Spinning machine facilitating quick replacement of machine needle

Abstract

The invention discloses a spinning machine facilitating quick replacement of a machine needle. The spinning machine structurally comprises a machine body, a needle clamp, a presser foot, a base and ahand wheel disc; the bottom surface of the machine body is fixedly connected with the top surface of the base, and the hand wheel disc is installed at one side of the machine body. Compared with the prior art, the spinning machine has the advantages that there is no need to use an external tool, the replacement speed is high, the sewing progress is not affected, the installed machine needle can bekept perpendicular to a worktable, an operator does not need to hold the machine needle with one hand and conduct fixing operation with the other hand, the operation is more convenient, the hands canbe effectively prevented from being pricked by the machine needle, and the safety of installing the machine needle is greatly improved; the spinning machine can adapt to machine needles of differentneedle models and clamp the machine needles well, ensure that the installed machine needle is aligned with an opening seam of the presser foot, help to improve the spinning process and effectively prevent that the machine needle is misaligned and rigidly pressed broken by the presser foot.

Description

technical field [0001] The invention relates to the technical field of weaving, in particular to a weaving machine which is convenient for fast replacement of machine needles. Background technique [0002] The needle is an important component of the sewing machine. During the sewing process, the needle size must be selected according to the nature and thickness of the sewing material, so as to obtain a good sewing effect. Therefore, different needle sizes should be selected for sewing different fabrics. [0003] Most of the existing sewing machine needle clamps fix the machine needles by screws, so they have the following defects to be improved: [0004] 1) The screw fixing method can be realized by turning the screw with an external special tool when loading and unloading the machine needle. The tool is small and easy to lose or because the tool is forgotten. When the needle breaks or needs to be replaced, it will affect the The replacement of machine needles will affect t...

AI Technical Summary

Problems solved by technology

[0004] 1) The screw fixing method can be realized by turning the screw with an external special tool when loading and unloading the machine needle. The tool is small and easy to lose or because the tool is forgotten. When the needle breaks or needs to be replaced, it will affect the The replacement of machine needles will affect the progress of sewing;

[0005] 2) When installing the machine needle, it is necessary to hold the machine needle with one hand and turn the screw with the other hand, which is cumbersome to operate and the hand has been pierced by the needle tip;

[0006] 3) The larger the gauge of the needle, the thicker the needle, so the needle tip deviates from the seam opening of the presser foot, and it is easy for the needle to touch the presser foot when it is pressed down, causing the needle to break. After breaking, it is easy to splash the user. will cause harm to the user
