Description

Technical Field

[0001] This utility model relates to the field of yarn feeding technology for knitting machines, and in particular to a yarn feeding device for a cylindrical knitting machine. Background Technology

[0002] The circular knitting machine, also known as a circular knitting machine, was invented in the mid-19th century. This machine can produce continuous tubular knitted fabrics and is suitable for producing clothing such as socks, underwear, and T-shirts. In the circular knitting machine, the yarn feeding device is responsible for accurately feeding the yarn into the knitting area in order to form a knit structure. As the speed of the knitting machine increases and the complexity of the fabric increases, the design and function of the yarn feeding device have become increasingly important.

[0003] When using the yarn feeding device of a circular knitting machine, the yarn bobbin needs to be installed at the yarn feeding device, and then the required yarn is placed in the yarn bobbin. The yarn is then fed into the yarn feeding device through the yarn bobbin and guided onto the needle bed for knitting. The installation of the yarn bobbin in the yarn feeding device of most circular knitting machines is relatively troublesome.

[0004] Chinese Patent Publication No. CN220846489U discloses a yarn feeding device for a circular knitting machine, relating to the technical field of yarn feeding devices. It improves upon existing devices where the yarn guide groove and circular plate are fixed together using bolts and nuts. This requires a wrench to loosen the bolts and nuts during installation, consuming significant time and effort and increasing the workload of operators. The new device includes a circular plate and a support plate. The support plate is located on the outer surface of the circular plate, and a base plate is movably connected to its outer surface. An installation component is located on the outer surface of the circular plate, and a fixing component is located on the outer surface of the installation component. The patent utilizes an installation block, an installation groove, and a moving block to install the yarn guide groove onto the circular plate surface, reducing the workload for operators. Furthermore, the locking blocks and grooves ensure a more secure installation of the yarn guide groove, preventing it from detaching from the circular plate, thus saving time and effort.

[0005] In some existing technologies, the yarn bobbins in the yarn feeding devices of most cylindrical knitting machines are relatively troublesome to install, and the structure for limiting and fixing the yarn bobbins mostly uses nuts and threaded rods for fixing. After long-term use, connection fatigue is prone to occur, causing the nuts to loosen or even fall off. Utility Model Content

After long-term use, connection fatigue is likely to occur, resulting in the nut becoming loose or even falling off.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A yarn feeding device for a cylindrical knitting machine includes a counterweight base plate. The cylindrical knitting machine is fixedly connected to the left side of the top of the counterweight base plate. A support mechanism is fixedly connected to the right side of the top of the counterweight base plate. An installation mechanism is fixedly connected to the top of the support mechanism. A limiting mechanism is fixedly connected to the middle of the top of the support mechanism. The support mechanism includes a support base plate. A fixed circular plate is fixedly connected to the top of the support base plate.

[0009] Preferably, the mounting mechanism includes a plurality of mounting rods and two mounting rings.

The bottom of the plurality of mounting rods is fixedly connected to the top of the fixed circular plate. The two mounting rings are mounted on the upper and lower parts of the plurality of mounting rods, and the outer surfaces of the two mounting rings are symmetrically and fixedly connected to limit blocks.

[0010] Preferably, the outer surface of the upper limiting block is symmetrically engaged with an adjusting seat, the inner surface of several adjusting seats is slidably connected with a movable seat, the outer surface of the movable seat is symmetrically slidably connected with a toothed plate, the opposite sides of two toothed plates on the same side are slidably connected with a spring piece, and the top of the movable seat is fixedly connected with a limiting groove seat.

[0011] Preferably, limiting slot seats two are fixedly connected to opposite sides of the top of several adjusting seats. The inner surfaces of limiting slot seats one and two located on the same side are engaged with limiting plate one. The opposite ends of the inner surfaces of several limiting plate one are engaged with limiting plate two. The lower side of the outer surface of the limiting plate two is engaged with a retaining ring. The opposite sides of the outer surfaces of several retaining rings are fixedly connected to the opposite sides of the outer surfaces of several adjusting seats.

[0012] Preferably, each of the several adjusting seats has a support rod fixedly connected to its bottom, and a U-shaped locking block is fixedly connected to the bottom of each support rod. The inner sides of the several U-shaped locking blocks are engaged with the outer surface of the lower mounting ring. A threaded sleeve seat is fixedly connected to the middle of opposite sides of the outer surfaces of the several support rods. A threaded rod is threadedly connected to the inner surface of the threaded sleeve seat. A limit ring is slidably connected to the outer surface of the threaded rod near the threaded sleeve seat.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the implementation of this utility model, by setting up an installation mechanism, the yarn bobbins in the yarn feeding devices of most cylindrical knitting machines are relatively troublesome to install. Moreover, the structure for limiting and fixing the yarn bobbins mostly adopts the method of fixing with nuts and threaded rods. After long-term use, connection fatigue is prone to occur, causing the nuts to loosen or even fall off. Therefore, the nuts can be limited by springs and limiting telescopic rods. When installing the yarn bobbins, the springs and limiting telescopic rods are in a compressed state. Under the elasticity of the springs themselves, there is always an outward pushing force on the nuts, which can prevent them from loosening and falling off. Therefore, the frequency of inspection and retightening of nuts can be reduced, the maintenance cycle can be extended, and the maintenance cost can be reduced.

[0018] 2. In the implementation of this utility model, by setting a limiting mechanism, multiple yarn bobbins are provided, and multiple limiting rods can limit each yarn to prevent the yarn from becoming tangled and messy during feeding. By enhancing the feeding order between yarns, it helps to improve the smoothness of yarn feeding to a certain extent and ensure the continuity of processing. Attached Figure Description
