Embodiment Construction

[0031] The present invention will be described in detail below with reference to the drawings showing preferred embodiments. The directions of up and down, front and back, and left and right used in the following descriptions are in Figure 1 to Figure 7 Indicated by arrows.

[0032] Such as figure 1 As shown, a double needle sewing machine 10 includes a base 11 , a support 12 and an arm 13 . The base 11 has a flat upper surface extending in the horizontal direction. The pillar 12 is provided at the right end portion of the base 11 to stand upward. The upper part of the strut 12 supports the base end part of the arm 13 . The arm 13 extends leftward parallel to the base 11 . The arm 13 supports a main shaft (not shown) therein. The main axis extends in the left-right direction. The main shaft is driven to rotate by a sewing machine motor (not shown).

[0033] The double-needle sewing machine 10 has a needle bar 15 and a thread take-up lever 16 at the front end of an arm...

Abstract

The present invention relates to shuttle driving device of a sewing machine, wherein the arrangement space of two shuttles is adjusted through moving a shuttle seat. A shuttle driving shaft of the shuttle seat and a lower shaft in a base are sustained to a transmission state in the moving range of the shuttle seat. The shuttle seat is a small component configured in the base. An operator can easily adjust the arrangement space through moving the shuttle seat. The shuttle seat moves at a state when the connection between the shuttle driving shaft and the lower shaft is sustained. An operator can adjust the arrangement space of two shuttles at a state that the rotation positions of shuttles are unchanged.

Description

technical field [0001] The invention relates to a shuttle drive for a sewing machine with two shuttles inside a base. Background technique [0002] A twin needle sewing machine consists of two needles and two shuttles. Two machine needles are arranged on the front end of machine arm. Two shuttles are arranged inside the base. The two machine needles rise and fall under the drive of the upper shaft. The two shuttles are driven by the lower shaft to rotate synchronously with the raising and lowering of the needles. The double-needle sewing machine simultaneously forms double-line stitches on the processed cloth by raising and lowering two machine needles and rotating two shuttles. The two machine needles are arranged along the axial direction of the upper shaft inside the machine arm. The two shuttles are arranged along the axial direction of the lower shaft inside the arm. The stitch interval of the double thread can be changed by adjusting the interval between two mach...
