Problem Analysis of ribbed belt
Problem Analysis of ribbed belt
Malfunctions during mechanical use are very tricky.When troubleshooting belt faults, in addition to replacing new products, finding the cause of the fault and mastering the correct use method can give full play to the performance of the belt and prolong its service life.
The following table describes the representative phenomena of belts. Please refer to the countermeasures in the table below when a malfunction occurs.
Problem
Cause
Solution
Slippage
Belt tension slack
Give moderate tension
overload
Widen the belt or increase the number of belts
Small contact angle
Widen belt or idler with correct diameter of device
Stained with oil or water
Completely remove oil or water. Install the belt cover to prevent the adhesion of oil and water
Premature fracture
Load changes / suddenly overloaded . The transmission conditions used exceed the transmission capacity of the belt. The belt is not hung up according to the specified number; the specified belt shape is not used.
The design can be changed, but the hanging belt must be the specified belt shape and number (please use a higher-level belt according to the purpose)
Increase heat or increase bending fatigue (the diameter of the pulley is too small, the bending angle is too small, and the speed is too fast)
Take measures to reduce heat;
CHANGE THE DESIGN — change the pulley diameter, speed, and bending angle
Tension becomes loose and slips off
Give moderate tension
Cracked
Use at high temperature
Take exothermic measures
Tension becomes loose and slips off
Give moderate tension
Continuous emergency stop or emergency start
Change design
Stained with oil, etc.
Avoid oil adhesion and oil leakage
The pulley diameter is too small, and the back tension causes the reverse bending to be too strong
Change design
Direct sunlight
Attach the machine belt cover
Surface cracking
Tension pulley diameter is too small
Use a larger diameter tension pulley
The bending angle is too small
Relax the bending width
Tension becomes loose and slips off
Give moderate tension
Wear
The pulley groove is rusty or the surface of the pulley groove is rough
Evenly process the groove surface of the pulley
Tension pulley diameter is too small
Use a larger diameter tension pulley
The angle of the pulley device is incorrect; the shape of the pulley is abnormal, and the angle of the pulley groove is not accurate
Adjust the dislocation to below 1/3° , replace the pulley
Excessive vibration
The device of the machine body is unstable and resonates
Fix the device part
The belt tension is weak
Change the distance between axes
Belt length is not uniform
Use a consistent belt combination
Peel off
The transmission conditions used exceed the capacity of the belt
Hang the belt with the correct size, shape and number
Used in a deformed state, the method of use causes increased bending fatigue
Change design
Use noise
Emergency stop or emergency start
Change the design to make the belt run smoothly
Belt tension is too loose
Give moderate tension
overload
Widen the belt or increase the number of ribbed used
Machine belt selection error
Choose the belt shape and specifications that meet the operating conditions
ribbed belt flip
Not suitable for pulley groove angle and device angle
Dislocation aligned to the 1/3 ° or less
Adhesion of the machine belt due to damage to the pulley groove or rough processing surface
Replace the pulley
The belt length is not uniform when using multiple belts
Use a consistent belt combination

Advantage of conveyor belt in food industry
Advantage of conveyor belt in food industry
Conveyor belts have long been integral in manufacturing, packaging, and distribution facilities.
The food industry has long relied on industrial belt conveyors, mini conveyors, and rollers. These systems minimize human contact, reduce material handling, and make the overall food processing routine safer and more efficient.Conveyor systems come with some distinct advantages in food industry.
1. They Minimize Manual Labor.
2. Conveyor Belts Reduce Accidents and makes operation safer.
3.Conveyors Increase Food Safety and Quality.
Many newer conveyor systems keep products and foodstuffs free of contaminants by design.
Mini conveyors and conveyor belts are integral to the food industry. Items can move from one end of a processing plant to the other quickly, streamlining production.

The material of conveyor belt
The material of conveyor belt
They must be durable, long lasting and resistant to a wide range of temperatures, moisture and chemicals.
There are five main materials that conveyor belts are made out of: thermoplastics, metal, rubber, fabric and leather. Plastics include polyester, polyvinyl chloride, silicone and polyethylene. The metals are stainless and carbon steel, and the fabric materials are canvas or cotton. The most popular material is a rubber composite because it is flexible, resistant, smooth and seamless.
It also doesn’t have any holes or openings. To increase strength, many belt materials contain additives, including fabric, steel, polyester or fiberglass. Many flat belts are actually composed of a core material and a covering. These belts are parts of many different types of conveyors, including troughed, inclined, horizontal, food grade and overhead conveyors, but they are not used in chain, pneumatic or screw conveyors.
Choosing the right belting material is the most important specification involved with conveyor systems because the wrong material could compromise productivity or worker safety.
