Feeding system of film transfer sizing machine

Technical Field

The utility model relates to a size press equipment, more specifically the saying so, it relates to a membrane shifts sizing press's feeding system.

Background

The working principle of the film transfer sizing machine is that a uniform starch sizing material film is coated on the surface of a sizing roller through the metering of a metering rod, and then the uniform starch sizing material film is moved to a paper web in a transfer nip, so that the physical strength and the surface smoothness of the paper web are improved.

The metering rod is a metal rod with grooves on the surface, is a quick-wear part and needs to be replaced frequently. This is because metering sticks are prone to "stick out" and "wear". When the groove on the surface of the metering rod is blocked by glue, impurities and the like, the metering rod is called as a 'paste rod'; when the grooves on the surface of the metering rod become shallow, it is indicated that the metering rod has "worn out". At this point, a new metering rod needs to be immediately replaced. The measuring rod is frequently replaced, on one hand, the cost of the measuring rod can be directly measured, and during the replacement of the measuring rod, paper made by the paper is all unqualified products and needs to be re-made by returning all the paper to the furnace, so that huge waste is caused.
