Description

Technical Field

[0001] This utility model relates to the field of knitting equipment technology, and in particular to a yarn feeding finger of a yarn adjusting mechanism, a yarn adjusting mechanism, and a circular knitting machine. Background Technology

[0002] Currently, due to the needs of fabric pattern knitting, circular knitting machines require the use of different types of yarn during the knitting process, a process completed by a yarn adjustment mechanism. In this mechanism, multiple yarn feeding fingers work together to guide the yarn smoothly into the knitting process. To effectively reduce frictional loss during yarn operation, the key contact parts of the yarn feeding fingers are made of ceramic material, utilizing the excellent wear resistance of ceramic to minimize yarn wear. For example, Chinese Patent CN 21858026U describes an adjustable yarn feeding finger and yarn adjustment mechanism. Because the yarn feeding fingers swing in two positions, the friction position between the yarn and the feeding body changes. When the yarn passes through the feeding body at a non-ideal angle, some wear still occurs. For ultra-fine yarns and highly sensitive yarns, this friction can easily cause fiber breakage or surface fuzzing, thus requiring repeated adjustments to the operating parameters based on the equipment layout. Therefore, how to specifically improve the structure of the yarn feeding fingers is the core technical challenge to be solved in this solution. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a yarn feeding finger and yarn adjusting mechanism, as well as a circular knitting machine, for maintaining a uniform transition of the yarn feeding trajectory and reducing yarn friction.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A yarn feeding finger of a yarn adjusting mechanism includes a finger body, a turntable, a positioning handle, and a yarn threading bead; the turntable is rotatably mounted at the end of the finger body, and a first bolt is provided between the turntable and the finger body to fix the rotation angle of the turntable on the finger body; one end of the positioning handle is locked to the turntable by a second bolt, and the other end extends outward relative to the turntable and is provided with a yarn threading bead; there are several positioning handles, and each positioning handle is arranged at intervals around the axis of the turntable; the yarn threading bead is provided with a through yarn threading hole, and the two ends of the yarn threading hole are provided with arc-shaped guide edges arranged in a ring; the yarn threading bead is made of ceramic material; the yarn passes through the yarn threading hole of each yarn threading bead.

[0005] Furthermore, the positioning handle includes an arc segment and a handle rod segment. The arc segment has a superior arc structure. The middle section of the outer wall of the yarn threading bead has a concave neck that extends inward around the entire outer circumference. The arc segment is fitted onto the concave neck of the yarn threading bead. There are two handle rod segments, and one end of each handle rod segment is connected to the two ends of the arc segment. The handle rod segment is provided with a locking plate. The locking plate is provided with mounting holes. The mounting holes on the two locking plates are correspondingly arranged. After the second bolt passes through the two mounting holes, it is connected to the turntable component. During the tightening process of the second bolt, the two locking plates are clamped together, so that the yarn threading bead remains fitted inside the arc segment.

[0006] Furthermore, the turntable component has mounting positions, which are spaced apart along the edge of the turntable component. Each mounting position has a second screw hole, and the locking plate is inserted into the mounting position. The second bolt passes through the two mounting holes and is locked in place with the second screw hole.

[0007] Furthermore, the positioning handle is made of metal and is deformable, and the deformation allows the yarn threading beads to be placed in a deformed state between the two ends of the arc segment.

[0008] Furthermore, the turntable component is provided with an arc-shaped through hole, which extends in an arc around the axis of the turntable component. The finger body is provided with a first screw hole, the position of which corresponds to the position of the arc-shaped through hole. After the first bolt passes through the arc-shaped through hole, it is locked and connected to the first screw hole.

[0009] Furthermore, the turntable component has a circular groove, and a protruding rotating shaft is provided at the center of the circular groove. The end of the finger body is provided with a disc connecting part, and the center of the disc connecting part is provided with a shaft hole. The finger body is embedded in the circular groove through the disc connecting part and the rotating shaft passes through the shaft hole, forming a rotational connection between the finger body and the turntable component.

[0010] Furthermore, the turntable component has a clearance portion, and a clearance opening is provided between the circular groove and the clearance portion. The clearance opening is for the finger body to pass through, and the clearance portion is used to provide space for the finger body to move during the rotation and adjustment of the turntable component.

[0011] Furthermore, the finger body and the turntable are made of metal.

[0012] A yarn adjusting mechanism includes the yarn feeding fingers of the aforementioned yarn adjusting mechanism.

[0013] A circular knitting machine includes the aforementioned wire adjustment mechanism.

[0014] As can be seen from the above description of this utility model, compared with the prior art, the yarn feeding finger, yarn adjusting mechanism, and circular knitting machine provided by this utility model have the following advantages: 1. The rotating disc for threading yarn in this application adopts an axially spaced arrangement design to ensure that the yarn forms a uniform bending transition path during threading. This structure effectively avoids local stress concentration caused by sharp turns in the yarn, thereby significantly improving the stability of yarn tension.

[0015] 2. The yarn feeding holes are specially designed with curved guide edges at both ends, so that the contact area between the yarn and the yarn feeding granules presents a smooth arc contact shape. Combined with the yarn feeding granules being made of ceramic material with an extremely smooth surface, the coefficient of friction when the yarn passes through is greatly reduced, which not only reduces yarn wear, but also improves the smoothness of operation.

[0016] 3. The turntable allows for flexible configuration of the number of yarn feeders according to the yarn bobbin layout requirements, and can be rotated and precisely positioned at the end of the finger body. This modular design enables the yarn feeding system to quickly adapt to diverse production scenarios and process requirements, significantly improving the equipment's versatility and production line adjustment efficiency.

The finger body 1, turntable 2, and positioning handle 3 are made of metal, while the yarn threading bead 4 is made of ceramic.

[0025] The turntable 2 is rotatably mounted at the end of the finger body 1. A first bolt 5 is provided between the turntable 2 and the finger body 1 to fix the rotation angle of the turntable 2 on the finger body 1. One end of the positioning handle 3 is locked to the turntable 2 by a second bolt 6, and the other end extends outward relative to the turntable 2 and is provided with a threading bead 4.

The threading bead 4 is provided with a through threading hole 41, and the two ends of the threading hole 41 are provided with annular arc-shaped guide edges 42. The yarn passes through the threading hole 41 of each threading bead 4.

[0026] The positioning handle 3 includes an arc segment 31 and a handle segment 32. The arc segment 31 has a superior arc structure, and a concave neck 43 is provided in the middle of the outer wall of the threading bead 4, which is recessed around the entire outer wall. The arc segment 31 is fitted onto the concave neck 43 of the threading bead 4. There are two handle segments 32, and one end of each handle segment 32 is connected to the two ends of the arc segment 31. The handle segment 32 is provided with a locking plate 33, and the locking plate 33 is provided with mounting holes 34. The mounting holes 34 on the two locking plates 33 are correspondingly arranged. The second bolt 6 passes through the two mounting holes 34 and is connected to the turntable 2. During the tightening process of the second bolt 6, the two locking plates 33 are clamped, so that the threading bead 4 is kept fitted inside the arc segment 31. The turntable 2 has mounting positions 21, and each mounting position 21 is arranged at intervals along the edge of the turntable 2. The mounting position 21 is provided with a second screw hole 22. The locking plate 33 is inserted into the mounting position 21, and the second bolt 6 passes through the two mounting holes 34 and is locked to the second screw hole 22. The positioning handle 3 is made of metal and is deformable. Through deformation, the two ends of the arc segment 31 are in a deformable state that allows the yarn threading beads to be placed.

[0027] The turntable component 2 has an arc-shaped through hole 23, which extends arc-shapedly around the axis of the turntable component 2. The finger body 1 has a first screw hole 11, the position of which corresponds to the position of the arc-shaped through hole 23. The first bolt 5 passes through the arc-shaped through hole 23 and locks into the first screw hole 11. The turntable component 2 has a circular groove 24, with a protruding rotating shaft 25 at the center of the circular groove 24. The end of the finger body 1 has a disc connecting part 12, with a shaft hole 13 at the center of the disc connecting part 12. The finger body 1 is inserted into the circular groove 24 through the disc connecting part 12, and the rotating shaft 25 passes through the shaft hole 13, forming a rotational connection between the finger body 1 and the turntable component 2. The turntable component 2 has a clearance part 26, with a clearance opening 27 between the circular groove 24 and the clearance part 26. The clearance opening 27 allows the finger body 1 to pass through, and the clearance part 26 provides space for the finger body 1 to move during the rotation and adjustment of the turntable component 2.

[0028] A yarn adjusting mechanism includes the yarn feeding fingers of the aforementioned yarn adjusting mechanism.

[0029] A circular knitting machine includes the aforementioned wire adjustment mechanism.

[0030] The following detailed implementation process further illustrates this application.

[0031] During circular knitting, the yarn position is changed by a yarn adjusting mechanism, thereby switching the fed yarn. Specifically, the yarn adjusting mechanism drives the feeding finger to swing between two positions, causing the yarn passing through the feeding finger to change between the feeding position and the non-feeding position.

[0032] The yarn passes sequentially through the threading holes 41 of each threading granule 4. The design of the threading granules 4 being spaced apart around the axis of the rotating disk 2 allows the yarn to form a uniform curved transition path as it passes through the threading granules 4. Furthermore, the arc-shaped guide edges 42 designed at both ends of the threading holes 41 ensure that the contact area between the yarn and the threading granules 4 presents a smooth arc contact. At the same time, the threading granules 4 themselves are made of a smooth and flat ceramic material, a material characteristic that significantly reduces the contact friction of the yarn when it passes through.

[0033] In actual operation, the position of the yarn changes as the yarn adjusting mechanism oscillates. In the design of this application, the yarn always maintains a uniform bending transition state. Therefore, during the oscillation of the mechanism, the yarn will pass through at an ideal angle, thus ensuring that the yarn can be continuously and stably delivered to subsequent processes.

[0034] Furthermore, this design boasts high flexibility and adaptability to various operating conditions. The turntable 2 can be flexibly fitted with the required number of yarn feeders 4 according to the actual layout requirements of the yarn bobbins in production. Moreover, the turntable 2 can be rotated and precisely positioned at the end of the finger body 1, enabling the entire yarn feeding system to adapt to more diverse production requirements.

[0035] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be considered as an infringement of the protection scope of the present utility model.
