本发明涉及一种用于纸管的自动研磨装置，其在纸管的外表面上形成涂层并研磨涂层。 纸管自动研磨装置如下所述。 纸管的两侧由第一和第二支撑单元支撑并旋转。 研磨单元在纸管的纵向方向上从一侧到另一侧往复运动，以使用履带式研磨布自动研磨纸管的外表面。 旋转磨料以通过连续移动其研磨部分同时均匀地按压纸管的外表面进行研磨。 因此，本发明提高了加工性和生产率，提高了纸管的研磨质量。

The present invention relates to a paper tube outer tube automatic polishing apparatus for polishing smooth the coating layer after forming the coating layer on the surface, and more particularly to the support and rotated by the amount of the lateral branch pipe to the first and second support means, the grinding means but while reciprocate from side to side along the length of the branch pipe automatically polishing the outer surface of the branch pipe by a polishing cloth of a caterpillar form, referred to the polishing cloth is uniformly urges the outer surface of the tube is by well as rotating the polishing cloth of the polishing cloth Since operations while continuing to move the grinding adjustment part workability, improve productivity, has the characteristics as well as to provide the excellent quality of the grinding branch.
