Description

Technical Field

[0001] This invention relates to the field of double-sided circular knitting machines, specifically to a high-efficiency, low-noise composite transmission structure for double-sided circular knitting machines. Background Technology

[0002] In the textile and knitting industry, the double-sided circular knitting machine is the core equipment for producing double-sided fabrics (such as rib fabric, cotton jersey fabric, etc.). The stability of its transmission structure, transmission efficiency and operating noise directly determine the fabric production quality, equipment energy consumption and workshop working environment. Only when the transmission system has high rigidity, low friction, good centering and rigid transmission relationship can the neatness of the fabric edge, the symmetry of the pattern and the uniformity of knitting be maintained at a stable level, thereby reducing the defect rate and rework costs.

[0003] Traditional knitting machines typically use independent drive systems for the cylinder drive, needle plate drive, and winding drive. The power source and transmission components are distributed in different positions on the machine, resulting in problems such as high power loss and poor synchronization. The cylinder drive transmits power through multiple sets of intermediate gears or drive shafts. At the same time, the cylinder and needle plate need to be strictly synchronized and are affected by the fluctuations of their respective motors and the wear of gears, which easily leads to defects such as misaligned needles, missed needles, and skewed fabric. To address these issues, we propose a high-efficiency and low-noise composite transmission structure for double-sided circular knitting machines. Summary of the Invention

[0030] Working Principle: The frame base 2 serves as the load-bearing and stable foundation for the entire equipment. Its top surface is firmly fixed to the bottom surface of the hollow structure machine base 1. Simultaneously, a soundproof enclosure 3 (6) is fixedly connected to the side of the machine base 1. The side of soundproof enclosure 3 (6) facing the frame base 2 is fixed to soundproof enclosure 1 (4). A soundproof enclosure 2 (5) is also installed on the side of the frame base 2 facing the machine base 1, and the outer side of soundproof enclosure 2 (5) is tightly connected to soundproof enclosure 1 (4). These three soundproof enclosures together form a closed space, enclosing the core transmission components. When the equipment starts and enters the working state, the syringe transmission component is first activated to drive the syringe 7 to rotate. The motor 2 (16), fixed to the internal partition 29 of soundproof enclosure 1 (4), begins to operate. Its output shaft is rigidly connected to the transmission shaft 2 (17) via a high-precision coupling. The transmission shaft 17 is connected at one end to the output shaft of the motor 16, and at the other end extends through and into the soundproof enclosure 6. It is rotatably connected to the partition 29 and the inner wall of the soundproof enclosure 6 away from the soundproof enclosure 4 via bearings. As the motor 16 operates, the transmission shaft 17 rotates synchronously, driving the gear 19 fixed at its end to rotate. Since the gear 19 passes through the square hole 31 on the side of the machine tool 1 and precisely meshes with the gear 20 inside the machine tool 1, the rotation of the gear 19 directly drives the gear 20 to rotate synchronously. Simultaneously, multiple evenly distributed circumferentially distributed limiting rods 21 are fixed to the side of the gear 20 facing the syringe 7. These limiting rods 21 are precisely inserted into the annular protrusion 2 at the bottom of the syringe 7. Within the limiting groove 27 of 2, the rotation of gear 20 directly drives the syringe 7 to rotate smoothly at the same speed. Simultaneously with the rotation of the syringe 7, the needle disc transmission assembly starts synchronously, ensuring high-precision synchronous rotation between the needle disc 8 and the syringe 7. First, the linkage between the needle disc 8 and the syringe 7 is achieved through the mounting ring 23. The mounting ring 23 is inserted into the inner wall of the syringe 7, and its inner annular surface has multiple evenly distributed circumferential fixing holes 25. Operators can pass screws through the fixing holes 25 to firmly fix the mounting ring 23 inside the syringe 7, allowing the mounting ring 23 to rotate synchronously with the syringe 7. Subsequently, the annular protrusion 26 integrally formed at the bottom of the needle disc 8 is inserted into the inner space of the syringe 7 on the side facing away from the machine frame base 2, and the needle disc 8 is connected to the annular protrusion 26. One side of the annular protrusion 26 is in close contact with the top surface of the syringe 7, ensuring that the axial position of the needle disc 8 and the syringe 7 are aligned. Simultaneously, the side of the annular protrusion 26 facing away from the needle disc 8 has multiple limiting grooves 28 that correspond exactly to the number and position of the limiting rods 24 on the top surface of the mounting ring 23. The limiting rods 24 are inserted one-to-one into the limiting grooves 28. When the syringe 7 drives the mounting ring 23 to rotate, the mounting ring 23, through the cooperation of the limiting rods 24 and the limiting grooves 28, directly drives the annular protrusion 26 and the needle disc 8 to rotate synchronously. Since the power source for the needle disc 8 is the already stably rotating syringe 7, it ensures that the rotational speeds of the needle disc 8 and the syringe 7 are completely consistent. After the syringe 7 and the needle disc 8 work together to complete the double-sided fabric weaving, the winding transmission assembly is activated to stably wind up the finished fabric.The fabric roll receiving frame 3 is located between the machine base 2 and the machine platform 1. A rotating shaft 14, fixedly connected to the center of its bottom surface, passes through the second soundproof enclosure 5 and is rotatably connected to the second soundproof enclosure 5 via a bearing. The winding power comes from a motor 9, also fixed on the partition 29. After the motor 9 starts, its output shaft drives the transmission shaft 10 to rotate via a coupling. The other end of the transmission shaft 10 is rotatably connected to the inner wall of the first soundproof enclosure 4 away from the third soundproof enclosure 6 via a bearing, ensuring smooth transmission. A synchronous pulley 11 is fixedly sleeved on the cylindrical surface of the transmission shaft 10, and a synchronous belt 12 is sleeved on the synchronous pulley 11. The other end of the synchronous belt 12... The side of the belt passes through a square hole 30 on the connecting surface between the soundproof enclosure 1 (4) and the soundproof enclosure 2 (5), and engages with a synchronous pulley 13 fixed on the rotating shaft 14 inside the soundproof enclosure 2 (5). When the drive shaft 10 drives the synchronous pulley 11 to rotate, the synchronous belt 12 stably transmits power to the synchronous pulley 13. The synchronous pulley 13 then drives the rotating shaft 14 and the fabric roll receiving frame 3 to rotate synchronously, thereby winding the finished fabric woven from the cylinder 7 and needle plate 8 and fed downwards into a fabric roll at a uniform speed and tightness. The operator can adjust the speed of the motor 9 to precisely match the winding speed of the fabric roll receiving frame 3 with the weaving speed of the cylinder 7.
