In the previous issue, we briefly introduced the working principle of the automatic unboxing machine. Due to the different materials and thicknesses of cardboard boxes used by various manufacturers, it is common to encounter issues such as inadequate or excessive feeding of cardboard boxes during use. In the past, the storage method used power transportation, coupled with poor carton forming methods, resulting in non-standard shapes after forming, which affects packaging quality.

      In response to the above issues, an automatic unpacking machine for corrugated cardboard boxes has been designed. Based on the principle of gravity sliding, a gravity sliding mechanism is used for automatic feeding, and pneumatic slide rail feeding and pneumatic folding side cover mechanism are designed.

      In addition, by adding screws and light bars to the upper box mechanism, vacuum suction box mechanism, rocker arm transport box mechanism, carton guide rail, compaction collision rod, and main frame, the size of the cartons opened by the unboxing machine can be flexibly adjusted. The automatic box opening machine for cardboard boxes is controlled by PLC, which automates the processes of suction, forming, folding side covers, pushing cardboard boxes, and sealing the bottom with cardboard tape.
