The invention relates to a full-automatic paper diaper packaging
production line which comprises a stacking
machine, pre-
compression device, a transition mechanism, a secondary
compression device, a bag feeding device, a bag opening device, a packaging, sealing and
cutting-off device, a pushing mechanism and an offcut collecting device. The pre-
compression device comprises a support, a support plate, a left compression mechanism, a right compression mechanism and a
push out mechanism, wherein each of the left compression mechanism and the right compression mechanism comprises a compression translation mechanism, an upper push block and a lower push block, the upper push block and the lower push block are respectively connected with the
power output end of the compression translation mechanism, and the upper push block is located above the lower push block. The full-automatic paper diaper packaging
production line has the advantages that the upper push blocks and the lower push blocks are respectively driven by independent compression translation mechanisms and are fixed in the middle to perform pre-compression, paper diapers are prevented from being deviated and stuck, production smoothness is increased, and production efficiency is increased; the upper push blocks are separated from the lower push blocks, the friction between the paper diapers and the upper push blocks and the lower push blocks is reduced, and abrasion and scratch of the paper diapers are avoided.
