This 25KG plastic pellet unpacking machine is a fully automated bag opening and discharging solution designed specifically for chemical, plastic, and building material industries. As shown in our commissioning site photo, the column-type cantilever robotic arm structure offers a compact footprint, wide 360° rotation, and flexible adaptability to various feeding points in your factory.
Core Features of Column Unpacking Machine
-
Rotary Cantilever Robotic Arm: Supported by a sturdy column base, the arm handles 25kg standard bags with smooth operation, transporting them gently yet precisely to the breaking area.
-
Bag-breaking Hopper (Bag Slitter): Features an enclosed design with an integrated cutting mechanism (sharp blades/knives) that swiftly opens the bags while ensuring 100% material discharge, achieving perfect “bag-material separation”.
-
Dust-free Design: Comes with a standard dust collection port that connects to your factory’s centralized dust extraction system, completely eliminating dust emissions during the unpacking process and protecting operators’ health.
