Example 1

[0022] As Figure 1As shown, a five-shaft tricot warp knitting machine includes a warp feeding mechanism 1 and a loop forming mechanism 2 mounted on a machine frame 3, the warp feeding mechanism 1 includes a first warp disc head 1-1, a second warp disc head 1-2, a third warp disc head 1-3, a fourth warp disc head 1-4, and a fifth warp disc head 1-5, and the loop forming mechanism includes four guide bars, which include a first guide bar 2-1, a second guide bar 2-2, a third guide bar 2-3, and a fourth guide bar 2-4 in sequence, wherein the warp yarns on the first warp disc head 1-1 and the second warp disc head 1-2 are connected to the first guide bar 2-1 through unwinding respectively, the warp yarn on the third warp disc head 1-3 is connected to the second guide bar 2-2 through unwinding, the warp yarn on the fourth warp disc head 1-4 is connected to the third guide bar 2-3 through unwinding, and the warp yarn on the fifth warp disc head 1-5 is connected to the fourth guide bar 2-4 through unwinding.

[0023] In the utility model, five groups of warp disc heads can be arranged and installed on the machine frame according to actual requirements. As a key component of the warp knitting machine, the increase in the number of warp disc heads not only occupies more installation space, affects the knitting effect (the increase in the warp disc heads increases the transportation distance of the warp yarn, causes the tension distribution of the yarn to be uneven in the knitting process, and affects the production efficiency and the quality of the finished product), but also puts higher requirements on the stability of the whole machine due to its own weight. Therefore, under the constraints of limited installation space and strict safety, the arrangement and installation structure of the five groups of warp disc heads is optimized in embodiment 1, and the specific structure is as follows:

[0024] The first warp disc head 1-1, the second warp disc head 1-2, the third warp disc head 1-3, and the fourth warp disc head 1-4 are rotatably installed on the machine frame 3 from bottom to top on one side of the machine frame 3, and the fifth warp disc head 1-5 is rotatably installed on the other side of the machine frame 3. This layout can make full use of the vertical space, reduce the horizontal occupation, is suitable for scenarios where the space of the factory building is limited, can reduce the gravity center of the machine frame, can avoid excessive weight on one side, balance the stress of the machine frame, significantly enhance the stability of the installation of the machine frame, provide safety protection for the production process, and avoid interference with the components below by using the top space. On the other hand, the vertically arranged warp disc heads can shorten the distance of the yarn from the disc head to the knitting area through layered yarn guide path design, especially optimize the transmission path of the two groups of bottom warp yarns, reduce the tension fluctuation, improve the structural stability of the base fabric, and improve the production efficiency and the quality of the finished product.

[0025] In order to ensure the yarn tension, reduce the yarn swing in the warp yarn transportation process, and ensure the consistency of the warp yarn transportation path, in embodiment 1, a tension adjusting mechanism 4 is arranged between the first guide bar 2-1 and the first warp disc head 1-1, between the first guide bar 2-1 and the second warp disc head 1-2, between the second guide bar 2-2 and the third warp disc head 1-3, between the third guide bar 2-3 and the fourth warp disc head 1-4, and between the fourth guide bar 2-4 and the fifth warp disc head 1-5, for guiding the warp yarn and adjusting the yarn tension.

[0026] In this embodiment 1, the tension adjusting mechanism 4 can be but not limited to the following structure.

[0027] As shown in the drawings, the tension adjusting mechanism 4 comprises several adjusting plates 4-1, a tension rod 4-2 and several tension mounting plates 4-3, the several tension mounting plates 4-3 are arranged on the rack 3 along the axis of the disc head, one end of each adjusting plate 4-1 is rotatably connected with a tension mounting plate 4-3, and the tension rod 4-2 is mounted on the adjusting plate 4-1. Figure 2

[0028] The tension rod 4-2 is used to adjust the yarn tension, control the yarn release speed by applying pressure, ensure the uniform tension of the yarn during weaving, and prevent yarn breakage or fabric defects caused by slackness or tightness. When the disc head gradually decreases with the yarn weaving unwinding, the relative position of the yarn will change, so the position of the tension rod 4-2 can be adjusted by rotating the adjusting plate 4-1, thereby adjusting the yarn tension.

[0029] In the utility model, compared with the existing four comb four shaft warp knitting machine, a warp disc head is additionally increased, so the transmission distance of the base fabric warp yarn is inevitably increased, in order to ensure the stability of the base fabric warp yarn transmission, several yarn passing assemblies 5 are arranged between the first warp disc head 1-1 and the corresponding tension adjusting mechanism 4 and between the second warp disc head 1-2 and the corresponding tension adjusting mechanism 4 in this embodiment 1.

[0030] In this embodiment 1, the yarn passing assembly 5 can be but not limited to the following structure.

[0031] As shown in the drawings, the yarn passing assembly 5 comprises several groups of yarn passing mounting plates 5-1, yarn guide rods 5-2 and several groups of yarn guide bearings 5-3, the several groups of yarn passing mounting plates 5-1 are mounted on the rack 3 along the axis of the disc head, the several groups of yarn guide bearings 5-3 are mounted on the rack 3 along the axis of the disc head, and the yarn guide rod 5-1 is fixedly mounted on the yarn passing mounting plate 5-1 or rotatably mounted on the yarn guide bearing 5-3. Figure 3 In this embodiment 1, the yarn passing assembly 5 is a dual-purpose yarn passing assembly, and those skilled in the art can select the mounting mode of the yarn passing rod according to the type of the yarn and the weaving process. When the yarn is an elastic yarn, the yarn passing rod 5-2 can be rotatably connected to the yarn guide bearing 5-3, so that the yarn passing rod follows the yarn. When the yarn is elastic, rotating the yarn passing rod can help reduce yarn friction and avoid excessive stretching.

[0032] The working principle of the utility model is as follows:

[0033]

[0034] ​​The warp yarns on the first warp yarn disc head 1-1 and the second warp yarn disc head 1-2 are respectively connected to the first gilling bar 2-1 through unwinding, and are used for weaving the base cloth. Compared with the prior art, the variety of warp yarns for weaving the base cloth is increased, thereby increasing the diversity and functionality of the base cloth weaving. For example, elastic warp yarns can be added in the base cloth, and the elastic warp yarns and the base cloth basic warp yarns are arranged on the first gilling bar 2-1 to perform composite weaving of the base cloth, so that the performance of the base cloth can be effectively improved. The warp yarns on the third warp yarn disc head 1-3 are connected to the second gilling bar through unwinding, and are used for weaving the middle layer of the fabric. The warp yarns on the fourth warp yarn disc head 1-4 are connected to the third gilling bar 2-3 through unwinding, and the warp yarns on the fifth warp yarn disc head 1-5 are connected to the fourth gilling bar 2-4 through unwinding, and the two warp yarns are used for weaving the face layer of the fabric.

[0035] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments but can be implemented in other embodiments without departing from the spirit or essential characteristic of the application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
