The belt pressing of a belt conveyor is a key step in ensuring a secure connection and smooth operation of the belt. The following are several common methods of belt pressing: 
1、 Mechanical crimping method 
The mechanical crimping method is to connect the two ends of a belt together through a mechanical device. The specific steps are as follows: 
Articulate the two ends of the belt onto the pressure plate, ensuring that the hinges are flat, smooth, and defect free. 
Use mechanical devices such as tractors, marking machines, etc. to gradually press the two hinges together. 
During the crimping process, it is necessary to ensure uniform and stable force to avoid uneven force that may cause the joint to be unstable. 
The mechanical crimping method has the advantages of simple operation and low cost, but it has certain requirements for the material and thickness of the belt, and the strength at the joint is relatively low. 
2、 Hot pressing method 
The hot pressing method is to use thermal energy to melt the two ends of the belt and quickly press them together. The specific steps are as follows: 
Use heating devices such as hot air guns and soldering irons to heat the two ends of the belt. 
After hot melting, quickly press the two melted parts together and use a compactor to compact them, allowing them to cool and solidify together. 
The hot pressing method can make the joint more secure, but strict temperature control is required during the operation to avoid overheating or insufficient melting, which can lead to poor joint quality. 
3、 Chemical bonding method (cold bonding joint) 
Chemical bonding is the use of special adhesives to bond the two ends of a belt together. The specific steps are as follows: 
Process both ends of the belt, such as grinding, cleaning, etc., to ensure a clean and smooth contact surface. 
Apply the adhesive evenly on the joint surface to avoid excessive use of adhesive that may cause overflow or gaps in the joint. 
Press the two joint surfaces together and use a compactor to compact them. Then wait for the adhesive to dry and solidify. 
The chemical bonding method is easy to operate and has high strength at the joint, making it suitable for belts of various materials. But it requires the use of specific adhesives and strict adherence to operating procedures. 
4、 Mechanical connection method 
The mechanical connection method is to connect the two ends of the belt together through mechanical connectors. The specific steps are as follows: 
Clamp the two ends of the belt separately in mechanical connectors, such as steel wire clamps, steel wire rope clamps, etc. 
Adjust the tightness of the mechanical connectors to clamp the two ends of the belt and form a connection. 
The mechanical connection method is easy to operate, but the selection and use of connectors must comply with regulations to avoid damage to the belt. 
5、 Hot vulcanization joint 
Hot vulcanization joint is currently one of the most advanced joint methods. It uses a high-temperature and high-pressure environment to fuse the two ends of the belt with the vulcanized film, forming a whole. The specific steps are as follows: 
Pre treat both ends of the belt, such as grinding, cleaning, etc., to ensure that the joint is flat and free of oil stains. 
Place the vulcanized film at the belt joint to ensure a tight fit between the film and the belt. 
Heat and apply pressure to the joint using a vulcanizing machine to fuse the vulcanized film with the belt. 
After vulcanization is completed, cool down and check the quality of the joint. 
Hot vulcanization joints have the advantages of high joint strength, good stability, and long service life, but the operation process is relatively complex and requires professional vulcanization equipment and operators. 
In summary, there are multiple methods for belt pressing on conveyor belts, and the choice of method depends on the material, thickness, working environment, and specific requirements of the belt. In practical operation, it is necessary to strictly follow the operating procedures to ensure the quality of the joints and improve the operating efficiency and stability of the belt conveyor.
