[0028] As Figures 1-3As shown, the conveying frame 2 drives the fixing device 3 through the linear drive device 18, which is a linear motor set. The linear motor set is a prior art. In use, the fixing device 3 is made close to the flattening roller 5 through the linear drive device 18, and the distance between the fixing device 3 and the flattening roller 5 is gradually increased through the linear drive device 18, so that the metal wire mesh 4 with a longer length can be processed, preventing the problem of poor flattening effect caused by the distance between the winding position and the flattening roller 5 being too far, and ensuring that the metal wire mesh 4 can be uniformly flattened in the entire length range.

[0029] As shown in Figure 4 , 5 , the flattening frame 1 is bolted with a housing 19, which covers the meshing part of the worm 15 and the worm wheel 14, and the extension rod 16 penetrates through the housing 19. By setting the housing 19, the meshing part of the worm 15 and the worm wheel 14 can be protected, and the worm 15 and the worm wheel 14 can also be limited, preventing dust pollution and preventing the meshing from being disconnected due to external force interference or vibration, thereby improving the reliability and safety of the entire transmission system.

The telescopic rod 22 is a prior hydraulic rod or pneumatic telescopic rod 22. In use, the fixed plate 23 is controlled to approach the support plate 21 through the telescopic rod 22, and the metal wire mesh 4 is fixed through the pressure of the fixed plate 23 to the support plate 21, only ensuring the stability of the metal wire mesh 4 in the processing process, but also improving the processing precision and efficiency. The end of the fixed plate 23 and the support plate 21 close to the flattening roller 5 is provided with a rounded corner 24, avoiding the sharp corners directly contacting the metal wire mesh 4, effectively reducing the risk of the metal wire mesh 4 being scratched, and protecting the integrity of the metal wire mesh 4.

[0031] The gap between the upper roller 7 and the lower roller 8 gradually decreases from the flattening roller 5 close to the fixing frame side to the flattening roller 5 away from the fixing frame side. By gradually reducing the gap, the metal wire mesh 4 can gradually receive greater compression force when passing through the flattening roller 5, thereby more effectively eliminating the winding and unevenness, reducing the possibility of repeated flattening, and thereby improving the overall production efficiency.

[0032] As shown in Figure 7 , 8 The upper roller 7 is sleeved with a rubber layer 25. The rubber layer 25 has good friction performance and can significantly improve the friction between the upper roller 7 and the metal wire mesh 4. It helps to ensure that the metal wire mesh 4 can be effectively straightened and fixed during the rolling and leveling process, thereby improving the accuracy and stability of leveling. The rubber layer 25 has a certain elasticity and buffering effect, which can play a protective role when the upper roller 7 contacts the metal wire mesh 4.
