Detailed Implementation

[0020] 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.

[0021] Example: An automatic sewing thread winding device, such as Figures 1-4 As shown, the system includes a mounting frame 1, a rotating rod 2, a winding drum 21, a first motor 3, a fixed frame 4, a bidirectional lead screw 5, a movable frame 7, a second motor 8, and a baffle 9. A vertical frame 101 is mounted on the top left front side of the mounting frame 1. The first motor 3 is mounted longitudinally and parallel to the top of the vertical frame 101. The rotating rod 2 is connected to the output shaft of the first motor 3. A rotating wheel 22 is mounted on the rotating rod 2. When the first motor 3 is not in operation, the rotating rod 2 is driven to rotate by manually rotating the rotating wheel 22. The rotating rod 2 rotates through the mounting frame 1 and is detachably connected to the winding drum 21. A baffle 9 is rotatably mounted on the mounting frame 1. The maximum rotation angle of the baffle 9 on the mounting frame 1 is 90 degrees. A handle 10 is rotatably mounted on the mounting frame 1. The handle 10 is fixed to the baffle 9 and is used to drive the baffle 9 to rotate so that it can be connected to or separated from the rotating rod 2. When the rotating rods 2 are vertically connected, the baffle 9 limits the winding drum 21 on the rotating rods 2. The top rear side of the mounting frame 1 is symmetrically provided with fixed frames 4. The fixed frames 4 are parallel to the vertical frame 101. The two fixed frames 4 are rotatably arranged vertically and horizontally between them. The two fixed frames 5 are threadedly connected to the movable frame 7. The fixed frame 4 is provided with a guide frame 51 to guide the horizontal movement of the movable frame 7. The crossbar on the guide frame 51 is slidably engaged with the movable frame 7. The end of at least one two-way screw 5 is connected to the output shaft of the second motor 8 installed on the fixed frame 4. A pulley group 6 is provided between the upper and lower two-way screws 5. The pulley group 6 includes a pulley installed at the end of the two-way screw 5 and a flat belt between the upper and lower pulleys. The upper and lower two-way screws 5 transmit power through the pulley group 6 to achieve the effect of synchronous rotation of the upper and lower two-way screws 5.

[0022] like Figure 3 As shown, a threaded rod 12 is threadedly connected to the middle of the vertical frame 101. The threaded rod 12 passes through the end of the vertical frame 101 and is rotatably connected to a limiting plate 11. The rotating rod 2 slides through the limiting plate 11. The winding drum 21 contacts and engages with the limiting plate 11. The threaded rod 12 drives the limiting plate 11 to move horizontally along the rotating rod 2, thereby adjusting the distance between the limiting plate 11 and the baffle 9 according to the length of the winding drum 21.

[0023] like Figure 4 andFigure 5 As shown, a fixed rod 15 is arranged horizontally side by side on the movable frame 7. A connecting rod 151 is rotatably connected to the fixed rod 15. A roller 16 is installed at the lower end of the connecting rod 151. A torsion spring 17 is provided between the ends of the connecting rod 151 and the fixed rod 15. The two ends of the torsion spring 17 are connected to the fixed rod 15 and the connecting rod 151 respectively. Under normal conditions, the two rollers 16 are in contact with each other, and the sewing thread passes through the gap between the two rollers 16. The gap between the two rollers 16 can be flexibly adjusted according to the thickness of the sewing thread through the cooperation between the torsion spring 17 and the connecting rod 151.

[0024] In use, firstly, the bobbin 21 is installed on the rotating rod 2, and the baffle 9 is rotated 90 degrees towards the rotating rod 2, so that the baffle 9 is in movable contact with the rotating rod 2. Then, the first motor 3 is energized, and its output shaft drives the rotating rod 2 to rotate. The rotation of the rotating rod 2 directly drives the bobbin 21 connected to it to rotate, thus evenly winding the sewing thread onto the bobbin 21. Next, the second motor 8 is energized, and its output shaft drives the bidirectional lead screw 5 connected to it to rotate. The rotation of the bidirectional lead screw 5 drives the moving frame 7 to reciprocate horizontally along the guide frame 51. Since the sewing thread connects to the bobbin 21 after being wound around the moving frame 7, as the thread... The horizontal movement of the movable frame 7 causes the sewing thread to move left and right along the winding drum 21, thereby winding it evenly layer by layer onto the drum, ensuring that the sewing thread is wound smoothly and efficiently onto the winding drum 21. The cooperation between the limiting plate 11 and the baffle 9 ensures the stability of the winding drum 21 during the winding operation and prevents its displacement. After the winding operation is completed, the first motor 3 is turned off, and the baffle 9 is driven to rotate 90 degrees away from the rotating rod 2 by the handle 10, thereby separating the baffle 9 from the rotating rod 2, releasing the limitation on the winding drum 21, and thus conveniently removing the winding drum 21 from the rotating rod 2, thereby realizing the convenient installation and removal of the winding drum 21.

[0025] like Figure 2 As shown, the top of the mounting bracket 1 is provided with a guide rail 13, and a collection frame 14 is slidably connected to the guide rail 13. The guide rail 13 is an electric slide rail, and the collection frame 14 is used to collect the debris scraped off by the roller 16.

[0026] During the winding process, if there is lubricating grease or thread ends on the sewing thread, it will be scraped off as it passes through the roller 16 and fall into the collection box 14 that is slidably connected to the guide rail 13 below, so as to facilitate cleaning and maintenance.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
