Description

Technical Field

[0001] The utility model relates to the technical field of the hemming mechanism of a sewing machine, in particular to a hemming mechanism of a sewing machine. Background Technique

[0002] As is well known, a sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so as to interweave or sew together one or more layers of sewing materials. Sewing machines can sew fabrics such as cotton, linen, silk, wool, artificial fibers, bamboo products, etc., and products such as leather, plastic, and paper. The stitches sewn are neat, beautiful, flat and firm, with a fast sewing speed and easy use. Hemming is an essential process step during the sewing process of fabrics by a sewing machine.

[0003] During the processing of bamboo mats, in order to prevent the edges of the mats from being worn, hemming is usually carried out on the edges. Currently, hemming is usually done by manually holding a cloth strip, pressing one end of the cloth strip, and then pushing the mat, and hemming the mat with a sewing machine. However, during the hemming process, the staff needs to keep pressing the cloth strip with their hands to prevent the cloth strip from wrinkling, resulting in a complex operation process and low work efficiency. Content of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a hemming mechanism of a sewing machine, which solves the problems mentioned in the above background technique.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solution: A hemming mechanism of a sewing machine includes a fixing plate. Both ends of the fixing plate are provided with fixing holes. One end of the fixing plate is connected with a hemming component. Two fixing cylinders are connected to the top of the fixing plate. A sliding hole is provided on one side of each fixing cylinder. A slider is arranged in each fixing cylinder. A connecting rod is connected to the top of each slider. A pulling handle is fixedly connected to the top of each connecting rod. A spring is installed on the top of each slider. A sliding rod is arranged on one side of each slider. One end of each sliding rod is connected with a rotating shaft. Two limiting pieces are connected to each rotating shaft. A pressing wheel is installed on each rotating shaft.

[0008] Furthermore, the hemming component is arranged in a U shape and is provided with a through hole in the middle.

[0009] Furthermore, each slider and each fixing cylinder are connected through a sliding connection.

[0010] Furthermore, each connecting rod and each fixing cylinder are connected through a sliding connection.

[0011] Further, each slide bar is in the shape of a cuboid, and each slide bar matches each slide hole and is connected by sliding.

[0012] Further, each rotating shaft and each pressing wheel are connected by rotation.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present utility model provides a hemming mechanism for a sewing machine, which has the following

[0015] beneficial effects:

[0016] For the hemming mechanism of the sewing machine, a bevelling component is arranged on the fixing plate. The bevelling component is arranged in a U shape and has a through hole in the middle, which is convenient for the cloth strip to pass through and fit with the edge of the mat. A spring is installed on the top of the slider, so that the roller presses the hemming cloth strip. During the use process, as long as the staff pushes the mat, its hemming can be carried out, improving the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
