[0002] At present, sanders are mainly divided into vertical stirring sanders, horizontal disc sanders, horizontal pin sanders, etc., which are widely used in coatings, inks, pesticides, mining, ceramics and other industries. At present, sanders mainly have technical problems such as high energy consumption, low efficiency, high temperature, and low grinding quality. With the widespread application of new energy and nano materials, higher requirements are put forward for the grinding quality, grinding efficiency and working life of sanders.

[0003] The sander needs to be equipped with a grinding device to grind the material, so the grinding device is the key to the sander. The grinding device needs to be connected to the spindle drive, and a seal is required to separate the spindle drive component and the grinding component. The sander spindle in the prior art has a poor sealing effect on the internal structure, which causes the material to penetrate into the spindle during the grinding process, resulting in problems such as spindle damage. The overall sealing effect is not good and the practicality is poor. Utility Model Content
