Description
Technical Field
[0001] The utility model belongs to the technical field of leather processing equipment, and particularly relates to a device for preparing high-fastness leather. Background Art
[0002] Leather and fur are usually produced from large and small raw hides through multiple steps. After the preparatory work in the liming workshop, such as dehairing, fleshing, deliming and softening, typical processes consist of tanning, retanning, dyeing, fatliquoring and finishing, and each operation can be further subdivided.
[0003] Retanning can be understood as the post-treatment of pre-tanned leather in order to optimize color, uniformity, softness, fullness and water properties (hydrophobic properties) and to fix tanning agents. After the post-treatment, the commonly used anionic post-treatment composition is fixed with a cationic polymer; in particular, an aqueous solution or dispersion of a tanning agent / retanning agent or a dye solution is usually used for tanning, retanning and dyeing in a tanning drum;
[0004] The disadvantage of this post-treatment in a tanning drum is that, due to the leather materials piling up in the dye vat, the dyes or oils cannot be evenly fixed on the leather in the form of stirring, so the modification target of the leather cannot be achieved. Summary of the Invention

[0006] The above technical problems of the utility model are mainly solved by the following technical solutions: A device for preparing high-fastness leather, including an installation bracket, the installation bracket includes two side plates, four sprockets are provided on the inner side surfaces of the two side plates, the four sprockets are respectively arranged at the four corners of the side plates, a deflector wheel is arranged between the two rear sprockets, a transmission chain is wound around the four sprockets and the deflector wheel, fixing clips are equidistantly arranged on the transmission chain, an arc-shaped cloth support plate is connected between the two side plates corresponding to the two front sprockets and between the two side plates corresponding to the deflector wheel, a water permeable groove is arranged at the middle position of the arc-shaped cloth support plate, a water spraying assembly is arranged between the two side plates, the water spraying assembly includes a main pipe, the main pipe includes three horizontal conveying parts, the heights of the three horizontal conveying parts are equal to the heights of the three arc-shaped cloth support plates, a plurality of pipe interfaces are equidistantly arrayed on the front and rear sides of the horizontal conveying part, and a nozzle is connected to the pipe interface facing the arc-shaped cloth support plate.
[0007] Preferably, the outlet of the nozzle faces the water permeable groove of the arc-shaped cloth support plate.
[0008] Preferably, the pipe interfaces on the side away from the arc-shaped cloth support plate are sealed.
[0009] Preferably, connecting plates are connected between the front and rear ends of the two side plates.
[0010] The beneficial effects of the present utility model are as follows: By setting a sprocket and a transmission chain, the leather material is fixed on the transmission chain through a fixing clip, and the rotation of the transmission chain drives the leather material to rotate and move in the dye vat, so that it can regularly soak up and down in the aqueous solution or dispersion or dye solution of the tanning agent / retanning agent in sequence, thereby enabling the dye or grease to be evenly attached and fixed on the surface of the leather material; with the setting of the water spraying assembly, the aqueous solution or dispersion or dye solution of the tanning agent / retanning agent can be impacted on the surface of the leather material through the nozzle, thereby accelerating the time for the aqueous solution or dispersion or dye solution of the tanning agent / retanning agent to adhere to the surface of the leather material and increasing the efficiency of the dyeing treatment.
