Sewing machine capable of automatic processing sole threads

Abstract

The invention relates to a sewing machine capable of being used for processing sole threads. The sewing machine comprises a sewing machine body, a sewing machine head, a sewing machine needle and a sewing platform, wherein the sewing machine needle is arranged below the sewing machine head through a needle rod; the sewing machine further comprises a sole movement driving mechanism and a sole steering mechanism; the sole movement driving mechanism comprises a first conveying roller and a second conveying roller that are arranged in front of the sewing machine needle; a clearance for clamping asole is reserved between the first conveying roller and the second conveying roller; the first conveying roller and the second conveying roller are connected with a sewing machine main shaft through atransmission unit; when the sewing machine main shaft rotates, the first conveying roller and the second conveying roller rotate reversely simultaneously to drive a sole to move; the sole steering mechanism comprises two guide wheels arranged above the sewing platform; the two guide wheels are located at the same height; wheel shafts are arranged in a vertical direction; and an included angle between a plane defined by the wheel shafts of the two guide wheels and a roller shaft of each conveying roller is less than 90 DEG C.

Description

technical field [0001] The invention relates to a sewing machine capable of 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 consis...
