Specifically, when the driving source 44 drives the lifting platform 43 to rise to a set height, the lifting platform 43 docks with the first conveying mechanism 1; when the driving source 44 drives the lifting platform 43 to descend to a set height, the lifting platform 43 docks with the third conveying mechanism 3. The lifting platform 43 also includes a motor for driving the lifting conveyor belt 431 to rotate forward and reverse, thereby realizing the transfer of the material box 100 between the lifting platform 43 and the first conveying mechanism 1 or the third conveying mechanism 3.

[0053] Furthermore, a trumpet-shaped material guide port 432 is provided at the end of the lifting conveyor belt 431 close to the first conveying mechanism 1. Specifically, a bending plate 434 is provided on opposite sides of the lifting conveyor belt 431 perpendicular to its conveying direction, and a trumpet-shaped material guide port 432 is formed between the two bending plates 434.

[0054] Further, a stopper 433 for blocking the movement of the material box 100 is provided on the lifting platform 43. A buffer pad is provided on one side of the stopper 433 close to the material box 100, so as to buffer the impact force on the material box 100 while blocking the movement of the material box 100.

In the above structure, the photoelectric sensor 13 is used to detect the position of the material box 100, so that the device can be operated automatically; the photoelectric sensor 13 and the material box 100 are separated by the first material stopper plate 12, so that the material box 100 is prevented from hitting the photoelectric sensor 13, so that the photoelectric sensor 13 can work reliably for a long time.
