de sacos de bobina ENF-15

Description

The ENF-15 bag forming and filling machine has been designed to form, fill and close medium and large content bags from a flat polyethylene reel.

It allows for the bagging of a large number of products, both granulated and powdery.

With a robust and reliable design, the ENF-15 bag forming and filling machine from reel is characterised by its almost hydraulic operation, which allows it to be used in difficult working conditions.

The hydraulic drive also allows for higher pressures, ensuring more resistant seals.

Thanks to its simplicity and flexibility, it adopts effective systems that allow for very prolonged use with minimal maintenance.

OPERATING PRINCIPLE

The film from the reel, located at the rear of the packaging machine, is unwound from the reel and brought to the beginning of the forming tube thanks to a system of tensioning rollers.

The lateral centring of the reel is carried out by means of handwheels.
The film tension can be adjusted to compensate for poor winding of the polyethylene or uneven tension at the ends of the reel.

The film is curved around the forming tube to form a polyethylene tube. The longitudinal sealing jaw is hydraulically operated.
The film traction is carried out by two belts mounted on toothed pulleys.

The constant pressure of these belts against the film and forming tube is carried out by means of a mechanism that ensures equivalent pressure on both sides.
This system prevents film breakage and rapid wear of the toothed belts.
The print centring is carried out by detecting the “mark” with an adjustable position photocell.

The machine is synchronised with the dosing system, which can be:

  • Volumetric dosing unit.
  • Auger dosing unit.
  • Electronic weigher.

The electronic control automatically determines the moment of product discharge.

Simultaneously, the belts pull the film until the bottom of the bag descends to the tray-grill that will support the bag.
The two hydraulically operated horizontal sealing devices respect the product fall time.

The sealing system is composed of 2 sealing bars in the middle of which is a blade of the same length. In a single operation, the device will seal the top of the filled bag and the bottom of the new bag, separating them by a cold cut.
The Tecnival can be equipped with a side gusset forming device.

PELLET BAG SEALING MACHINE WITH VERTICAL FILM, PALLETIZER, AND WRAPPER– ENESVAL

Enesval, the Spanish manufacturer of automatic bag placers, offers the best solutions through its advanced techniques for packaging and palletising solid products. In this video, we can see the automation of a pellet bag production line consisting of an automatic pellet bag packer with vertical film, a drag palletiser and an automatic ENF-500 turntable wrapping machine. This bagging machine is capable of automatically placing the bag, filling it with the product weighed by a scale, and closing it using a sewing system. All of this with great precision, speed and safety. Enesval’s high-production automatic bag placers can work with bags of different materials, sizes and weights, from 5Kg to 25Kg. Additionally, it has an empty bag storage that can be refilled without the need to stop production. The automatic bagging machine is complemented by a drag palletiser and a wrapper that allow stacking and protecting the pellet bags for transport and storage. We eliminate bottlenecks in production, as well as increase bag production, optimising the industrial process and reducing operating costs. Enesval has more than 30 years of experience in the design, manufacture and installation of equipment and systems for packaging and palletising solid products. The company offers tailor-made solutions for each client, adapting to their needs and requirements. If you want to see the pellet bag packer with vertical film, palletiser and wrapper in action, you can watch the following video, which shows its operation and features. And if you have any questions or doubts, don’t hesitate to contact Enesval’s engineers, who will be happy to assist you. Enesval is your ally to optimise your industrial process with effective and cost-efficient solutions.

Tubular Plastic Reel Packer ENF-15 – Enesval

The ENF-15 Bag Forming and Filling Machine from Reel is absolutely versatile, as it can work with bags from 5 to 50 kgs. It has a bag picking and opening system that allows it to work with paper bags, plasticised raffia, normal raffia and polyethylene. Sewn or welded. Due to its technical development, it can handle both gusseted and stretched bags without having to make any mechanical adjustments. Some key points about reel bagging machines like the ENF-15 bagger: • Reel baggers like the ENF-15 are designed to form, fill and seal plastic bags or sacks from a continuous polyethylene film reel. • They are versatile machines that allow packaging a wide variety of granulated or powdered products, from foods such as flours and sugars, to chemical products, fertilisers, etc. • The plastic reel is unwound, the bag is formed by thermal welding, the product is filled and then the bag is also sealed by heat. The entire process is automatic. • They allow high-performance and high-speed packaging, bagging large quantities of product in less time compared to manual bagging. • They are robust and reliable machines, with the possibility of adjusting different sizes and shapes of bags as needed. • They require simple operation and maintenance. They usually incorporate automated control systems. • Versatility: they can be programmed to make bags of different sizes, shapes (square, rectangular), film materials, with or without vacuum valve, etc. • Easy format change: changing from one bag format to another is done simply and quickly using the touch control panel. • Precise dosing: they incorporate volumetric or gravimetric filling systems that ensure the correct weight of the product in each bag. • High sealing quality: the sealing resistances allow for a hermetic closure of the bags, preventing product spillage. • Low maintenance: they have few moving components, which reduces maintenance. Cleaning is simple thanks to the sanitary design. • Self-diagnosis: ability to detect and report faults for quick repair. • Compliance with regulations: they comply with hygiene and food safety regulations. Suitable for ATEX environments if required. • Profitability: process automation reduces labour costs and increases productivity. In conclusion, this type of packaging machine represents an efficient and cost-effective solution to optimise large-scale bagging processes in different industries.
