The invention discloses a
meniscus gelatinizing device for the single-sided gelatinizing of steel band tapes, which belongs to the field of steel band tape gelatinizing devices for
grating ruler manufacturing. The device comprises a driven steel band plate, two steel band plate brackets, a steel band tape horizontal positioning device, a slit plating rod, a glue conveying
pipe, a delivery pump, a glue container, a glue solution solidifying device, a driving steel band plate, a vacuumizing
system and a driving device, wherein the slit plating rod is located between the driven steel band plate and the driving steel band plate and arranged below the motion plane of a steel band; and the two ends of the delivery pump are connected with the glue conveying
pipe, and the glue container is connected with the slit plating rod through the glue conveying
pipe and the delivery pump. By using the device disclosed by the invention, a
meniscus gelatinizing method can be applied to a one-time gelatinizing process of steel band tapes belonging to a wide and large-surface flexible material, the
utilization rate and
recovery rate of a glue solution for
film coating are both relatively high, and the thickness of a coated film formed by the glue solution can be precisely controlled, and uniform; and in addition, the glue solution for
film coating required by the gelatinizing device is easy to prepare, and therefore, the gelatinizing device can well satisfy the gelatinizing requirements of the coated films of the steel band tapes.
