DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-3 A cloth roll front curling edge spreading system comprises two mounting frames 1, two linear guide rails 2 are fixedly connected between the side walls of the two mounting frames 1 close to each other, the side walls of the two linear guide rails 2 are slidably connected with a sliding block 3, the side wall of the mounting frame 1 is fixedly connected with a cylinder 13, the movable end of the cylinder 13 is fixedly connected with the side wall of the sliding block 3 corresponding to it, and the side wall of the sliding block 3 is rotatably connected with two cloth guide rollers 4.

[0019] The sliding block 3 is provided with an edge spreading mechanism for spreading the rolled edges of the cloth located on the two cloth guide rollers 4, and the edge spreading mechanism includes a fixed plate 5 fixedly connected to the side wall of the sliding block 3, and a blowing plate 10 is connected to the fixed plate 5 through a movable mechanism, and an eagle-beak blowing head 11 is provided on the blowing plate 10, and an air inlet pipe 12 connected to the eagle-beak blowing head 11 is provided on the blowing plate 10.

[0020] The fixed plate 5 is located above the cloth guide roller 4, and the side wall of the eagle beak air blowing head 11 is close to one of the side walls of the cloth guide roller 4, so that the high-pressure gas blown out by the eagle beak air blowing head 11 can flatten the edge of the cloth, thereby avoiding excessive cutting of the edge of the cloth and reducing the waste of the cloth edge.

[0021] The moving mechanism includes two sets of mounting plates 6 fixedly connected to the upper end of the fixed plate 5 through a moving block 9, the side walls of the two sets of mounting plates 6 are respectively rotatably connected to two gears through a rotating shaft 7, the side walls of the two gears are connected to a toothed belt 8, the side wall of the toothed belt 8 is fixedly connected to the side wall of the moving block 9, and the side wall of the moving block 9 is fixedly connected to the side wall of the blowing plate 10.

[0022] Furthermore, the rotation of the two gears can drive the toothed belt 8 to move, and then drive the moving block 9 to move, and then drive the blowing plate 10 to move, so that the edges of fabrics with different widths can be blown flat.

[0023] One end of the rotating shaft 7 close to the mounting frame 1 passes through the side wall of the mounting plate 6 and is fixedly connected to a handwheel 14 . The side wall of the rotating shaft 7 close to the handwheel 14 is threadedly connected to a nut 15 , and the side wall of the nut 15 is tightly fitted to the side wall of the mounting plate 6 .

[0024] Furthermore, when the side wall of the nut 15 is tightly fitted with the side wall of the mounting plate 6, the rotation position of the rotating shaft 7 can be fixed, thereby fixing the moving position of the toothed belt 8, thereby ensuring the position stability of the eagle-beak blowing head 11 for blowing.

[0025] In the utility model, the cloth moves on two cloth guide rollers 4, and the eagle-beak air blowing heads 11 located on the two air blowing plates 10 are in contact with the cloth on one of the cloth guide rollers 4. During the cloth movement, the external high-pressure gas will enter the air inlet pipe 12, and then the high-pressure gas will be blown out through the eagle-beak air blowing head 11, so that the edge of the cloth can be flattened. Figure 3 As shown, excessive cutting of the edge of the fabric is avoided, thereby reducing the waste of the fabric edge;

[0026] When blowing flat the edges of fabrics of different widths, the two nuts 15 are rotated to separate the nuts 15 from the side wall of the mounting plate 6, and then the two hand wheels 14 can be rotated. At this time, the two toothed belts 8 on the two moving mechanisms will move, thereby driving the moving block 9 to move, and then driving the blowing plate 10 to move, so that the two eagle-beak blowing heads 11 can blow flat the edges of fabrics of different widths;

[0027] After adjustment, the nut 15 can be rotated again so that the side wall of the nut 15 fits tightly with the side wall of the mounting plate 6. At this time, the rotation position of the rotating shaft 7 can be fixed, thereby fixing the moving position of the toothed belt 8 to ensure the position stability of the eagle-beak blowing head 11.

Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
