Description

Technical Field

[0001] The utility model relates to the technical field of warp knitted fabric processing, in particular to a shrinkage-proof warp knitted fabric manufacturing machine. Background Art

[0002] In the textile industry, warp knitted fabrics are widely used due to their structural stability and production efficiency. However, warp knitted fabrics may encounter shrinkage problems during production and use, which will affect the dimensional stability and final quality of the product. In order to solve this problem, the research and development of anti-shrinkage warp knitted fabric manufacturing machines has become particularly important.

[0003] For example, a Chinese patent discloses "a warp knitting machine with anti-shrinkage" (patent number: CN219751397U), which includes a machine body; a rotating motor is fixedly connected to one side of the machine body, and a conveying roller is fixedly connected to the output end of the rotating motor; the warp knitted fabric is rolled up on the winding roller, and then the crank is turned to drive the bidirectional screw to rotate. When the bidirectional screw rotates, the distance between the two sets of baffles can be adjusted to provide a limiting effect for both sides of the warp knitted fabric to prevent the warp knitted fabric from being offset. Then, the two sets of rotating motors can be started to drive the conveying roller to rotate, which can drive the warp knitted fabric to move and reel. At the same time, the connecting block will rotate and drive multiple sets of flattening rods to rotate, so that the flattening rods can touch the surface of the warp knitted fabric, so that the surface of the warp knitted fabric is evenly stressed. The above patent has the advantage of avoiding wrinkles on the warp knitted fabric, thereby making the surface of the warp knitted fabric tend to be flat.

[0004] However, in the above-mentioned warp knitting process, since the side edges of the warp knitted fabric are easily curled during the production process, the above-mentioned solution is difficult to solve the problem of curling, thereby affecting the weaving quality of the warp knitted fabric.

DETAILED DESCRIPTION

[0021] The utility model embodiment provides a shrinkage-proof warp knitted fabric manufacturing machine, such as Figure 1-3 As shown, it includes a base 11, a side plate 12, a rotating shaft 13, a motor 14, a transmission roller 15, a limiting bottom plate 16, a limiting side plate 17, a torsion spring 18, a first slot 20, a spring 21, a sliding block 22, a side limiting block 23, a second opening 24, and a flattening roller 25.

[0022] like Figure 1-3 As shown, the side plates 12 are fixedly connected to the base 11, and a warp knitting device is arranged on the base 11. A rotating shaft 13 is rotatably connected inside the two side plates 12, and a motor 14 is arranged at one end of the rotating shaft 13. A transmission roller 15 and two limiting assemblies are fixedly sleeved on the outer circumferential surface of the rotating shaft 13. The limiting assemblies include a limiting bottom plate 16 and a limiting side plate 17. The limiting side plate 17 is fixedly connected to the limiting bottom plate 16, and the limiting bottom plate 16 is rotatably connected to the rotating shaft 13. A torsion spring 18 is also sleeved on the rotating shaft 13, and one end of the torsion spring 18 is fixedly connected to the limiting bottom plate 16, and the other end of the torsion spring 18 is fixedly connected to the side plate 12.

[0023] A first slot 20 is provided on the limiting bottom plate 16, and a spring 21 is provided in the first slot 20. One end of the spring 21 is fixedly connected to a side wall of the first slot 20, and the other end of the spring 21 is fixedly connected to a sliding block 22. The sliding block 22 is slidably connected to the first slot 20, and a side limiting block 23 is fixedly connected to the side of the sliding block 22 close to the limiting side plate 17.

[0024] The thickness of the limiting side plate 17 gradually decreases from the long chord vertex of the limiting bottom plate 16 to the short chord vertex of the limiting bottom plate 16 , and a chamfer is provided at one end of the limiting side plate 17 close to the long chord vertex of the limiting bottom plate 16 .

[0025] A second opening 24 is provided on the side limit block 23, and a flattening roller 25 is rotatably connected in the second opening 24. The second opening 24 is provided on a side of the side limit block 23 close to the limit side plate 17. An arc surface is provided on the side of the side limit block 23 close to the limit side plate 17, and an anti-slip pattern is provided on the outer circumferential surface of the flattening roller 25.

[0026] When the present scheme is used to weave warp knitted fabric, first, the warp knitting device knits the monofilament into warp knitted fabric, and both sides of the warp knitted fabric are fed in from between the limiting side plate 17 and the side limiting block 23. Then, the motor 14 is started, and the motor 14 drives the transmission roller 15 to rotate through the rotating shaft 13. The transmission roller 15 transports the warp knitted fabric from one end of the side plate 12 to the other end of the side plate 12. The side edge of the warp knitted fabric pushes the side limiting block 23 through the flattening roller 25. The side limiting block 23 compresses the spring 21 through the sliding block 22, so that the elastic potential energy of the spring 21 increases, and the spring 21 generates elastic force on the sliding block 22. The sliding block 22 generates pressure on the flattening roller 25 through the side limiting block 23, so that the flattening roller 25 generates pressure on the main body of the warp knitted fabric. Finally, the main body of the warp knitted fabric contacts the flattening roller 25, and the flattening roller 25 rolls with the main body of the warp knitted fabric, and the flattening roller 25 flattens the main body of the warp knitted fabric.
