[0001] This utility model relates to the field of textile machinery technology, specifically a yarn winding device. Background Technology

[0002] Yarn is a textile product made from various textile fibers processed to a certain fineness. It is commonly used in weaving, rope making, thread making, knitting, and embroidery, and is divided into staple fiber yarn and continuous filament yarn. After being made, yarn needs to be wound and packaged to facilitate subsequent processing, storage, and transportation.

[0003] Currently, yarn is typically wound using a winding device, which includes a frame on which a yarn bobbin is rotatably connected. The yarn bobbin usually consists of a cylindrical inner tube and a circular side plate. The inner tube winds the yarn, while the side plate provides fixation and support. After the yarn is wound, the yarn bobbin needs to be removed from the frame. However, because the yarn bobbin is fixed to the frame by clamps, these clamps are prone to wear and deformation after prolonged use, leading to jamming and making yarn bobbin removal difficult, time-consuming, and labor-intensive.

[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] Please see Figure 1-3As shown, a yarn winding device includes a frame on which a yarn bobbin 1 is mounted. The yarn bobbin 1 is made of stainless steel, which has high strength and hardness, is not easily corroded, and has good durability. The frame includes two supports 2, and a connecting mechanism is provided on the supports 2. The yarn bobbin 1 is rotatably connected between the supports 2 through the connecting mechanism. The connecting mechanism includes a first connecting seat 3 and a second connecting seat 4, which are connected by a connecting frame. A rotating shaft 5 is provided at both ends of the yarn bobbin 1 for insertion between the first connecting seat 3 and the second connecting seat 4. Several guide bearings are provided inside the first connecting seat 3 and the second connecting seat 4 for contacting the sidewalls of the rotating shaft 5. Therefore, when installing the yarn bobbin 1 onto the frame, the yarn bobbin 1 can be placed on the two supports first. Between the frame 2, the rotating shaft 5 is inserted into the second connecting seat 4. Then, the first connecting seat 3 is placed on the second connecting seat 4, and the first connecting seat 3 and the second connecting seat 4 are connected to each other by the connecting frame. Thus, the rotating shaft 5 is placed between the first connecting seat 3 and the second connecting seat 4, and is limited by the contact of the guide bearing. When the yarn bobbin 1 is rotated to wind up the yarn, the rotating shaft 5 will rotate inside the first connecting seat 3 and the second connecting seat 4, thereby driving the guide bearing to rotate as well. This ensures the smooth rotation of the yarn bobbin 1 and the smoothness of the yarn winding. When it is necessary to disassemble the yarn bobbin 1, simply remove the connecting frame first, and then remove the first connecting seat 3 from the second connecting seat 4 to release the limitation on the rotating shaft 5, so that the yarn bobbin 1 can be directly disassembled. The operation is relatively convenient and simple, saving time and effort. The guide bearing includes an inner ring 6 and an outer ring 7. A retainer 8 is provided between the inner ring 6 and the outer ring 7, and several rollers 9 are rotatably connected to the retainer 8. A support rod 10 is fixedly connected inside the first connecting seat 3 and the second connecting seat 4, and the inner ring 6 is fixedly connected to the support rod 10. When the yarn bobbin 1 is rotated, the rotating shaft 5 will pull the outer ring 7, thereby causing the rollers 9 to form rolling contact between the outer ring 7 and the inner ring 6, converting sliding friction into rolling friction. This can both support the rotating shaft 5 and reduce the friction between the rotating shaft 5 and the first connecting seat 3 or the second connecting seat 4, thus making the rotation of the rotating shaft 5 smoother. The connecting frame includes a frame body 11, and screws are threadedly connected to both sides of the frame body 11. Bolt 12 is provided, and threaded holes matching bolt 12 are provided on both sides of the first connecting seat 3 and the second connecting seat 4. When the first connecting seat 3 is placed on the second connecting seat 4, the frame 11 can be snapped into the first connecting seat 3 and the second connecting seat 4, thereby achieving a pre-connection of the first connecting seat 3 and the second connecting seat 4. Then, bolt 12 is screwed into the threaded hole, and the connection between the frame 11 and the first connecting seat 3 and the second connecting seat 4 is achieved through the threaded connection between bolt 12 and the threaded hole, thus achieving a firm combination between the first connecting seat 3 and the second connecting seat 4. When it is necessary to separate the first connecting seat 3 and the second connecting seat 4, simply unscrew bolt 12 from the threaded hole, and then remove the frame 11 to separate the first connecting seat 3 and the second connecting seat 4.The operation is relatively convenient and simple.

[0022] Please see Figure 4-6 As shown, a handle is detachably connected to one end of the rotating shaft 5. Force can be applied by gripping the handle, thereby rotating the rotating shaft 5 and subsequently rotating the yarn bobbin 1 to wind the yarn. This operation is convenient, and using the handle as the point of force makes operation easy and effortless. The handle includes a rotating rod 13, with several gripping rods 14 at one end and insertion rods 15 at the other end. Both ends of the rotating shaft 5 have insertion holes for inserting the insertion rods 15. 16. Several slots 17 are provided on the inner side wall of the insertion hole 16. The insertion rod 15 is provided with a locking block 18 for locking into the slot 17. When the handle is installed on the rotating shaft 5, the insertion rod 15 can be inserted into the insertion hole 16, so that the locking block 18 is locked into the slot 17. By limiting the locking block 18 through the slot 17, the connection between the insertion rod 15 and the insertion hole 16 can be realized. The rotating shaft 5 can be rotated by holding the rotating rod 13 and turning it. The operation is relatively convenient.
