Description

Technical Field

[0001] This utility model relates to the field of knitting equipment technology, specifically to a yarn feeder for a circular knitting machine. Background Technology

[0002] A yarn feeder is a structure used to guide the yarn to the appropriate position on the knitting needle.

[0003] By adjusting the preset orientation of the yarn feed nozzle, the angle between the yarn feed nozzle and the knitting needle can be changed, thereby reducing the friction generated during the yarn feeding process.

[0004] However, due to the fixed angle adjustment, in the weaving of patterned fabrics that require a single yarn feeder to feed multiple yarns, the needles at the pattern position will change, meaning that a single preset angle is difficult to meet the need to reduce friction for multiple yarns.

[0005] To address the above problems, a technical solution for a yarn feeding nozzle is proposed. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing a yarn feeding nozzle for a large circular knitting machine.

A rotating component is disposed inside the outer shell and rolls against the inner wall of the outer shell. A plurality of yarn-threading openings connecting the two openings are surrounded between the rotating component and the outer shell. The plurality of yarn-threading openings are distributed in a unidirectional spiral. The weight of the rotating component drives the rotating component to tend towards a stationary state.

[0008] The present invention is further configured to include a yarn guide plate detachably connected to the mounting frame via a second bolt, wherein the mounting frame and the yarn guide plate can be positioned at an angle between them along the axis of the second bolt, and the yarn guide plate is formed with a plurality of guide holes facing a plurality of yarn insertion openings.

[0009] The present invention is further configured such that: the vertical cross-section of the yarn guide plate is L-shaped, and one end of the yarn guide plate is disposed between the mounting frame and the second bolt.

[0010] The present invention is further configured such that an elastic ring is fixedly provided on the inner wall of the guide hole.

[0019] 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. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] A type of yarn feeder for a large circular knitting machine, such as Figures 1 to 4As shown, it includes a mounting frame and a yarn guide plate 3 detachably connected to the mounting frame via a second bolt. The mounting frame and the yarn guide plate 3 can be positioned along the axis of the second bolt to determine the included angle between them. The vertical cross-section of the yarn guide plate 3 is L-shaped. One end of the yarn guide plate 3 is located between the mounting frame and the second bolt. An outer shell 4 is fixedly mounted on the mounting frame. The two ends of the outer shell 4 have circular openings with rounded edges. A rotating component 5 is installed inside the outer shell 4 and rolls around its center ball. Six yarn-feeding ports 6 that connect two openings are surrounded between the rotating component 5 and the outer shell 4. The six yarn-feeding ports 6 are arranged in a unidirectional spiral. The direction of the spiral is the same as the direction in which the yarn passes through the yarn-feeding ports 6 and is woven into the position of the un-lifted needle on the circular knitting machine. The yarn guide plate 3 has six guide holes 31 formed in the direction of the yarn-feeding ports 6.

[0021] After the yarn guide plate 3 and the mounting frame are locked onto the circular knitting machine with the second bolt, in the initial state, the knitting needle is in a low position, and the yarn passing through the yarn entry port 6 is guided by the inner wall surrounding the yarn entry port 6 and enters the yarn at a preset angle.

[0022] When the knitting needle is raised to a high position, the angle between the knitting needle and the horizontal plane increases as the distance between the knitting needle and the yarn feed opening 6 decreases. At this time, the yarn abuts against the surface of the rotating part 5 and pushes the rotating part 5 to roll. At this time, the angle at which the yarn enters the yarn is the angle that minimizes the friction on the yarn. After the yarn enters the yarn, the knitting needle returns to the low position. At this time, the weight of the rotating part 5 drives the rotating part 5 to tend to a stationary state, that is, the initial state.

[0023] When different yarns need to be inserted through the yarn feeder 6, the yarns are pulled by the knitting needles and driven by the rotating part 5, so that the yarns can be inserted at an angle with minimal friction.

[0024] like Figures 1 to 4 As shown, in order to balance the traction force of the yarn on the yarn by the reset effect of the rotating part 5, the rotating part 5 is provided with a receiving groove 51 whose axis passes through its rolling axis and center of gravity. The receiving groove 51 contains a counterweight 7. The counterweight 7 has a spherical structure, that is, part of the weight of the rotating part 5 is replaced by a counterweight 7 with replaceable weight. The shape of the counterweight 7 can ensure that the overall center of gravity is kept on the line connecting the rotating part 5 without the counterweight 7 and the rotation center of the rotating part 5.

[0025] In order to reduce the friction between the yarn and the guide plate 3 when the yarn passes through the guide hole 31, an elastic ring made of smooth rubber material is fixedly provided on the inner wall of the guide hole 31. Considering the convenience of production and installation of the outer shell 4 and the rotating part 5, the mounting frame includes an outer cover 1 and a bracket 2. The outer cover 1 and the bracket 2 are detachably connected by several first bolts. The end faces of the outer cover 1 and the bracket 2 facing the outer shell 4 are provided with fitting grooves. The outer surface of the outer shell 4 is integrally formed with a fitting block 41 embedded in the fitting groove.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
