A pulp molded product line with roll forming function includes a pulp suction device, a hot pressing assembly used to perform hot pressing on a pulp sucked by the pulp suction device to obtain a hot pressed pulp molded product, an edge cutting device used to perform edge cutting on the hot pressed pulp molded product to obtain an unrolled pulp molded product; and a rolling device used to perform radially inwards rolling on the unrolled pulp molded product to obtain a pulp molded product. The advantages of the pulp molded product line with roll forming function are that the waste problem of inconsistent material thickness by rolling can be solved, the raw materials can be saved and the production and processing efficiency can be improved.

The present invention relates to a dosing device (too) that is integrally made of molded pulp fiber. The dosing device (too) comprises a container portion (200) for receiving and retaining a dosage material having an opening (250) at an upper side (US) of the dosing device (too) to access the dosage material. The dosing device (too) comprises a handle portion (300) for manually moving the container portion (200) in a dosing process. The handle portion (300) is connected to an outer surface (211) of the container body (210) by a connecting portion (350) of the handle portion (300). A rim portion (252) of the container portion (200), which delimits the opening (250), and the handle portion (300) extend in a common plane (CP) and define a circumferential edge (101) of the dosing device (101). The dosing device (100) comprises a ribbing portion (400), which extends from the circumferential edge (101) at least at the handle portion (300) to a lower side of the dosing device (too), for dissipating mechanical stresses arising in the dosing process. The invention relates also to a method for manufacturing the dosing device (too) and a use of the dosing device (too) for dosing a dosage material.

Consistently-automated production machines allocated in a pulp-molding production line and a method for prepare a dried paper article (i.e. a filter tip, a cartridge container, or a component of a packaging tube) is introduced herein. It can not only resolve the technical problems of the existing pulp-molding fabrication method that is incapable of producing an elongated cylindrical/tubular component, having a ratio, greater than one, of a maximum longitudinal height thereof being relative to a maximum transverse width thereof, but can also save its working cycle time, benefit its mass production, and assure its higher product yield and quality.

An apparatus for fabricating three-dimensional paper-molded products with zero-draft angles is disclosed herein, which comprises at least one conveying rail and at least three sets of mold assemblies for sequentially applying a pre-compression, a first thermo-compression and a second thermo-compression on each semi-finished product. The at least three sets of mold assemblies are collocated, in ascending order of their transversally cross-sectional concave widths, along the at least one conveying rail. By gradually compressing the semi-finished product in sequence of compression operations of the at least three sets of mold assemblies, a specific transversally cross-sectional width of the semi-finished product are gradually and transversally widened to finalize a formation of a three-dimensional paper-molded product having zero-draft angles, thereby enhancing a structural strength of the entire product, shortening its manufacturing time and saving its manufacturing cost.
