Description

Technical Field

[0001] The utility model relates to the technical field of broken film adsorption devices, in particular to a broken film adsorption device for processing polyimide films. Background Art

[0002] In the prior art, polyimide film is usually produced by a casting method, in which a polyimide solution after high-temperature defoaming is pressed into a casting nozzle on a machine head through a stainless steel liquid storage tank through a pipeline, and a conveyor belt is arranged under the casting nozzle. The conveyor belt runs at a uniform speed, and the solution flows onto the conveyor belt and is scraped to form a polyimide film with uniform thickness. After drying and cooling, the film is peeled off from the transmission belt and sent to an imidization furnace. After high-temperature imidization, it is wound by a winder. Before entering the imidization furnace, the polyimide film needs to be deburred and punched, and an adsorption device needs to be used to adsorb and collect the broken film during the processing. Most adsorption devices use a negative pressure fan to directly collect the broken film. In this way, the stuck and tightly adhered broken film is prone to incomplete adsorption and cleaning. At the same time, large broken film accumulation inside the collection box will also affect subsequent adsorption. For this reason, we propose a broken film adsorption device for processing polyimide film. Utility Model Content
