Automatic winding and dog-ear folding machine for packaging boxes

The invention relates to an automatic adhesive tape winding and dog-ear folding device which adopts a PLC module control system and perfectly combines pneumatics, electrics and mechanics. Automatic feeding and discharging of packaging boxes are realized through a feeding conveying roller and a discharging conveying roller. A jacking positioning mechanism is matched with a pressing mechanism to realize positioning and clamping of the packaging boxes. An adhesive tape rolling mechanism attaches adhesive tape to appointed positions of the packaging boxes. A winding rotary mechanism drives a workpiece to rotate to achieve winding of the adhesive tape, and then a telescopic air cylinder drives a cutter to cut off the adhesive tape. A vacuum sucker mechanism is matched with a pinhole air pipe to achieve dog-ear folding of the tail end of the adhesive tape. An air brush evenly flattens the adhesive tape obtained after dog-ear folding on the surfaces of the packaging boxes. Automatic conveying, positioning and windin
