to the inner wall of the U-shaped frame 3 at equal intervals, both sides of the storage frame 5 are rotatably connected to the U-shaped frame 3 through connecting columns, and a protrusion 15 is fixedly connected to the back of the storage frame 5. The protrusions 15 are tilted sequentially from bottom to top, and the protrusions 15 are located above the extrusion block 14. Both sides of the inner wall of the storage frame 5 are rotatably connected with rollers 6, and the two rollers 6 are connected by a transmission belt transmission. One end of the rotating shaft of one of the rollers 6 is penetrated and arranged in an arc groove provided on the inner wall of the U-shaped frame 3 and is fixedly connected with a limiting gear 8 for driving the roller 6 to rotate, and the side of the limiting gear 8 is meshedly connected with an arc rack 9, and the surface of the storage frame 5 is fixedly connected with a reset rod 7 for resetting the storage frame 5, and the reset rod 7 includes two mounting seats and a spring rod, one of which is fixedly connected to the storage frame 5, and the other mounting seat is fixedly connected to the U-shaped frame 3, both ends of the spring rod are rotatably connected to the mounting seat, and one end of the reset rod 7 is fixedly connected to the inner wall of the U-shaped frame 3.

[0031] The implementation principle of a cargo stacking device for cold chain warehousing in the embodiment of the present application is: the rotating rod is driven to rotate by rotating the knob, the second bevel gear set 10 is driven to rotate by the rotation of the rotating rod, the second screw rod 12 is driven to rotate by the rotation of the second bevel gear set 10, and the extrusion block 14 is driven to move by the rotation of the second screw rod 12, thereby moving the extrusion block 14 to the bottom of the back protrusion 15 of the storage frame 5 where unloading is required.

[0032] The motor 17 is turned on, and the motor 17 drives the rotating rod 16 to rotate, and the rotating rod 16 drives the first bevel gear set 11 to rotate, and the first bevel gear set 11 drives the first screw rod 4 to rotate. Since the two first screw rods 4 are opposite threads, the rotation of the two first screw rods 4 can drive the storage frame 5 to move, and the movement of the storage frame 5 drives the extrusion block 14 to move, so that the extrusion block 14 squeezes the protrusion 15, and the storage frame 5 is flipped under the squeezing of the protrusion 15, and the flipping of the storage frame 5 drives one of the rollers 6 to move. Now the limit gear 8 rotates on the arc-shaped rack 9, and the limit gear 8 drives the roller 6 to rotate. Since one end of the two rollers 6 is fixedly connected to the pulley of the transmission belt, the two rollers 6 can rotate. Due to the use of the arc-shaped rack 9, the two rollers 6 of the storage frame 5 are in a stationary state without flipping, which can prevent the movement of the goods. The rotation of the roller 6 drives the goods on the storage frame 5 to roll onto the U-shaped placement plate 2, and then the motor 17 is reversed, so that the U-shaped placement plate 2 drives the goods to fall. Due to the use of the reset rod 7, the storage frame 5 can be automatically reset.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
