Sewing machine needle correcting device with transposition function

Abstract

The invention relates to the technical field of sewing machines, and discloses a sewing machine needle correcting device with a transposition function. The sewing machine needle correcting device comprises a needle rod, wherein the inner cavity of the needle rod is rotationally connected with a connecting pipe; an elastic ejector rod is inserted into the right wall of the needle rod in a sliding manner; a detection column is slidably connected to the right wall of the connecting pipe; a first spring is fixedly connected between the detection column and the right wall of the connecting pipe; ametal elastic piece is arranged on the right side of the detection column in the inner cavity of the right wall of the connecting pipe; and an extrusion column is slidably connected to the lower portion of the detection column in the inner cavity of the right wall of the connecting pipe. According to the sewing machine needle correcting device with the transposition function, a rotating ring is arranged and matched with the elastic ejector rod to fix a machine needle, then the detection column is arranged in a matching way to detect the orientation of the mounting surface of the machine needleand control starting and stopping of an electromagnet, and a rack can drive a transmission fluted disc to rotate through a transmission gear, so that the machine needle is more convenient to mount, and the situation of needle breaking and thread jumping in the sewing process is avoided.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine needle correction device with an indexing function. Background technique [0002] Machine needles, also known as sewing needles and car needles, are important components of sewing machines. There are hundreds of types of machine needles in China. In the sewing process, in order to achieve the ideal cooperation between machine needles, sewing materials and sutures, It is necessary to choose the appropriate machine needle. The working nature of the machine determines the selection of the machine needle. Different types of machines should be equipped with different types of machine needles. [0003] At present, since the needle clips for fixing the needles on the sewing machine are fixed at the right end of the needle tube, the user needs to face the sewing machine when installing the needle, and then rely on the right hand to rotate the needle clip to fix t...

Problems solved by technology

[0003] At present, since the needle clips for fixing the needles on the sewing machine are fixed at the right end of the needle tube, the user needs to face the sewing machine when installing the needle, and then rely on the right hand to rotate the needle clip to fix the needle. When the user is in other orientation positions of the sewing machine, it will be very difficult to fix the needle because the hands are not good enough to rotate the needle clip, and when performing daily sewing operations, the needle is often The model needs to be replaced. When the user’s negligence causes the flat surface and the curved surface of the end of the needle to be reversed, so that the curved surface faces the right side of the sewing machine, the needle will be broken and the thread will be skipped when the sewing operation is performed, which seriously affects the sewing machine.
