The single-column rotary arm wrapping machine is distinguished from the traditional gantry-type rotary arm wrapping machine. The traditional rotary arm wrapping machine is fixed by a frame composed of four columns, and uses a top slewing support structure to drive the suspension and rotary arm to rotate to achieve stretch wrapping. So what is the difference between a single column rotary arm wrapping machine and a traditional rotary arm wrapping machine, and what are the advantages and limitations of this new model?
First of all, we need to understand the structural composition of the single-column rotary arm wrapping machine. It is fixed on the ground through a single column. The top beam of the column is equipped with a slewing support bearing, and a single-sided rotary arm is installed on the bearing. From a structural point of view, it is not difficult to find that the rotary arm exerts a large vertical pull on the slewing support based on the lever principle. In addition, the cross beam exerts a large pull on the column. This not only requires the stability of the equipment when it is fixed to the ground, but also requires the supporting structure must not shift or dislocation during long-term use.
What are the advantages and limitations of this new model? Compared with the traditional rotary arm wrapping machine, it occupies a very small space, so we can also use it in some areas with limited space; compared with the turntable pallet wrapping machine, it still has the advantages of the rotary arm wrapping machine, which is the goods has no need to rotate with the turntable, which can ensure the stability of the goods during the stretch wrapping process. In terms of limitations, we first compare it with the traditional rotary arm wrapping machine. Due to the particularity of its structure, its rotation speed cannot be set too high, which leads to limitations in packaging efficiency. The efficiency is 25~30 pallets/hour. The traditional rotary arm wrap machine has an efficiency of 35~40 pallets/hour; compared with the turntable pallet wrapping machine, its mobility is limited. The turntable pallet wrapping machine can be adjusted with a forklift easily, while the rotary arm wrap machine is fixed on the ground with expansion bolts. After installation, it is not very convenient to move its position.
Analyze the applicable scenarios of the single-column rotary arm wrapping machine, we find it’s suitable for customers with site restrictions but less requirement for machine efficiency. A single-column rotary arm wrapping machine can be used when your palletized goods stability is not very good. However, when using this machine, you need to ensure the stability of its installation. You also need to pay attention to the rotation diameter of the rotary arm, and pay attention to the protection of the surrounding area to avoid the risk of intrusion by foreign objects.
