Fruit cup stacking device

The invention relates to the technical field of automatic arrangement devices, in particular to a fruit cup stacking device. The fruit cup stacking device comprises a flat conveying belt, and a feeding conveying belt is arranged on the upper portion of one side of the flat conveying belt. Conveying screw rods are mounted on one side of the front end of the feeding conveying belt in parallel, a rotary shaft is arranged above the feeding conveying belt, and a plurality of front slideways and a plurality of rear slideways are mounted on the two sides of the feeding conveying belt respectively. Through linkage of the front slideways, the rear slideways and a cup shifting plate, fruit cups can be separated to be conveyed, the forward fruit cups and the backward fruit cups can be distinguished, the structure is simple, and efficiency is high. The fruit cups are conveyed through the reducing variable-pitch screw rod, and it is guaranteed that the interval between the fruit cups moving on the feeding conveying belt is consistent with that between the front slideways and the rear slideways, and the fruit cups smoothly enter inlets of the front slideways and inlets of the rear slideways. The inlets of the front slideways are connected with hinges, outlets of the front slideways are connected with lifting mechanisms, and stable running of the fruit cups on the flat conveying plate is guaranteed.
