Description

Technical Field

[0001] The utility model relates to the field of sports floor processing, in particular to a grinding device for sports floor processing. Background Art

[0002] Indoor sports floors generally include professional sports wood floors, PVC plastic sports floors, acrylic (polyurethane) sports floors, rubber floors, etc. They are generally made of multi-layer structures, generally including wear-resistant layers (including UV treatment), glass fiber layers, elastic foam layers, base layers, etc. When processing sports wood floors, each piece of floor must be polished to ensure the good characteristics of the floor.

[0003] For example, the patent document with the announcement number CN220331469U discloses a four-sided planer for processing sports wood floors. After adjusting the motor drive, it can directly drive the threaded barrel to rotate. The threaded rod moves on one side under the fixation of the connecting rod. At this time, the connecting rod can pull the swing frame to realize the movement of the two sets of oppositely distributed movable seats, thereby changing the horizontal position of the transverse planer. In this way, the rapid adjustment function can be realized, which is convenient for cutting wood of different thicknesses. However, since the device uses vertical and horizontal guide rollers as the driving force for the workpiece to enter the planing and grinding operation, it is also a resistance to the workpiece when the planing and grinding operation rotates in the opposite direction. This resistance and power may cause the workpiece to slow down or even stagnate during planing. Utility Model Content
