Arphu brand vulcanizing equipment, it’s not only an ideal belt vulcanizing equipment in conveyor industry, but also reliable & safe. We offer Hot splicing conveyor belts and vulcanizing services for metallurgy, mining, coal, electric power, building materials, port, chemical and other industries.
Conveyor belt vulcanizing equipment, is also called the conveyor belt vulcanizer, hot splicing press, it’s a machine particularly used to joint the rubber & steel cord conveyor belts. the main body is made of high strength aluminum alloy. Common power supply, temperature uniformity, with a fully automatic electronic control cabinet, pressure systems supply 1.5 ~ 2MPa , the joint strength can reach the original belts 90 % or more.
The vulcanizer machine is widely used in metallurgy, mining, cement, power plants, ports, building materials, chemical industry, able to carry out conveyor belt hot vulcanizing and repairing effectively .
The vulcanizer 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)
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.
Maintenance of belt vulcanizing press
1) Before operating the machine, the insulation resistance of heating plates should be checked. If it is too low, the heating plates should be dried until the insulation value is up 50mΩ to meet the operation requirement.
2) During the operation or transportation, the machine should be handled with care.
3) If carry to field operation, the waterproof methods should be prepared in advance to avoid equipment damped.
4) After usage of machine, 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 sleepers under machine to avoid laying it on the ground directly, which is prohibited.
The quality of the conveyor belt joints directly affects the operation of the belt conveyor
Efficiency, if the joints quality are not high, It is easy to cause accidents such as hollow, pull-off or breakage of the joint head.
After years of groping and summarizing, we basically solved the problem of joint quality.
Pay attention to the following problems when bonding:
1. Heavy load belt conveyors must use hot vulcanization method
2. The splice length of the joint should be 1600-1800mm, as shown in below figure
generally divided into four grades, each grade 400- 450 mm, each layer of depth differs by a layer of canvas, overlapped in the direction shown.
3. The vulcanization temperature is 145℃±5℃, vulcanization time control at 36-38 minuets, don’t over 40 minuets, otherwise, excessive vulcanization will occur.
4. After the rubber joint is roughed, it must be cleaned and fully dried.
5. It should be melt the glue and stored 12 hours in advance.
Conveyor belt vulcanizer is a kind of vulcanizing equipment 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.
SUZHOU ARPHU INDUSTRIAL CO.,LTD, as one of the China’s leading conveyor belt vulcanizer company, we focus on the design, produce, sales, engineering technical consultation and project contracting of conveyor belt vulcanizing press (conveyor belt vulcanizer, hot splicing machine), belt repair vulcanizer, because we believe that the conveyor belt makes a real impact on the conveyor running and productivity. we will also focus on the quality management, creating an excellent technical service team, upgrading the service quality and realizing win-win integrity with customers.
