Description
Technical field
The present invention relates to corrugated paper production technical fields, and in particular to a kind of preheating with semicircle periphery heating preheating cylinder
Device.
Background technique
Corrugated paper is cardboard common in a kind of life, is commonly used to production packing box, packing case etc..Corrugated paper is one kind three
Weight combination board is by sheet lining and the plate object being bonded by the waveform corrugated paper that corrugated roller processing is formed, corrugation
The invention and application of paper have more than 100 years history histories, and at low cost, light weight, processing is easy, intensity is big, printing adaptability sample is excellent
It is good, storage convenient in carrying the advantages that, 80% or more corrugated paper can be used as food or number by reclaiming, corrugated paper
The packaging of code product, relatively environment-friendly, use is relatively broad.
In the production process of corrugated paper, need to use preheating device to carry out pre- thermal technology to the core paper and facial tissue of corrugated paper
Make, there are two main effects: first is that playing pre- heat effect, glue being made to be easier to bond；Contain second is that playing and reducing paper pulp moisture
The effect of amount.
The core component of preheating device used is exactly preheating cylinder when existing corrugated paper produces, and preheating cylinder is mostly closed
Hollow cylinder cylinder body, by being passed through steam to cylinder interior, using steam again to inboard wall of cylinder block heat, heat by inner wall conduct to
Inner wall will finally be located at the raw material cardboard on outer wall again and preheat.The preheating cylinder preheating speed of above structure is slower, needs steam
