Abstract

The invention relates to the technical field of spraying devices, and discloses a double-edge liquid cutter and a liquid spraying device. The double-edge liquid cutter comprises a first liquid cutter plate, a second liquid cutter plate and a third liquid cutter plate, a first flow dividing channel is arranged on the first liquid cutter plate, the second liquid cutter plate and the first liquid cutter plate are oppositely connected in a covering mode and matched to form a liquid inlet cavity, a second flow dividing channel is arranged on the second liquid cutter plate, and the first flow dividing channel and the second flow dividing channel are both communicated with the liquid inlet cavity. The number of the third liquid cutter plates is two, one third liquid cutter plate is connected with the first liquid cutter plate in a relatively covering mode to form a first nozzle channel, the other third liquid cutter plate is connected with the second liquid cutter plate in a relatively covering mode to form a second nozzle channel, and the first nozzle channel and the second nozzle channel are both bent channels, so that it can be guaranteed that the pressure of a liquid outlet is stable; therefore, the waterfall formed by spraying of the liquid knife is not prone to branching, spraying is even, and the product quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of injection devices, in particular to a double-edged liquid knife and a liquid injection 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 out uniform and equal-thickness waterfalls. Among them, liquid injection devices with liquid knives are widely used in cleaning machines, stripping machines, etching machines, coating machines and developing machines. [0003] Such as figure 1 Shown is the double-edged liquid knife currently on the market, which is only spliced ​​by the traditional single-edged liquid knife structure. The structure is bulky, and the liquid inlets need to be equipped on both sides at the same time. , takes up a lot of space, which is unfavorable for installation and debugging. On the ...
