Background

The paper machine sizing machine mostly adopts a soaking type sizing machine and a film transfer sizing machine, the soaking type sizing is to press two rollers which are arranged in an inclined way together, glue solution forms a glue pool above a press area, and a paper sheet passes through the press area to adsorb certain glue material, thereby completing the sizing process; film transfer size presses are metered by a metering bar and the surface of a transfer roll is coated with a uniform thin film of size and then transferred to the paper web in a transfer nip. Compared with the traditional soaking type sizing machine, the film transfer has better running performance, excellent application precision and operation safety, can finish sizing under the condition of low sizing amount and ensures the coverage and uniformity. The metering rod is used as an important spare part of the film transfer sizing machine, and has a unique groove metering mode, and the sizing amount can be realized by adjusting the solid content of sizing materials and also adjusting the pressure between rollers, the speed ratio and the loading pressure; the metering rod is used as a consumable product, the service cycle of the metering rod directly depends on the running parameters of the paper machine, including vehicle speed, raw materials, sizing materials, loading pressure, lubrication and the like, and the metering rod in the existing sizing machine is easy to damage and has a short service life.
