Wherein the reference numbers are: the cloth feeding device comprises a overedger base 1, a cloth feeding tooth rack 2, a sliding groove 3, a circular shaft section 4, an adjusting shaft, a sliding block 8, a through hole 9, an adjusting rod 10, a handle part 11, an indicating part 12, a gear display panel 13, a fixing bolt 14, a fixing hole 15, a clamping ring 16, a limiting notch 17, a check ring 18, a positioning head 19, a positioning plane 20, a positioning part 21 and a threaded hole 22.
The utility model discloses a work feed retainer adjusting device, including overedged frame 1, be equipped with the cavity of installation work feed retainer 2 in the front portion of overedged frame 1. The two cloth feeding tooth racks 2 are arranged side by side, the tail parts of the two cloth feeding tooth racks are respectively provided with a sliding groove 3, and a sliding block 8 used for adjusting the working height and the inclination angle of the cloth feeding tooth racks 2 is arranged in the sliding groove 3. The front part of the overedger base 1 is provided with an adjusting shaft which is provided with an eccentric section 5 and a circular shaft section 4 which are connected integrally. The eccentric section 5 of the adjusting shaft is rotatably connected with the sliding block 8, and the height of the working position of the sliding block 8 can be changed when the adjusting shaft rotates, so that the height and the inclination angle of the cloth feeding tooth frame 2 are adjusted.
Two sides of the sliding block 8 are respectively provided with a retainer ring 18, and the two retainer rings 18 are locked on the eccentric shaft 5. The stop ring 18 is used to fix the position of the slide 8 on the eccentric shaft 5 and to prevent the slide 8 from being shifted out of the slide groove 3 by vibrations.
