Video Overview: Measuring For A Conveyor Dryer Belt ...

Description

For all screen printers, there will come a time when you need to replace your conveyor dryer belt. Just like you want quality screen printing equipment from a reputable source, replacement tunnel belts should be purchased correctly. To do so, it is critically important that the measurement is right. Here are the three (3) basic ways for measuring the overall length of your dryer belt when ordering a replacement conveyor belt.

If you are looking for more details, kindly visit SINODA.

The first, and by far easiest way is the contact your screen printing machine manufacturer. Ask them "what is the length of my dryer belt?" Remember to mention if you purchased an additional in-feed or out-feed, or any other modifications made.

If you are unable to obtain the information for the screen printing equipment manufacturer, then the next option is to take off the belt and lay it flat on a surface, such as you screen print shop floor. Now you can measure it yourself.

If you do not want to remove your screen printing dryer belt, use the &#;String Method.&#; Following this procedure to measure your screen printing conveyor tunnel dryer belt is relatively easy. Follow the simple step-by-step procedure below.

  1. Take a ball of string (twine) and tie it around one of the laced openings.
  2. Run the dryer belt until the initial knot appears. Make sure the twine/string is pulled taught, and then cut the twine/string so you have a complete loop.
  3. Measure the length of the string. This is the length of your dryer belt.

If your t-shirt dryer belt only has a small hole in it, consider purchasing a Conveyor Repair Kit instead.

How are belts measured?

In the case of standard configuration (belt extended between two pulleys with the same diameter), the theoretical belt length is equal to the pulley circumference + (2x the centre distance).
For any other configurations, kindly send us a dimensional drawing of the installation.
In all cases, the tension system must be returned to its minimum position.

Our technicians are available to help you define your needs.

What is the HACCP process?

The HACCP (Hazard Analysis Critical Control Point) process is a method intended to reduce the maximum number of sanitary risks in agri-food industries. This method is based on 7 main principles aiming to control risks during the process and to analyse the hazards during verification of the effectiveness of the implemented system. The Mafdel range of belts and conveyor belts helps provide an optimum level of hygiene to satisfy the requirements of this process.

How do Mafdel products help achieve an optimum level of hygiene in the agri-food industries?

One of our priorities is to provide quality products that contribute to compliance with hygiene standards. Our belts and conveyor belts in the agri-food range comply with the most stringent standards and offer characteristics that help attain an optimum level of hygiene:

  • Our mono-material products do not have textile threads, which eliminates the risk of fraying
  • Waterproof and rot-resistant products
  • Easy to clean
  • Resistance to chemical aggression: solvents, oils, fats, cleaning products, etc.
Using Mafdel belts and conveyor belts also helps satisfy HACCP process requirements. What is the difference then between flat belts and conveyor belts?

Our definition: - Flat belts have a width of less than 100 mm. - Conveyor belts have a width greater than or equal to 100 mm.

In what case or cases should High Density Polyethylene (HDPE) runners be used?

HDPE runners offer excellent guiding for round or trapezoidal belts. They also help improve the friction coefficient and therefore increase the transported load. > See more details in the Belt runners section

What is cogging used for on v-belts?

Cogging allows increased belt flexibility and therefore reduces the minimum pulley diameter. Cogging cannot be used for driving using a cogged pulley.

How do you weld a reinforced belt?

Our reinforced belts can be welded together in the same way as our non-reinforced belts, using just an iron and clamp. The aramid reinforcement on our belts is resistant to very high temperatures, it does not need the reinforcement to be removed at the joint before welding. Both types of welds (end-to-end and overlap) can be used.

Why use reinforced belts?

Aramid reinforcement stops elongation on our round and v-belts. This allows for use of long-length belts, while at the same time minimising the need for long travel tensioning devices. The maximum allowable load is also higher, especially with our overlap weld.

How are belts measured?

For any other configurations, kindly send us a dimensional drawing of the installation. In all cases, the tension system must be returned to its minimum position. Our technicians are available to help you define your needs.

How are belts tensioned?

Exerted tension depends on the type of belt used (from 0.5% to 8% for Mafdel belts &#; see the catalogue for recommendations). There are two ways to apply tension to a belt:

  • The conveyor is equipped with a suitable tensioning system: In this case, the tensioner must be set to the minimum, install the belt and adjust the tensioner to apply the belt tension.
  • The conveyor is not equipped with a tensioning system, or it is insufficient: In this case, you must use pre-tensioning tools comprising a winch and two tightening jaws, which will enable you to pull the belt ends together and then apply the welding process.
If the belt is reinforced, you must take care not to apply excessive force, which could destroy the reinforcement. How to weld a conveyor belt?

All belts can be endless welded or delivered open for on-site welding. Conveyor belts can be welded in two ways:

The company is the world’s best Grip Top Modular Belt supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

  • Thermowelding: We offer our end-to-end welding kits. Option for hot air welding (adding material).
  • Fasteners: Belts can also be jointed using polyurethane or stainless still clips (recommended for pulley diameters greater than 120 mm). This type of jointing is highly recommended for frequent assembly/disassembly or for repair.
