Air Cooling PVC Belt Splicing Machine

Factory Price Air Cooling PVC/PU Conveyor Belt Jointing Machine

Jointing with mechanical hot vulcanization is equivalent to 60%-80% of the strength of the conveyor belt itself.

How many joint methods are there for PU/PVC/PVG conveyor belts?

Belts delivered with no endless joints
Open length belt : the belt is cut at a right angle of 90 °
PPC/DS belt : the ends are prepared for a single finger on-site welding
PPC/DS/DEC belt : the ends are prepared for an on-site welding with an overlap finger splice
PPC/PE belt : the ends are prepared for an on-site welding with a step overlap
PPC/PE/DIAG belt : the ends are prepared for an on-site welding with a diagonal overlap splice

Belts delivered with endless splices
SF/DS belt : simple finger splice (straight through finger joint)
SF/DS/DEC belt : finger overlap splice (finger over finger joint)
SF/PE belt : step overlap splice
SF/PE/DIAG belt : diagonal step overlap splice

Conveyor belts equipped with a fastener (metal laces)
Plate Self Lock type fasteners (SL00, SL01 & SL02 types)
Fasteners with rivets (Steel and stainless steel)
Wire fasteners with round or flat wires
Plastic fasteners, ideal for metal detectors

Factory Price Air Cooling PVC/PU Conveyor Belt Jointing Machine 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.

What is the reason why PVC conveyor belt joints are easy to crack?

The reason why the PVC conveyor belt joint is easy to crack is that the cracking of the PVC conveyor belt joint will directly affect the use of the conveyor belt. Generally speaking, there are two factors that cause cracking of PVC conveyor belt joints.

The strength at the joint of the PVC conveyor belt is lower than that of the ordinary belt body. Under normal circumstances, when using mechanical connection, the strength of the joint can only reach 40-50% of the strength of the belt. When the cold glue quality is good, the joint strength can reach 60-70%, and the hot vulcanization strength can reach 80-90% (the joint method is correct and there is no quality defect).

Due to the low strength of the joint, if the bonding method is not correct, the strength of the joint will be low, such as cutting, injuring the next layer of cloth during grinding, excessive grinding, excessive lap length, and insufficient bonding performance. In use, the phenomenon of disconnection of the joint part is easy to occur. In addition, if the PVC conveyor belt does not use sealing glue, or the direction of the bonding head is wrong, the joint part is prone to cracking (surface rubber part)

Specification list

Functions of Factory Price Air Cooling PVC/PU 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 Factory Price Air Cooling PVC/PU 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.
