technical field [0001] The invention relates to the field of warping machines, in particular to a flat wire warping machine used for flat wire warping. Background technique [0002] The flat wire warping machine is used for warping flat wires. In the warping process, in order to ensure the warping quality of the flat yarn on the pan head, the pressure roller is required to cover the flat yarn on the surface of the pan head to prevent the surface of the pan head from being uneven and the thickness of the pan head uneven during the warping process The problem.

Problems solved by technology

The warping machines in the prior art are generally used for warping ordinary yarns (yarns with a circular cross section). After the yarn comes out of the creel, it passes through the tension control system, and the yarn is directly guided by the pressure roller. It enters the winding of the flat yarn, but due to the special structure of the flat yarn itself, the flat yarn cannot be twisted or deformed during the warping process. There is a certain gap between them. When the flat yarn is directly guided by the pressure roller and enters the pan head, it may fall into the gap between the pressure roller and the pan head from the edge of the pressure roller, and the warping quality of the edge of the pressure roller cannot be guaranteed. Some people may propose to set ribs on the edge of the pressure roller to prevent the flat yarn from slipping, but this shortens the width of the warping machine and affects the number of ends of the warped flat yarn. If the requirements of warp knitting are met, the width of the pressure roller will inevitably be increased, so the volume of the warping machine will inevitably increase, resulting in an increase in the cost of the warping machine

[0004] In the existing pressure roller adjustment mechanism, the pressure roller is driven by the air cylinder to cover the surface of the pan head, but the air cylinder is driven by air. Due to the compressibility of the air, the cylinder drive is not stable. When the pressure of the roller is too high, the air in the cylinder will be compressed, resulting in uneven pressure of the pressure roller, which may cause unevenness on the surface of the warping machine, affecting the quality of warping

[0005] Furthermore, the traction roller in the prior art is a roller body with a smooth surface. When the flat yarn contacts the surface of the roller body of the traction roller, there is an arc surface contact between the flat yarn and the traction roller. During the process, the flat yarn may be overturned to form a twist. In the prior art, in order to avoid the flat yarn from twisting on the traction roller, it is prevented by increasing the tension of the flat yarn, but increasing the tension of the flat yarn will bring The biggest problem is that it is easy to break the wire, and the above problems have affected the warping quality of the flat wire
