The belt sander is mainly used for wood polishing, which is a necessary machine for woodworking. If we operate improperly in the process of use, it will cause mechanical damage and shorten the service life of the machine. Today, we will discuss the common faults?
1、 Generally, due to improper adjustment, the normal belt swing should be 15-20 mm swing, 15-20 times / min swing frequency, moderate swing speed and consistent swing in and swing out speed. If it is in an abnormal state for a long time, deviation may occur, especially if the swing in and swing out speed is inconsistent, which is more likely to cause abnormal shutdown of woodworking sander; poor dust collection and high dust concentration will affect the normal operation of the photoelectric tube, and also cause belt deviation; the damaged parts of woodworking sander shall be replaced in time to improve the dust removal effect.

2、 There is no way to continue using the mechanical belt if it wrinkles. Generally, the reasons for wrinkling of the belt are as follows: abrasion of the sand roller and the tensioning roller, wrinkling caused by damp and softness of the belt, which can be treated by drying; when the machine is not used for a long time, the surface of the sand roller is easy to rust and rough, and the belt is difficult to swing, which causes various problems The roller shall be derusted or polished with fine sandpaper.
The above are the common faults of belt sander. I hope it can help you.
