[0022] The tension adjustment device of a high-speed warp knitting machine according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] For easier understanding, please refer to Figures 1 to 3 This utility model provides an embodiment of a tension adjustment device for a high-speed warp knitting machine, including a base 1, with a limiting mechanism at the top of the base 1; the limiting mechanism includes a mounting frame 4, a fixing plate 401, a cylinder 7, a connecting frame 8, several limiting plates 9, and a guide ring 6. The fixing plate 401 is integrally formed on the top of the mounting frame 4, the cylinder 7 is fixedly installed on the top of the fixing plate 401, the connecting frame 8 is fixedly installed on the output end of the cylinder 7, several limiting plates 9 are fixedly installed on both sides of the connecting frame 8, and the guide ring 6 is fixedly installed on both sides of the guide ring 6.

[0025] It should be noted that by setting a limiting mechanism, when adjusting the yarn tension, the yarn is supported from below upwards. The mounting frame 4 and the limiting plate 9 surround the yarn in the middle, and the mounting frame 4 and the limiting plate 9 are close to the yarn, which can block the yarn support and reduce the fluctuation at the contact point between the yarn and the tension adjustment device. Moreover, the space between the mounting frame 4 and the limiting plate 9 can be adjusted according to the thickness of the yarn. The cylinder 7 drives the connecting frame 8 and the limiting plate 9 to move, and the guide ring 6 supports the contact point between the yarn and the tension adjustment device.

The limiting plate 9 is installed at an angle on both sides of the connecting frame 8. The limiting plate 9 is slidably installed on the corresponding connecting slot 5 wall. The output end of the cylinder 7 extends to the bottom of the fixed plate 401. The limiting plate 9 and the corner of the mounting frame 4 form a limiting space.

[0027] It should be noted that by setting the connecting groove 5, the connecting frame 8 and the mounting frame 4 are installed alternately, so that the connecting frame 8 can move smoothly. The two ends of the guide ring 6 are outwardly flipped arcs, which can protect the yarn when supporting the yarn and reduce the friction on the yarn.

[0028] In some embodiments, such as Figure 2 As shown, a second limiting block 11 is fixedly installed at the top corner of the mounting bracket 4, and a first limiting block 10 is fixedly installed at the bottom of the connecting bracket 8.

[0029] It should be noted that the first limiting block 10 and the second limiting block 11 are installed by screws. By setting the first limiting block 10 and the second limiting block 11, the friction between the yarn and the mounting frame 4 and the limiting plate 9 can be reduced.

[0030] Example 2

The moving block 3 is slidably installed on the inner wall of the base 1, and the mounting bracket 4 is fixedly installed on the top of the moving block 3.

[0032] It should be noted that by setting the electric push rod 2, the moving block 3 and the mounting frame 4 can be raised and lowered to support the yarn and adjust the yarn tension.

[0033] In this utility model, the electric push rod 2 and the cylinder 7 are known components and will not be described in detail here.

[0034] Working principle: When using the tension adjustment device, the yarn is threaded through the guide ring 6 on one side, passing between the mounting frame 4 and the limiting plate 9, and then exiting through the guide ring 6 on the other side. The electric push rod 2 is activated, which drives the mounting frame 4 to rise and fall through the moving block 3. The tension of the yarn is adjusted by the support strength of the guide ring 6 on the yarn.
