  5. The stepping motor is damaged.
  6. The PLC did not send out a step pulse.
  7. The connection between PLC and the stepping driver is open, check whether the 2K resistor is open.
  8. Check if the wiring between the stepper motor and the driver is broken.
  9. The position proximity switch does not send a signal to the PLC.

Fault Four. The Main Motor of the Tea Bag Packing Machine with Line and Label Does Not Run

  1. The PLC did not send a signal to the inverter;
  2. The fuse of the main motor is blown
  3. Improper setting of the inverter;
  4. The middle relay under the electric control box is damaged or the circuit is disconnected.
  5. The inverter is damaged.
  6. The main motor is damaged.
  7. An error signal enters the PLC or the PLC is disturbed.

Fault Five.  There Is a Problem with the Cutting of the Inner Bag of the Tea Packaging Machine

  1. The cutter is blunt.
  2. The cutter adjustment is not enough.
  3. Not enough pressure.

Fault Six. The Label or Line of the Teabag Packaging Machine with Line and Label Is Not Cut

  1. Bad scissors.
  2. The scissors are not well adjusted.

Fault Seven.  The Outer Bag of the Tea Bag Packaging Machine With Line and Label Cannot Be Cut

  1. The cutter is blunt.
  2. The cutter adjustment is not high enough.
  3. Not enough pressure.
  4. The temperature can be appropriately increased without damaging the packaging film.

Fault Eight. After Pressing the Stop Button,  the Tea Bag Packaging Machine Cannot Be Stopped

  1. After replacing the PLC, the “stop position” is not set
  2. The touch screen is damaged.
  3. The inverter is damaged.
  4. The PLC is damaged and no stop signal is sent to the inverter.
  5. The buttons are not actually touched.

Fault Nine. the Bag Clamping Device of the Tea Packaging Machine Does Not Work

  1. The bag clamping and bag placement positions are not set.
  2. The air switch is not turned on.
  3. No output from PLC.
  4. The solenoid valve is damaged.
  5. The pneumatic clamp is damaged.
  6. The reaction speed of the pneumatic clamp cannot keep up with the mechanical speed.

Fault Ten. Bad Sealing of Label

  1. The temperature is not enough;
  2. Not enough pressure.
  3. The label is bad.

Fault Eleven. the Inner and Outer Bags of the Tea Packaging Machine Are Longitudinally Sealed Unilaterally

  1. Poor shaper or internal force is blocked;
  2. The shaper is not well adjusted.
  3. When the packaging film is installed, it is not aligned with the center axis of the former.

Fault Twelve. the Unloading Clutch of the Tea Packaging Machine Cannot Be Disengaged
