Sewing machine for automatically processing shoe sole line

Abstract

The invention relates to a sewing machine for automatically processing a shoe sole line, which comprises a workbench, a sewing machine main body, a sewing machine nose, a sewing machine needle and a sewing platform; the sewing machine further comprises a shoe sole motion driving mechanism, a shoe sole steering mechanism, a shoe sole input mechanism and a shoe sole output mechanism; the shoe sole motion driving mechanism comprises a first conveying roll wheel and a second conveying roll wheel which are arranged at the front part of the sewing machine needle; a gap for clamping the shoe sole isreserved between the first conveying roll wheel and the second conveying roll wheel, the first conveying roll wheel and the second conveying roll wheel are connected with a sewing machine spindle through a drive unit; when the sewing machine spindle is rotated, the first conveying roll wheel and the second conveying roll wheel are rotated in a reverse direction at the same time, thus the shoe soleis driven to move; the shoe sole steering mechanism comprises two guide wheels arranged at the upper part of the sewing platform; two guide wheels are located at the same height and the wheel axle isarranged in a vertical direction; there is an included angle which is not less than 90 degrees between the plane where the wheel axles of two guide wheels are confirmed and the wheel axle of the conveying roll wheel.

Description

technical field [0001] The invention relates to a sewing machine for automatically processing shoe sole threads. Background technique [0002] Traditional shoemaking is usually sewn with thread, and most of it is now replaced by gluing. And some high-end shoes still adopt sewing. The sole thread is a circle of thread sewn on the sole near the edge, which has the function of fixing the sole. There are two types of sole lines: open line and dark line, and the open line has a decorative effect in addition to fixing the sole. The existing processing mode of the sole line is that a sewing worker utilizes a common sewing machine to complete, and needs to constantly rotate the sole by hand during the sewing process, so that the sole line is sewn on the edge of the sole. This method of manually adjusting the sole not only affects the processing efficiency, but also makes it difficult to ensure that the distance from the processed sole line to the edge of the sole is consistent. ...
