when the passing packing box 4 is extruded to the detection mechanism 14 (the packing box 4 takes the X-Z surface as the front and back surface and the Y-Z surface as the two side surfaces and passes through the detection mechanism 14), namely the limit plate 141 is also extruded to the contact 144 of the limit switch 143, the first push plate 15 pushes the packing box 4 to the second conveyor belt 17; when the passing packaging box 4 is not extruded to the detection mechanism 14 (the packaging box 4 takes the Y-Z plane as the front and back plane and the X-Z plane as the two side planes, and passes through the detection mechanism 14), that is, the limit plate 141 is not extruded to the contact 144 of the limit switch 143, the first push plate 15 does not act, and the packaging box 4 continues to be conveyed on the first conveyor belt 11.

Finally, the packaging boxes 4 on the second conveyor belt 17 are subjected to secondary alignment through the cooperation of the third width limiting plate 181 and the third guide plate 182; second limit for width board 161 cooperatees with second deflector 162 and carries out the secondary to packing box 4 on the first conveyer belt 11 and ajust, and above-mentioned design simple structure easily promotes, and the practicality is good.

The tail end of the second conveyor belt 17 is provided with a fan-shaped conveyor belt 19, bent plates 191 are arranged on two sides of the fan-shaped conveyor belt 19, and a packing box separating mechanism 2 is arranged at the tail end of the fan-shaped conveyor belt 19.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
