Description

Technical Field

[0001] This utility model belongs to the technical field of circular knitting machines, and more specifically, it relates to a yarn guiding mechanism for a circular knitting machine. Background Technology

[0002] The circular knitting machine is an important piece of equipment in the knitting industry, featuring a cylindrical structure. It relies on the high-speed rotation of the cylinder or needle plate, combined with yarn feeding and loop forming actions, to weave yarn into various knitted fabrics. This equipment boasts high production speed and efficiency, capable of knitting various weaves such as plain weave, rib weave, and jacquard, meeting the fabric needs of different garments and home textile products, and playing a crucial role in textile production.

[0003] Based on the above, the inventors have discovered the following problems: Currently, most common circular knitting machines on the market have simple yarn guiding mechanisms and lack effective yarn tension adjustment devices. During the high-speed operation of a circular knitting machine, the yarn is affected by various factors, such as uneven yarn thickness, differences in yarn elasticity, and changes in friction during the knitting process, leading to fluctuations in yarn tension. When the yarn tension is unstable, the yarn may become too loose or too tight. Loose yarn is prone to tangling and knotting during the knitting process, affecting the smooth progress of the knitting.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a yarn guiding mechanism for a circular knitting machine in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a yarn guiding mechanism for a circular knitting machine, so as to solve the problem that current circular knitting machines cannot effectively adjust tension during use.

[0006] The purpose and function of this utility model's yarn guiding mechanism for a circular knitting machine are achieved through the following specific technical means:

[0007] A yarn guiding mechanism for a circular knitting machine includes a circular knitting machine body. A yarn guide frame is mounted on the frame of the circular knitting machine body. The yarn guide frame has multiple mounting positions for mounting yarn guiding components. The number of yarn guiding components is the same as the number of mounting positions. Each yarn guiding component includes a yarn guiding ring, a fixed base, an elastic connector, and a mounting part. One end of the elastic connector is connected to the fixed base, and the other end is connected to the mounting part. The yarn guiding ring is mounted in the mounting part. An adjustment device is mounted on the fixed base for adjusting the position and angle of the yarn guiding ring.

[0008] Furthermore, the adjusting device includes a mounting plate installed on a fixed base, and an adjusting bolt is mounted on the mounting plate. The end of the adjusting bolt abuts against the elastic connector. By rotating the adjusting bolt, the elastic force of the elastic connector can be adjusted, thereby controlling the adjustment range of the yarn guide ring.

[0009] Furthermore, the elastic connector is a spring sheet, which is arc-shaped, with its two ends connected to the mounting part and the fixing seat respectively, and the end of the adjusting bolt abutting against the middle of the spring sheet.

[0010] Furthermore, the mounting position is provided with a pair of threaded holes and also includes a first fixing bolt, which passes through the fixing seat and rotates into the threaded holes.

[0011] Furthermore, the mounting part is provided with a blocking step. When one end of the yarn guide ring contacts the blocking step, a portion of the yarn guide ring is located outside the mounting part. It also includes a second fixing bolt, which penetrates the mounting part and contacts the yarn guide ring.

[0012] Furthermore, the mounting position is a groove that matches the fixing seat. When the fixing seat is located in the groove, the threaded hole and the through hole on the fixing seat are aligned.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention relates to a yarn guiding mechanism for a circular knitting machine. By incorporating elastic connectors and an adjustment device, the position and angle of the yarn guide rings can be automatically adjusted according to changes in yarn tension, maintaining stable yarn tension and improving the knitting quality of the circular knitting machine. Furthermore, the yarn guiding assembly is detachable, facilitating replacement and maintenance and reducing operating costs. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a yarn guiding mechanism for a circular knitting machine, including a circular knitting machine body 1. A yarn guide frame 2 is installed on the frame of the circular knitting machine body 1. The installation method of the yarn guide frame 2 and the frame of the circular knitting machine body 1 can be welding or other detachable connection methods.

[0029] The yarn guide frame 2 is provided with multiple mounting positions 3, which are used to install yarn guide components 4. The number of yarn guide components 4 is the same as the number of mounting positions 3. The mounting position 3 is a groove structure, and the shape and size of the groove match the fixing seat 402 of the yarn guide component 4 to ensure that the fixing seat 402 can be accurately and stably installed in the groove. At the same time, a pair of threaded holes 6 are provided in the mounting position 3 for subsequent connection with the fixing seat 402.

[0030] The yarn guiding assembly 4 includes a yarn guiding ring 401, a fixing seat 402, an elastic connector 403, and a mounting part 404. The fixing seat 402 is the basic support component of the yarn guiding assembly 4, and it has a through hole for alignment with the threaded hole 6 in the mounting position 3 on the yarn guide frame 2. During installation, a first fixing bolt 7 is used to pass through the through hole on the fixing seat 402 and rotate into the threaded hole 6 in the mounting position 3, thereby firmly fixing the fixing seat 402 to the yarn guide frame 2. An adjustment device 5 is also installed on the fixing seat 402 for adjusting the position and angle of the yarn guiding ring 401.

[0031] The adjusting device 5 includes a mounting plate 501 mounted on a fixed base 402, which is fixed to the fixed base 402 by welding. An adjusting bolt 502 is mounted on the mounting plate 501, and the adjusting bolt 502 is threadedly connected to the mounting plate 501, with its end abutting against the elastic connector 403. By rotating the adjusting bolt 502, the pressure exerted by the adjusting bolt 502 on the elastic connector 403 can be changed, thereby adjusting the elastic force of the elastic connector 403 and thus controlling the adjustment range of the yarn guide ring 401.

[0032] The elastic connector 403 uses a spring sheet, which is arc-shaped. Both ends of the spring sheet are connected to the mounting part 404 and the fixing seat 402, respectively. One end can be fixedly connected to the mounting part 404 by welding, riveting, or bolting, and the other end is connected to the fixing seat 402 in the same way. The end of the adjusting bolt 502 abuts against the middle of the spring sheet. When the adjusting bolt 502 is rotated to change the pressure on the spring sheet, the spring sheet undergoes elastic deformation, causing the mounting part 404 and the yarn guide ring 401 to adjust their position and angle.

[0033] The mounting part 404 is connected to the elastic connector 403 for mounting the yarn guide ring 401. A blocking step 8 is provided inside the mounting part 404. When the yarn guide ring 401 is installed inside the mounting part 404, one end of the yarn guide ring 401 contacts the blocking step 8. At this time, a portion of the yarn guide ring 401 is located outside the mounting part 404, making it easier to replace the yarn guide ring 401. Simultaneously, the mounting part 404 is also provided with a through hole containing a threaded groove. A second fixing bolt 9 passes through the through hole in the mounting part 404 and contacts the yarn guide ring 401, thereby further fixing the yarn guide ring 401 inside the mounting part 404 and preventing it from shaking or falling off during use.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In use, the fixing seat 402 of the yarn guide assembly 4 is placed into the mounting position 3 of the yarn guide frame 2, so that the through hole on the fixing seat 402 is aligned with the threaded hole 6 in the mounting position 3. Then, the first fixing bolt 7 is inserted through the through hole on the fixing seat 402 and turned into the threaded hole 6 to firmly fix the fixing seat 402 on the yarn guide frame 2.

[0036] Next, insert the yarn guide ring 401 into the mounting part 404, so that one end of the yarn guide ring 401 contacts the blocking step 8 in the mounting part 404. Then, use the second fixing bolt 9 to pass through the through hole on the mounting part 404 and contact the yarn guide ring 401 to further fix the yarn guide ring 401 in the mounting part 404;

[0037] According to actual needs, the adjusting bolt 502 is rotated to change the pressure of the adjusting bolt 502 on the elastic connector 403, thereby adjusting the elastic force of the elastic connector 403. When the yarn passes through the guide ring 401, the elastic connector 403 will automatically undergo elastic deformation according to the change of yarn tension, driving the guide ring 401 to adjust its position and angle to maintain stable yarn tension. Finally, the yarn is passed through the guide ring 401 and wound onto the main body 1 of the circular knitting machine.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
