Reasons for the Failure of Precision Leveling Machine And Troubleshooting Methods

Straightener is normally used for automatic press production, any defect happens to the straightener will affect the quality of the final product and delay the production progress.  Actually a lot of common problems can be solved in site to save time. Hong-Er summarized some common faults which may cause to the straightener below in aim to help you solve problems in site.

1. The Material Deviate its Direction.

Fault Cause: the feeding direction wasn’t right at the beginning causes the pressure not equal at the both side of the straightener.

Solution: take the material out of the straightener, adjust the pressure of both side, then re-feed the material correctly.

2. The Pinching Roller Can not Drive the Material due to Slip.

Fault Cause:the pressure for the pinching roller is not enough to press the material tightly.

Solution: adjust the material press spring on the pinching roller clock-wisely to increase the pressure.  

3 The Material Feeding Stops Earlier or Later.

Fault Cause:  the defer of the time relay inside the control cabinet not right.

Solution:properly defer the relay to match the speed of the feeder.

4 Sensor Out of Order.

         Fault Cause: 1.the sensor in poor contact or disconnected.

                              2.time relay or relay fault.

        Solution: 1. check the sensor circuit;

                       2.check the appliances in the control cabinet.

5.The straightening roller not working.

      Fault Cause & Solution: 1. the material thickness over range;

     2. Driving chain disconnecting;

     3. Motor start button or contactor fault;

     4. Shaft pin between the decelerator and motor disconnected;

     5. Motor circuit in poor contact or disconnected.
