AI Technical Summary
The coating material inside the coating die is prone to sedimentation and clumping, leading to blockage of the liquid outlet and reduced coating fluidity, which affects the coating quality.
The design employs a feed box and a circulating pump to prevent paint from settling and settling through circulation and mixing within the paint chamber. Combined with a gear pump and regulating valve to control the paint flow rate, dynamic flow and uniform mixing of the paint are achieved.
It effectively prevents paint sedimentation, improves coating quality and consistency, reduces downtime maintenance, enables gradual changes in paint composition and rapid response, and adapts to the coating needs of different substrates.

Abstract
Claims
1. A coating device characterized by comprising: include: The coating blade has a coating chamber and a discharge port communicating with one side of the coating chamber, and the coating chamber extends along the length of the coating blade. A feed box for supplying paint; the feed box is provided with a feeding port for adding paint; A feeding pump is used to transport the paint in the feeding box to one end of the paint chamber. The feeding pump is connected to the coating head and the feeding box through a pipeline. A circulation pump is used to control the return flow of paint from the other end of the paint chamber to the feed box. The circulation pump is connected to the coating blade and the paint chamber through a pipeline.
2. The coating apparatus of claim 1, wherein: The feeding pump and / or the circulating pump are gear pumps.
3. The coating apparatus of claim 2, wherein: The gear pump includes a driver, a pump housing, a driving gear, and a driven gear.
