welding ultrasonic geomembrane welding wedge welder
Welding machine introduction>>>
Geo-membrane welding machine is our new developed products, which can weld geo-membrane of various
thickness and are applicable for welding of all thermal-fused material such as LDPE, PVC, HDPE, EVA, PP
and so on.
Weding processing>>>

2. Main Components>>>
3.Operation principle>>>
Motor drives upper and lower pressure rollers to rotate through reduction gearbox and chain. Slide carriages
drive the hot wedge and insert it between the two base materials, at the same time lever presses pressure rollers
and engages the two fused base materials.

4. Replacement of components>>>
1). Replacement of hot wedge assembly
Remove the front end covering, remove the 4-M4 screws and tapping screw, remove a half housing, release 4-M3
screws, remove the 2-M5 screws that connect heating support and slide carriage, remove hot wedge and replace
with a new one, and reassemble the complete machine (shown as fig.6). Note: conform to color on wiring.
(Refer to fig.10 and text information)

3). Replacement of motor
Remove all screws on housing, remove front end covering to remove housing, remove the 4-M5 installation screws on
the support, remove the main chain guard and separate the upper and lower support. Remove the covering on the
bottom of upper support and weld connection between motor and fuse holder, screw off the 2-M5 installation screws of
the motor, take off motor and replace a new one. Weld back the removed wires and reassemble on the opposite sequence
(Note: keep upper and lower pressure roller is parallel during assembling.).
4) Replacing of upper and lower pressure roller
Remove the chain guard, take off the forcing off screws on the two chain wheels and then remove chain wheel and chain.
For upper rubber wheel, it can be removed if the two screws on bearing housing that on both sides of press plate are removed.
For lower rubber wheel, it can be removed if the bearing on one side of chain wheel. Reassemble them in the same method.
5. General troubles and eliminations>>>
Motor not run | Power off | Check that the mains is in On condition |
Fuse damaged | Replace fuse | |
Speed control circuit board damaged | Replace speed control circuit board or control box assembly | |
Motor burned | Replace motor | |
Motor speed can’t be regulated | Speed control knob is loosened | Tighten speed control knob |
Power tube disruption | Replace power tube or control box assembly | |
Hot wedge do not heat | Tubular electric heating element damaged | Replace hot wedge assembly |
Thermocouple failure | Replace thermocouple | |
Temperature control knob loosened | Tighten temperature control knob | |
Temperature control circuit board damaged | Replace temperature control circuit board or control box assembly | |
Hot wedge is burned red | Thermocouple failure | Replace thermocouple |
Controlled silicon disruption | Replace controlled silicon or control box assembly | |
Chain jumping | There may be sand or small stones on chain and gear | Remove sand or small stones |
6. Maintenance>>>
The complete machine should be cleaned, greased and placed in a dry place if it is not used. For PVC welding, the adhesions
on hot wedge should be cleaned off if it is not used longer than 4 hours to prevent wedge corrosion and service life being
shortened.
