1. Steel buckle connection method
Operation steps: Grind the two ends of the conveyor belt in layers, then put the two ends together and simply fix them with a hot air gun. Use special metal buckles to fix the two ends of the conveyor belt, and use special tools to pass the steel buckles through the conveyor belt and press and buckle them.
Applicable scenarios: Suitable for short conveyors or occasions where the conveyor is inconvenient to disassemble.
Advantages and disadvantages: Easy to operate, no complex equipment is required, and the connection can be completed quickly, which is suitable for emergency repairs or temporary splicing of production lines. However, stress concentration is prone to occur at the contact between the steel buckle and the conveyor belt, and long-term use may cause local wear of the belt body; and there are bulges at the joints, which are prone to vibration when passing through the roller, and may also scratch the equipment, affecting the smoothness of transportation.
2. Cold bonding method
Operation steps: Cut the conveyor belt into steps and roughen it as required, clean the surface with propylene copper, apply the mixture of SK313 and UT-R40 on the cut layer, apply it on both sides, tamp it evenly with a flat hammer, apply the mixture flat on the seam, apply pressure evenly, and place it for 24 hours before use. First, polish and clean the connection part, apply glue and press it tightly, and cure it at room temperature.
Applicable scenarios: mostly used in light load occasions with certain requirements for appearance flatness.
Advantages and disadvantages: low cost, relatively simple operation, and relatively flat joints. However, the performance of glue is greatly affected by ambient temperature and humidity. In humid and high temperature environments, the bonding strength will decrease; and the tensile strength of cold bonding joints is not as good as that of steel buckle connections, and it is not suitable for high tension, heavy load, and high-speed operation conditions.
3. Hot-melt connection method
Operation steps: Place the spliced conveyor belt on the hot-melt equipment and heat and pressurize it for hot-melting. The temperature is about 140℃. After the cloth layer reaches the insulation time, stop heating and let it cool naturally to room temperature. The conveyor belt can be used normally.
Applicable scenarios: Suitable for occasions requiring higher connection strength.
Advantages and disadvantages: The joint strength is high, the overall structure is neat, and the service life is long. However, the installation process requires professional hot-melt equipment and certain operating experience, and the installation is inconvenient.
4. Mechanical connection method
Operation steps: Use metal clips or clamps to clamp and fix both ends of the conveyor belt. Its structure is diverse, some are tightened by bolts, and some rely on buckle bite. It is easy to install and disassemble, and the length of the conveyor belt can be flexibly adjusted.
Applicable scenarios: Suitable for short-distance transportation with low connection strength requirements.
Advantages and disadvantages: Easy installation and disassembly, and the length of the conveyor belt can be flexibly adjusted. However, there is relative activity between the mechanical connector and the belt body, which is easy to wear the belt edge; if it is not fixed firmly, it may loosen during operation, causing safety hazards.
5. Toothed connector method
Operation steps: The conveyor belts of toothed joints are mostly thin belts, which are characterized by easy operation and fast hot melting speed.
Applicable scenarios: Suitable for the connection of thin belts.
Advantages and disadvantages: Easy operation and fast hot melting speed, but may not be suitable for thicker conveyor belts.
6. Layered meshing method
Operation steps: The layered tooth connection method is a commonly used method for connecting conveyor belts to ring-shaped PVC conveyor belts. It can improve the connection strength of conveyor belts and effectively prevent problems such as warping of conveyor belts.
Applicable scenarios: Suitable for the connection of ring-shaped PVC conveyor belts.
Advantages and disadvantages: It can improve the connection strength of conveyor belts and effectively prevent warping of teeth at the connection, but the operation is relatively complicated.
7. Layered overlap method
Operation steps: Layered overlap is mainly used for mid-splicing, on-site connection and thicker PVC conveyor belt ring connection. Its main feature is fast connection speed.
Applicable scenarios: Suitable for mid-splicing, on-site connection and thicker PVC conveyor belt ring connection.
Advantages and disadvantages: Fast connection speed, but may not be suitable for thin belts.
8. Steel clamp method
Operation steps: Different steel buckle conveyor belts are used according to different PVC conveyor belt thicknesses, different usage environments, and different situations. Its biggest advantage is easy installation and high efficiency.
Applicable scenarios: Suitable for connecting PVC conveyor belts of different thicknesses and different environments.
Advantages and disadvantages: Easy installation and high efficiency, but may not be suitable for all types of conveyor belts.
9. Plastic button connector method
Operation steps: Plastic fasteners are mainly used in certain specific occasions, such as replacement of metal flaw detection type transmission belts.
Applicable scenarios: Suitable for specific occasions, such as replacement of metal flaw detection type transmission belts.
Advantages and disadvantages: Suitable for specific occasions, but may not be suitable for ordinary conveyor belts.
