Description

Technical Field

[0001] This utility model relates to the technical field of sewing machines, and in particular to a template mechanism for sewing in a sewing machine. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on fabric, so that one or more layers of fabric are interwoven or sewn together. When it is necessary to sew the sewing threads together, a sewing machine template is required.

[0003] A sewing machine template structure generally includes a fixed template and a movable template. The movable template is rotatably connected to the fixed template via a shaft. The movable template has several sewing grooves, while the fixed template has several frame grooves. During sewing, the fabric to be sewn is placed between the fixed and movable templates. When the sewing machine starts working, the movable template rotates via the shaft. Because the sewing grooves on the movable template correspond to the frame grooves on the fixed template, the sewing needle can precisely sew along the trajectory defined by the sewing grooves and frame grooves.

[0004] When a sewing machine needs to change different templates to sew different threads, the existing moving templates and fixed templates are one-to-one. When different threads need to be changed, both the fixed template and the moving template need to be replaced, resulting in the production of a large number of fixed templates and moving templates, which is costly. Utility Model Content

[0005] The purpose of this invention is to provide a template mechanism for sewing in a sewing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewing template mechanism for a sewing machine, comprising a fixed template and a movable template, wherein the fixed template and the movable template are rotatably connected by a rotating shaft, and a template changing mechanism is provided on the movable template, the template changing mechanism comprising:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides, for example Figure 1-4 The sewing template mechanism shown includes a fixed template 1 and a movable template 2, which are rotatably connected by a pivot. The movable template 2 is equipped with a template changing mechanism, which includes an operating plate 3, a locking rod 4, and an elastic component 5. The movable template 2 has an installation groove, and the operating plate 3 is located inside the installation groove. The operating plate 3 has sewing grooves equidistantly spaced on both sides of the inner wall of the installation groove, and locking grooves equidistantly spaced on both sides of the operating plate 3. One end of the locking rod 4 slides through the inner cavity of the locking groove. The other end of the snap-fit ​​rod 4 is slidably inserted into the inner cavity of the snap-fit ​​hole. The elastic component 5 is set inside the moving template 2 to drive the snap-fit ​​rod 4 to move synchronously. The elastic component 5 can drive multiple snap-fit ​​rods 4 to move synchronously, so that the snap-fit ​​rods 4 can install and remove the operating plate 3. At the same time, by replacing the operating plate 3 with different sewing grooves, the fixed template 1 and the moving template 2 can be used continuously. When operating different sewing threads, the manufacturing cost of the template can be reduced by replacing the operating plate 3.

[0032] Specifically, the elastic component 5 includes a compression rod 51, a compression block 52, a compression plate 53, and a compression spring 54. The moving mold plate 2 has symmetrically formed compression grooves communicating with the snap-fit ​​groove. The compression rod 51 is located inside the compression groove and is slidably inserted into the inner cavity of the snap-fit ​​rod 4. Inclined grooves are formed on both sides of the inner wall of the snap-fit ​​rod 4. The compression block 52 is slidably inserted into the inner cavity of the inclined groove and is fixedly connected to the compression rod 51. An elastic groove is formed outside the compression groove, and the compression plate 53 is located inside the elastic groove. The compression plate 53 is connected to the compression rod... 51 is fixedly inserted and connected. A compression spring 54 is sleeved on the outside of the extrusion rod 51. One end of the compression spring 54 is fixedly connected to the extrusion plate 53, and the other end of the compression spring 54 is fixedly connected to the inner wall of the elastic groove. The compression spring 54 is always in a compressed state, so that the extrusion plate 53 can provide a stable elastic force to the extrusion rod 51. This allows the extrusion block 52 to apply a force to the locking rod 4 through the inclined groove, so that the locking rod 4 can extend into the interior of the installation groove, thereby realizing multi-point positioning and installation of the operating plate 3.

[0033] Furthermore, the elastic component 5 also includes a synchronization plate 55, a pull plate 56, a connecting plate 57, a magnet 58, and a rotating component 59. A synchronization groove is formed on the outer wall of the moving mold 2, and the synchronization plate 55 is located inside the synchronization groove. The synchronization plate 55 is fixedly connected to the pressing rod 51. A rotating groove is formed on the outer wall of the synchronization plate 55, and a rotating component 59 is disposed inside the rotating groove. The pull plate 56 is rotatably disposed outside the synchronization plate 55 via the rotating component 59. The connecting plate 57 is symmetrically fixedly connected to the outer wall of the moving mold 2 with the pull plate 56 as the center. The openings of the connecting plate 57 are opposite to each other to facilitate the rotation of the pull plate 56. The magnet 58 is embedded inside the connecting plate 57. The pull plate 56 and the magnet 58 cooperate with each other. The cross-section of the pull plate 56 is rectangular, and the cross-section of the connecting plate 57 is L-shaped. The pull plate 56 can be rotated... Part 59 can extend and retract a certain distance, so that when the locking rod 4 is installed on the operating plate 3, it can retract to fit the moving template 2. At this time, the pull plate 56 can be attracted by the magnet 58 by rotating 90°, thus maintaining the installation and locking state of the operating plate 3. When disassembly is required, the pull plate 56 can be rotated 90° in the opposite direction and pulled, so that the pull plate 56 is away from the moving template 2 and the synchronous plate 55 is moved, thereby pulling multiple extrusion rods 51. This causes the extrusion block 52 to drive multiple locking rods 4 to be synchronously stored inside the locking groove through the inclined groove. Then, the pull plate 56 can be rotated 90° again, so that it can be attracted by the magnet 58 again, thus maintaining the state of the locking rods 4 stored inside the locking groove, which facilitates subsequent disassembly and reinstallation operations.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
