Description

Technical Field

[0001] This utility model relates to the field of knitting machine technology, specifically to a yarn management mechanism for knitting machines. Background Technology

[0002] A knitting machine is a textile equipment that uses the reciprocating motion of needles and threads in its working part to interweave and weave knitting threads to form the desired textiles, replacing traditional hand weaving techniques. A single textile may require dozens or even hundreds of knitting threads, so a mounting frame is set up to place all the winding sleeves in a unified manner, which facilitates the changing and management of knitting threads. A thread guiding mechanism is set up between the mounting frame and the knitting machine to guide the knitting threads.

[0003] In textile manufacturing, the needle and thread on a knitting machine undergo a reciprocating motion. Therefore, the pulling of the yarn is not continuous but intermittent. During this repeated pulling, sudden pulling and stopping of the yarn can easily cause breakage. For example, application number CN202323613680.8, "A yarn guiding device for a knitting machine," utilizes a buffer spring inside the yarn bobbin to alleviate yarn tension. However, using only a buffer spring inside the bobbin results in a large deformation between the outer and inner bobbins, causing them to lose their coaxiality. This makes the outer bobbin prone to wobbling during yarn guiding, leading to poor yarn guiding efficiency.

[0004] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this invention is to provide a yarn-feeding mechanism for knitting machines to solve the problems mentioned in the background art.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a knitting machine yarn conditioning mechanism, comprising two clamping plates, a fixed shaft between the two clamping plates, a yarn spool sleeved on the fixed shaft, the yarn spool comprising an inner spool and an outer spool, the inner spool being sleeved on the fixed shaft, the outer spool being sleeved outside the inner spool, and the inner spool and the outer spool being connected by several buffer components.

[0009] Preferably, the outer side of the inner cylinder is provided with several planes, the inner side of the outer cylinder is provided with several planes, the planes on the outer side of the inner cylinder and the planes on the inner side of the outer cylinder correspond to each other, and the buffer assembly is disposed between the planes on the outer side of the inner cylinder and the planes on the inner side of the outer cylinder.

[0010] Preferably, the planes on the outer side of the inner cylinder and the planes on the inner side of the outer cylinder are evenly distributed at equal intervals on their respective arc surfaces.

[0011] Preferably, the buffer assembly includes a telescopic rod, a counterweight bead, and a spring. The telescopic rod is fixed on the plane outside the inner cylinder, and a counterweight bead is fixed at the tail end of the telescopic rod. One end of the spring is fixedly connected to the counterweight bead, and the other end is fixedly connected to the plane inside the outer cylinder.

[0012] Preferably, a counterweight ring is fixed on the counterweight bead. Beneficial effects

[0013] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The yarn management mechanism of this utility model is provided with a buffer assembly of counterweight beads and counterweight rings. During the rotation of the yarn drum, due to the centrifugal force, the counterweight beads and counterweight rings compress the springs. Since the centrifugal force is the same, the springs in each buffer assembly are compressed to the same degree. The inner and outer drums always maintain coaxial and stable rotation, which is not easy to cause shaking and has a good yarn management effect. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] This utility model embodiment provides a yarn-feeding mechanism for a knitting machine, such as... Figure 1-2 As shown, it includes two clamping plates 1, with a fixed shaft 2 between the two clamping plates 1. A bobbin 3 is sleeved on the fixed shaft 2. The bobbin 3 includes an inner cylinder 31 and an outer cylinder 32. The inner cylinder 31 is sleeved on the fixed shaft 2, and the outer cylinder 32 is sleeved outside the inner cylinder 31. The inner cylinder 31 and the outer cylinder 32 are connected by several buffer components. Through the buffer components, the inner cylinder 31 and the outer cylinder 32 remain coaxial when the bobbin 3 rotates.

[0019] Reference Appendix Figure 2 The outer side of the inner cylinder 31 is provided with several planes, and the inner side of the outer cylinder 32 is provided with several planes. The planes on the outer side of the inner cylinder 31 and the planes on the inner side of the outer cylinder 32 correspond to each other. The buffer assembly is set between the planes on the outer side of the inner cylinder 31 and the planes on the inner side of the outer cylinder 32. The planes on the outer side of the inner cylinder 31 and the planes on the inner side of the outer cylinder 32 are evenly distributed at equal intervals on their corresponding arc surfaces, so that the inner cylinder 31 and the outer cylinder 32 are subjected to consistent forces in all directions when they rotate, thereby achieving coaxial rotation.

[0020] Reference Appendix Figure 2 The buffer assembly includes a telescopic rod 4, a counterweight bead 5, and a spring 6. The telescopic rod 4 is fixed to the outer plane of the inner cylinder 31, and the counterweight bead 5 is fixed to the tail end of the telescopic rod 4. One end of the spring 6 is fixedly connected to the counterweight bead 5, and the other end is fixedly connected to the inner plane of the outer cylinder 32. When the spool 3 rotates, the counterweight bead 5 is compressed by centrifugal force, and because the centrifugal force is the same (the counterweight bead 5 is the same, and the angular velocity is the same), the springs 6 in each buffer mechanism are compressed uniformly, realizing the coaxial rotation of the inner cylinder 31 and the outer cylinder 32. When the spring 6 is compressed, the outward force is large, and the outer cylinder 32 is supported by the springs 6 in all directions, making it more stable. A counterweight ring 7 is fixed on the counterweight bead 5 to increase the centrifugal force and make the spool 3 more stable when rotating.

[0021] This utility model discloses a yarn management mechanism for a knitting machine, which includes a buffer assembly with a counterweight bead 5 and a counterweight ring 7. During the rotation of the yarn spool 3, due to the centrifugal force, the counterweight bead 5 and the counterweight ring 7 compress the spring 6. Since the centrifugal force is the same, the spring 6 in each buffer assembly is compressed to the same degree. The inner cylinder 31 and the outer cylinder 32 always maintain coaxial and stable rotation, which is not easy to cause shaking and has a good yarn management effect.

[0022] 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 variations 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.
