The present invention provides a method for preparing three-dimensional filament mats by machine head and mould plate cross-gridding reciprocating motion and an apparatus thereof. According to a gridding effect, one row of filament tows, among a plurality of rows of filament tows, are swung leftward and another row of filament tows adjacent to said row are swung rightward to form a diamond-shaped grid layout in the air. When the diamond-shaped grid layout falls on a rotating forming roll (13), diamond-shaped grid nodes are bonded and cured, so that the overall structure of a three-dimensional filament mat becomes a uniformly regular cross-grid structure. Therefore, the transverse strength of a product is controlled, raw materials are reduced, energy consumption is reduced, and the market competitiveness of the product is improved.
A method for producing a three-dimensional filament mat by machine head and mould plate cross-gridding reciprocating motion, wherein a plastic raw material is plasticized by an extruder (10), the plasticized material enters a machine head (9) and a distribution plate (18) from a general flow channel, passes through a flow channel (17) in each row of single mould plate of a combined swing odd-even mould plate (8) and flows into a collection guide groove (15) for temporary storage, then passes through a tow outlet (16) to uniformly extrude a filament tow;
An apparatus of machine head and mould plate cross-gridding reciprocating motion for producing a three-dimensional filament mat, wherein the machine head (9) is fixedly connected to the extruder by means of the flow channel, an upper end of the machine head (9) is connected to the distribution plate (18), the mould plate under the distribution plate (18) is a split combined structure, a left swing device (11) and a right swing device (12) are respectively fixed on both sides of the machine head (9), the two swing devices separately drive a corresponding mould plate to swing leftward and rightward along a bottom groove of the machine head (9), and the bottom groove is mechanically sealed with the machine head (9).
