Shoemaking sewing machine

Abstract

The invention relates to a shoemaking sewing machine. The shoemaking sewing machine comprises a worktop, and a handpiece which is arranged on the worktop; the handpiece comprises a presser foot which is opposite to the workbench top and has an adjustable distance; a fixed leg which can rotate around the axis of the presser is arranged on a position, near the presser foot, of the worktop; the peripheral distance from the center of the presser foot to a fixed shaft is the distance from a side edge of a sole to a seam of a shoe upper and the sole; when the shoe upper and the sole are sewn, a side edge of the sole to be sewn is adhered to the periphery of the fixed leg; in the sewing process, when the sole is pushed forwards, the distance from the edge of the sole to the center of the presser foot cannot be changed because of the limit of the fixed leg, so the shoemaking sewing machine ensures that the distance between the suture of the whole shoe upper and the sole and the edge of the sole is consistent; and the fixed leg is pushed by the sole to rotate and provide driving force for the side edge of the sole contacted with the fixed leg, so that the sole can be pushed forwards easily and quickly, and sewing efficiency is improved.

Description

technical field [0001] The invention relates to a shoemaking sewing machine for sewing soles and uppers. Background technique [0002] We know that various slippers on the existing market are mostly formed by sewing the upper periphery and the sole together. The sewing tool adopts a sewing machine similar to sewing clothes, that is, a shoe-making sewing machine. The difference of the sewing machine is that the height of the presser foot is higher relative to the work surface, and the sewing needle is thicker, which is determined by the thickness of the sole. When sewing, press the edge of the upper on the corresponding part of the sole, and then push the two together to the presser foot to drive the machine head to sew. Due to the curved shape of the shoe, it is often caused by improper control during the sewing process. The overall width from the edge of the sole to the seam of the upper is inconsistent, which not only affects the appearance of the shoe, but also is extrem...

When sewing, press the edge of the upper on the corresponding part of the sole, and then push the two together to the presser foot to drive the machine head to sew. Due to the curved shape of the shoe, it is often caused by improper control during the sewing process. The overall width from the edge of the sole to the seam of the upper is inconsistent, which not only affects the appearance of the shoe, but also is extremely inconvenient to operate and control
