[0038] See also Figure 1 The top of the carton 101 has four sides, which are the first long side 101, the first short side 102, the second long side 103 and the second short side 104 in sequence; before sealing the carton 101, the first short side 102 and the second short side 104 need to be folded in half and pressed down first, and then the first long side 101 and the second long side 103 are pressed on the first short side 102 and the second short side 104, so that the tape can seal the top of the carton 101.

[0039] See also Figure 2 , Figure 3, the carton 101 containing the Sun Ink product is transported to the bottom of the paper pressing assembly through the conveyor line 1, and the carton 101 is transported along the conveyor line 1 along the first direction, so that the first short side 102 of the carton 101 near the discharge port of the conveyor line 1 is first pressed down by the paper pressing assembly, and then the paper pressing assembly presses down the second short side 104 of the carton 101 near the feed port of the conveyor line 1, and finally, the first long side 101 and the second long side 103 of the carton 101 are synchronously pressed on the first short side 102 and the second short side 104 of the carton 101, so as to realize the folding of the four side sides of the top of the carton 101, so as to facilitate the tape to seal the top of the carton 101. Through this arrangement, the packaging efficiency of the carton 101 containing products can be improved and the labor cost can be reduced.

[0040] In one or more embodiments, the paper pressing assembly includes at least: a keel 31, the keel 31 is configured to move in a vertical direction on the material rack 2, a pressing structure 32 is formed at the bottom end of the keel 31, and the pressing structure 32 can press down the short side of the carton 101 close to the discharge port of the conveyor line 1; a rotating pressing structure 33, the rotating pressing structure 33 is installed on the keel 31, the rotating pressing structure 33 is located at the feed port of the conveyor line 1 relative to the pressing structure 32, and the rotating pressing structure 33 can press down the short side of the carton 101 close to the feed port of the conveyor line 1; a side clamping structure 34, the side clamping structure 34 is configured on the side of the keel 31 in the second direction, and is used to press the two opposite long sides of the carton 101 onto the two short sides of the carton 101.

[0041] See also Figures 2 to 5 The pressing structure 32 is on the keel 31 relatively close to the discharge port of the conveyor line 1, and the pressing structure 32 is used to press the first short side 102 of the top of the carton 101 close to the discharge port of the conveyor line 1; the rotating pressing structure 33 is on the keel 31 relatively close to the feed port of the conveyor line 1, and the rotating pressing structure 33 is used to press the second short side 104 of the top of the carton 101 close to the feed port of the conveyor line 1; the side pressing structure 34 is located on both sides of the keel 31 in the second direction, and the side pressing structure 34 can synchronously press the first long side 101 and the second long side 103 opposite to the top of the carton 101 onto the first short side 102 and the second short side 104.

[0042] When the carton 101 is sealed and packed, the conveyor line 1 is first used to control the carton 101 to move in the first direction, so that the first short side 102 of the top of the carton 101 is relatively located at the discharge port of the conveyor line 1, and the second short side 104 is relatively located at the feed port of the conveyor line 1. At the same time, the driving cylinder connected to the keel 31 controls the keel 31 to move downward, so that the pressing structure 32 moves down to the top of the carton 101. Since the carton 101 passes through the pressing structure 32 when moving with the conveyor line 1, and the pressing structure 32 is lower than the height of the first short side 102 of the carton 101, the first short side 104 of the carton 101 is The side 102 can be bent downward, and then the rotating pressing structure 33 is controlled to bend the second short side 104 of the carton 101, and then the side clamping structure 34 is used to simultaneously apply pressure to the first long side 101 and the second long side 103 of the carton 101, so that the first long side 101 and the second long side 103 of the carton 101 are pressed against the first short side 102 and the second short side 104, thereby bending the four side sides of the top of the carton 101, which is convenient for the subsequent adhesive tape to bond the carton 101.

Through this arrangement, the first long side 101 and the second long side 103 of the carton 101 will not contact the bottom of the keel 31 after bending, thereby avoiding the problem that the keel 31 hinders the bending of the first long side 101 and the second long side 103 of the carton 101, avoiding interference with equipment operation, and improving the use effect of the present application.

[0046] In one or more embodiments, a polished rod 4 is vertically arranged on the conveyor line 1, and the polished rod 4 passes through the keel 31 to limit the keel 31 to move only in the vertical direction. Figure 3 The keel 31 is restricted by the vertical light rod 4 to move only in the vertical direction, thereby improving the accuracy of the vertical movement of the keel 31.

[0047] In one or more embodiments, a limit centering component is arranged at the feed port of the conveyor line 1, and the limit centering component can push the carton 101 along the second direction so that the carton 101 can be conveyed by the conveyor line 1 along the first direction to directly below the paper pressing component; the limit centering component includes at least a first limit unit and a second limit unit symmetrically arranged on both sides of the feed port of the conveyor line 1; the first limit unit or the second limit unit includes a limit plate 5 and a third driving device for controlling the movement of the limit plate 5 along the second direction.

[0048] See also Figure 2 , Figure 3 The first limiting unit and the second limiting unit have the same structure; the third driving device can be a driving cylinder. The third driving devices of the first limiting unit and the second limiting unit synchronously push the limiting plates 5 connected thereto, so that the carton 101 between the two limiting plates 5 can be centered and limited, so that the carton 101 can be conveyed by the conveyor line 1 to the right below the keel 31, thereby improving the paper pressing efficiency of the carton 101.

[0049] In one or more embodiments, the limiting plate 5 is bent toward the outside of the conveying line 1 at the end away from the paper pressing assembly. Figure 2 The two limit plates 5 are simultaneously bent toward the outside of the conveyor line 1 to form a trumpet shape. Through this arrangement, the carton 101 can be guided to speed up the conveying efficiency of the carton 101.
