[0017] 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.

[0018] Auxiliary yarn clearing devices for yarn feeders, such as Figures 1 to 4 As shown, the device includes a yarn feeder 1 that can straighten the passing yarn and a front probe. Both the yarn feeder 1 and the front probe are mounted on the yarn feeder, and both are conventional technologies in the field. Their structure and principles will not be elaborated upon here. To more thoroughly clean the floating yarn on the yarn surface, a base 3 is provided on the yarn feeder 1. Several yarn clearing components 2 are arranged around the periphery of the base 3. The first line connecting the two ends of the straightened yarn surface, held by the yarn clearing components 2, forms an angle unequal with the second line connecting the center of the circle around the base 3 to the corresponding yarn clearing component 2. Considering the most... The uniform cleaning effect is achieved by varying the included angles from the yarn feeder 1 to the front probe. The calculated changes in included angles of adjacent yarn cleaning components 2 are all equal, and the change multiplied by the number of yarn cleaning components 2 is an integer multiple of 180 degrees. In actual use, the number of yarn cleaning components 2 is determined according to the quality of the yarn. If the yarn quality is good and there are few floating threads on the surface, the number of yarn cleaning components 2 required can be reduced accordingly. Typically, three, four, and six yarn cleaning components 2 are set. Compared with the prior art, the auxiliary yarn cleaning device of this application can perform multiple effective cleanings on the periphery of the yarn.

[0019] like Figures 2 to 4As shown, in order to achieve the optimal yarn clearing effect by adjusting different numbers of yarn clearing assemblies 2, the yarn clearing assembly 2 includes a connector 21, a positioning member, a receiving member 23, and a yarn clearing plate 24. The receiving member 23 has a yarn clearing opening 231 on its inner side for accommodating the yarn through which it passes. The positioning member is fixed to the base 3 by the connector 21 and is used to constrain the orientation of the yarn clearing opening 231. The receiving member 23 has two receiving grooves 233 that communicate with the yarn clearing opening 231. The two receiving grooves 233, which are symmetrically distributed along the yarn clearing opening 231, each accommodate one yarn clearing plate 24. The positioning member includes a locking member 25 and a spring ring that is rotatably connected to the receiving member 23. 22. The outer side of the receiving member 23 is provided with an annular groove 232 that fits into the inner wall of the spring ring 22. The spring ring 22 is a non-closed ring structure. The two ends of the spring ring 22 are respectively set as a first edge portion 221 and a second edge portion 222. One end of the locking member 25 is rotatably connected to the first edge portion 221. The other end of the locking member 25 can be rotated to form a snap-fit ​​with the second edge portion 222, so that the spring ring 22 clamps the receiving member 23. The cross section of the base 3 near one end of several connecting members 21 is annular. The connecting members 21 are inserted into the base 3 from the outside to the inside. The end of the connecting member 21 that protrudes from the inner side of the base 3 is fixed to the base 3 by a pin.

[0020] like Figure 3 As shown, considering the convenience of the yarn passing through the yarn clearing opening 231, firstly, the position between the first edge 221 and the second edge 222 can be opened by operating the locking member 25. Secondly, the receiving member 23 has a U-shaped structure and the yarn clearing opening 231 is located inside the U-shaped structure. That is, the yarn can pass through all the components on the yarn feeder completely and then be clamped by several pairs of yarn clearing plates 24 in sequence.

[0021] like Figures 2 to 4 As shown, considering that several structures on the yarn feeder that come into contact with the yarn are usually not rigidly connected in order to allow the yarn to be transmitted more smoothly, a threaded rod is fixedly provided at the end of the base 3 away from the connector 21. The threaded rod passes through the yarn feeder 1. Nuts 5 and springs 4 are respectively provided on both sides of the threaded rod on the yarn feeder 1. The springs 4 are sleeved on the threaded rod, and the nuts 5 are threadedly connected to the threaded rod.

[0022] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. 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.
