Abstract

The invention relates to the technical field of spraying devices, and discloses a double-edged liquid knife and a liquid spraying device. The double-edged liquid knife includes a first liquid knife plate, a second liquid knife plate and a third liquid knife plate. The first liquid knife plate is provided with a first distribution channel, and the second liquid knife plate is opposite to the first liquid knife plate The second liquid knife plate is provided with a second distribution channel, and both the first distribution channel and the second distribution channel are communicated with the liquid inlet chamber. There are two third liquid knife plates. One of the third liquid knife plates is connected with the first liquid knife plate to form a first nozzle channel, and the other third liquid knife plate is connected with the second liquid knife plate in an opposite cover. The second spout channel is formed, and the first spout channel and the second spout channel are both bent channels, which can ensure the pressure of the liquid outlet is stable, so that the waterfall formed by the liquid knife spray is not easy to bifurcate, and the spraying is more uniform, which greatly improves the product quality.

Description

technical field [0001] The invention relates to the technical field of spraying devices, in particular to a double-edged liquid knife and a liquid spraying device. Background technique [0002] In the flat panel display industry, AMOLED industry, printed circuit board industry, photovoltaic industry and other industries, the liquid knife is a core component in the entire process, and is mainly used to spray waterfalls with uniform and equal thickness. Among them, liquid jetting devices with liquid knives are widely used in cleaning machines, stripping machines, etching machines, coating machines and developing machines. [0003] like figure 1 Shown is the double-edged liquid knife currently on the market, which is only formed by splicing the traditional single-edged liquid knife structure. , which takes up a lot of space, which is not conducive to installation and debugging. On the other hand, the internal structure of the liquid knife is single, and the waterfall formed ...
