Precautions for an endless conveyor belt joint

PU PVC conveyor belt joint process as following:

Mark the dimension line: generally take the side of the tape as the benchmark when marking, keep the size consistent, the angle accurate, and the benchmark unified. Pay special attention not to mistake the oblique direction of the adhesive surface and the corresponding relationship between the upper and lower adhesive layers.

Ply separator and finger punching : use a belt ply separator machine to separate the upper and lower parts of the conveyor belt with the open end, and then use a belt finger punching machine to mark the divided conveyor belt with the upper and lower parts staggered.

Splicing: use a hot-air gun to splice and fix the punched fingers

Hot press integrated molding: put the fixed conveyor belt on the hot press machine for hot press fixed molding, so that the conveyor belt can be conected and used on the belt conveyor equipment.

Key issues needing attention in conveyor belt joint process:

The design and fabrication of the conveyor belt joint shall ensure that the whole belt is straight at the joint parts without bending, otherwise it will lead to the deviation of the conveyor belt and difficult to adjust.

The steps on the upper and lower sides of the joint ends shall ensure accurate alignment.

The whole bonding process shall be carried out on a flat plane to ensure the overall flatness of the joint.

Pay attention to the thickness relationship between the upper and lower layers when make the ply separation.

The reference edges at both ends need to be aligned with each other, otherwise the finger cannot be spliced.

During hot pressing, adjust the appropriate temperature according to different conveyor belts, otherwise the conveyor belt joints will not be firmly connected due to insufficient temperature.
