Description

Technical Field

[0001] The present invention relates to the technical field of glue liquid guiding mechanisms, and in particular to a glue liquid guiding mechanism for coating equipment and a use method thereof. Background Art

[0002] Coating equipment refers to mechanical equipment used to evenly coat glue on the surface of substrates (such as paper, film, metal foil, cloth, etc.). This equipment is widely used in printing, packaging, electronics, textiles, construction, automobiles and other industries to produce various coating products.

[0003] The coating equipment generally includes a feeding mechanism, a diversion mechanism, a coating head and a scraping mechanism. The glue liquid is fed by the feeding mechanism, and then the glue liquid in the feeding mechanism is transported to the coating head through the diversion mechanism, sprayed on the substrate through the coating head, and then the glue liquid on the substrate is scraped flat by the scraping mechanism. Among them, the diversion mechanism is a relatively important mechanism. When there is a problem with the diversion mechanism, the flow rate of the diverted glue liquid is limited, thereby affecting the subsequent coating quality of the substrate.

[0004] During the use of the diversion mechanism, since some glue liquids are easily affected by temperature, the viscosity will increase when the temperature drops, causing the glue liquid to flow slowly in the diversion pipe and easily accumulate on the wall of the diversion pipe. As time goes by, more and more glue liquid accumulates, eventually leading to blockage of the diversion pipe. Secondly, some glue liquids contain incompletely dissolved solid particles. When these solid particles flow through the diversion pipe, they may accumulate at the elbows of the diversion pipe. When there is too much accumulation, the diversion pipe is easily blocked. When the diversion pipe is blocked to a certain extent, the flow of the glue liquid is limited. In order to ensure the coating quality, it is often necessary to reduce the operating speed of the coating equipment, which will slow down the production speed and reduce the output per unit time.
