[0019] like Figure 1-5 As shown, the utility model is a sorting and opening bag mechanism of a secondary bagging machine, including a base 1, on which a whole bag bottom plate 3 is connected via a slider rail structure arranged in a vertical direction, and the whole bag bottom plate 3 is controlled in position by a bottom plate lifting cylinder 2 connected to the base 1.

[0020] The two sides of the packing bottom plate 3 are connected to the packing cylinder 6 through the slider rail structure arranged in the left and right directions. The two packing cylinders 6 are driven by the transverse drive to adjust the distance between them. The push rod ends of the two packing cylinders 6 are respectively fixed with the packing baffles 7 arranged relatively.

[0021] The upper end of the base 1 is fixed with a bag opening suction cup bottom plate 8, on which a baffle lifting cylinder 13 and a lower suction cup 18 are fixed in sequence from front to back, the baffle lifting cylinder 13 is arranged vertically, and the end of the output rod of the baffle lifting cylinder 13 is fixed with a bag front end baffle 14;

[0022] Both sides of the bagging bottom plate 3 are connected with bagging brackets 9 through slider rail structures arranged in the left and right directions respectively. The two bagging brackets 9 move synchronously with the bagging cylinder 6 on the same side. The front end surfaces of the two bagging brackets 9 are fixed with bagging stopper plates 10. The tops of the two bagging brackets 9 are hinged with bagging rotating cylinders 11 and upper bagging sheets 12. The push rod end of the bagging rotating cylinder 11 is connected with the upper bagging sheet 12 and drives the upper bagging sheet 12 to rotate.

[0023] A bag opening arm 16 is provided above the entire bag bottom plate 3. The bag opening arm 16 is connected to the base 1 through a slider rail structure arranged along the vertical direction. The bag opening arm 16 is driven to rise and fall by a bag opening driver. An upper suction cup 17 arranged opposite to the lower suction cup 18 is fixed on the bag opening arm 16.

[0024] The transverse drive includes a baffle adjustment motor 4 and a baffle adjustment screw 5. Both ends of the baffle adjustment screw 5 are rotatably connected to the base 1. The baffle adjustment screw 5 has two threaded parts with different rotation directions. The movable seats fixed at the bottom of the two full-pack cylinders 6 are screwed to the threaded parts with different rotation directions. The bag opening bracket 9 is connected to the movable seat at the bottom of the full-pack cylinder 6 on the same side through a slider rail structure arranged in the vertical direction. Through the above linkage structure, when the baffle adjustment screw 5 rotates, it drives the two relatively arranged full-pack cylinders 6 to move synchronously, and at the same time drives the two bag opening brackets 9 to move synchronously, thereby adjusting the distance between the two sorting and packing baffles 7 and the distance between the two upper bag sheets 12.

[0025] The bag opening driver comprises a bag opening motor 15 and a screw rod, both ends of which are rotatably connected to the base 1 , the bag opening motor 15 drives the screw rod to rotate, and the bag opening arm 16 is transmission-connected to the screw rod through a nut seat.

[0026] The working principle of the utility model (take rice bag as an example):

[0027] ① The initial working state is as follows Figure 1 , 2 As shown in FIG. 3 , the bottom plate lifting cylinder 2 contracts downward to lower the whole bag bottom plate 3 to dock with the rice bag conveyor belt, and the baffle adjustment motor 4 drives the baffle adjustment screw 5 to rotate to adjust the position of the whole bag cylinder 6 so that the distance between the sorting and entering baffles 7 is consistent with the width of the rice bag, and the baffle adjustment screw 5 simultaneously drives the two bag opening brackets 9 to move so that the distance between the upper bag pieces 12 installed on the two bag opening brackets 9 is consistent with the width of the rice bag;

[0028] ② If Figure 2 As shown, the rice bag is sent from the left to the right to the whole bag bottom plate 3 by the rice bag conveyor belt, and the external blowing device is used to ensure that the rice bag is sent to the whole bag bottom plate 3, the bag mouth of the rice bag is bent under the rice bag, and the bag opening stop plate 10 limits the stop position of the rice bag. At this time, the whole bag cylinder 6 extends to make the bag arrangement baffle 7 to adjust the center position of the rice bag to prepare for bag entry, and the lifting cylinder 2 extends to lift the whole bag bottom plate 3 with the rice bag with the corrected center position, and the bag mouth is aligned with the front end baffle 14 of the bag and placed, and then the bag is opened. The bag motor 15 drives the bag opening arm 16 to descend so that the upper suction cup 17 and the lower suction cup 18 clamp the bag opening. After the external vacuum source works, the bag opening motor 15 drives the bag opening arm 16 to ascend so that the upper suction cup 17 and the lower suction cup 18 suck the bag opening together. The baffle lifting cylinder 13 contracts to lower the baffle 14 at the front end of the bag. The bag opening rotating cylinder 11 contracts to extend the upper bag sheet 12 into the opening and then open the bag. At the same time, the rice bag is pushed to the next station from the right side by the robot arm after the upper bag sheet 12.

[0029] ③ If Figure 5 As shown, the whole bag bottom plate 3 is extended and lifted by the bottom plate lifting cylinder 2 to be slightly higher than the bag opening suction cup bottom plate 8 to prevent the rice bag from colliding during movement. At this time, the external manipulator intervenes to push the rice bag from left to right into the bag opened by the upper bag piece 12, and then continues to move to the right to send the rice bag with the outer bag to the next workstation, and then reciprocates.

[0030] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
