Wherein, the sliding platform 512 can also be driven by a motor screw to realize transportation, which is selected according to actual usage requirements. In this embodiment, the cooperation of the gear and the rack 120 can effectively improve the delivery force.

Referring to FIG. 2 again, it should be noted that, in this application, since the first pushing device 500 needs to go down through the conveying device 400 and hook the uppermost plate of the first palletizing rack 210 during use, and The second pushing device 600 only needs to reciprocate and push the uppermost plate of the second pallet rack 310. For this reason, the second pushing device 600 in this application can use the above-mentioned walking mechanism 510 and the lower pressing seat 525 to cooperate, that is, press down The seat 525 is directly installed on the running gear 510, the overall structure is more simplified, and the requirements of the work are also met.

The above-mentioned embodiment is only a preferred embodiment of the present invention, and cannot be used to limit the protection scope of the present invention. Any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of the present invention. Scope of protection claimed.
