High-efficiency leather making equipment for segmented ironing

Abstract

The invention discloses a piece of high-efficiency leather making equipment for segmented ironing. The equipment comprises a heating roller and a pressing roller for heating or pressing the leather, and also comprises a jet pipe and an electric heater. The jet pipe, whose wall are provided with several jet holes, communicates with a supersonic water atomizer; intervals between the centers of the jet holes are identical; the area of the jet holes near the center of the jet pipe is large than the area of the jet holes near the two ends of the jet pipe and gradually varies; when a piece of fabric passes through lower part of the jet holes, the two ends of the fabric contact the atomized vapor with a higher humidity; The electric heater, installed on a frame and heats a roller ring, is composed of an electric heating wire, an insulation bracket and a heat collecting shield; the electric heating wire is wound around the insulation bracket, wherein the electric heating wire near the two ends of the roller ring is densely wound around the insulation bracket, while the electric heating wire near the center of the roller ring is sparsely wound around the insulation bracket; the spacing gradually varies; so that two ends of the roller ring acquire more heat than the center, the two ends of the roller ring has a higher temperature, the temperature varies gradually from two ends to the center of the roller ring. The leather making equipment for segmented ironing has advantages of heat, water and electricity conservation, high temperature, humidity and pressure shaping, and accurate and good control.

Description

technical field [0001] The invention relates to a device for ironing corrugated cloth during synthetic leather processing. Background technique [0002] During the processing of synthetic leather, the cloth is sent to the coating machine, and the heated leather slurry is coated on the cloth to form synthetic leather. In the prior art, in order to prevent the cloth from being wrinkled and uneven, there is a process of pressing the cloth before coating 1. In the process of heating and removing wrinkles, since the wrinkled cloth has certain elasticity, when the pressure and temperature are removed, it will return to the wrinkled state to some extent. In order to further improve the wrinkle removal effect, the humidity can be increased, that is, after adding Increase the humidification process before pressing and heating, and remove wrinkles through high temperature, high humidity, and high pressure, and the wrinkle removal effect will be significantly improved. However, there...

[0002] During the processing of synthetic leather, the cloth is sent to the coating machine, and the heated leather slurry is coated on the cloth to form synthetic leather. In the prior art, in order to prevent the cloth from being wrinkled and uneven, there is a process of pressing the cloth before coating 1. In the process of heating and removing wrinkles, since the wrinkled cloth has certain elasticity, when the pressure and temperature are removed, it will return to the wrinkled state to some extent. In order to further improve the wrinkle removal effect, the humidity can be increased, that is, after adding Increase the humidification process before pressing and heating, and remove wrinkles through high temperature, high humidity, and high pressure, and the wrinkle removal effect will be significantly improved. However, there are two sides to things. High humidity will evaporate after high temperature, and steam will take away a lot of heat, thus increasing energy. When the cloth is transported from the cloth factory to the synthetic leather factory, the two ends
