[0029] In the above structure, two opposite sides of the silo 1 are provided with a carton anti-fool plate 10, one end of the carton anti-fool plate 10 extends into the silo 1, and the end of the carton anti-fool plate 10 extending into the silo 1 is arranged opposite to the opening position of the carton. In a specific embodiment, the end of the carton anti-fool plate 10 extending into the silo 1 is pointed, and a triangular opening structure is provided on the folding carton, and the opening area of ​​the triangle is larger than the area of ​​the sharp corner of the carton anti-fool plate 10. When the folding carton is placed in the silo 1, the sharp corner of the carton anti-fool plate 10 just passes through the carton anti-fool plate 10 and extends to the end of the carton in the silo 1, which can prevent the carton from being placed in the wrong direction in the silo 1, making it difficult to unfold the carton when the carton picking assembly 2 stretches the carton.

[0030] Reference Figure 2 As shown, the silo 1 includes a plurality of silo support columns 11, a carton receiving plate 12 and a carton limiting rod 13. The carton receiving plate 12 is fixedly mounted on the plurality of silo support columns 11. The lower end of the carton limiting rod 13 is mounted on the carton receiving plate 12.

[0031] Reference Figure 3 As shown, a plurality of paper box support plates 15 are installed on the paper box receiving plate 12, one end of the paper box support plates 15 extends to the cross-sectional range of the rectangular through hole 14, and the plurality of paper box support plates 15 are used to support the paper box. A preferred embodiment is that the plurality of paper box support plates 15 are arranged in four, and the four paper box support plates 15 are all in the shape of rectangular thin plates with the same structure, and the four paper box support plates 15 are located at the qualified corner positions of the rectangular cross-section.

[0032] In the above structure, two symmetrically arranged anti-fool plates 10 are installed on the paper box receiving plate 12, and one end of the paper box anti-fool plates 10 extends to the cross-sectional range of the rectangular through hole 14. The setting position of the paper box anti-fool plates 10 is specifically set according to the structure of the paper box. In one embodiment, triangular openings are provided at the two relative short sides of the rectangular paper box, so the paper box anti-fool plates 10 are provided at the symmetrical positions of the two short sides of the rectangular through hole 14. The paper box limiting rod 13 is a cylindrical rod, and a U-shaped connecting plate 16 is provided at the upper end of a part of the paper box limiting rod 13, and the two opposite sides of the U-shaped connecting plate 16 are provided with a paper box anti-fool plates 10, so that when the paper box is placed in the silo surrounded by a plurality of paper box limiting rods 13, the way and position of the paper box have been determined to prevent the paper box from being placed in the wrong direction.

[0033] Reference Figure 4 , 5As shown, the paper box picking assembly 2 includes a picking support seat 21, a picking cylinder 22, a plurality of picking nozzles 23 and a nozzle mounting plate 24, the picking cylinder 22 is fixedly mounted on the picking support seat 21, and the piston rod of the picking cylinder 22 is connected to the nozzle mounting plate 24, the plurality of picking nozzles 23 are arranged on the nozzle mounting plate 24, and the plurality of picking nozzles 23 are used to absorb the paper boxes at the bottom of the silo 1.
