[0020] The following further details the specific embodiments of the present utility model in conjunction with the drawings, so that the technical solutions of the present utility model are easier to understand and master.

[0021] Refer to Figure 1 、 Figure 2 In this embodiment, a hemming device for a sleeve fork machine is provided, which includes a bottom plate 2 and a top plate 1. A plurality of spacer blocks 5 are arranged between the bottom plate 2 and the top plate 1. The bottom plate 2 is fixed to the bottom of the spacer blocks 5, and the top plate 1 is fixed to the top of the spacer blocks 5. In this way, the bottom plate 2 and the top plate 1 are arranged at an upper and lower interval to form a guiding channel therebetween, and the vertical height of the guiding channel is the same as the thickness of the spacer blocks 5.

[0022] The top plate 1 is provided with a folding material groove 11 for placing the fabric. The bottom plate 2 is provided with a sleeve fork die groove 21 corresponding to the position of the folding material groove 11 for the sleeve fork die to extend into.

[0023] A number of hemming devices are arranged around the material folding groove 11 on the top plate 1. The hemming device includes a hemming cylinder and a hemming push plate. The hemming cylinder is installed on the top plate 1, and the hemming push plate is slidably arranged in the guiding channel and extends to the material folding groove 11. The thickness of the hemming push plate is close to the vertical height of the guiding channel. During actual production, the difference between the two is allowed to be between 10 and 30 silk, so that it can be ensured that the hemming push plate will not be clamped too tightly or too loosely.

[0024] The hemming devices are divided into side hemming devices 32 and front hemming devices 31. There are two side hemming devices 32, which are respectively located on the left and right sides of the material folding groove 11; a plurality of front hemming devices 31 are arranged at intervals on the front side of the material folding groove 11. Preferably, there are three front hemming devices 31. For the convenience of description, the hemming push plates on the two side hemming devices 32 are called side hemming push plates 61; the hemming push plates on the three front hemming devices 31 are called front hemming push plates 62, and a number of avoiding grooves are provided on the front hemming push plates 62 to avoid touching other components during material folding.

[0025] Through grooves 12 are provided on the top plate 1 at the front side positions corresponding to each hemming device. Taking the side hemming push plate 61 as an example, the rear end of the side hemming push plate 61 has a connecting portion 611 passing through the through groove 12 and connected to the hemming device. The connecting portion 611 and the side hemming push plate 61 form an L shape, and the same is true for other hemming push plates.

[0026] Pressing assemblies 4 are installed on both the left and right sides of the material folding groove 11. The pressing assembly includes an adjusting frame 41 and a pressing plate 42. The adjusting frame 41 is installed on the top plate 1 and is adjustable left and right relative to the material folding groove 11. The pressing plate 42 is fixed on the adjusting frame 41, and the bottom thereof abuts against the side hemming push plate 61 on the corresponding side hemming device 32.

[0027] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
