Plasticizing drying oven for artificial leather synthetic leather production line

Abstract

The invention provides a plasticizing drying oven for an artificial leather synthetic leather production line. The plasticizing drying oven comprises an oven body, wherein the oven body is composed of a framework made of profile steel and a heat-preservation board arranged outside the framework; the heat-preservation board is internally filled with a pressed and molded aluminum silicate fiber block; a heat exchanger and a heat conveying fan located on one side of the heat exchanger are arranged at the bottom of the oven body; an air inlet of the heat conveying fan is connected with the heat exchanger by an air suction cover; an air outlet of the heat conveying fan is connected with a vertical air conveying pipe; the upper end of the vertical air conveying pipe is connected with a horizontal air conveying pipe located in the upper part of the oven body; the two ends of the horizontal air conveying pipe are blocked; the lower surface of the horizontal air conveying pipe is provided with an air nozzle which sprays hot air downwards along the length direction; an air exhausting pipe is arranged at the top of the oven body. The plasticizing drying oven for the artificial leather synthetic leather production line is reasonable in design and simple and compact in structure; the heat insulation effect of the oven body is good; the heat exchanging efficiency of the heat exchanger is high, the air amount of the heat conveying fan is great and the noise is low; the whole set of the air exhausting pipe only needs to be provided with an air exhausting machine on a waste gas purification device, so that the electric energy is saved and the cost is sufficiently reduced.

Description

technical field [0001] The invention belongs to the technical field of leather production, in particular to a plasticizing oven for a production line of artificial leather and synthetic leather. Background technique [0002] The oven is a method for manufacturing PU / PVC artificial leather, PU synthetic leather, PVC floor, PVC three-proof tarpaulin, PVC anti-slip mat, PVC fabric coating, laminated leather (splitting skin transfer film leather or Erlang skin), latex sponge, etc. Indispensable equipment for products. The frame of the existing oven adopts section steel to be integrally manufactured and transported as a whole. The cavity of the insulation board is filled with aluminum silicate fiber cotton. The fiber cotton is easy to cause volume shrinkage after vibration. After shrinkage, there will be space in the cavity of the insulation board, which will affect the insulation effect. [0003] The heat exchanger (radiator) is the heart of the heat source of the oven. The ma...

AI Technical Summary

Problems solved by technology

Axial flow fan has a large air volume and high wind pressure, which will generate pressure on the surface of the foamed product, simulate foaming, prolong the foaming time, and reduce production efficiency

Ordinary centrifugal fans also have the problem of large air volume and high wind pressure and high noise

[0005] In addition, each heating zone of the oven is equipped with an exhaust pipe and an exhaust fan, which not only has high manufacturing costs, but also wastes more electric energy, resulting in a corresponding increase in use costs.
