The invention relates to a folding filter element for an air conditioner filter and a manufacturing method of the folding filter element. The folding filter element comprises a framework supporting layer (1) and surface layers welded to the two faces of the framework supporting layer. Hot-pressing grooves (2) facilitating mold pressing and folding are formed in the folding position of the framework supporting layer, and through holes evenly distributed along the hot-pressing grooves (2) are formed between the adjacent hot-pressing grooves (2). And a cavity formed by the through hole and the surface layers on the two sides of the through hole is filled with an adsorption material. Compared with the prior art, in the preparation process, the needed filter element structure can be easily formed by means of mold pressing of the folding mountain mold, the folding mountain of the filter element prepared through the method is uniform, the related size of the folding mountain is easily and accurately controlled, and the phenomenon that the melt-blown cloth fuzzes or is damaged in the process is avoided. In addition, the carbon powder and the bonding liquid are mixed firstly, and carbon filling operation is performed after the carbon powder absorbs the liquid to be saturated, so that the situation that the carbon powder is bonded everywhere and is difficult to control due to the electrostatic interaction when the non-woven fabrics are stacked is avoided.

    本发明涉及一种空调过滤器用折叠滤芯及其制造方法,该折叠滤芯包括骨架支撑层(1),以及与骨架支撑层两面焊合的表面层;所述的骨架支撑层打折处设有便于模压打折的热压槽(2),相邻热压槽(2)之间设有沿热压槽(2)均匀分布的通孔;所述的通孔与通孔两侧的表面层构成的腔体内装填有吸附材料。与现有技术相比,本发明在制备过程中借助折山模具模压可轻易形成所需滤芯结构,该方法制成滤芯的折山均一,折山相关尺寸易准确控制,且过程中熔喷布不会出现起毛或破损现象。此外,利用炭粉与粘结液先混合,待炭粉吸液饱和后再进行灌炭操作后,以避免无纺布层叠时会导致炭粉由于静电作用到处沾连、难以控制。
