Abstract

The utility model discloses a needle bar cloth pressing device of a flat-end buttonhole sewing machine, which comprises a spring body, a cloth pressing bar, and a fixing ring. The utility model is characterized in that the U-shaped fixing ring is arranged at the upper end of the spring body, the L-shaped cloth pressing bar is arrange at the lower end, and the spring body, the cloth pressing bar, and the fixing ring are arranged into a whole; the fixing ring is vertically installed with the cloth pressing bar. The structure of the utility model is simple, the operation is convenient, when a needle bar vertical moves, the cloth pressing bar synchronously compacts elastic surface cloth which is required to be sewn, the sewing condition can be improved, the phenomena of skipping stitch and yarn break are effectively avoided, and the production efficiency and the product quality are enhanced.

Description

Tack seam eye eedle bar eccentric swage

Technical field

The utility model relates to the clothes processing technique field, especially a kind of tack seam eye eedle bar eccentric swage.

Background technology

Existing tack seam eye machine, in seam eye process, relying on presser feet need stitch the eye lining during needle sports compresses, stitch eye, this kind mode of making is that suture needle is moving, and presser feet is motionless, when running into elastic fabric, hollow lining, the numb soft lining seam of hair at the moment, phenomenons such as bouncing pilotage, broken string take place often, directly influence production efficiency and product quality.

Summary of the invention

The purpose of this utility model is a kind of tack seam eye eedle bar eccentric swage that provides at the deficiencies in the prior art, and it can avoid bouncing pilotage and broken string phenomenon effectively, has improved production efficiency and product quality simultaneously.

The concrete technical scheme that realizes the utility model purpose is:

A kind of tack seam eye eedle bar eccentric swage comprises spring body, compressing rod, retainer ring, and the spring body upper end is provided with U type retainer ring, the lower end is provided with L type compressing rod, and spring body, compressing rod, retainer ring are one.

Described retainer ring is vertical with compressing rod to be provided with.

The utility model is simple in structure, and is easy to use, and when shank moved up and down, the required elastic fabric of making of the synchronous compacting of compressing rod can improve the situation of making, and has avoided the phenomenon of bouncing pilotage and broken string again effectively, has improved production efficiency and product quality.

The specific embodiment

Consult Fig. 1, Fig. 2, Fig. 3, the utility model comprises spring body 1, compressing rod 2, retainer ring 3, and the top off-centre of spring body 1 is provided with the retainer ring 3 of inverted U, is provided with the compressing rod 2 of L type in the bottom of spring body 1; Plane intersects 90 degree at the plane at the U type place of retainer ring 3 and the L type place of compressing rod 2, spring body 1, compressing rod 2, retainer ring 3 are one.

Consult Fig. 4, when the utility model uses, spring body 1 is inserted in the suture needle and retainer ring 3 is fixed on the shank of tack seam eye machine, during work, when shank moves up and down, the compressing rod 2 of spring body 1 bottom moves up and down synchronously with suture needle, is making the elastic fabric that compressing rod 2 compacting at any time need be made in the process in suture needle under the effect of spring body 1, has avoided the phenomenon of bouncing pilotage and broken string.
