  • the present invention relates to a sander, and more particularly to a two-wheel sander that performs simultaneous positive and negative polishing.
  • BACKGROUND OF THE INVENTION Polishers are used in many industries and applications. The current polishing machine turntable is rotated in one direction. This structure not only has poor polishing effect, but also is not stable enough. Due to the reaction force of the polished object, the sander is always subjected to a single-direction force during operation, and it is necessary to manually fix its position, especially when the hand is operated for a long time, the user's hand may be fatigued. The same problem exists with the polishing machine.

Abstract

L'invention concerne une meuleuse à double roue et un polissoir à double roue comprenant un logement de tête (1), une coiffe d'extrémité (5) disposée à l'avant du logement de tête, et un moteur électrique fixé sur le logement de tête, le moteur électrique ayant une roue d'engrenage de rotor (6), la roue d'engrenage de rotor étant reliée à une roue entraînée vers l'avant (2) et une roue entraînée vers l'arrière (3), la roue entraînée vers l'avant étant reliée et fixée à un arbre principal (7), une extrémité de l'arbre principal étant reliée à une roue interne, la roue entraînée vers l'arrière étant reliée et fixée à un manchon d'entraînement interne (4), une extrémité du manchon d'entraînement interne étant reliée à une roue externe (9), une face d'extrêmité de la roue interne et une face d'extrêmité de la roue externe étant sur le même plan et pouvant tourner de manière concentrique dans des directions opposées. Les rotations vers l'avant et vers l'arrière de la roue interne et de la roue externe dans des directions opposées en même temps que la meuleuse à double roue et que le polissoir à double roue améliorent les effets d'abrasion et, étant donné que la force à action contraire provoquée lorsqu'un objet est poncé est automatiquement contrebalancée par la roue interne et la roue externe, la durée de vie de la meuleuse à double roue est prolongée tout en réduisant l'intensité de travail de l'utilisateur.
