[0036] The utility model provides Figure 1-Figure 7 The leather dyeing drum shown includes a liquid separation base 1, which opens upward, and the left and right sides of the upper end of the liquid separation base 1 are fixedly connected to support columns 2, and a dyeing bucket 3 is rotatably connected to the upper side between the two support columns 2. An inlet and outlet port 4 is provided at the front end of the support column 2, and a stirring connecting disk 5 is rotatably connected to the inside of the left and right ends of the dyeing bucket 3. A plurality of stirring plates 6 are fixedly connected to the outside between the two stirring connecting disks 5, and the plurality of stirring plates 6 are fitted with the inner wall of the dyeing bucket 3 at one end away from the center of the dyeing bucket 3. A connecting rotor 7 is fixedly connected at the center of the left and right ends of the dyeing bucket 3, and is rotatably connected between the two support columns 2 through the connecting rotor 7. The center of the stirring connecting disk 5 on the left side is fixedly connected to a rotating column 12 at one end away from the stirring plate 6, and is rotatably connected to the inside of the dyeing bucket 3 through the rotating column 12. The stirring connecting disk on the right 5 is fixedly connected to the center of one end away from the stirring plate 6 with a stirring shaft 13, the stirring shaft 13 passes rightward through the center of the right end of the dyeing barrel 3 and the connecting rotor 7, and passes through the right end of the right support column 2. The left end of the stirring shaft 13 is connected to a stirring motor 14, and the two stirring connecting plates 5 and the multiple stirring plates 6 are rotatably connected to the stirring motor 14 through the stirring shaft 13. The stirring motor 14 is fixedly connected to the outside of the right support column 2. The dyeing liquid and leather are added to the dyeing barrel 3 through the inlet and outlet 4, and the stirring motor 14 is turned on. The stirring motor 14 drives the two stirring connecting plates 5 and the multiple stirring plates 6 to rotate inside the dyeing barrel 3 through the stirring shaft 13, thereby stirring the dyeing liquid and leather inside the dyeing barrel 3, so that the leather can be dyed quickly and evenly, thereby improving the dyeing efficiency and dyeing quality of the leather.

[0037] Preferably, the left end center of the connecting rotor 7 is fixedly connected to a limited swivel 8, and a limited tooth groove 9 is provided inside the front lower corner of the inner wall of the cylinder of the limiting swivel 8. The lower end of the limiting swivel 8 is internally connected to a limited gear 10 in a rolling manner. The limiting gear 10 and the limiting tooth groove 9 are meshed with each other.

After the leather dyeing is completed, the limiting motor 11 is turned on and the limiting The motor 11 drives the limiting gear 10 to mesh and roll with the limiting tooth groove 9 through the rotating shaft, thereby driving the limiting swivel 8 to rotate. The limiting swivel 8 drives the dyeing barrel 3 to rotate by connecting the rotating head 7. Since the limiting tooth groove 9 is arranged in a ninety-degree fan shape with the central axis of the limiting swivel 8, when the front end of the limiting tooth groove 9 rotates to the lower end, it will stop rotating and rotate the inlet and outlet 4 to the lower end.

After the leather is separated, the separation trough 15 can be pulled forward by the pull handle 17, and slide on the upper end of the liquid separation base 1 through the limit sliders 18 and the limit slides 19 on both sides, thereby pulling the separation trough 15 out of the lower end of the dyeing barrel 3, making it easier to take the leather out of the separation trough 15. At the same time, the dyeing liquid entering the interior of the liquid separation base 1 can be discharged from the interior of the liquid separation base 1 through the liquid guide tube 20, which is more convenient for handling the dyeing liquid.
