[0028] It should be noted that the size of the paper boxes to be packaged is input into the storage of the controller in advance, and then the signal variables generated by the corresponding infrared laser rangefinder 25 are associated with different sizes respectively. At the same time, the signal variables of the infrared laser rangefinder 25 are associated with the action strokes of the electric push rod 36 and the hydraulic rod respectively, so that different paper boxes can obtain corresponding positioning effects and packaging effects when packaging.

[0030] As a preferred embodiment, the guide frame 22 and the guide rod 261 are provided to enable the horizontal plate 24 and the inclined plate 26 to perform stable telescopic movements.

[0031] As a preferred implementation, by providing a reflective plate inside the support plate 21 , the ranging accuracy of the infrared laser rangefinder 25 can be enhanced.

[0034] Among them, the ion fan 331 is a static electricity removal device in the prior art, and its function is to blow out ion wind with positive and negative ions to neutralize the charge on the surface of the object.

[0035] As a preferred embodiment, by setting up the mounting flange 334 and the guide tube 335, it is convenient to change the air outlet direction of the ion blower 331 in the prior art, and then the dust removal and static electricity removal effect is achieved by blowing the ion wind to the upper side of the paper box through the air distribution tube 342 and the air outlet nozzle 344.

[0036] When in use, the carton containing the product is conveyed to the first positioning mechanism through the roller conveyor line, enters between the horizontal plates through the inclined plate, and then the displacement of the carton squeezing the horizontal plate outward is measured by the infrared laser rangefinder.
