Embodiment 1

[0026] Such as Figure 1-Figure 3 As shown, the sewing machine includes a casing 1 and a platen. The left end of the casing 1 is vertically pierced with a needle bar, and the lower end of the needle bar is fixedly connected with an organic needle. A thread take-up and passing mechanism of a sewing machine, comprising a thread hook 4, a thread take-up spring 8 and a right thread hook 7 all fixed on a sewing machine casing 1, and a left thread hook 2, a thread take-up Rod 3 and thread gripper 5. The thread take-up and passing mechanism of the sewing machine also includes a plate-shaped mounting seat 6 fixed on the casing 1, the right thread hook 7 and the thread take-up spring 8 are fixed on the mounting seat 6, and the right thread hook 7 is fixed on the bottom of the mounting seat 6. On the inner side, the inner side of the mounting base 6 refers to the side of the mounting base 6 opposite to the outer side of the casing 1 . The thread take-up spring 8 is fixed on the outer ...

Embodiment 2

[0030] The adjusting member 9 is a bolt, and the mounting base 6 is directly fixed on the casing 1 through the bolt. The mounting seat 6 is provided with a fixing seat on the right side of the rod body 8a, and the bolt is screwed on the fixing seat. The bolt is arranged transversely relative to the fixing seat and the rod body 8a can abut against the head of the bolt. Other structures are the same as in Embodiment 1. Bolt can limit excessive rebound when thread take-up spring 8 resets, prevents suture thread from being entwined into wire loop.

Abstract

The invention provides a take-up thread-guiding mechanism for a sewing machine and belongs to the technical field of sewing machines. The mechanism solves the problem of unsmooth thread guiding of anexisting take-up thread-guiding mechanism. The take-up thread-guiding mechanism for the sewing machine comprises a thread hook, a take-up spring and a right thread hook, the thread hook is fixed to asewing machine shell, and the take-up thread-guiding mechanism for the sewing machine further comprises a mounting base which is fixedly connected to the sewing machine shell; the take-up spring comprises a rod body in a long rod shape and a fixing end and a thread hooking end which are located at the two ends of the rod body respectively, the fixing end is fixedly connected to the mounting base,and the thread hooking end is used for thread guiding and located between the right thread hook and the thread hook; an adjustment component adjustable in position is further connected to the mountingbase, the adjustment component is located at one side of the rod body, and the rod body can abut against the adjustment component. The take-up thread-guiding mechanism has the advantages of smooth thread guiding and the like.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and relates to a thread take-up and passing mechanism of a sewing machine. Background technique [0002] A sewing machine is exactly a machine that sews sewing materials through sutures, including a needle bar mechanism, a thread take-up mechanism, a feeding mechanism, a hooking mechanism, a pressing mechanism, a thread clamping device and a lubricating device. The thread take-up and passing mechanism is to guide and transport the suture on the thread reel to the sewing needle, and cooperate with the needle bar mechanism to feed the suture. [0003] Chinese patent literature discloses a thread supply mechanism for sewing machines [Application No.: 201620466788.X; Announcement No.: 205636082U], which includes a thread take-up lever, a thread take-up spring and a thread clamp arranged in sequence along the feeding direction of the upper thread, There is a thread supply adjustment mechanism...
