Rubber conveyor belt joiners (hereinafter referred to as conveyor belt joint machine), 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.
Conveyor Belt Joiners & Repairs
ARPHU can provide you with all your conveyor belt joints & repairs to keep your belts running with minimal interruptions.
1. Heating Plate: lightweight, portable, pressure and temperature uniformity;
2. Water Plate: high pressure can reach Max. 2.0 MPa (20 bars or 290 psi);
3. Cross Beam: lightweight & high tensile aluminum alloy.
Conveyor belt joint machine structure
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)
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 vulcanizing machine are made of aluminum alloy material, the feature of aluminum is smooth surface, high strength.
Water-cooled type vulcanizing machine will be greatly save the time. From the vulcanizing temperature to 60 ℃, it only needs 20 minutes.
Conveyor belt Vulcanizing equipment is ideal as it will reduce the wastage of conveyors belts as well as time.
Tips on how to improve the quality of the conveyor belt joints by conveyor belt hot splicing.
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.

Maintenance of Vulcanizer
Before operating the rubber conveyor belt joiner (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.
