JOINING INSTRUCTIONS USING HEAT GUN AND WELDING ROD |
|
The EPX range of polyester and polyurethane conveyor belting is manufactured from homogenous thermoplastic materials which
are easily joined using low cost equipment.
The essential equipment consists of a grooved steel or aluminium plate, clamps, hot air
gun with special nozzle, and a trimming knife, router or grinder.
The method is as follows: |
| 1) |
Align the belt ends, ensuring the belt is straight and true, cut ends 90 degree or at a 60 degrees angle for smaller pulleys. |
| 2) |
A 60 degree welding groove needs to be prepared by beveling the ends
30 degrees. |
| 3) |
Re-align and clamp the prepared ends
in position using a solid base and clamping bars right across both belt ends.
Leaving a 40 mm gap for welding is recommended. Two 100 mm packers next to the belt are also required. |
| 4) |
The next step is to fill in the V-groove
using the hot air gun with the special nozzle and a welding rod, adhering to the following
basic fundamentals: |
|
a)
|
Hot air gun temperature approximately 400 ° C |
|
b)
|
Keep a constant pressure on the nozzle. |
|
c)
|
Angle of the heat gun between 30 and 45
degrees. |
|
d)
|
Weld speed to be slow and steady. |
|
e)
|
Leave to cool to ambient temperature (5-10 minutes) |
| 5) |
Take away the clamps and remove the excess welding rod
using
a knife, die grinder or a router with a flat router bit. |
| 6) |
Cut the packers from the belt and remove excess weld
penetration from the underside, using a trimming knife. |
| 7) |
Try and break the packers, if they easily
break, start over from step 1. |
