AI Technical Summary
The connection between the existing forming mesh and the dewatering cylinder is cumbersome and prone to loosening, which can cause the forming mesh to twist or bend, affecting the dewatering quality.
The forming mesh adopts a three-layer structure, with the upper and lower layers using warp and weft threads of different diameters, and the middle layer using paired weft threads connected together. Combined with spike components, clamping plates and cylinder system, it ensures that the forming mesh fits tightly with the dewatering cylinder.
This achieves a stable connection between the forming mesh and the dewatering cylinder, avoiding twisting and bending of the forming mesh and ensuring dewatering quality.
