Description

Technical Field

[0001] The utility model relates to the technical field of leather processing, in particular to a leather softening machine with a dust removal device. Background Art

[0002] Leather refers to animal skin that has been denatured and not easily rotted after physical and chemical processes such as dehairing and tanning.

[0003] In the process of making leather, the leather needs to be thrashed to make it softer and with clearer texture. In the process of thrashing the leather, the dust on the leather will also be knocked out, but some existing equipment will not handle the dust knocked out by the leather, which may easily lead to problems in the subsequent leather processing and affect the processing quality of the leather. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a leather softening machine with a dust removal device, which is used to solve the technical problem that some existing softening equipment cannot clean the dust on the leather, thus affecting the quality of subsequent leather processing.

[0006] A leather softening machine with a dust removal device, comprising:

[0007] Protective tube;

[0008] a first roller, the first roller being rotatably disposed in the protective cylinder;

[0009] a second roller, the second roller being disposed inside the first roller;

[0010] Two connecting plates, the two connecting plates are symmetrically fixed between the first roller and the second roller;

[0011] A plurality of force-bearing plates, wherein the plurality of force-bearing plates are fixedly arranged on the inner wall of the second drum;

[0013] The second discharge port is provided through the peripheral wall of the second drum, and the second discharge port is connected with the second drum and the protective drum.

[0014] Working principle:

[0015] Put the leather that needs to be softened into the second roller, rotate the first roller, the first roller drives the second roller to rotate through the connecting plate, and the second roller drives the leather inside to rotate. When the second roller rotates a certain angle, the leather falls under the action of its own gravity and falls on the force plate. When the leather is softened, the dust on the leather floats out, the dust leaves the second roller from the second discharge port and enters the first roller, and the dust leaves the first roller from the first discharge port and enters the protective cylinder.

[0017] Put the leather that needs to be softened into the second roller, rotate the first roller, the first roller drives the second roller to rotate through the connecting plate, and the second roller drives the internal leather to rotate. When the second roller rotates a certain angle, the leather falls under the action of its own gravity and falls on the force plate. The leather is softened under the action of the force plate. When the leather is softened, the dust on the leather floats out, the dust leaves the second roller from the second discharge port and enters the first roller, and the dust leaves the first roller from the first discharge port and enters the protective cylinder. The protective cylinder collects the dust on the leather, thereby reducing the dust attached to the leather and facilitating the subsequent processing of the leather.
