Is the pallet inconvenient to rotate because the goods are too heavy? Rocker wrapping machine makes packaging safer and more efficient

In the context of the continuous evolution of logistics packaging towards efficiency, safety, and intelligence, many companies face a common problem in the process of wrapping pallet goods: when the goods are large in size, heavy in weight, or the stacking height is unstable, the traditional turntable wrapping method is prone to offset and displacement due to the rotation of the pallet, and in severe cases, it may even cause the risk of rollover. Especially in the bulk shipment scenarios of heavy industry, paper products, building materials, electronic equipment and other industries, it is required to wrap tightly and keep the goods still to reduce disturbance. It is under such demand that the rocker wrapping machine has become the first choice of many users as an automatic packaging equipment. Through the method of "goods do not move, film arm moves", while ensuring the quality of packaging, it also improves the safety and efficiency of on-site operations.

The core design of the rocker wrapping machine is that it uses a rotating arm to wrap the goods instead of rotating the pallet body. This structure determines that the equipment has better stability when facing super-heavy goods, high-center-of-gravity products and special-shaped pallets. When the equipment is running, the film frame is installed on one side of the rotating arm, and the film is wrapped around the goods in circles at the set speed. At the same time, the film frame that can be adjusted up and down cooperates with the photoelectric sensing system to automatically sense the height of the goods, thereby performing the full-process intelligent wrapping operation. Compared with the traditional turntable wrapping machine, the rocker arm structure greatly reduces the potential risks of pallet slippage, equipment overload, motor loss, etc., and is particularly stable in daily high-intensity work.

A large chemical company in Shandong encountered the problem of poor adaptation of traditional wrapping machines during the transformation and upgrading of packaging equipment in 2023. Since the company's shipments are mainly ton barrels and IBC container barrels, each pallet weighs more than 800 kilograms. The manual wrapping method is labor-intensive and has many unsafe factors. The turntable wrapping is easy to shake or even shift during the rotation due to the high center of gravity of the goods, affecting the wrapping effect and safety factor. After several rounds of comparison, the project team finally selected a double-station rocker wrapping machine as the main packaging station. After the transformation, the equipment can automatically identify goods of different heights, support multi-stage film setting, and has good top reinforcement and bottom fixed wrapping effects. At the same time, combined with the film pre-stretching mechanism, it can save about 22% of consumables, and the packaging efficiency is increased to more than 40 pallets per hour, achieving a truly high-quality delivery guarantee.

In terms of control configuration, the current mainstream rocker wrapping machines in the market are mostly equipped with PLC program control and touch-screen operation interface, supporting one-key setting and automatic memory of multiple packaging parameters, and no need to reprogram when switching cargo types. The film rack system mostly adopts a power pre-stretching structure, with an adjustable speed film feeding motor and a tension feedback system to achieve a tighter and more stable film wrapping effect. At the same time, the equipment supports additional top pressure devices, heat cutting systems, corner edge strengtheners and other expansion functions, and can be modularly customized according to cargo attributes and shipping needs, and flexibly adapt to various packaging forms from standard pallets to irregular stacking.

It is worth noting that the rocker wrapping machine is also more flexible in space utilization. Since there is no need to reserve space for the turntable to rotate, the equipment body is compact in size and occupies a smaller area, which is especially suitable for on-site environments with limited factory ground and irregular packaging stations. Some models can also be connected with the online conveying system and the palletizing system to achieve continuous operation and seamless linkage, effectively avoid manual handling, reduce operating costs, and provide a whole-line automated packaging solution for high-frequency shipping companies.

In the actual procurement process, many users pay attention not only to the price of the equipment, but also to the stability, efficiency performance and maintenance convenience of the equipment in long-term operation. The rocker arm wrapping machine is widely recognized in the industry for its concentrated key components, short transmission path and low failure rate. Most of the vulnerable parts such as film racks, swing arms, and motors adopt modular design, which is easy to maintain and quick to replace consumables without affecting the continuous operation rhythm. For medium and large enterprises with a daily production capacity of more than 100 pallets, this equipment can almost achieve all-weather operation guarantee, which is an important tool for achieving packaging standardization, rhythm stabilization and cost control.

In general, the rocker wrapping machine has completely broken the limitations of traditional packaging methods on the weight and shape of goods by changing the wrapping logic from "moving goods" to "moving film", providing a more stable, safer and more efficient packaging solution for manufacturing companies in the upgrading and transformation period. In modern production sites that emphasize efficiency, quality and safety, a suitable set of wrapping equipment is not only a process tool, but also a part of the company's delivery capabilities.
