Description

Technical Field

[0001] This technical solution relates to the field of sewing machine winding equipment technology, and specifically refers to a winding device. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, allowing one or more layers of fabric to be interwoven or sewn together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. Sewing is fast and easy to use. This has led to the development of art forms such as hand-pressed embroidery and computerized embroidery.

[0003] When a sewing machine is working, it needs to sew the sewing thread, bobbin thread, and top thread together. The bobbin thread is manually wound onto the bobbin thread reel inside the rotary hook. In order to improve the bobbin thread winding efficiency, Chinese patent CN110938946B discloses a fully automatic rotary hook bobbin thread winding machine without a bobbin core. This winding machine winds the thread through a winding shaft transmission assembly and also uses a winding gear combination to achieve simultaneous winding of multiple rotary hooks. However, this winding machine has a complex structure and a large size. Summary of the Invention

[0004] The purpose of this technical solution is to provide a winding device that can drive multiple winding mechanisms to wind simultaneously through a drive shaft of the drive unit, thereby solving the problem of low processing efficiency of the original winding machine.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A winding device includes: a frame; a drive unit disposed within the frame, including a drive shaft and a plurality of drive wheels sleeved on the drive shaft; and a winding device disposed on the frame, including a plurality of winding mechanisms; wherein each drive wheel drives one winding mechanism; when the drive shaft rotates, all the winding mechanisms perform winding operations.

[0007] Preferably, the drive wheel has grooves.

[0008] Preferably, the winding mechanism includes: a winding base, disposed on the frame and having a through hole; a winding rod, movably disposed within the through hole and having a mounting position at its upper end for mounting a bottom thread spool; and an abutting wheel, disposed at the lower end of the winding rod and movably abutting against a corresponding drive wheel; wherein the upper end of the winding rod has a locking portion, and the winding rod is mounted from top to bottom on the through hole of the winding base through the locking portion.

[0009] Preferably, the upper end of the winding rod has a mounting part one and a mounting part two, with a gap between the mounting part one and the mounting part two; when the mounting part one and the mounting part two sway in the direction of the gap, the bottom thread reel can be installed on the winding rod.

[0010] Preferably, the winding mechanism further includes: a lead seat, disposed on the frame and having a lead port; a guide seat, having a guide port; and a cutter, disposed on the frame; wherein the sewing thread enters through the lead port, then passes through the guide port and is wound onto the bobbin, and after winding is completed, the sewing thread is cut by the cutter.

[0011] Preferably, the winding mechanism further includes a pressure handle hinged to the winding seat; moving the pressure handle can bring the abutment wheel closer to or away from the drive wheel.

[0012] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0013] 1. The winding equipment designed in this technical solution includes a drive device and multiple winding mechanisms. The drive device has a drive shaft with several drive wheels on it. Each drive wheel can drive the corresponding winding mechanism to wind wire, which increases the winding efficiency. At the same time, the entire winding equipment has fewer components and a smaller size, and the processing task can be completed with only the drive device and the winding device.

[0020] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, a winding device includes a frame 1, a drive unit 2, and a winding device 5. The drive unit 2 and the winding device 5 are mounted on the frame 1. The drive unit 2 includes a drive component, a drive shaft 3, and drive wheels 4. The drive component can be any power source that can rotate the drive shaft 3. In this embodiment, it is configured as a motor. The drive shaft 3 is located at the output end of the motor. The drive wheels 4 are evenly spaced along the axial direction of the drive shaft 3 and can rotate with the drive shaft 3. The winding device 5 includes a plurality of winding mechanisms 6, the number of which corresponds to the number of drive wheels 4. The abutment wheel 9 of each winding mechanism 6 is driven by the corresponding drive wheel 4. In this way, when the drive shaft 3 rotates, it can drive all the winding mechanisms 6 to wind wire, thereby improving the winding efficiency.

[0022] Furthermore, the winding device 5 also includes several thread guides 14, guide seats 16, and thread cutters 18. Each winding mechanism 6 is provided with a set of thread guides 14, guide seats 16, and thread cutters 18 on its side. The thread guide 14 has a thread inlet 15, and the guide seat 16 has a guide outlet 17. After the sewing thread is wound around the thread guide 14 once, it extends out through the thread inlet 15 and then passes through the guide outlet 17 on the guide seat 16 before being wound onto the bobbin spool 20. After the winding is completed, the sewing thread is cut by the thread cutter 18. The guide seat 16 can adjust the thread entry angle so that the sewing thread can be wound more smoothly.

[0023] like Figure 2 As shown, in order to increase the friction between the drive wheel 4 and the abutment wheel 9, a groove 11 is added to the drive wheel 4. The groove 11 can be understood as a partial recess, which makes it easier for the drive wheel 4 to drive the abutment wheel 9 to rotate. At the same time, the drive wheel 4 is fixed to the drive shaft 3 by screws, so the pressure between the drive wheel 4 and the abutment wheel 9 can be adjusted by adjusting the installation position of the drive wheel 4 on the drive shaft 3, thereby adjusting the friction between the two.

[0024] Chinese patent CN220149810U discloses a thread winder for a sewing machine. The working principle of the thread winding mechanism 6 in this application can be found in the aforementioned document. Specifically, as follows... Figure 4 and Figure 5As shown, the winding mechanism 6 includes a winding seat 7, a winding rod 8, a pressing handle 19, and an abutment wheel 9. The winding seat 7 is detachably mounted on the frame 1 by screws. The winding rod 8 passes through a through hole in the winding seat 7, the inner diameter of which is larger than the outer diameter of the winding rod 8, allowing the winding rod 8 to move within the through hole. The winding rod 8 has a locking part 10 with an outer diameter larger than the through hole, allowing the winding rod 8 to be mounted on the winding seat 7 without falling off. The abutment wheel 9 is located at the lower end of the winding rod 8. The pressing handle 19 is hinged to the winding seat 7. By moving the pressing handle 19... 9 allows the winding rod 8 to move within the through hole, causing the abutting wheel 9 to move closer to or further away from the drive wheel 4. When the pressing handle 19 is moved to the receiving cavity 21 within the bobbin thread 20, the abutting wheel 9 abuts against the drive wheel 4, and winding begins. As the sewing thread in the bobbin thread 20 winds, the sewing thread pushes the pressing handle 19 outward until the pressing handle 19 disengages from the receiving cavity 21. At this point, the abutting wheel 9 disengages from the drive wheel 4, and winding stops. The specific principle of the pressing handle 19 driving the winding rod 8 to move can be found in the aforementioned literature and will not be elaborated upon here.

[0025] Furthermore, the upper end of the winding rod 8 has a mounting position for mounting the bottom thread plate 20. The upper part of the winding rod 8 is composed of a swingable mounting part 12 and a mounting part 23. There is a gap between the mounting part 12 and the mounting part 23. When the mounting part 12 and the mounting part 23 swing in the direction of the gap, the outer diameter of the mounting position formed by the two decreases, so the bottom thread plate 20 can be mounted on the winding rod 8.
