Methods of joints There are several common methods for conveyor belt joints, such as mechanical joints, cold joints, and hot vulcanized joints.
Mechanical joints generally refer to the use of belt buckle joints. This joint method is convenient and quick, and economical, but the joints are inefficient.
It is easy to damage and has a certain impact on the service life of conveyor belt products. In PVC and PVG whole core flame retardant antistatic conveyor belt joints,
This type of joint is used in products with a class of 8 or less. Cold bonded joints, that is, cold bonded adhesives are used for joints.
This joint method is more efficient and economical than the mechanical joint, and should be able to have a better joint effect, but from practice
In view of the fact that the process conditions are difficult to master, the quality of the adhesive has a great influence on the joint, so it is not very stable.
The hot vulcanized joint has proved to be the most ideal joint method, which can ensure high joint efficiency and is also very stable.
The joint life is also very long and easy to grasp. However, there are disadvantages such as troublesome process, high cost, and long joint operation time. 2 minutes
Joints for layer conveyor belts Joints such as mechanical joints, cold bonded joints, and hot vulcanized joints can be used as needed. Generally cold
The bonded joint and the hot vulcanized joint adopt a stepped structural joint. 3. Joints of PVC and PVG whole core flame retardant conveyor belts
Because the structure of the whole core belt is special, the joint is not easy, so most of them use the mechanical joint method, that is, the belt buckle.
Connector. However, in order to ensure the joint effect, the belt of grade 8 or above is generally a hot vulcanized joint. Jointed
The structure is a finger joint. The hot vulcanization joint process of PVC and PVG whole core flame retardant conveyor belt is more complicated, and the requirements for equipment are also
Higher. 4. The joint of the steel cord conveyor belt The joint of the steel cord conveyor belt is the most complicated of all conveyor belt joint technology.
Not only is the process more complicated, but the joint size parameters are also designed the most. Different grades of products have different joint structures.
Please refer to the GB9770 standard for the specific structure.
