压力施胶机设计+CAD图纸
压力施胶机有两根辊，上辊和下辊夹角为30°。为了方便引纸，通过差动螺旋机构和底部的气垫装置调节两辊的间隙和不同的线压，以达到给不同纸张，不同胶液，不同线压要求的施胶过程。两辊有两个电机带动，配以液压系统，将胶液箱中的胶液通过喷头喷出，调节流量大小进行施胶量的调节，以达到最佳施胶效果。

Pressure sizing machine design
Abstract:Physical properties of coating surface sizing is usually to prevent infiltration of liquid, let the paper obtain better surface properties and improved pages, improve the properties of base paper is the most efficient means. Through the surface applied glue machine emulsion glue continuous, uniform, and stable coating on the surface of the paper, after infiltration, infiltration and extrusion, a series of physical action, in the paper surface to form a thin layer of waterproof layer, greatly improve the water absorbency of the paper and also in glue improve between fibers with the tightness of paper strength and, which can improve the paper lateral ring crush index, longitudinal crack breaking length and other technical indicators.
There are two rollers in the pressure sizing machine, the angle between the upper and the lower rollers is 30.. In order to facilitate the cited paper, the differential screw mechanism and bottom air cushion device regulation two roll gaps and different line pressure, in order to give different paper and different adhesive, different line pressure requirements applied glue process. Two roller two motor drive, with the hydraulic system, glue liquid in the plastic box through the nozzle, adjust the flow rate of sizing, to achieve the best sizing effect.
Key Words:Sizing machine, surface uniform sizing, line pressure, two roll, convexity
