[0028] The working principle and use process of the utility model are as follows: the multi-axis mechanical arm 3 moves to the sheet carton storage position, and is accurately positioned above the carton through the movement flexibility thereof, in the opening box mechanism 4, the supporting frame 41 fixed at the output end of the multi-axis mechanical arm 3 plays a supporting role, so that the opening box frame 42 remains stable, the motor 43 is started, the gear 44 at the output end of the motor 43 starts to rotate, since the gear 44 is meshed with the two toothed plates 45 on the two sides, the rotation of the gear 44 drives the two groups of toothed plates 45 to move in opposite directions, the opening box plates 46 fixed on the opposite sides of the toothed plates 45 can only stably slide along the sliding rod direction under the limitation of the limiting sliding rods 47, so that the two groups of opening box plates 46 are gradually separated, at this time, the multi-axis mechanical arm 3 adjusts the position, aligns the plurality of groups of opening box suction cups 48 on the opening box plates 46 with the sheet carton, at the same time, the opening box suction cups 48 on the opposite side of the opening box plates 46 are externally connected with the air suction pump (not shown in the figure) through the gas conveying pipe, the air suction pump generates negative pressure in work, so that the opening box suction cups 48 adsorb the two sides of the sheet carton, with the separation of the opening box plates 46, the carton is gradually opened to form a box shape, then the multi-axis mechanical arm 3 drives the opening box mechanism 4 with the adsorbed carton to move to the specified position above the conveyor 1, and the opening box process is completed.
[0029] Further, after the box is opened, the two groups of push-pull air cylinders 21 are started, the folding frame 22 is pushed by the two groups of push-pull air cylinders 21 to move along the surface of the guide rail 23 towards the position of the carton, so that the folding frame 22 covers the folding edge of the carton, until the folding frame 22 surrounds the carton, at this time, the longitudinal air cylinders 24 on the upper and lower sides of the folding frame 22 are preferentially extended, and the longitudinal folding pressing plates 25 at the output ends of the longitudinal air cylinders 24 move downward or upward, so that the upper and lower sides of the carton are folded, then the transverse air cylinders 26 on the left and right sides of the folding frame 22 are extended, and the transverse folding pressing plates 27 at the output ends of the transverse air cylinders 26 move towards the middle, so that the left and right sides of the carton are folded, and the automatic folding and shaping of the carton are realized through the cooperative action of the longitudinal air cylinders 24 and the transverse air cylinders 26.
[0030] Further, in the process of moving the folding frame 22 along the surface of the guide rail 23 towards the position of the carton, the two groups of transverse folding pressing plates 27 attached to the surface of the glue applying roller brush 214 are synchronously moved by the movement of the folding frame 22, at this time, the glue applying machine (not shown in the figure) sprays glue onto the surface of the glue applying roller brush 214 in the glue applying sleeve 213 through the glue spraying pipe 215, and in the process of relative movement of the glue applying roller brush 214 and the transverse folding pressing plate 27, the positioning sliding sleeve 211 on the surface of the positioning sliding rod 210 is driven by the spring 212, so that the glue applying roller brush 214 can tightly adhere to the surface of the transverse folding pressing plate 27, so that the glue applying roller brush 214 rotates along the surface of the transverse folding pressing plate 27, thereby applying glue to the surface of the transverse folding pressing plate 27, and the transverse folding pressing plate 27 with the applied glue will adhere glue to the surface of the left and right sides of the carton in the folding action of the left and right sides of the carton, so that the upper and lower sides and the left and right sides of the carton are bonded, thereby ensuring firm bonding of the folding part of the carton.
[0031] It is worth noting that after the folding and glue applying of the carton are completed, the air suction pump is controlled to stop working, the opening box suction disc 48 loses the adsorption force, the adsorption and fixation of the carton are released, then the discharging air cylinder 216 is started, the discharging push plate 217 driven by the discharging air cylinder 216 pushes the carton whose folding and glue applying are completed out of the two groups of opening box suction discs 48, so that the carton falls onto the conveyor 1 and is conveyed to the next process.
