Embodiment Construction

[0030] Such as figure 1 As shown, the drum assembly in the genuine leather tanning device, the leather tanning device includes a frame 1, an upper drum 2 and a lower drum 3, the upper drum 2 and the lower drum 3 are arranged in parallel and both are axially fixed on the above frame 1, a pressing gap is formed between the upper cylinder 2 and the lower cylinder 3 for the leather raw material to be pressed through. The two ends of the lower cylinder 3 have protruding limit edges 4, and the above limit edges 4 abut against On the upper roller 2 and between the upper roller 2, the lower roller 3 and the limit edge 4, a pressing part matching the leather material is formed. The outer side of the upper roller 2 is covered with a cylindrical contact sleeve 5. The above limit edge There is an elastic mechanism between 4 and the lower roller 3, and the above-mentioned limit edge 4 has a tendency to abut against the contact sleeve 5 under the action of the elastic mechanism.

Abstract

The invention provides a roller module in a leather tanning device and belongs to the technical field of machinery. The roller module solves the problem that in the prior art, the stability is poor. The roller module in the leather tanning device comprises a rack, an upper roller and a lower roller. The upper roller and the lower roller are arranged in parallel and axially and fixedly connected to the rack. A pressing gap for a leather raw material to pass through in a pressed manner is formed between the upper roller and the lower roller. Protruding limiting edges are arranged at the positions of the two ends of the lower roller, the limiting edges abut against the upper roller, and a pressing part matched with the leather raw material is formed among the upper roller, the lower roller and the limiting edges. The outer side of the upper roller is sleeved with a cylindrical contact sleeve, elastic mechanisms are arranged between the limiting edges and the lower roller, and under the action of the elastic mechanisms, the limiting edges trend to abut against the contact sleeve. The roller module in the leather tanning device is high.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a drum assembly in a leather tanning device. Background technique [0002] Leather tanning refers to the production of animal hides that are processed by physical and chemical methods such as depilation and tanning, and then painted and finished to make leather with properties such as non-perishable, flexible, and breathable. [0003] One of the processes is to squeeze it through the upper and lower adjacent rollers to obtain the required leather physical properties. [0004] But, existing tanning device all is to directly adopt two metal cylinders to squeeze it. At the same time, in order to limit the position of the leather raw material, a retaining edge is provided at both ends of one of the rollers. During use, the retaining edge may come into contact with one of the rollers, and the friction will cause premature damage to the roller, reducing the service life and increasing...
