Description
Technical field
The invention belongs to leather production equipment technical field, it is related to the dyestuff cyclic system on a kind of leather double coater
System.
Background technology
The master operation of the preparatory stage of leather in process of production has：Immersion, fleshing, depilation, liming, degreasing, softening,
Pickling；Have in the master operation in tanning stage：Pre-tanning, main tanning and retanning；Have in the master operation of fin-ishing stages：Cut open layer, cut
Even, neutralization, dyeing, stuffing, drying, do soft, open and flat, buffing, covering with paint, embossing etc..
Wherein, dyeing course is of crucial importance, and leather coloring effect directly determines the quality and durability of leather, however, existing
Some leather coloring technique, is suppressed leather using steel rider, and by dye mixture dip-coating on leather, leather passes through steel rider
Compacting after, due to unbalance stress, pressure changes at any time, causes dye mixture skewness after leather coloring, although skin
Leather dyeing course is not the color after leather shaping, but dyeing is uneven to the cortex hardness of leather, tensile property and other ginsengs
Number all has an impact, and situations such as deformation, bulge subsequently easily occurs in use in leathercraft.
Between this, the application provides one kind and dyes more uniform, the more prominent roll coater of dip-dye effect.
The content of the invention
The purpose of the present invention be for existing technology exist above mentioned problem there is provided on a kind of leather double coater
The dyestuff circulatory system, the technical problems to be solved by the invention are how to save dyestuff, and dyestuff processing Posterior circle is utilized.
The purpose of the present invention can be realized by following technical proposal：A kind of dyestuff cyclic system on leather double coater
System, it is characterised in that roll coater, which includes the sleeve one of base, arc one, arc two, one side with end cap, one side, to be had
The sleeve two of end cap and rotating shaft, the arc one and arc two are fixedly linked with the sleeve one and sleeve two, described
Arc one is identical with the curvature of arc two and can form a circular dyeing tube, the arc one and arc two
