Horizontal wrapping machines are indispensable solution conect to the production line for long shape packaging in various industries. The proper wrapping on the products surface ensuring that products are securely packaged for transport and storage.
The ability to adjust the packing tension is a critical function of these machines, as it directly influences the protection quality and integrity of the packaged items. Tight packing is crucial for preventing product movement and damage, particularly in industries such as electronics, where sensitive components can suffer from even minor jostling.
Conversely, loose packing can lead to shifting, damage, or even contamination of the product, a significant concern in the food and pharmaceutical sectors where product integrity is paramount.By providing precise tension control, horizontal wrapping machines help maintain product safety and quality throughout the distribution chain, reducing waste and increasing customer satisfaction.
These adjustments ensure that regardless of the product’s size, weight, or sensitivity, it remains secured and shielded from the potential hazards of transit.
Tension Control Methods available
a. Ring Height Level Adjustment
One of the primary techniques for managing packing tension in horizontal wrapping machines is through the adjustment of the ring height, which is now enhanced by a motor-driven mechanism coupled with a sliding main board. This sophisticated setup includes height level monitoring via sensors and encoders, allowing for precise control and accommodation of different package sizes and shapes.
For example, if the ring is positioned too high for a smaller package, it can result in loose packing and subsequent instability. On the other hand, lowering the ring for larger items ensures a snug fit, significantly reducing the risk of displacement or damage during transportation and handling.
This method is highly adaptable, capable of handling packages with heights ranging from 100 mm to 1200 mm. Such precision ensures that products, irrespective of their dimensions, are securely wrapped and protected, enhancing the machine’s versatility and efficiency in industrial packaging operations.
b. Packing Material Carriage with Tension Adjusting Device
Another critical component in horizontal wrapping machines is the packing material carriage, which features a tension adjusting device. This device enables operators to precisely set the desired tension level for the film or wrapping material, adjustable from 2 to 30 kg of force to match the product’s fragility and weight.
The mechanism typically operates through an internally threaded nut that compresses a spring, coupled with a plain bearing to enhance the dispensing of the film during the wrapping process. Additionally, the inclusion of a brake pad on the rotating shaft further refines the control over the film tension, preventing slippage and ensuring a consistent application.
By fine-tuning the tension, the machine guarantees that each product is wrapped securely, maintaining tightness to keep the items stable and protected during transit, yet not so tight as to risk damage. This balance is crucial for preserving the integrity and quality of a wide range of products, making the machine an essential tool in various industrial packaging lines.
c. Mechanical Drawing Back Device
To effectively address issues of loose film in packaging, many horizontal wrapping machines are equipped with a mechanical drawing back device. This innovative mechanism is designed to automatically retract excess film, thereby tightening the packaging after the initial application.
This feature becomes particularly vital for products that may settle or shift slightly once wrapped, ensuring that the wrap remains consistently tight even if the initial conditions of the product change.
The mechanical drawing back device typically operates through an accumulator-based mechanical structure, which enhances the stretch of the film during the wrapping process. By expanding and contracting the travel path of the film, this structure allows for consistent tension maintenance throughout the wrapping cycle.
This capability is especially important when dealing with volatile or irregularly shaped items, where even minor variations in tension can lead to wrapping failures or product damage.
The accumulator’s role in extending the film’s travel path not only compensates for any slack but also adapts dynamically to changes in product dimensions or machine speed. This adaptability ensures that each product, regardless of shape or size, is secured with optimal tightness, maintaining high standards of pack integrity and safeguarding the items against potential transit or storage hazards.
d. Automatic Motor Driving Film Carriage for Film Pre-stretch and Drawing Back
Modern horizontal wrapping machines are increasingly equipped with an automatic motor-driven film carriage, significantly enhancing the efficiency and effectiveness of the wrapping process. This advanced carriage not only pre-stretches the film, potentially extending it by 100% to 300%, but also has the capability to retract the film as needed.
Such dual functionality not only reduces film usage by up to 50% compared to non-stretched applications but also ensures optimal tension throughout the wrapping cycle, thereby enhancing the strength and security of the wrap.
The functionality of these systems necessitates the electrification of the rotating ring, which powers the motor even while in motion, enabling it to perform both forward and reverse rotations. This capability is crucial for eliminating excess film caused by eccentricity during the wrapping process. Additionally, upgrading from conventional motors to servo motors in these machines can provide more precise control over the film tension and carriage movements.
The use of servo motors allows for finer adjustments and improved consistency in the wrap, crucial for maintaining high-quality packaging standards, particularly when dealing with delicate or irregularly shaped products.
