The transport device 56 here corresponds in practice to the structure of the after-feeder 9.

The packaging bag sealing and code spraying device 4 comprises a bag receiving structure 82, a discharging machine 83, a sealing structure 84 and a code spraying structure 85, wherein the bag receiving structure 82 comprises a bag receiving cylinder 86 and a bag receiving assembly 87, the bag receiving cylinder 86 pushes the bag receiving assembly 87 to move, and the bag receiving assembly 87 is made to reciprocate between the rear opening device 60 and the discharging machine 83; the discharging machine 83 is provided with a front holder 88 and a rear holder 89, and the distance between the front holder 88 and the rear holder 89 is equal to the distance between the sealing structure 84 and the code spraying structure 85.

The sealing structure 84 and the code spraying structure 85 are conventional sealing machines and code spraying machines on the market, and detailed description thereof is omitted here.

Connect bag subassembly 87 including lift cylinder 90, with the revolving cylinder 91 that lift cylinder 90 is connected and connect revolving cylinder 91's finger cylinder 92, have two vaulting poles 93 on the finger cylinder 92, two vaulting poles 93 are used for transversely strutting wrapping bag 7. Through the combined action of the bag receiving cylinder 86 and the lifting cylinder 90, the two support rods 93 of the finger cylinder 92 are placed in the packaging bag 7, and under the action of the finger cylinder 92, the two support rods 93 are supported at the two sides of the width direction of the inner wall of the packaging bag 7 along the width direction of the packaging bag 7, then the rotating cylinder 91 works to rotate the packaging bag 7 by 90 degrees, so that the width direction of the packaging bag 7 is parallel to the sealing structure 84, and the front surface of the packaging bag 7 is perpendicular to the code spraying structure 85.

The discharging machine 83 comprises a servo motor 94, a driving wheel 95, a driven wheel 96 and a belt 97, the servo motor 94 drives the driving wheel 95 to rotate, the belt 97 is sleeved between the driving wheel 95 and the driven wheel 96, and the front clamp holder 88 and the rear clamp holder 89 are respectively fixed on the belt 97.

The front clamp 88 includes a front clamp cylinder 98, a fixed clamp plate 99 and a movable clamp plate 100, and the front clamp cylinder 98 drives the movable clamp plate 100 to move relative to the fixed clamp plate 99, so that the movable clamp plate 100 and the fixed clamp plate 99 cooperate to clamp or release the packing bag 7.

The rear clamp 89 includes a rear clamp cylinder 101, and two clamp arms 103 connected to a clamp rod 102 of the rear clamp cylinder 101.

After the bag receiving structure 82 rotates the packaging bag 7 to the position, the front gripper 88 of the discharging machine 83 works, the movable gripper 100 and the fixed gripper 99 jointly act to clamp the packaging bag 7, meanwhile, the bag receiving structure 82 loosens the packaging bag 7, the packaging bag 7 clamped by the front gripper 88 reaches the sealing structure 84 under the action of the discharging machine 83, so that the sealing structure 84 clamps and seals the mouth of the packaging bag 7, then, the discharging machine 83 resets, the rear gripper 89 is positioned at the position of the sealing structure 84 and clamps the sealed packaging bag 7, meanwhile, after the front gripper 88 resets, the packaging bag 7 at the position of the bag receiving structure 82 continues to be clamped, the discharging machine 83 works, so that the packaging bag 7 in the front gripper 88 reaches the position of the sealing structure 84, the packaging bag 7 in the rear gripper 89 reaches the position of the code spraying structure 85, so that the packaging bag 7 is synchronously sealed at one time, And (4) spraying codes, and finally, enabling the coiled and packaged infusion tube to fall into other conveying belts and conveying the infusion tube to a designated position.

The infusion tube packaging mechanism provided by the embodiment of the invention is described in detail, the principle and the implementation mode of the invention are explained by applying specific examples, and the description of the embodiment is only used for helping to understand the technical scheme disclosed by the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation of the present invention.
