Description
技术领域technical field
本实用新型涉及涂布装置领域，尤其涉及一种双面涂布机构。The utility model relates to the field of coating devices, in particular to a double-sided coating mechanism.
背景技术Background technique
在锂电池行业，可以采用涂布机构在铜箔、铝箔等导电材料涂相应浆料，可以用于涂布电池的隔离膜，还可以用于涂布锂电池的正极片或负极片上相应涂层。传统的涂布机构只能进行单面涂布，效率低。因此，生产人员研究出了双面涂布系统。然而，传统的双面涂布系统的两套印刷辊上下错位安装，两个印刷辊相互配合起到相互支撑、张紧薄膜的作用，薄膜涂布处的张紧靠印刷辊的错位实现，由于印刷辊平行的，一旦来料的薄膜一边松一边紧时，松边即涂不上浆料，同时，薄膜和涂布辊的切入角不可调。In the lithium battery industry, the coating mechanism can be used to coat the corresponding slurry on conductive materials such as copper foil and aluminum foil, which can be used to coat the separator of the battery, and can also be used to coat the corresponding coating on the positive electrode or negative electrode of the lithium battery. . The traditional coating mechanism can only perform single-sided coating, which is inefficient. Therefore, production personnel developed a double-sided coating system. However, the two sets of printing rollers in the traditional double-sided coating system are installed in a dislocation up and down, and the two printing rollers cooperate with each other to support each other and tension the film. The tension of the film coating is achieved by the dislocation of the printing rollers. The printing rollers are parallel, once the incoming film is loose and tight at the same time, the loose side cannot be coated with slurry, and at the same time, the cutting angle between the film and the coating roller cannot be adjusted.
