Stretch hooding machine pallet

Types of stretch hooding machines

Stretch hooding machine pallets are widely used in the packaging industry. They are usually divided into two types.

• Rotary arm stretch hooding machine pallet

The rotary arm stretch hooding machine operates by rotating around the load while the film is extended and applied over the pallet. This process provides the advantage of applying the film at various speeds and tension levels. Thus, it is suitable for a wide range of loads, from irregularly shaped items to lightweight products. The machine's operation is relatively fast, which is beneficial for high-volume applications. Nonetheless, this rotary arm machine requires a large amount of floor space. Therefore, it is important to consider the layout and logistics of the warehouse before purchasing the machine.

• Rotary ring stretch hooding machine pallet

The rotary ring stretch hooding machine operates in a similar way to the rotary arm machine. Unlike the rotary arm, the rotary ring moves the entire stretch hooding head around the pallet, making this model more compact and suitable for high-speed applications. The rotary ring machine can also be more adaptable than the rotary arm, as the ring can be moved up and down to adjust for different pallet heights. This makes the rotary ring a good option for a wide variety of products and pallet types. However, the rotary ring may not be as suitable for irregularly shaped loads as a stretch hooding machine with a robot arm. The rotary ring is also more expensive than some other types of stretch hooding machines, so it may not be the best choice for every application. Buyers should carefully consider the needs of their specific application before choosing a rotary ring stretch hooding machine.

When choosing a rotary ring stretch hooding machine, make sure to choose a reputable manufacturer with a good track record for reliability and customer service. Look for a manufacturer who can provide spare parts and service in case the machine needs repairs. It's also a good idea to read reviews from other customers to see if they have had a positive experience with the manufacturer and the machine itself.

Specifications and maintenance of stretch hooding machines

Typical specifications of stretch hooding machines are as follows:

• Machine operation: The machine is operated by a man-machine interface (PLC) for program control and easy operation. It also has an automatic alarm system that can quickly identify and solve problems.
• Palletizing capacity: The number of pallets the machine can stack in an hour. Capacity varies depending on factors such as machine type, load size, and programming.
• Package size: The size of the load the machine can stretch and hood. This is determined based on the machine's maximum film width and height capacity.
• Film type: The stretch hooding machine is compatible with different types of films, such as stretch films, LDPE films, LLDPE films, and other materials. The material is sourced from a reliable supplier to ensure the quality of the package.
• Machine dimensions and weight: The dimensions and weight of the machine, which are important for installation, placement, and transportation. Customers must consider the machine's dimensions and weight to ensure it fits their facility and can be easily transported.
• Conveyor system: The machine is equipped with a conveyor system that allows the pallets to be transported to the machine and away from the machine after the stretching and hooding process is completed. The conveyor system design and specifications depend on the machine configuration and the customer's facility layout.

Maintaining the stretch hooding machine properly can prolong the machine's life span, decrease malfunction frequency, and guarantee the machine's operating effect.

• Cleaning: Regular cleaning of the machine is essential. This includes dusting all components and vacuuming the inside of the machine to remove any film scraps or debris. This can help prevent the accumulation of dust and dirt inside the machine and on the surface. It will also help ensure the machine operates smoothly and efficiently.
• Lubrication: Regular lubrication of the machine is needed. This includes applying lubricant to the moving parts and components of the machine, such as bearings, chains, and rails. Regular lubrication can help reduce friction between machine parts, minimize wear and tear, and extend component lifespan. It also ensures smooth operation of the machine.
• Machine inspection: Regular machine inspections are important to detect any loose components, damaged parts, or abnormal conditions. This includes checking the fasteners, belts, chains, and electrical connections of the machine. If any problems are found during the inspection, they need to be addressed promptly to avoid further damage.
• Film quality: The quality of the film used is also important. Ensure the film's material and thickness are suitable for the load being wrapped by the machine. Before starting the machine, check the film roll for any damage or contamination. The film should be securely wrapped around the load with no wrinkles or gaps. Regular film replacement is necessary. This will ensure the film is continuously supplied to the machine and avoid interruptions in the hooding process.

How to Choose

When selecting a stretch hooding machine, it's crucial to first assess and understand specific packaging needs and requirements. Consider factors such as the type of products being packaged and their dimensions, the required level of protection, the desired stretch hooding film, packaging volume, automation requirements, and the production environment conditions. This will enable one to choose a machine that can efficiently meet their specific packaging demands.

Since stretch hooding machines come in various models and sizes, it's also important to consider the production volumes and velocities. Choose a machine whose capacity matches the production demand to ensure packaging operations run smoothly.

Assess the available budget to determine the stretch hooding machine that offers the best value within the set financial limits. While at it, remember to consider the long-term operating costs, such as maintenance and energy consumption, to ensure the machine remains cost-effective over time.

Opt for a machine that is easy to integrate into existing packaging lines. Compatibility with other equipment, such as conveyors and palletizers, is crucial for seamless integration and operational efficiency.

Ensure the stretch hooding machine selected is from a reputable manufacturer. Check the supplier's reputation, customer reviews, and track record to ensure they offer high-quality and reliable machines. A reputable manufacturer will provide excellent support and service whenever needed.

Q&A

Q1 What is the difference between stretch wrapping and stretch hooding?

A1: Stretch wrapping machines use film to wrap pallets in a spiral pattern. The film gets stretched to create tightness and tension. The film is wrapped around the pallets. The wrapping arm moves up and down as the turntable spins the pallet. The wrapping machine will cut the film once the pallet is fully wrapped.

Stretch hooding machines work similarly to stretch wrapping machines in that they use heat to seal the film. However, instead of wrapping the film around the pallet, the film is stretched like a hood and pulled over the entire pallet load. The film hood is shaped to fit the pallet and load and is then sealed at the bottom.

Q2: What are the different types of stretch wrappers?

A2: There are two main types of stretch wrapping machines: automatic and semi-automatic. Stretch wrapping machines can also be divided into two different categories: turntable and orbital machines. Turntable machines are the most common type of stretch wrapping machine. The film gets wrapped around a turntable that turns the pallet. On the other hand, orbital machines keep the film carriage in a fixed position, and it moves around the rotating load.

Q3: Is it worth investing in a stretch wrapping machine?

A3: Stretch wrapping machines have a quick return on investment. The machine helps in lowering labor costs, reducing film waste and improving load integrity. Companies that have high volume and consistent output can benefit the most from the machine. The machine will also help in streamlining the packaging process.
