The invention provides production equipment for a paper diaper core body. The equipment comprises a first discharging mechanism, a second discharging mechanism, a compounding mechanism and a winding mechanism, the compounding mechanism comprises a compounding rack, two material distribution mechanisms are arranged on the compounding rack in a bilateral symmetry manner, each material distribution mechanism comprises a roller assembly, two groups of roller assemblies are tangent, the equipment also comprises a discharging box assembly, a molecular pump assembly, a scraping recovery assembly anda glue spraying assembly are arranged around the roller assembly, and a vacuum device assembly is arranged in the roller assembly. According to the invention, the amount of a polymer material is accurately distributed, so that uniform distribution of the polymer material is achieved, the arranged polymer material does not deform after being shaped, the redundant polymer material is recycled in time, and waste is avoided. Pattern pieces and a module body are arranged in a split mode, when different patterns are needed, only the pattern pieces need to be replaced, the whole production module does not need to be disassembled, the replacement time is greatly saved, the pattern pieces with various different patterns can be preset, and the patterns are various.
