As shown in fig. 1-3, a foam box feeding device for an incinerator comprises a rotary kiln 100, an upper conveying device 200, a lower conveying device 300 and a lifting device 400, wherein the discharge end of the upper conveying device is positioned outside a feed inlet of the rotary kiln; the lifting device 400 includes a plurality of carrying boards 420 driven by two groups of chains 410 to move synchronously, the carrying boards 420 are in a chain structure formed by hinging a plurality of boards, the front and the back of the carrying boards 420 are respectively connected to the two groups of chains 410, the two groups of chains 410 are provided with a lifting section 411 and a descending section 412 which are arranged vertically and a feeding horizontal section 413 which is arranged horizontally, the feeding horizontal section is connected with the lifting section, and the lifting sections of the two groups of chains are arranged in tandem and have the same interval distance with the width of the carrying boards so that the carrying boards are in a horizontal state in the lifting section; according to the utility model, the material carrying plate with the chain plate structure is adopted, so that the material carrying plate can be bent and synchronously move along with the chains, and meanwhile, the material carrying plate can be pulled to a horizontal state in the lifting sections and the feeding horizontal sections of the two groups of chains, so that the foam box is placed, and the foam box is ensured to be stably fed and lifted; the feeding device can realize the vertical lifting of the foam box, has small overall occupied space, strong practicability and stable operation, and avoids the condition that the foam box slides down or falls down.

In this embodiment, both the upper conveying device and the lower conveying device employ a chain conveyor.

In this embodiment, the front end position of the feeding horizontal segment of the chain is provided with an infrared sensor for sensing the carrying plate, but when sensing that the carrying plate bends upwards from the bottom of the chain to the feeding horizontal segment, the lower conveying device simultaneously sends the foam box into the carrying plate, and the movement speed of the lower conveying device is consistent with that of the carrying plate.
