Technical Field

[0001] The utility model relates to the technical field of embroidery machines, and particularly relates to a thread rack device for an embroidery machine. Background Technique

[0002] An embroidery machine is a machine or mechanism for embroidery. When embroidery first separated from hand embroidery, the so-called embroidery machine at that time was not really an embroidery machine, because the embroidery machine at that time used a traditional sewing machine, replaced with a bottom plate with small round holes, the sewing machine needle continuously moved up and down, and coupled with holding the cloth tightened by an embroidery frame and moving back and forth. In fact, this so-called embroidery machine is still a kind of hand embroidery.

[0003] Chinese Utility Model Patent with Publication No. CN217378241U discloses a thread rack device for an embroidery machine. The thread rack includes a bottom plate, placing rods, support rods, a bracket, a wire guiding beam and a tensioning knob. A plurality of the placing rods are arranged on the top of the bottom plate, a bracket is arranged on the top of the support rod, and a plurality of the wire guiding beams are arranged inside the bracket. The device lacks a component for positioning the silk thread bobbin. During the embroidery process, the silk thread is continuously pulled, which may cause the silk thread bobbin to rotate and shake, and if the rotation amplitude is too large, it may cause the bobbin to break away from the placing rod, thus affecting the normal progress of the embroidery operation, resulting in low embroidery quality and economic losses.

[0004] Therefore, a thread rack device for an embroidery machine is proposed. Content of the Utility Model

[0023] As Figures 1 to 3 shown, a thread rack device for an embroidery machine includes a bottom plate 1. A plurality of equally spaced placement rods 2 are fixedly installed on the top of the bottom plate 1. Three circumferentially distributed slide rails 3 are welded to the outer wall surface of the placement rod 2. A limiting portion 4 for limiting the silk thread bobbin is slidably connected inside the slide rail 3. A rotating portion 5 for changing the spacing between the three limiting portions 4 is provided on the top of the placement rod 2;

[0024] Specifically, the three circumferentially distributed limiting portions 4 can limit and intercept the inner wall surface of the silk thread bobbin, avoiding the phenomenon that the silk thread bobbin disengages upward during rotation, ensuring the stability of the silk thread bobbin during use, effectively ensuring the normal development of embroidery operations, and guaranteeing the subsequent embroidery quality; the rotating portion 5 can change the spacing between the three limiting portions 4 to adapt to silk thread bobbins of different sizes, enhancing the practicability of the product.

[0025] As Figure 1 andFigure 2 As shown, the limiting part 4 includes a mounting post 401. The mounting post 401 is slidably connected inside the slide rail 3. A rotating cavity 402 is formed on the side wall surface of the mounting post 401. A rotating shaft 403 is rotatably connected to the upper and lower inner wall surfaces of the rotating cavity 402. A telescopic part 7 for pulling the mounting post 401 is arranged in the inner cavity of the slide rail 3. A protective pad 404 made of soft rubber material is bonded to the outer surface of the rotating shaft 403;

[0026] To ensure the fixing effect on the silk thread bobbin and prevent the silk thread bobbin from sliding upward to the upper end of the protective pad 404, anti-slip lines are provided on the outer wall surface of the protective pad 404, and the outer edge of the protective pad 404 is located outside the outer edge of the mounting post 401;

[0027] Specifically, the provided protective pad 404 can be in contact with the inner wall surface of the silk thread bobbin, so as to limit and fix the inner wall surface of the silk thread bobbin. Moreover, with the cooperation of the rotating shaft 403, the silk thread bobbin can be driven to rotate correspondingly during the process of embroidering and pulling the thread, ensuring that the silk thread can be smoothly pulled out. At the same time, the protective pad 404 made of soft rubber material can not only protect the inner wall surface of the silk thread bobbin, but also prevent the silk thread bobbin from sliding upward during rotation, ensuring the stability and firmness of the silk thread bobbin sleeved on the outer wall surfaces of the three protective pads 404.

[0028] As Figure 1 and Figure 2 shown, a plug-in cavity 8 communicating with its interior is formed at the top of the slide rail 3;

[0029] Specifically, by placing the mounting post 401 vertically above the plug-in cavity 8 and then moving the mounting post 401 downward, the purpose of installing the mounting post 401 in the inner cavity of the slide rail 3 can be achieved, and the structure is simple and easy to operate.

[0030] As Figure 2 shown, the telescopic part 7 includes a support plate 703. A support plate 703 is arranged on one side of the placing rod 2. A damping spring 701 and a telescopic rod 702 are connected between the side wall surface of the support plate 703 and the side wall surface of the mounting post 401;

[0031] Specifically, the provided damping spring 701 and telescopic rod 702 can enhance the stability of the mounting post 401 installed in the inner cavity of the slide rail 3, and at the same time can also enhance the smoothness of the mounting post 401 sliding in the inner cavity of the slide rail 3.

[0032] As Figure 2 and Figure 3As shown in the figure, the rotating part 5 includes a bracket 501. Three circumferentially distributed brackets 501 are installed at the top of the placing rod 2. A threaded sleeve 502 is installed on the adjacent side wall surfaces of the three brackets 501. A threaded column 503 is threadedly connected inside the threaded sleeve 502. The bottom of the threaded column 503 is connected to a chassis 505 through a bearing member. A connecting rod 506 is rotatably connected between the outer wall surface of the chassis 505 and the side wall surface of the mounting column 401;

[0033] To facilitate the rotation of the threaded column 503, a grip rod 504 is fixedly connected to the hand-held end of the threaded column 503;

[0034] Specifically, by holding the grip rod 504 by hand, the threaded column 503 can be driven to rotate. Under the pulling cooperation of the connecting rod 506, the mounting column 401 can be driven to move along the laying track of the slide rail 3, so that the three mounting columns 401 can be driven to gather or disperse from each other, so that the distance between the mounting columns 401 can be adjusted to a suitable size for fixing spools of different sizes.

[0035] When in use, the user can hold the grip rod 504 to drive the threaded column 503 to rotate. During the rotation of the threaded column 503, under the pulling action of the connecting rod 506, the mounting column 401 can be driven to slide inside the slide rail 3. Subsequently, the user can, according to the usage requirements, choose to install the support plate 703 on the side wall surface of the placing rod 2 or on the side wall surfaces of two adjacent brackets 501. When the mounting column 401 moves, the damping spring 701 and the telescopic rod 702 can correspondingly expand and contract, ensuring the smoothness and stability of the movement of the mounting column 401. Then, place the spool on the outside of the three protective pads 404. Finally, rotate the threaded column 503 in the reverse direction, which can drive the three mounting columns 401 to move away from each other, so that the distance between the three protective pads 404 can be adjusted to a suitable size for fixing the spool. When the outer wall surface of the protective pad 404 is in contact with the inner wall surface of the spool, stop rotating the threaded column 503. When embroidering and pulling the thread, under the rotation action of the rotating shaft 403, the spool can be driven to rotate along the outer wall surfaces of the three protective pads 404. The protective pad 404 with anti-slip lines on the outer wall surface and made of soft rubber material can increase the static friction coefficient with the spool, thereby reducing the possibility of the spool disengaging upward from the protective pad 404 and ensuring the stability and firmness of the spool during use.

[0036] In summary: Through the three circumferentially distributed limiting parts 4 provided, the inner wall surface of the spool can be limited and intercepted, preventing the spool from disengaging upward during rotation, ensuring the stability of the spool during use, effectively ensuring the normal development of the embroidering operation, and guaranteeing the subsequent embroidering quality; Through the rotating part 5 provided, the distance between the three limiting parts 4 can be changed to adapt to spools of different sizes, enhancing the practicability of the product.
