Abstract: The present invention discloses a slit nozzle cleaning device, the slit nozzle cleaning device comprises a scraper for cleaning the slit nozzle and an auxiliary inserting means, wherein the auxiliary inserting means is configured to guide the scraper into the slit nozzle. With the aid of the auxiliary inserting means, the scraper can enter the slit nozzle smoothly and precisely without the risk of breaking.

Abstract: The present invention provides a spray nozzle, configured with left and right halves, at least one of the left and right halves being defined with a mating surface in which a recess defining width of a linear opening of the nozzle is defined, each end of the nozzle being mounted with fenders jointly define the linear opening of the nozzle along with the recess, wherein the mating surface in which the recess is defined further includes with a N number of partitions dividing the recess into a N+1 number of individual ejectors, wherein N is a positive integer. The present invention is to divide a single mouth of a spray nozzle of larger dimension into a plurality of individual ejectors with smaller dimension. During the acceleration or reduction of the spray nozzle, each individual ejector will deliver a homogeneous and even quantity of working liquid at central and end portions.
