Process flow: Using the differential speed ratio of the wear-resistant rubber roller, the PE stretch film is fully stretched and evenly wrapped around the rotating pallet goods. The corresponding parameters such as the packaging process and packaging volume can be freely set. After the sensors in each part collect and return data, they are summarized into the central processor (ie PLC). After the PLC processes the received data, it coordinates and controls the equipment to make corresponding responses. Actions. Description of the whole packaging process: Set the number of packaging layers and the number of reinforcement turns (unless the firmness of the packaging needs to be changed, generally the parameters can be set once), fix the stretch film to the pallet to be packaged, and press the “Run” button , after the winding machine completes operation according to the established parameters, the film is manually cut off and the packaging is completed.
