In the use of wood pellet machine, the skid of the press shaft is a common problem, which will not only affect the production efficiency, but also may lead to equipment damage. Here are some effective solutions:

1. Check whether the spindle is tightened

Reason: the tail of the spindle is not tightened or not tightened, resulting in the skid of the spindle during operation.

Solution: Remove the rear refueling system, remove the spindle gland, and check whether the butterfly spring is deformed. Then tighten the locking screw on the main gland and turn on the machine to check whether the spindle is shaking. If it is still shaking, you should remove the main gland, cushion the spindle with a copper rod, use a sledgehammer to push the spindle out in the direction of the ring die, and then remove the spindle seal cover to check whether the spindle bearing is intact. If the clearance is too large, the bearing should be removed and replaced with a new bearing, and then the main shaft should be installed in order to lock.

2. Check the roller gap

Reason: roller gap adjustment is not uniform.

Solution: Adjust the gap between the press roll to ensure that the gap between the press roll and the ring die is uniform to avoid excessive wear of the press roll.

3.. Check bearing lubrication

Reason: bearing lubrication is poor, resulting in increased friction, pressure shaft slip.

Solution: Check the bearing lubrication regularly to ensure that the bearing is fully lubricated. Choose the right lubricant or lubricating oil and use the correct lubrication filling method.

4. Check the bearing seal

Reason: the bearing seal is poor, resulting in wood chips and impurities entering the bearing inside, affecting the normal operation of the bearing.

Solution: Strengthen the sealing device of the bearing to ensure that the bearing chamber is strictly sealed to prevent wood chips and impurities from entering.

5. Check the eccentric shaft

Reason: eccentric shaft design is not reasonable or fixed, resulting in the shaft slipping.

Solution: Check the design and fixing of the eccentric shaft, and if necessary, redesign or fix the eccentric shaft.

6. Check the motor and drive system

Cause: Motor or transmission system failure, resulting in the skid of the press shaft.

Solution: Check the operation of the motor and transmission system, if there is an anomaly, timely maintenance or replacement.

Through the above steps, you can effectively solve the problem of wood pellet machine press shaft slip, ensure the normal operation of the equipment, improve production efficiency.
