High Pallets Difficult to Rotate? Application Analysis of Rotary Arm Automatic Stretch Wrapping Machines in Pallet Packaging

In pallet packaging operations, some loads are not suitable for turntable rotation due to excessive height, unstable centers of gravity, or special bottom structures. Forcing such pallets to rotate may cause load shifting or even collapse, increasing packaging risks. To address this practical issue, rotary arm automatic stretch wrapping machines have gradually been adopted in pallet packaging environments, using a “stationary load, rotating arm” method to complete film wrapping.
Packaging Application Scenarios of the Rotary Arm Structure
The core structure of a rotary arm automatic stretch wrapping machine is the rotating arm. During operation, the pallet remains stationary while the arm drives the film carriage to rotate around the load. This configuration is particularly suitable for tall pallets, loads with moderate stability, or pallets that are not suitable for turntable bearing. By eliminating pallet rotation, the risk of load displacement during wrapping is effectively reduced, improving operational safety.
Actual Operating Process of Automatic Wrapping
In practical applications, the rotary arm automatic stretch wrapping machine completes film loading, continuous wrapping, and finishing operations through preset programs. The machine automatically adjusts the vertical travel of the film carriage according to pallet height, ensuring even film coverage at different levels. During wrapping, the rotation speed of the arm and the film tension remain stable, contributing to consistent wrapping quality.
Influence of the Pre-stretch Film Carriage on Packaging Results
Rotary arm automatic stretch wrapping machines are typically equipped with a pre-stretch film carriage. By stretching the film to a defined ratio in advance, the film maintains good adhesion during wrapping. This structure helps reduce film consumption while improving the overall tightness of the pallet load. For pallets requiring long-distance transportation or frequent handling, this wrapping method provides enhanced load stability.
Parameter Settings for Different Pallet Specifications
Pallet size, load height, and weight vary across applications. Rotary arm automatic stretch wrapping machines allow adjustment of wrapping cycles, arm rotation speed, and film carriage lifting height through a PLC control system. Operators can select appropriate programs based on actual load conditions, ensuring consistent packaging results across different pallet specifications.
Typical Industry Applications
In industries such as chemicals, building materials, beverages, new energy materials, and warehousing logistics, rotary arm automatic stretch wrapping machines are commonly used for outbound packaging of tall or heavy pallets. After wrapping, pallet loads exhibit improved integrity, facilitating forklift handling and stacking while reducing external impacts during transportation.
Overall, rotary arm automatic stretch wrapping machines provide a practical packaging solution for tall pallets and loads that are unsuitable for rotation. By completing automatic wrapping through arm rotation, these machines enhance packaging stability and consistency. Selecting appropriate equipment based on load characteristics and outbound requirements helps ensure orderly and reliable pallet packaging operations.
