the common methods of conveyor belt joints are: mechanical joints, cold bonding joints, hot vulcanization joints, etc

1. Mechanical joint method of conveyor belt:

generally refers to the use of belt buckle joint. This joint method is convenient and economical, but the efficiency of the joint is low and easy to be damaged, which has a certain impact on the service life of conveyor belt products. In PVC and PVG whole core flame retardant and antistatic conveyor belt joints, this joint method is generally adopted for products below grade 8 belt

2. Cold bonding joint

that is, cold bonding adhesive is used for joint. This joint method is more efficient and economical than mechanical joint, and should have better joint effect. However, in practice, it is not very stable because the process conditions are difficult to master and the quality of adhesive has a great impact on the joint

among the well-known adhesives in China, shengka sk811 conveyor belt glue and huangshide ldj243 series conveyor belt glue are widely used in China

3. Hot vulcanization joint

conveyor belt joint has proved to be the most ideal joint method in many years of actual combat, which can ensure high joint efficiency, but also very stable, long joint life and easy to master. However, there are some disadvantages, such as troublesome process, high cost, long joint time and so on

extended data :

strength at conveyor belt joint:

1. The strength at conveyor belt joint is lower than that of normal belt body. Generally, when mechanical connection is used, the joint strength can only reach 40-50% of the belt strength. When the quality of cold glue method is better, the joint strength can reach 60-70%, while the strength of hot glue joint can reach 80-90% (the joint method is correct and there are no quality defects)

2. Due to the relatively low strength of the joint, if the bonding method is incorrect, the strength of the joint will be lower, such as cutting, damaging the next layer of cloth during grinding, excessive grinding, insufficient lap length, insufficient number of steps, poor performance or self sulfur failure of the rubber used for the joint, excessive grinding of steel wire rope, rust of steel wire rope, etc. the strength of the joint will be greatly reduced. When in use, It is easy to be disconnected at the joint

are generally three types

1. Mechanical joint – buckle joint

advantages: easy to maintain and connect

disadvantages: short service time, easy to damage the drum and deviate

2. Cold bonding – tear the two ends of the belt apart, apply glue, and then compact for 2 hours

advantages: convenient connection

disadvantages: the service time is longer than that of mechanical joints, and materials are easy to enter at the joints, which shortens the service life

3. Hot vulcanization joint – Tear both ends of the belt apart, apply glue, and then use a special vulcanizer for hot vulcanization

advantages: long service time, and the strength at the joint is basically the same as that of the whole belt

disadvantages: special connector tools must be used

generally, there are several common methods for belt joints, such as mechanical joint, cold bonding joint, hot vulcanization joint and so on

1. Mechanical joint refers to the use of belt buckle joint. This joint method is convenient and economical. If the belt is damaged in the process of use and you want to replace a new belt, this belt buckle joint is easy to replace, but the efficiency of the joint is low and easy to be damaged, which has a certain impact on the service life of conveyor belt products

2. Cold bonding joint refers to the method of using cold bonding adhesive to connect the two ends of the conveyor belt with adhesive as raw material. The key to the cold bonding effect depends on whether the glue used is seamless or not. Because this method has the advantages of high joint strength, no noise, no vibration, simple operation and short joint time, it is widely used. However, in practice, it is difficult to master the process conditions and the quality of adhesive has a great impact on the joint, so it is not very stable. In addition, the cold adhesive conveyor belt is not suitable for wet and temperature required materials

3. Hot vulcanization joint, the conveyor belt interface of the hot vulcanization joint is completely closed and is not easy to be soaked by water. The process of belt vulcanization joint is generally to place the lower frame of the vulcanizer on the belt frame, align the two ends, and then put the water pressure plate, small heat insulation plate and lower heat insulation plate in turn. Install and fix a 1-2m platform on both sides of the two vulcanizers. The upper surface of the platform should be flush with or slightly lower than the upper surface of the lower heating plate. At the same time, it can not affect the tension of the pull rod. Put the two joints of the belt on the platform to start vulcanization. This method is the most ideal joint method at present, which can ensure high joint efficiency, and is also very stable. The joint life is also very long and easy to master. However, the hot vulcanization joint process is complex, has high requirements for personnel, and the cold bonding process is simple. You can work after short-term training.

belt bonding method: conveyor belt and commonly known as belt, all conveyor belts must be connected into a ring before they can be used, so the quality of conveyor belt joint directly affects the service life of conveyor belt and whether the conveyor line can run smoothly. The common methods of conveyor belt joint include mechanical joint, cold bonding joint, hot vulcanization joint, etc.
conveyor belt mechanical joint method: generally refers to the use of belt buckle joint. This joint method is convenient and economical, but the efficiency of the joint is low and easy to be damaged, which has a certain impact on the service life of conveyor belt products. In PVC and PVG whole core flame retardant and antistatic conveyor belt joints, this joint method is generally adopted for products below grade 8 belt.
conveyor belt cold bonding head method: cold bonding adhesive is used for joint. This joint method is more efficient and economical than mechanical joint, and should have better joint effect. However, in practice, it is not very stable because the process conditions are difficult to master and the quality of adhesive has a great impact on the joint.
hot vulcanization joint method of conveyor belt: practice has proved that it is the most ideal joint method, which can ensure high joint efficiency, very stable, long joint life and easy to master. However, there are some disadvantages, such as troublesome process, high cost, long joint time and so on

there are two types: cold sticking and hot sticking
