DETAILED DESCRIPTION

[0020] In order to make those skilled in the art better understand the present invention, the present invention is further explained in detail below with reference to the accompanying drawings and embodiments. It should be noted that the features in the embodiments and embodiments of the present application can be combined with each other without conflict.

[0021] A typical embodiment of the utility model provides an anti-curling device for elastic fabrics of a sewing machine, which comprises an anti-curling mechanism 1. On this basis, an angle adjustment mechanism 2 is arranged at the rear end of the anti-curling mechanism 1.

[0022] The angle adjustment mechanism 2 includes a clamping plate 204 , a curved groove 201 is formed on the surface of the clamping plate 204 , a telescopic plate 206 is clamped on the inner side of the clamping plate 204 , a second bolt 203 is provided at one end of the telescopic plate 206 , and the second bolt 203 is installed in the curved groove 201 .

[0023] In this embodiment, the angle adjustment mechanism 2 is convenient for adjusting the sewing angle so as to sew fabrics of different shapes. The anti-curling mechanism 1 is convenient for flattening the curling edge of the fabric so that the fabric can be sewn more beautifully and neatly.

[0024] The telescopic plate 206 is composed of an insert plate and an interface plate. The insert plate is inserted into the slot of the interface plate to adjust the length of the telescopic plate 206. The second bolt 203 is selectively installed at different positions in the curved groove 201. During installation, the installation angle is adjusted by rotating the second bolt 203.

[0025] In a preferred embodiment, a handle 202 is fixedly provided on the upper end of the second bolt 203 to facilitate the rotation of the second bolt 203 .

[0026] In a relatively specific implementation, third bolts 205 are provided at both ends of the clamping plate 204 for fixing the clamping plate 204 on the fixing component.

[0027] In a preferred embodiment, the anti-curling mechanism 1 includes a first fixed plate 101, and telescopic blocks 102 are arranged at the front and rear ends of one side of the first fixed plate 101, and a second fixed plate 107 is fixed at the lower end of the telescopic block 102. The middle ends of the first fixed plate 101 and the second fixed plate 107 are respectively fixed with first fixed blocks 104, and a first bolt 103 is connected between the two first fixed blocks 104.

[0028] The first fixing plate 101 can be used to install other mechanisms, and the second fixing plate 107 plays a supporting role. The two first fixing blocks 104 are connected by the first bolts 103, so that the distance between the first fixing plate 101 and the second fixing plate 107 can be adjusted. The telescopic block 102 is a plug plate and an interface plate structure. When the above distance adjustment is performed, the telescopic block 102 prevents the first fixing plate 101 and the second fixing plate 107 from being offset.

[0029] A second fixing block 108 is fixedly disposed at the front end of the first fixing plate 101; two clamping blocks 109 are fixedly disposed at the lower side of the second fixing block 108, and a clamping block 111 is clamped at the lower end of the two clamping blocks 109, a spring 110 is disposed between the clamping block 109 and the clamping block 111, and a rotating rod 112 is disposed at the lower end of the two clamping blocks 111. A baffle 105 is fixedly disposed at one end of the lower surface of the first fixing plate 101.

[0030] During operation, the cloth is placed with the rolled edge facing upward between the first fixed plate 101 and the second fixed plate 107. The baffle 105 is used to flatten the rolled edge of the cloth. The rotating rod 112 is convenient for pressing the flattened cloth, and the cloth is transported for sewing by rotation. The clamping block 109 is clamped with the clamping block 111 to enable it to move. The spring 110 fixed on the inside allows the rotating rod 112 to still be pressed and fixed when used on fabrics of different thicknesses.

[0031] The lower end of the second fixing plate 107 is rotatably provided with a rotating block 106. The rotating block 106 allows the mechanism to rotate, so as to adjust the angle.

[0032] The scope of protection claimed by the present invention is not limited to the above specific implementation methods. For those skilled in the art, the present invention may have various deformations and changes. Any modification, improvement and equivalent substitution made within the concept and principle of the present invention should be included in the protection scope of the present invention.
