Description

Technical Field

[0001] The present application relates to the field of sewing machines, and in particular to a sewing guide for a sewing machine. Background Art

[0002] A sewing machine is a device that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing material are interwoven or sewn together. It can sew fabrics such as cotton, linen, wool, and synthetic fibers, and products such as leather, plastic, and paper. It can be used in clothing production, household goods, textile manufacturing, leather products, and other fields.

[0003] When producing household items, hemming refers to turning the edges of quilts, sheets, pillowcases, etc. inwards before sewing to form a certain arc or fold, making the edges of the fabric neat, beautiful, flat and firm. When sewing, if the fabric is folded by hand and then sewn, it is difficult to control the folded area to remain stable, which can easily lead to deviations in the hem width after sewing.

[0004] Therefore, a crimping device is usually used to assist sewing. The crimping device includes a movable part fixed to the sewing machine table and a crimping member connected to the movable part. When in use, the movable part controls the position of the crimping member so that the crimping member is aligned with the sewing area of ​​the sewing machine. In related technologies, the distance between the crimping member and the movable part is adjusted by bolts.

[0005] When adjusting the sewing distance of the fabric, it is necessary to readjust the position of the hemming piece. At this time, the screw needs to be manually unscrewed, and then the position of the hemming piece needs to be adjusted. After the adjustment is completed, the screw needs to be tightened. The above steps for adjusting the hemming piece are relatively cumbersome, especially when sewing fabrics that need to adjust the hemming width multiple times, which may affect the sewing efficiency. Utility Model Content

[0006] In order to improve the efficiency of adjusting the position of a sewing guide, the present application provides a sewing guide for a sewing machine.

[0007] The present application provides a sewing machine sewing guide, which adopts the following technical solution:

[0008] A sewing guide for a sewing machine includes a curling movable unit and a curling unit, wherein the curling movable unit includes a fixed part fixed to the sewing machine table and a rotating part rotatably connected to the fixed part, and also includes a length adjustment unit, wherein the length adjustment unit includes a screw rod and at least one support block, each of the support blocks is fixedly connected to the top of the rotating part, each of the support blocks is provided with a threaded hole, the middle part of the screw rod is threadedly connected to the threaded hole, one end of the screw rod is installed on the top of the rotating part, and the end of the screw rod away from the rotating part is connected to the curling unit, and when the screw rod rotates, the screw rod drives the curling unit to move.

[0009] In the related art, the curling piece is the curling unit of the present application, and the movable piece is the curling movable unit of the present application.

[0010] By adopting the above technical solution, the hemming unit is used to flip the edge of the fabric inwards before sewing, so that the edge of the fabric has a neat, beautiful, flat and firm effect. The hemming unit can be driven to move by rotating the screw rod, and the distance between the hemming unit and the fabric can be controlled, thereby controlling the width and shape of the hemming, so that the sewing personnel can make flexible adjustments according to the hemming requirements to adapt to hemming processing of different styles and requirements. There is no need to fix the hemming unit by tightening the bolts, and the adjustment can be completed by simply rotating the screw rod. The fixing part can ensure that the sewing guide is stably installed on the sewing machine, and driving the rotating part to rotate can drive the length adjustment unit to rotate, thereby ensuring the accuracy of the hemming.

[0011] Therefore, the sewing guide of the present application has the function of conveniently adjusting the length of the curling edge, and has the characteristics of stability and flexibility. It can improve the quality and efficiency of the curling edge, make the curling edge smoother and firmer, and meet the curling edge width requirements of different fabrics. At the same time, when sewing, the screw rod can be rotated to adjust the distance between the curling edge unit and the fabric according to the curling edge requirements of different fabrics, so as to sew curling edges of different widths, or keep the position of the curling edge unit unchanged so as to sew curling edges of consistent width.

[0012] Optionally, a handle is provided at one end of the screw rod away from the crimping unit.

[0013] By adopting the above technical solution, the sewing personnel can easily rotate the handle to achieve the telescopic adjustment of the screw rod, and can accurately control the length of the hemming piece, making the length adjustment more convenient and intuitive. The sewing personnel can gradually adjust the screw rod through the handle according to the hemming needs, thereby changing the distance between the hemming unit and the fabric, which can meet the changing needs of sewing different fabrics. The support block can provide a stable support effect to prevent the screw rod from shaking or loosening, thereby maintaining the stability of the hemming piece.
