How to solve the problem of injection failure in slipper making machines
In the disc rotating PVC slipper making machine, when the machine completes feeding, the machine does not inject the raw material,How do we solve the problem of PVC slipper making machines not being able to inject.We analyze the reasons and solutions for reference only:
The machine must be power off before operation check!
Reason 1:FATEK PLC did not detect the boost signal.
Solution1:①Adjusting the position of the hydraulic pressure relay.②The oil seal of the oil cylinder is damaged or the hydraulic valve is stuck. Replace the oil seal or clean the hydraulic valve.③Check if the hydraulic relay is damaged. If it is, replace it.
Reason 2:Injection pressure or speed too low.
Solution 2:Adjusting pressure 60-75kg/cm2 and speed set 80 at the human-machine interface.
Reason 3:There is no set time for injection 1 and injection 2 on the human-machine interface.
Solution 3:Set injection 1 time for 3-6 seconds and injection 2 time for 1-3 seconds.
Reason 4:The nozzle is blocked by a small iron.
Solution 4:Open the injection nozzle and clean it.
Reason 5:The raw materials have burned inside the barrel.
Solution 5:Temperature decrease, cleaned the screw and barrel.
