Abstract
The utility model relates to an sewing machine parts, the purpose provides kind of narrow limit rope inserted and repaiies tang presser foot, uses this presser foot to inlay the sewing of rope, has the quality easily controlled, quick efficient characteristics, technical scheme is kinds of narrow limit rope inserted and repaiies tang presser foot, including the depression bar that is used for connecting sewing machine presser bar and articulate the clamp plate in the depression bar bottom, characterized in that, is seted up on the bottom surface of clamp plate and is extended from front to back and with the guide way that inlays rope thickness and be fit for, the front side of clamp plate still extrudes to the right side in order to cut required reference point as the cutter.
Description
Technical Field
The utility model relates to an kinds of sewing machine parts specifically are sewing machine's cutter presser foot.
Background
However, the process has higher requirement, the finished embedded rope fabric 5 needs to be trimmed times (namely, a seam allowance is repaired; is operated on a cutter sewing machine), but the left side part of the embedded rope is convex, the lower part of a normal cutter presser foot is flat, the size of the seam allowance (the seam allowance is the allowance from 7 stitches to the cloth edge) is not easy to control, the processing effect is not ideal, and if manual trimming is adopted, the width is easy to be uneven, the speed is slow, and the efficiency is not high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming not enough among the above-mentioned background art, provide kinds of narrow limits and inlay the rope and repair the tang presser foot, use this presser foot to inlay making of rope, have the quality easily controlled, high efficiency's characteristics.
The technical scheme of the utility model is that kinds of narrow limit rope inserted seam allowance presser feet comprise a pressure lever used for connecting a presser foot rod of a sewing machine and a pressure plate hinged at the bottom end of the pressure lever, and the pressure plate is characterized in that the bottom surface of the pressure plate is provided with a guide groove which is extended from front to back and is suitable for the rope inserted thickness, and the front side of the pressure plate protrudes to the right side to be used as a reference point required by cutting by a cutter.
The cross section of the guide groove is arc-shaped, and the depth of the guide groove is -four fifths of the rope embedding diameter.
A spring is also arranged between the pressure lever and the pressure plate; the spring is vertically positioned at the junction of the pressure lever and the pressure plate and is positioned at the rear side of the hinge shaft.
The utility model has the advantages that the guide groove on the bottom surface of the pressing plate is utilized, so that the distance between the embedded rope and the fabric edge is ensured to be uniform (the recommended distance is 6mm) when the seam allowance is repaired, the product quality is obviously improved, the production efficiency is greatly improved (by more than 3 times), meanwhile, the requirement on the skill level of an operator is reduced due to the simplification of the operation requirement, and the ordinary worker can be trained for post operation.

Detailed Description
The present invention will be described with reference to the embodiments shown in the drawings, in which steps are performed.
The narrow-edge rope-embedded seam allowance repairing presser foot shown in the attached drawing comprises a pressing rod 1 for connecting a presser foot rod of a sewing machine and a pressing plate 2 hinged at the bottom end of the pressing rod (as can be seen from the figure, two hinge lugs 3 respectively provided with hinge holes are arranged on the upper surface of the pressing plate, the bottom end of the pressing rod extends into the middle of the two hinge lugs, and a hinge shaft 3-1 is inserted into the hinge holes on the hinge lugs and preset holes on the pressing rod so as to hinge the pressing rod and the pressing plate); a spring 4 is also arranged between the pressure lever and the pressure plate; the spring is vertically positioned at the junction of the pressure lever and the pressure plate and is positioned at the rear side of the hinge shaft. In addition, the needle hole 2-2 in the figure is only used for aligning the position of the needle when the presser foot is installed (the presser foot is installed on the cutter sewing machine), and the needle hole can not be arranged because the utility model discloses only carry out the tang and revise, need not the sewing (need not the needle operation).
The structure is similar to the existing cutter presser foot.
The improvement of the utility model is that the bottom surface of the pressing plate is provided with guide grooves 2-1 which extend from front to back and are suitable for the thickness of the embedded rope, so that the embedded rope 8 wrapping the cloth strip 6 outside can be embedded into the guide grooves, and can slide along the guide grooves to the rear side of the pressing foot under the pulling of the step-feeding rack of the sewing machine during operation, the pressing plate on the front side of the pressing plate (the left side of figure 1) protrudes a plurality of distances to the right side, and an operator can control the protruding part as a distance reference point during operation.
Preferably, the guide groove has a circular arc-shaped cross section, and the depth of the guide groove is -fourths of the rope diameter.
The working principle of the utility model is that the bottom surface of the pressing plate is provided with the guide groove extending from front to back, therefore, the fabric 5 with embedded ropes is sewn, the embedded ropes wrapped in the cloth strip can be to move forwards along the guide groove and can not slide out of the sewing machine when the seam allowance is repaired, and the edges of the fabric and the cloth strip can be cut by the cutter (in the prior art, positioned at the rear side of the pressing foot) arranged on the bedplate of the sewing machine to leave the seam allowance of the orderly-cut , thereby realizing the preset purpose.
Claims (3)
