Problems solved by technology

[0006] Therefore, the lubricating oil scattered inside the sewing machine arm passes through the thread member due to capillary phenomenon, and the lubricating oil reaches the thread cutting solenoid and drips to the bottom cover arranged under the base. Increased working hours and increased frequency of lubricating oil replenishment

Abstract

The invention relates to a sewing machine, being able to restrain leakage of lubricating oil. The sewing machine is provided with a linkage thread (62). The linkage thread (62) connects an actuator (31) that performs thread cutting of a thread cutting device and a thread release member (51) that switches the thread tension applying state of a thread adjusting device (5) to a release state. The linkage line is formed by a first thread (621) and a second thread (622), wherein one end of the first thread is coupled to a coupling member (64), and the other end is coupled to the actuator; one end of the second thread is coupled to the thread release member, and the other end is coupled to a coupling member; and the coupling member is configured to block penetration of the lubricating oil due tothe capillary phenomenon from any one of the first thread and the second thread to the other.

Description

technical field [0001] The present invention relates to a sewing machine with a thread release mechanism. Background technique [0002] In the existing sewing machine, in order to link the thread cutting and the release of the thread tension applied state by the thread regulator device, the plunger of the thread trimming solenoid that performs thread trimming and the release plate of the thread regulator device are used to connect the outer tube The inserted wire member (Wire) is connected, and the tension of the wire member is used to rotate the loosening plate by driving the plunger to activate the tension release lever of the wire adjuster device (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2013-212171 [0004] In addition, in order to prevent the leakage of lubricating oil in recent sewing machines, a gear box is installed on the base of the sewing machine, and a gear for transmitting the power of the ...
