Leather softening device

Abstract

The invention discloses a leather softening device. The leather softening device comprises two side frames, an outer barrel, an inner rotating drum, two or more support seats, wheels and wheel supports; rotating shafts at two ends of the inner rotating drum are respectively sleeved with the top ends of the side frames, arranged side by side, through bearing components; the rotating shaft at one end of the inner rotating drum is connected to a motor through a synchronous belt, and is used for driving the inner rotating drum to rotate; the cross section of the inner rotating drum is polygonal; the outer barrel is arranged outside the inner rotating drum; a gap is formed between the outer barrel and the inner rotating drum; the support seats are arranged on the inner wall of the outer barrelside by side; four or more wheels are evenly distributed on each support seat and opposite to the outer wall of the inner rotating drum, and the wheels are rotatably fixed to the outer wall of the inner rotating drum through the wheel supports. The leather softening device has the advantages that a support structure is arranged on the outer wall of the inner rotating drum, and accordingly, the stability is improved, and the service life is prolonged; meanwhile, through the design of an exhaust structure, hot air is exhausted through an exhaust pipe, so that sticky leather caused by the ultrahigh internal temperature of the inner rotating drum is avoided.

Description

technical field [0001] The invention belongs to the technical field of leather processing, and in particular relates to a leather softening device. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. [0003] In the existing leather processing process, it includes a softening process, which adopts a softening drum for processing. At present, the softening drum generally includes two types: circular drum and octagonal drum. The cross-section of the shell of the circular drum is circular; Octagonal, which can increase the leather load and improve the breaking strength, so that the softness, fullness and elasticity of the processed leather are further improved. However, it i...

Problems solved by technology

However, it is difficult to install bearing support in the middle section of the octagonal drum. Only the two ends are stressed, and the stability is poor during rotation, which will affect the service life.
