North pivoting device of industrial sewing machine

摘要

The disclosed contents enable the rotation force to be transmitted as a belt, and the horizontal installation structure of the drum is made to have a horizontal structure so that the connection with the thread sewn on the needle can be smoothly performed. In particular, And a defective ratio which is generated when a gap between the bottom surface and the main surface of the covering member is widened is improved, is provided.;The present invention relates to a twist pivoting device for an industrial sewing machine, in which a rectangular support 28, which is opened upward from a lower base 1, is fixed by bolting in order to support the inside of a cylindrical bar stock, A substantially quadrangular column having a side surface opened is placed in contact with the support table 28, and one side opening of the column is made to be detachable as a lid 25; The first tiltable member 22 is pivoted on the pivot axis line so as to pivot on the inside of the upper end of the frame 20 so as to be rotatable, north; And a second tiltable member (24) provided on a drive shaft (10) on the bottom surface of the base (1) for imparting a rotational force to the first tiltable member (22) to provide.
