in order to further facilitate the guiding and discharging effect of the over-stitched fabric, in this embodiment, the discharging guide rod bodies 37a and 37b for limiting and guiding the fabric are arranged on the discharging mounting frame 31 and the swing arm 34; the discharging guide rod bodies 37a and 37b are provided with a left discharging limiting cam 38a and a right discharging limiting cam 38b which are used for limiting and guiding the two sides of the overedged fabric; particularly preferably, each of the discharging limit cams 38a and 38b is mounted on the discharging guide rod bodies 37a and 37b through a fastener, and the discharging limit distance between the left discharging limit cam 38a and the right discharging limit cam 38b is adjusted by changing the connecting position of the fastener, so that the structure can be beneficial to adjusting the discharging limit distance according to the width of the finished seam covering 2c, and meanwhile, the good discharging limit guide function of the finished seam covering is not influenced;

the embodiment further provides a tension-free discharging cloth placing mechanism 30 which is composed of a traction cloth guide driving roller 32, a swing arm 34 driven by a cloth placing motor 33 and an outlet cloth guide driving roller 35, wherein the traction cloth guide driving roller 32 and the outlet cloth guide driving roller 35 are mainly used for realizing the rapid discharging of the fabric 2c after the overedged fabric is completed, meanwhile, the swing arm 34 with a swing effect is ingeniously arranged between the traction cloth guide driving roller 32 and the outlet cloth guide driving roller 35, the swing effect on the fabric 2c after the overedged fabric is completed can be well realized, the tension-free discharging effect on the fabric 2c after the overedged fabric is completed is finally realized, and the problem that the product is deformed due to the tension when the high-elasticity fabric cannot automatically produce the material 2c after the overedged fabric is solved, and the subsequent processes cannot produce and produce bad products is.

In conclusion, the automatic double-side single-layer multi-layer fabric overedger disclosed by the invention realizes the automatic overedged effect on the double sides of the multi-layer fabric, ensures the overedged effect, obviously improves the overedged efficiency and the product quality and greatly reduces the production cost.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
