Abstract
Description
Technical Field
[0001] The utility model generally relates to the field of leather processing equipment, and in particular to a leather conveying device. Background Art
[0002] Plain leather is thin and soft. Compared with embossed leather, plain leather is gradually gaining market share. Plain leather needs to be sprayed twice on its surface during the process of processing from semi-finished products to finished products to obtain good physical and chemical properties. Both spraying processes are achieved through the connection between the spray room and the drying tunnel.
[0003] In the prior art, leather is conveyed through a spray chamber and a drying tunnel by a nylon line conveying mechanism. Since the texture of plain leather is soft and smooth, after being conveyed by the nylon line through the drying tunnel for drying, obvious "line marks" will be left on the surface of the leather. The "line marks" are caused by the reaction pressure of the conveying nylon line while the temperature of the internal fiber tissue rises and the water evaporates during the drying process in the drying tunnel. This causes quality defects in the product. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a leather conveying device that improves product quality.

[0007] The second conveying mechanism comprises a conveying net, which is used to support and transport the leather, and the conveying net is partially located in the drying tunnel;
[0008] The transition mechanism is located in the drying tunnel, and includes a fixing member, a first fixing plate and a second fixing plate. The fixing member is fixedly connected with a plurality of arc-shaped guide members arranged at intervals. The first fixing plate and the second fixing plate are respectively fixed to the main frame. A first bolt passes through the first fixing plate and is screwed to one end of the fixing member, and a second bolt passes through the second fixing plate and is screwed to one end of the fixing member. The guide member is exposed from the gap between the nylon lines.
[0009] According to the technical solution provided in the embodiment of the present application, nylon wire is used to transmit the leather through the spray chamber, and the leather on the nylon wire is transferred to the conveying net through a transition mechanism.
