The servo feeder is precisely fed by the automatic servo control system, and the servo feeder is driven by the eccentric wheel, the connecting rod and the one-way device, etc., the roller rotates periodically, and the material is transported intermittently at a certain speed.

Therefore, the probability of material retreat in the machine itself will be relatively low. In many cases, it is caused by the operator’s wrong operation, such as the wrong angle of relaxation. If the angle is too large, the gap between the feeder roller and the material will be too large, resulting in no pressing force and the material will go back.

Another point worth noting is that due to the long service life of the servo feeder, the aging and wear of internal parts, and the various failure reasons caused by garbage and foreign matter, the material goes back.

The above are some of the reasons that Henli summed up based on previous cases that caused the material of the servo feeder to retreat. I hope it will be helpful to everyone.
