[0026] like Figure 1 , Figure 2 and Figure 5 As shown, the leather octagonal softening drum provided in this embodiment includes a support seat 10, a rotating drum 11 is rotatably installed inside the support seat 10, and transmission gear rings 12 are arranged at both ends of the rotating drum 11, a rotating shaft 19 is rotatably installed at the lower end inside the support seat 10, and transmission gears 25 are arranged at both ends of the rotating shaft 19, and the transmission gear 25 is meshed with the transmission gear ring 12, a driving motor 13 is arranged on one side of the support seat 10, and the driving motor 13 is transmission-connected with the rotating shaft 19, an octagonal grille tube 15 is arranged inside the rotating drum 11, a discharge pipe 14 is arranged in the middle of one side of the rotating drum 11, and one end of the discharge pipe 14 extends to the outside of the support seat 10, and bumps 16 are arranged on both sides of the inner wall of the octagonal grille tube 15, and retaining bars 17 are evenly arranged on both sides of the inner wall of the octagonal grille tube 15;

[0027] In this embodiment, the leather can be put into the interior of the rotating drum 11 through the discharge pipe 14, and the driving motor 13 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the rotating drum 11 to rotate through the transmission gear 25 and the transmission gear ring 12. The rotating drum 11 drives the octagonal grille tube 15 to rotate, so that the leather is rotated and beaten inside the octagonal grille tube 15. Under the action of the protrusion 16, the leather can be well beaten. Under the action of the baffle 17, it is easy to drive the leather to rotate, thereby enhancing the softening effect.

[0028] like Figure 1 and Figure 2 As shown, the leather octagonal softening drum provided in the present embodiment has an auxiliary material unloading structure at the lower end of the support seat 10, and the auxiliary material unloading structure includes a support column 2, and the support column 2 has two, which are movably mounted on both sides of the lower end of the support seat 10, and a base 1 is fixedly mounted on the lower end of the support column 2, and a fixing bar 3 and a support frame 8 are fixedly mounted on the upper end of the base 1, and two adjusting screws 4 that are mutually transmission-connected are rotatably mounted between the fixing bar 3 and the support frame 8, and the surfaces of the two adjusting screws 4 are movably sleeved with adjusting screw sleeves 5, and a movable support rod 6 is movably mounted on one side of the adjusting screw sleeve 5, and the movable support rod 6 is movably connected to the lower end of the support seat 10, and a driver 7 is fixedly mounted on one side of the fixing bar 3, and the output end of the driver 7 is transmission-connected to one of the adjusting screws 4, and a material receiving box 9 is arranged on the upper end of the support frame 8;

[0029] In this embodiment, when the leather is discharged, the driver 7 drives one of the adjusting screws 4 to rotate, and the two adjusting screws 4 rotate synchronously under the action of the transmission sprocket and the transmission chain. The adjusting screw sleeve 5 moves along the adjusting screw 4 under the action of the thread, and the adjusting screw sleeve 5 drives one end of the movable support rod 6 to move. The other end of the movable support rod 6 drives the support seat 10 to rotate with the support column 2 as the support point, so that the rotating drum 11 is tilted, and the leather inside the rotating drum 11 can fall through the discharge pipe 14 and fall into the inside of the receiving box 9, which is convenient for the rapid discharge of the leather.

[0030] like Figure 3 and Figure 4 As shown, the leather octagonal softening drum provided in this embodiment has a dust exhaust structure at the lower end of the drum 11, and the dust exhaust structure includes a dust exhaust pipe 18, which is arranged on the surface of the drum 11, and the dust exhaust pipe 18 is close to the discharge pipe 14.

[0031] In the present embodiment, when the leather octagonal grille tube 15 is rotating and being beaten, impurities adhered to the surface of the leather can pass through the octagonal grille tube 15 and fall into the interior of the rotating drum 11. When the driving motor 13 drives the rotating shaft 19 to rotate, the rotating shaft 19 can drive the cam 20 to rotate. When the longer end of the cam 20 contacts the connecting seat 23, the connecting seat 23 moves upward, and the connecting seat 23 drives the knocking rod 22 to move upward to knock the surface of the rotating drum 11. When the longer end of the cam 20 is separated from the connecting seat 23, the knocking rod 22 and the connecting seat 23 return to their original positions downward and are separated from the surface of the rotating drum 11. The rotating drum 11 can be repeatedly knocked to cause the rotating drum 11 to vibrate, thereby preventing impurities inside the rotating drum 11 from adhering to the inner walls of the rotating drum 11 and the octagonal grille tube 15, affecting dust removal. When discharging the material, the dust removal pipe 18 moves downward, and the impurities on the inner wall of the rotating drum 11 can be discharged through the dust removal pipe 18, thereby preventing impurities from remaining inside the rotating drum 11 and affecting the processing of the leather.
