Abstract
The invention discloses a punching sewing machine which comprises a body, a pair of pressing feet, a cuter and needles. The pressing feet are fixedly arranged at the bottom of the body; the cutter is arranged at the bottom of the body and correspond to a plurality of leakage holes, wherein the leakage holes are disposed on connecting pieces which are connected with the middle parts of the pressing feet; the needles are arranged on two sides of the cutter; two retractable rods are arranged on one side of the body; the retractable rods are fixed by a first fixing rod and a second fixing rod and slide synchronously; the first fixing rod is provided with a fixing part which is connected with the end parts of the needles; and the second fixing rod is provided with needle positioning holes. In the invention, due to the arrangement of the needle positioning holes, the problem that the needle of the traditional sewing machine can deflect so that the sewed textile has defects is solved.
Description
Technical field
The present invention relates to a kind of punching Sewing machines.
Background technology
Traditional dress makes that operator's qualification is very important in the process, faces machinist's famine, the raising of sewing device performance, and the dependence that garment production is broken away from operator's qualification is very important.Also be the problem always studied of sewing device expert for many years, tradition is made the dependence to operator's qualification, is mainly reflected in the gimmick and the consummate degree of operator's material processed in the process of making, and this also is the key that improves sewing output.Contents such as the attachment to a sewing machine of the introduction of our big length of front, special-purpose presser feet, operation model are important supplement to sewing device.Everything all is the standard sewing operation, make the result of study of operational standardization, sequencing, the appearance of automation, semi-automatic equipment is exactly the performance of these achievement in research mechanizations.But Sewing machines is owing to use for a long time, and pin can get loose because of some parts, and is fixing insecure, tends to cause the stitching of some fabrics to deflect like this.
Summary of the invention
For overcoming above-mentioned shortcoming, the object of the present invention is to provide a kind of punching Sewing machines that makes that the sewing needle location does not deflect.
In order to reach above purpose; The technical scheme that the present invention adopts is: a kind of punching Sewing machines; It comprises body, be fixedly set in a pair of presser feet of the bottom of described body, slide the bottom that is arranged at described body and with described presser feet in the middle of the pin that has the corresponding cutting knife of a plurality of small openings and be positioned at described cutting knife both sides on the brace that is connected with; One side of described body also is provided with two telescopic expansion links; Described telescopic rod fixes through first fixed bar and second fixed bar and slides synchronously; And described first fixed bar is provided with the fixed part that is connected with the end of described pin, and described second fixed bar is provided with the locating hole that can locate described pin.
Preferably, described telescopic rod is fixed in a side of described body through fixed cover.
Preferably; Also be provided with tension adjustment portion on the described body; And described tension adjustment portion comprises the nut of the end that tension adjustment sheet, the connecting rod with screw thread that is arranged at described tension adjustment sheet one side, screw thread that the supplied yarn that is oppositely arranged passes are arranged at described connecting rod, and be sheathed on the described connecting rod and be positioned at the spring in the middle of described tension adjustment sheet and the nut.
Preferably, also be provided with a plurality of adjacent guide parts on the described body, be formed with the groove that can supply yarn to pass on the described guide part.
Preferably, the two ends of described second fixed bar are fixedly connected through the end of connecting portion and described expansion link.
Owing to adopted technique scheme, be not difficult to find out that the present invention's setting of Sewing machines through locating hole of punching solves pin in traditional Sewing machines and can deflect and make the problem of stitching the fabric generation deviation of coming out.
