DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] like Figure 1 and Figure 2 As shown, a carton turning device for nailing cartons includes a frame, a conveying structure is arranged on the frame, the conveying structure is a conveyor belt structure, the conveyor belt of the conveyor belt structure includes two groups of conveyor belt bodies 1 arranged at intervals, and a flipping structure 3 is also arranged on the frame, the flipping structure is arranged between the two conveyor belt bodies, the flipping structure includes a bottom plate, the bottom plate includes an upper bottom plate 4 and a lower bottom plate 5, the lower bottom plate is connected to the frame, one end of the upper bottom plate is rotatably connected to the lower bottom plate, a limit plate 6 is provided on the bottom plate, and baffle plates 7 are respectively vertically slidably connected to both ends of the limit plate, and the length direction of the limit plate is the same as the conveying direction of the carton.

[0013] Furthermore, the conveyor belt structure includes two sets of transmission shafts 2 arranged opposite to each other, and the transmission shafts are connected to the frame through bearings. Two sets of transmission wheels are arranged on each transmission shaft, and the two transmission wheels on the two transmission shafts correspond to each other, and are used for arranging two conveyor belt bodies. The transmission wheels are detachably connected to the transmission shafts, and one of the two transmission shafts is connected to the driving structure.

[0014] The limit plate and the baffles on both sides of the limit plate are provided with two groups, and the two groups of limit plates are arranged at intervals and detachably connected to the upper bottom plate. Specifically, the limit plate can be connected to the upper bottom plate through a connecting plate, which makes it easier to control the area of ​​the upper bottom plate, while also ensuring the adaptability to different cartons.

[0015] Furthermore, a rotating disk 8 is rotatably connected to the frame, and a vertically arranged telescopic cylinder 9 is arranged on the rotating disk, and the upper free end of the telescopic cylinder is connected to the lower bottom plate. The lower bottom plate is a frame plate, including two horizontal plates arranged at intervals, and a plurality of vertical plates are arranged between the two horizontal plates.

[0016] The overall structure is arranged at the lower side of the carton unloading structure to facilitate receiving the unloaded cartons and thus realize the flipping of the cartons.

[0017] Furthermore, guide plates can be added to the frame. There are two groups of guide plates, which are arranged at intervals and are used to guide the cartons when they are turned over to ensure that they fall on the conveyor belt body. When the guide plates are not needed, the guide plates can also be removed.

[0018] The working principle of the present invention is as follows: when the carton needs to be turned over and rotated, the baffle plate close to the feeding side of the carton slides down and the other side moves up. When the carton is conveyed on the conveyor belt body, it presses against the baffle plate, and then the limit plate rotates, and the carton falls on the conveyor belt body after being turned over in a straight line, and continues to be conveyed, thereby realizing the turning over and rotation of the carton; when the carton needs to be rotated in a plane, the bottom plate is lifted up and reset, and the baffle plates on both sides rise and fall in an offset manner, thereby ensuring the transportation of the carton after the plane rotation; when the carton needs to be turned over and rotated in a plane, the bottom plate is first rotated 180°, and then the bottom plate is lifted up to realize the turning, and then the bottom plate is reset, and the action is repeated.

[0019] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
