The invention discloses four-stacked net forming equipment and method for producing a coating kraft liner board. The equipment comprises a four-stacked net forming device, a pressing device, a pre-drying device, a surface sizing machine, a post-drying device, a belt calender, a curtain coater, a curtain coating post-drying device, a first blade coater, a first blade coating post-drying device, a second blade coater, a second blade coating post-drying device, a soft calendering device, a cooling device and a coiling forming device which are sequentially arranged on a machine frame. In the invention, When the coating kraft liner board is produced, the sizing is carried out on the surface layer to ensure that the uniformity of absorbing printing ink of the kraft liner board is improved; and during the coating, the respective superiorities of the curtain coating and the blade coating are combined and different raw materials with proper proportions are respectively adopted at the bottom layer, the core layer, the lining and the surface layer to ensure that the produced coating kraft liner board has the advantages of low basis weight, high strength, good bulk and high surface smoothness and can satisfy the requirements for the coating kraft liner board in different printing modes and different fields.
