A strip hole is provided on the top of the support frame 3, and the telescopic connecting pipe is located in the strip hole. A stretching assembly is provided at the bottom of the second slider 6; the stretching assembly includes a rotating frame 8 fixedly connected to the bottom of the second slider 6, and the lower end of the rotating frame 8 is rotatably connected to a limited sliding rod 9, and a stretching roller 10 is slidably connected to the limited sliding rod 9. The limited sliding rod 9 is provided with a plurality of limiting protrusions, and the rotation stability of the stretching roller 10 can be ensured by the limiting effect of the limiting protrusions. A tension spring 11 is fixedly connected between the stretching roller 10 and the end of the limited sliding rod 9;

[0025] By pulling the stretching roller 10 to slide toward the middle position of the placement platform 2, the stretching spring 11 on the limit sliding rod 9 is gradually in an extended state, the sheepskin is passed through the stretching roller 10 and spread flat on the placement platform 2, and the sheepskin is fully fixed by controlling a plurality of electric push rods 16, and then the servo motor 15 is started, and the servo motor 15 drives the moving screw 4 to rotate, so that the first slider 5 and the second slider 6 on the moving screw 4 start to move synchronously, and the sheepskin can be limed by the lime sprayer 7 at the bottom of the first slider 5.

At the same time, the stretching roller 10 rotates relative to the sheepskin by friction, and the elastic force of the stretching spring 11 pulls the stretching roller 10 to move toward the outside of the placement platform 2, so that the stretching roller 10 can elastically stretch the side of the sheepskin when rotating, so as to keep the sheepskin in a stretched state before lime coating, so that the lime coating treatment of the sheepskin is more uniform and sufficient;
