[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides an electric adjustment mechanism for adjusting the top rod of a blind stitch machine, such as Figure 1-Figure 4 As shown, it includes a motor 1, the output shaft 11 of the motor 1 is connected to a moving plate 7 through a transmission assembly, a shell 5 is installed on one side of the moving plate 7, the shell 5 is installed on a fixed seat 4, a push rod 6 is installed inside the shell 5, a guide channel and a push rod channel are provided in the middle of the shell 5, the moving plate 7 is slidably matched with the guide channel, and the shell 5 is slidably matched with the push rod channel. The output shaft 11 is driven to rotate by the motor 1, and then the power is accurately transmitted to the moving plate 7 through the transmission assembly, so that the moving plate 7 can slide stably and accurately along the guide channel in the shell 5. The sliding of the moving plate 7 drives the position change of the push rod 6 inside the shell 5, and the push rod 6 slides through the push rod channel in the shell 5, ensuring the stability and accuracy of the push rod 6 during the adjustment process.

[0028] This design not only realizes the electric adjustment of the top rod 6, greatly improving the efficiency and accuracy of the adjustment, but also reduces the friction and wear during the adjustment process through the sliding fit, thereby extending the service life of the mechanism. At the same time, the entire adjustment mechanism has a compact structure, a reasonable layout, and is easy to install and maintain, providing strong technical support for the automation and efficient production of blind stitch machines.

[0029] In this embodiment, the transmission assembly includes a first connecting rod 2 and a second connecting rod 3, one end of the first connecting rod 2 is fixed to the output shaft 11, the other end of the first connecting rod 2 is rotatably connected to the second connecting rod 3 through a bearing, the other end of the second connecting rod 3 is rotatably connected to the moving plate 7 through a bearing, and one end of the housing 5 is fixed to the moving plate 7. This connecting rod transmission design is not only simple in structure and high in transmission efficiency, but also can effectively convert the rotational motion of the motor 1 into the linear motion of the moving plate 7, providing a stable power source for the precise adjustment of the top rod 6.

[0030] Specifically, a limit rod 61 is installed at one end of the push rod 6, and a long groove 51 is provided on the outer wall of the housing 5 near the limit rod 61, and the limit rod 61 is slidably matched with the long groove 51. This design limits the moving path of the push rod 6 in the housing 5, ensuring the stability and accuracy of the push rod 6 during the adjustment process. At the same time, the design of the long groove 51 also provides a certain adjustment range for the push rod 6, meeting the requirements of different sewing processes.

[0031] Furthermore, a spring 62 is wound between the outer wall of the push rod 6 and the inner wall of the housing 5. This design not only makes the adjustment process easier and smoother, but also improves the stability and response speed of the push rod during the adjustment process, and enhances the dynamic performance of the entire adjustment mechanism.

[0032] Furthermore, a threaded end 63 is installed at one end of the spring 62, and an inner wall at one end of the housing 5 is provided with an internal thread, and the housing 5 is threadedly connected to the threaded end 63. This connection method is not only convenient for the installation and removal of the spring 62, but also ensures the stability and reliability of the spring 62 during the adjustment process through the self-locking characteristics of the thread, avoiding the adjustment error caused by the looseness of the spring.

[0033] Furthermore, the first connecting rod 2 is provided with a clamping opening near the output shaft 11, and the first connecting rod 2 is connected to the output shaft 11 through the clamping opening. This connection method is simple and reliable, easy to implement, and can effectively transmit the rotational power of the motor 1 to the first connecting rod 2, thereby driving the entire transmission assembly to work.

[0034] Furthermore, one end of the housing 5 is provided with an external thread, one end of the moving plate 7 is provided with a threaded hole, and one end of the moving plate 7 is threadedly connected to one end of the housing 5. This connection method not only enhances the connection strength between the housing 5 and the moving plate 7, but also can conveniently adjust the position of the housing 5 on the moving plate 7 through the adjustment function of the thread, thereby realizing fine adjustment of the position of the ejector rod 6.

[0035] Furthermore, the housing of the motor 1 is fixed to the fixing seat 4 by bolt connection. This connection method is stable and reliable, and can effectively fix the motor 1 on the fixing seat 4, avoiding the shaking and displacement of the motor 1 during operation, and ensuring the stability and accuracy of the entire adjustment mechanism. At the same time, the bolt connection also facilitates the installation and disassembly of the motor 1, reducing the maintenance cost.

[0036] Furthermore, the first connecting rod 2 is fixed by bolts at the clamping opening, so that the disassembly and assembly of the first connecting rod 2 is further facilitated.

[0037] Furthermore, the outer end of the ejector rod 6 is a flat structure, which further facilitates accurate ejection.

[0038] When the electric adjustment mechanism for adjusting the top rod of the blind stitch machine of the utility model is used, the motor 1 is first used as a power source to provide rotational power through its output shaft 11 .

[0039] The rotational power of the output shaft 11 is transmitted through the transmission assembly. The transmission assembly consists of a first connecting rod 2 and a second connecting rod 3, which are rotationally connected through a bearing. One end of the first connecting rod 2 is fixed to the output shaft 11 and rotates with the output shaft 11. The other end of the first connecting rod 2 is rotationally connected to one end of the second connecting rod 3 through a bearing, transmitting the rotational power to the second connecting rod 3. The other end of the second connecting rod 3 is rotationally connected to the moving plate 7 through a bearing, thereby converting the rotational power into the linear motion of the moving plate 7.

[0040] The movable plate 7 slides in the guide channel of the housing 5, and its linear motion drives the position change of the push rod 6 inside the housing 5. The push rod 6 slides through the push rod channel in the housing 5 to ensure its stability and accuracy during the adjustment process. A limit rod 61 is installed at one end of the push rod 6, and the limit rod 61 slides with the long groove 51 on the outer wall of the housing 5, further limiting the moving path of the push rod 6 and providing an adjustment range.

[0041] A spring 62 is wound between the outer wall of the push rod 6 and the inner wall of the housing 5, and the spring 62 provides assistance for the adjustment of the push rod 6, making the adjustment process easier and smoother. One end of the spring 62 is threadedly connected to the inner wall of the housing 5 through a threaded end 63, ensuring the stability and reliability of the spring 62 during the adjustment process.

[0042] One end of the housing 5 is provided with an external thread, which is threadedly connected to a threaded hole at one end of the moving plate 7. By rotating the housing 5, its position on the moving plate 7 can be easily adjusted, thereby achieving fine adjustment of the position of the push rod 6. The housing of the motor 1 is fixed to the fixing seat 4 by bolts, ensuring the stability and accuracy of the entire adjustment mechanism.

[0043] When the position of the push rod 6 needs to be adjusted, the motor 1 is started, and the motor 1 drives the output shaft 11 to rotate. The rotational power is transmitted to the movable plate 7 through the transmission assembly, causing it to slide along the guide channel of the shell 5. The sliding of the movable plate 7 drives the position change of the push rod 6 inside the shell 5, thereby realizing the electric adjustment of the push rod 6. During the adjustment process, the spring 62 provides assistance, and the sliding cooperation between the limit rod 61 and the long groove 51 ensures the stability and accuracy of the push rod 6. By rotating the shell 5, fine adjustment of the position of the push rod 6 can be achieved. The entire adjustment process is efficient and precise, and the mechanism structure is compact, easy to install and maintain.
