[0028] As shown in the figure, the bag handle connecting mechanism of the paper bag machine disclosed in the present invention includes a gluing device, a paper tape compounding device and a bag handle bending device. The gluing device includes a glue storage box 10, a glue strip 8 and a gluing platform 7 matched therewith. The glue strip 8 can move left and right and up and down after being connected to the first driving component. In this embodiment, the first driving component includes a first driving motor 1 and a transmission arm 11. The first driving motor 1 is connected to the first transmission wheel 3 through a transmission belt 4. The first transmission wheel 3 is connected to the second transmission wheel 5. The transmission arm 11 is eccentrically hinged to the first transmission wheel 3 and the second transmission wheel 5, and the glue strip 8 is connected to the transmission arm 11. A glue roller 9 is rotatably arranged at the upper opening of the glue storage box 10. The second transmission wheel 5 is connected to the fourth transmission wheel 6 in transmission connection, and the fourth transmission wheel 6 is connected to the rubber roller 9. As the first driving motor 1 moves, the first and second transmission wheels can be driven to rotate, and at the same time, the transmission arm 11 and the upper glue strip 8 are driven to move to the rubber roller 9 to dip a certain amount of glue, and then move to the glue application platform 7. At this time, the paper bag substrate has been transported to the upper platform 7. The transportation mechanism of the paper bag substrate belongs to the prior art and is not the innovation of this application, so it will not be repeated. Then the upper glue strip 8 applies glue to the bag handle bonding part of the paper bag substrate. A paper tape unwinding component and a paper tape cutting component are arranged on one side of the glue application platform 7. The paper tape unwinding component includes an unwinding seat 2, and the rolled paper tape is placed on the unwinding seat 2 for unwinding. The paper tape cutting component includes a cutting knife 13, a knife seat 31 matched with the cutting knife 13, and a driving cylinder 12. One end of the cutting knife 13 is hinged on the frame 14, and the piston rod of the driving cylinder 12 is hinged with the cutting knife 13. By controlling the driving cylinder 12, the cutting knife 13 can be driven to swing and cooperate with the knife seat 31, thereby realizing the cutting of the paper tape. A material trough 15 is provided at the discharge end of the paper tape cutting assembly, and a paper tape compounding device and a bag handle bending device are provided below the corresponding material trough 15. Baffles 16 are provided on the left and right sides of the material trough 15 to prevent the paper tape from deviating. Baffles 32 are provided on the baffles 16 to support the cut paper tape and prevent the paper tape from falling directly from the material trough 15, waiting for the paper tape compounding device to absorb the paper tape. Specifically, the paper tape composite device includes a suction cup 25, a lifting seat 23, a rotating shaft 21 and a clamping platform 24 cooperating with the suction cup 25. The rotating shaft 21 is rotatably arranged on the lifting seat 23, and its two ends are rotatably placed in the limit groove 20. The limit groove 20 is "S" shaped and is arranged on the guide plate 18. Specifically, the two ends of the rotating shaft 21 are connected with guide blocks 22, and the guide block 22 is eccentrically provided with a guide shaft 30. The guide shaft 30 is penetrated in the limit groove 20, and the guide shaft 30 is connected with a bearing 19, so that it can move more smoothly in the limit groove 20. When the lifting seat 23 lifts and lowers with the rotating shaft 21, the guide block 22 rotates driven by the limit groove 20, thereby driving the rotating shaft 21 and the suction cup 25 to flip up and down.The suction cup 25 is connected to the rotating shaft 21, and the lifting seat 23 is connected to the lifting drive assembly. Specifically, the lifting drive assembly includes a second driving motor 17, which is connected to the third transmission wheel 29, which is connected to the second transmission belt 28, and the second transmission belt 28 is connected to the lifting seat 23. By controlling the second driving motor 17 to drive the second transmission belt 28 to move, the lifting seat 23 and the suction cup 25 can be driven to lift. Of course, in addition to the above structure, the lifting seat 23 can also be connected to common driving components such as cylinders, linear motors, and ball screws to achieve its lifting. The rotating shaft 21 is connected to an elastic plate 26, and a clearance groove is provided on the elastic plate 26 for the suction cup 25 to pass through. Ensure that the elastic plate 26 can completely squeeze the paper tape, and then compact the paper tape on the paper bag substrate, and adhere and cover the adhesive part of the bag handle. The bag handle bending device includes a clamping block 34 arranged at intervals on the left and right, and the clamping block 34 is connected to a lifting power assembly, which can be a cylinder, an oil cylinder, etc. A rotating body 35 is arranged below the clamping block 34, and the rotating body 35 is connected to the rotating power assembly, which can be a conventional motor.

[0029] According to the structure of the present invention, when the paper bag base material and the bag handle are sent to the gluing platform 7, the first driving motor 1 drives the transmission arm 11 to move, drives the gluing strip 8 to move to the glue roller 9 to dip a certain amount of glue, and then moves to the gluing platform 7 to dip the glue in the bonding part of the bag handle of the paper bag base material. Then, as the paper bag base material is transported, the paper bag base material is sent to the pressing platform 24, and the paper tape is driven by the paper tape unwinding assembly to move to the cutting knife 13 to be cut. At this time, the second driving motor 17 is activated to drive the lifting seat 23 to rise, and at the same time, the limiting groove 20 drives the rotating shaft 21 to rotate upward, drives the suction cup 25 to flip upward and absorb the cut paper tape from the material trough 15, then the second driving motor 17 is reversed, drives the lifting seat 23 to descend, and at the same time, the limiting groove 20 drives the rotating shaft 21 to rotate downward, drives the suction cup 25 to flip downward, and finally the suction cup 25 moves to the paper bag base material at the pressing platform 24. At this time, the rolled bag handle is unwound along with the bag handle unwinding rack 33, and is cut by the cutting mechanism, and is sent to the position close to the pressing platform 24 under the drive of the conveying mechanism. At this time, the pressing block 34 in the bag handle bending device descends, and the cut bag handle is pressed tightly between the pressing block 34 and the rotating body 35. Then the rotating body 35 rotates, the bag handle is bent, and the two ends of the bag handle just extend into the pressing platform 24 and are located above the paper bag substrate. The unwinding, cutting and conveying mechanism of the bag handle is the same as the structure of the non-woven fabric handle ironing machine, belongs to the prior art, and has nothing to do with the innovation of the present application, so it will not be repeated. Then the suction cup 25 releases the paper tape, so that the paper tape falls to the adhesive of the paper bag substrate and covers the two ends of the bag handle. Finally, the lifting seat 23 descends a certain distance again, so that the elastic plate 26 can completely press the paper tape on the paper bag substrate and the adhesive of the bag handle, and cover the paper bag handle to stick the paper tape firmly.

[0030] The invention has a simple structure and a reasonable design, and can automatically realize the gluing operation of the paper bag base material and the bag handle. After the gluing is completed, the paper tape is pasted on the paper bag base material to cover the bonding part of the bag handle, thereby ensuring the bonding stability and reliability of the bag handle.
