Aluminum Foil Winding Machine mainly include Foil unwinding device, Feeding device, Cutting device, Correction System, Winding device, Welding device. in Previous article-(Failure Analysis of Automatic Foil Winding Machine) has introduced two parts.in the article will share the next seven parts.
3. Tension devise of Aluminum Foil Winding Machine
it includes a pair of polyurethane limb rubber rollers driven by an oil motor and an eccentric mechanism.
A pair of plunger cylinders rotate the mandrel of the upper roller.
Both ends of the mandrel installed with a pair of eccentric sleeves.
It can drive the upper roller to lift and press down.
When the two rollers press the foil belt and rotate forward and backward, the foil belt can be fed forward or backward.
The pressure of the adjustment system determines The magnitude of the tension.
4. Correction System:
the Correction System detection roller and the deviation adjustment valve control the fine adjustment deviation cylinder to push the swing frame.
the tension roller installed on the swing frame can correct the deviation by clamping the foil belt.
5. Shearing device of Aluminum Foil Winding Machine
if can’t shear, adjust the gap between the upper knife and the hob.adjust the tight pressure of the hob.
if the shear is not vertical, adjust the relative angle of the gears at both ends.
6. Winding machine:
the main shaft is driven by the frequency conversion motor through the worm wheel and worm shaft, and an oil motor assists the main shaft.
This oil motor is in communication with the oil motor of the tension roller.
When winding under working tension, the tension roller is pulled and rotated by the foil belt.
At this time, the oil motor on the tension roller is in the working state of the oil pump.
The oil motor can recover a part of the energy.
7. Winding roller pressure adjustment:
just twist the pressure spring screw
8. Welding problem:
We recommend the use of edge welding, which can reduce the current to more than 300 amps, otherwise excessive current will cause a series of problems.
9. Oil circuit system
oil circuit problem can leads to failure of correction system.
The two solenoid valves and correction cylinder must power on and power off at the same time.
If the front valve power on and the valve power off, the cylinder will continue to extend and cannot return.
Solenoid valve burnout problem:
Mostly the electromagnet is not sucked in place (caused by the spool is too long), you can add a gasket between the valve body and the solenoid valve.
Very nice post. I simply stumbled upon your weblog
