Practice has proved to be the most ideal joint method, which can ensure high joint efficiency, and has a long joint life and is easy to grasp. The most important feature of this new type of vulcanization bonding technology is that the bonding effect is better, and the service life of the belt can be effectively improved.
Hot vulcanizer machine is a kind of vulcanizing device through stacking the two ends of the conveyor belt with the raw rubber material body in between, via heating device in which the raw material body is melted and the both ends of the conveyor belt are bonded together by a pressurization and heat retention process.
ARPHU brand conveyor belt jointing / patching machine adopts electric heating technology. It’s greatest advantage is that it is evenly heated by using rubber pressure plate, the machine works smoothly with uniform pressure. And it’s also equipped with portable automatic electronic control cabinet , which is easy to operate and has long operating life.
Practice has proved to be the most ideal joint method, which can ensure high joint efficiency, is also very stable, and has a long joint life and is easy to grasp. However, there are disadvantages such as troublesome process, high cost, and long joint operation time. The most important feature of this new type of vulcanization bonding technology is that the bonding effect is better, and the service life of the belt can be effectively improved without causing too much influence on the normal use of the belt conveyor machine. Since the service life of the tape joint is prolonged, the probability of failure in the normal operation of the conveyor machine is effectively reduced. It is suitable for conveyor belts with large transportation intensity, long distance and large load.
Hot vulcanizer machine structure
The hot vulcanizer machine is composed of the following parts.
1. Cross beam;
3. Iron plates for cushion;
7. High-pressure soft pipe;
8. Pressure-testing pump;
9. Heat-insulation plate;
10. Upper heating plates;
11. Secondary cable;
12. Electric control box;
13. Primary cable;
14. Down heating plates;
15. Hydraulic plates (please find Fig1 in detail)
Three three key factors that influence the conveyor belt joint quality are: vulcanizing temperature, vulcanizing pressure and vulcanizing time.
The main parts of conveyor belt hot vulcanizer machines are made of aluminum alloy material, the feature of aluminum is smooth surface, high strength.
Water-cooled type hot vulcanizer machine will be greatly save the time. From the vulcanizing temperature to 60 ℃, it only needs 20 minutes.
Conveyor belt hot Vulcanizer press is ideal as it will reduce the wastage of conveyors belts as well as time.
1. Vulcanization pressure: 1.0-2.0 MPa;
2. Vulcanization temperature: 145°C;
3. Difference in surface temperature of vulcanized plate: ± 5°C;
4. Heating up time ( at normal temperature to 145°C )<30 minutes;
5. Voltage: 220V/ 380V/415V/440V/480V/550V/660V, 50/60HZ, 3 Phases;
6. Temperature adjustment range: 0 to 199°C;
7. Timer adjustment range: 0 to 99 minutes.
Frequently Asked Questions
When heating, the temperature of the heating plate is not uniform, which may cause the joint to be intimately bonded. The following steps should be checked.
(1) Check whether the heat insulation plate is damaged or not, and this is an important cause of uneven heating temperature when the heat insulation plate is damaged;
(2) If the insulation plate is good, the heating plate can be heated separately, and then the thermometer is used to carry out the heating plate. If there is a problem, the internal heating sheet may be damaged. Contact the manufacturer to provide the heating element for replacement. Or return to factory for repair.
Maintenance of Hot Vulcanizer Machine
Before operating the vulcanizer, the insulation resistance of heating plates should be checked. If it is too low, the heating plates should be dried by energized until the insulation value is up 50mΩ to meet the operation requirement.
During the operation or transportation, the equipments should be handled lightly.
If carry the field operation task, the waterproof methods should be prepared in advance to avoid the equipments being spoiled.
After usage of the vulcanizer, it should be kept in the storehouse under the condition of less than 85% of relative humidity, and keep air circulation to avoid the erosion by rain or snow. Put the sleepers under the vulcanizer to avoid laying it on the ground directly, which is forbidden.
