Abstract

The invention provides a thread loosening device and a sewing machine with the same, wherein the thread loosening device is used for pressing or releasing a thread clamping device so as to enable thethread clamping device to realize thread clamping or thread loosening action. The thread loosening device comprises a thread loosening plate which is installed on the side of the thread clamping device and abuts against a thread clamping piece of the thread clamping device, and a thread loosening assembly which comprises a thread loosening ejector pin, the ejection end face of the thread looseningejector pin is opposite to the thread loosening plate, and at least a part of the thread loosening ejector pin is movably arranged relative to the thread loosening plate to push the thread looseningplate to move in the direction away from the thread clamping device so as to loosen threads, so that the problem that in the prior art, a thread loosening device is complex in structure is solved.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a thread loosening device and a sewing machine with the same. Background technique [0002] At present, the sewing thread will be entangled in the sewing process of the sewing machine, which is usually called a bird's nest. Therefore, most of the sewing machines are equipped with an anti-bird's nest device; the existing anti-bird's nest device will cause the sewing thread to be tight. The sewing thread is easily broken during the needle raising process, therefore, an auxiliary device is needed to loosen the thread. [0003] However, most of the existing auxiliary thread loosening devices have complex structures, occupy a large amount of installation space of the sewing machine, and reduce the installation efficiency of the operator. Contents of the invention [0004] The main purpose of the present invention is to provide a thread loosening device and a sewing machine with the s...
