1, the method of the joints of the method of conveying belt joints are: mechanical joints, cold bonding joints, hot vulcanized joints, and so on several common methods. Mechanical joints generally refers to the use of belt buckle joints, this method is convenient and quick, but the efficiency is low, easy to damage, the conveyor belt products have a certain impact on the service life. In the PVC and PVG of the whole core flame retardant anti-static conveyor belt, the general level of the products are used in the following 8. Cold adhesive joints, that is, the use of cold adhesive to carry out joint. This approach is more efficient than mechanical joints, it is also more economical, should be able to have a better effect, but from the practice point of view, because the process is difficult to grasp, and the quality of the adhesive joints, the impact is very large, so it is not very stable. Heat vulcanization joints, the practice proved to be the most ideal one kind of joint method, can guarantee high joint efficiency, at the same time also very stable, joint life is also very long, easy to master. But there are some disadvantages, such as process trouble, high cost, long joint operation time and so on. 2, the joints of the conveyor belt can be used in accordance with the need of mechanical joints, cold bonding joints, hot vulcanized joints, such as joint method. General cold bonding joints, hot vulcanized joints to take the ladder type structural joints. 3, PVC and PVG core flame retardant conveyor belt joints due to the structure of the whole core belt is more special, the joint is not easy, so most of the use of mechanical joints approach, that is, the belt buckle joint. But more than 8 of the belt, in order to ensure that the effect of the joint, the general use of heat vulcanized joints. The structure of the joint is the joint of the finger. PVC and PVG core flame retardant conveyor belt of the heat curing process is more complex, the requirements of the device is also relatively high. 4, wire rope core conveyor belt conveyor belt of the joints is the most complex of all conveyor belt joint technology, not only complicated process, the design of the joints of the largest parameters. Different levels of product selection of the structure of the joints are different, the specific structure of the GB9770 standard.
