Hot Vulcanizing Splice Air Cooling PVC PU Belt Jointing Machine

How many ways are there for PVC/PU conveyor belt joints?

There are basically three types of conveyor belt joints: mechanical joints, cold bonding joints, and hot vulcanization joints.

1. The mechanical joint method of PVC conveyor belt generally refers to the use of belt buckle joints. This joint method is convenient, convenient and economical, but the joint efficiency is low and easy to damage, 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 used for products below grade 8 belts.

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, and should be able to achieve better joint effects. However, from a practical point of view, due to the difficulty in mastering the process conditions, and the quality of the adhesive has a great influence on the joints. So not very stable.

3. PVC conveyor belt hot vulcanization jointing method Conveyor belt joint has proved to be the most ideal joint method in many years of actual combat, which can ensure high joint efficiency, and is also very stable, and the joint life is also very long and easy to master.

Detailed Images:

The splice press is an all-in-one solution for splicing thermoplastic conveyor belts (e.g. PVC polyurethane).

No external control box, air pump, or water cooling tank are required.

The presses are provided with electric heating and built in air cooling. The jointing process runs fully automated.

Functions of Hot Vulcanizing Splice Air Cooling PVC PU 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 PU 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.
