Problems solved by technology

[0003] In some cases, for example, due to the humid winter climate in the south, the bottom of the coating liquid pan above the strip is prone to condense dew and drip on the surface of the strip, resulting in defects in the quality of the strip, resulting in the horizontal double-sided roller coating of several units The machine cannot be used normally in winter, which seriously limits the production capacity

Embodiment 1

[0023] like figure 1 and image 3 , the embodiment of the present invention provides a liquid coating plate of a roller coater, including a plate body 200, which is mainly used to hold paint, and is convenient for the coating head to dip in the paint; the plate body 200 is a conventional equipment in the field, The specific structure will not be repeated this time. The bottom of the tray body 200 is provided with a pneumatic anti-condensation mechanism 100 for improving air circulation around the bottom of the tray. The pneumatic anti-condensation mechanism 100 includes an air blowing unit and an air supply unit connected to the blowing unit. The air blowing direction of the air blowing unit is toward the outer surface of the bottom of the tray and / or toward the space below the tray body 200 .

[0024] The liquid coating pan provided in this embodiment, by setting an air blowing unit at the bottom of the pan, promotes the air circulation around the bottom of the pan, which c...

Embodiment 2

[0035] like image 3, the embodiment of the present invention provides a kind of roller coating machine, comprises upper coating head 300 and lower coating head (illustrated, not labeled), and described upper coating head 300 is equipped with upper coating liquid pan, and described lower coating head The layer head is equipped with a lower coating liquid pan, and the upper coating liquid pan adopts the coating liquid pan of the roller coater provided in the first embodiment above. Of course, the bottom coating liquid tray can also choose whether to configure the above-mentioned pneumatic anti-condensation mechanism 100 according to specific conditions.

Abstract

The invention relates to a liquid applying disc of a roll coater and the roll coater adopting the liquid applying disc. The liquid applying disc comprises a disc body, the bottom of the disc body is provided with a pneumatic anti-condensation mechanism used for improving the air ventilation condition of the periphery of the disc bottom, the pneumatic anti-condensation mechanism comprises an air blowing unit and an air supplying unit connected with the air blowing unit, and the air blowing direction of the air blowing unit faces the outer surface of the disc bottom and / or faces the space underthe disc body. According to the liquid applying disc and the roll coater, the air blowing unit is arranged at the disc bottom of the liquid applying disc, air around the disc bottom is promoted to circulate, damp air can be prevented from being condensed on the metal surface of the liquid applying disc, the condition that dew condensed at the bottom of the liquid applying disc drops on the strip steel surface to cause product quality defects is prevented, and the working stability of the roll coater is guaranteed; and the pneumatic anti-condensation mechanism is adopted, energy conservation and environment protection are achieved, the working stability is high, the sustainability is good, noise is low, the service life is long, and the liquid applying disc and the roll coater are suitablefor new construction of a roll coater unit and transformation of an existing roll coater unit.

Description

technical field [0001] The invention belongs to the technical field of cold rolling, and in particular relates to a liquid coating pan of a roll coater and a roll coater using the liquid coating pan. Background technique [0002] Due to the advantages of high film thickness control precision and large adaptability of coating liquid viscosity, roll coaters are widely used in cold-rolled strip processing units such as color coating, galvanizing, and silicon steel coating. Due to the small footprint, the horizontal double-sided roller coater is used in many units that run horizontally on the strip, that is, there are two coating heads arranged on a single set of roller coater, the upper coating head is located above the strip, and the coating strip Steel upper surface; the lower coating head is located below the strip and coats the lower surface of the strip; each coating head has its own applicator pan for dipping the coating. [0003] In some cases, for example, due to the h...
