A pallet wrapping machine, also known as a stretch wrapper, is a device that automates the process of wrapping palletized goods with stretch film. The machine rotates the pallet while dispensing the film, ensuring that the load is securely wrapped.
There are several types of pallet wrapping machines, including semi-automatic and fully automatic models. The basic principles of operation are similar for all types, though some of the steps may be automated in the more advanced models.
The following is a step-by-step guide to how a typical pallet-wrapping machine works:
The first step in using a pallet wrapping machine is to load the pallet with the goods to be wrapped. The pallet is typically loaded with the goods by a forklift or other material handling equipment. The goods are stacked on top of the pallet and arranged in a stable manner to prevent movement during transport.
Once the pallet is loaded, it is positioned on the turntable of the pallet wrapping machine. The turntable is part of the machine that rotates the pallet during the wrapping process. The pallet is positioned so that the turntable is centered under the stretch film dispenser.
The next step is to attach the stretch film to the pallet. The film is typically fed from a roll of pre-stretched film that is mounted on the machine. The end of the film is attached to the pallet by pressing it against the side of the load or by using a clamp or other attachment device.
With the film attached to the pallet, the wrapping process can begin. The turntable begins to rotate, and the stretch film dispenser begins to move up and down, wrapping the film around the pallet as it rotates. The speed of rotation and the speed of the film dispenser can be adjusted to suit the requirements of the load.
As the film is applied to the pallet, tension is applied to the film to ensure that it is stretched tight. This is done to prevent the load from shifting during transport and to provide stability to the load. The tension can be adjusted to suit the requirements of the load.
Once the wrapping process is complete, the film is cut to release the pallet from the machine. The film can be cut manually using a knife or other cutting device, or it can be cut automatically by the machine.
The final step is to unload the pallet from the machine. The pallet can be removed from the turntable by a forklift or other material-handling equipment and is ready for transport.
