Description
Technical Field
[0001] This utility model relates to the technical field of sewing template machine accessories, and in particular to a template machine thread sweeping device. Background Technology
[0002] The thread sweeping device on a sewing machine is one of the core auxiliary components, its importance directly impacting sewing quality, machine lifespan, production efficiency, and fabric protection, especially crucial for home sewing and mass garment production. During sewing, short threads and lint easily remain on the fabric surface. If not cleaned promptly, this can lead to "rough edges" and "exposed threads" on the finished product. This is particularly problematic for delicate fabrics (silk, chiffon), light-colored fabrics, or high-end custom garments, where thread defects directly lower the product's quality and may even necessitate rework. Installing a thread sweeping device on the sewing machine head immediately removes lint after sewing, ensuring smooth and even stitches and a clean, flat fabric surface.
[0003] Existing sewing machine thread sweeping devices suffer from several drawbacks. The sweeping rod deforms due to the force of the thread during the sweeping process, affecting its rigidity and durability. This makes the sweeping rod unstable during sweeping. Furthermore, most current sweeping rods have a single sweeping direction and cannot be extended to sweep in different directions on the template machine. In addition, the sweeping device is limited by installation space and cannot be adapted to the compact template machine. Complex sweeping devices also lead to inconvenient maintenance. Utility Model Content

An L-shaped hook is provided at the end of the sweeping rod away from the sweeping shaft, and a bending section is provided at the end of the sweeping rod near the L-shaped hook.
[0005] Furthermore, the sweeping shaft fixing seat has a gate-shaped structure, with a first mounting hole at the top center of the sweeping shaft fixing seat for mounting on the template machine head, and second mounting holes on the two side support parts respectively.
[0006] Furthermore, the central axes of the second mounting holes on both sides of the sweeping shaft fixing seat are on the same straight line, and the sweeping shaft is installed in the second mounting holes on both sides of the sweeping shaft fixing seat.
[0007] Furthermore, one end of the sweeping shaft is provided with a curved plate, and a connecting rod is provided on the side wall of the curved plate. The sweeping shaft is connected to the sweeping shaft push plate through the connecting rod. The other end of the sweeping shaft is provided with a first through hole on its side perpendicular to its axis, and the sweeping rod is threadedly fastened to the through hole of the sweeping rod.
[0008] Furthermore, the sweeping shaft push plate has a waist hole at one end near the sweeping shaft, and the connecting rod passes through the waist hole. The sweeping shaft push plate has a second through hole at one end near the sweeping driver, and the telescopic working end of the sweeping driver extends into the through hole.
[0009] Furthermore, the sweeping shaft push plate has a Z-shaped bending structure.
[0010] Furthermore, the side wall of the sweeping driver is provided with a pneumatic connector and a throttle valve, the throttle valve is located below the pneumatic connector, and the top surface and side wall of the sweeping driver are also provided with a third mounting hole.
[0011] Furthermore, the threaded ring for sweeping the wire is provided with a through hole, the third through hole is provided at one end of the sweeping shaft near the sweeping rod, and the side of the threaded ring for sweeping the wire is provided with a radial hole perpendicular to the central axis, and the threaded fastener is installed in the radial hole.
[0012] The outstanding and beneficial technical effects of this utility model compared to the prior art are: The sweeping rod of this sweeping device is driven by a cylinder to swing back and forth, pulling the thread end out of the needle eye and sweeping the thread end of the opposite thread, improving sweeping efficiency and stability. In addition, the sweeping rod is provided with a bending section to improve its durability and also allows the sweeping rod to extend to different directions of the template machine head to sweep the thread end at different positions.

Detailed Implementation
[0018] 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.
[0019] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] This utility model proposes a template machine line-sweeping device, which is installed on the template machine head, as shown in the attached figure. Figure 1 As shown, the template machine sweeping device includes a sweeping shaft fixing seat 1 on the template machine head, a sweeping shaft 2 on the sweeping shaft fixing seat 1, a sweeping rod 3 on one end of the sweeping shaft 2, and a sweeping driver 4 on the other end of the sweeping shaft 2. A sweeping shaft push plate 6 is provided between the sweeping shaft 2 and the sweeping driver 4, and a sweeping threaded tightening ring 5 is provided between the sweeping shaft 2 and the sweeping rod 3.
[0021] As attached Figure 3 As shown, the end of the sweeping rod 3 furthest from the sweeping shaft 2 is provided with an L-shaped hook 31. The L-shaped hook 31 is used to pull the thread end out of the needle eye, preventing the thread end from becoming too long and forming a bird's nest, thus affecting the aesthetics and quality of the sewing. Furthermore, the end of the sweeping rod 3 near the L-shaped hook 31 is provided with a bent section 32. The bent section 32 connects the long straight section of the sweeping rod 3 and the L-shaped hook 31, changing the extension direction of the L-shaped hook 31 to adapt to the internal spatial layout of the template machine, avoiding spatial interference, optimizing the overall space utilization efficiency of the template machine, and making the template machine's structure compact. In addition, the bent section 32 on the sweeping rod 3 allows the force transmitted by the long straight section of the sweeping rod 3 to be output at different angles, thereby changing the direction of force transmission and enabling the sweeping rod to sweep the thread in different directions. Furthermore, the bending section 32 provided in the sweeping rod 3 can improve the stability and durability of the overall structure of the sweeping rod 3 and prevent the sweeping rod 3 from deforming when the sweeping is subjected to excessive resistance.
[0022] As attached Figure 2 As shown, the sweeping shaft fixing seat 1 has a U-shaped structure. The top center of the sweeping shaft fixing seat 1 has a first mounting hole 11 for mounting on the template machine head. Preferably, there are two first mounting holes 1, which can more evenly distribute the external load. The first mounting holes 1 are evenly distributed at the top center of the sweeping shaft fixing seat 1. The sweeping device is mounted on the template machine head by bolt fastening, ensuring the stability of the sweeping device's installation position. Further, the two side support portions of the sweeping shaft fixing seat 1 each have a second mounting hole 12. The central axes of the second mounting holes 12 on both sides of the sweeping shaft fixing seat 1 are on the same straight line. The sweeping shaft 2 passes through the second mounting holes 12 on both sides of the sweeping shaft fixing seat 1. Driven by the sweeping driver 4, the sweeping shaft 2 rotates within the sweeping shaft fixing seat 1, causing the sweeping rod 3 to swing back and forth, thereby achieving the sweeping of the line by the sweeping rod 3.
[0023] As attached Figure 2 As shown, one end of the sweeping shaft 2 is provided with a curved plate 21, wherein the curved plate 21 restricts the axial movement of the sweeping shaft 2 and prevents the sweeping shaft 2 from detaching from the sweeping shaft fixing seat 1. Further, a connecting rod 22 is provided on the side wall of the curved plate 21, and the sweeping shaft 2 is connected to the sweeping shaft push plate 6 through the connecting rod 22. The other end of the sweeping shaft 2 has a first through hole 23 on its side perpendicular to its axis. One end of the long straight section of the sweeping rod 3 is threadedly fastened into the through hole 23 of the sweeping rod 3, thereby realizing the fixed connection between the sweeping rod 3 and the sweeping shaft 2.
[0024] As attached Figure 4 As shown, further, the sweeping shaft push plate 6 has a waist hole 61 at one end near the sweeping shaft 2. Preferably, the waist hole 61 consists of a central rectangular hole and two semi-circular holes at both ends, and the connecting rod 22 passes through the waist hole 61. Further, the sweeping shaft push plate 6 has a second through hole 62 at one end near the sweeping driver 4. The telescopic working end of the sweeping driver 4 extends into the through hole 62, and the sweeping driver 4 drives the sweeping shaft push plate 6 to rotate, thereby causing the sweeping rod 3 to swing back and forth to perform the sweeping action. Further, a fixing nut is provided on the top and bottom surfaces of the through hole 62 to secure the telescopic working end of the sweeping driver 4, preventing the telescopic working end of the sweeping driver 4 from loosening and improving the connection reliability between the sweeping driver 4 and the sweeping shaft push plate 6.
[0025] Preferably, the sweeping shaft push plate 6 has a Z-shaped bending structure. The special Z-shaped bending structure can meet the compact space adaptation requirements of the template machine. In addition, the Z-shaped bending structure has stronger resistance to deformation, thereby improving the stability and durability of the sweeping shaft push plate 6.
[0026] As attached Figure 2 As shown, the sweeping driver 4 is a cylinder. A pneumatic connector 41 and a throttle valve 42 are provided on one side wall of the sweeping driver 4. The throttle valve 42 is located below the pneumatic connector 41. A third mounting hole 43 is also provided on the top surface and side wall of the sweeping driver 4. The pneumatic connector 41 connects to an air pipe to deliver compressed air. The throttle valve 42 has a knob to adjust the airflow rate, thereby precisely controlling the movement speed of the cylinder, ensuring stable and uniform rotation of the sweeping shaft 2, which in turn drives the sweeping rod 3 to swing evenly, achieving smooth sweeping of the wire by the sweeping rod 3.
[0027] Furthermore, the threaded ring 5 for sweeping is provided with a through hole 51. The third through hole 51 is located at one end of the sweeping shaft 2 near the sweeping rod 3. The side of the threaded ring 5 for sweeping is provided with a radial hole 52 perpendicular to the central axis. The radial hole 52 is a hole machined in the threaded ring 5 along the radial direction, and its axis is perpendicular to the axis of the threaded ring 5 for sweeping. The threaded fastener is installed in the radial hole 52. The threaded ring 5 for sweeping restricts the displacement of the sweeping shaft 2 and ensures the stability of the rotation of the sweeping shaft 2, thereby enabling the sweeping rod 3 to swing smoothly to perform the sweeping action.
[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
