The first pressing roller body 3 and the first support body 1 clamp the cloth, and when the first motor 31 drives the first pressing roller body 3 to rotate, the cloth can rotate around the first support body 1 and the second support body 2.

A second pressing roller body 22 is arranged on the outer side of the second supporting body 2, the second pressing roller body 22 is installed on a sliding seat 24, and the position of the second pressing roller body 22 is controlled by a first air cylinder 23. When the second pressing roller 22 is close to the second supporting body 2, the second pressing roller 22 clamps the cloth and can drive the cloth to rotate, and the second pressing roller 22 is far away from the second supporting body 2, so that the feeding operation is facilitated.

An air blowing pipe 4 for folding the cloth and a material folding conveyor belt 8 for conveying the cloth folded portion 9b to the inside are provided on the inside of the looped cloth. The number of the air blowing pipes 4 is multiple, and the air blowing openings are distributed and arranged. The folding part 9b of the cloth falls in front of the first supporting body 1 and the second supporting body 2, after the air is blown by the air blowing pipe 4, the folding part 9b is blown to the bottom surface of the winding part 9a, and then the material is supported and conveyed by the material folding conveying belt 8; in the case where the cloth is rotated at the same time, the folded portion 9b and the winding portion 9a of the entire cloth can be folded together.

The first supporting body 1 is an arc-shaped plate body for supporting the inner side surface of the cloth, and the air blowing pipe 4 and the material folding conveying belt 8 are located on the inner side of the arc-shaped plate body. The arc-shaped plate body is provided with a smooth surface, cloth can rotate along the wall surface of the arc-shaped plate body, the air blowing pipe 4 blows the folded part 9b to the inner bottom surface of the arc-shaped plate body, and the folded part 9b is smoothed through the material folding conveying belt 8.

As shown in fig. 1, the material folding conveyor belt 8 is arranged longitudinally, and the conveying direction is perpendicular to the cloth rotating direction. The material folding conveyor belt 8 can be rotatably arranged on a material folding synchronizing wheel 82, and the material folding synchronizing wheel 82 is connected with a material folding driving motor 81.
