[0049] As Figure 2As shown in the figure, it is a schematic structural diagram of a medical garbage bag. After the bag body 21 is formed, a reinforcement layer 22 is fixed on the surface of the bag body 21 by hot pressing or ultrasonic welding, and a target area 23 for spraying a coding identification code is arranged on the surface of the reinforcement layer 22.

[0050] In an alternative embodiment of the present invention, the controller 11 includes:

[0053] In this embodiment, a CCD camera 14 is arranged on the conveying device 16. The CCD camera 14 is electrically connected to the controller 11. The CCD camera 14 is used for acquiring image information of the target area 23 on the bag body 21 and transmitting the image information to the first acquisition module; the processing module determines, according to the image information, the first position information of the target area 23 of the medical garbage bag on the conveying device 16; and obtains the position offset information of the target area 23 of the medical garbage bag according to the first position information and the standard position information. Wherein, in the initial state, the nozzle of the coding device 12 corresponds to the width center line of the conveying device 16, and the standard position information is the position information of the target area 23 in the ideal state, that is, the position information of the target area 23 when the center of the target area 23 falls on the width center line of the conveying device 16.
