[0019] Beneficial effects:

[0020] The present invention provides a high-efficiency storage bin structure with lifting mechanism. By setting up a material rack lifting mechanism, when the first pulley rotates and the transmission belt moves along the first pulley, the second storage rack can be lifted and moved up and down within the second storage area.

A first servo motor can control the rotation of a threaded rod. By setting a first guide wheel, a connecting frame can move on the side wall of a first guide rail. At the same time, the connecting frame can only move vertically up and down on the side wall of the first guide rail, thereby limiting the direction of movement of the compartment door and preventing the compartment door from rotating. By movably connecting a movable frame to the side wall of the threaded rod, the rotation of the threaded rod can drive the compartment door on one side of the movable frame to move up and down, thereby controlling the opening and closing of the compartment door.

[0023] The present invention provides a high-efficiency storage bin structure with lifting mechanism. A support spring is provided to support the pad, so that the material can be more gently and stably supported when placed in the second storage rack. By setting a limit block, the second storage rack can only move up and down along the side wall of the second guide rail, thereby limiting the movement direction of the second storage rack and providing a certain support function when storing materials in the second storage rack.

[0042] Material rack lifting mechanism 5 is installed inside the second storage area 3. Material rack lifting mechanism 5 is used to control the lifting of the second storage rack 51, thereby adjusting the height of the second storage rack 51.

[0043] The outbound mechanism 6 is located in the second storage area 3 and is used to push the materials in the second storage area 3 out of the warehouse.

[0044] The material rack lifting mechanism 5 includes a second servo motor 501, a first transmission wheel 502, a transmission belt 503, a rotating rod 504, a second transmission wheel 5041, a first pulley 5042, and a transmission belt 505.

The first connecting piece 5051 and the second connecting piece 511 are fixedly connected.

[0045] In this embodiment, the second storage rack 51 is installed on one side of the transmission belt 505 via the first connector 5051 and the second connector 511. When the first pulley 5042 rotates and the transmission belt 505 moves along the first pulley 5042, the second storage rack 51 can move up and down within the second storage area 3. By setting the second servo motor 501, the rotation of the first transmission wheel 502 can be controlled. The rotation of the first transmission wheel 502 can drive the second transmission wheel 5041 and the rotating rod 504 to rotate via the transmission belt 503. The rotation of the rotating rod 504 can drive the first pulley 5042 to rotate, thereby allowing the transmission belt 505 to move along the side wall of the first pulley 5042.

[0046] In one embodiment, a second pulley 506 is rotatably connected to the inner wall of the second storage area 3, and a fixing frame 507 is fixedly installed on the inner wall of the second storage area 3.

The two first pulleys 5042 are connected to the second pulley 506 and the third pulley 5061 respectively through the two transmission belts 505.

[0047] This embodiment is provided with two first pulleys 5042 and two transmission belts 505, so that when the rotating rod 504 rotates, it can drive the second pulley 506 and the third pulley 5061 to rotate simultaneously through the two first pulleys 5042, so that the first connecting piece 5051 on the side wall of the two transmission belts 505 can move together, thereby making the second storage rack 51 more stable when it moves up and down.

[0048] In one embodiment, a groove 514 is provided inside the second storage rack 51, and a plurality of support springs 515 are fixedly installed on the inner wall of the groove 514.

The limit block 512 is slidably connected to the inside of the second guide rail 508.

[0049] In this embodiment, a support spring 515 is provided to support the pad 513, so that the material can be more gently and stably supported when placed in the second storage rack 51. By setting a limit block 512, the second storage rack 51 can only move up and down along the side wall of the second guide rail 508, thereby limiting the movement direction of the second storage rack 51 and providing a certain support when the second storage rack 51 stores materials.

[0050] In one embodiment, a plurality of storage plates 201 are fixedly installed inside the first storage area 2, and a first storage rack 301 is fixedly installed on the inner wall of the second storage area 3.

[0053] In this embodiment, a first servo motor 402 is provided to control the rotation of the threaded rod 403. By providing a first guide wheel 4071, the connecting frame 407 can move on the side wall of the first guide rail 406. At the same time, the connecting frame 407 can only move vertically up and down on the side wall of the first guide rail 406, thereby limiting the direction of movement of the door 401 and preventing the door 401 from rotating. By movably connecting the movable frame 404 to the side wall of the threaded rod 403, the rotation of the threaded rod 403 can drive the door 401 on one side of the movable frame 404 to move up and down, thereby controlling the opening and closing of the door 401.

[0057] In this embodiment, a third servo motor 603 is provided, which can drive one of the second guide wheels 602 to rotate. The rotation of the second guide wheel 602 can drive the moving frame 601 to move on one side of the third guide rail 604, thereby controlling the movement of the moving frame 601. By providing a push plate 605 on one side of the moving frame 601, the push plate 605 can push the material on one side during the movement of the moving frame 601, pushing the material from inside the second storage area 3 to outside the second storage area 3, thereby enabling rapid material conveying.
