Description

Technical Field:

[0001] The utility model belongs to the technical field of sewing equipment, and particularly relates to a presser foot structure and a sewing machine. Background Art:

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on a fabric, so as to interweave or sew together one or more layers of fabric. When sewing an elastic band on a fabric, since the elastic band has a certain elasticity, it is easy to curl up after sewing. At present, most sewing machines are equipped with an automatic thread cutting structure, that is, after sewing is completed, the controller controls the cutter of the thread cutting structure to act and cut off the elastic band and the sewing thread. Due to the curling of the fabric after sewing, the cutter may fail to cut the elastic band, the sewing thread or damage the fabric, which affects the working efficiency and increases the defective rate of the product. Summary of the Invention:

[0003] The purpose of the utility model is to provide a presser foot structure that can prevent the fabric from curling and facilitate the cutter of the thread cutting structure to cut off the sewing thread and the elastic band, and a sewing machine with the presser foot structure.

[0004] The utility model is implemented as follows:

[0005] One of the purposes of the utility model is to provide a presser foot structure, which includes a presser foot body, and a pressing plate is arranged on the rear side surface of the presser foot body, and the pressing plate can press the sewing material to prevent it from curling.

[0006] In the above-mentioned presser foot structure, the pressing plate and the presser foot body are of an integral structure.

[0007] In the above-mentioned presser foot structure, the pressing plate is in an L shape and includes a vertical plate and a horizontal plate. The vertical plate is attached to the rear side surface of the presser foot body and is fixedly connected to the presser foot body through fasteners.

[0008] In the above-mentioned presser foot structure, the pressing plate is made of metal material or plastic material.

[0009] In the above-mentioned presser foot structure, a fillet transition is provided between the vertical plate and the horizontal plate.

[0010] In the above-mentioned presser foot structure, the bottom surface of the pressing plate is higher than the bottom surface of the presser foot body.

[0011] Another purpose of the utility model is to provide a sewing machine, which includes the above-mentioned presser foot structure.

[0012] The utility model has the following prominent advantages compared with the prior art:

[0013] The structure of the utility model is simple. By setting a pressing plate on the presser foot body for pressing the material, the pressing area of the presser foot body is extended, preventing the fabric from curling after sewing the elastic band, facilitating the cutter of the thread cutting structure to cut the sewing thread and the elastic band, avoiding the situation of mis-cutting or empty-cutting and affecting the working efficiency, and improving the quality of the machine. Description of the Drawings:

[0014] Figure 1 is one of the schematic diagrams of the utility model;

[0015] Figure 2 is the second schematic diagram of the utility model.

[0016] In the figure: 1. Presser foot body; 2. Pressing plate; 3. Vertical plate; 4. Horizontal plate. Specific Embodiment:

[0017] The following further describes the utility model with specific embodiments:

[0018] Embodiment 1: Refer to Figure 1-2 :

[0019] This embodiment provides a presser foot structure, which includes a presser foot body 1. A pressing plate 2 is arranged on the rear side of the presser foot body 1, and the pressing plate 2 can press the fabric to prevent curling.

[0020] It should be noted that the rear side of the presser foot body 1 is the side where the fabric is conveyed outward after sewing.

[0021] The structure of the utility model is simple. By setting a pressing plate 2 on the presser foot body 1 for pressing the material, the pressing area of the presser foot body 1 is extended, preventing the fabric from curling after sewing the elastic band, facilitating the cutter of the thread cutting structure to cut the sewing thread and the elastic band, and avoiding the situation of mis-cutting or empty-cutting and affecting the working efficiency.

[0022] As one of the implementation manners, the pressing plate 2 and the presser foot body 1 of the utility model are of an integral structure. For example, the pressing plate 2 is welded on the rear side of the presser foot body 1. At this time, the pressing plate 2 can be L-shaped or a horizontal plate.

[0023] As another implementation manner, the pressing plate 2 and the presser foot body 1 of the utility model are detachably connected. Specifically: the pressing plate 2 is L-shaped and includes a vertical plate 3 and a horizontal plate 4. The vertical plate 3 is attached to the rear side of the presser foot body 1 and is fixedly connected to the presser foot body 1 through fasteners. Generally speaking, the fasteners are screws. Threaded holes are arranged on the presser foot body 1, through holes are arranged on the vertical plate 3 of the pressing plate 2, and the screws pass through the through holes and are screwed into the threaded holes to realize the installation of the pressing plate 2.

[0024] Generally speaking, the pressing plate 2 is made of metal material or plastic material.

[0025] In order to enable the fabric to easily pass between the presser foot body 1 and the platen 2, a fillet transition is provided between the vertical plate 3 and the horizontal plate 4, and the bottom surface of the platen 2 is smooth.

[0026] In addition, the bottom surface of the platen 2 is higher than the bottom surface of the presser foot body 1, and such a setting also facilitates the passage of the fabric.

[0027] Finally, it should be noted that the structure of the presser foot body 1 of the present utility model is not limited, and it is applicable to presser feet for different sewing requirements.

[0028] Embodiment 2:

[0029] This embodiment provides a sewing machine having the presser foot structure described in Embodiment 1.

[0030] The above embodiments are only one of the preferred embodiments of the present utility model, and do not limit the scope of implementation of the present utility model. Therefore, all equivalent changes made according to the shape, structure, and principle of the present utility model should be covered within the protection scope of the present utility model.
