Description

Technical Field

[0001] This utility model relates to the field of circular knitting machines, and in particular to a circular knitting machine with automatic winding and cutting capabilities. Background Technology

[0002] Circular knitting machines, as the most core and widespread weft knitting production equipment in the modern knitting industry, have profoundly shaped the landscape of the global textile and apparel industry through their development and application. Their technological background is rooted in the urgent need for efficient, continuous, and large-scale production of high-quality tubular or wide-width knitted fabrics, especially in high-volume sectors such as long-yarn fabrics, skirts, and shirts, where cost, efficiency, and quality are critical.

[0003] In traditional circular knitting machines, most knitting processes involve winding yarn onto a feed post, placing the yarn, and then knitting it through the circular knitting machine. However, many knitted products require manual cutting during production, which increases production costs, manpower, and material consumption, leading to reduced work efficiency and lower product quality. To better address these issues, promote the development of industry technology, and enhance core competitiveness, this application proposes a new structural design that differs from existing technologies.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-4 A circular knitting machine with automatic winding and cutting capabilities includes a main body 1. Multiple fixed frames 9 are bolted to the outer side of the main body 1. A second ring 19 is bolted to the top of each fixed frame 9. Multiple support pillars 12 are welded to the top of the second ring 19. Stationary blades 13 are bolted to the outer side of each support pillar 12. Moving blades 10 are rotatably connected to the outer side of each support pillar 12 via bearings. A toothed ring 11 is rotatably connected to the outer side of the second ring 19. A fixed post 14, corresponding to each moving blade 10, is bolted to the top of the toothed ring 11, and the fixed post 14 is rotatably connected to the moving blade 10. The second ring 19 has a drive assembly on one side that rotates the toothed ring 11, and a wire feeding assembly on the outer side of the second ring 19 for feeding wire. In use, rotating the toothed ring 11 drives the fixed post 14 on the toothed ring 11 to rotate. At this time, since the fixed post 14 is rotatably connected to the moving blade 10, and the moving blade 10 rotates with the support post 12 as the rotation point, the moving blade 10 is driven to rotate through the toothed ring 11, so that the moving blade 10 intersects with the stationary blade 13, thereby cutting the wire material in the conductor coil 15 without manual cutting, reducing production costs, reducing the consumption of manpower and material resources, and increasing work efficiency and production quality. The drive assembly includes a second motor 20. An L-shaped mounting bracket 17 is bolted to the outside of the large circular knitting machine body 1. The second motor 20 is bolted to one side of the L-shaped mounting bracket 17. One end of the output shaft of the second motor 20 passes through the L-shaped mounting bracket 17 and is connected to a third gear 18 via a coupling key. The third gear 18 meshes with a gear ring 11. In use, the second motor 20 is started, which drives the third gear 18 to rotate. Since the third gear 18 meshes with the gear ring 11, when the third gear 18 rotates, the gear ring 11 rotates. The wire feeding assembly includes multiple wire feeding posts 6. Multiple L-shaped support frames 3 are fixed to the outside of the second ring 19 by bolts. The top of the multiple L-shaped support frames 3 is fixed to the first ring 4 by bolts. The multiple wire feeding posts 6 are rotatably connected to the first ring 4. The bottom of the first ring 4 is provided with a linkage assembly that makes the multiple wire feeding posts 6 rotate. In use, the wire is wound around the outside of the wire feeding posts 6, and the wire feeding posts 6 feed the large circular knitting machine, which improves the efficiency and ease of operation of the large circular knitting machine. In this utility model, the linkage component includes multiple first gears 2, and multiple feed posts 6 are all welded to the bottom of a rotating shaft 7, which passes through an L-shaped support frame 3. Multiple first gears 2 are keyed to the outside of the rotating shaft 7. A second gear 8 is rotatably connected to the outside of the large circular knitting machine body 1, and the second gear 8 meshes with the first gear 2. The outside of the large circular knitting machine body 1 is provided with a power component that drives one of the first gears 2 to rotate. In use, it drives one of the first gears 2 to rotate, and the first gear 2 meshes with the second gear 8. At this time, it drives the second gear 8 to rotate, and the rotation of the second gear 8 drives the remaining first gears 2 to rotate. Since the top of the first gear 2 is keyed to the rotating shaft 7, and the top of the rotating shaft 7 is fixed with the feed post 6, the first gear 2 drives the rotating shaft 7 to rotate, causing the feed post 6 to rotate, thereby winding up the wire. Thus, by controlling the first motor 16, the wire is automatically cut, increasing the convenience of the device. In particular, the power assembly includes a first motor 16. A fixing plate is bolted to the outside of the large circular knitting machine body 1. The first motor 16 is bolted to the bottom of the fixing plate. One end of the output shaft of the first motor 16 passes through the fixing plate and is connected to one of the rotating shafts 7 via a coupling. In use, the first motor 16 is started, which drives one of the first gears 2 to rotate. The rotation of the first gear 2 serves as the power source. The top of the second ring 19 is bolted with a guide coil 15 corresponding to the wire feeding post 6. The tops of the multiple wire feeding posts 6 are threaded with end caps 5, which allow the wire to pass through the guide coils 15 into the large circular knitting machine during use, preventing the wire from shifting or tangling during use and increasing the stability of the device.

[0017] Working principle: When it is necessary to wind up the wire, the first motor 16 is started, which drives one of the first gears 2 to rotate. The first gear 2 meshes with the second gear 8. At this time, the rotation of one of the first gears 2 serves as a power source, driving the second gear 8 to rotate. The rotation of the second gear 8 drives the remaining first gears 2 to rotate. Since the top of the first gear 2 is keyed to the rotating shaft 7, and the top of the rotating shaft 7 is fixed with the wire feeding post 6, the first gear 2 drives the rotating shaft 7 to rotate, causing the wire feeding post 6 to rotate, thereby winding up the wire. Thus, by controlling the first motor 16, the wire can be automatically cut, increasing the convenience of the device.

[0018] When it is necessary to cut the wound wire, the second motor 20 is started, which drives the third gear 18 to rotate. Since the third gear 18 meshes with the gear ring 11, when the third gear 18 rotates, the gear ring 11 rotates, which in turn drives the fixed column 14 on the gear ring 11 to rotate. At this time, since the fixed column 14 is rotatably connected to the moving blade 10, and the moving blade 10 rotates with the support column 12 as the rotation point, the moving blade 10 is driven to rotate through the gear ring 11, so that the moving blade 10 intersects with the stationary blade 13, thereby cutting the wire in the guide coil 15 without manual cutting, reducing production costs, reducing the consumption of manpower and material resources, and increasing work efficiency and production quality.

[0019] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
