Conveyor belt product classification
All conveyor belts must be connected into a ring before they can be used, so the quality of the conveyor belt joint directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly
The common methods of conveyor belt joint include mechanical joint, cold bonding joint, hot vulcanization joint, etc

Conveyor belt mechanical joint method: generally refers to the use of belt buckle joint
This joint method is convenient and economical, but the efficiency of the joint is low and easy to damage, which has a certain impact on the service life of conveyor belt products
In PVC and PVG whole core flame retardant and antistatic conveyor belt joints, this joint method is generally used for products below grade 8 belt

Conveyor belt cold bonding head method: cold bonding adhesive is used for joint
This joint method is more efficient and economical than mechanical joint
It should have a better joint effect
However, in practice, it is not very stable because the process conditions are difficult to master and the quality of adhesive has a great impact on the joint

Hot vulcanization joint method of conveyor belt: it has been proved by practice to be the most ideal joint method, which can ensure high joint efficiency, and is also very stable
The service life of the joint is also very long and easy to master
However, there are some disadvantages, such as troublesome process, high cost, long joint time and so on

Repair classification conveyor belt cold vulcanization repair
Cold vulcanization repair of conveyor belt
1
grind the damaged part of the conveyor belt with an angle grinder and tungsten steel grinding disc

2
according to the size of the damaged part of the conveyor belt, select the corresponding repair strip or strip of the conveyor belt with semi vulcanized layer (the repair strip or patch shall be at least 15~20mm larger than the damaged part)
INMET recommends using the repair strip or strip with semi vulcanized layer
For materials without semi vulcanized layer, it is recommended to deeply polish the bonding surface

3
brush the damaged part of the conveyor belt and the semi vulcanized surface of the conveyor belt repair strip with the belt adhesive, and then dry it for a while, and then brush it for the second time (dry it until it does not stick to your hands, generally for five minutes under normal temperature)

4
straighten the repair strip and stick it on the grinding surface of the conveyor belt, knock and compact it with a rubber hammer or compaction roller to drive out the air

Warm tips: if the ambient temperature is too low, it is recommended to use iodine tungsten lamp or hot air gun for heating for 0
5-1 hour
If the heating time is allowed to be extended appropriately, it will be conducive to the improvement of the strength of the bonding surface

Hot vulcanization repair of conveyor belt
1
according to the damage size of the conveyor belt, it shall be at least 15~20mm larger around the damaged belt, draw a cutting repair line, cut at a 45 degree angle, and peel off the damaged cover rubber
Pay attention not to damage the underlying cloth layer or steel wire layer during cutting

2
the damaged part of the conveyor belt shall be deeply polished with an angle grinder and a tungsten steel grinding disc
It is recommended to grind 3mm

3
pave the polished conveyor belt with fabric reinforcing layer or steel wire reinforcing layer, brush the reinforcing layer and damaged parts with thermal vulcanizing agent, cut the four edges of the unvulcanized core rubber into bevels, and brush and lay the thermal vulcanizing agent (the size of the unvulcanized surface rubber shall be consistent with the size of the damaged parts)

4
use the hot vulcanizing mender or vulcanizing machine to pressurize and heat vulcanization

Warm tips: the temperature of vulcanizer controller is controlled at 145— Between 150 ℃, when the temperature of the upper and lower vulcanization plates is stable, start vulcanization for 35~45 minutes
(depending on the thickness of the belt, each vulcanized plate can vulcanize about 1mm rubber every 4 minutes) release the water pressure of the vulcanizer when the temperature of the vulcanized plate drops below 70 ℃, and then remove the vulcanizer

Rapid spray repair of conveyor belt
The conveyor belt is quickly sprayed with repair materials
It has super adhesion, excellent wear resistance, excellent tensile properties, cohesive strength, tensile strength, peel strength, and good hardness, toughness and elongation
It is free from disassembly and heat vulcanization
It can quickly repair the scratch of the rubber conveyor belt on site
The repair cost is low and the time is short
It can avoid major losses caused by scrapping, replacement and long-time shutdown
It has good self leveling and bright appearance
It can not only quickly repair the damaged rubber conveyor belt and rubber products, but also pre coat a protective layer on the surface of the products
Moreover, the repaired conveyor belt can fully reach the service life of the new conveyor

Adjustment method when the belt conveyor is started, the motor current will be 5-6 times higher than the rated value, which will not only affect the service life of the motor, but also consume more power In the design of the system, certain margin will be left in the motor selection
The speed of the motor is fixed, but in the actual use process, sometimes it needs to run at a lower or higher speed
Therefore, it is very necessary to carry out frequency conversion transformation
SAJ frequency converter is a kind of equipment that can realize soft start of motor, achieve energy-saving speed regulation by changing the working frequency of conveyor belt, and provide equipment with overcurrent, overvoltage, overload and other protection functions

Precautions with the popularity of conveyor belts in industrial production, manufacturers pay attention to multiple varieties, high performance, lightweight, multi-function and long service life
In industrial production, it is particularly important to use the conveyor belt correctly
The following matters should be paid attention to in the use of the conveyor belt:
1
prevent the idler from being covered by materials, resulting in poor rotation, prevent material leakage from being stuck between the roller and the belt, and pay attention to the lubrication of the moving part of the conveyor belt, but do not oil the conveyor belt;
2
prevent the conveyor belt from starting under load;
3
if the conveyor belt deviates, take measures to correct it in time;
4
in case of local damage of conveyor belt, artificial cotton shall be used for timely repair to avoid expansion;
5
prevent the conveyor belt from being blocked by the frame, pillar or block material to prevent it from being broken and torn
