When the material dropping drive assembly 98 drives the receiving racks 95 to rotate on the baffles 9, the distance between the two receiving racks 95 gradually increases, so that the receiving racks 95 can drop the stacked cartons from the bottom until they fall into the guide rails below the receiving racks 95. On the slide rail 96, when the receiving rack 95 drops some cartons onto the guide slide rail 96, the dropping drive assembly 98 drives the receiving rack 95 to reset and continue to receive the cartons located above; and the gap between the receiving rack 95 and the guide slide rail 96 can only accommodate a small number of cartons, which is convenient for the carton opener to remove the cartons, greatly improving the working stability and work efficiency of the carton opener; and a large number of cartons can be stored in the storage box mechanism, so there is no need for workers to frequently fill a small number of cartons, effectively reducing labor costs.

[0045] The horizontal carton opener also includes a detection sensor for detecting the amount of cartons carried by the guide rail 96, and a controller coupled to the detection sensor and capable of controlling the opening and closing of the blanking drive assembly 98. When the detection sensor detects that the amount of cartons carried by the guide rail 96 is less than the set value, the controller can drive the blanking drive assembly 98 to drive the receiving frame 95 to rotate and drop the materials; the detection sensor can detect whether the cartons carried by the guide rail 96 are less than the set number. When the detection sensor detects that the cartons carried by the guide rail 96 are less than the set number, the controller can drive the receiving frame 95 to rotate and drop the materials by starting the blanking drive assembly 98. This design greatly improves the intelligence of the carton opener, which is conducive to further improving the working stability and work efficiency of the carton opener. The detection sensor can be a photoelectric detector, and can be located between the receiving frame 95 and the guide rail 96. The height of the photoelectric detector is the detection height.

The feeding lever 97 is located between the two baffles 9 and can abut against the third side of the carton, which can not only further improve the neatness of the stacked cartons, but also effectively prevent the carton stack from tipping to the side of the feeding lever 97. It can also cooperate with the guide rail 96 to adjust the size of the feeding gap to adapt to the thickness of cartons of different specifications, thereby adjusting the stability of the feeding carton. The above-mentioned locking structure can be a locking screw screwed on the carton opener frame 1. After tightening the locking screw, the feeding lever 97 can be locked on the carton opener frame 1. Furthermore, since the feed stopper 97 can be in direct contact with the carton, installing the detection sensor on the feed stopper 97 can facilitate the detection operation.

The cartons received by the plate 952 fall downward, and the two receiving rods 953 on the two baffles 9 will rotate accordingly and the distance between the two will gradually decrease until the receiving rods 953 are inserted into the carton pile, thereby limiting the falling of cartons. The structure is cleverly designed so that when the receiving frame 95 drops materials, only the cartons located between the receiving plate 952 and the receiving rods 953 can be dropped. This can effectively prevent a large number of cartons received by the receiving frame 95 from falling onto the guide rail 96, and can also keep the number of cartons dropped onto the guide rail 96 each time consistent, which is beneficial to improving the feeding stability of the carton opener.
