Document Type and Number:
WIPO Patent Application WO/2023/072314
Kind Code:
A1
Abstract:
Disclosed in the present invention is a medical paper production equipment. The equipment comprises a yarn mesh forming unit, a yarn mesh gluing unit, a yarn mesh, upper-layer medical paper, and lower-layer medical paper combining forming unit, an upper-layer medical paper unwinding unit, a lower-layer medical paper unwinding unit, and a composite medical paper winding unit which are sequentially provided on a rack; and the described units are respectively electrically connected to a PLC controller. According to the equipment, a yarn is first woven into a grid-type yarn mesh; then the two surfaces of the yarn mesh are coated with a glue; then the yarn mesh is sandwiched between an upper-layer medical paper and a lower-layer medical paper; and then a pair of medical paper combining rolls are used to combine, by means of heating and pressurizing, the upper-layer medical paper, the yarn mesh, and the lower-layer medical paper into a medical multi-layer absorbent fiber reinforced material. The equipment has a high degree of automation, can continuously produce medical tissues in batches, and can ensure firm combination of the yarn mesh to the upper-layer paper and the lower-layer paper, and uniform yarn grids; and the material forms a specific wrinkled effect by means of bidirectional shrinkage.
