Hot Vulcanizing Splice Air Cooling PVC Conveyor Belt Jointing Machine
How are conveyor belts joined?
Hot vulcanizing is the most ideal method of repair that uses both heat and pressure to join repair materials with compromised sections of the belt. ... Typically, the damaged portion of the belt is removed or trimmed down, and a new section is bonded in its place using an adhesive like glue or cement. When connecting conveyor belt ends together, there are mainly three commonly used joints: Steel buckle joints, Lap joints, and Tooth joints.
1. The steel buckle joint is a kind of joint method that can be disassembled repeatedly. The steel buckle joint has advantages and disadvantages. The advantage is that it can effectively avoid the inconvenience of installation after the conveyor belt is formed into an endless belt. The disadvantage is that it is not easy to clean, and it is easy to breed bacteria. It is easy to cause the conveyor belt joint to tear slowly, and the service life is short.
2. PVC conveyor belt cold bonding method is to use cold bonding adhesive to make joints. This joint method is more efficient and economical than mechanical joints, but from a practical point of view, because the process conditions are difficult to master, and the quality of the adhesive has a great influence on the joint, it is not very stable.
3. The toothed joint is the most common joint method for PVC conveyor belts, and it is also the strongest. The PVC conveyor belt is first layered and then toothed. Because the tooth is the same shape as the tooth, it is called a toothed joint. The toothed joint is fused together by high-temperature vulcanization of a Lightweight Green PVC Belt Vulcanizing Machine . Hygienic and easy-to-clean characteristics of conveyor belts.

Functions of Hot Vulcanizing Splice Air Cooling PVC Conveyor Belt Jointing Machine
• Splice pressure is applied by an internal compressor, max. 2 bar (28 psi)
• Heats up to a splice temperature of max. 200°C (392°F)
• Keeps it at the splice temperature (adjustable dwell time)
• Cools down to the cooling temperature (safe temperature to take the belt out)
• For thicker belts a preheat temperature and preheat dwell time can be applied
• The bottom heating can be set lower or higher than the top heating
• The splice surface is 130 mm ; the heated zone is 110 mm.
Introduction of Hot Vulcanizing Splice Air Cooling PVC Conveyor Belt Jointing Machine
If the belt is relatively thick a problem might occur where the outside of the belt is at the splicing temperature too long, waiting for the inside to reach the required temperature. Molten material might flow away or discolor and fabrics might shrink. To avoid this problem from happening, the preheat option can be used. This option heats the belt up (outside and inside) to a temperature just below the melting temperature. After the preheat stage, the inside splice temperature can be reached much quicker, minimizing the risk for unwanted flow of material, discoloring or fabric shrinkage.
The reading of the display relates to the top temperature of the press. If more or less heat is required at the bottom of the belt, the “bottom heat factor” can be used. Please note that this factor relates to a plus or minus amount of heat (%), not to a specific temperature.
