[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments; the technical features designed in different implementation modes of the utility model described below can be combined with each other as long as they do not conflict with each other; based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof all mean "at least including".
[0031] In order to facilitate a clear understanding of the technical solution of the utility model, the structure of the yarn feeder is first explained. In the prior art, circular looms are generally divided into single-sided circular looms and double-sided circular looms. Single-sided circular looms have only one needle plate, and double-sided circular looms have double-sided needle plates. The double-sided needle plate requires two yarns for weaving, so double-sided circular looms need to use double-hole yarn feeders.
[0032] like Figure 1 As shown, two thread holes are arranged on the two-hole yarn feeder. Limited by the volume of the overall yarn feeder and the yarn feeding angle requirements, the two thread holes can only be designed to be relatively small, or one large and one small. If the thread holes are to be enlarged, the overall volume of the yarn feeder needs to be increased, or the yarn feeding angle may be affected, thereby affecting the overall knitting work.
[0033] In order to solve the above technical problems, at least one of the above advantages or other advantages can be achieved. Figure 2 and Figure 3 , Figure 2 It is a structural schematic diagram of a circular loom structure with easy yarn change provided by an embodiment of the utility model; Figure 3 It is a side view of a circular loom structure with easy yarn change provided by one embodiment of the utility model.
[0034] One embodiment of the present invention provides a circular loom structure that is easy to change yarns. Figure 2 and Figure 3 As shown in FIG. 1 , the circular loom structure for easily changing yarns includes an upper cam 10 and a lower cam 20 .
[0035] Please combine Figure 1 , Figure 2 See also Figure 3The upper triangle 10 is provided with a needle disk 30 and a yarn feeding nozzle 40, the needle disk 30 is provided with an upper knitting needle 50, the yarn feeding nozzle 40 is movably connected to the upper triangle 10, and the yarn feeding nozzle 40 is provided with a first thread hole 60, and the yarn 70 can pass through the first thread hole 60 to be connected to the upper knitting needle 50 or the lower knitting needle 100.
[0036] In specific implementation, the upper cam 10 is fixed on the circular loom, and the needle disk 30 is arranged on the upper cam 10. The upper cam 10 can control the knitting track of the upper knitting needle 50 on the needle disk 30. The yarn feeder 40 is movably connected to the upper cam 10 and is located above the knitting needle 50. Only one first thread hole 60 is arranged on the yarn feeder 40. Preferably, the diameter of the first thread hole 60 is much larger than the yarn 70, so that it is more convenient to replace the yarn 70. The yarn 70 can pass through the first thread hole 60 and be connected to the upper knitting needle 50 or the lower knitting needle 100.
[0037] A needle cylinder 80 and a yarn guide 90 are provided on the lower triangle 20. A lower knitting needle 100 is provided on the needle cylinder. The lower knitting needle 100 is perpendicular to the upper knitting needle 50. The yarn guide 90 is movably connected to the lower triangle 20. A second thread hole 110 is provided on the yarn guide 90. The yarn 70 can pass through the second thread hole 110 and be connected to the upper knitting needle 50 or the lower knitting needle 100.
[0038] In specific implementation, the lower cam 20 is fixed on the circular loom. The lower cam 20 is relatively perpendicular to the upper cam 10. The lower cam 20 is provided with a needle cylinder 80, and the lower cam 20 can control the knitting track of the lower knitting needle 100 on the needle cylinder 80. When knitting, the upper knitting needle 50 and the lower knitting needle 100 are perpendicular to each other and intertwined with each other.
[0039] The yarn guide 90 includes a yarn guide piece 91 and a base 92. The yarn guide piece 91 is located above the base 92 and connected to the base 92. The base 92 is movably connected to the lower triangle 20 through a connecting piece 120. Preferably, the yarn guide piece 91 and the base 92 are integrally formed to improve the stability on the lower triangle 20.
[0040] The second thread hole 110 is provided on the yarn guide plate 91. The yarn 70 can pass through the second thread hole 110 and be connected to the upper knitting needle 50 or the lower knitting needle 100. Preferably, the diameter of the second thread hole 110 is much larger than the wire diameter of the yarn 70, so that it is more convenient to replace the yarn 70.
[0041] When the yarn 70 needs to be replaced, the yarn feeder 40 is rotated upward to change the thread, and the second thread hole 110 can directly change the thread. After the replacement is completed, the yarn feeder 40 is rotated downward, and the yarn 70 passes through the first thread hole 60 and / or the second thread hole 110 and is accurately fed into the upper knitting needle 50 and / or the lower knitting needle 100.
[0042] It is understandable that the yarn guide 90 is completely independent of the circular loom as a whole. Therefore, in actual application scenarios, yarn guides with different heights and different diameters of the second wire holes 110 can be replaced according to specific production needs to meet different production needs.
[0043] In some preferred embodiments, the yarn guide 90 is L-shaped to further improve the stability on the lower cam 20 .
[0044] In some preferred embodiments, the yarn guide 90 may further be provided with a third thread hole 130 , which is located lower than the second thread hole 110 on the yarn guide 90 , and the yarn 70 can pass through the third thread hole 130 to be connected to the lower knitting needle 100 .
[0045] In a specific implementation, in order to reduce the operation of replacing the yarn guide 90, a third thread hole 130 may be provided on the yarn guide 90, and the position of the third thread hole 130 on the yarn guide plate 91 is lower than the second thread hole 110. When the yarn 70 passes through the third thread hole 130 and is connected to the lower knitting needle 100, the yarn feeding angle is different from that of the second thread hole 110 to meet different production requirements without frequently replacing the yarn guide 90. Preferably, the diameter of the third thread hole is much larger than the wire diameter of the yarn.
[0046] It should be noted that, in actual application, the second wire control 110 and the third wire hole 130 are in a state of choosing one from the other, that is, the yarn 70 needs to pass through one of the two according to production needs and be connected to the lower knitting needle 100.
[0047] In some preferred embodiments, the inner surfaces of the first thread hole 60 , the second thread hole 110 and the third thread hole 130 are smooth and rounded surfaces, which can reduce friction and avoid damaging the yarn 70 .
[0048] The utility model also provides a circular loom, which comprises a plurality of circular loom structures for easily changing yarns as described in any one of the above items.
[0049] To sum up, the utility model provides a circular loom structure and circular loom with easy yarn change. Compared with the prior art, a yarn guide is set by making use of the original hole position on the lower triangle. The yarn can pass through the second wire hole or the third wire hole on the yarn guide to replace one of the wire holes on the yarn feeding mouth, thereby releasing the space of the yarn feeding mouth, so that the diameter of the first wire hole on the yarn feeding mouth can be expanded. The diameter of the second wire hole or the third wire hole on the yarn guide can be set according to specific needs, so as to achieve the effect of easy replacement of yarn or avoiding yarn blocking the wire hole without increasing the volume of the yarn feeding mouth or affecting the yarn feeding angle.
[0050] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the utility model can be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background technology at the same time. Those skilled in the art should understand that the content not mentioned in a claim should not be used as a limitation on the claim.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
