Abstract

The invention relates to an apparatus for producing TPU (thermoplastic polyurethane) leather. The apparatus comprises a TPU feeding device, a tension control device, a coating device and a pressing device. The tension control device is arranged between the TPU feeding device and the pressing device; the coating device comprises a heating wheel, and a scraper and a hot melt adhesive guide device arranged above the heating wheel, and the scraper is arranged at the downstream of the hot melt adhesive guide device; the hot melt adhesive guide device is connected with a first lift and the scraper is connected with a second lift; the pressing device is arranged at the downstream of the coating device. The components of the device according to the invention cooperate with each other to produce TPU leather with the thickness within the range of 0.1 to 5.0 mm and with the flatness of 0 to 0.1 mu m without curling and wrinkling. The yield is as high as 90% or more, the raw material loss is less than 10%, a production line can be shortened to 20 meters, and space is saved.

Description

technical field [0001] The invention relates to the technical field of polymer material processing, in particular to a device for producing TPU leather. Background technique [0002] Synthetic leather is a composite material that simulates the structure and performance of natural leather and can be used as a substitute for natural leather. Usually, the non-woven fabric is used to simulate the mesh layer, and the polyurethane coating is used to simulate the inner layer. The obtained synthetic leather has both front and back sides. It is very similar to leather and has a certain degree of air permeability. It is closer to natural leather than ordinary artificial leather. It is widely used in the manufacture of shoes, boots, bags and balls. At present, the traditional artificial leather manufacturing is divided into dry method and wet method. The wet method refers to mixing the raw material resin in water to make a solution, and then dipping the base cloth in the solution for r...
