Embodiment Construction

[0034] The rotary wire pulling device of the sewing machine of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] Figure 4 It is a front view of the assembly state of the rotary thread removal device of the sewing machine according to an embodiment of the present invention; Figure 5 It is an exploded perspective view of the rotary wire pulling device of the present invention; Figure 6 It is a side view of the rotary wiring device of the present invention. The rotary wire pulling device of the present invention mainly includes: a fixing piece, a fastener, a power generation mechanism, a power transmission mechanism and a wire pulling hook.

[0036] Such as Figure 4 and Figure 5 As shown, in order to allow the needle bar 180 and the sewing needle 182 to pass through, the above-mentioned fixing member 100 forms a ring (ring) shape with an open central part, its outer cylindrical surface has threads 102, and its t...

Abstract

This invention is related to a thread wiping device of sewing machine. This invention includes a fixing component that allows a needle rod to pass through a sewing needle and is combined at the lower part of a sewing head of the sewing machine; a fastening component combined at the fixing component; a power generating mechanism combined at the fastening component so as to generate the driving force; a power transmission mechanism connecting the power generating mechanism and transmitting the power; and a thread wiping hook that convolutes in a set angle along the driving of the power transmission mechanism. According to this invention, the thread wiping hook is enable to convolute in the set angle after the fastening component connecting with the thread wiping hook to rotate about the needed angle by using the needed rod as the center, therefore, the broken thread can be easily extracted from the sewing material in any direction so that the sewing quality is improved.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a rotary thread-wiring device of the sewing machine. Background technique [0002] figure 1 It is a perspective view of an embodiment of an existing sewing machine; figure 2 yes figure 1 Side view of the wiping device shown; image 3 yes figure 1 Front view of the wiping unit shown. The broken thread T in the sewing operation of the sewing machine M is an important factor affecting the quality of subsequent sewing. [0003] That is to say, if the length of thread T coming out of the needle hole of sewing needle 1 is too long, excess thread T will remain at the beginning of sewing and affect the appearance; on the contrary, if the length of thread T is too short, it will not be compatible with sewing. The initial bottom thread forms a tack and skips stitches. [0004] After the above-mentioned thread T is cut off, it is removed from the sewing product by the wire pulling device 2 . The...
