Full-automatic sewing machine with arbitrarily rotatable machine head

Abstract

The present invention discloses a full-automatic sewing machine with an arbitrarily rotatable machine head. The machine mainly comprises the rotating machine head, an upper rotating table, a pneumaticlifting slide table, a machine frame, an X-direction driver, a Y-direction driver, an operation box, a tabouret driving motor, a machine head support, a rotating shuttle, a lower rotating table, an upper current collecting slip ring, a lower current collecting slip ring, an upper rotating table motor, a lower rotating table motor and an operation box support arm, wherein the pneumatic slide tablecomprises an air cylinder, a profile base, a sliding block and a sliding rail; and the upper rotating table is mounted on the machine head support through an inlaid nut and four M6 inner hexagon screws and then is mounted on the sliding block of the pneumatic slide table through eight M6 inner hexagon screws. The machine overcomes the defect in solving the stitch consistency problem in the priorart; the current collecting slip rings are added, so that the function of arbitrary rotation in the full-angle range can be realized, the reciprocating rotation in the fixed rotation range is avoided,and the efficiency is improved; and the machine head can be lifted, so that the machine is suitable for thin and thick material sewing.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a full-automatic sewing machine whose head can rotate arbitrarily. Background technique [0002] At present, the main products in the market are fully automatic template sewing machines. Since the rotary hook of the current machine head is fixed, when the sewing contour is curved, the movement of the needle shuttle and the direction of the contour cannot be guaranteed to be consistent, resulting in inconsistent and unsightly stitches. In order to always ensure positive stitches when sewing curved contours, it is necessary for the head hook to rotate with the contour, and the appearance of the rotating head solves this problem. By electrically controlling the rotation of the rotary table motor, the direction of the machine head is always consistent with the tangent direction of the current stitch outline, so that the stitches are consistent and beautiful. It is an urgently needed au...
