Eyelink belts

Description

At Twentebelt, we understand that your production process requires optimal support to function efficiently and reliably. As a specialist in eyelink belts, we are at your service to take your production to the next level. Our eyelink conveyor belts are the perfect solution for heavy loads, and unstable or fragile products that require even and stable product support.

An eyelink conveyor belt is composed of calibrated eyelinks, plate links and cross rods. Eyelinks are wire elements produced with great precision, whose far ends are eye-shaped, which explains the name. By assembling the eyes on to cross rods a hinge construction is created. Plate links transfer the load to underlying support sections, and are installed in rows at a regular distance.

Whether your process requires eyelink belts with pressed eye-links for the smallest possible opening, or eyelink belts with springs for good shock resistance and lateral forces, we have the solution that perfectly matches your specific needs.

Advantages of eyelink conveyor belts

Single level surface
The single level belt surface excludes a possible ‘tunnel effect’, so products and/or parts will not get entrapped between several layers of the belt.

Excellent air and fluid drainage
The drainage for air and fluids is excellent. This makes sure that the processing circumstances of different zones of the process hardly influence each other.

Solid belts with a long life span
Eyelink belts have a considerably long life span, even when they are used under the heavy conditions of a 24/7 production line.

Reliable and efficiënt performance
An eyelink belt that is optimized for your process performs better and has less wear and tear.

Food safety
Produced according to the latest food safety requirements such as FDA, GMP en 1935/2004/EC.

Features

The benefits of eyelink conveyor belts
An even and stable belt surface, combined with the robustness and dimensional stability of metal, that’s what our eyelink belts have to offer. This makes them exceptionally suitable for various industrial processes. Thanks to the drive with toothed sprockets and/or rollers, we guarantee a perfectly straight belt run, which contributes to consistent and efficient production.

High-quality materials and construction
Twentebelt’s eyelink belts are generally made of stainless steel. They consist of a series of eye-links or eye-link modules and are connected by cross rods. This design ensures a durable and reliable conveyor belt, which is easy to clean thanks to the open design and the primarily round shapes of the different elements.

Efficient and hygienic solutions
Our eyelink conveyor belts are designed to make your production processes more efficient and economical. The even belt surface provides stable product support, which results in a consistent end product with minimal product marking. In addition, the single layer surface ensures that products and components do not get stuck between multiple layers of the belt and provides optimal air and liquid permeability.

Reliable and easy to maintain
Twentebelt’s eyelink belts are exceptionally solid and have a long lifespan, even in harsh 24/7 production environments. Thanks to their modular structure, these conveyor belts can be repaired (if necessary), which contributes to minimal downtime and maximum productivity.

Belt types

Full eye-links (DO type conveyor belts)
The basic principle of all eyelink belts versions. On a full eyelink belt the eyelinks lie against each other, and the opening is equal to the wire diameter. This type can best be used for products likely to fall, or for applications that require small openings.

Pressed eye-links (DP type conveyor belts)
Some applications require the smallest opening possible. By flattening the eyes of the eyelinks the opening between the links becomes smaller. This type is very appropriate for small and fine-structured products.

Eye-links with springs (DV type conveyor belts)
The placement of springs between the eyelinks ensures that they are positioned at regular intervals. The result is a relatively light belt with specific qualities, such as a good shock resistance and resistance to lateral forces. This is important in situations when the conveyor belt is loaded manually and/or laterally.

Welded eye-links (DL type conveyor belts)
The eyelinks are welded on to an location wire, so that a module is created. Very narrow and very wide openings can be created, depending on the processing of the products concerned.

Pressed and welded eye-links (DPL type conveyor belts)
Some applications require a stable belt in combination with a small opening/drain. The accuracy of our welding process allows us to produce modules with very small intervals between the eyelinks. The modular structure makes the assembly of very broad belts possible.

Eye-links with brushings or washers (DB type conveyor belts)
Bushings or washers are meant to create an opening between the eyelinks. When bushings or washers are added the belts become heavier and more rigid.

Side finishing / belt options

Side finishes

Welded edge (LK)
At both sides the belt is fitted with plate links, and the far ends of the cross rods are fitted with washers and subsequently welded. This results in a thorough finishing of the belt in combination with the desired bearing surface.

Side chains (KH)
Eyelink conveyor belts are usually fitted with chains, if the belt is to perform a negative bend. For this purpose only hollow pin roller chains are used with pitch measurement equal to those of the belt. The selection of the chains depends on the operating conditions.

Belt options

Edge plates
All Twentebelt eyelink conveyor belts can be provided with edge plates that make it possible to control the layer thickness of the product to be transported. The height and the shape of the edge plates can be adapted to the sort of product and to the process.

Guide plates (GP)
Guide plates serve as a protection for the welding heads. The plates actually function as a “buffer” between the welding heads and the guidance or other constructions the sides of the belt can get in touch with.

Plastic blocks (KB)
Plastic blocks are a patented item of Twentebelt. This product has several functions, which among other things improve the modular qualities of the eyelink belt (no welds), and generally also the hygiene.

Flights
For ascending and/or descending eyelink belts, flights can be fitted. The shape, measurements and structure (open / closed) of the flights will again be adapted to the sort of product and to the process.

Drive sprockets

Sprockets
Generally, eyelink conveyor belts are driven directly on the eyelinks by means of specially developed drive sprockets. For DO belts these sprockets are provided with block teeth. In the case of DL belts the sprockets are constructed such that they exactly match the profiles at the underside of the belt. In case of belts with a large cross pitch (centre-to-centre distance of eyelinks) one could consider to place sprockets that are directly driven on the cross rod instead of on the eyelinks. Generally the sprockets are placed at both sides and under each row of plate links. The width, the number of teeth and the material of the sprockets are determined on the basis of the conditions of use.

When a construction of drive sprockets is applied in a freezer, sprockets with special toothing are used. In order to prevent the accumulation of ice, the so-called ‘ice-crusher’ sprockets are used. The special toothing limits the accumulation of ice to the minimum.

Sprockets are available in steel, AISI 304 (WS 1.4301), AISI 316 (WS 1.4401), PA6G and POM, or in other materials on request or on advice. An example of a stainless steel sprocket is featured below.

Chain sprockets
Eyelink belts can also be produced with chains, whereby the chain fulfils a driving function. Especially when the belt has to perform a negative bend, as is the case with many applications for freezing or blanching, and for ascending belts. In those applications the side-sprockets are replaced by chain sprockets belonging to the chain applied.

In this case, too, the rule applies that for bigger constructions chain sprockets will be placed in combination with a roller.

In all applications with chains a negative bend of the belt can easily be achieved by means of chain sprockets or wear strips of the hollow pin roller chain. Twentebelt prefers the use of sprockets with at least 12 teeth. This is based on the fact that with this number of teeth the so-called polygon effect will exert hardly any influence on the belt run. If the length and the load of the belt are moderate drive sprockets with a minimum of 8 teeth might be used. The ultimate determination of the necessary number of teeth depends on factors like width, length, load and running speed of the belt.

Cage rollers
Broad and heavily loaded eyelink conveyor belts are preferably driven by rollers right across the width of the belt, cage rollers in most of the cases. The straps of the roller regularly drive all the eyelinks of the pitch, which is conducive to a longer life span of the belt and also leads to a regular wear pattern.

Disc rollers
If there is a risk of accumulation of filth or ice, disc rollers should preferably be used. On a multiple of the cross pitch these rollers are provided with discs. These discs can be produced in different ways, so that different properties can be created:

– Drive on the cross rod
– Drive on the cross rod with a ‘lifting function’, where the teeth protrude through the belt and lift the product for discharge.

Tube rollers
In the grooves of tube rollers with replaceable strips, plastic or soft-metal strips are placed. In case of tube rollers with replaceable teeth, the teeth are not welded but screwed in. This construction has three advantages:

– The tube construction limits deflection.
– The drive components are replaceable.
– The roller is reversible, which makes a second life cycle of the strips and the teeth possible, before they must be replaced.
In general, tube rollers drive long, broad and heavily loaded belts.

Idler
As for the return shaft there is a choice between toothed or smooth wheels or rollers. In principle, toothing only has a function in case of accumulation of ice or filth. Toothing on the return shaft consequently has no drive function. Generally, in small installations one prefers to provide the return shaft with toothed wheels. When, however, a cage roller was chosen to drive the belt, a smooth roller will be chosen for the return shaft. An exception to this is a drive with cage rollers and chain wheels, whereby the same construction is used as a return roller.

If provided with one tooth per pitch the rollers are one-directional and thus only to be used for drive or for return. Rollers with double strips can be used for both drive and return, if the installation is designed for this purpose.

Built for durability and long service life

A defining strength of the eyelink belt is its durability. These solid belts are designed to withstand continuous mechanical stress and thermal variations. This results in stable operation, extended belt lifespan and lower replacement frequency. The construction also supports accurate tracking with minimal stretch, even during long and demanding production cycles.

Versatile applications across industries

Eyelink belts are used widely in food and industrial processing. They are frequently installed in baking lines, cooling tunnels, drying installations, freezing systems, pasteurising units and washing or rinsing processes. Each belt is manufactured to customer-specific dimensions, pitch requirements and material selections to achieve optimal performance in any application.

Our other belts

Wire mesh belts

Wire mesh conveyor belts are exceptionally efficient, both in terms of applications and specifications. Due to their open structure, they are very suitable for light products and applications where the product needs to have the smallest contact area with the conveyor belt as possible.

Balanced weave belts

Balanced weave conveyor belts offer an extensive number of designs and applications. From ultra-powerful for heavy loads across large widths or very hot products, to very densely woven for small products or bulk materials. No application is too complex for spiral and braided conveyor belts to offer a solution.

TwenteFlex spiral belts

TwenteFlex is our spiral conveyor belt with a unique design without welded connections. The smart design ensures less downtime and eliminates several major causes of conveyor belt problems. TwenteFlex is used worldwide in spiral towers and can be powered by low tension as well as direct drive.

TwenteSideFlex

TwenteSideFlex is based on the unique design of our TwenteFlex and is designed for use in spiral or oval systems, without a central drum driving the belt. This is our external direct drive solution that may suit your application, system, or workspace better than low tension or inside direct drive.
