[0020] The utility model is described in detail below in conjunction with specific embodiments.

[0021] Embodiment 1:

[0022] The two-component cast polyurethane 1 with a hardness of 95A after curing is preheated and vacuumed, and is evenly mixed and poured onto the steel mesh belt 2 with fixed woven wire by a pouring machine. The front and rear ends of the steel mesh belt 2 are fixed and kept in a tensioned state with a tensioning force of 2N / mm. The steel mesh belt 2 is placed in a molding groove for primary curing.

[0027] It should be noted that the utility model adopts a two-component cast polyurethane 1 cast steel mesh belt to form an integral coiling machine belt. The CPU is evenly distributed inside the steel mesh belt 2. The CPU and the steel mesh are completely covered to ensure that no stratification occurs during use. In addition, especially under working conditions with the presence of wetting media such as oil, its wear resistance is often several to dozens of times that of ordinary rubber materials. The CPU also has the characteristic of adjustable hardness range.
