[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 5 As shown, this application provides a warp knitting machine capable of weaving fabrics with different density intervals, including: a frame 1, a needle bed mounting plate 2 installed on the inner side of the frame 1, a comb roller frame 3 connected to one end of the frame 1, and a composite needle plate 4 provided on the inner side of the needle bed mounting plate 2.

[0026] The tongue needle adjustment assembly includes a positioning plate 5, which is located at the top of the needle bed mounting plate 2. A connecting plate 8 is located at the top of the positioning plate 5, and a tongue needle body 11 is located at the top of the connecting plate 8. The tongue needle adjustment assembly is used to adjust the spacing of the tongue needle body 11.

[0027] Specifically, such as Figure 3 As shown, the inner side of the positioning plate 5 is provided with an elliptical groove 6, and the top of the positioning plate 5 is provided with a guide rod 7. The elliptical groove 6 is elliptical in shape, which can improve the adjustment performance during installation.

[0028] Specifically, such as Figure 3 As shown, the connecting plate 8 is connected to the outer top of the guide rod 7, and the top of the connecting plate 8 is provided with an adjusting block 9. The adjusting block 9 is an extension of the connecting plate 8 and can be adjusted at the bottom. The bottom is connected to the guide rod 7 through the connecting plate 8 to control the yarn weaving density adjustment position.

[0029] Specifically, such as Figure 4 As shown, a bidirectional threaded rod 10 is connected to the inner side of the adjusting block 9. The rotation of the bidirectional threaded rod 10 is used to control the position of the tongue needle body 11 on the adjacent sides.

[0030] The guide adjustment assembly includes a positioning frame 12, which is located at the top of the comb roller frame 3. An adjustment rod 13 is provided on the inner side of the positioning frame 12, and a guide plate 17 is provided at one end of the adjustment rod 13. The guide adjustment assembly is used for guiding and adjusting the yarn.

[0031] Specifically, such as Figure 5As shown, an adjusting threaded cylinder 15 is connected to the outside of the adjusting rod 13, and an elastic connector 14 is provided on the outside of the adjusting rod 13. The turning position of the adjusting rod 13 and the adjusting threaded cylinder 15 controls the maximum compression limit position of the moving frame 16. By adjusting the transmission space, different densities of yarn weaving are controlled.

[0032] Specifically, such as Figure 5 As shown, one end of the adjusting rod 13 is connected to the movable frame 16, and the guide plate 17 is disposed inside the movable frame 16. The tension is adjusted by adapting the position of the guide plate 17.

[0033] Specifically, such as Figure 5 As shown, both the upper and lower ends of the guide plate 17 are connected to elastic connecting rods 18, and the guide plate 17 is provided with guide holes 19 inside. The guide holes 19 are used for threading the yarn. The displacement of the guide plate 17 is controlled by the connection of the elastic connecting rods 18, thereby improving the protection of yarn transmission.

[0034] Specifically, such as Figure 5 As shown, the guide plate 17 and the elastic connecting rod 18 are fixedly connected, and the elastic connecting rod 18 and the moving frame 16 are elastically connected. The rod part of the elastic connecting rod 18 can also slide and adjust inside the moving frame 16.

[0035] In this embodiment: when positioning the tongue needle body 11 at the top of the needle bed mounting plate 2, the spacing can be controlled by adjusting the installation position of the positioning plate 5. The position adjustment of the connecting plate 8 at the top can also control the spacing of the tongue needle body 11. The needle pitch adjustment is increased under the contact of the guide roller adjustment, which improves the range of different density adjustment for fabric processing. A guide plate 17 with adjustable position is set at the top of the guide roller frame 3 for yarn guidance and transmission. An adjusting rod 13 and an adjusting threaded cylinder 15 are set on one side of the guide plate 17 for positioning limitation and maximum adjustment, further improving the adjustment performance of different density fabric processing.

[0036] Specifically, this solution involves the following steps: During warp knitting of the fabric, the yarn is guided and transmitted through the needle bed mounting plate 2 and the comb roller frame 3, working together to perform warp knitting. Since different density requirements exist for the fabric being processed, in addition to adjusting the position of the comb roller frame 3 itself, the spacing of the tongue needles 11 can be adjusted by adjusting the installation position of the positioning plate 5 or by rotating the bidirectional threaded rod 10. This allows for adjustment of the fabric processing density. A positioning frame 12 can be extended and installed at the top of the comb roller frame 3. The position of the yarn passing through the internal guide hole 19 can be adjusted by adjusting the position of the guide plate 17 at the top. A moving frame 16 is connected to the outside of the adjusting rod 13. The movement of the moving frame 16 is controlled by rotating the adjusting rod 13 and the adjusting threaded cylinder 15, adapting to and adjusting the processing of fabrics with different densities, thereby improving the processing efficiency of the equipment.
